Description

An LED lighting fixture Technical Field

[0001] This invention relates to the field of lighting technology, and more particularly to an LED lighting fixture. Background Technology

[0002] LED lights are widely used in various places due to their convenient 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 advantages such as long life, high efficiency and energy saving, and green environmental protection.

[0003] Existing LED high bay lights generally consist of a luminaire body and an LED light source. The main difference between LED high bay lights and household LED lights is that the power of LED high bay lights is much greater than that of household LED lights. The former typically has a power of 50W to 200W, while ordinary household LED lights generally have a power of no more than 20W. Their structures also differ significantly. High bay lights usually require excellent heat dissipation and light emission performance.

[0004] Existing LED lighting fixtures generally consist of a fixture body and an HID light source. The heat sink for the HID light source is typically made using aluminum die casting. However, aluminum die casting results in problems such as large heat sink volume, heavy weight, and uneven heat sink thickness.

[0005] Heat sinks are used to quickly dissipate the heat generated by LED lights during operation, preventing heat buildup inside the LED lights from affecting normal operation. However, heat sinks generally increase or occupy the volume of the lights, which can have a certain impact on the packaging and transportation of the lights.

[0006] In existing LED lighting fixtures, the light emission direction can only be fixed at a certain angle. When the environment changes (e.g., the installation height or installation angle changes), it is impossible to produce beam angles of different angles. As a result, the original LED lighting fixtures cannot meet or fully meet the current installation environment, and the adaptability of LED lighting fixtures cannot meet customer needs.

[0007] In summary, given the shortcomings and defects of existing LED lighting fixtures, how to design LED lighting fixtures to improve material utilization and reduce weight are technical problems that urgently need to be solved by those skilled in the art. Summary of the Invention

[0062] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the 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. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of the present invention. Terms such as "axial direction," "above," and "below" used below are for the purpose of more clearly indicating structural positional relationships and are not intended to limit the present invention. In this invention, "vertical," "horizontal," and "parallel" are defined as including cases within ±10% of the standard definitions. For example, vertical usually refers to an angle of 90 degrees relative to a baseline, but in this invention, vertical refers to cases including those within 80 to 100 degrees.

[0063] Figures 1 and 7 show an LED lamp according to an embodiment of the present invention. Figure 1 is an exploded view of an LED lamp according to an embodiment of the present invention. The LED lamp includes a base 1 and a light source 2. The light source 2 is disposed on the base 1.

[0064] The light source unit 2 includes a light-emitting unit 21 and a light-emitting unit 22. The light-emitting unit 22 covers the light-emitting side of the light-emitting unit 21. The light emitted by the light-emitting unit 21 passes through the light-emitting unit 22 and is emitted from the LED lamp. The light-emitting unit 21 is disposed between the base 1 and the light-emitting unit 22. In other words, the base 1 and the light-emitting unit 22 form a first receiving space, and the light-emitting unit 21 is disposed within the first receiving space.

[0065] The light-emitting part 21 includes a light source plate 211 and a plurality of LED beads 212. The LED beads 212 are disposed on the light source plate 211. The light source plate 211 may be ring-shaped. The LED beads 212 are disposed on the light source plate 211 and are distributed in a ring. The LED beads 212 may include one or more light source groups. The multiple light source groups may be arranged in a ring, and the rings of the multiple light source groups may have the same center. The LED beads 212 on each light source group can emit light of the same or different color temperatures. When LED beads 212 of different color temperatures are set, the light output of the LED lamp can be diversified. In this embodiment, six light source groups are included, and the six light source groups are arranged in concentric rings.

[0066] The light-emitting part 22 includes a light-processing component 222 and is disposed over the light-emitting side of the light-emitting part 21. The light-processing component 222 may be annular. The light-processing component 222 may include a lens, so that the light emitted from the light-emitting part 21 is emitted after passing through the light-processing component 222. The light-processing component 222 is adapted to change the light path, thereby controlling the light emission angle of the LED lamp. Furthermore, the relative position of the light-processing component 222 and the light-emitting part 21 of the LED lamp can change, that is, the light-processing component 222 and the light-emitting part 21 can move relative to each other, so that the light emission angle of the LED lamp can be adjusted as needed during the use of the LED lamp. Specifically, the relative position of the light-processing component 222 and the light-emitting part 21 can be changed by rotating and / or adjusting the light-processing component 222 up and down. That is, the light-processing component 222 and the light-emitting part 21 are adapted to rotate relative to each other and / or move up and down.

[0067] Figure 7 is an exploded view of the LED lamp in an embodiment of the present invention. As shown in Figure 7, the light processing component 222 further includes an adjustment component 2222. The adjustment component 2222 is disposed on the light processing component 222. Further, the adjustment component 2222 can be disposed on the outer periphery of the light processing component 222, so that by tossing / rotating the adjustment component 2222, the relative position of the lamp bead 212 and the lens changes, thereby adjusting the light emission angle.

[0068] In other words, when the light processing component 222 and the light-emitting part 21 of the LED lamp are in a first relative position, the LED lamp has a first light emission angle. After adjusting the adjustment component 2222, the light processing component 222 and the light-emitting part 21 are in a second relative position and the LED lamp has a second light emission angle. The first relative position is different from the second relative position, and the first light emission angle is different from the second light emission angle.

[0069] The light-emitting part 22 may further include a light-emitting component 221, which is mounted on and connected to the base 1. The light-emitting component 221 and the base 1 can be connected by screws, clips, or other means. The light-emitting component 221 is made of a light-transmitting material, ensuring that the light emitted by the light-emitting part 21 can pass through the light-emitting component 221 and be emitted from the LED lamp, thereby reducing light loss and improving the conversion efficiency between electrical energy and light energy. Furthermore, the light-emitting component 221 may have a frosted or matte finish, thereby reducing the graininess of the LED beads 212.

[0070] The light-emitting component 221 can be disposed outside the light-processing component 222. In other words, the light-processing component 222 can be disposed between the light-emitting component 221 and the light-emitting part 21. That is, the light emitted by the light-emitting part 21 passes through the light-processing component 222, then through the light-emitting component 221, and is emitted from the LED lamp.

[0071] Figure 2 is a cross-sectional view of the LED lamp in this embodiment, and Figure 3 is an enlarged view of point D in Figure 2. Referring to Figure 3, the light processing component 222 includes a lens 2221. The lens 2221 can be a continuous protrusion structure on the surface of the light processing component 222 facing the light emitting component 221, and the lens 2221 covers the light emitting side of the lamp bead 212. Figure 5 is a front view of the light emitting surface of the light processing component 222. As shown in Figures 3 and 5, the lens 2221 is arranged in a ring shape and has a certain thickness. The light processing component 222 may include multiple lenses 2221, which have different radii and are arranged in a concentric circle. In other embodiments, the lens 2221 may also be arranged in a spiral. For example, the width of the lens 2221 changes with the position of the lens on the spiral, that is, different positions on the spiral have different lens widths, and different lens widths correspond to different lens surfaces.

[0072] Referring to Figures 1 and 3, the light processing component 222 of the LED lamp in this embodiment includes a connecting portion 2225. The connecting portion 2225 is connected and fixed to the base 1. In other words, the light processing component 222 can be connected and fixed to the base 1 through the connecting portion 2225. The connecting portion 2225 may be perpendicular or substantially perpendicular to the light-emitting surface and extends toward the side away from the light-emitting surface. That is, the connecting portion 2225 extends toward the base 1. The connecting portion 2225 may be provided at the edge of the light processing component 222.

[0073] Figure 4 is an enlarged view of point C in Figure 1. Referring to Figures 1, 3, and 4, the LED lamp in this embodiment further includes an adjustment unit 6. The adjustment unit 6 is connected to the connecting part 2225 of the light processing component 222. The adjustment unit 6 can move up and down in the height direction (axial direction or thickness direction of the LED lamp). This can cause the connecting part 2225 to move up and down in the height direction (axial direction of the LED lamp). This allows the light processing component 222 to move in the height direction (axial direction of the LED lamp), changing the vertical distance between the light processing component 222 and the LED bead 212 of the light-emitting part 21, thereby changing the light emission angle and adjusting the light emission. In other words, the relative position of the light processing component 222 and the light-emitting part 21 is movable, thereby adjusting the light emission angle. Specifically, the distance between the light processing component 222 and the light-emitting component 221 in the height direction of the LED lamp can be changed. In another embodiment, the adjustment unit 6 is connected to the connecting part 2225 of the light processing component 222. The adjustment unit 6 can move back and forth in the light emission direction of the LED lamp. In turn, it can drive the connecting unit 2225 to move back and forth in the light emission direction of the LED lamp as well.

[0074] The base 1 has an opening 14, which may be disposed on the side of the base 1. An adjustment part 6 is disposed within the opening 14. Further, the opening 14 may include a first opening 141, in which the adjustment part 6 is at least partially engaged.

[0075] The adjusting part 6 includes a first adjusting part 61 and a second adjusting part 62. The first adjusting part 61 may be at least partially disposed in the second adjusting part 62. Further, the first adjusting part 61 may at least partially penetrate the second adjusting part 62. Specifically, the first adjusting part 61 may include a rod 611, and the second adjusting part 62 may include a hole 621, in which the rod 611 is inserted. The side of the rod 611 facing the hole 621 may have two forks 6111 at its tail end, so that the rod 611 can be easily inserted into the hole 621 by elastic stress. The outer side of the forks 6111 may have protrusions 6112, so that after the rod 611 is inserted into the hole 621, the rebound of the forks 6111 and the lowering of the protrusions 6112 make it difficult for the rod 611 to slip out of the hole 621, thereby improving the stability of the connection between the first adjusting part 61 and the second adjusting part 62.

[0076] The first adjustment part 61 may further include a panel part 612. After the first adjustment part 61 is installed into the opening 14, the panel part 612 abuts against the second adjustment part 62, so that the second adjustment part 62 is locked between the first adjustment part 61 and the housing 1. In order to better fix the second adjustment part 62, the area of ​​the panel part 612 may be larger than the area of ​​the second adjustment part 62, so that the panel part 612 completely covers the second adjustment part 62, increasing the force-bearing area and thus enhancing the stability of the second adjustment part 62.

[0077] The first adjustment unit 61 may further include an operating unit 613. The operating unit 613 is disposed on the panel 612 on the side away from the second adjustment unit 62. By operating the operating unit 613, the first adjustment unit 61 can be moved up and down in the height direction (axial direction of the LED lamp). Furthermore, the second adjustment unit 62 is linked by the lever portion 611 of the first adjustment unit 61, so that the second adjustment unit 62 moves together with the first adjustment unit 61.

[0078] The second adjustment part 62 includes a first limiting member 622. The opening 14 may include a first opening 141, which is located on the side of the opening 14 near the center of the LED lamp. The second adjustment part 62 of the adjustment part 6 is partially engaged in the first opening 141. The limiting effect of the first limiting member 622 prevents the second adjustment part 62 from moving arbitrarily in the first opening 141. Specifically, the first opening 141 may include a second limiting member 1411, and the first limiting member 622 may be engaged in the second limiting member 1411. Specifically, the second limiting member 1411 is a serrated limiting structure, and the first limiting member 622 is a protrusion that can engage with the teeth of the second limiting member 1411. When the first adjustment part 61 moves up and down in the opening 14, the rod 611 drives the second adjustment part 62 to move up and down together, and the first limiting member 622 moves and engages simultaneously between the serrated limiting structures.

[0079] As shown in Figures 2 and 3, the rod portion 611 of the first adjusting part 61 passes through the second adjusting part 62 and is inserted into the connecting part 2225. Therefore, when adjusting the displacement of the first adjusting part 61 in the height direction (axial direction of the LED lamp), the connecting part 2225 of the light processing component 222 moves along with it, causing the light processing component 222 to move in the height direction (axial direction of the LED lamp). Because the light processing component 222 moves in the height direction (axial direction of the LED lamp), the distance between the light processing component 222 and the LED bead 212 changes, thereby adjusting the light output. This embodiment includes two symmetrically designed adjusting parts 6. Through the symmetrical design of the adjusting parts 6, the moving direction of the light processing component 222 can be parallel or approximately parallel to the light output direction of the LED lamp, thus ensuring the light output angle.

[0080] Figures 5 and 6 show a light processing component 222 according to an embodiment of the present invention. In this embodiment, the light processing component 222 includes multiple lenses 2221 with different radii and concentrically arranged. Each lens 2221 may be a protruding structure on the surface of the light processing component 222 facing the light-emitting component 221, and the lens 2221 covers the light-emitting side of the lamp bead 212. As shown in Figure 5, the lens 2221 is arranged in a ring shape and has a certain thickness. As shown in Figures 5 and 6, the lens 2221 may include a first lens 22211 and a second lens 22212, which are alternately arranged. The first lens 22211 and the second lens 22212 have different wall thicknesses, thereby changing the light velocity angle emitted by the light-emitting part 21. The wall thickness of the first lens 22211 is greater than the wall thickness of the second lens 22212. In one embodiment, the light emitted by the light-emitting unit 21 is emitted at a beam angle of 60° after passing through the first lens 22211; the light emitted by the light-emitting unit 21 is emitted at a beam angle of 120° after passing through the second lens 22212. In one embodiment, as shown in FIG1, the lamp bead 212 may include a first lamp bead group 2121 and a second lamp bead group 2122, which are alternately arranged, and the first lens 22211 and the second lens 22212 are respectively covered on the light-emitting side of the first lamp bead group 2121 and the second lamp bead group 2122. In other words, the light emitted by the first lamp bead group 2121 and the second lamp bead group 2122 is emitted from the LED lamp after passing through the first lens 22211 and the second lens 22212, respectively. In this embodiment, the first LED group 2121 and the second LED group 2122 can be lit separately; that is, when the first LED group 2121 is lit, the second LED group 2122 is in a non-lit state; or, when the second LED group 2122 is lit, the first LED group 2121 is in a non-lit state. The first LED group 2121 and the second LED group 2122 can also be lit simultaneously. The first LED group 2121 and the second LED group 2122 emit the same light. The light emitted by the first LED group 2121 is emitted at a beam angle of 60° after passing through the first lens 22211; the light emitted by the second LED group 2122 is emitted at a beam angle of 120° after passing through the second lens 22212. When only the first LED group 2121 is lit, the beam angle of the LED lamp is 60°; when only the second LED group 2122 is lit, the beam angle of the LED lamp is 120°; when both the first LED group 2121 and the second LED group 2122 are lit simultaneously, the beam angle of the LED lamp is 90°. Therefore, the angle and magnitude of the light emitted by the LED lamp can be adjusted by lighting different LED groups. In other embodiments, the first LED group 2121 and the second LED group 2122 can emit light of different color temperatures, thereby further adjusting the color temperature of the emitted light by adjusting the lighting state.

[0081] As shown in Figures 1 and 2, the base 1 may include a bottom 15, which is parallel or substantially parallel to the light-emitting surface. The light source 2 may be disposed on the bottom 15.

[0082] The base 1 may include a heat dissipation component 13. The heat dissipation component 13 may be disposed on the bottom 15. Specifically, the bottom 15 has an inner side and an outer side, the light-emitting part 21 is disposed on the inner side of the bottom 15, and the heat dissipation component 13 is disposed on the outer side of the bottom 15. Specifically, the heat dissipation component 13 consists of multiple radially distributed heat dissipation fins, and the heat dissipation component 13 may be a strip-shaped protrusion. The heat dissipation component 13 increases the heat dissipation area, and there are perforated slots between two adjacent heat dissipation components 13, which further helps to dissipate heat.

[0083] Referring to Figure 1, the LED lamp also includes one or more isolation parts 3, which are made of an elastically deformable material, such as silicone. The isolation part 3 is disposed at the opening 14 of the base 1. The shape of the isolation part 3 is adapted to the opening 14 of the base 1, and the size of the isolation part 3 can be slightly larger than the size of the opening 14, thereby achieving an isolation / waterproofing effect for the LED lamp by inserting the isolation part 3 into the opening 14. When the isolation part 3 is removed from the housing 1, the light processing component 222 can be adjusted through the opening 14. This embodiment includes two openings 14 and two corresponding isolation parts 3, with the two openings 14 symmetrically arranged to facilitate the adjustment of the light processing component 222. The isolation part 3 can isolate moisture from the outside of the LED lamp, thus enabling the LED lamp to achieve a waterproof function.

[0084] As shown in Figure 1, the LED lamp may also include an isolation component 5. The isolation component 5 may be made of insulating materials such as silicone or rubber. In this embodiment, the isolation component 5 is a rubber gasket. The isolation component 5 is disposed between the isolation part 3 and the base 1, thereby further enhancing the sealing and waterproof performance of the LED lamp.

[0085] As shown in Figures 2 and 4, the LED lamp may include a support part 4, which may be made of metal, such as aluminum, iron, or steel. The support part 4 may be disposed on the light-emitting side of the light-emitting member 221, thereby clamping the light-emitting member 221 between the support part 4 and the base 1, thus achieving the effect of fixing the light-emitting member 221. In other words, the light-emitting member 221 may be disposed between the base 1 and the support part 4, and abut against both the base 1 and the support part 4 respectively.

[0086] As shown in Figure 3, the isolation portion 3 may further include one or more protrusions 31, which are disposed on the isolation portion 3 facing the light-emitting surface and / or away from the light-emitting surface. The base 1 includes a contact portion 12, which is disposed on the side away from the center of the base 1. The contact portion 12 may be an extension extending toward the outer edge of the LED lamp. The protrusions 31 are in close contact with the support portion 4 and the contact portion 12 of the base 1, increasing the compression (pressure) of the isolation member 3 to improve the sealing and waterproof performance of the LED lamp. In this embodiment, each isolation portion 3 includes 6 protrusions 31.

[0087] As shown in Figure 2, the LED lamp may further include a power supply unit 7. The power supply unit 7 is disposed on the base 1. The power supply unit 7 can be connected to the base 15. Specifically, the power supply unit 7 is disposed on the side of the base 1 opposite to the light-emitting side. That is, the power supply unit 7 is disposed on the outer side of the base 1. In other words, the power supply unit 7 and the heat dissipation component 13 are disposed on the same side of the base 1. The power supply unit 7 and the base 1 form a second accommodating space 71, and the power supply can be disposed within the second accommodating space 71. The power supply unit 7 can be integrally designed with the base 1, meaning the power supply unit 7 cannot be removed from the base 1, thereby increasing the connection stability between the power supply unit 7 and the base 1. In other embodiments, the power supply unit 7 can also be detachably connected to the base 1, thereby facilitating maintenance, power supply replacement, etc.

[0088] Figures 7-13 show an LED lamp according to another embodiment of the present invention; the same parts will not be described again. The difference between this embodiment and the previous embodiments is that the LED lamp in this embodiment adjusts the light emission angle by rotating the light processing component 222. Figures 7 and 8 are exploded views of an LED lamp according to an embodiment of the present invention, and Figure 9 is a cross-sectional view of the LED lamp in this embodiment. The light-emitting part 22 may include the light processing component 222, which is annular and covers the light-emitting side of the light-emitting part 21. The relative position of the light processing component 222 and the light-emitting part 21 can be changed, thereby adjusting the light emission angle. Specifically, the light processing component 222 is disposed between the light-emitting part 21 and the light-emitting component 221. That is, the light emitted from the light-emitting part 21 passes through the light processing component 222, then through the light-emitting component 221, and is emitted from the LED lamp. Figure 10 is an enlarged view of point A in Figure 9. Referring to Figure 10, the light processing component 222 includes a lens 2221. The lens 2221 can be a continuous protrusion structure on the surface of the light processing component 222 facing the light emitting component 221. The lens 2221 covers the light emitting side of the lamp bead 212. Figure 13 is a front view of the light emitting surface of the light processing component 222. As shown in Figure 13, the lens 2221 is arranged in a single-strand planar spiral shape, and the lens 2221 has a certain thickness. Furthermore, the width of the lens 2221 changes with the different positions of the lens on the spiral, that is, different positions on the spiral have different lens widths, and different lens widths correspond to different lens curvatures. Assuming the width near the tail is D1 and the width in the middle is D2, that is, D1 is not equal to D2. In this embodiment, D1 is less than D2 and / or D3 is less than D2, thereby adjusting the light emission angle by adjusting the positional relationship between the lens 2221 and the lamp bead 212. In other words, the width D3 of the lens 2221 located near the center of the light processing component 222 and the width D1 of the lens 2221 located at the edge of the light processing component 222 are smaller than the width D2 of the lens 2221 located in the middle of the single-strand spiral. Furthermore, the thickness of the lens 2221 in segments D1, D2, and D3 can also be different. Therefore, by rotating the light processing component 222, the distance between the lamp bead 212 and the lens 2221 is changed, or the lens surface corresponding to the lamp bead is changed, thereby altering the light emission angle. In another embodiment of the invention, the lens 2221 can be arranged in a double-strand planar spiral or a multi-strand planar spiral.

[0089] As shown in Figure 13, the light processing component 222 may further include one or more positioning components 2224. The positioning components 2224 may be scales / marks or other markings provided on the outer periphery of the light processing component 222. By confirming the position of the positioning components 2224, the rotation angle of the light processing component 222 can be confirmed.

[0090] As shown in Figure 10, the light processing component 222 further includes an adjustment component 2222. The adjustment component 2222 is disposed on the light processing component 222. Further, the adjustment component 2222 can be disposed on the outer periphery of the light processing component 222, thereby changing the relative position of the lamp bead 212 and the lens by moving / rotating the adjustment component 2222, thus adjusting the light emission angle. Further, the adjustment component 2222 can be toothed on the outer periphery of the light processing component 222.

[0091] As shown in Figures 8 and 10, the light processing component 222 may include a structural reinforcement 2223. The structural reinforcement 2223 may be disposed at the edge of the light processing component 222, thereby improving the structural stability of the light processing component 222 through the action of the structural reinforcement 2223.

[0092] As shown in Figures 7 and 8, the base 1 may include a heat dissipation component 13. The heat dissipation component 13 may be disposed on the bottom 15. The bottom 15 of the base 1 has an inner side and an outer side. The light-emitting part 21 is disposed on the inner side of the bottom 15, and the heat dissipation component 13 is disposed on the outer side of the bottom 15. Specifically, the heat dissipation component 13 consists of multiple radially distributed heat dissipation fins, and the heat dissipation component 13 may be a strip-shaped protrusion. The heat dissipation component 13 increases the heat dissipation area, and adjacent heat dissipation components 13 have a perforated slit, which further helps to dissipate heat.

[0093] Referring to Figures 7 and 8, the LED lamp also includes one or more isolation parts 3, which are made of an elastically deformable material, such as silicone. The base 1 has an opening 14, which can be located on the side of the base 1. The isolation part 3 is located at the opening 14 of the base 1. The shape of the isolation part 3 is adapted to the opening 14 of the base 1, and the size of the isolation part 3 can be slightly larger than the size of the opening 14, thereby achieving an isolation / waterproofing effect for the LED lamp by inserting the isolation part 3 into the opening 14. When the isolation part 3 is removed from the housing 1, the adjustment member 2222 of the light processing member 222 can be adjusted through the opening 14. This embodiment includes two openings 14 and two corresponding isolation parts 3, with the two openings 14 symmetrically arranged to facilitate the adjustment of the adjustment member 2222. The isolation part 3 can isolate moisture from the outside of the LED lamp, thus enabling the LED lamp to achieve a waterproof function.

[0094] Figure 11 is a cross-sectional view of the exploded structure of the LED lamp in this embodiment. As shown in Figures 10 and 11, the LED lamp may include a support part 4, which may be made of metal, such as aluminum, iron, or steel. Because the support part 4 is made of metal, it can be disposed on the outer periphery of the light-emitting component 221, thereby fixing the light-emitting component 221. Furthermore, by providing the support part 4, the strength of the LED lamp can be enhanced. Specifically, the support part 4 can be disposed between the base 1 and the light-emitting component 221, and abuts against both the base 1 and the light-processing component 222.

[0095] As shown in Figure 10, the light-emitting component 221 includes a first limiting part 2211, which is a rib protruding towards the light processing component 222 from near the outer edge of the light-emitting component 221. The first limiting part 2211 contacts and presses against the light processing component 222. Thus, the pressing action of the first limiting part 2211 against the light processing component 222 makes it difficult for the light processing component 222 to move in the height direction (axial direction of the LED lamp) of the LED lamp.

[0096] Figure 12 is an enlarged view of point B in Figure 11. As shown in Figure 12, the base 1 may include a second limiting part 11, which is a rib protruding in the light-emitting direction near the outer edge of the base 1. The second limiting part 11 contacts and presses against the light processing component 222. Thus, through the pressing action of the second limiting part 11 on the light processing component 222, the light processing component 222 is less likely to move in the height direction (axial direction of the LED lamp).

[0097] When the LED lamp includes both the first limiting part 2211 and the second limiting part 11, the first limiting part 2211 and the second limiting part 11 can act on the light processing component 222 at the same time, so that the light processing component 222 is subjected to the forces on both sides, thereby limiting the displacement of the light processing component 222 in the height direction of the LED lamp (the axial direction or thickness direction of the LED lamp), so that the vertical distance between the light processing component 222 and the lamp bead 212 is not easily changed, thereby ensuring that the light emission angle is not easily changed.

[0098] Figures 14-17 show an LED lamp according to an embodiment of the present invention. Figure 14 is a schematic diagram of the back of the LED lamp, and Figure 15 is a schematic diagram of the light-emitting surface of the LED lamp. Referring to Figures 14 and 15, the LED lamp in this embodiment includes a power supply unit 7, which is disposed on a base 1. Further, the base 1 includes a light-emitting side and a back side. The light-emitting side is used for light emission from the LED lamp, and the back side is used for heat dissipation of the LED lamp. The power supply unit 7 is disposed on the back side of the base 1. The light source unit 2 is disposed inside the base 1 and emits light towards the light-emitting side. The power supply unit 7 is electrically connected to the light source unit 2. In this embodiment, the power supply unit 7 is fixed to the base 1 and is detachable. In other embodiments, the power supply unit 7 is fixed to the base 1 and is not detachable, thereby ensuring the stability of the LED lamp and making the power supply connection more stable.

[0099] Referring to Figures 14 and 15, the base 1 may include a bottom 15, which can be connected to the power supply unit 7. The light source unit 2 may be disposed on the bottom 15. The base 1 may also include a first sidewall 16, which is annularly disposed outside the bottom 15 and extends toward the light-emitting side of the LED lamp. The first sidewall 16 may be connected to the light processing member 222 and form a third accommodating space for accommodating the light-emitting unit 21. The base 1 may also include a second sidewall 17, which is annularly disposed outside the first sidewall 16. That is, the second sidewall 17 and the first sidewall 16 may be arranged in concentric rings. The first sidewall 16 and the second sidewall 17 are connected and fixed by a heat dissipation member 13. By providing the second sidewall 17, the heat dissipation area of ​​the LED lamp can be increased, thereby improving the heat dissipation effect. The first sidewall 16 and the second sidewall 17 are connected by the heat dissipation component 13, and one or more heat dissipation holes 18 can be formed between the first sidewall 16 and the second sidewall 17. By setting the heat dissipation holes 18, air convection can be increased and the heat dissipation effect of the LED lamp can be improved.

[0100] Figure 16 is an exploded view of the LED lamp structure in this embodiment, and Figure 17 is a schematic diagram of Figure 16 from different perspectives. The main components and structure of the LED lamp in this embodiment are the same as those in the previous embodiment, the main difference being that the LED lamp in this embodiment also includes a second isolation part 8. The second isolation part 8 in this embodiment is annular and is disposed between the base 1 and the light processing component 222. The second isolation part 8 is made of a material with elastic deformation, such as a silicone ring. Figure 18 is a cross-sectional view of the LED lamp in this embodiment, and Figure 19 is an enlarged view of point F in Figure 18. Specifically, the second isolation part 8 is disposed between the base 1 and the light processing component 222 of the light emitting part 22, thereby forming a sealed space between the base 1 and the light emitting part 22. The light source part 2 is disposed in this sealed space, thereby achieving the effect of isolation / waterproofing. In this embodiment, the LED lamp includes two second isolation parts 8, and the light processing component 222 is annular; one second isolation part 8 is disposed on the outer ring side of the light processing component 222, and the other second isolation part 8 is disposed on the inner ring side of the light processing component 222. As shown in Figure 19, grooves 101 are respectively provided on the outer and inner ring sides of the base 1 relative to the light processing component 222, and the second isolation part 8 is disposed in the groove 101. The light processing component 222 is provided with a stop part 2227 relative to the groove 101 of the base 1, and the stop part 2227 protrudes towards the groove 101. This facilitates pressing the second isolation part 8 into the groove 101, achieving a sealing effect, and ensuring that the second isolation part 8 does not easily slip out of the groove 101. As shown in Figure 19, the light processing component 222 includes an adjustment component 2222. The adjustment component 2222 is connected to the base 1, thereby achieving a fixed connection between the light processing component 222 and the base 1. The adjustment component 2222 can be C-shaped or approximately C-shaped. The base 1 and the light processing component 222 can rotate relative to each other through the connection of the adjustment component 2222.

[0101] Figure 20 is a schematic diagram of the structure of the light processing component 222. As shown in Figure 20, the light processing component 222 may include multiple adjusting components 2222, which may be disposed on the outer and inner peripheral sides of the light processing component 222. Figure 21 is an enlarged view of point H in Figure 20. As shown in Figure 21, the outer peripheral side of the light processing component 222 includes a sidewall 2226. The adjusting component 2222 is C-shaped and forms a receiving groove 22221 with the sidewall 2226. When the base 1 and the light processing component 222 rotate to the required position, the base 1 is disposed in the receiving groove 22221 when it needs to be fixed. The adjusting component 2222 may also include a limiting fitting part 22222, which is in a protruding state. After the base 1 and the light processing component 222 are rotated to the desired position, the limiting fitting part 22222 of the adjusting component 2222 can be locked in the base 1, thereby fixing the relative position of the base 1 and the light processing component 222 and making it difficult for them to rotate relative to each other.

[0102] Figure 22 is a structural schematic diagram of the base 1, and Figure 23 is an enlarged view of point G in Figure 22. As shown in Figures 19, 22, and 23, the base 1 of the LED lamp can be annular. The base 1 may include an inner ring wall 102, which is located on one side near the center of the LED lamp. The base 1 may include one or more third limiting parts 19, which are located on the outer side of the first side wall 16 of the base 1 and / or on the inner ring wall 102. In this embodiment, the base 1 includes multiple third limiting parts 19, which are respectively located on the outer side of the first side wall 16 and on the inner ring wall 102 of the base 1. By providing multiple third limiting parts 19, after the base 1 and the light processing component 222 are rotated to the desired position, the third limiting parts 19 engage with the receiving groove 22221 of the adjusting component 2222, thereby fixing the base 1 and the light processing component 222 to each other. This ensures the stability between the base 1 and the light processing component 222, preventing unnecessary relative rotation between them. A third limiting part 19 is provided on the base 1 and protrudes towards the light processing structure 222. The third limiting part 19 may include a limiting fixing part 191, which may be concave / notch-shaped, allowing the limiting fitting part 22222 of the adjusting component 2222 to be engaged in the limiting fixing part 191, thereby fixing the relative position of the base 1 and the light processing component 222. Furthermore, the third limiting part 19 may also include one or more buffer parts 192, which may be sloped, facilitating the engagement of the limiting fitting part 22222 of the adjusting component 2222 into the limiting fixing part 191. In this embodiment, the third limiting part 19 may be provided with two buffer parts 192, which may be respectively provided on both sides of the limiting and fixing part 191, thereby facilitating the relative rotation of the base 1 and the light processing component 222. The adjusting component 2222 may be provided relative to the third limiting part 19 of the base 1. The limiting fitting part 22222 may protrude toward the limiting and fixing part 191 of the third limiting part 19. After the base 1 and the light processing component 222 rotate to the required position, the limiting fitting part 22222 of the adjusting component 2222 may be engaged in the limiting and fixing part 191, thereby fixing the relative position of the base 1 and the light processing component 222 and preventing necessary relative rotation.

[0103] Figures 24-28 show an LED lamp according to another embodiment of the present invention. Figure 24 is a structural schematic diagram of the LED lamp according to an embodiment of the present invention, and Figure 25 is an enlarged view of point I in Figure 24. In this embodiment, the base 1 includes a fixing part 9, which is used to fix the base 1 and the light source part 2. Specifically, the fixing part 9 is disposed on the back side of the base 1 and on the inner and outer sides of the base 1 and the light source part 2, and clamps the base 1 and the light source part 2. The fixing part 9 is disposed on the back side of the base 1, that is, the side of the base 1 facing away from the light-emitting surface, so as not to affect the light emission of the LED lamp.

[0104] As shown in Figure 25, the fixing part 9 includes a fixing part base 91. The fixing part base 91 is disposed on the back side and outer side of the base 1. The fixing part 9 also includes a first operating part 92, which is at least partially exposed in the fixing part base 91, thereby operating the exposed portion of the fixing part base 91. By operating and controlling the first operating part 92, the fixing part 9 can be adjusted. The fixing part 9 may also include a fixing structure 93, which is used to connect and fix the fixing part base 91 and the first operating part 92.

[0105] Figure 26A is an exploded view of the structure of the fixing part 9 in one embodiment of the present invention. As shown in Figure 26A, the fixing part base 91 may include a first fixing part base 911 and a second fixing part base 912. The first fixing part base 911 is at least pressed onto the second fixing part base 912, and the first fixing part base 911 and the second fixing part base 912 are connected and fixed through the connecting action of the fixing structure 93. By designing the first fixing part base 911 and the second fixing part base 912 as separate parts, the installation of the fixing part 9 can be facilitated. In other embodiments, the fixing part base 91 may also be an integral structure, thereby increasing the stability of the fixing part base 91 structure. In this embodiment, the first fixing part base 911 may be in the shape of a horizontally arranged J, and the long side arm of the J is the first arm 9111. Figures 26B and 26C are structural schematic diagrams of the fixing part 9 in one embodiment of the present invention. As shown in Figures 26B and 26C, the first arm 9111 is in contact with the second fixing part base 912, and the first arm 9111 is at least partially pressed onto the second fixing part base 912. The second fixing base 912 is also horizontally arranged in a J-shape, with the long arm of the J being the second arm 9121. The second arm 9121 contacts the first fixing base 911. Specifically, the second arm 9121 can contact the first arm 9111 of the first fixing base 911. In other words, the first arm 9111 can at least partially press against the second arm 9121.

[0106] As shown in Figure 26A, the first arm 9111 of the first fixing base 911 includes an extension 9112. The extension 9112 is disposed at the end of the first arm 9111 and is used to connect and fix with the second fixing base 912. The second arm 9121 of the second fixing base 912 includes a latching part 9122, which is a protrusion structure disposed on the second arm 9121. Further, the latching part 9122 may be inverted L-shape. The latching part 9122 and the second arm 9121 may form a groove. When the first fixing base 911 and the second fixing base 912 are connected and fixed, the extension 9112 is engaged in the groove formed by the latching part 9122 and the second arm 9121, thereby restricting the relative position of the first fixing base 911 and the second fixing base 912. In other words, in Figure 26C, by engaging the extension 9112 in the groove that can be formed between the latching part 9122 and the second arm 9121, the movement of the first fixing part base 911 in the height direction and the front-back direction of the fixing part 9 can be restricted.

[0107] As shown in Figure 26A, the first arm 9111 of the first fixing base 911 includes a first fixing hole 9114, through which the fixing structure 93 can pass to connect and fix with the second fixing base 912. Specifically, the second arm 9121 of the second fixing base 912 includes a second fixing hole 9124, through which the fixing structure 93 passes sequentially, thereby connecting and fixing the first fixing base 911 and the second fixing base 912. In this embodiment, the fixing structure 93 is a screw / nut or other fixing structure, which applies external force to the first fixing base 911, thereby connecting and fixing the first fixing base 911 and the second fixing base 912. In other embodiments, the fixing structure can also be a snap-fit ​​or other structure, and the first fixing base 911 and the second fixing base 912 can be connected and fixed through snap-fit ​​or other structures. The first fixing base 911 includes a third arm 9115, which is perpendicular or substantially perpendicular to the first arm 9111. One end of the third arm 9115 is connected to the other end of the first arm 9111. The other end of the third arm 9115 also includes a first extension 9116, which is perpendicular or substantially perpendicular to the third arm 9115. In other words, the first extension 9116 is parallel or substantially parallel to the first arm 9111. The second fixing base 921 includes a fourth arm 9125, which is connected to one end of the second arm 9121 and is perpendicular or substantially perpendicular to it. The other end of the fourth arm 9125 also includes a second extension 9126, which is perpendicular or substantially perpendicular to the fourth arm 9125. In other words, the second extension 9126 is parallel or substantially parallel to the second arm 9121. As shown in Figure 26B, after the first fixing base 911 and the second fixing base 921 are connected and fixed, the first arm 9111 and the second arm 9121 are parallel or approximately parallel; the third arm 9115 and the fourth arm 9125 are parallel or approximately parallel; the first extension 9116 and the second extension 9126 are parallel or approximately parallel, and the first extension 9116 and the second extension 9126 are arranged opposite to each other. In other words, the first extension 9116 extends toward the second extension 9126, and the second extension 9126 extends toward the first extension 9116.

[0108] The first arm 9111 of the first fixing base 911 may also include a sliding groove 9113, the sliding groove 9113 being parallel to the extending direction of the first arm 9111. A first fixing hole 9114 is provided at the end of the sliding groove 9113 near the end of the third arm 9115. By providing the sliding groove 9113, the fixing structure 93 can move within the sliding groove 9113 after installation. Furthermore, by moving the fixing structure 93 within the sliding groove 9113, the relative positions of the first fixing base 911 and the second fixing base 912 are changed; that is, the relative distance between the third arm 9115 and the fourth arm 9125 can be changed. This allows the fixing part 9 to be adapted to different LED lighting fixtures.

[0109] The first arm 9111 also includes a second opening 9117. The second opening 9117 is located on the side of the first arm 9111 away from the third arm 9115, that is, the second opening 9117 is located at one end of the first arm 9111 near the extension 9112 and in the extension 9112. The second opening 9117 is not in communication with the sliding groove 9113. The second opening 9117 and the extension 9112 form a U-shape or a generally U-shape.

[0110] The fourth arm 9125 may include a reinforcing rib 91251, which increases the structural strength of the fourth arm 9125.

[0111] As shown in Figure 26A, the fixing part 9 also includes a first operating part 92. The first operating part 92 is an operating handle. The first operating part 92 includes an operating end 921. As shown in Figure 25, the operating end 921 is located on the side near the outer side of the base 1, thereby facilitating operation of the first operating part 92 through the operating end 921. The first operating part 92 may also include a pressing end 922, which may be located at the end relatively away from the outer side of the base 1. The pressing end 922 and the operating end 921 are disposed opposite each other at both ends of the first operating part 92. The pressing end 922 includes a first connecting part 9221, which may be protruding and disposed on both sides of the pressing end 922.

[0112] The second arm 9121 of the second fixing base 912 includes a first recess 9123 and a second recess 91231. The first recess 9123 is located on the side with the latching part 9122 and is recessed towards the second extension 9126. The distance between the first recess 9123 and the fourth arm 9125 is greater than the distance between the latching part 9122 and the fourth arm 9125. The second recess 91231 is located on both sides of the first recess 9123. The first recess 9123 is used to accommodate a portion of the pressing end 922, and the second recess 91231 is used to accommodate the first connecting part 9221.

[0113] As shown in Figures 26A, 26B, and 26C, when the first operating part 92 is connected and fixed to the base 91, the pressing end 922 is at least partially disposed in the first recess 9123, and the first connecting part 9221 is disposed in the second recess 91231. Then, through the pressing action of the first arm 9111, the first connecting part 9221 is confined in the second recess 91231, thereby preventing the pressing end 922 from falling out of the first recess 9123. Furthermore, at least a portion of the first operating part 92 is exposed from the second opening 9117, allowing operation of the first operating part 92 after installation.

[0114] Figure 26D is a schematic diagram of the operation structure of the fixing part 9 in one embodiment of the present invention. As shown in Figure 26D, the first operating part 92 can rotate on the fixing part 9 with the first connecting part 9221 as the rotation axis. Specifically, the operating end 921 can rotate upward, that is, the operating end 921 can rotate in the height direction of the LED lamp in a direction away from the base 912 of the second fixing part.

[0115] Figure 27 is a cross-sectional view of the LED lamp after the power supply unit is removed in an embodiment of the present invention, and Figure 28 is an enlarged view of point J in Figure 27. As shown in Figures 27 and 28, the first fixing base 911 clamps the inner edge of the base 1 and the light processing component 222, and the second fixing base 912 clamps the outer edge of the base 1 and the light processing component 222. When the first fixing base 911 and the second fixing base 912 are fixed to each other by the fixing structure 93, they become fixing parts 9 that can fix the base 1 and the light processing component 222. By operating the first operating part 92, for example, when the operating end 921 rotates and approaches the second arm 9121 of the second fixing base 912, the pressing end 922 can contact the base 1 and exert a force on the base 1, which can press the base 1 and the light processing component 222 together, so that the base 1 and the light processing component 222 are not easily rotated relative to each other or moved in the height direction of the lamp.

[0116] The first operating part 92 may include a protrusion 923. When the first operating part 92 is in a fixed state, the protrusion 923 is at its highest point, i.e., the side furthest from the bottom 15. When the first operating part 92 is in a fixed state, in the height direction of the LED lamp, the vertical distance from the operating end 921 to the protrusion 923 is H1, and the vertical distance from the pressing end 922 to the protrusion 923 is H2, where H1 < H2. This allows the pressing end 922 to exert pressure on the base 1 when the first operating part 92 is in a fixed state. When the operating end 921 rotates to a position close to the outside of the base 1, the base 1 and the light processing structure 222 are clamped together, and their relative positions remain fixed. When the operating end 921 rotates to a position close to the inside of the base 1, the clamping force disappears, and the force between the base 1 and the light processing structure 222 disappears, allowing the base 1 and the light processing structure 222 to rotate or move relative to each other.

[0117] Figures 29-42 show an LED lamp fixture according to another embodiment of the present invention; the same parts will not be described again. The difference between this embodiment and the previous embodiments lies in the way the base 1 and the light-emitting part 22 are fixed in the LED lamp fixture of this embodiment.

[0118] Figure 29 is a schematic diagram of an LED lamp in one embodiment of the present invention, Figure 30 is an exploded view of the LED lamp structure in this embodiment, and Figure 31 is a schematic diagram of Figure 30 from different perspectives. As shown in Figures 29, 30, and 31, the base 1 includes multiple limiting and fixing members 103. Through the limiting and fixing effect of the limiting and fixing members 103, the base 1 and the light-emitting part 22 are kept relatively fixed. There may be one or more limiting and fixing members 103. In this embodiment, there are multiple limiting and fixing members 103.

[0119] Figure 32 is a schematic diagram of the LED lamp in this embodiment as viewed from the light-emitting surface. As shown in Figure 32, the base 1 includes multiple limiting and fixing members 103, which are disposed on the first side wall 16 (outer ring wall) and / or the third side wall (inner ring wall) 102 of the base 1. In this embodiment, the limiting and fixing members 103 are respectively disposed on the first side wall 16 and the third side wall 102 of the base 1. The limiting and fixing members 103 are disposed on the base 1 and at least partially pressed against the light-emitting part 22, thereby limiting the light-emitting part 22 in the height direction of the LED lamp. Specifically, the limiting and fixing members 103 have a certain range of movement in the height direction of the LED lamp, that is, by changing the position of the limiting and fixing members 103 in the height direction of the LED lamp, the relative position of the base 1 and the light-emitting part 22 can be controlled.

[0120] Figure 33 is a schematic diagram of the structure of an LED lamp after the light-emitting part 22 is removed according to an embodiment of the present invention. As shown in Figure 33, the first sidewall 16 of the base 1 includes one or more first protrusions 161 facing the second sidewall 17. A portion of the limiting and fixing member 103 is disposed in the first protrusion 161, thereby fixing the limiting and fixing member 103 relative to the base 1. The third sidewall 102 of the base 1 includes one or more second protrusions 1021 facing the power supply part 7. A portion of the limiting and fixing member 103 is disposed in the second protrusion 1021, thereby fixing the limiting and fixing member 103 relative to the base 1.

[0121] In this embodiment, six first protrusions 161 are included, and the spacing between adjacent first protrusions 161 is the same or approximately the same. Because the limiting and fixing member 103 is disposed on the first protrusion 161, the design of the position of the first protrusion 161 can enhance the even distribution of the force exerted by the limiting and fixing member 103 on the light-emitting part 22, thereby enhancing the stability of the connection and fixation between the light-emitting part 22 and the base 1.

[0122] In this embodiment, three second protrusions 1021 are included, with adjacent second protrusions 1021 having the same or approximately the same spacing. The line connecting any two adjacent second protrusions 1021 forms an equilateral triangle. Because the limiting and fixing member 103 is disposed on the second protrusions 1021, the design of the position of the second protrusions 1021 can enhance the even distribution of the force exerted by the limiting and fixing member 103 on the light-emitting part 22, thereby enhancing the stability of the connection and fixation between the light-emitting part 22 and the base 1.

[0123] Figure 34 is a cross-sectional view of the LED lamp after the power supply part 7 is removed in an embodiment of the present invention, and Figure 35 is an enlarged view of point K in Figure 34. As shown in Figures 34 and 35, the limiting and fixing member 103 can move up and down in the first protrusion 161 in the height direction of the lamp. The light-emitting part 22 includes a light-emitting unit fixing part 223, which is provided on the outer edge side of the light-emitting part 22 and extends toward the outer edge of the light-emitting part 22. When the limiting and fixing member 103 moves toward the light-emitting surface side, the force of the limiting and fixing member 103 on the light-emitting unit fixing part 223 of the light-emitting part 22 is weakened. At this time, the light-emitting part 22 can be rotated. After the light-emitting part 22 is rotated to the required position, the limiting and fixing member 103 is moved toward the bottom 15, thereby strengthening the force of the limiting and fixing member 103 on the light-emitting unit fixing part 223 of the light-emitting part 22, and thus fixing the light-emitting part 22.

[0124] Figure 36 is a cross-sectional view of the LED lamp after the power supply part 7 is removed in an embodiment of the present invention, and Figure 37 is an enlarged view of point L in Figure 36. As shown in Figures 36 and 37, the limiting and fixing member 103 can move up and down in the second protrusion 1021 in the height direction of the lamp. The light-emitting part 22 includes a light-emitting unit fixing part 223, which is provided on the inner edge side of the light-emitting part 22 and extends toward the inner edge of the light-emitting part 22. When the limiting and fixing member 103 moves toward the light-emitting surface side, the force of the limiting and fixing member 103 on the light-emitting unit fixing part 223 of the light-emitting part 22 is weakened. At this time, the light-emitting part 22 can be rotated. After the light-emitting part 22 is rotated to the required position, the limiting and fixing member 103 is moved toward the bottom 15, thereby strengthening the force of the limiting and fixing member 103 on the light-emitting unit fixing part 223 of the light-emitting part 22, thereby fixing the light-emitting part 22.

[0125] Furthermore, the limiting and fixing members 103 in the first protrusion 161 and the second protrusion 1021 can be adjusted simultaneously. For example, by simultaneously moving the limiting and fixing members 103 in the first protrusion 161 and the second protrusion 1021 toward the light-emitting surface, the force exerted by the limiting and fixing members 103 on the inner and outer rings of the light-emitting part 22 is simultaneously reduced, thereby facilitating the rotation of the light-emitting part 22. Alternatively, the limiting and fixing members 103 in the first protrusion 161 and the second protrusion 1021 can be adjusted separately. For example, only the limiting and fixing member 103 in the first protrusion 161 can be moved toward the light-emitting surface without changing the position of the limiting and fixing member 103 in the second protrusion 1021, thus allowing rotation while ensuring that the light-emitting part 22 does not fall out of the LED lamp 100. Conversely, the limiting and fixing member 103 in the second protrusion 1021 can be moved toward the light-emitting surface without changing the position of the limiting and fixing member 103 in the first protrusion 161. This allows rotation while ensuring that the light-emitting part 22 does not fall out of the LED lamp 100.

[0126] As shown in Figures 30, 31, 33, 35, and 37, the LED luminaire may further include a second isolation portion 8. As shown in Figures 35 and 37, the second isolation portion 8 is sandwiched between the base 1 and the light-emitting portion 22. Furthermore, the second isolation portion 8 is sandwiched between the base 1 and the light-emitting portion 22 in the width direction or radial direction of the LED luminaire.

As shown in Figures 36-42, the second isolation part 8 in this embodiment is annular. The second isolation part 8 is made of a material with elastic deformation, such as a silicone ring. Through the isolation function of the second isolation part 8, external moisture and other gases can be prevented from entering the lamp. The second isolation part 8 includes an isolation body part 81. The isolation body part 81 is annular and is disposed on the outer ring side and / or inner ring side of the light emitting part 22.

Further, the isolation reinforcement part 82 is protruding. As shown in Figures 35 and 37, the isolation reinforcement 82 is positioned facing the base 1. By providing the isolation reinforcement 82, the interaction force between the base 1 and the isolation reinforcement 82 can be increased, thereby fixing the relative position of the base 1 and the light-emitting part 22 and preventing necessary relative rotation.

[0128] As shown in Figure 35, the first protrusion 161 includes a third sidewall 1611, and the second isolation portion 8 is sandwiched between the third sidewall 1611 of the base 1 and the light-emitting portion 22.

Further, the light-emitting unit fixing portion 223, the light-emitting unit limiting portion 224, and the third sidewall 1611 can form a fourth accommodating space, within which the second isolation portion 8 is disposed. The isolation body portion 81 contacts the light-emitting unit limiting portion 224. The isolation reinforcement portion 82 is disposed toward and contacts the third sidewall 1611.

[0129] As shown in Figure 37, the base 1 may include a fourth sidewall 107 facing the light-emitting surface, and the second isolation portion 8 is sandwiched between the fourth sidewall 107 and the light-emitting portion 22 of the base 1. The light-emitting unit fixing portion 223 of the light-emitting portion 22 may include a light-emitting unit limiting portion 224, which extends toward the bottom 15. The second isolation portion 8 can be sandwiched between the fourth sidewall 107 of the base 1 and the light-emitting unit limiting portion 224 of the light-emitting portion 22. Further, the light-emitting unit fixing portion 223, the light-emitting unit limiting portion 224, and the fourth sidewall 107 can form a fifth accommodating space, and the second isolation portion 8 is disposed in the fifth accommodating space. The second protrusion 1021 includes a fifth sidewall 10211, and from the axis of the LED lamp outward, the fifth sidewall 10211, the light-emitting unit limiting portion 224, the second isolation portion 8, and the fourth sidewall 107 are arranged sequentially. The isolation body 81 is in contact with the light emission unit limiting part 224. The isolation reinforcement part 82 is disposed toward the fourth side wall 107 and is in contact with the fourth side wall 107.

[0130] In other embodiments (not shown), the second protrusion 1021 includes a fifth sidewall 10211, and the second isolation portion 8 is sandwiched between the fifth sidewall 10211 of the base 1 and the light-emitting portion 22. The light-emitting unit fixing portion 223 of the light-emitting portion 22 may include a light-emitting unit limiting portion 224, which extends toward the bottom 15. The second isolation portion 8 is sandwiched between the fifth sidewall 10211 of the base 1 and the light-emitting unit limiting portion 224 of the light-emitting portion 22.

[0131] Figure 43 is a schematic diagram of the structure of the base 1 of the LED lamp according to an embodiment of the present invention. As shown in Figure 43, the base 1 may include a bottom 15, which is parallel or substantially parallel to the light-emitting surface. The base 1 may include a conductive portion 151, which may be disposed on the bottom 15. Further, the conductive portion 151 may be disposed on the side of the bottom 15 facing away from the light-emitting side. The conductive portion 151 protrudes on the side facing away from the light-emitting side, forming a seventh accommodating space 1510, which can be used to accommodate wires.

[0132] The conductive part 151 may include a conductive port 1511, through which a wire housed in the seventh accommodating space 1510 passes and connects to the power supply part 7 and the light source part 2 respectively. The power supply part 7 and the light source part 2 are electrically connected through the electrical connection of the wire. The conductive part 151 may also include a conductive fixing part 1512, which provides a mechanical connection between the conductive part 151 and the power supply part. Specifically, the conductive fixing part 1512 may be a hole structure. In this embodiment of the invention, the conductive part 151 is a one-time molding design, i.e., it is formed in one step using a mold, eliminating the need for secondary processing of the conductive fixing part 1512, thus effectively reducing material costs.

[0133] Figure 44 is an exploded view of the LED lamp fixture according to an embodiment of the present invention, and Figure 45 is an enlarged view of point O in Figure 44. As shown in Figures 43, 44, and 45, the power supply unit 7 may include a third connecting part 72, which is used to connect and fix with the conductive part 151 of the base 1. In other words, the power supply unit 7 and the base 1 are connected and fixed through the third connecting part 72 and the conductive part 151. The third connecting part 72 includes an arm 721, which is disposed on the side of the power supply unit 7 and extends toward the side away from the power supply unit 7. The arm 721 may include a third opening 7212 facing the base 1. The third opening 7212 is disposed toward the conductive port 1511 of the conductive part 151. When the power supply unit 7 is connected and fixed with the base 1, the third opening 7212 and the conductive port 1511 are connected and engaged to form a closed space. The wires can be connected within the enclosed space, thereby ensuring the electrical connection between the power supply unit 7 and the light source unit 2, while also ensuring the waterproofness of the LED lamp wiring, thus improving the safety performance of the LED lamp.

[0134] The third connecting portion 72 may further include a third fixing portion 722, which may be disposed on the arm portion 721. Further, the third fixing portion 722 may be disposed on the side of the arm portion 721 away from the power supply portion 7. Bolts, screws, and other connecting fasteners 1513 may pass through the third fixing portion 722 of the third connecting portion 72, and then through the conductive fixing portion 1512 of the conductive portion 151, thereby connecting and fixing the third connecting portion 72 to the conductive portion 151.

[0135] Figure 46 is an enlarged view of point P in Figure 44, and Figure 47 is a cross-sectional view of the LED lamp. As shown in Figures 46 and 47, the light processing component 222 of the LED lamp in this embodiment includes a fourth connecting portion 2228. The fourth connecting portion 2228 is connected and fixed to the base 1. In other words, the light processing component 222 can be connected and fixed to the base 1 through the fourth connecting portion 2228. The fourth connecting portion 2228 includes a fourth support portion 22281, which is disposed on the outer ring side of the light processing component 222 and extends toward the side away from the light-emitting side. The fourth support portion 22281 is perpendicular or substantially perpendicular to the bottom 15 of the base 1. The fourth connecting portion 2228 may also include a first engaging portion 22282, which is disposed at the front end of the fourth support portion 22281 and extends toward the outside of the LED lamp. The first engaging portion 22282 may be a chamfered structure for connecting and engaging with the base 1.

[0136] After the LED lamp is assembled, the fourth support portion 22281 is disposed between the first side wall 16 and the second side wall 17 of the base 1. Furthermore, the distance between the fourth support portion 22281 and the first side wall 16 is greater than the distance between the fourth support portion 22281 and the second side wall 17; that is, the fourth support portion 22281 is positioned closer to the second side wall 17 than the first side wall 16. Viewed in cross-section of the LED lamp, the fourth support portion 22281 is parallel or approximately parallel to the second side wall 17.

[0137] The second sidewall 17 includes one or more second engaging portions 171, which are disposed on the side facing the fourth support portion 22281. Further, the second engaging portion 171 may protrude towards the fourth support portion 22281. The second engaging portion 171 is used to connect and engage with the first engaging portion 22282 of the fourth connecting portion 2228. The second engaging portion 171 may be chamfered, that is, the second engaging portion 171 may have a first inclined surface 1711 facing the light emission direction, and its other side is a plane parallel to the bottom 15. The first engaging portion 22282 may have a second inclined surface 22283 facing away from the light emission direction, and its other side is a plane parallel to the bottom 15. Thus, the first inclined surface 1711 of the second engaging portion 171 and the second inclined surface 22283 of the first engaging portion 22282 make the installation of the second engaging portion 171 and the first engaging portion 22282 easier. Furthermore, by aligning the second engaging portion 171 and the first engaging portion 22282 parallel to the plane of the bottom 15, the second engaging portion 171 and the first engaging portion 22282 are less likely to slip off or detach. Moreover, the LED light fixture's light processing component 222 is installed using a snap-fit ​​method, eliminating the need for screws and saving time and labor.
