[0002] COB light sources are high-power light-emitting devices that integrate and package multiple LED chips directly onto the same substrate. Their core features are integration, surface emission, and high power density. They are widely used in lighting scenarios where high brightness and light spot uniformity are required, such as outdoor construction lights and street lights.

[0003] Common COB (Chip-on-Board) light sources integrate the COB light source with an aluminum alloy housing. However, these COB light sources lack focusing and enhancement devices, causing the light to diffuse rapidly over short distances. As outdoor construction lights, they cannot meet the needs of construction workers for clear identification of distant targets, and as streetlights, they result in insufficient illumination in the core areas of the road surface. Therefore, a COB light source focusing and enhancement device is proposed. Utility Model Content

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides a technical solution: such as Figure 1 As shown, in this embodiment, a COB light source focusing enhancement device includes a light source body 100, a focusing shell 200, a reflector cup 300, a focusing lens 400, a grid plate 500, and a protective cover 600. The focusing shell 200 is fixedly installed on the reflective end of the light source body 100. The reflector cup 300, the focusing lens 400, the grid plate 500, and the protective cover 600 are arranged sequentially from the inside to the outside inside the focusing shell 200. An adjustment component 700 is provided between the focusing lens 400 and the focusing shell 200.

[0017] The reflector cup 300 is located in the innermost layer, close to the light source. Its curved surface can reflect stray light rays that radiate to the sides and back of the light source back to the direction of the main optical axis, reducing light energy waste and improving light utilization. The focusing lens 400 refracts and calibrates the light output from the reflector cup, corrects the spot deviation, and makes the light focusing accuracy higher and the illumination of the target area more uniform. The grid plate 500 is located outside the focusing lens 400. It intercepts stray light rays that exceed the design beam angle in the light output from the lens through honeycomb-shaped small holes, preventing the light from spreading to non-target areas and reducing glare. The outermost protective cover 600 can block dust, rainwater, mud and other foreign objects in the outdoor construction environment from entering the outer shell and prevent contamination of the reflector cup, lens and grid surface.

[0018] The reflector cup 300 has a conical structure and is made of aerospace-grade aluminum alloy; the focusing lens 400 uses a TIR (total internal reflection) lens.

[0019] like Figure 3 As shown, the adjustment assembly 700 includes sliders 701, sleeves 702, and adjusting screws 703. Three sleeves 702 are fixedly installed on the outer wall of the focusing housing 200, arranged in a circular array. The interior of each sleeve 702 is in communication with the interior of the focusing housing 200. Three sliders 701 are fixedly installed on the outer wall of the focusing lens 400, arranged in a circular array. The three sliders 701 are respectively disposed within the three sleeves 702, and the sliders 701 slide against the inner wall of the sleeves 702. The interior of one sleeve 702 is configured with... An adjusting screw 703 is provided, with its two ends rotatably connected to the two inner walls of the sleeve 702. A slider 701 has a second threaded hole 704, which is fitted onto the outer surface of the adjusting screw 703. The second threaded hole 704 is threaded into the adjusting screw 703. One end of the adjusting screw 703 extends to the outside of the focusing housing 200. An adjusting component 705 is fixedly connected to the extended end of the adjusting screw 703. Several anti-slip slots 706 are provided on the outer wall of the adjusting component 705, and the anti-slip slots 706 are arranged in a ring array.

[0020] In use, rotating the adjusting component 705 drives the adjusting screw 703 to rotate, which in turn causes the slider 701 to slide inside the sleeve 702, thereby moving the focusing lens 400 within the focusing housing 200. This achieves the purpose of adjusting the distance between the focusing lens 400 and the light source body 100, making the light source more widely applicable. When the lens moves towards the light source, the beam angle will decrease, the light convergence will be stronger, and the illumination distance will be longer, making it suitable for high-altitude operations, remote equipment maintenance, and other scenarios. When the lens moves away from the light source, the beam angle will increase, and the illumination range will be wider, making it suitable for floodlighting needs such as large-area construction sites and temporary camps.

[0021] To prevent the focusing lens from becoming loose after adjustment (400°), the following settings should be made: Figure 4 As shown, a mounting base 800 is fixedly provided on the outer wall of the focusing housing 200, located on the side of the adjusting member 705. A locking bolt 801 is provided on the mounting base 800, and the locking bolt 801 passes through the mounting base 800 and is threadedly connected to the mounting base 800.

[0022] In use, after the position of the focusing lens 400 is adjusted, rotate the locking bolt 801 so that the end of the locking bolt 801 abuts against the side wall of the adjusting member 705, thereby locking the adjusting member 705 and preventing external vibration from causing the adjusting member 705 and the adjusting screw 703 to rotate, which would cause the position of the focusing lens 400 to shift.

[0023] like Figure 6 As shown, a mounting groove 201 is provided on the inner side of the opening end of the focusing housing 200. The grille plate 500 is disposed in the mounting groove 201. The grille plate 500 and the mounting groove 201 are adapted to each other. A first threaded hole 202 is provided on the inner wall of the opening of the mounting groove 201. The protective cover 600 is threadedly connected to the first threaded hole 202.

[0024] like Figure 8 As shown, the protective cover 600 consists of an edge sealing plate 601, an external threaded sleeve 602, and a transparent cover 603. The edge sealing plate 601 has an annular plate structure. One end of the edge sealing plate 601 is fixedly connected to the external threaded sleeve 602. The outer wall of the external threaded sleeve 602 is threadedly connected to the inner wall of the first threaded hole 202. The transparent cover 603 is fixedly installed on the inner wall of the edge sealing plate 601.

[0025] During installation, the external threaded sleeve 602 is rotated and inserted into the first threaded hole 202. The end of the external threaded sleeve 602 will abut against the end of the grid plate 500 to ensure that the grid plate 500 will not move axially. The edge sealing plate 601 will abut against the port of the focusing housing 200.

[0026] An observation port 203 is provided on the outer wall of the focusing housing 200. The observation port 203 extends into the interior of the focusing housing 200. A transparent plate 205 is fixedly provided on the inner wall of the observation port 203. An observation scale 204 is provided on the outer wall of the focusing housing 200 to the side of the observation port 203.

[0027] The distance the focusing lens 400 moves can be known in real time through the observation port 203 and the observation scale 204.

[0028] Two connecting plates 101 are fixedly installed on the outer wall of the light source body 100, and the two connecting plates 101 are symmetrically arranged on both sides of the outer wall of the light source body 100.

[0029] The device can be easily fixed to the mounting bracket by means of the connecting plate 101.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
