Description

Technical Field

[0001] This utility model relates to the technical field of LED lighting devices, specifically to an LED lamp and an assembly method for the LED lamp. Background Technology

[0002] LED lighting fixtures are those that use light-emitting diodes (LEDs) as their light source. They are widely used due to their advantages such as energy saving and long lifespan. Panel lights among LED lighting fixtures are particularly popular because of their thinness, large illumination area, and simple, complete light-emitting surface design.

[0003] Existing LED panel lights include two types: side-emitting and direct-lit. Side-emitting LED panel lights have low light efficiency and high cost, while direct-lit LED panel lights have relatively simple technology and processes and lower cost, but they are thicker and have higher transportation costs.

[0004] Existing LED panel lights typically have a frame to secure the components or parts within the LED panel light. Some related technologies use welded frames, which are more robust but also more expensive and prone to deformation or damage from impacts or drops. Other related technologies use frames secured with screws or similar materials, which involve complex assembly processes and increase costs and defect rates.

[0005] Existing LED panel lights typically include a power supply unit to drive the LED light source. Because the size of this power supply unit is limited by the size of electronic components, making large-scale adjustments difficult, the bezel width of the LED light fixture is relatively wide, for example, around 25mm. This results in the bezel occupying a large proportion of the LED light-emitting surface, which limits both visual appeal and light output.

[0006] In addition, because LED light sources typically have many LED chips, it is difficult to reduce the height of LED luminaires in order to achieve uniform light output.

[0007] In summary, given the shortcomings and defects of existing LED panel lights, how to design LED panel lights to reduce damage during transportation, improve light output, increase assembly efficiency, enhance visual effects, and reduce height / thickness is a technical problem that urgently needs to be solved by those skilled in the art.

[0104] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0105] In the following description, reference is made to the accompanying drawings, which illustrate several embodiments of the present invention. It should be understood that other embodiments may also be used, and changes in module or unit composition, electrical and operational aspects may be made without departing from the spirit and scope of this disclosure. The following detailed description should not be considered limiting, and the scope of the embodiments of the present invention is defined only by the claims of the published patents. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the present invention.

[0106] It will be understood that although the terms first, second, etc., may be used herein to describe various elements or parameters in some instances, these elements or parameters should not be limited by these terms. These terms are used only to distinguish one element or parameter from another. For example, a first inclined portion may be referred to as a second inclined portion, and similarly, a second inclined portion may be referred to as a first inclined portion, without departing from the scope of the various described embodiments. Both the first inclined portion and the second inclined portion describe an inclined portion, but they are not the same inclined portion unless the context otherwise clearly indicates otherwise. The terms “or” and “and / or” as used herein are to be interpreted inclusively, or mean any one or any combination thereof. Thus, “A, B, or C” or “A, B, and / or C” means any of the following: A; B; C; A and B; A and C; B and C; A, B, and C. Exceptions to this definition will only occur if the combination of elements, functions, steps, or operations is inherently mutually exclusive in some way.

[0107] It will be understood that when an element, such as a layer, region, or substrate, is referred to as being "on" another element or extending "on" another element, the element may be directly on or directly extending onto the other element, or intermediate elements may exist. Conversely, when an element is referred to as being "directly on" another element or "directly extending onto" another element, no intermediate elements exist. It will also be understood that when an element is referred to as being "connected" or "attached" to another element, it may be directly connected or attached to the other element, or intermediate elements may exist. Conversely, when an element is referred to as being "directly connected" or "directly attached" to another element, no intermediate elements exist.

[0108] Relative terms such as “below,” “above,” “upper,” “lower,” “horizontal,” or “vertical” may be used herein to describe the relationship between one element, layer, or region and another element, layer, or region illustrated in the figures. It will be understood that these terms are intended to cover different device orientations other than those depicted in the figures. In this invention, “vertical,” “horizontal,” and “parallel” are defined as including cases within ±10% of their standard definitions. For example, vertical typically refers to an angle of 90° relative to a reference line, but in this invention, vertical refers to cases including those within 80° to 100°.

[0109] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. When used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that, when used herein, the terms “comprising,” “including,” “containing,” and / or “comprising” designate the presence of the stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or combinations thereof.

[0110] Unless otherwise specified, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It will also be understood that terms used herein shall be interpreted as having the meaning consistent with their meaning in the context of this specification and the relevant field, and shall not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0111] Unless otherwise explicitly stated, comparative quantitative terms (such as "above" and "below") are intended to encompass the concept of equality. As an example, "above" can mean not only "greater than" in a mathematical sense, but also "equal to".

[0112] This utility model discloses an LED lighting fixture in some embodiments, which can be suspended or fixedly installed to the ceiling or suspended ceiling. Depending on the application, the LED lighting fixture disclosed in this utility model may also be called a panel light, flat panel light, chandelier, recessed light, concave light, recessed light, ceiling light, etc.

[0113] Please see Figure 1 The figure shows a three-dimensional structural diagram of an LED lamp in one embodiment of the present invention. As shown in the figure, the LED lamp includes a base 1 and a power supply device 2, and the power supply device 2 is connected to the base 1.

[0114] In some examples, the power supply 2 is connected to the base 1 in a replaceable (removable) manner so that the power supply 2 can be replaced for the LED lamps.

[0115] In another embodiment, the power supply device 2 can also be connected to the base 1 in a non-removable manner, that is, after the power supply device 2 is fixed to the base 1, it cannot be easily disassembled or requires destructive disassembly. During packaging and transportation, the base 1 and the power supply device 2 are packaged and transported together.

[0116] In another embodiment, the power supply device 2 can be configured to be quickly installed with the base 1. After installation, the power supply device 2 and the base 1 cannot be easily disassembled or require destructive disassembly. Thus, during packaging and transportation, the power supply device 2 and the base 1 can be packaged and transported separately, saving packaging and transportation costs. When selling or using, the power supply device 2 and the base 1 can be quickly installed.

[0117] In one embodiment, the LED luminaire further includes a light source assembly disposed on the base. See also... Figure 2 The figure shows a three-dimensional structural diagram of the light source assembly and the base in one embodiment of the present invention. As shown, the base 1 includes a base plate 10 and side walls 11. The side walls 11 surround the base plate 10 (or periphery) and form a receiving groove 14 with the base plate 10, which can also be referred to as a receiving space. The light source assembly 3 is further disposed on the base plate 10 and located within the receiving groove 14. The light source assembly 3 may include a circuit board 30 and a light-emitting element 31. The circuit board 30 is attached (e.g., directly attached or attached through an intermediate medium) to the base plate 10 so that the circuit board 30 dissipates heat through the base plate 10. The base plate 10 may be made of metal or plastic. The light-emitting element 31 may be an LED bead or other type of LED light-emitting unit. The light-emitting elements 31 may be configured in multiple groups, each group may include one or more light-emitting elements 31, and the multiple groups of light-emitting elements 31 are evenly distributed on the circuit board 30. Figure 2 In the example, eight groups of light-emitting elements 31 are arranged, with each group including two light-emitting elements 31. Those skilled in the art can set any number of light-emitting elements 31 according to actual needs. That is, the light-emitting elements 31 are attached to one side of the circuit board 30, while the other side of the circuit board 30 is attached to the base plate 10.

[0118] In some embodiments, multiple light emitters 31 can also be arranged on the circuit board 30 in a non-uniform distribution manner. That is, a larger number of light emitters 31 can be arranged in a local area to form a region with a higher density of light emitters 31, and a smaller number of light emitters 31 can be arranged in a local area to form a region with a lower density of light emitters 31. By configuring the light emitters 31 with different densities in different regions, the light emission effect can be adjusted and designed.

[0119] In some embodiments, the light source assembly 3 can be configured as multiple groups, each group arranged in parallel on the base plate 10, and each group of light source assembly 3 can be connected via wiring elements 7. For example, the light source assembly 3 can be configured as 2 groups, 3 groups, 4 groups, 5 groups, or 6 groups, etc. Figure 2 In the example shown, the light source component 3 is set to 6 groups.

[0120] Of course, in other embodiments, the light source component 3 may be set to only one group, and those skilled in the art can select any number of groups to configure on the base plate 10 according to actual needs.

[0121] The light source assembly 3 is further electrically connected to the power supply device 2 via wiring element 7. In some embodiments, the power supply device 2 may be disposed within the receiving slot 14 (i.e., the area / space of the receiving slot 14 for accommodating or arranging the light source assembly 3) to drive the light source assembly 3 to emit light via the wiring element 7. In some embodiments, the power supply device 2 may also be disposed outside the receiving slot 14 (e.g., on the back of the receiving slot 14), such as... Figure 2 As shown, a wiring port 112 is provided on the side wall 11, and the wiring element 7 passes through the wiring port 112 to be electrically connected to the power supply device 2.

[0122] In one embodiment, the LED lamp may further include a light processing unit for processing the light emitted from the light source assembly 3. The methods for processing the emitted light include, but are not limited to, diffusion, projection, refraction, reflection, diffraction, and transmission. Figure 2 In the embodiment shown, the light processing unit includes a lens 32 covered on the light-emitting body 31, and the lens 32 is configured in a one-to-one correspondence with the light-emitting body 31.

[0123] like Figure 2 As shown, the base 1 also includes a mounting portion 12, which is disposed along the edge of the side wall 11 and is generally parallel to the base plate 10. The mounting portion 12 is used to fix at least a portion of the structure or components in the LED lamp. For example, such as... Figure 1 As shown, the LED luminaire also includes a suspension mechanism 6, which can be directly or indirectly fixed to the mounting portion 12 for mounting the LED luminaire within the lighting space. For example, the suspension mechanism 6 can be configured as a hook, slide rail, bracket, etc., to set the LED luminaire within the installation area of ​​the lighting space. Furthermore, the light processing unit of the LED luminaire may include optical components fixed to the mounting portion 12 to cover the receiving groove 14.

[0124] Please see Figures 3 to 5 , Figure 3 The diagram shown is a partial disassembled structural diagram of an LED lamp according to one embodiment of the present invention. Figure 4 This utility model is shown in Figure 3A partial enlarged view of region A in the illustrated embodiment. Figure 5 This utility model is shown in Figure 1 A schematic diagram of section II from one viewing angle in the illustrated LED lighting fixture embodiment. (See diagram below.) Figures 3 to 5 As shown, the light processing unit may include an optical component 4, which is fixed to the mounting portion 12 and covers the receiving groove 14. The optical component 4 may be, for example, a diffuser plate, used to diffuse the light generated by the light source assembly 3 to increase light uniformity and reduce glare from the lamp. For example, the optical component 4 may be made of PC material or acrylic sheet, which has light diffusion function due to its material properties; or, the optical component 4 may also be made of transparent material, such as glass or transparent plastic, and a diffusion layer may be provided on its surface to give it light diffusion function. Figures 3 to 5 In the embodiment shown, the LED lamp also includes a frame 5, through which the optical component 4 is fixed to the mounting part 12.

[0125] In one embodiment, such as Figures 3 to 5 As shown, the frame 5 is used to fix the optical component 4 to the mounting portion 12. The frame 5 includes a frame 50 and may further include a connector 51. The frame 50 is sleeved on the mounting portion 12 to clamp the optical component 4 onto the mounting portion 12. Specifically, the optical component 4 covers the receiving groove 14 and the edge of the optical component 4 is abutted against the side of the mounting portion 12 facing the light source assembly 3. The frame 50 is sleeved on the mounting portion 12 and the optical component 4 to clamp the mounting portion 12 and the optical component 4, thereby fixing the optical component 4. The connector 51 is used to connect two adjacent frames 50 to position multiple frames 50 around the mounting portion 12.

[0126] In one embodiment, the number of frame edges 50 and connectors 51 corresponds to the number of sides of the mounting portion 12, so that the connectors 51 connect multiple frame edges 50 end to end to form a frame 5 corresponding to the shape of the mounting portion. For example, the base plate 10 can be set as a polygon, and the sidewalls 11 and the mounting portion 12 can also be set as a ring structure corresponding to the number of sides of the polygon, with the number of frame edges 50 and connectors 51 corresponding to the number of sides of the mounting portion 12. Figures 3 to 5In the illustrated embodiment, the base plate 10 is quadrilateral, and the sidewall 11 is configured as a quadrilateral annular structure surrounding the base plate 10. The mounting part 12 is configured around the edge of the sidewall 11, corresponding to a quadrilateral annular structure. The frame 5 has four sidewalls 50 and four connectors 51. Each connector 51 connects two adjacent sidewalls 50 end to end, thereby forming a quadrilateral frame 5. It should be understood that the above shapes are merely examples. The base plate 10 can also be configured as a triangular, pentagonal, hexagonal, or other irregular shape, with the mounting part 12 correspondingly configured as an annular structure with a corresponding number of sides. The sidewalls 50 and connectors 51 can also be configured as three, five, or six, respectively, to form a polygonal frame such as a triangular, pentagonal, or hexagonal frame. Under the guidance of the above embodiments, the base plate 10 can also be circular, with the mounting part 12 correspondingly configured as an annular structure. Here, the frame 5 may only include the sidewalls 50, which are configured as annular structures adapted to the mounting part 12.

[0127] Please see Figure 6 and Figure 7 The following are respectively shown as the present utility model. Figure 5 Enlarged partial views of region B in different embodiments of the illustrated example, such as... Figure 6 and Figure 7 As shown, the mounting portion 12 protrudes towards the side opposite to the light emission of the light source assembly to form a bent fixing portion 120. The frame 50 includes a clamping portion 500 and a bent portion 501. The clamping portion 500 has a clamping space adapted to the mounting portion 12. During assembly, after the optical component 4 is attached to the mounting portion 12, it can be inserted into the clamping space of the clamping portion 500. The bent portion 501 is formed to extend along the clamping portion 500 and is fastened to the bent fixing portion 120 to position the frame 50. Specifically, during assembly, after the optical component 4 and the mounting portion 12 are inserted into the clamping portion 500, the bent portion 501 can be bent towards the bent fixing portion 120 along the pre-formed bending point 502 by a bending process to fasten with the bent fixing portion 120. In this way, the frame 50 can be clamped to the mounting portion 12 without additional fixing, greatly reducing the defect rate or process complexity caused by the use of screws or other fasteners. Of course, the assembly process can also be described as follows: after the optical component 4 and the mounting part 12 are matched, the clamping part 500 is sleeved on the outside of the component composed of the optical component 4 and the mounting part 12, and then the bending part 501 is bent towards the bending fixing part 120 along the pre-formed bending point 502 by the bending process so as to be fastened with the bending fixing part 120.

[0128] To further increase the stability of the frame clamping, in one embodiment, the clamping part 500 is provided with a positioning protrusion 5000 on the side facing the optical component 4. The positioning protrusion 5000 further clamps the optical component 4 more firmly in the clamping part 500 to prevent the optical component 4 from shaking or falling off.

[0129] In one embodiment, such as Figure 7 As shown, the end of the frame 50 near the optical component 4 (here, the end can be understood as the termination end of the frame 50 that fits against the optical component 4) has a certain slope. In other words, the end face of the frame 50 near the optical component 4 is set as a slope. This slope or slope can, to a certain extent, enable the frame 50 and the optical component 4 to have a better bonding effect, thereby improving the overall visual effect of their combination.

[0130] In one embodiment, such as Figure 4 As shown, the connector 51 includes corner protectors 510 and guides 511. The corner protectors 510 are set with an arc angle to prevent deformation or damage in case of drops or impacts to the lamp. The number of guides 511 is set to the number of the corresponding frame 50 connected to the connector 51. Figure 4 For example, two guide portions 511 are provided, located on the sides of the corner protectors 510 facing the two side frames 50 respectively, and the side frames 50 are provided with corresponding slots 503 for the guide portions 511, so that the connector 51 is connected to the side frame 50 by inserting the guide portion 511 into the slot 503. For example, the guide portion 511 and the slot 503 can be interference-fitted to prevent loosening. The guide portion 511 and the slot 503 can also be provided with a matching engagement structure, which prevents loosening through the engagement of the two engagement structures. Furthermore, in cases such as... Figure 4 In the embodiment shown, the corner protector 510 also has a clamping space toward the mounting portion 12, which allows the mounting portion 12 to enter so that the connector 51 can position the frame 50 around the mounting portion 12.

[0131] Corresponding to, for example Figures 1 to 7 In some embodiments of the LED lamp described in any of the embodiments, this utility model also provides an assembly method for the LED lamp.

[0132] The assembly method for the LED lamp includes the following steps: providing a base including a base plate, side walls, and a mounting portion; covering the base with an optical component and fitting it to the mounting portion; fitting a frame onto one side of the mounting portion and the optical component such that the clamping portion of the frame clamps the mounting portion and the optical component; bending the bent portion towards the bending fixing portion of the mounting portion along the bending point of the frame using a bending process; inserting a guide portion of a connector into the first end of the frame; fitting another frame onto the other side of the mounting portion and the optical component (this other side is adjacent to the first side), and inserting the tail end of the other frame into another guide portion of the connector; bending the bent portion towards the bending fixing portion of the mounting portion along the bending point of the other frame using a bending process; inserting a guide portion of another connector into the first end of the other frame; repeating this process until a ring structure is formed around the mounting portion. Further, the assembly method may also include steps such as fixing a power supply device to the mounting portion and fixing a suspension mechanism to the mounting portion.

[0133] Please see Figures 8 to 1 1, Figure 8 The diagram shown is a three-dimensional structural schematic of an LED lamp with the folded portion unfolded (unfolded) in one embodiment of the present invention. Figure 9 The diagram shown is a three-dimensional structural schematic of the LED lamp after the folding part is folded in one embodiment of the present invention. Figure 10A This utility model is shown in Figure 8 The diagram shows a cross-section II-II in one embodiment of the LED lighting fixture. Figure 11A This utility model is shown in Figure 10A A magnified view of region C in the illustrated embodiment.

[0134] like Figures 8 to 1 The basic architecture of the LED lamp provided in the embodiment shown in Figure 1 is similar to... Figures 1 to 7 The LED lamps provided in any embodiment are similar, except that the LED lamps no longer have a frame, and the base 1, in addition to the base plate 10, side walls 11, and mounting portion 12, further includes folding portions 13. In one example, the number of folding portions 13 corresponds to the number of sides of the mounting portion 12, for example... Figures 8 to 1 As shown in Figure 1, the mounting portion 12 is configured as a quadrilateral ring structure, and folding portions 13 are respectively provided on each side of the mounting portion 12, that is, four folding portions are provided. The folding portions 13 are folded towards the optical component 4 (in the direction shown by the dotted arrow in Figure 11) to fix the optical component 4 (as shown in the figure). Further, in order to prevent the folding portions 13 from overlapping, the two ends of the folding portions 13 can be set as bevels (for example, the folding portions 13 are trapezoidal) so that when the folding portions 13 are folded to fit the optical component 4, the bevels of two adjacent folding portions 13 are joined together, further making the light-transmitting surface formed by the optical component 4 a quadrilateral corresponding to the shape of the base plate 10 (as shown in the figure). Figure 9 As shown in the figure, this ensures the light output effect.

[0135] In other examples, the number of folds 13 may not be the same as the number of sides of the mounting portion 12. For example, in an example where the mounting portion 12 is a ring structure, any number of folds 13 may be formed on the edge of the mounting portion 12.

[0136] In one embodiment, such as Figures 8 to 1 As shown in Figure 1, the mounting part 12 protrudes towards the base plate 10 to form a mounting groove 121. The mounting groove 121 is used to allow a fastener to enter and pass through to fix the structure or component in the LED lamp. For example, the fastener is a screw, which enters and passes through the mounting groove 121 to fix the power supply device 2 and / or the suspension mechanism 6. In this way, the fastener is built into the LED lamp and does not affect the aesthetics.

[0137] Corresponding to, for example Figures 8 to 1 The present invention also provides an assembly method for the LED lamp in some embodiments, comprising the following steps: providing a base including a base plate, side walls, a mounting portion, and a folding portion; covering the base with an optical component and abutting it against the mounting portion; folding the folding portion toward the optical component to abut it against the optical component. The method may further include inserting a fixing member into a mounting groove on the mounting portion before covering the optical component with the base for fixing a power supply device and / or a suspension mechanism;

[0138] Figure 10B This utility model is shown in Figure 8 The diagram shows a cross-section II-II of the LED luminaire in another embodiment. Figure 11B This utility model is shown in Figure 10B A magnified view of region C in the illustrated embodiment. Figure 10B and Figure 10A The difference lies in whether the edge of optical component 4 is a sloping surface, such as... Figure 10A The folding part 13 fits against the inclined surface, allowing for the fixation of the optical component 4 after a small-angle bend.

[0139] Given that the size of the power supply device in related technologies is often difficult to adjust, the width of the mounting portion formed at the edge of the sidewall needs to be relatively wide to provide sufficient installation space for the power supply device. This further results in a wider obstruction area on the light-emitting surface, affecting the light emission effect and the overall visual effect of the product. In some embodiments provided by this utility model, by setting the sidewall of the base to have at least two inclined portions to increase the width of the installation space for the power supply device, the obstruction area can be minimized, improving the proportion of the light-emitting surface and the light emission effect. At the same time, the inclined portions make the transition between the mounting portion formed at the edge of the sidewall and the light-emitting surface smooth, unlike the obvious stepped structure formed between the edge of the mounting portion and the light-emitting surface in traditional designs, resulting in a more complete overall product surface shape. The following embodiments use the example of setting two inclined portions on the sidewall, but it should not be construed as a limitation on the number of inclined portions.

[0140] Wherein, the light-emitting surface refers to the light-emitting surface of the lamp, in order to Figures 1 to 1 Taking the embodiment shown in Figure 1 as an example, the light generated by the light source assembly 3 is projected through the optical component 4, so that a light-emitting surface of the lamp is formed on the optical component 4. Since the edge of the optical component 4 is fixed to the mounting portion 12, the part where the optical component 4 and the mounting portion 12 are joined is generally not translucent. Therefore, a fixing mechanism is usually provided to fix the optical component 4 to the mounting portion 12, and the fixing mechanism can also block the non-light-emitting area on the optical component 4 to form a clearly defined blocking area with the optical component 4. Figures 1 to 7 Taking the illustrated embodiment as an example, the fixing mechanism is correspondingly set as frame 5, the blocking area is the part of the frame 50 located on the light-emitting surface side of the optical component 4, and the width of the blocking area is corresponding to... Figure 6 and Figure 7 The shown border 50 has a width d1. Figures 8 to 1 In the embodiment shown in Figure 1, the fixing mechanism corresponds to the folding part 13, the blocking area corresponds to the part of the folding part 13 that is attached to the optical component 4 after being folded, and the width of the blocking area corresponds to the side width d2 of the folding part 13 shown in Figure 11.

[0141] In one embodiment, such as Figure 2As shown in Figure 11, the sidewall 11 of the base 1 includes a first inclined portion 110 and a second inclined portion 111 compliantly disposed (the first inclined portion 110 and the second inclined portion 111 compliantly disposed means that the second inclined portion 111 is connected to the first inclined portion 110 to form the base). Referring to Figure 11, the first inclined portion 110 is connected to the edge of the base plate 10 and is inclined relative to the base plate 10, with an included angle α relative to the base plate 10. The second inclined portion 111 is connected to the first inclined portion 110 and has a different inclined angle relative to the base plate 10, with the included angle β equal to that in Figure 11. In one embodiment, the inclined angle of the second inclined portion 111 relative to the base plate 10 is greater than the inclined angle of the first inclined portion 110 relative to the base plate 10, that is, the included angle β is greater than the included angle α. It should be understood that this embodiment is described using the diagram shown in Figure 11 as an example, and the sidewall 11 of the LED lamp provided in any embodiment of this utility model can be configured with this structure or adopt other structures.

[0142] In this embodiment, the first inclined portion 110, the second inclined portion 111, and the mounting portion 12 form a configuration space outside the receiving groove 14. The width S of this configuration space is composed of the projected width s1 of the first inclined portion 110 and the second inclined portion 111 in the direction of the base plate 10 and the projected width s2 of the mounting portion 12 in the direction of the base plate 10. Compared to a sidewall with only a single inclined portion, the provision of two inclined portions (110, 111) in this embodiment increases the configuration width available from the sidewall, greatly reducing the width requirement for the mounting portion 12, and further significantly reducing the width of the obstruction area on the optical component 4. That is, the side width of the fixing mechanism on the light-emitting surface side of the optical component 4 is reduced. For example, Figure 6 and Figure 7 The width d1 of the frame 50, which serves as the fixing mechanism, and the width d2 of the folding part 13, which serves as the fixing mechanism, in Figure 11 can be set to be relatively small.

[0143] In one embodiment, the width of the obstructed area can be controlled to be less than 15 mm. More specifically, it can be controlled to be less than 12 mm. Figures 1 to 7 Taking the illustrated embodiment as an example, the width d1 of the frame 5's border 50 can be controlled to be below 15mm. Figures 8 to 1 Taking the embodiment shown in Figure 1 as an example, the side width d2 of the folded portion 13 can be controlled to be less than 15mm. Further, as... Figures 1 to 7 The side width d1 mentioned in the text or as shown Figures 8 to 1 The side width d2 shown in Figure 1 can be controlled to be below 12mm. It should be understood that the width exemplified in this embodiment is only one example, and those skilled in the art can adjust the angles of the two inclined portions (110, 111) according to actual needs to further increase or decrease the configuration width provided by the sidewall, and correspondingly further decrease or increase the width of the shading area.

[0144] In one embodiment, to avoid forming dark areas on the sidewalls, the tilt angle α of the first inclined portion 110 relative to the base plate 10 can be set to any angle between approximately 95° and 175°. More preferably, it is set to any value between 140° and 150°.

[0145] Preferably, the optimal setting is any angle between approximately 142° and 146°. Further, in embodiments where multiple light source assemblies are configured, the distance between the light source assembly closest to the sidewall and the sidewall is less than the distance between that light source assembly and its adjacent light source assembly.

[0146] In one embodiment, to maximize the use of the configuration space, one side of the power supply device 2 is fitted against the sidewall 11. For example, one side of the power supply device 2 is fitted against the connection between the first inclined portion 110 and the second inclined portion 111 on the sidewall 11. Further, to ensure a better fit between the power supply device 2 and the sidewall 11, in one embodiment, at least one side of the power supply device 2 that is fitted against the sidewall 11 is configured as a curved edge, and the connection between the first inclined portion 110 and the second inclined portion 111 forms a transition region adapted to the curved edge, so that the curved edge of the power supply device 2 fits onto the transition region.

[0147] In one embodiment, as shown in FIG11, the power supply device 2 is fixed to the base by a power supply box 20, which protects and secures the power supply device 2. For example, the power supply box 20 is fixed to the mounting part 12 (as shown in FIG11, a screw enters and passes through the mounting groove 121 to tighten the power supply box 20) so that the power supply device 2 is located in the configuration space formed outside the receiving groove 14. The power supply device 2 may include a circuit assembly 21, which may include a circuit board, as well as several electronic components and wiring components. The electronic components may be disposed on the circuit board corresponding to the power supply device 2, or some of them may be disposed on the circuit board corresponding to the light source assembly, so as to share the same circuit board with the light source assembly.

[0148] Due to the height limitation of the power supply unit, the LED lamps provided in related technologies are relatively tall, resulting in higher costs during packaging and transportation. Therefore, in some embodiments of this utility model, the power supply unit protrudes from the base plate when placed in the configuration space, so that when two LED lamps are placed together with the base plate, they have an overlapping area in the vertical direction. Here, the vertical direction refers to the direction of the height or thickness of the LED lamp; that is, the power supply unit protrudes from the base plate in the thickness direction.

[0149] It should be noted that, in order to reduce the height and width of the LED lamps, in embodiments with a power supply box, the surface of the power supply device near the power supply box is attached to the corresponding inner wall of the power supply box. Taking Figure 11 as an example, the power supply box 20 is configured as a generally L-shaped shell adapted to the configuration space, and the power supply device 2 is configured as a generally rectangular shape and located inside the power supply box 20 by attaching to the two inner walls of the power supply box 20. Therefore, within the allowable error range, the dimensional information of the power supply device relative to the base plate mentioned in some embodiments of this invention with a power supply box can be understood as the dimensional information of the power supply box relative to the base plate, which can be directly obtained by measuring the dimensional information of the power supply box relative to the base plate.

[0150] Please see Figure 12 and Figure 13 And in conjunction with Figure 11, Figure 12 The diagram shown illustrates two LED lamps placed together with a base plate in one embodiment of the present invention. Figure 13 This utility model is shown in Figure 12 A partial enlarged view of region D in the illustrated embodiment. Figure 11 shows the height h by which the power supply device 2 protrudes from the base plate 10, that is, the base plate 10 and the power supply device 2 have a height difference h. Figure 12 and Figure 13 As shown, the distance from the surface of the base plate 10 of the first LED lamp T1 and the second LED lamp T2 away from the surface of the optical component 4 to the surface of the optical component 4 away from the base plate 10 is p, which can be called the main body height of the LED lamp.

[0151] When the first LED lamp T1 and the second LED lamp T2 are placed together on the base plate, they have an overlapping area M in the vertical direction. The overlapping area M is the area formed by the height difference between the base plate 10 and the power supply device 2, i.e. Figure 13 The region corresponding to the height h. Specifically, when the base plate 10 of the first LED lamp T1 is attached to the base plate 10 of the second LED lamp T2, the base plate 10 of the first LED lamp T1 will be located in the region corresponding to the height difference h between the base plate 10 of the second LED lamp T2 and the power supply device 2, while the base plate 10 of the second LED lamp T2 will be located in the region corresponding to the height difference h between the base plate 10 of the first LED lamp T1 and the power supply device 2. Of course, in some embodiments, the power supply device 2 may also be configured not to protrude from the base plate 10 (not shown). For example, the power supply device 2 is flush with the base plate 10, that is, as shown in Figure 11, the height difference h between the power supply device 2 and the base plate 10 does not exist, that is, the height difference is zero, and the height of the power supply device 2 just reaches the plane where the base plate 10 is located.

[0152] To ensure better fit between the two LED lamps and maximize the use of the overlapping area, in one embodiment, as shown in FIG11, the side wall 11 of the power supply box 20 for accommodating the power supply device 2 near the base plate 10 is inclined relative to the base plate 10. The angle γ of this inclination corresponds to the inclination angle α of the first inclined portion 110. For example, the angle γ of this inclination is equal to the inclination angle α of the first inclined portion 110. When the angle γ and the inclination angle α correspond, during stacking, the first inclined portion 110 of one LED lamp and the side wall 11 of the power supply box 20 of the other LED lamp, which is inclined near the base plate 10, can fit perfectly (parallel), improving the stability of the stacked arrangement.

[0153] In another embodiment of this utility model, the tilt angle γ is greater than the tilt angle α of the first tilted portion 110. When the tilt angle γ is greater than the tilt angle α of the first tilted portion 110, that is, in the space where the tilt angle γ is located, the included angle space formed by the base plate 10 and the side wall 11 of the power box 20 near the base plate 10 can completely accommodate the included angle portion formed by the base plate 10 and the first tilted portion 110, thereby ensuring that, as in... Figure 12 When the LED lights are stacked, the first tilting part 110 does not interfere with the power supply box 20. Furthermore, two LED lights can be stacked... Figure 12 The packaging and transportation method shown reduces the vertical height compared to packaging and transporting a single LED light fixture. This is because the two LED light fixtures overlap, reducing the overall height (by 2×h) of the two power supply units 2 protruding from the base plate 10. Figure 13 Taking the example shown, when two LED lamps are placed together with the base plate 10, the height h of the power supply device 2 of the first LED lamp T1 protruding from the base plate 10 overlaps with the height of the base plate 10 of the second LED lamp T2 from the optical component 4. Similarly, the height h of the power supply device 2 of the second LED lamp T2 protruding from the base plate 10 overlaps with the height of the base plate 10 of the first LED lamp T1 from the optical component 4. Therefore, the height of the power supply device 2 protruding from the base plate 10 does not occupy the total height (or total thickness) of the two LED lamps. Figure 12 The arrangement shown has a total height equal to the sum of the main body heights of the two LED lamps, i.e., 2×p. In this embodiment, the main body height refers to the distance from the surface of the base plate 10 away from the optical component 4 to the surface of the optical component 4 away from the base plate 10. The height of the power supply device can also be referred to as the thickness of the power supply device, which can be understood as the overall height or thickness of an LED lamp. It corresponds to the distance between the side of the power supply device located in the base plate direction and the optical component. In embodiments where the power supply device is configured in a power box, it can also correspond to the distance between the side of the power box located in the base plate direction and the optical component.

[0154] In one embodiment, the power supply device 2 can protrude from the base plate 10 by lowering the height of the base plate 10 from the optical component 4. In one example, by arranging the power supply device in the configuration space formed by the aforementioned first inclined portion, second inclined portion, and mounting portion, the height of the power supply device or the overall height of the LED lamp can be controlled to be less than 40mm, and further, less than 35mm. Lowering the height of the base plate 10 from the optical component 4 while meeting the light emission requirements allows the distance between the base plate 10 and the optical component 4 to be controlled to be less than 35mm, and further, less than 30mm. For example, the height of the power supply device or the overall height of the LED lamp can be set to 35mm, and the height of the base plate 10 can be set to 30mm. Thus, compared to packaging and transporting individual LED lamps separately, Figure 12 and Figure 13 Packaging and shipping as shown can reduce the height by 10mm.

[0155] In one embodiment, the overall height of the LED lamp is less than or equal to 6 / 5 of the height of the power supply device, that is, the height of the power supply device protruding from the base plate 10 is less than or equal to 1 / 5 of the main body height p of the LED lamp. Figure 12 and Figure 13 The packaging and transportation method shown can reduce the overall height of the two LED lamps by at least 1 / 6, that is, the reduction in height is greater than or equal to 1 / 6 of the overall height of the two lamps.

[0156] In some embodiments, the height of the power supply protruding from the base plate 10 is less than or equal to 1 / 15 of the height of the base plate, for example, less than or equal to 2 mm.

[0157] Corresponding to, for example Figures 8 to 13 The lamp structure and placement shown in the illustration, in some embodiments of this utility model, can also provide a packaging method for an LED lamp, including the following steps: providing an LED lamp, the LED lamp being, for example, equipped with the features of this utility model. Figures 8 to 1 1. An LED luminaire with the structure of any embodiment; placing another LED luminaire with its base plate bonded to the base plate of an LED luminaire; packaging the two LED luminaires. In some embodiments, before bonding the other LED luminaire to an LED luminaire, a diaphragm may be provided on the base plate of the LED luminaire, the diaphragm being, for example, a film of foam or other soft material. It should be understood that the bonding described in any embodiment of the present invention can refer to direct bonding or bonding through a medium, and does not necessarily require direct contact bonding.

[0158] Please see Figure 14 and 15This is a schematic diagram and its corresponding exploded view of an LED lamp in another embodiment of the present invention. Except for the optical component 4 and the frame 5, which are significantly different from those in the above embodiment, the other components are basically the same, so they will not be described again below.

[0159] Combining the same 14 and Figure 15 As shown, in this embodiment, the optical component 4 consists of a first light processing unit 40, at least two second light processing units 41 connected to the first light processing unit 40, and a third light processing unit 42 corresponding to the second light processing unit 41. The first light processing unit 40 is an arc surface with light transmission and light diffusion functions. It is made of PC, resin, acrylic sheet or latex and protrudes towards the base plate 10. Two second light processing units 41 are respectively disposed on opposite sides of the first light processing unit 40. Each second light processing unit 41 has a micro-optical structure on its surface. This micro-optical structure can be a patterned structure arranged in an array, such as protrusions or depressions of a certain shape. These protrusions and depressions cause some of the light emitted from the light source assembly 3 to become disordered. That is, the light emitted from the light source assembly 3 undergoes one or more optical processing functions such as transmission, refraction, and reflection through the micro-optical structure at least once, dispersing the light emitted from the same area to different directions, thereby homogenizing the light. It is made of PC, resin, acrylic sheet, or latex, and the surface is integrally formed by methods such as embossing, printing, injection molding, or molding of the micro-optical structure. The second light processing unit 41 can cause the light emitted from the light source assembly 3 to diffuse after processing; that is, the second light processing unit 41 is a light diffusion unit. The second light processing unit 41 and the first light processing unit 40 can be integrally formed from the same material, or they can be independently formed from the same material and then assembled, such as integrally or separately formed from milky white PC. Of course, in other embodiments, different materials can be integrally or separately formed.

[0160] In one embodiment of this invention, the micro-optical structure on the second light processing unit 41 is disposed on the surface of the second light processing unit 41 away from the light source component 3. A third light processing unit 42 is disposed on the surface of the second light processing unit 41 facing the light-emitting element 3. The third light processing unit 42 corresponds to the second light processing unit 41 and is directly or indirectly attached to the second light processing unit 41. The third light processing unit 42 is a thin film with light diffusion function, which can diffuse the light emitted from the light source component 3, making the light transmitted through the third light processing unit 42 to the second light processing unit 41 more diffuse. The third light processing unit 42 can be made of polyester film, PET material, or other materials. In some embodiments, the third light processing unit 42 and the second light processing unit 41 are bonded together with transparent adhesive.

[0161] See Figure 16 , 17and 18, Figure 16 and 17 These are two implementations of the frame 5 in one embodiment of this utility model. Figure 18 This is a cross-sectional view and enlarged view of the frame 50 according to an embodiment of the present invention. Please refer to [link / reference]. Figure 16 In one embodiment of this utility model, the frame 5 includes a side frame 50 and an auxiliary support rod 52, wherein the number of side frames 50 is four, and two opposing side frames 50 are connected as one unit by the auxiliary support rod 52, and the two can be connected as follows: Figure 16 The parts shown are molded separately and then connected together, or they can be assembled as shown. Figure 17 The two opposing frame edges shown are integrally formed with the auxiliary support rod 52. A part of the optical component 4 is fixed by the auxiliary support rod 52. For example, in one embodiment of this utility model, the two long sides of the first light processing unit 40, the second light processing unit 41 and the third light processing unit 42 near the long side of the first light processing unit 40 are fixed with the auxiliary support rod 52, thereby improving the overall fixing strength of the optical component 4.

[0162] In one embodiment of this utility model, the optical component 4 is also fixed to the mounting part 12 by the frame 5. However, compared with the aforementioned frame 5, the connector 51 is eliminated. The fixation is achieved by the cooperation between the unique structure between the frame 50 and the mounting part 12. The two ends of the frame 50 are trapezoidal structures with an angle of 45° on the hypotenuse. The frames 50 are perpendicular to each other after the hypotenuses of the trapezoids cooperate with each other.

[0163] Please refer to Figure 18 and Figure 19 , Figure 18 This is a cross-sectional view of the frame along the horizontal direction in one embodiment of the present invention, and an enlarged view thereof. Figure 19 This is a schematic diagram of the combination of the frame 50 and the base 1 (mounting part 12) in one embodiment of the present invention, as shown below. Figure 18 The frame 50 includes a first step 53, a fixing groove 54, and a bearing surface 55, all three of which are integrally formed on the frame 50. Figure 19 As shown, the base 1 includes a mounting portion 12, which includes a limiting portion 122 away from the base plate 10, and a receiving portion 123 located around the limiting portion 122. At least a portion of the first step 53 and a fixing groove 54 are disposed on the receiving portion 123. Adhesive material can be disposed in the fixing groove 54 to fix it to the receiving portion 123. In some embodiments, the inner wall of the fixing groove 54 is provided with threads or protrusions. Screws or rivets penetrating the receiving portion 123 extend into the fixing groove 54 and engage with its threads or protrusions to fix the frame 5 and the base 1. The limiting portion 122 and the bearing surface 55 clamp and fix the optical component 4. Please refer to... Figure 20This is a schematic diagram of the micro-optical structure 410 in one embodiment of the present invention, enlarged to a certain scale for easier understanding. Figure 20 As shown, the micro-optical structure 410 is a patterned structure disposed on the surface of the second light processing unit 41 away from the light-emitting element 3, such as a triangular array pattern; of course, in other embodiments it can also be a circle, rectangle, etc., but is not limited thereto. Of course, it can also be a micro-protrusion array in the light-emitting direction. In some other embodiments, it can also be a grating array disposed on the second light processing unit 41. This micro-optical structure 410 makes the surface of the second optical processing unit 41 rough, and the light passing through the second light processing unit 41 is randomly emitted and reflected in various directions by the micro-optical structure 410. That is, the second optical processing unit 41 with a rough surface has inconsistent detection directions at different points on its surface. Even if the incident light is parallel or focused, the emitted or reflected light is also diffused in different directions. That is, its light-emitting surface has no obvious bright spots and dark spots, the light emission is uniform, and the glare is small.

[0164] See Figure 21 This is an exploded view of an LED lamp in another embodiment of the present invention. Compared with the aforementioned LED lamp with a second light processing unit 41, it does not have a third light processing unit 42. The second light processing unit 41 is an anti-glare bonding plate, the material of which is different from that of the first light processing unit 40, and it has the effects of scattering and uniform light.

[0165] In this embodiment, by combining the first light processing unit 40, the second light processing unit 41, and the third light processing unit 42, a UGR value of less than or equal to 19 can be achieved. The UGR value, or Uniform Glare Value, can be used to evaluate lighting quality. The calculation method for the Uniform Glare Value is as follows:

[0166]

[0167] Among them, L b Background brightness, in cd / m² 2 ω is the solid angle formed by the luminous part of each lamp with respect to the observer's eye, measured in sr; L α The luminance of the luminaire in cd / m² at the observer's eye direction. 2 P is the position index for each individual luminaire.

[0168] In this invention, the light intensity, the shape of the light-emitting surface, and the thickness of the lamp are controlled to regulate the light output. b , ω, L α P, thereby controlling the uniform glare value (UGR value) of the luminaire, ensuring the light output quality and user comfort of the luminaire. The solid angle is the projected area of ​​any object onto a unit sphere centered at the observation point (i.e., the human eye), which is the solid angle of the object relative to the observation point.

[0169] In some embodiments of this utility model, the light-emitting elements 31 (i.e., LED beads or LED chips of the light-emitting elements 31) provided in the light source assembly 3 of the LED lamp are of at least two types (or more). The light-emitting elements 31 can be composed of LED beads or LED chips, and multiple light-emitting elements 31 are arranged in an array on the circuit board 30 to form the light source assembly 3. In one embodiment of this utility model, the light-emitting elements 31 (i.e., LED beads or LED chips of the light-emitting elements 31) are of two types. For ease of description, one type of light-emitting element is referred to as light-emitting element 31a, and the other type as light-emitting element 31b. Light-emitting elements 31a and 31b are configured to have different color temperatures or different light emission intensities, or in other words, light-emitting elements 31a and 31b simultaneously have different color temperatures and light emission intensities. In one embodiment of this utility model, light-emitting elements with different color temperatures and / or different light intensities are arranged in a parallel manner, as follows: Figure 22 As shown, on the base plate 10 of the LED lamp, there are multiple rows of light-emitting element arrays arranged horizontally, each consisting of multiple light-emitting elements 31a and multiple light-emitting elements 31b. Figure 22 As shown, in the same row, all are composed of the same type of light-emitting body. For example, the first row is composed of multiple light-emitting bodies 31a, and the next row adjacent to the first row is composed of multiple light-emitting bodies 31b, and so on. That is, each row of light-emitting body array is composed of the same light-emitting body, but the types of light-emitting bodies in adjacent rows are different or at least two types.

[0170] Please see Figure 23 As shown, this is another embodiment of the light-emitting body arrangement of the present invention. As shown in the figure, multiple light-emitting bodies 31a and multiple light-emitting bodies 31b are respectively arranged longitudinally, forming multiple rows of light-emitting body arrays along the longitudinal direction. Each row of light-emitting body arrays consists of light-emitting bodies of the same type, but the types of light-emitting bodies in adjacent rows are different or at least two types. Figure 22 and 23 The LED lamps shown have arrays of different light-emitting elements spaced apart from each other. That is, if an array of light-emitting elements is composed of one type of light-emitting element, its adjacent row or column must be an array of light-emitting elements composed of another type of light-emitting element.

[0171] Of course, in other embodiments of this utility model, rows or columns composed of different light-emitting bodies can also be arranged in a cyclical manner with multiple rows or columns spaced apart.

[0172] Reference Figure 22 and Figure 23The embodiment shown can utilize an array of light-emitting elements of different types arranged in parallel or aligned rows, with intervals between them, to create unique light effects on its emitting surface. For example, the brightness of certain areas may be higher or lower than that of certain other areas, forming a light-emitting pattern. Please refer to the following... Figure 24 Light overlap regions 310 are formed between light emitters 31a and 31b, and light overlap regions 311 are formed between light emitters 31a and 31b, arranged in a 2*2 pattern. Each column contains two light emitters 31a and two light emitters 31b, with a light overlap region 312 at its center. Light overlap regions 313 are formed between light emitters 31b and 31b. Due to the differences between adjacent light emitters, the light intensity or color temperature of the light overlap regions 310, 311, 312, and 313 varies. The light intensity and color temperature of the light overlap regions can be controlled by setting different adjacent light emitters, thereby forming a specific patterned light emission on the overall light-emitting surface. Figure 24 As shown, the light emission effect varies when viewed in each row or column, resulting in a specific patterned light emission.

[0173] Please see Figure 25 This is another arrangement of multiple light-emitting elements in one embodiment of the present invention. For example... Figure 24 As shown, the LED lamp is equipped with two types of light emitters, namely light emitter 31a and light emitter 31b. Light emitters 31a and light emitter 31b have different color temperatures and / or light emission intensities. Light emitters 31a and light emitter 31b are arranged alternately, that is, the light emitter adjacent to light emitter 31a must be a different light emitter 31b. In other words, light emitters 31a and light emitter 31b are arranged adjacent to each other in each row or column. Overall, light emitters 31a and light emitter 31b are mutually doped and uniformly doped on the base plate 10.

[0174] Please see Figure 26 ,and Figure 27 ,for Figure 25 The embodiments described in the diagram are illustrated from another perspective, such as... Figure 26 and 27 As shown, in the horizontal row direction or the vertical column direction, the light emitters 31a and 31b are distributed in a wavy curve, or in a form close to a cosine (sine) function graph, or in an S-shaped cyclic distribution. This distribution of light emitters makes the light intensity and / or color temperature of the light overlap area between each adjacent light emitter basically the same.

[0175] Please see Figure 28The figure shows a schematic diagram of the light overlap area in one embodiment of the present invention. As shown in the figure, since the light emitters 31a and 31b are arranged alternately when the light emitters are set, the light overlap area only has light overlap area 311 and light overlap area 312. Moreover, the light overlap area 311 and light overlap area 312 are evenly distributed, so that the overall light output of the LED lamp is uniform and there are no obvious bright spots or dark spots.

[0176] Continue reading Figure 28 In one embodiment of this utility model, in the longitudinal or column direction, the longitudinal distance between adjacent different light-emitting bodies 31a and 31b is L1, 10mm≤L1≤30mm;

[0177] In the longitudinal or column direction, the longitudinal spacing between adjacent identical light-emitting bodies 31a and 31b (light-emitting bodies 31b and 31b) is L2, 20mm≤L2≤40mm;

[0178] In the horizontal or row direction, the horizontal distance between adjacent light-emitting bodies 31a and 31b is L3, 10mm≤L3≤30mm;

[0179] In the horizontal or row direction, the longitudinal spacing between adjacent identical light-emitting bodies 31a and 31b (light-emitting bodies 31b and 31b) is L4, 30mm≤L4≤80mm;

[0180] Setting the distances of L1, L2, L3, and L4 can prevent the light overlap area between the light emitters from being too large, which would significantly affect the uniformity of light output.

[0181] In another embodiment of this utility model, the optical component is directly disposed on the mounting part and fixed by an adhesive. The optical component is unobstructed in the light emission direction of the LED lamp, forming a complete and continuous light emission surface, which makes the LED lamp have better light emission effect and appearance.

[0182] Please see Figure 29 and Figure 30 , Figure 29 This is a three-dimensional structural diagram of an LED lamp in one embodiment of the present invention. Figure 30 This is an exploded front view of an LED lamp fixture according to one embodiment of the present invention, as shown below. Figure 29 As shown, the LED lamp 1000 includes a base 1, a power supply 2, and a light source assembly 3. Figure 29 (Not shown), optical component 4 and suspension mechanism 6, wherein the power supply device 2, light source assembly 3, optical component 4 and suspension mechanism 6 are all fixed to the base 1. Figure 30As shown, the base 1 includes a base plate 10 and side walls 11 arranged around the base plate 10 (or periphery). The base plate 10 and the side walls 11 form a receiving groove 14. The light source assembly 3 is disposed in the receiving groove 14 formed by the base plate 10 and the side walls 11. More specifically, the light source assembly 3 is fixed on the base plate 10.

[0183] In one embodiment of this utility model, the base plate 10 and the side wall 11 are an integral structure. For example, the base 1 is made of metal, such as iron or aluminum, and the base plate 10 and side wall 11 can be integrally formed by stamping or bending. Alternatively, the base 1 can be made of plastic and the base plate 10 and side wall 11 can be integrally formed by injection molding, hot pressing, etc. The base plate 10 and side wall 11 are formed from the same material.

[0184] In one embodiment of this utility model, the base plate 10 and the side wall 11 are separate structures. After the base plate 10 and the side wall 11 are formed independently, the base plate 10 and the side wall 11 are assembled to form the base 1. The base plate 10 and the side wall 11 can be made of the same material or different materials.

[0185] Combination Figure 29 and Figure 30 As shown, in one embodiment of the present invention, an LED lamp is disclosed. The LED lamp 1000 includes a base 1 that forms the main frame of the lamp. The base 1 includes a bottom plate 10 that is basically horizontal when installed, that is, the bottom plate 10 is attached to the mounting surface and is roughly parallel to the mounting surface. It also includes a side wall 11 that surrounds the bottom plate 10 (or is set around the perimeter, forms a certain angle with the bottom plate 10, and extends to one side of the bottom plate 10). The side wall 11 has a certain height relative to the bottom plate 10 and forms a receiving groove 14 (or receiving space 14) with the bottom plate 10. The receiving groove 14 is used to arrange other components of the LED lamp 1000. For example, in one embodiment of the present invention, a light source assembly 3 is provided in the receiving groove 14. The light source assembly 3 is attached to the bottom plate 10 and is completely contained in the receiving groove 14. That is, after the light source assembly 3 is attached to the bottom plate 10, its height is less than or equal to the height of the side wall 11.

[0186] In some other embodiments of the present invention, the light source assembly 3 is at least partially housed within the receiving groove 14.

[0187] For ease of description, the side of the base plate 10 facing the receiving groove 14 is called the front side of the base plate 10, and the other opposite side, that is, the side of the base plate 10 away from the receiving groove 14, is called the back side of the base plate 10; the side of the side wall 11 facing the receiving groove 14 is called the inner surface of the side wall 11, and the other opposite side, that is, the side of the side wall 11 away from the receiving groove 14, is called the outer surface of the side wall 11.

[0188] The LED lamp 1000 also includes a power supply device 2, which is fixed to the base 1 and electrically connected to the light source assembly 3, for supplying power to the light source assembly 3 and other electrical components of the LED lamp 1.

[0189] In one embodiment of the present invention, the power supply device 2 is disposed on the side wall 11, or more specifically on the outer surface of the side wall 11.

[0190] Of course, in some other embodiments of this utility model, the power supply device 2 may also be disposed in the receiving groove 14, for example, the power supply device 2 may be disposed on the inner surface of the side wall 11 or the front of the bottom plate 10.

[0191] An optical component 4 is provided at the end of the receiving groove 14 away from the base plate 10, that is, in the light emission path of the light source assembly 3. The optical component 4 covers the receiving groove 14 and forms a relatively sealed space with it, which can protect the light source assembly 3 installed in the receiving groove 14 to a certain extent. The projection of the optical component 4 on the base plate 10 completely covers the light source assembly 3, and after light processing, the light emitted by the light source assembly 3 is finally projected outside the LED lamp 1000.

[0192] Please see Figure 31 and Figure 32 ,in Figure 31 This is a schematic diagram of the back of an LED lamp according to one embodiment of the present invention. Figure 32 This is an exploded view of the back of an LED lamp according to one embodiment of the present invention.

[0193] like Figure 31 As shown, a reinforcing structure 100 is provided on the base plate 10. There is at least one reinforcing structure 100, and the reinforcing structures 100 are perpendicular to each other. In one embodiment of this utility model, the reinforcing structure 100 protrudes from the back of the base plate 10 and is recessed from the front. The light source assembly 3 or some other components can be disposed in the recess formed by the reinforcing structure 100 in the base plate 10, thereby achieving space reuse to a certain extent and reducing, for example, the height of the light source assembly 3. Furthermore, since the light source assembly 3 needs to maintain a certain distance from the optical component 4 to meet light emission effects such as glare and light uniformity, placing the light source assembly 3 in the recess formed by the reinforcing structure 100 can reduce the overall height of the LED lamp.

[0194] In one embodiment of this utility model, the reinforcing structure 100 and the base plate 10 are integrally formed. For example, when the base plate 10 is made of metal, the reinforcing structure 100 is integrally formed by stamping the base plate 10. The reinforcing structure 100 is not directly formed relative to the base plate 10 by adding other materials, so it will not cause the base plate to rise. The reinforcing structure 100 has a certain height relative to the base plate 10. That is, the setting of the reinforcing structure 100 makes the base plate 10 no longer a flat surface. It also increases a certain thickness in the direction perpendicular to the base plate 10, which improves the ability of the base plate 10 to resist shear force and lateral pressure. Without adding extra materials, the structural strength of the base plate 10 is enhanced through surface design.

[0195] Of course, in another embodiment of this utility model, the reinforcing structure 100 and the base plate 10 are separate structures. That is, after the base plate 10 is formed independently, the reinforcing structure 100 is additionally provided on the front or back of the base plate 10. For example, the reinforcing structure 100 is fixed on the base plate 10 by means of adhesive or welding.

[0196] In some other embodiments of this utility model, the reinforcing structure 100 may also be arc-shaped, ring-shaped, zigzag-shaped, wavy, etc., but is not limited to these. The shape of the reinforcing structure 100 can be designed according to the light output requirements, and the shape of the light source component 3 can be further changed.

[0197] like Figure 31 As shown, a mounting portion 12 is provided on the end of the side wall 11 away from the base plate 10. The mounting portion 12 is arranged around the side wall 11, approximately parallel to the base plate 10, and extends a certain distance towards the outer surface of the side wall 11. It is used to mount the optical component 4, that is, the optical component 4 is mounted on the side of the mounting portion 12 facing away from the base plate 10. At least one suspension mechanism 6 is provided on the side of the mounting portion 12 facing the base plate 10. The suspension mechanism 6 can be fixed to the mounting portion 12 by means of screws, adhesives, welding, clips, etc., and the suspension mechanism 6 is then fixed to the mounting surface, such as the ceiling, wall, suspension structure, etc., thereby realizing the fixation of the LED lamp.

[0198] In one embodiment of this utility model, the number of suspension mechanisms 6 is an even number, such as 2 or 4.

[0199] In another embodiment of this utility model, the number of suspension mechanisms 6 is an odd number, such as 1, 3, 5, etc.

[0200] In one embodiment of this utility model, the mounting part 12 and the side wall 11 are integrally formed, that is, the side wall 11 and the mounting part 12 are integrally formed by stamping a substrate forming the base 1, such as a flat metal surface. Of course, the side wall 11 can also be formed by bending. When the substrate forming the base 1 is made of plastic, the side wall 11 and the mounting part 12 can also be formed by hot pressing or injection molding.

[0201] As shown in Figure 32 is an exploded back view of the LED lamp 1000 in an embodiment of the present utility model, wherein the suspension mechanism 6 is fixed to the mounting portion 12 by means of screws, at least one mounting hole is provided on the mounting portion 12, and locking holes corresponding to the mounting holes are provided on the suspension mechanism 6. During installation, the locking holes of the suspension mechanism 6 correspond to the mounting holes on the mounting portion 12 one by one, and locking members (such as screws, rivets, etc.) pass through the locking holes and the mounting holes, so that the suspension mechanism 6 is fixed to the mounting portion 12.

[0202] Please refer to Figure 33 , wherein Figure 33 is an enlarged view of position F Figure 32 in an embodiment of the present utility model. As shown in Figure 33 , the suspension mechanism 6 includes a connecting portion 61, and the connecting portion 61 fits against the surface of the mounting portion 12 facing the base plate 10 when the suspension mechanism 6 is fixed to the mounting portion 12. At least one locking hole 62 is provided on the connecting portion 61, and the locking hole 62 is a through hole. A locking reinforcement portion 63 and a hook 64 extend from the side edge of the connecting portion 61, wherein a locking reinforcement hole 631 is provided on the locking reinforcement portion 63.

[0203] In one embodiment, the locking reinforcement hole 631 can be locked to the side wall 11 by screws, for reinforcing the connection between the suspension mechanism 6 and the base 1.

[0204] In one embodiment, the locking reinforcement hole 631 can serve as a fixing hole for a suspension structure, for example, a suspension chain passes through the locking reinforcement hole 631 to realize the installation and fixing of the LED lamp.

[0205] The hook 64 comprises a first arm portion 641, a second arm portion 642, a third arm portion 643 and a fourth arm portion 644 extending from the connecting portion 61. The first arm portion 641 and the third arm portion 643 are parallel to each other and substantially perpendicular to the mounting portion 12 and the connecting portion 61; the second arm portion 642 and the fourth arm portion 644 are parallel to each other and arranged substantially parallel to the mounting portion 12 and the connecting portion 61. The connecting portion 61, the first arm portion 641, the second arm portion 642, the third arm portion 643, and the fourth arm portion 644 together form a structure similar to the Chinese character "wei (guard)" and are substantially in the same plane, so that the suspension mechanism 6 presents a semi-enclosed structure and is not easy to fall off after being fixed.

[0206] Please refer to Figure 34 and Figure 35 , which are schematic diagrams of other implementations of the suspension mechanism 6 in some other embodiments of the present utility model. As shown in Figure 34 , the suspension mechanism 6 omits the fourth arm portion 644 compared to the foregoing suspension mechanism, and the hook 64 portion of the suspension mechanism 6 comprises the first arm portion 641, the second arm portion 642 and the third arm portion 643.

[0207] like Figure 35 The suspension mechanism 6 shown is an embodiment of this utility model. The suspension mechanism 6 includes a connecting part 61, which fits against the side of the mounting part 12 facing the base plate 10 when the suspension mechanism 6 is fixed to the mounting part 12. The connecting part 61 is provided with at least one locking hole 62, which is a through hole. A locking reinforcement part 63 and a hook 64 are provided extending from the side of the connecting part 61, wherein the locking reinforcement part 63 is provided with a locking reinforcement hole 631. The hook 64 has a first arm 641, a second arm 642, a third arm 643, and a fourth arm 644 extending to the connecting part 61, wherein the first arm 641 and the second arm 642 are located in the same plane, the third arm 643 and the third arm 644 are located in the same plane, and the planes containing the first arm 641 and the second arm 642 and the planes containing the third arm 643 and the fourth arm 644 are substantially perpendicular.

[0208] Please see Figure 36 This is one embodiment of the present utility model. Figure 32 As shown in the enlarged view at point G in the figure, the mounting part 12 is provided with at least one mounting hole 124, which is a through hole, meaning it completely penetrates the mounting part 12. The locking hole 62 on the connecting part 61 of the suspension mechanism 6 corresponds to the mounting hole 124, and the two are positioned to each other and connected and fixed by screws or rivets.

[0209] In one embodiment of this utility model, each suspension mechanism 6 is provided with two locking holes 62, and the number of mounting holes 124 provided on the mounting part 12 corresponding to the position of each suspension mechanism 6 is also two, and the number of locking holes 62 and mounting holes 124 correspond one-to-one.

[0210] In one embodiment of this utility model, the number of locking holes 62 is greater than the number of mounting holes 124.

[0211] In one embodiment of this utility model, the number of locking holes 62 is less than the number of mounting holes 124.

[0212] In one embodiment of this utility model, the mounting holes 124 are distributed in a straight line along the mounting portion 12 to facilitate the positioning and fixing of the locking holes 62 and the mounting holes 124.

[0213] In one embodiment of this utility model, the mounting holes 124 are distributed in a scattered manner along the mounting portion 12, so that when the LED lamp is fixed to the mounting surface (such as the ceiling, wall, etc.), the force on the mounting portion 12 is more uniform, reducing the risk of deformation or damage.

[0214] Please see Figures 37-38 ,in Figure 37 for Figure 29A schematic diagram of the LED luminaire along section III-III; Figure 38 In one embodiment of this utility model, Figure 37 A magnified view of a portion of point H in the image; Figure 39 In one embodiment of this utility model, Figure 30 A magnified view of point E in the image. (Reference) Figure 37 The base 1 has a receiving groove 14 formed by a base plate 10 and a side wall 11. The light source assembly 3 is housed in the receiving groove 14, or more specifically, it is disposed on the base plate 10 and is directly attached to the base plate 10 or indirectly attached through a medium. The optical component 4 is disposed in the light emission direction of the light source assembly 3 and at least partially or completely covers the light source assembly 3. At the same time, the optical component 4 is combined with the mounting part 12 at the end of the side wall 11 away from the base plate 10, so that the receiving groove 14 becomes a relatively sealed space. The light source assembly disposed in the receiving groove 14 can be protected by the base 1 and the optical component 4. That is, the base 1 and the optical component 4 isolate the light source assembly 3 from the external environment, avoiding most of the influence or damage of the external environment on the light source assembly 3.

[0215] In one embodiment of this utility model, the power supply device 2 is disposed on the outer side of the side wall 11, that is, on the outer side relative to the accommodating space. The power supply device 2 includes a power supply box 20 disposed externally and circuit components 21 and other related electronic components housed inside the power supply box 20. Figure 9 Not shown, please refer to Figure 32 The power supply box 20 shares a side wall 11, meaning that the power supply box 20 and the side wall 11 together form a power supply cavity for accommodating the circuit assembly 21 and other related electronic components. By reusing the side wall 11, the overall cost and weight of the lamp are reduced, while the volume is also reduced. The power supply device 2 is located in the empty space outside the receiving groove 14 relative to the side wall 11 and the mounting part 12. Utilizing this empty space to house the power supply device 2 avoids increasing the overall height and volume of the lamp.

[0216] Please see Figure 38 and Figure 39 ,like Figure 38 As shown, Figure 38 for Figure 37 The enlarged view at point H shows that the power supply box 20, the side wall 11, and the mounting portion 12 of the side wall 11 together form the power supply cavity. At least one adhesive-containing groove 125 is provided on the mounting portion 12. The adhesive-containing groove 125 is arranged along the length of the mounting portion 12 and surrounds the outer edge of the LED lamp. The tops of both sides of the adhesive-containing groove 125 contact the optical component 4, indicating that the height of the adhesive it can hold can at least reach the height of the optical component 4 and contact the optical component 4. After the adhesive cures, it can effectively fix the optical component 4.

[0217] refer to Figure 38 and Figure 39 An overflow groove 126 is provided between the mounting part 12 and the optical component 4. The height and depth of the overflow groove 126 are similar to those of the adhesive container 125, which can be used to contain the adhesive overflowing from the adhesive container 125, preventing the adhesive from contaminating other areas of the lamp. At the same time, the depth of the overflow groove 126 is at least greater than the height of the screws (or rivets, etc.) used to fix the suspension mechanism 6, thereby preventing the screw structure of fixing the suspension mechanism 6 from damaging the integrity of the light-emitting surface (or light-emitting cover). Specifically, the outer side of the mounting part 12 has a bending portion limiting frame 127, which is set along the light-emitting direction of the LED lamp. Its highest position is higher than the highest position of the adhesive container 125, forming a mounting step. That is, the optical component 4 is stacked at the highest point of the adhesive container 125, and the outermost edge of the optical component 4 is blocked by the bending portion limiting frame 127, thereby forming a sealed package and preventing the optical component 4 from shifting.

[0218] In one embodiment of this utility model, the height of the bending portion limiting frame 127 is equal to the thickness of the optical component 4, and the two fit together, so that the surface of the LED lamp in the light-emitting direction is intact.

[0219] In one embodiment of this utility model, the height of the bending portion limiting frame 127 is less than the thickness of the optical component 4, and the surface of the LED lamp in the light-emitting direction is the optical component 4, thereby reducing the color difference on the surface in the light-emitting direction.

[0220] In one embodiment of this utility model, the height of the bending portion limiting frame 127 is greater than the thickness of the optical component 4, further preventing light leakage from the LED lamp in the lateral direction.

[0221] In one embodiment of this utility model, the width of the overflow groove 126 is greater than the width of the glue receiving groove 125.

[0222] In some other embodiments of this utility model, the width of the overflow groove 126 may be less than or equal to the width of the glue receiving groove 125.

[0223] In this embodiment, the optical component 4 is fixed by setting the adhesive groove 125, together with the bending part limiting frame 127 and adhesive, so that there are no other obstructions in the light output direction of the LED lamp. The LED lamp has a complete and unobstructed light output surface with small or no color difference, making the LED lamp more beautiful.

[0224] Please see Figure 40 , Figure 40 This is an exploded view of an LED lamp in another embodiment of the present invention, wherein the optical component 4 includes a light-emitting area 400 and a covering area 401, and other components are the same as described above.

The coating area 401 is provided with a screen printing structure to enhance the strength of the coating area and reduce the color difference between the coating area 401 and the light-emitting area 400.

[0226] In one embodiment of this utility model, the bonding area 401 and the light-emitting area 400 are integrally formed from different materials, and the requirements for strength, light emission and color difference are met simultaneously by combining different materials.

[0227] In one embodiment of this utility model, the covering area 401 and the light-emitting area 400 are independently formed from the same material and then assembled.

[0228] In one embodiment of this utility model, the covering area 401 and the light-emitting area 400 are formed independently from different materials and then assembled.

[0229] In one embodiment of this utility model, the surface of the bonding area 401 that is bonded to the mounting part 12 may be provided with a microstructure array, such as a microstructure array of protrusions or depressions, to increase the surface roughness and surface area of ​​the bonding area 401, increase the bonding area with the adhesive, and increase the fixing strength between the bonding area 401 and the mounting part 12. That is, the bonding area 401 and the light-emitting area 400 may be provided with different roughness or surface microstructures to meet different functional requirements.

[0230] Please see Figure 40 or Figure 30 or Figure 37 In this utility model, there are multiple light source components 3, or at least one, and the light source components 3 are arranged in parallel with equal intervals between them.

[0231] Please see Figure 41 This is a partial disassembly diagram of the light source assembly 3 in one embodiment of the present invention. The light source assembly 3 includes a circuit board 30, on which at least one light-emitting element 31 is disposed. The light-emitting element 31 is composed of an LED chip 314 and an LED chip light processing element 315. The LED chip light processing element 315 may be a lens with a specific surface shape made of resin, glass, plastic, etc. The light processing unit 315 covers the LED chip 314 on the circuit board 30.

[0236] refer to Figure 42 This is a simplified schematic diagram of a power supply device 2 according to an embodiment of the present invention. The power supply device 2 includes a power supply box 20 and a circuit assembly 21 disposed in the power supply box 20. On the side of the power supply box 20 that contacts the mounting portion 12, a power supply box fixing piece 200 parallel to the mounting portion 12 is provided. The power supply box fixing piece 200 has locking holes, which can be used to fix the power supply box 20 to the mounting portion using screws or rivets. An inclined mounting portion 201 is provided on the side of the power supply box 20 near the side wall 11. The inclined mounting portion 201 has mounting holes, which can be fixed to the inclined portion of the side wall 11 relative to the base plate 10. That is, the inclined mounting portion 201 fits against the side wall 11 during installation and is parallel to the side wall 11. End caps 202 are provided at both ends of the power supply box 20 along its length. The end caps 202 can be integrally formed with the power supply box 20, or they can be formed independently and then assembled onto the power supply box 20.

[0237] In another embodiment of this utility model, the power supply box 20 can also be fixed to the base 1 by means of adhesive, welding or snap-fit.

[0238] The power supply unit 2 contains a circuit board and various electronic components, which can realize the dimming and color-adjusting functions of the LED lamp 1000. That is, the light-emitting body 31 in this utility model can be composed of only one color temperature and color of LED beads, or it can be composed of at least two color temperatures and colors of LED beads. The combination of LED beads with different color temperatures and colors realizes the dimming and color-adjusting functions of the LED lamp 1000.

[0239] In one embodiment of this utility model, two light emitters 31 of different colors and color temperatures are arranged alternately on the same circuit board, and the current of the two types of lamp beads is controlled respectively to change the working state of the two types of lamp beads to realize the dimming and color adjustment of LED lamps.

[0240] In one embodiment of this utility model, at least two types of light emitters 31 with different colors and color temperatures are arranged at intervals on the same circuit board, and the working state of at least one of the light beads is controlled separately or simultaneously to realize the dimming and color adjustment functions of the LED lamp.

[0241] In one embodiment of this utility model, at least two circuit boards 30 are respectively provided with different types of LED beads, and the LED beads on a single lamp board are of the same type. That is, the light source component 3 achieves different light intensity, color temperature, color and other functions through the configuration of different LED beads, and further realizes the dimming and color adjustment of LED lamps.

[0242] Color adjustment can be performed using buttons and / or knobs on the wall; for example, pressing a button changes the color, and rotating a knob changes the brightness. A remote control can also be used, with buttons on the remote enabling dimming and color adjustment. Alternatively, a mobile application (APP) can be used, offering various control effects such as timed on / off switching, displaying different colors over time to simulate sunlight, and adjusting dimming and color to music. Alternatively, an adjustment switch, such as a knob or dial, can be installed on the power supply unit 2 to adjust to different levels for dimming and color adjustment.

[0243] In one embodiment of this utility model, the LED light fixture can be installed inside the ceiling of a house. Because it is rectangular, during installation, one section of the ceiling is first removed to create an empty space, and then the LED light fixture is placed into that space. Figure 31 and Figure 32 As can be seen, the side of the LED light fixture is trapezoidal, which facilitates the smaller end entering the ceiling during installation, forming a recessed installation. This installation method allows for virtually no gap between the LED light fixture and the ceiling. If better sealing is required, a soft sealing layer can be applied to the side of the mounting part 12 facing the ceiling.

[0244] As mentioned earlier, LED lights are installed in the empty spaces of the suspended ceiling. Specifically, as follows... Figure 43 As shown, Figure 43 One embodiment is a schematic diagram of a light fixture installed in a suspended ceiling, wherein one section of the suspended ceiling 60 is removed to form a ceiling cavity 600 for installing an LED light fixture 1. Multiple horizontally extending mounting rods 601 are provided at the edge of the ceiling cavity 600, and a suspension mechanism 6, more precisely, a hook 64, is partially fixed to the mounting rods 601 to secure the LED light fixture.

[0245] In one embodiment of this utility model, the above-mentioned LED lamp is different from the traditional wire wiring method. It uses wiring element 7 to realize the conduction of at least some electronic components in the LED lamp, thereby simplifying the internal wiring of the LED lamp.

[0246] like Figure 44As shown in the figure, it is a schematic partial exploded structural view of an LED lamp according to an embodiment of the present invention. A light source assembly 3 is disposed on a base plate 10, and the light source assembly 3 achieves electrical connection with a power supply device 2 (not shown in the figure) via a wiring element 7. The wiring element 7 may be a conducting wire with certain hardness and plasticity, for example, a single-strand tinned copper wire. As shown in Figure 45, it is Figure 44 a partially enlarged view of I in the figure. A circuit board 30 is provided with a plurality of pads 33, the number of the wiring elements 7 matches the number of the pads 33, and the wiring elements 7 achieve fixed connection with the pads 33 through solder paste 8 heated and melted. The wiring element 7 is stamped with a turning portion 71 by means of a simple jig, so as to achieve an insulating effect that the wiring element 7 does not contact the base plate 10. Before the solder paste 8 is heated and welded, it is arranged in upper and lower parts on the pad 33, which is approximately similar to the Chinese character "Ri", with a gap in the middle, and the wiring element 7 is located in the gap and contacts the pad 33.

[0247] a communication portion 113 is clamped into a wiring port 112 on a side wall 11, and the wiring element 7 connected to the light source assembly 3 is electrically connected to the power supply device 2 through the communication portion 113, that is, the wiring element 7 penetrates into the communication portion 113. As shown in Figure 46 , it is a schematic partial exploded structural view of an LED lamp according to an embodiment of the present invention, wherein the enlarged view of part J is shown by Figure 47 . The communication portion 113 includes a hollow portion 1131 and a conductive portion 1132. The wiring element 7 enters from the hollow portion 1131 side and connects to the communication portion 113, and the conductive portion 1132 contacts the power supply device 2.

[0248] As shown in Figure 48 , the power supply device 2 has a clamping portion 210 and a power board 22, wherein one end of the clamping portion 210 is fixed on the power board 22, the other end is provided with a first clamping portion 211, a side close to the power board 22 is provided with a third clamping portion 213, and a second clamping portion 212 is disposed between the first clamping portion 211 and the third clamping portion 213. In this embodiment, when the power supply device 2 is disposed outside the concave cavity 14, the conductive portion 1132 is connected to the clamping portion 210, wherein the end of the first clamping portion 211 away from the second clamping portion 212 is wider than the diameter of the conductive portion 1132, which facilitates the conductive portion 1132 to be clamped into the first clamping portion 211. The width of the part of the first clamping portion 211 away from the second clamping portion 212 gradually decreases along the direction toward the second clamping portion 212 to be slightly smaller than the diameter of the conductive portion 1132, which facilitates limiting the position of the conductive portion 1132. The size of the second clamping portion 212 matches the conductive portion 1132, and the connection position between the second clamping portion 212 and the third clamping portion 213 is also slightly smaller than the diameter of the conductive portion 1132 for limiting the position of the conductive portion 1132. The width of the third clamping portion 213 is smaller than the diameter of the conductive portion. In this embodiment, the clamping portion 210 may be a copper elastic sheet.

[0249] The specific connection process between the power supply device 2 and the connecting part 113 is as follows: the conductive part first snaps into the first snap-fit ​​part, and then slides into the second snap-fit ​​part along its connection position with the second snap-fit ​​part. Since the size of the second snap-fit ​​part is adapted to the conductive part, and the third snap-fit ​​part is smaller than the diameter of the conductive part, the conductive part can be connected to the second snap-fit ​​part, thereby realizing the electrical connection between the power supply device and the light-emitting component. The number of snap-fit ​​parts matches the number of conductive parts.

[0250] The assembly method of the LED lamp includes the following steps: providing a connecting part, a light-emitting component, a wiring element, a base, and a power supply device; firstly, inserting the wiring element into the connecting part from the conductive part side, and extending the wiring element to a length sufficient to connect the light source component before cutting it off; the wiring element connected to the connecting part is stamped into a toothed shape with a bent portion using a simple jig. This method avoids the previous need for wire stripping, and allows for continuous feeding of large rolls, reducing downtime for material changes and shortening material change time; solder paste is applied to the soldering area of ​​the light-emitting component; when there are multiple light-emitting components, the stamped wiring element is placed on the light-emitting component. At the solder joints formed by solder paste in the soldering area, no separate solder wire is needed. Because the wiring components have bends, they can be insulated from the ground plane. Multiple solder joints can be soldered simultaneously by a machine, significantly improving production efficiency. This machine can be a galvanometer-type laser soldering machine. The soldered wiring components and light-emitting components are then fixed to the recessed cavity of the base. Fixing methods include glue, soldering, screws, and clips. The connecting part to the wiring components is installed on the side wall of the LED lamp. Finally, the snap-fit ​​part of the power supply is connected to the connecting part, thus achieving electrical connection between the power supply and the light-emitting components. This method enables fully automated mass production, reducing production costs while achieving excellent finished product results.

[0251] In summary, the LED lamps and their assembly and packaging methods disclosed in this utility model (1) set up a frame that is fixed by inserting a frame, so that the optical components can be fixed on the mounting part without additional fasteners, which simplifies the assembly and reduces the product defect rate and process complexity caused by using fasteners; (2) add a folding part to the base of the lamp to fix the optical components by folding the folding part, which eliminates the use of the frame, saves materials, and further improves production efficiency and reduces costs; (3) set the side wall of the base to have at least two inclined parts to increase the width of the power supply device configuration space provided by the side wall, which greatly reduces the requirement for the width of the mounting part, can achieve an extremely narrow blocking area, greatly improve the light output ratio and light output effect, and also increase the aesthetics of the lamps; (4) set the power supply device to protrude from the base plate to form a height difference with the base plate, so that when the two LED lamps are placed with the base plates attached, there is an overlapping area in the vertical direction. In this way, the base plates of the two LED lamps can be attached for packaging and transportation, which reduces the height space required for packaging and transportation and greatly saves packaging and transportation costs. (5) Set the intervals or staggers of LED beads with different color temperatures to achieve uniform light output without obvious bright spots.
