Description

Technical Field

[0001] The utility model relates to the technical field of lamps, and more specifically, to a directional lighting lamp and a lighting system provided with the directional lighting lamp. Background Art

[0002] Directional lighting lamps generally refer to lamps such as downlights and spotlights. Common existing directional lighting lamps include components such as a lamp body, a rear cover, an optoelectronic component, a lens, and an anti-glare ring; the lamp body has a lamp cavity, and the opening of the lamp cavity is formed at the front end of the lamp body; the rear cover is installed at the rear end of the lamp body; the optoelectronic component is fixed in the lamp cavity by self-tapping screws, and the optoelectronic component is provided with positioning holes; the lens is placed in the lamp cavity, and a positioning foot that cooperates with the positioning hole is provided at one end of the lens close to the light source, and the positioning foot is inserted into the positioning hole; at least a part of the anti-glare ring is located in the lamp cavity, the anti-glare ring is located at the opening of the lamp cavity and is connected to the lamp body, and after the anti-glare ring is assembled with the lamp body, the anti-glare ring presses on the lens to cooperate with the optoelectronic component to clamp and fix the lens; among them, there are usually the following two assembly methods between the rear cover and the lamp body:

[0003] First, a buckle is provided on the rear cover, and a card slot that cooperates with the buckle is provided on the lamp body. When the rear cover and the lamp body are assembled, the buckle and the card slot are snapped and connected.

[0004] Second, a connection hole is provided on the rear cover, and a through hole that cooperates with the connection hole is provided on the lamp body. When connecting, self-tapping threads are processed for the connection hole by passing a self-tapping screw through the through hole, thereby realizing threaded connection with the connection hole.

[0005] However, the deficiencies of the above-mentioned directional lighting lamps are as follows:

[0006] First, if the rear cover and the lamp body are fixedly connected through a buckle structure, it is required to achieve a tight fit between the buckle and the card slot. Therefore, high forming accuracy is required for the buckle and the card slot, and high material properties are also required for the rear cover, so the production cost will also increase, and there is also a risk that the buckle and the card slot will become disengaged during the fall or transportation of the directional lighting lamp.

[0007] Second, if the rear cover and the lamp body are fixedly connected through self-tapping screws, when the self-tapping screw processes self-tapping threads for the connection hole, internal stress will be generated in the surrounding structure (plastic material) of the connection hole, and there is a risk of cracking. Moreover, since the self-tapping screw is only threadedly connected to the connection hole, when the surrounding structure of the connection hole cracks to a certain extent, the rear cover will fall off.

[0008] Thirdly, the optoelectronic component is fixed in the lamp cavity by self-tapping screws. It processes self-tapping threads on the connection holes at the bottom of the lamp cavity through the self-tapping screws to achieve threaded connection with the connection holes. However, since the lamp body is made of aluminum, there is a risk of slipping teeth when the self-tapping screws process self-tapping threads on the connection holes, which may lead to the detachment of the optoelectronic component. Moreover, when the rear cover and the lamp body are also connected by self-tapping screws, the overall assembly of the directional lighting fixture requires a relatively large number of self-tapping screw installations, which is not conducive to improving the assembly efficiency. Summary of the Invention

[0009] To solve the above problems, the main object of the present utility model is to provide a directional lighting fixture that is easy to assemble and can reduce the risk of detachment of the rear cover and the optoelectronic component.

[0010] Another object of the present utility model is to provide a lighting system provided with the above-mentioned directional lighting fixture.

[0011] To achieve the main object of the present utility model, the present utility model provides a directional lighting fixture, including a lamp body, a rear cover and an optoelectronic component. The lamp body has a lamp cavity, and the opening of the lamp cavity is formed at the front end of the lamp body. The rear cover is installed at the rear end of the lamp body, and the optoelectronic component is located in the lamp cavity and installed on the bottom wall of the lamp cavity. The optoelectronic component is provided with a first through hole. Among them, the bottom wall is provided with a through slot and a first connection hole, and the rear cover is provided with a first buckle and a second connection hole. The first buckle is snap-fitted with the slot, and the directional lighting fixture further includes a self-tapping screw. The self-tapping screw passes through the first through hole and is threadedly connected to the first connection hole and the second connection hole respectively.

[0012] Secondly, as can be seen from the above, by processing self-tapping threads on the first connection hole and the second connection hole through the self-tapping screws and then threadedly connecting with the first connection hole and the second connection hole, a double-layer protection can be provided for the fixation of the optoelectronic component. When the first connection hole has slipping teeth or the peripheral structure of the second connection hole cracks, the optoelectronic component can still be reliably fixed on the lamp body. Moreover, by making the rear cover and the lamp body be snap-fitted, it can not only position the rear cover and the lamp body when the self-tapping screw is threadedly connected to the second connection hole, making the installation of the self-tapping screw more convenient, but also enable the rear cover and the lamp body to have a composite connection structure, improving the reliability of the connection between the rear cover and the lamp body. And since the purpose of the snap-fit connection between the first buckle and the slot is to preliminarily fix the rear cover to the lamp body, there is no need for a tight fit between the first buckle and the slot, reducing the requirements for the rear cover material and the production cost.

[0013] A preferred solution is that the rear cover is provided with a chip removal port at the orifice of the second connection hole, and the chip removal port penetrates the hole wall of the second connection hole.

[0014] As can be seen from the above, when the self-tapping screw taps the first connection hole, the debris cut from the lamp body can be discharged from the chip removal port to prevent the debris from being locked into the second connection hole and causing the surrounding structure of the second connection hole to crack.

[0015] Another preferred solution is that the bottom wall is provided with a positioning protrusion that extends toward the open end of the lamp cavity, and the optoelectronic component is also provided with a positioning through hole, and the positioning protrusion is inserted into the positioning through hole.

[0016] As can be seen from the above, this design enables the optoelectronic component to be positioned and limited when assembled with the lamp body, making the assembly of the optoelectronic component and the lamp body more convenient and easy to operate.

[0017] A further solution is that the optoelectronic component is also provided with an avoidance groove that penetrates itself, and the first buckle is inserted into the avoidance groove.

[0018] As can be seen from the above, the avoidance groove can avoid the first buckle, enabling the substrate of the optoelectronic component to be made as large as possible for the design and production of the optoelectronic component; at the same time, the avoidance groove can cooperate with the first buckle to assist the positioning protrusion and the positioning through hole to position and limit the optoelectronic component when the optoelectronic component is assembled with the lamp body, improving the reliability of positioning and limiting the optoelectronic component; furthermore, the avoidance groove, in cooperation with the first buckle, the positioning protrusion and the positioning through hole, can also play an anti-misassembly role when the optoelectronic component is assembled with the lamp body.

[0019] A further solution is that the number of the first buckles is between 2 and 4, the number of the card slots is between 2 and 4, and one card slot is arranged in cooperation with one first buckle; the optoelectronic component is also provided with a wiring groove that penetrates itself, and the bottom wall is provided with a grounding end at the wiring groove; the wiring groove and one of all the first buckles are combined and set as a whole.

[0020] As can be seen from the above, the design of the number of the first buckles and the card slots can ensure the assembly reliability of the rear cover and the lamp body, while making the structures of the rear cover, the lamp body and the optoelectronic component reasonable and avoiding too high production costs; the wiring groove can be used for the ground wire of the power supply cable to run, to ensure the use safety of the directional lighting fixture; and combining the wiring groove and one first buckle as a whole can simplify the substrate structure of the optoelectronic component.

[0021] A further solution is that the directional lighting fixture further includes a lens fixing member, the lens fixing member is placed in the lamp cavity, the lens fixing member is provided with a second through hole, the self-tapping screw first passes through the second through hole and then through the first through hole, and the optoelectronic component is clamped between the bottom wall and the lens fixing member;

[0022] The lens fixing member has a receiving cavity. The opening of the receiving cavity faces the optoelectronic component. The bottom of the receiving cavity is provided with a lens mounting opening that penetrates through the lens fixing member. A relief opening is formed by the inner concave of the side wall of the lens fixing member into the receiving cavity. The relief opening penetrates through the lens fixing member in the depth direction of the lamp cavity. A partition is provided in the relief opening, and a second through hole is formed in the partition and penetrates through the partition.

[0023] As can be seen above,

[0024] The lens fixing member is used to fix the lens, making the lens installation simpler and more efficient. When installing the lens, there is no need to clamp and fix it through the optoelectronic component and the anti-glare ring, effectively eliminating the cumulative tolerance between the optoelectronic component, the lens, and the anti-glare ring, and avoiding the situation of lens loosening or unable to be installed caused by the cumulative tolerance. In addition, when the lens fixing member is assembled in place, the optoelectronic component is naturally clamped and fixed between the lamp body and the lens fixing member, enabling the assembly of the lamp body, the rear cover, the optoelectronic component, and the lens fixing member to be completed only by a set of self-tapping bolts (i.e., there is no need for additional self-tapping screw connection between the optoelectronic component and the lamp body), effectively improving the assembly efficiency. Moreover, through the design of the lens fixing member, the strength of the lens fixing member is ensured, and the structure of the lens fixing member is simplified. By forming a relief opening and a partition on the lens fixing member, the space required for the assembly of the lens fixing member can be reasonably reduced, which is beneficial to the miniaturization design of the lamp body and the directional lighting fixture and reduces the production cost.

[0025] A further solution is that the number of the first through holes, the second through holes, the first connection holes, the second connection holes, and the relief openings is two each, and the number of partitions is two.

[0026] As can be seen above, this design can ensure the firmness of the assembly of the lamp body, the rear cover, the optoelectronic component, and the lens fixing member, making the assembly simpler and easier to operate, which is beneficial to improving the assembly efficiency and reducing the production cost.

[0027] A further solution is that the directional lighting fixture further includes a lens and an anti-glare ring. The lens is installed on the lens fixing member, a part of the lens is inserted into the lens mounting opening or the lens covers the lens mounting opening, and the anti-glare ring is installed on the lamp body and is located at the opening of the lamp cavity.

[0028] As can be seen above, installing the lens on the lens fixing member eliminates the need to set positioning feet on the lens and positioning holes on the optoelectronic component, simplifies the structures of the lens and the optoelectronic component, and at the same time makes the lens installation simpler and more efficient. There is no need to clamp and fix it through the optoelectronic component and the anti-glare ring, eliminating the cumulative tolerance between the optoelectronic component, the lens, and the anti-glare ring, thus avoiding the loosening of the lens or the inability to install the lens after installation caused by the cumulative tolerance.

[0029] A further solution is that the lens fixing member is provided with a limiting rib and a second buckle at the lens mounting opening. A clamping position is formed between the limiting rib and the second buckle. The lens is provided with an annular protrusion along its circumferential direction, and the annular protrusion is engaged in the clamping position.

[0030] As can be seen from the above, the lens fixing member can be quickly assembled with the annular protrusion on the lens through the limiting rib and the second buckle thereon, which is beneficial to improving the assembly efficiency. Moreover, through the cooperation among the limiting rib, the second buckle and the annular protrusion, it is possible to prevent the lens from loosening after assembly and ensure the assembly position of the lens.

[0031] To achieve another object of the present invention, the present invention provides a lighting system, including a control terminal. Among them, the lighting system further includes the above-mentioned directional lighting fixture, and the directional lighting fixture further includes a control unit, and the control unit is electrically connected to the optoelectronic component; the control terminal is electrically connected to the control unit, and / or the control terminal and the control unit perform information interaction.

[0041] Embodiment of the Directional Lighting Fixture

[0042] Reference Figure 1 Referring to Figure 1 , the directional lighting fixture 100 includes a lamp body 1, a rear cover 2, an optoelectronic component 3, a lens fixing member 4, a lens 5, a self-tapping screw 6, and an anti-glare ring 7.

[0043] Combined Figure 2 Combined with Figure 2 , the lamp body 1 has a lamp cavity 10, and the opening of the lamp cavity 10 is formed at the front end of the lamp body 1; the bottom wall 11 of the lamp cavity 10 is provided with a card slot 111 and a first connection hole 112, and both the card slot 111 and the first connection hole 112 penetrate the bottom wall 11 in the depth direction of the lamp cavity 10. Among them, the number of the card slots 111 is preferably between 2 and 4; preferably, as in this embodiment, the number of the card slots 111 is 3, and the 3 card slots 111 are evenly distributed along the circumferential direction of the lamp cavity 10. The number of the first connection holes 112 is preferably two, and the two first connection holes 112 are distributed along the circumferential direction of the lamp cavity 10.

[0044] Combined Figure 3 and Figure 4 Combined with Figure 3 and Figure 4 , the rear cover 2 is installed at the rear end of the lamp body 1, and the rear cover 2 is provided with a first buckle 21 and a second connection hole 22. Among them, the number of the first buckles 21 is preferably between 2 and 4, and the number of the first buckles 21 is equal to the number of the card slots 111, so that a first buckle 21 is arranged in cooperation with a card slot 111, and further the first buckle 21 can be snap-connected with a matching card slot 111. By designing the number of the first buckles 21 and the card slots 111, while ensuring the assembly reliability of the rear cover 2 and the lamp body 1, the structures of the rear cover 2, the lamp body 1, and the optoelectronic component 3 are reasonable, and the production cost is avoided from being too high. The number of the second connection holes 22 is equal to the number of the first connection holes 112, and a second connection hole 22 is arranged in cooperation with a first connection hole 112, so that a second connection hole 22 and a matching first connection hole 112 are coaxially arranged.

[0045] Combined Figure 5 and Figure 6 Combined with Figure 5 and Figure 6 , the optoelectronic component 3 is located in the lamp cavity 10, and the optoelectronic component 3 is on the bottom wall 11 of the lamp cavity 10. Among them, the optoelectronic component 3 is provided with a first through hole 31, the number of the first through holes 31 is equal to the number of the first connection holes 112, and a first through hole 31 is arranged in cooperation with a first connection hole 112. In the depth direction of the lamp cavity 10, the projection of the first through hole 31 is located within the projection of the first connection hole 112; preferably, the first through hole 31 and a matching first connection hole 112 are coaxially arranged.

[0046] Preferably, the optoelectronic component 3 is further provided with a positioning through hole 32, the positioning through hole 32 penetrates the optoelectronic component 3 in the depth direction of the lamp cavity 10, and the number of the positioning through holes 32 is preferably two; correspondingly, as Figure 2As shown, the bottom wall 11 of the lamp cavity 10 is provided with a positioning protrusion 113. The positioning protrusion 113 extends towards the opening of the lamp cavity 10. The positioning protrusion 113 is arranged in cooperation with the positioning through hole 32, and the number of the positioning protrusions 113 is equal to the number of the positioning through holes 32. When the optoelectronic component 3 is assembled with the lamp body 1, the positioning protrusion 113 is inserted into a corresponding positioning through hole 32. This design enables the optoelectronic component 3 to be positioned and limited when assembled with the lamp body 1, making the assembly of the optoelectronic component 3 and the lamp body 1 more convenient and easy to operate.

[0047] Furthermore, the optoelectronic component 3 is also provided with an avoidance groove 33. The avoidance groove 33 penetrates the optoelectronic component 3 in the depth direction of the lamp cavity 10. The number of the avoidance grooves 33 is equal to the number of the first buckles 21, so that one avoidance groove 33 is arranged in cooperation with one first buckle 21. When the optoelectronic component 3 is assembled onto the lamp body 1, the first buckle 21 is inserted into a corresponding avoidance groove 33. The avoidance groove 33 is used for the rear cover 2 to avoid the first buckle 21, so that the substrate of the optoelectronic component 3 can be made as large as possible, which is convenient for the design and production of the optoelectronic component 3. Moreover, the cooperation between the avoidance groove 33 and the first buckle 21 can also assist the positioning protrusion 113 and the positioning through hole 32 to position and limit the optoelectronic component 3 when the first buckle 21 assembles the optoelectronic component 3 and the lamp body 1, so as to improve the reliability of positioning and limiting the optoelectronic component 3. In addition, the avoidance groove 33 can also cooperate with the first buckle 21, the positioning protrusion 113 and the positioning through hole 32 to play an anti-misassembly role when the optoelectronic component 3 and the lamp body 1 are assembled, so as to prevent the optoelectronic component 3 from being misassembled. Preferably, the optoelectronic component 3 is also provided with a wiring groove 34. The wiring groove 34 penetrates the optoelectronic component 3 in the depth direction of the lamp cavity 10. Correspondingly, the bottom wall 11 of the lamp cavity 10 is provided with a grounding end 114 at the position of the wiring groove 34. The wiring groove 34 can be used for the ground wire of the power supply cable to run, so as to ensure the use safety of the directional lighting fixture 100. Among them, the grounding end 114 is preferably a connecting hole, so that the ground wire can be fixedly connected to the connecting hole through the wire ear and screw arranged at its own end. More preferably, the wiring groove 34 is integrated with one of all the first buckles 21 to simplify the substrate structure of the optoelectronic component 3.

[0048] Combined Figure 7 and Figure 8 , the lens fixing member 4 is placed in the lamp cavity 10. Among them, the lens fixing member 4 is provided with a second through hole 412, so that the self-tapping screw 6 can pass through the second through hole 412 and the first through hole 31 and then be threadedly connected to the first connecting hole 112 and the second connecting hole 22 respectively to clamp the optoelectronic component 3 between the bottom wall 11 and the lens fixing member 4.

[0049] Preferably, the lens fixing member 4 has a receiving cavity 40, the opening of the receiving cavity 40 faces the optoelectronic component 3, a relief opening 41 is formed by the side wall of the lens fixing member 4 concave inwardly into the receiving cavity 40, the relief opening 41 penetrates the lens fixing member 4 in the depth direction of the lamp cavity 10, a partition 411 is provided in the relief opening 41, and a second through hole 412 is formed in the partition 411 and penetrates the partition 411. This design can reasonably reduce the space required for the assembly of the lens fixing member 4, is conducive to the miniaturization design of the lamp body 1 and the directional lighting fixture 100, and reduces the production cost (because accessories such as the lamp body 11 and the anti-glare ring 75 can be made smaller, thus saving more production materials). Among them, the number of the second through holes 412 is equal to the number of the first connection holes 112, and a second through hole 412 is arranged in cooperation with a first connection hole 112. In the depth direction of the lamp cavity 10, the projection of the second through hole 412 is located within the projection of the first connection hole 112; preferably, the second through hole 412 and a first connection hole 112 arranged in cooperation are coaxially arranged; correspondingly, the number of the relief openings 41 and the number of the partitions 411 are both equal to the number of the second connection holes 22 and are all arranged in a matching manner, that is, in this embodiment, the number of the first through holes 31, the second through holes 412, the first connection holes 112, the second connection holes 22, and the relief openings 41 are all two, and the number of the partitions 411 is two; this design can ensure the firmness of the assembly of the lamp body 1, the rear cover 2, the optoelectronic component 3, and the lens fixing member 4, make the assembly simpler and easier to operate, is conducive to improving the assembly efficiency, and reduces the production cost.

[0050] In addition, as Figure 3 shown, the rear cover 2 is preferably provided with a chip removal opening 221 at the orifice of the second connection hole 22, and the chip removal opening 221 penetrates the hole wall of the second connection hole 22. The provision of the chip removal opening 221 enables the chips cut from the lamp body 1 to be discharged from the chip removal opening 221 when the self-tapping screw 6 taps the thread of the first connection hole 112, so as to prevent the chips from being locked into the second connection hole 22 and causing the surrounding structure of the second connection hole 22 to be cracked. At the same time, when the self-tapping screw 6 taps the thread of the second connection hole 22 of the chassis, the chips cut from the surrounding structure of the second connection hole 22 can also be discharged from the second connection hole 22 to a certain extent through the chip removal opening 221, thereby reducing the risk of the surrounding structure of the second connection hole 22 being cracked.

[0051] The lens fixing member 4 is provided with a lens mounting opening 42 which is formed at the bottom of the accommodation cavity 40 and penetrates the lens fixing member 4 in the depth direction of the lamp cavity 10. The lens 5 is mounted on the lens fixing member 4, and a part of the lens 5 is inserted into the lens mounting opening 42 or the lens 5 covers the lens mounting opening 42. Since the lens 5 is mounted on the lamp body 1 through the lens fixing member 4, there is no need to provide positioning feet on the lens 5 or positioning holes on the optoelectronic component 3, effectively simplifying the structures of the lens 5 and the optoelectronic component 3, and making the installation of the lens 5 simpler and more efficient at the same time; in addition, the lens 5 is no longer clamped and fixed by the cooperation of the optoelectronic component 3 and the anti-glare ring 7, so the cumulative tolerance between the optoelectronic component 3, the lens 5 and the anti-glare ring 7 is eliminated, avoiding the loosening of the lens 5 after installation or the inability to install the lens 5 due to the cumulative tolerance.

[0052] In this embodiment, for example, a part of the lens 5 is inserted into the lens mounting opening 42. Preferably, the lens fixing member 4 is provided with a limiting rib 421 and a second buckle 422 at the lens mounting opening 42, and a clamping position is formed between the limiting rib 421 and the second buckle 422; the lens 5 is provided with an annular protrusion 51 along its circumferential direction, and the annular protrusion 51 is preferably located at the large-diameter end of the lens 5, and the annular protrusion 51 is engaged in the clamping position; this design enables the lens fixing member 4 and the lens 5 to be quickly assembled, which is beneficial to improving the assembly efficiency, and the cooperation between the limiting rib 421, the second buckle 422 and the annular protrusion 51 can prevent the lens 5 from loosening after assembly and ensure the assembly position of the lens 5.

[0053] The anti-glare ring 7 is mounted on the lamp body 1 and is located at the open end of the lamp cavity 10. Preferably, the whole anti-glare ring 7 is located inside the lamp cavity 10; of course, as an alternative solution, a part of the anti-glare ring 7 can also be located outside the lamp cavity 10. In this embodiment, in order to facilitate the quick assembly between the anti-glare ring 7 and the lamp body 1 and make the assembly more convenient and easy to operate, the anti-glare ring 7 and the lamp body 1 are fixed through a buckle structure.

[0054] When the directional lighting fixture 100 is assembled, the rear cover 2 can be first assembled to the rear end of the lamp body 1 so that the first buckle 21 of the rear cover 2 is engaged with the card slot 111 on the lamp body 1, and the lens 5 is mounted on the lens fixing member 4 so that the lens 5 is located in the lens mounting opening 42 and the accommodation cavity 40.

[0055] Then, the optoelectronic component 3 is placed at the bottom of the lamp cavity 10 so that the positioning protrusion 113 on the bottom wall 11 is inserted into the positioning through hole 32 of the optoelectronic element, and the first buckle 21 of the rear cover 2 is inserted into the avoidance groove 33, so that the second connection hole 22 on the rear cover 2 is aligned with the first connection hole 112 on the lamp body 1 and the first through hole 31 on the optoelectronic component 3 which are arranged in cooperation.

[0056] Next, place the lens fixing member 4 with the lens 5 installed into the lamp cavity 10, make the lens fixing member 4 fit on the optoelectronic component 3, and align the second through hole 412 on the lens fixing member 4 with the first through hole 31 accurately.

[0057] Next, pass the self-tapping screw 6 through the second through hole 412 and the first through hole 31 and thread it with the first connection hole 112 and the second connection hole 22 respectively, so as to fix the lens 5 fixing seat on the lamp body 1, clamp the optoelectronic component 3 between the lamp body 1 and the lens fixing member 4, and further fix the rear cover 2 with the self-tapping screw 6.

[0058] Finally, install the anti-glare ring 7 onto the lamp body 1.

[0059] In summary, since the lens 5 is first assembled with the lens fixing member 4 into a whole and then assembled into the lamp cavity 10, the installation of the lens 5 is simpler and more efficient. And when installing the lens 5, there is no need to clamp and fix it through the optoelectronic component 3 and the anti-glare ring 7, effectively eliminating the cumulative tolerance between the optoelectronic component 3, the lens 5 and the anti-glare ring 7, and avoiding the situation that the lens 5 becomes loose or cannot be installed due to the cumulative tolerance.

[0060] In addition, by self-tapping the first connection hole 112 and the second connection hole 22 with the self-tapping screw 6 and then threading it with the first connection hole 112 and the second connection hole 22, it can provide double protection for the fixation of the lens fixing member 4, so that when the first connection hole 112 slips or the peripheral structure of the second connection hole 22 cracks, the lens fixing member 4 can still be reliably installed on the lamp body 1.

[0061] Furthermore, making the rear cover 2 and the lamp body 1 engage with each other can not only position the rear cover 2 and the lamp body 1 when the self-tapping screw 6 is threaded with the second connection hole 22 to make the installation of the self-tapping screw 6 more convenient, but also make the rear cover 2 and the lamp body 1 have a composite connection structure, improving the reliability of the connection between the rear cover 2 and the lamp body 1, reducing the risk of the rear cover 2 and the optoelectronic component 3 falling off. And since the purpose of the first buckle 21 engaging with the card slot 111 is to preliminarily fix the rear cover 2 to the lamp body 1, there is no need for a tight fit between the first buckle 21 and the card slot 111, reducing the requirements for the material of the rear cover 2 and the production cost.

[0062] In addition, when the lens fixing member 4 is assembled in place, the optoelectronic component 3 is naturally clamped and fixed between the lamp body 1 and the lens fixing member 4, so that the assembly of the lamp body 1, the rear cover 2, the optoelectronic component 3 and the lens fixing member 4 can be completed only by fixing with a set of self-tapping bolts (that is, there is no need for additional self-tapping screw connection between the optoelectronic component 3 and the lamp body 1), effectively improving the assembly efficiency.

[0063] Embodiment of the lighting system
