Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a light source component for a tri-proof lamp. Background Technology

[0002] Rugged lights are widely used in industrial lighting, outdoor lighting, and special environments (such as warehouses, workshops, and tunnels). Traditional rugged lights typically use LED strips mounted on a mounting plate as a single module, resulting in a simple structure. However, these traditional light sources often lack lenses, limiting their application to basic lighting needs. They cannot adjust optical performance for different environments, limiting their applicability. Furthermore, adjusting the optical effect or replacing damaged optical components often requires replacing the entire light source assembly, increasing operating costs. To address these issues, some rugged lights now incorporate lens plates on the LED strips. However, in conventional designs, the lens plate mounting structure is complex, making disassembly and assembly inconvenient. This hinders the maintenance and replacement of the LED strip, and also presents operational difficulties when replacing the lens plate for different usage scenarios. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a light source component for a tri-proof lamp that is simple in structure and easy to disassemble and assemble.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A light source assembly for a tri-proof lamp includes a mounting plate, a light strip, and a lens plate. The light strip is mounted on the mounting plate, and the lens plate covers the light strip and is detachably mounted on the mounting plate. The mounting plate is provided with a first limiting member along a first linear direction from left to right and a plurality of second limiting members along a second linear direction. The first linear direction and the second linear direction are parallel, so that the area on the mounting plate located between the first linear direction and the second linear direction constitutes a lens plate mounting area for mounting the lens plate. The first limiting member includes a first limiting wall vertically disposed on the mounting plate, the lower end of the first limiting wall being bent horizontally backward to form a first horizontal limiting part, and a first insertion groove being formed between the first limiting wall and the first horizontal limiting part. The second limiting member includes a second limiting wall vertically disposed on the mounting plate, the lower end of the second limiting wall being bent forward horizontally to form a second horizontal limiting part, and a second insertion groove being formed between the second limiting wall and the second horizontal limiting part. The lens plate includes a covering body portion that covers the light strip. The front end of the covering body portion is provided with a front insert portion that can be inserted into the first insertion slot, and the rear end of the covering body portion is provided with a rear insert portion that can be inserted into the second insertion slot. The mounting plate has a limiting protrusion at its first end in the left-right direction for limiting the corresponding first end of the lens plate. Correspondingly, the mounting plate has a limiting mounting member at its second end in the left-right direction opposite to the first end for limiting the corresponding second end of the lens plate.

[0005] The main body of the cover is recessed downwards to form a cover cavity, and the light strip is disposed within the cover cavity.

[0006] The cavity of the cover has an upwardly protruding positioning protrusion that abuts against the lower end face of the light strip. The light strip is press-fitted to the positioning protrusion by the mounting plate.

[0007] The light strip is provided with multiple LED beads, which constitute the main light-emitting area. A lens body is provided on the cover body corresponding to the main light-emitting area. A transmission cavity is recessed on the lens body, and the main light-emitting area is located in the transmission cavity.

[0008] The limiting mounting component is a mounting screw. The mounting plate has a mounting hole at the corresponding position. The shank of the mounting screw passes through the mounting hole and is screwed onto the lamp housing of the tri-proof lamp. The head of the mounting screw limits the second end of the lens plate.

[0009] Compared with the prior art, the advantages of this utility model are: simple structure and convenient assembly and disassembly. During assembly, the lens plate is inserted from the second end of the mounting plate toward the first end of the mounting plate, so that the front insertion part is inserted into the corresponding first insertion slot and the rear insertion part is inserted into the corresponding second insertion slot. The first and second limiting parts form a limit on the lens plate in the vertical and horizontal directions. After the insertion is in place, the first end of the lens plate is limited by the limiting protrusion. Then, the upper limit mounting part is assembled. The limiting protrusion and the upper limit mounting part form a limit on the lens plate in the left and right directions. During disassembly, only the upper limit mounting part needs to be removed to pull it out from the lens plate, which facilitates the replacement of the lens plate as needed and the maintenance, inspection and replacement of the light strip.

Detailed Implementation

[0011] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0012] As shown in the figure, a light source assembly for a tri-proof lamp includes a mounting plate 1, a light strip 2, and a lens plate 3. The light strip 2 is mounted on the mounting plate 1, and the lens plate 3 covers the light strip 2 and is detachably mounted on the mounting plate 1. The mounting plate 1 is provided with a first limiting member 4 along a first linear direction from left to right and a plurality of second limiting members 5 along a second linear direction. The first linear direction and the second linear direction are parallel, so that the area on the mounting plate 1 located between the first linear direction and the second linear direction constitutes the lens plate mounting area for mounting the lens plate 3. The first limiting member 4 includes a first limiting wall 41 vertically disposed on the mounting plate 1. The lower end of the first limiting wall 41 is bent backward horizontally to form a first horizontal limiting part 42. A first insertion groove 43 is formed between the first limiting wall 41 and the first horizontal limiting part 42. The second limiting member 5 includes a second limiting wall 51 vertically disposed on the mounting plate 1. The lower end of the second limiting wall 51 is bent forward horizontally to form a second horizontal limiting part 52. A second insertion groove 53 is formed between the second limiting wall 51 and the second horizontal limiting part 52. The lens plate 3 includes a covering body 31 that covers the light strip 2. The front end of the covering body 31 is provided with a front insertion part 32 that can be inserted into the first insertion slot 43, and the rear end of the covering body 31 is provided with a rear insertion part 33 that can be inserted into the second insertion slot 53. The mounting plate 1 has a first end protruding in the left-right direction, which is provided with a limiting protrusion 11 for limiting the corresponding first end of the lens plate 3. Correspondingly, the mounting plate 1 has a second end opposite to the first end in the left-right direction, which is provided with a limiting mounting member 12 for limiting the corresponding second end of the lens plate 3.

[0013] In this specific embodiment, a covering cavity 311 is provided in a downward recess on the upper part of the covering body 31, and the lamp strip 2 is disposed in the covering cavity 311. The downward recessed covering cavity 311 provided on the covering body 31 can tightly accommodate the lamp strip 2, provide a stable installation space, enhance the compactness of the overall structure, and make the protection performance of the light source assembly better.

[0014] In this specific embodiment, a positioning protrusion 312 is provided protruding upward within the cavity 311. The positioning protrusion 312 abuts against the lower end face of the light strip 2, and the light strip 2 is press-fitted and fixed to the positioning protrusion 312 by the mounting plate 1. The upward-protruding positioning protrusion 312 within the cavity 311 cooperates with the mounting plate 1 to form a bidirectional pressing and fixing of the light strip 2, ensuring that the light strip 2 is stably installed, avoiding poor contact or detachment due to vibration or external impact, and improving the reliability of the lamp.

[0015] In this specific embodiment, the light strip 2 is provided with multiple LED beads 21, which constitute the main light-emitting area. A lens body 30 is provided on the covering body 31 corresponding to the main light-emitting area. A transmission cavity 301 is recessed in the lens body 30, and the main light-emitting area is located within the transmission cavity 301. By providing the lens body 30 on the covering body 31 corresponding to the main LED light-emitting area and precisely covering the LED beads 21 through the transmission cavity 301, the light distribution is optimized, light loss is reduced, and the uniformity and efficiency of illumination are improved.

[0016] In this specific embodiment, the limiting mounting component 12 is a mounting screw. A mounting hole (not shown in the figure) is provided at the corresponding position on the mounting plate 1. The shank of the mounting screw passes through the mounting hole and is screwed onto the lamp housing of the tri-proof lamp. The head of the mounting screw limits the second end of the lens plate 3. By fixing the mounting screw to the lamp housing, the mounting plate 1 is fixedly installed inside the lamp body. Simultaneously, the screw head reliably limits the end of the lens plate 3, ensuring that the lens plate 3 is stable and does not shift in the left-right direction.
