Description

An LED lamp Technical Field

[0001] The present invention relates to the field of lighting technology, and in particular to an LED lamp. Background Art

[0002] LED lamps are widely used in various places due to their easy installation and maintenance, energy saving, high brightness and small size. Their core component, the Light-Emitting Diode (LED), is a new generation of solid-state energy with the advantages of long life, high efficiency and energy saving, and green environmental protection.

[0003] Existing LED high-bay lights generally consist of a lamp body and an LED light source. The main difference between LED high-bay lights and household LED lights is that they have much higher power. High-bay lights typically have a power range of 50W to 200W, while ordinary household LED lights typically have a power of no more than 20W. Their structures also differ significantly. High-bay lights are generally required to have excellent heat dissipation and light output performance.

[0004] Existing LED lamps generally include a lamp body and an HID light source. The heat sink of the HID light source is usually formed by aluminum die-casting. However, aluminum die-casting can lead to problems such as large size and weight of the heat sink, and uneven heat sink thickness.

[0005] The heat sink is used to quickly dissipate the heat generated by the LED lamp during operation to prevent heat accumulation inside the LED lamp and affect normal operation. However, the heat sink generally increases or occupies the volume of the lamp, which has a certain impact on the packaging and transportation of the lamp.

[0006] In the existing design of LED lamps, the light output direction can only be fixed at a certain angle. When the environment changes (for example, the installation height or installation angle changes to a certain extent), the original LED lamps cannot or cannot fully meet the current installation environment, and the adaptability of LED lamps cannot meet customer needs.

[0007] In summary, in view of the shortcomings and defects of LED lamps in the prior art, how to design LED lamps to improve material utilization and reduce the weight of LED lamps is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0008] The present invention provides an LED lamp that is lighter, has better heat dissipation, is easier to assemble, and has a smaller size than the prior art. Other objects, effects, and beneficial effects of the present invention can be derived from the specific embodiments.

[0086] To facilitate understanding of the present invention, the present invention will be described in more detail below with reference to the relevant drawings. Preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described below. On the contrary, the purpose of providing these embodiments is to enable a more thorough and comprehensive understanding of the disclosure of the present invention. The following references to directions such as "axial direction", "above", "below", etc. are intended to more clearly illustrate the structural position relationship and are not limitations on the present invention. In the present invention, the definition of "vertical", "horizontal", and "parallel" is: including situations within ±10% of the standard definition. For example, vertical usually refers to an angle of 90 degrees relative to the reference line, but in the present invention, vertical refers to situations within 80 to 100 degrees.

[0087] The following describes an embodiment of the present invention with reference to the accompanying drawings. Figures 1A and 1B are exploded views of the main components of an LED lamp according to an embodiment of the present invention. Figure 1A is a top-down view, while Figure 1B is a bottom-up view. As shown in Figures 1A and 1B, the LED lamp 100 according to an embodiment of the present invention, from top to bottom (top and bottom refer to the perspectives in the figures, and the same applies below), primarily comprises a base 1, a light source 2, a lampshade 3, a power supply 4, an insulating box 5, and a housing 6. Furthermore, a protective coil 7 is provided on the base 1.

[0088] The light source part 2 is arranged on the base 1. The light source part 2 is mainly one or more LED light strips 21. The LED light strip 21 is provided with a plurality of LED light-emitting bodies 211. The LED light-emitting bodies 211 can be LED lamp beads, or other packaging structures with LED chips. The LED light strip 21 can be annular or roughly annular. The ring formed by multiple LED light strips 21 can be a concentric ring. The ring of the LED light strip 21 can include one or more disconnections, that is, the LED light strip 21 can also be arc-shaped or roughly arc-shaped. Multiple arc-shaped LED light strips 21 can form a ring. The disconnection position of the LED light strips 21 on the multiple rings can be at the same radius of the concentric rings, so that the LED light strips 21 on different rings can be electrically connected at the disconnection point.

[0089] On the base 1, the LED light strips 21 in different circular rings can have the same arc but different arc lengths. In other words, the lengths of the LED light strips 21 in different circular rings can be different. Specifically, the length of the LED light strips 21 in the circular ring near the center of the LED lamp can be shorter than the length of the LED light strips 21 in the circular ring near the edge of the LED lamp. Alternatively, the length of the LED light strips 21 in the inner circular ring can be shorter than the length of the LED light strips 21 in the outer circular ring. The disconnected design of the LED light strips 21 can reduce manufacturing costs.

[0090] In one embodiment, as shown in the figure, there are 12 arc-shaped LED light strips, which form three concentric rings, and each of these rings is broken at four locations.

[0091] In a specific embodiment, the base 1 is in the shape of a basin. The figure shows a case where a circular bottom plate 15 is used, that is, the base 1 includes a bottom plate 15 and a side wall 14 arranged around the bottom plate 15. The side wall 14 forms an accommodating space around the bottom plate 15, and the light source part 2 is arranged in the accommodating space. The base 1 can be stamped and formed in one piece using a metal plate, such as an aluminum plate. When the LED light strip 21 is directly attached to the base 1, the use of a metal plate can have good heat dissipation performance, and the one-piece structure helps to reduce the number of processes and thus reduce costs. The one-piece stamping can make the thickness of the base 1 uniform and prevent material waste.

[0092] When the LED lamp 100 is assembled, multiple screws are inserted through the aforementioned concentric ring breaks. These screws are passed through the multiple base screw holes 11 shown in the figure, as well as through the multiple shade screw holes 31 in the shade 3, thereby connecting the shade 3 to the base 1 and sandwiching the light source 2 therebetween. As shown in the figure, the multiple aforementioned breaks are located on the same straight line, forming radial pathways radiating from the center of the base plate 15 of the base 1, facilitating air convection and improving heat dissipation. Furthermore, because the breaks provide the connection points between the shade 3 and the base 1, their alignment facilitates the design of the shade 3 and enhances the aesthetics of the LED lamp 100.

[0093] In other embodiments, the lampshade 3 and base 1 may be connected without screw holes via adhesive bonding, thereby enhancing the waterproof performance of the LED lamp 100. The bonding location may be at the edge of the lampshade 3. Alternatively, adhesive may be applied to the gaps in the concentric rings to achieve a bonded connection.

[0094] The bottom plate 15 of the base 1 has a plurality of strip-shaped protrusions 12. Specifically, the strip-shaped protrusions 12 are protruding in the direction of light emission of the LED lamp. The strip-shaped protrusions 12 increase the heat dissipation area, and the ridge thereof has a hollow slit 121, which further helps to dissipate heat. The LED light strip 21 is located to the side of the strip-shaped protrusions 12. Because the base 1 is made of a metal plate and the strip-shaped protrusions 12 are protruding in the direction of the lampshade 3, the strip-shaped protrusions 12 can reflect the light emitted by the LED light strip 21 obliquely downward, which helps to enhance the light emission. Of course, in some embodiments, the strip-shaped protrusions 12 can also protrude in the opposite direction of the lampshade 3.

[0095] As previously mentioned, the multiple LED light strips 21 form two or more concentric rings. The aforementioned strip-shaped protrusions 12 can be located between the LED light strips 21 in adjacent rings, so that one strip-shaped protrusion can reflect the light emitted by two LED light strips 21. In this embodiment, the multiple LED light strips 21 form three concentric rings, and the multiple strip-shaped protrusions 12 form two concentric rings. In other words, the multiple LED light strips 21 and adjacent strip-shaped protrusions 12 are arranged concentrically, and the LED light strips 21 are also arranged parallel to the adjacent strip-shaped protrusions 12.

[0096] In addition, the strip-shaped protrusions 12 may also be arc-shaped, with multiple strip-shaped protrusions 12 forming multiple concentric rings. There are gaps between the strip-shaped protrusions 12 on the same ring, and they further share a common center with the concentric rings formed by the LED light strip 21. Such an arrangement not only makes the structure of each component compact, which helps to reduce the volume of the entire lamp, but also enables the strip-shaped protrusions 12 to surround the LED light strip 21 more tightly, thereby providing a better light reflection effect on the light emitted by the LED light strip 21. The multiple gaps between the multiple strip-shaped protrusions 12 are also radially distributed from the center of the bottom plate 15, which is beneficial to heat dissipation. At the same time, the LED light strip 21 is also radially distributed from the center (center) of the LED lamp to the periphery (edge) of the LED lamp.

[0097] The protruding strips 12 on different circular rings can have the same curvature. In other words, the number of protruding strips 12 on different circular rings can be the same. In other words, the lengths of the protruding strips 12 on different circular rings can be different. For example, the protruding strips 12 on the circular ring near the center of the LED lamp can be shorter than those on the circular ring near the edge of the LED lamp. Alternatively, the protruding strips 12 on the inner circular ring can be shorter than those on the outer circular ring. This allows the LED lamp to form multiple convection paths.

[0098] In other embodiments, the strip-shaped protrusions 12 on different circular rings may have different curvatures, that is, the number of strip-shaped protrusions 12 on different circular rings may be different. In one embodiment, the number of strip-shaped protrusions 12 on the inner ring is smaller than the number of strip-shaped protrusions 12 on the outer ring. This reduces the number of strip-shaped protrusions 12 on the base 1 while ensuring the strength of the base 1, thereby increasing the reflective area of ​​the strip-shaped protrusions 12 for the LED light strip.

[0099] In this embodiment, the inner ring includes two strip-shaped protrusions 12 , and the outer ring includes four strip-shaped protrusions 12 .

[0100] Furthermore, the length relationship between the individual strip-shaped protrusions 12 and the LED light strips 21 can be flexibly configured. For example, for a concentric ring consisting of multiple strip-shaped protrusions 12 and multiple LED light strips 21, the outermost ring of the LED light strips 21 can be longer than the outermost ring of the strip-shaped protrusions 12, the innermost ring of the strip-shaped protrusions 12 can be longer than the outermost ring, or the innermost ring of the strip-shaped protrusions 12 can be longer than the innermost ring of the LED light strips 21.

[0101] The height of each strip-shaped protrusion 12 is preferably within an appropriate range. If it is too high, it will affect the light output of the LED light strip 21, and if it is too low, it will affect the heat dissipation and reflective effect. The ratio of the height of each strip-shaped protrusion 12 to the vertical height of the side wall 14 of the base 1 (or it can be understood as the overall thickness of the base 1) is 0.1 to 0.4; preferably, the ratio of the height of each strip-shaped protrusion 12 to the height of the side wall 14 of the base 1 is 0.15 to 0.35; more preferably, the ratio of the height of each strip-shaped protrusion 12 to the height of the side wall 14 of the base 1 is 0.2 to 0.3. In other words, the bottom plate 15 of the base 1 includes at least two surfaces at two heights.

[0102] The power supply unit 4 is disposed within the insulating box 5, and the two are placed together within the accommodating portion 6. In other words, the accommodating portion 6 has a storage space within which the insulating box 5 and the power supply unit 4 are disposed. The insulating box 5 can be made of Mylar sheet. The accommodating portion 6 can be connected to the base 1 by snapping or threading. The height of the accommodating portion 6 (or the overall thickness of the accommodating portion 6) depends primarily on the size of the contents of the power supply unit 4 (electronic components or elements) and should not be too large. In this embodiment, the height of the accommodating portion 6 is no greater than the height of the sidewall 14 of the base 1 (or the overall thickness of the base 1) to prevent the power supply unit 4 from protruding from the base 1. The height ratio of the accommodating portion 6 to the base 1 can be selected to be 0.5 to 1; preferably, the height ratio of the accommodating portion 6 to the base 1 can be selected to be 0.6 to 1. More preferably, the height ratio of the accommodating portion 6 to the base 1 can be selected to be 0.75 to 1. Because the accommodating portion 6 is located inside the base 1, the height of the entire lamp is reduced compared to a method in which the power supply unit is located outside the base.

[0103] The accommodating portion 6 can be made of a reflective material, or coated with a reflective coating such as white paint, or covered with a reflective layer, etc. Thus, the light emitted toward the accommodating portion 6 can be reflected by the surface of the accommodating portion 6, thereby changing the light output angle and reducing the central dark area of ​​the LED lamp.

[0104] The ratio of the area of ​​the cross section of the accommodating portion 6 parallel to the bottom plate 15 to the area of ​​the bottom plate 15 of the base 1 can be 0.035 to 0.15; preferably, the ratio of the area of ​​the cross section of the accommodating portion 6 parallel to the bottom plate 15 to the area of ​​the bottom plate 15 of the base 1 can be 0.035 to 0.1; more preferably, the ratio of the area of ​​the cross section of the accommodating portion 6 parallel to the bottom plate 15 to the area of ​​the bottom plate 15 of the base 1 can be 0.035 to 0.07. The use of this numerical range for the accommodating portion 6 helps to avoid the formation of an obvious central dark area in the light output range. If the area occupied by the cross section of the accommodating portion 6 is too large, it is easy to cause the above-mentioned central dark area. In addition, the side and / or bottom surface of the accommodating portion 6 can be provided with LED light-emitting bodies to reduce the central dark area.

[0105] Referring to Figure 1A , the outer wall of the accommodating portion 6 is provided with a plurality of grooves 61. A plurality of tongues 62 are provided on the upper edge corresponding to the grooves 61, extending away from the outer wall and having a width approximately equal to that of the grooves 61. The tongues 62 securely connect the accommodating portion 6 to the base 1. Specifically, the tongues 62 may include a connecting hole through which a screw or other fixing member may pass to securely connect the accommodating portion 6 to the base 1. In other embodiments, the tongues 62 may also be secured to the accommodating portion 6 by other means, such as glue.

[0106] Referring to Figure 1A , the center of the accommodating portion 6 is provided with a central column 63 perpendicular to the bottom of the accommodating portion 6. This column 63 allows the power supply box 4 to be connected and secured to a mounting member, such as the mounting hole 13 on the base plate 15, allowing the power supply box 4 to be assembled and secured to the base 1. Specifically, the column 63 has internal threads, which allow the column 63 to be connected and secured to the mounting member via these internal threads. Furthermore, the column 63 may include a first end 631, which is connected and secured to the mounting member. The column 63 may also include a second end 632. Referring to Figure 1B , the second end 632 is located at the bottom of the accommodating portion 6 and can be used to connect components such as sensors. The base plate 15 has a mounting hole 13 in the center. This hole 13 has internal threads, allowing a screw to pass through and reach the first end 631 of the column near the base plate 15. The screw may be provided with a lifting ring or hook. Mounting holes may also be provided elsewhere on the base plate 15 to connect to a mounting bracket. The aforementioned hanging ring, hook, or mounting bracket is used to secure the entire lamp to a roof, wall, or other support structure. Referring to Figure 1B , the second end 632 of the center column is located at the bottom of the accommodating portion 6 and can be used to connect components such as sensors. Figure 3 is a schematic diagram of the external appearance of the LED lamp according to an embodiment of the present invention. Figure 3 shows the lamp from an upward perspective, with the sensor 8 connected to the bottom center of the accommodating portion 6.

[0107] The primary function of the lampshade 3 in this embodiment is to hold the light source 2. Specifically, it covers the LED illuminator 211 of the light source 2, completely covering the LED illuminator 211. Therefore, to improve heat dissipation, the areas of the lampshade 3 that are not in contact with the light source 2 are formed into a plurality of hollowed-out sections 32, which also saves material. Because the lampshade 3 is made of a translucent material, such as glass, resin, acrylic, or plastic, and in one embodiment of the present invention, a transparent material can be used, the lower surface of the lampshade 3 is formed into a protruding shape in this embodiment to form a lens. As shown in Figures 2A, 2B, and 2C, Figure 2A is a schematic diagram of the lampshade in this embodiment of the present invention, Figure 2B is a cross-sectional view taken along line AA of Figure 2A, and Figure 2C is an enlarged schematic diagram of point B of Figure 2B. As can be seen from Figures 2B and 2C, the lampshade 3 has a first protruding surface 331 and a second protruding surface 332, forming a convex lens. Light emitted by the LED illuminator 211 is refracted by the convex lens, diverging to both sides, creating a light diffusion effect. By selecting the curvatures of the first protruding surface 331 and the second protruding surface 332 , various light output angles of the entire lamp can be achieved, such as 120°, 90°, 60°, etc.

[0108] Referring to Figure 2A , the area where the lampshade 3 contacts the light source 2 also forms concentric circles. The lampshade 3 can include one or more circles. The number of circles of the lampshade 3 can be the same as the total number of light source 2, so that each circle of the lampshade 3 covers each circle of light source 2. In this embodiment, the lampshade 3 includes three circles. The figure shows the outermost circle 301, the middle circle 302, and the innermost circle 303 of the lampshade 3. Distributed around the innermost circle 303 are multiple protrusions 313 extending toward the center. The protrusions 313 allow electrical structures, such as wires, to pass through, thereby electrically connecting the light source 2 to the power supply 4. The multiple protrusions 313 correspond to the positions of the tongues 62 of the accommodating portion 6. When the accommodating portion 6 is inserted into the lampshade 3 from the top down, as viewed from Figures 1A or 1B , each protrusion 313 passes through each groove 61 and contacts the multiple tongues 62. In this way, the tongues 62 are sandwiched between the protrusions 313 and the bottom plate 15, thereby conveniently and reliably fixing the receiving portion 6. Moreover, electrical structures such as wires can enter the power supply unit 4 through the connection between the protrusions 313 and the tongues 62.

[0109] The LED lamp of the present invention is implemented in various embodiments as described above. It should be noted that in various embodiments, for the same LED lamp, features such as "the light source portion is mainly one or more LED light strips," "the LED light strip is provided with multiple LED light-emitting elements," "the LED light strip can be annular or substantially annular," "the annular shape formed by multiple LED light strips can be concentric rings," "the annular shape of the LED light strip can include one or more breaks," and "the LED light strip can also be arc-shaped or substantially arc-shaped" can be implemented individually or in an integrated manner in practice, so that only one feature or multiple features are implemented simultaneously.

[0110] For example, the light source portion is mainly one or more LED light strips, and a plurality of LED light-emitting bodies are provided on the LED light strips.

[0111] For example, the LED light strip may be ring-shaped or substantially ring-shaped.

[0112] In the above embodiment, the plurality of strip-shaped protrusions 12 can also be referred to as the heat sink of the LED lamp. The strip-shaped protrusions 12 (heat sinks) are disposed on the periphery of the power supply unit 4. That is, in the light emission direction of the LED lamp, the projections of the strip-shaped protrusions 12 (heat sinks) and the power supply unit 4 do not overlap, or in other words, the overlapping area is zero. The strip-shaped protrusions 12 (heat sinks) surround the power supply unit 4 but do not directly contact each other, i.e., they are spaced apart from each other. Similarly, the positional relationship between the light source unit 2 (or the illuminant 21) and the power supply unit 4 is the same as the positional relationship between the strip-shaped protrusions 12 (heat sinks) and the power supply unit 4.

[0113] Refer to Figures 4 and 5, which are overall schematic diagrams of the LED lamp in another embodiment of the present invention from different perspectives. As shown in the figure, the LED lamp 100 includes a base 1, and the outer contour of the base 1 is in the shape of a ring along the light emitting direction. A plurality of heat dissipation parts 16 are arranged along the ring structure pointing to the inside of the ring along the outer contour, that is, the base 1 includes at least one heat dissipation part 16, and the heat dissipation part 16 can be a heat dissipation fin along the optical axis direction of the LED lamp. The heat dissipation part 16 is along the ring where the outer contour of the base 1 is located, and is evenly distributed along the radial direction of the ring. The heat dissipation part 16 points to the center of the ring where the base 1 is located, and one end of at least one heat dissipation part 16 is in contact with and fixed to the power supply part 4 located at the center of the ring of the base 1, and the other end is fixed to the outer contour of the base 1, thereby achieving the fixation of the power supply part 4.

[0114] Referring to Figures 6 and 7, Figure 6 is a schematic diagram of the power supply unit 4 and the hanging assembly 9 in an assembled state, and Figure 7 is a schematic diagram of the power supply unit 4 and the hanging assembly 9 in an exploded state, according to an embodiment of the present invention. The power supply unit 4 is cylindrical, with its circumference at least partially in contact with the heat dissipation unit 16. A hanging assembly 9 is disposed on one surface of the power supply unit 4. The hanging assembly 9 has a threaded portion 91 at one end, a hanging portion 93 at the other end, and a movable closure member 94 that cooperates with the hanging portion 93. The hanging assembly 9 cooperates with the mounting hole 13 on the power supply unit 4 via the threaded portion 91 to achieve connection and fixation. The hanging portion 93 and the movable closure member 94 secure the power supply unit 4 to the mounting environment, while the power supply unit 4 is secured to the heat dissipation unit 16 (i.e., the base 1). Thus, the LED lamp 100 can be secured to the mounting environment. The movable closure member 94 can open and close relative to the hanging portion 93 to form a fully enclosed ring structure or a semi-enclosed ring structure, thereby enabling the LED lamp to be secured to and removed from the mounting environment.

[0115] The hanging component 9 has an end face with a diameter larger than that of the threaded portion 91 at one end of the threaded portion 91. The end face extends outward along the radial direction of the threaded portion 91 for a certain distance to form an extension portion. At least one limiting through hole 95 is provided on the extension portion, and a corresponding limiting hole 41 is provided on the power supply portion 4. A locking piece 93 passes through the limiting through hole 95 and is rotated with the limiting hole 41 to achieve limiting, thereby preventing the connection between the power supply portion 4 and the hanging component 9 from loosening or falling off due to vibration or gravity during use of the LED lamp 100.

[0116] In a traditional setting, the mounting hole 13 will protrude outward, for example, relative to the power supply unit 4, so as to achieve the fixation of the hanging component 9. Furthermore, the threaded portion 91 is accommodated by the outwardly protruding mounting hole 13, and the locking member 93 is also arranged horizontally, that is, roughly parallel to the light-emitting surface of the LED lamp. Under the influence of vibration, it is easy to fall off outward and affect the integrity and reliability of the overall structure of the LED lamp.

[0117] In the present invention, the components inside the power supply part 4 are arranged so that the mounting hole 13 is recessed in the power supply part 4, which can reduce the height of the LED lamp relative to the traditional convex structure; at the same time, the threaded part 91 is provided with an extension part, which is roughly parallel to the light-emitting surface of the LED lamp, and a limiting through hole 95 is provided, which is matched with the concave limiting hole 41 on the power supply part 4, so that the locking piece 93 can be in a vertical state, that is, roughly perpendicular to the light-emitting surface of the LED lamp, that is, the plane where the light source part 2 is located, and the locking piece 93 and the limiting hole 41 are threaded together. Most of the force generated by the vibration of the LED lamp is in the up and down or horizontal direction, rather than the force rotating around the axis, and it is difficult for the locking piece 93 and the limiting hole 41 to loosen or disengage, thereby greatly improving the reliability of the LED lamp.

[0118] 8 is a schematic diagram of an LED lamp 100 in one embodiment of the present invention after the hanging assembly 9 is disassembled. In one embodiment of the present invention, the power supply unit 4 and the base 1 are integrally formed, and the hanging assembly 9 is fixed to the power supply unit 4 via a threaded structure.

[0119] In other embodiments of the present invention, the hanging assembly 9 and the power supply unit 4 can also be fixed by buckles.

[0120] In another embodiment of the present invention, the power supply unit 4 and the base 1 are separate structures, and the power supply unit 4 is fixed by welding, snapping, gluing, screws, etc.

[0121] Referring to Figures 9 and 10, which are schematic cross-sectional views along the radial direction of the base 1 from two perspectives, the front and back, of an LED lamp in one embodiment of the present invention. As shown in the figure, the light source portion 2 is a hollow annular plate, and a snap-fit ​​portion is provided on the heat dissipation portion 16 for snapping the light source portion 2, and the heat dissipation portion 16 is perpendicular to the surface of the light source portion 2. The heat generated by the light source portion 2 during operation is guided and dissipated through the heat dissipation portion 16, and the heat dissipation portion 16 is perpendicular to the surface of the light source portion 2. The heat dissipated by the light source portion 2 will not be blocked or hindered by the surface of the heat dissipation portion 16, thereby improving the heat dissipation effect of the LED lamp. In other words, the light source portion 2 is composed of a light source board and a plurality of LED lamp beads (LED light-emitting bodies) arranged on the light source board (not shown in the figure), and the heat dissipation portion 16 is composed of a plurality of heat dissipation fins, the surfaces of the heat dissipation fins are perpendicular to the surface of the light source board, that is, the surfaces of the heat dissipation fins are along the vertical direction or parallel to the vertical direction, that is, parallel to the optical axis of the LED lamp.

[0122] The light source part 2 is hollow and the power supply part 4 is completely exposed. The power supply part 4 is connected and fixed to the heat dissipation part 16, and the heat dissipation parts 16 are spaced apart from each other (that is, the heat dissipation fins are spaced apart from each other). The light source part 2 and the power supply part 4 are connected through the heat dissipation part 16 (or heat dissipation fins), and the light source part 2 and the power supply part 4 are spaced apart from each other by a certain distance. The heat dissipation part 16 (or heat dissipation fins) forms a heat dissipation channel 42 (see Figure 5) that passes through from top to bottom between the light source part 2 and the power supply part 4, that is, it extends along the optical axis direction of the LED lamp. The heat dissipation part 16 is parallel to the heat dissipation channel 42, that is, the heat dissipation fins of the heat dissipation part 16 are parallel to the extension direction of the heat dissipation channel 42, and can quickly take away the heat of the LED lamp through air convection.

[0123] That is, the projections of the heat sink 16 and the light source 2 in the direction of light emission from the LED lamp do not overlap, or the overlapping area is zero. The heat sink 16 surrounds the power source 4, but they are not in direct contact with each other, i.e., they are spaced apart. Similarly, the positional relationship between the light source 2 and the power source 4 is the same as that between the heat sink 16 and the power source 4.

[0124] In one embodiment of the present invention, the heat dissipation portion 16 includes heat dissipation fins of at least two shapes (lengths), and at least part of the heat dissipation fins are connected to the power supply portion 4 .

[0125] FIG11 is a schematic diagram of an LED lamp according to another embodiment of the present invention. As shown, the LED lamp 100 includes a base 1, as described above, serving as the main structure of the lamp body; a heat sink 16 disposed on one side of the base 1; and a power supply 4 disposed between the base 1 and the heat sink 16. A hanging assembly 9 is disposed on the power supply 4. The hanging assembly 9 and the power supply 4 have two relative positional relationships: one in which the hanging assembly 9 and the power supply 4 are relatively rotatable, referred to as the movable state; and the other in which the hanging assembly 9 and the power supply 4 are fixed relative to each other, referred to as the fixed state. For example, when the LED lamp 100 is not yet installed in its intended use, the hanging assembly 9 can be rotated relative to the power supply 4 (or, more specifically, relative to the LED lamp 100) to facilitate transportation and packaging. Specifically, the hanging assembly 9 can be rotated to a position close to the plane of the base 1 and positioned flat above the heat sink 16, positioned below the highest plane of the power supply 4 in the thickness direction of the LED lamp (i.e., the light emitting direction). This reduces the thickness of the LED lamp during packaging and transportation.

[0126] In short, when the device is packaged for transportation, the hanging assembly 9 is disposed above the heat dissipation portion 16 and is lower than the power supply portion 4 in the thickness direction.

[0127] Once the LED lamp 100 is installed, the hanging assembly 9 is fixed relative to the power supply unit 4 (or, in other words, fixed relative to the LED lamp 100). This means that the relative position of the two cannot be easily changed, ensuring the stability of the LED lamp 100 after it is installed. It is worth noting that the power supply unit 4 is also provided with at least one power notch 400, which is recessed inward relative to the power supply unit 4.

[0128] In some embodiments, the power gap 400 can be used to arrange the power cords, making the power cords neater and more organized, while providing a certain space for installing the power cords.

[0129] In some embodiments, when the LED lamp 100 is not installed in a usage environment, at least a portion of the hanging assembly 9 can be accommodated in the power gap 400 .

[0130] 12A and 13A are schematic diagrams of the front view of an LED lamp in an embodiment of the present invention. The base 1 comprises a bottom surface 15 and side walls 14. The base 1 (or bottom surface 15) has a first surface and a second surface. The heat dissipation portion 16 is disposed on the first surface of the base 1, and the light source portion 2 is disposed on the second surface of the base 1. The light source portion 2 is generally annular in structure with a hollow center. The area of ​​the hollow area is equal to or larger than the projection of the power supply portion 4 along the light emitting direction of the LED lamp. In other words, the power supply portion 4 can be completely accommodated within the hollow area, or the power supply portion 4 is disposed within the hollow area. The power supply portion 4 includes a power module 40. A light sensor 8 is connected to the power module 40. The light sensor 8 can sense the external light environment and output a signal. The LED lamp receives the signal and controls the light output, for example, by controlling the electronic components in the power supply portion 4 to control the light output.

[0131] Of course, in some other embodiments, the light sensor 8 can also be replaced by other sensors, such as integrated light sensor, temperature sensor, humidity sensor, infrared sensor, sound sensor, etc.

[0132] 11 to 13 , it can be seen that the LED lamp 100 is provided with a heat dissipation channel 42 that runs through the upper and lower parts, i.e., the LED lamp 100 is completely penetrated in the thickness direction. In the thickness direction, external gas passes through the heat dissipation channel 42 to circulate inside the LED lamp, and the heat generated by the LED lamp during operation is taken away by gas convection, thereby improving the heat dissipation capacity of the LED lamp, and further improving the service life and luminous efficiency of the LED lamp.

[0133] In one embodiment, the heat dissipation channel 42 includes a first heat dissipation channel 42', a second heat dissipation channel 42", and a third heat dissipation channel 42'". The first heat dissipation channel 42', the second heat dissipation channel 42", and the third heat dissipation channel 42' are distributed in a concentric ring structure, wherein the first heat dissipation channel 42' is arranged at the outermost edge of the LED lamp, that is, between the bottom surface 15 and the side wall 16, the third heat dissipation channel 42'' is arranged at the inner edge of the LED lamp near the power supply unit 4, and the second heat dissipation channel 42'' is arranged between the first heat dissipation channel 42'' and the third heat dissipation channel 42''. That is, the radius of the first heat dissipation channel 42' is greater than the radius of the second heat dissipation channel 42", and the radius of the second heat dissipation channel 42'' is greater than the radius of the third heat dissipation channel 42''.

[0134] In this embodiment of the present invention, the power supply unit 4 (or the power module 40) is a roughly cylindrical structure, and the radius of the power supply unit 4 (or the power module 40) is smaller than the radius of the third heat dissipation channel 42', that is, along the light emitting direction of the LED lighting fixture, the projection of the power supply unit 4 (or the power module 40) is completely within the third heat dissipation channel 42'.

[0135] In one embodiment of the present invention, the heat dissipation portion 16 includes a plurality of heat dissipation fins. These fins are radially distributed around the power supply portion 4 and have a certain height in the thickness direction of the LED lamp. The heat dissipation fins are parallel to the flow direction of the gas through the heat dissipation channel 42, or do not hinder the flow of gas. During the flow, the gas at least partially flows over the surfaces of the heat dissipation fins, removing at least a portion of the heat from the heat dissipation fins.

[0136] At least part of these heat dissipation fins are in contact with the light source part 2 and the power supply part 4, or form a heat conduction path. When the LED lamp is working, at least part of the heat generated by the light source part 2 and the power supply part 4 can be transferred to the heat dissipation fins (or the heat dissipation part) through heat conduction. The heat dissipation fins greatly increase the heat dissipation area of ​​the LED lamp. Combined with the provision of heat dissipation channels 42 to provide gas convection, the heat dissipation capacity of the LED lamp can be effectively improved.

[0137] Referring to FIG12B , FIG12B is an exploded schematic diagram of an LED lighting fixture according to another embodiment of the present invention, wherein the base 1 includes an annular sidewall 14 and a hollow annular bottom surface 15. The sidewall 14 is substantially perpendicular to the bottom surface 15 and surrounds the bottom surface 15. A first heat dissipation channel 42' is provided between the bottom surface 15 and the sidewall 14, i.e., the first heat dissipation channel surrounds the outer periphery of the bottom surface 15 and is embedded in the inner periphery of the sidewall 14. The light source portion 2, or the light source board 20, is fixed to the bottom surface 15. A plurality of annular LED light strips 21 are provided on a surface of the light source board 20 away from the bottom surface 15, and the plurality of LED light strips 21 are arranged concentrically with each other. Each LED light strip includes a plurality of LED illuminators 211, i.e., the light source board 20 is provided with a plurality of LED illuminators. A lampshade 3 is provided in the light emitting direction of the LED light emitting body 211. The lampshade 3 is provided with a plurality of annular strip lenses corresponding to the LED light strip 21. The shape of the lampshade 3 matches the shape of the light source board 20. When the light source board 20 is an annular hollow structure, the lampshade 3 is also an annular hollow structure. The inner and outer peripheries of the lampshade 3 are provided with a plurality of lampshade fixing parts 35. The lampshade fixing parts 35 are provided with screw holes. The lampshade 3 is fixed to the base 1, or fixed to the bottom surface 15, by screws. That is, the lampshade 3 and the base 1 (or the bottom surface 15) clamp the light source part 2 (or the light source board 20).

[0138] Referring to Figures 12A to 13B, in one embodiment of the present invention, the light source unit 2 includes a light source board 20, an LED light strip 21 disposed on the light source board 20, and the LED light strip 21 includes a plurality of LED illuminators 211. Of course, in some embodiments, the plurality of LED illuminators 211 may be directly disposed on the light source board 20, and the LED illuminators 211 may be arranged in any shape. The light source unit 2 also includes a lampshade 3, which is integrally disposed on the light source board 20 and completely covers the LED light strip 21 (or illuminators 211). The lampshade 3 has a specific surface shape. In this embodiment, the lampshade 3 includes a plurality of concentric annular protrusions (i.e., annular lenses). The annular protrusions form an arcuate groove 34 on the side facing the LED illuminators 211. The arcuate groove 34 can be used to accommodate the LED illuminators 211, i.e., at least a portion of the LED illuminators are accommodated within the arcuate groove, thereby increasing the distance between the lampshade 3 and the LED illuminators 211 without increasing the overall height of the LED lamp. The annular protrusion is an arc-shaped protrusion 33 in the light emitting direction of the LED lamp (ie, the direction away from the LED light-emitting body 211 ), and the arc-shaped protrusion 33 forms a convex lens structure, which has a diffusion effect on the light emitted by the LED light-emitting body 211 .

[0139] Referring to FIG. 14 , which is a schematic diagram of gas flow in an LED lamp according to an embodiment of the present invention, the dashed arrows in the figure are schematic diagrams of gas flow, wherein the outermost dashed arrow A' is a schematic diagram of the path of gas flowing through the first heat dissipation channel 42'; the middle dashed arrow A" is a schematic diagram of the path of gas flowing through the second heat dissipation channel 42"; and the innermost dashed arrow A"' is a schematic diagram of the path of gas flowing through the third heat dissipation channel 42'. As shown in the figure, the gas flows from below the LED lamp to above the LED lamp, which is opposite to the light emission direction of the LED lamp. That is, when the LED lamp is operating, the heat generated heats the air near the LED lamp, and the hot air has a low density and tends to rise. The heat dissipation channel 42 provides an air flow channel, through which cold air from the outside can be continuously replenished. The LED lamp can achieve a circulation mode in which hot air rises and leaves and cold air is replenished without the need for additional drive, thereby achieving efficient gas convection heat dissipation. The first heat dissipation channel 42' and the second heat dissipation channel 42" can dissipate heat from the light source part 2 from the outside and inside of the circular ring of the light source part 2 respectively, effectively enhancing the heat dissipation capacity of the light source part 2; the second heat dissipation channel 42" and the third heat dissipation channel 42"' can dissipate heat from the power supply part 4, that is, the heat dissipation channel 42 improves the overall heat dissipation capacity of the LED lamp.

[0140] Continuing to refer to FIG14 , the light sensor 8 is completely covered by the projection of the power supply unit 4 in the light emitting direction of the LED lamp, that is, in the projection direction, it is completely contained in the hollow area of ​​the light source unit 2 and will not block the light emitting from the light source unit 2.

[0141] In some other embodiments of the present invention, the surface of the light sensor 8 has a light reflection function, which is achieved through the material of the light sensor 8 itself, or an additional coating, or a film (sheet); further, diffuse reflection is preferred, that is, a microstructure is set on the surface of the light sensor 8 to achieve diffuse reflection, such as a frosted structure.

[0142] Please refer to FIG. 15 , which is an exploded view of an LED lamp in an embodiment of the present invention. As shown in the figure, a flat clamping portion 401 is provided on the edge of the power supply portion 4 , and the flat clamping portion 401 is used to fix the hanging component 9 .

[0143] The hanging assembly 9 includes a hanging portion 92 as the main body. The hanging portion 92 is an arc-shaped structure, and flat joints 921 are provided at both ends of the arc. The flat joint 921 is provided with a joint through hole 922. When the LED lamp is assembled, the flat joint 921 is inserted into the flat clamping portion 401. The flat clamping portion 401 is provided with a through hole corresponding to the joint through hole. The joint through hole 922 and the corresponding through hole on the flat clamping portion 401 are fixed by screws or bolts to realize the assembly of the hanging assembly 9.

[0144] At least one joint limiting structure 924 is also provided on the flat joint 921, and the joint limiting structure 924 can cooperate with the internal structure of the flat clamping portion 401 (not shown) to realize the positioning of the hanging component 9; for example, in some embodiments, the joint limiting structure 924 is a convex structure, and the flat clamping portion 401 has a corresponding concave structure. When the hanging component 9 is rotated to a certain angle, the convex and concave structures are locked with each other. At this time, the relative position of the hanging component 9 will not change easily, and a greater force is required to disengage the convex and concave structures; in another embodiment of the present invention, the joint limiting structure 924 is a concave structure, and the flat clamping portion 401 is provided with a convex structure.

[0145] In some embodiments of the present invention, the joint limiting structure 924 may not be provided.

[0146] In the present invention, the hanging support assembly 9 also includes a mounting screw 96, which can be locked to the installation environment to fix the LED lamp. A mounting screw through hole 961 is provided on the mounting screw 96, and the hanging part 92 is passed through the mounting screw through hole; at least one mounting screw limiting portion 923 is also provided on the hanging part 92, which is used to install the screw 96 now to prevent it from sliding relative to the hanging part 92.

[0147] In one embodiment of the present invention, hollow holes are provided to form air channels inside and outside the LED lamp, thereby achieving air convection inside and outside the LED lamp and rapidly cooling the lamp.

[0148] 16A to 23 , the LED lamp of the present invention includes a base 1 , a light source 2 , a power supply 4 and a hanging assembly 9 .

[0149] Referring to Figures 17 to 18B , the base 1 includes a bottom plate 15 and sidewalls 14. The bottom plate 15 and sidewalls 14 of the base 1 form a housing space, in which the light source unit 2 is housed. The bottom plate 15 of the base 1 is preferably flat, and the light source unit 2 is fixed to the bottom plate 15 in a relatively parallel position. More specifically, the light source unit 2 is fixed to a surface of the bottom plate 15 in a relatively parallel position within the housing space formed by the bottom plate 15 and sidewalls 14. In other embodiments of the present invention, the bottom plate 15 of the base 1 may include a first hollow hole 151 connecting the inside and outside of the housing space. The first hollow hole 151 is used to allow gas flow. The gas can be air. The air can flow from the housing space through the first hollow hole 151 to the outside of the housing space, or from the outside of the housing space through the first hollow hole 151 to the housing space. The heating elements of an LED lamp during operation are generally LED lamp beads and a power supply, namely, the light source unit 2 and the power supply unit 4 in this document.

[0150] In the present invention, the base 1 can be configured in a trumpet shape, that is, the diameter of the base 1 has a certain difference (variation) along the axial direction, so that the base 1 gradually changes regularly or irregularly along the axial direction, forming a final state with one end being large and the other end being small. In this embodiment, the base 1 has a smaller diameter at the end where the bottom plate 15 is located, and a larger diameter at the end away from the bottom plate, that is, the diameter of the base 1 at the end where the bottom plate 15 is located is smaller than the diameter of the end away from the bottom plate 15. In other words, the base 1 is composed of a bottom plate 15 and a side wall 14 surrounding the bottom plate 15, and the side wall 14 is arranged on the same side of the bottom plate 15 and extends in one direction. In one embodiment of the present invention, the base plate 15 is circular or nearly circular, but may also be other shapes, such as elliptical, rectangular, or spherical. The sidewalls 14 surround the base plate 15 to form a truncated cone-like structure, wherein the diameter of the sidewall 14 at the end closest to the base plate 15 is less than or equal to the diameter of the sidewall 14 at the end away from the base plate 15 (see FIG16A ). That is, the end of the sidewall 14 closest to the base plate 15 has a first diameter D1, and the end away from the base plate has a second diameter D2. The first diameter D1 is less than or equal to the second diameter D2, i.e., the diameter along a direction perpendicular to the optical axis of the LED lamp. That is, in the base 1, the first diameter D1 is formed at the end of the sidewall 14 connected to the base plate 15, and the second diameter is formed at the end of the sidewall 14 opposite the end away from the base plate 15, wherein the first diameter is less than or equal to the second diameter. Alternatively, the radius of the LED lamp gradually increases along the light emission direction of the LED lamp. The light source unit 2 and the power supply unit 4 of the components that generate heat during operation are arranged near the base plate 15, that is, at the end with a smaller diameter. The light source unit 2 is arranged on the side of the base plate 15 facing the side wall 14, and the power supply unit 4 is arranged on the side of the base plate 15 facing away from the side wall 14, that is, on different sides of the base plate 15, to reduce the mutual influence between the heat generated by the light source assembly 20 and the heat generated by the power supply unit 4, while the end of the base 1 with a larger diameter is in an open and unobstructed state. The components that generate heat will increase the temperature of the components in the vicinity thereof, including the components that are in direct and indirect contact with them, as well as the air. When there is a relative temperature difference in the air, the air will produce relative flow, such as the relative flow of cold air and hot air. In this embodiment, the components that generate heat, that is, the light source unit 2 and the power supply unit 4, are arranged at the base plate 15, that is, at the position where the diameter of the LED lamp is smaller, resulting in a higher relative temperature of the air at the position with a smaller diameter, while the relative temperature of the air in the area where the diameter of the LED lamp is larger and at the position of the base away from the base plate 15 is lower.Furthermore, when the LED lamp is working, the horizontal height of the end with a smaller diameter is greater than the horizontal height of the end with a larger diameter. The end with a relatively higher temperature is the end with a smaller diameter where the base plate 15 is located, and the air temperature near it is relatively high, causing hot air to rise and move to the outside of the lamp through the first hollow hole 151; when the air near the base plate 15 (the end with a smaller diameter) moves to the outside of the lamp, a local air pressure difference is formed between the end with a smaller diameter and the end with a larger diameter, that is, the air pressure near the end with a smaller diameter is lower than the air pressure near the end with a larger diameter, and the air at the end with a larger diameter moves toward the air at the end with a smaller diameter. Furthermore, the gas flow rate can be roughly expressed as flow rate = V / (T×S), where T represents time, V represents the volume of gas, and S represents the cross-sectional area of ​​the pipe. Based on the volume V of air discharged within the compressed air time T and the cross-sectional area S of the pipe, the flow rate in the pipe can be calculated, i.e., the speed of movement within the base 1 (which can be roughly considered a pipe). When other conditions remain unchanged, the diameter of the pipe decreases, i.e., when S decreases, the flow rate increases. The movement of air from the larger diameter end of the base 1 to the smaller diameter end is a gradually accelerating process. During operation, relatively cool air continuously flows in from the larger diameter end of the base 1 and flows out from the smaller diameter end, quickly removing heat from the light source 2 and power supply 4. Furthermore, directional airflow can be achieved without the need for additional active heat dissipation components (such as fans), achieving passive airflow drive. Furthermore, it can be said that the undesired heat generated as a byproduct of the lamp's operation is used as a driving source to drive the airflow, achieving waste energy utilization and optimizing heat dissipation, as shown in Figure 16B. The flowing gas enables rapid heat exchange between the interior of the accommodation space and the external environment, and removes the heat emitted by the light source unit 2 accommodated in the accommodation space of the base 1 at a faster rate, effectively reducing the temperature of the LED lamp and prolonging the life of the LED lamp. The base 1 acts as the lamp body of a traditional high-power LED lamp, and adopts the hollow holes provided on the base 1 for heat dissipation. Compared with the traditional heat dissipation through heat sinks, the structure is simplified, and the production cost and process difficulty are reduced. The base 1 can be arranged in a trumpet shape, and the diameter of the bottom plate 15 of the base 1 is smaller than the diameter of the opening of the base 1. A reflective layer can also be provided in the side wall 14 of the base 1. The base 1 can protect the light source unit 2. At the same time, the reflective layer on the inner wall of the base 1 can increase the light emission rate and the luminous brightness of the light source unit 2. The reflective layer on the inner wall of the base 1 can be formed by the material properties of the base 1 itself, or by an additional coating or film-sticking process, or by the additional provision of other materials (such as an additional smooth metal sheet that fits the side wall 14). As a preferred method, the base 1 is made of metal. Metal has good thermal conductivity. Materials with good thermal conductivity tend to absorb heat quickly and dissipate heat quickly. The metal base 1 can quickly transfer the heat of the light source part 2 and dissipate it quickly, which can quickly reduce the temperature of the light source part 2 and increase the life of the LED lamp.The base 1 can be made of silver, copper, aluminum, tungsten, magnesium and other materials. In this embodiment, the base 1 is made of aluminum. Aluminum has good thermal conductivity and low density, which can reduce the weight of the base 1. In addition, the price of aluminum is low, which reduces the production cost.

[0151] The light source part 2 is disposed in the accommodation space of the base 1 , and the light source part 2 is used for emitting light and lighting.

[0152] The power supply unit 4 is disposed on a side of the bottom plate 15 of the base 1 away from the light source unit 2 (or on the other side relative to the side connected to the light source unit 2) and is electrically connected to the light source unit 2. The power supply unit 4 supplies power to the light source unit 2. Preferably, the power supply unit 4 is detachably connected to the bottom plate 15 of the base 1. This facilitates quick installation of the power supply unit 4 to the bottom plate 15 of the base 1 or quick removal of the power supply unit 4 from the base 1, improving assembly efficiency and facilitating the installation and maintenance of the LED lamp. Furthermore, if a component of the lamp is damaged, it can be removed and replaced as needed without replacing the entire lamp, thus achieving modular assembly and replacement of lamp components and reducing subsequent maintenance costs. (See FIG. 20A ) The power supply unit 4 is secured to the base 1 via a cover plate 420 within the power supply unit 4. The cover plate 420 is provided with a second latch 421. The bottom plate 15 of the base 1 may include a second latch slot 153. The second latch 421 on the cover plate 420 and the second latch slot 153 on the bottom plate 15 cooperate to secure the power supply unit 4 to the base 1. It is worth mentioning that the second slot 153 includes an insertion portion 1531 and a fastening portion 1532. The width of the insertion portion 1531 along the radial direction of the base 1 is much greater than the width of the fastening portion 1532 along the radial direction. The second clip 421 may include a bent structure, which can be configured into an L-shape. Referring to Figure 20B, the second clip 421 is L-shaped and includes an extension portion 4211 and a bent portion 4212. The bent portion 4212 is roughly parallel to the bottom plate 15 of the base 1. The projection of the bent portion 4212 along the vertical direction of the bottom plate 15 of the base 1 can be completely accommodated by the insertion portion 1531, or in other words, the outer peripheral contour of the bent portion 4212 is slightly smaller than the contour of the insertion portion 1531, so that the bent portion 4212 can pass through the insertion portion 1531. The thickness of the extension portion 4211 is slightly less than or equal to the radial width of the fastening portion 1532. To secure the power supply unit 4 to the base 1, first insert the bent portion 4212 through the insertion portion 1531, ensuring that the bent portion 4212 completely passes over the base 15 in a direction perpendicular to the base 15, without interfering with each other during rotation. The power supply unit 4 and the cover 420 are then rotated, allowing the extension portion 4211 to engage with the fastening portion 1532, thereby quickly securing the power supply unit 4 to the base 1. Specifically, align the second clip 421 with the second slot 153, press downward, and then rotate to a certain angle to secure the power supply unit 4 to the base 1.

[0153] In one embodiment, the thickness of the extension portion 4211 varies from small to large. The thickness of the extension portion 4211 on the side close to the fastening portion 1532 is less than the width of the fastening portion 1532 along the radial direction. The thickness of the extension portion 4211 gradually increases toward the side away from the fastening portion 1532, and is eventually slightly greater than or equal to the width of the extension portion 4211, so that the extension portion 4211 can quickly enter the fastening portion 1532 and finally achieve clamping and fixing, such as interference fit.

[0154] In one embodiment, the curvature of the extension portion 4211 is slightly smaller than that of the fastening portion 1532 so that when the extension portion 4211 is screwed into the fastening portion 1532, the extension portion 4211 is slightly deformed, and the extension portion 4211 and the fastening portion 1532 are pressed against and compressed against each other to be fixed more firmly.

[0155] In one embodiment, the extension portion 4211 is tilted, meaning that the linear distance between the bent portion 4212 and the center of the bottom plate 15 is less than the linear distance between the intersection of the extension portion 4211 and the cover plate 420 and the center of the bottom plate 15. Furthermore, the second clip 421 exhibits a certain degree of elasticity, allowing for slight deformation. The outer radius of the bottom portion of the second clip 421, i.e., the bent portion 4212, is slightly less than or equal to the outer radius of the insertion portion 1311. The radius of the arc of the extension portion 4211 gradually increases as it moves from the bent portion 4212 toward the cover plate 420. When the power supply unit 4 and the base 1 are fixed, the power supply unit 4 is slightly pressed downward, that is, the second clip 421 passes through the insertion portion 1531. The second clip 421 passes through the insertion portion 1531 through a certain pressure, and its extension portion 4211 is pressed against the outer periphery of the insertion portion 1531. As the radius of the extension portion 4211 gradually increases, it is forced to deform toward the center of the bottom plate 15 (of course it can also be the center, the bottom plate 15 can also be other shapes, such as a rectangle, etc.), and tends to move away from the center of the bottom plate 15, applying a pressure to the outer periphery of the insertion portion 1531. When the extension portion 4211 is screwed into the fastening portion 1532, on the one hand, the width of the extension portion 42111 is greater than the fastening portion 1532, and the second clip 421 cannot come out. On the other hand, the extension portion 4211 is deformed and presses against the fastening portion 1532, making it difficult for the second clip 421 to slide relative to the fastening portion 1532, thereby avoiding abnormal noise or loosening and improving the fixing effect.

[0156] In one embodiment, the extending portion 4211 has a groove corresponding to the fastening portion 1532 , and the extending portion 4211 and the fastening portion 1532 can be partially embedded.

[0157] In one embodiment, a magnetic element is provided on the bending portion 4212 , and a magnetic element is also provided near the fastening portion 1532 , and the two attract each other to achieve better fixation.

[0158] When the power supply unit 4 and the base 1 are to be disassembled, the disassembly is completed by rotating them in the reverse direction or applying a certain pressure and then rotating them in the reverse direction, and completely withdrawing the second clip 421 from the insertion portion 1531 .

[0159] The volume of the accommodating space of the base 1 is larger than the volume of the power supply unit 4. During packaging, the light source unit 2 and the power supply unit 4 can be placed together in the accommodating space of the base 1. Only one packaging box is required, and there is no need to package the various parts of the LED lamp separately, which saves packaging costs and improves packaging and transportation efficiency. During installation, the light source unit 2 is set in the accommodating space of the base 1, and the power supply unit 4 is set on the side of the bottom plate 15 of the base 1 away from the light source unit 2. The power supply unit 4 is set on the outside of the base 1 and there is a certain distance between it and the light source unit 2 to avoid the heat generation of the power supply unit 4 and the heat generation of the light source unit 2 from aggravating each other, and at the same time it is beneficial to the heat dissipation of the power supply unit 4. Furthermore, the power supply unit 4 is surrounded by the first hollow hole and is in the air outlet direction, which accelerates the heat dissipation of the power supply unit 4.

[0160] In a specific embodiment, the light source portion 2 includes a light source board 20 and a lampshade 3. The light source board 20 is provided with lamp beads (i.e., LED illuminants 211, not shown). The lamp beads are used to emit light and are evenly distributed along the light source board 20. The lamp beads can be LED lamp beads. The lampshade 3 is arranged in front of the light-emitting direction of the lamp beads and completely covers the lamp beads (on the LED illuminants 211), that is, completely covers the lamp beads (LED illuminants 211). The lampshade 3 can be made of a light-transmitting material, such as glass, resin, acrylic, plastic and other materials. The lampshade 3 can be fixed to the light source board 20 or the base 1 and completely cover the light source board 20. Furthermore, the projection of the lampshade 3 can completely cover the light source board 20 in the direction perpendicular to the light source board 20, thereby forming a relatively sealed environment, thereby effectively protecting the light source board 20 and the related components fixed on the light source board 20.

[0161] The lampshade 3 can be a PC cover or a lens. On the one hand, the lampshade 3 can protect the lamp beads from damage, and on the other hand, it can adjust the light emission angle of the light emitted by the lamp beads, thereby enhancing the utilization efficiency of the light emitted by the lamp beads and the luminous efficiency of the lamp beads. For example, in one embodiment of the present invention, the lampshade 3 can be a lens that is convex relative to the light source board 20 toward the light emission direction of the LED lamp beads. The lens is a curved surface with a certain curvature, and the side facing the light source board 20 is a concave cavity, so that the light source board 20 and at least one electronic component can be accommodated in the concave cavity. At the same time, the lampshade 3 is a convex lens that is convex along the light emission direction of the LED lamp beads, which has a light diffusion and homogenization effect relative to the light emission of the LED lamp beads (i.e., LED light-emitting body), thereby expanding the light emission angle of the lamp and reducing glare. Furthermore, compared to conventional LED lamps, the aforementioned structure eliminates the face ring. In conventional lamps, the light panel lens is secured by a face ring with an outer diameter slightly larger than the lens's, and an inner diameter slightly smaller. This face ring is typically screwed to the base plate 15, with a portion of the face ring's structure fitting over a portion of the lens near the outer diameter, pressing the lens onto the light source board 20 and securing it there, further strengthening the fixation of the light source board 20. The lampshade 3 (or lens) itself includes a fixing structure, eliminating the need for a face ring to secure the lens. This significantly simplifies the lamp structure, improves assembly efficiency, and reduces production costs.

[0162] The power supply unit 4 includes a power module 40, which is disposed on a side of the bottom plate 15 of the base 1 away from the light source unit 2 and is electrically connected to the light source unit 2. The power supply unit 4 also includes a cover plate 420, on which the power module 40 is disposed. The cover plate 420 is disposed on a side of the bottom plate 15 of the base 1 away from the light source unit 2. The cover plate 420 is provided with a second hollow hole 423, which corresponds to the first hollow hole 151 and is used to allow the flow of gas, which can be air. The air can pass through the first hollow hole 151 and the second hollow hole 423, removing heat from the air, effectively reducing the temperature of the LED lamp, preventing the effects of high temperatures on the lamp's electronic components and potentially heat-sensitive materials, and thus extending the life of the LED lamp. Specifically, the annular band containing the first hollow hole 151 and the second hollow hole 423 forms a heat sink for the LED lamp. This heat sink is projected in the direction of light emission from the LED lamp, spaced from the power supply unit, and surrounds the power supply unit.

[0163] In a specific embodiment, the light source board 20 is connected to the bottom plate 15 of the base 1 via a fastener 201. The bottom plate 15 of the base 1 is provided with a through hole for the fastener 201 to pass through. The through hole is provided with a first sealing ring 202 that is sleeved on the fastener 201. The first sealing ring 202 can be a rubber ring. The light source board 20 and the bottom plate 15 of the base 1 are tightly connected together via the fastener 201. The light source board 20 is basically attached to the bottom plate 15. In this way, the heat of the light source part 2 is quickly transferred to the base 1, and then the heat is quickly dissipated after being taken away by the gas flow, thereby accelerating the cooling speed of the LED lamp and further improving the service life of the LED lamp. The first sealing ring 202 is sleeved on the fastener 201 to improve the sealing between the fastener 201 and the through hole, thereby preventing external water vapor from penetrating through the through hole and affecting the service life of the lamp beads or causing a short circuit in the electronic components on the light source board 20. Referring to Figure 23 , the first sealing ring 202 preferably employs a riveted structure, which further enhances the seal between the fastener 201 and the through-hole, achieving a sealed and waterproof LED lamp, such as achieving IP66 waterproof rating, suitable for use in humid environments. The fastener 201 may be a screw or bolt, etc., and there may be multiple fasteners 201. In this embodiment, there are three fasteners 201.

[0164] In another specific embodiment, an adhesive (not shown) is provided between the light source board 20 and the bottom plate 15 of the base 1. The light source board 20 is bonded to the bottom plate 15 of the base 1 by the adhesive. The adhesive is preferably a thermally conductive adhesive. The thermally conductive adhesive has good thermal conductivity and can quickly transfer heat from the light source unit 2 to the base 1. The heat is then carried away by the gas flow and quickly dissipated, thereby accelerating the cooling rate of the LED lamp and further increasing the service life of the LED lamp. The thermally conductive adhesive can be a composite colloid in which a certain amount of thermally conductive particles are mixed into the adhesive material.

[0165] As a preferred embodiment, part of the structure of the cover plate 420 passes through the bottom plate 15 and is located in the accommodating space of the base 1, and the lampshade 3 is detachably connected to the bottom plate 15. Specifically, referring to Figure 18A, the bottom plate 15 of the base 1 has a first card slot 152 and a second card slot 153. Referring to Figure 19, a first buckle 310 is provided on the lampshade 3, and the first buckle 310 of the lampshade 3 is locked in the first card slot 152 to connect the lampshade 3 to the base 1. Through the first buckle 310 and the first card slot 152, the lampshade 3 and the base 1 can be quickly installed and quickly disassembled, which is convenient for operation. Referring to Figure 20A, a second buckle 421 is provided on the cover plate 420, and the second buckle 421 is locked in the second card slot 153 to connect the cover plate 420 to the base 1. Through the second buckle 421 and the second card slot 153 structure, the cover plate 420 and the base 1 can be quickly installed and quickly disassembled, which is convenient for operation. Preferably, the light source unit 2 further includes a second sealing ring 370, which is located between the lampshade 3 and the bottom plate 15 of the base 1. The second sealing ring 370 forms a sealed space between the lampshade 3 and the bottom plate 15 of the base 1, preventing the ingress of external moisture, thereby better protecting the LED lamp beads and increasing the service life and reliability of the LED lamp.

[0166] Referring to Figure 19, the lampshade 3 is also provided with a positioning post 320, and the bottom plate 15 of the base 1 and the cover plate 420 are provided with corresponding positioning holes 422. The positioning holes 422 are used to allow the positioning post 320 to pass through so that the lampshade 3 and the cover plate 420 are fixed to the base 1. Specifically, the positioning post 320 can be set around the lampshade 3, or it can be connected to the lampshade 3 through a connecting portion. The connecting portion can be made of a deformable material or a non-deformable material. The connecting portion is preferably made of a deformable material. As a preferred embodiment, the positioning post 320 is an elastomer, and the free end of the positioning post 320 has a stop portion 330. When the positioning post 320 passes through the positioning hole 422, the stop portion 330 of the positioning post 320 first shrinks and then expands so that the stop portion 330 is stuck in the positioning hole 422. Through the interaction between the positioning post 320 and the positioning hole 422, the lampshade 3 and the cover plate 420 can be further fixed to the base 1.

[0167] In a specific embodiment, the lampshade 3 has an incident surface and an exit surface, and the lampshade 3 acts as an adjustment portion to adjust the light output. Referring to Figures 21 and 22, a plurality of annular protrusions 340 are provided on the incident surface and / or the exit surface. The plurality of annular protrusions 340 are distributed at intervals along the radial direction of the lampshade 3. Each annular protrusion 340 includes a plurality of protrusion segments 3401. The adjacent two protrusion segments 3401 of each annular protrusion 340 are staggered in the radial direction of the lampshade 3. In other words, the adjacent two protrusion segments 3401 of each annular protrusion 340 are staggered. The distances between the centers of the lampshade 3 are different, wherein the even-numbered raised segments 3401 of each annular protrusion 340 can be located on the same arc, and the odd-numbered raised segments 3401 of each annular protrusion 340 can be located on the same arc. Rotating the lampshade 3 changes the position between the annular protrusion 340 and the lamp bead (i.e., the LED light-emitting body), so that the light emitted by the lamp bead changes the angle of light emission from the lampshade 3, thereby changing the light emission effect of the LED lamp, for example, a focusing effect or a light diffusion effect, to meet the use of different application scenarios. The multiple raised segments 3401 of the annular protrusion 340 are provided with a light effect surface along the circumference of the lampshade 3, as shown in Figure 21, a light effect surface 350 and a light effect surface 360 ​​corresponding to the light effect surface 350, wherein the light effect surface 350 and the light effect surface 360 ​​form a certain angle with the horizontal plane (the horizontal plane where the LED lamp bead is located). For example, in some embodiments, the angle between the light effect surface 350 and the light effect surface 360 ​​and the horizontal plane is controlled between 10° and 150°, so that the light emitted by the LED lamp beads can undergo specific light conversion on the light effect surface 350 and the light effect surface 360, such as reflection, refraction, scattering, light convergence, etc.

[0168] If the lampshade 3 is rotated by a certain angle, the distance and angle between the light effect surface 350 and the light effect surface 360 ​​will change. After reflection and refraction, the overall light output angle of the lamp will change. For example, the light output angle can vary between 30° and 120°, 45° and 90°, etc.

[0169] In some embodiments, a pointer can be set on the lampshade 3 and a corresponding light output angle can be set on the light source board 20. That is, after the pointer of the lampshade 3 is rotated to the corresponding light output angle, the light output angle of the lamp is adjusted to the light output angle corresponding to the scale, which is convenient for operation.

[0170] In some embodiments, when the LED lamp bead is located in the middle of the gap between the corresponding raised section 3401 in the annular protrusion 340, the light output angle of the lamp is the smallest; when the LED lamp bead is close to the corresponding raised section 3401 of the annular protrusion 340, the light output angle of the lamp is the largest. As shown in Figures 24A to 25B, in some embodiments of the present invention, under certain conditions, the maximum light output angle is set to 90° and the minimum light output angle is 45°. Figure 24A shows the light output angle under the condition of 45°, and Figure 24B shows the light output effect under the condition of 45°. At this time, the light is concentrated toward the center area of ​​the lamp, and there is a higher illumination directly below or in the center area of ​​the lamp. It is suitable for use in scenarios that require high illumination and can clearly see things, such as some situations such as picking goods and observing colors. As shown in Figure 25A, this is the light pattern under the condition of a light output angle of 90°, and Figure 24B is the light effect diagram under the condition of a light output angle of 90°. At this time, the light is divergent and has a wider lighting range. It is suitable for some wide environments that do not require too high illumination, such as some wide transportation roads.

[0171] In some embodiments, the positioning column 320 and the stopper 330 may be eliminated to increase the adjustment range of the lampshade 3 .

[0172] In one embodiment, referring to FIG. 17 , the power module 40 includes a housing 410 , a driving power supply (not shown), and an adjustment switch 411 . The housing 410 has a chamber for accommodating the driving power supply, which is electrically connected to the light source panel 20 . The adjustment switch 411 is connected to the driving power supply and partially exposed from the housing 410 . The adjustment switch 411 is used to control the driving power supply. The adjustment switch 411 can be configured with color temperature adjustment and power adjustment. The color temperature adjustment can have multiple specifications, and the power adjustment can also have multiple specifications. There are three color temperature adjustment options, for example: CW (cool white), NW (warm white), and WW (white). Among them, the color temperature of NW (warm white) is around 3000K, the color temperature of WW (white) is around 4000K, and the color temperature of CW (cool white) is generally above 5000K. There are three power adjustment options, for example: 150W, 200W, and 250W, but the power is not limited to these three and can be adjusted according to actual needs. In this way, the LED lamp can have nine different modes of brightness and color temperature to meet the needs of different applications. The power module 40 also includes an auxiliary power supply (not shown) and a wireless control device 412, wherein the auxiliary power supply can have the function of adjusting the external environmental access power supply (such as the mains), such as adjusting the current and voltage, so that the auxiliary power supply can use wireless control devices of different specifications. The auxiliary power supply supplies power to the wireless control device 412, and the wireless control device 412 is used to control the driving power supply. The wireless control device 412 can be connected to an intelligent module, such as Bluetooth, to achieve intelligent control, facilitate the switching of different working modes of the LED lamp or remote lighting, etc., so that the LED lamp has Internet of Things functions.

[0173] In order to facilitate the installation of the LED lamp and the external environment, referring to Figure 16A, the LED lamp can also include a hook 9, one end of which is connected to the power supply unit 4. The hook 9 can be connected to the power supply unit 4 by a threaded connection, which is convenient for installation and disassembly.

[0174] In some embodiments, the auxiliary power supply also has a certain power storage function, so that the lamp can be used for a period of time in the event of a power outage. For example, in the event of a power outage, the lamp can be lit in low power mode for a longer period of time to serve as an emergency power supply.

[0175] Please refer to Figures 26A, 26B, and 26C, which are three-dimensional views of an LED lamp according to an embodiment of the present invention from different perspectives. As shown in the figures, the LED lamp 100 includes a base 1, which is the main structure of the LED lamp 100 and is generally circular, basin-shaped. The base 1 includes a bottom plate 15 and side walls 14 disposed around the bottom plate 15. The side walls 14 surround the bottom plate 15 to form an accommodating space. A light source unit 2 (not shown) is disposed within the accommodating space. The height of the light source unit 2 does not exceed the height of the side walls 14 (or the thickness of the LED lamp), that is, the height of the light source unit 2 is less than or equal to the height of the side walls 14. In other words, the height (or thickness) of the side walls 14 in a direction perpendicular to the bottom plate 15 is greater than or equal to the height (or thickness) of the light source unit 2 in a direction perpendicular to the bottom plate 15. The outer surface of the base plate 15 also features an integrally formed strip-shaped protrusion 12, or rather, a groove 154 formed on the inner surface of the base plate 15 (i.e., within the accommodating space). In one embodiment, the strip-shaped protrusion 12 is a spiral structure, or a vortex structure, also known as a mosquito coil-like structure. The radius of the spiral gradually increases from the center outward, meaning the radius of the inner ring structure is smaller than the radius of the outer ring structure. A accommodating portion 6 is provided at the center of the base plate 15, with the strip-shaped protrusion 12 surrounding it. This accommodating portion 6 is used to accommodate the power supply unit 4 (not shown). Specifically, the power supply unit 4 is located within the accommodating portion, and the accommodating portion 6 has a raised thickness on the outer surface of the base plate 15. A hanging assembly 9 is also provided on the accommodating portion 6, secured to the accommodating portion 6 via a fixing structure. More specifically, the hanging assembly 9 is provided on the accommodating portion 6 and located on the outer surface of the base plate 15. Referring to FIG26B , the accommodating portion 6 further includes a protrusion protruding into the accommodating space, and the protrusion is at least partially or completely accommodated in the accommodating space. The LED lamp 100 further includes a lampshade 3 disposed on the bottom plate 15 and located in the accommodating space. The shape of the lampshade 3 is the same as the strip-shaped protrusion 12 in FIG26A . The lampshade 3 protrudes in the light-emitting direction of the LED lamp (or the extension direction of the side wall 14) and can completely cover (or cover) the groove 154. The light source portion 2 is disposed in the groove 154. The lampshade 3 is disposed on the light source portion 2, completely covering the groove 154 and protruding in the light-emitting direction of the LED lamp. The lampshade 3 is fixed to the bottom plate 15 and is covered in the groove 154 to form a relatively closed light source accommodating space for accommodating the light source portion 2 (not shown in FIG26A and FIG21B ). The groove 154 and the innermost end of the lampshade 3 (the end of the vortex structure close to the accommodating portion 6 ) extend to the accommodating portion 6 and are at least partially engaged with the accommodating portion 6 .

[0176] Please refer to Figures 27A and 27B. Figure 27A is an exploded schematic diagram of an LED lamp in one embodiment of the present invention, and Figure 27B is an exploded schematic diagram of an LED lamp in one embodiment of the present invention from another perspective. As shown in the figures, the accommodating portion 6 includes an upper accommodating portion cover 64 and a lower accommodating portion cover 65. The upper accommodating portion cover 64 is the raised portion of the accommodating portion 6 on the outer surface of the base plate 15. The lower accommodating portion cover 65 is the raised portion of the accommodating portion 6 that protrudes into the accommodating space. The upper accommodating portion cover 64 can be integrally stamped or spin-formed on the base plate 15, or it can be separately formed and then fixed to the base plate 15. In this embodiment, the upper accommodating portion cover 64 is integrally stamped and formed on the base plate 15, while the lower accommodating portion cover 65 is independently formed and then fixed to the base 1, or in other words, the base plate 15.

[0177] As shown in Figures 27A and 22B, the LED lamp also includes a light source portion 2. The shape of the light source portion 2 is the same as that of the groove 154 or the lampshade 3, but the overall structure is smaller than the groove 154 or the lampshade 3. In other words, the light source portion 2 can be completely accommodated in the light source accommodation space formed by the lampshade 3 and the groove 154. Furthermore, the light source portion 2 is at least partially disposed on the surface of the groove 154 parallel to the bottom plate 15. As shown in Figure 27B, the lampshade 3 has a groove structure formed by protruding in the direction of light output of the LED lamp. In other words, it is low in the middle and high on both sides, or in other words, it is flat in the middle and curved on both sides to form a groove structure. The lampshade 3 is made of a translucent material such as glass or PC. The groove structure of the lampshade 3 can create an optical effect similar to a lens, that is, the lampshade 3 forms a lens structure. In this embodiment, the lampshade 3 forms a convex lens structure, which acts as a light diffuser, making the light output of the LED lamp more uniform while reducing the graininess of the light output of the LED lamp.

[0178] In conjunction with Figures 26A and 27B , it can be seen that at least one cover through-hole 641 is provided on the upper cover 64 of the accommodating portion. In this embodiment of the present invention, there are two cover through-holes 641, each of which is provided on the side wall of the upper cover 64. The cover through-holes 641 located on the side wall can effectively prevent dust or water from entering the interior of the LED lamp during normal use and affecting the operation of the LED lamp. In some embodiments, the cover through-hole 641 can be used as a channel for wires to pass through, connecting an external power source to the power supply unit 4 of the LED lamp. The cover through-hole 641 also plays a role in heat dissipation, allowing the gas inside the accommodating portion 6 to exchange with the gas in the external environment, thereby improving the heat dissipation efficiency of the accommodating portion 6. Therefore, the cover through-hole 641 can also be referred to as a wire through-hole or a heat dissipation through-hole (channel).

[0179] Please refer to Figure 28, which is a schematic diagram of the light source unit in one embodiment of the present invention. As shown in the figure, the light source unit 2 includes a light source board 20 and an LED light strip 21 disposed on the light source board 20, wherein the LED light strip 21 is composed of a plurality of LED light-emitting bodies 211 arranged in an array. The LED light-emitting bodies 211 can be LED lamp beads or LED chips. The light source board 20 has a vortex structure similar to the groove 154 and the lampshade 3. At the end of the innermost circle of the vortex, that is, the end close to the accommodating portion 6, there is a light source board electrical connection end 203 along the radial direction of the vortex. The light source board electrical connection end 203 extends at least partially into the internal space of the accommodating portion 6 and is connected and conductive to the power supply unit 4 (not shown) inside the accommodating portion 6. In this embodiment, two rows of LED light-emitting bodies 211 are provided on the light source board 20 along its extension direction. The two rows of LED light-emitting bodies 211 are arranged in a row along the radial direction of the light source board 20, that is, the two opposite LED light-emitting bodies 211 are arranged along the same radial straight line, and the LED light-emitting bodies 211 change with the curvature of the light source board 20, and their angles are also slightly deflected with the curvature of the light source board 20, that is, in the installation area where each LED light-emitting body 211 is located, the LED light-emitting body 211 has two perpendicular sides, one of which is tangent to the curved side of the light source board 20 in the area where the LED light-emitting body 211 is located, and the other side is parallel to the radius of the curved segment of the area, so that the LED light-emitting bodies 211 are evenly distributed along the light source board 211, and the light output is also evenly divergent along the curvature of the light source board 211, and the overall light output effect is uniform, without obvious bright and dark areas.

[0180] Please refer to Figure 29, which is a front view of the light source part 2 in an embodiment of the present invention. In the radial direction of the LED lamp, the light source board 20 is a vortex structure with a gradually increasing radius, which has a vortex structure. Any part of the vortex includes an inner side and an outer side, wherein the inner side close to the center (or the center of the circle) is called the inner circle, and the outer side away from the center of the circle is called the outer circle. The LED light-emitting body located in the inner circle of the light source board 20 is called the LED light-emitting body 211a, and the LED light-emitting body relative to the outer circle is called the LED light-emitting body 211b. The closest distance between the inner circle LED light-emitting body 211a and the corresponding LED light-emitting body 211b of the adjacent outer circle is L1, and the farthest distance is L2. That is, the light source board is a vortex structure with a gradually increasing radius. In the adjacent vortex structures in the same radial direction, the closest distance between the LED light-emitting bodies is L1, the farthest distance is L2, and 1.5L1≤L2≤3L1. This ensures that there are no blank areas where the LED light-emitting bodies 211 are set on the inner circle and the outer circle in the same radial direction of the light source board 20, and there are sufficient light-emitting overlapping areas of the LED light-emitting bodies 211 to avoid the appearance of obvious dark areas in the areas where the LED light-emitting bodies are not set on the inner circle and the adjacent outer circle of the light source board 20, and the light overlapping area accounts for at least 50% or more of the blank area.

[0181] Please refer to Figure 30, which illustrates a schematic cross-sectional view of an LED lamp along the height (thickness) direction in accordance with one embodiment of the present invention. As shown, the strip-shaped protrusion 12 forms a groove 154 at a height difference relative to the base plate 15, thereby increasing the surface area of ​​the entire base plate 15 and improving its heat dissipation capacity. The lampshade 3 protrudes in the direction of light emission from the LED lamp, and together with the groove 154, forms a tubular, enclosed space for accommodating the light source 2. The light source 2 is positioned within the groove 154, with the strip-shaped protrusion 12 protruding relative to the base plate 15 to form a groove structure that facilitates positioning of the light source 2 and improves installation efficiency. A hanging support assembly 9 is provided on the upper cover 64 of the accommodating portion. The hanging support assembly 9 includes a threaded portion 91 that passes through the upper cover 64 and screws into the interior of the accommodating portion 6, securing the hanging support assembly 9 to the accommodating portion 6. The light source board connection end 203 extends radially into the interior of the accommodating portion 6.

[0182] Please refer to Figure 31, which is an enlarged schematic diagram of point C in Figure 30. As shown, the light source unit 2 is attached to the surface of the groove 154 parallel to the bottom plate 15, and the light source unit 2 is accommodated in the groove 154. The end of the accommodating portion lower cover 65, which is close to the bottom plate 15, is bent outward to form a lower cover bent portion 651. This lower cover bent portion 651 is parallel to the bottom plate 15. During assembly of the LED lamp, the lower cover bent portion 651 is attached to the bottom plate 15, and at least a portion of the lampshade 3 covers the lower cover bent portion 651. In other words, the lower cover bent portion 651 is pressed against the bottom plate 15, and the lampshade 3 is fixed. This fixes the lower cover bent portion 651, thereby fixing the accommodating portion lower cover. In other words, the lampshade 3 and the bottom plate 15 clamp the lower cover bent portion 651. In other words, the lampshade 3 and the bottom plate 15 clamp at least a portion of the accommodating portion lower cover 65. This design can simplify the assembly of LED lamps to a certain extent, improve production efficiency, and save costs (such as the cost of fixing the lower cover 65 of the accommodating portion with glue, screws, welding, etc.).

[0183] In one embodiment, the outer surface of the lampshade 3 (the surface away from the light source portion 2) and the outer surface of the accommodating portion 65 both have a light reflection function. After the light emitted by the light source portion 2 passes through the lampshade 3, at least part of it can be reflected on the outer surface of the lampshade 3 and the outer surface of the lower cover 65 of the accommodating portion and then emitted, avoiding the gap between the annular structure of the lampshade 3, and the gap between the lampshade 3 and the lower cover 65 of the accommodating portion forms a dark area.

[0184] In one embodiment of the present invention, the outer surface of the lampshade 3 and the outer surface of the accommodating portion lower cover 65 realize the light reflection function through their material properties.

[0185] In another embodiment of the present invention, the outer surface of the lampshade 3 and the outer surface of the accommodating portion lower cover 65 realize the light reflection function by means of additional coating or plating.

[0186] In one embodiment of the present invention, the two columns of LED light strips 21 on the light source board 20 are connected in series with each other, and the positive pole and negative pole of the light source board 20 are both arranged at the light source board electrical connection end 203 (or a positive pole in one column of LED light strips 21 and a negative pole in another column of LED light strips 21 are arranged at the light source board electrical connection end 203), that is, the positive pole and negative pole of the light source board 20 are arranged at the same end. Combined with Figures 29 and 30, the light source board electrical connection end 203 extends to the inside of the accommodating portion 6 and is connected to the power supply part 4 to achieve electrical conductivity, that is, the wire connection only needs to be completed at the light source board electrical connection end 203, and there is no need to connect the wires at the head and tail ends of the light source board 20 to realize a conductive loop. The input and output ends of the current loop inside the light source board 20 are both located at the light source board electrical connection end 203, thereby simplifying the wiring process and improving production efficiency.

[0187] Of course, in another embodiment of the present invention, the two columns of LED light strips 21 on the light source board 20 may be connected in parallel.

[0188] In the present invention, the above features can be arranged and combined in any manner and used to improve LED lamps.
