It is a core support component in LED lighting or display equipment.

[0003] A search revealed a Chinese utility model patent, CN222210118U, which discloses an LED light source fixing bracket structure. The lens module is an anti-glare lens. Multiple positioning grooves are evenly distributed on the outer wall of the reflector. Each positioning groove contains a locking block. The anti-glare lens has multiple buckles that are fastened to the locking blocks. The width of the positioning groove is equal to the width of the buckle. After the buckle is inserted into the positioning groove, it is fastened to the locking block. The inner surface of the buckle is attached to the side surface of the positioning groove. Using this utility model, the connection force of the light source fixing bracket structure is more stable, and the anti-glare lens connected by the buckles is easy to replace. The inner surface of the buckle is attached to the side surface of the positioning groove, resulting in higher coaxiality between the anti-glare lens and the reflector.

[0004] However, the device lacks the function of controlling the lighting intensity. When in use, the reflector cup and the light source fixing bracket are fixedly connected, and the reflective intensity cannot be adjusted, thus the lighting intensity cannot be changed and cannot meet diverse needs.

A mounting plate 12 is fixedly connected to the bottom end of the damping springs 11, and a ring groove 13 is opened on the top of the mounting plate 12. The retaining strip 10 is slidably connected inside the ring groove 13. In use, pressing the fixing ring 1 compresses the damping springs 11, rotating the fixing ring 1 causes the retaining strip 10 to rotate 90 degrees inside the ring groove 13, and the retaining strip 10 disengages from the positioning groove 14 and slides to the insertion groove 15. Pressing is stopped, and the fixing ring 1 is... The retaining strip 10 is removed from the mounting plate 12.

[0026] In this embodiment, preferably, the inner wall of the annular groove 13 near the retaining strip 10 has a positioning groove 14, and the inner wall of the annular groove 13 away from the retaining strip 10 has an insertion groove 15. In use, pressing the fixing ring 1 compresses the damping spring 11, rotating the fixing ring 1 causes the retaining strip 10 to rotate 90 degrees inside the annular groove 13. The retaining strip 10 disengages from the positioning groove 14 and slides into the insertion groove 15.

In use, pressing the reflector 5 causes the arc plate 3 to slide downwards inside the ring groove 2, compressing the damping spring 4. The locking block 8 slides downwards inside the locking slot 7 until its bottom contacts the inner bottom wall of the ring groove 9. Then, the reflector is rotated 45 degrees, and pressing stops. Under the action of the damping spring 4, the reflector 5 moves the arc plate and the locking block 8 upwards, and the locking block 8 engages in the other locking slot 7. With the reflector fixed, reflector 5 rotates 45 degrees relative to reflector 6. By adjusting the reflector 6 to match the strong reflector 18 or weak reflector 17 of reflector 5 as needed, different intensities of reflection can be obtained. The locking block 8 and the locking slot 7 are both provided in two places, and the angle between the line connecting the two and the center point of the fixing ring 1 is 45 degrees, ensuring that the rotation angle between reflector 5 and reflector 6 can only be 45 degrees, thereby controlling the light intensity to have two variations. The operation is simple and meets more usage needs.

[0029] In this embodiment, preferably, reflector 1 5 is annular in top view, and reflector 2 6 is cross-shaped in top view. Reflector 1 5 is composed of four weak reflective sheets 17 and four strong reflective sheets 18 welded together adjacently, and reflector 2 6 is composed of four strong reflective sheets 18 spaced equally apart. In use, pressing reflector 1 5 causes the arc plate 1 3 to slide downward inside the annular groove 1 2, compressing the damping spring 1 4. The locking block 8 slides downward inside the locking groove 7 until its bottom contacts the inner bottom wall of the annular groove 2 9. Then, the reflector is rotated forty-five degrees, and pressing is stopped. Under the action of the damping spring 1 4, reflector 1 5 causes the arc plate and locking block 8 to move upward, and the locking block 8 is locked into another locking groove 7, fixing the two reflectors. At this time, reflector 1 5 is rotated forty-five degrees relative to reflector 2 6. The strength of reflector 2 6 and reflector 1 5 can be adjusted as needed. The reflector 18 or weak reflector 17 are used in conjunction; wherein, reflector 1 5 is composed of eight reflectors of the same size with their edges tightly welded together, four of which are strong reflectors 18 and four are weak reflectors 17, arranged at intervals. Reflector 2 6 is composed of four strong reflectors 18 of the same size with equal spacing. The four reflectors are welded to the circular plate at the bottom of reflector 2 6, and the circular plate is then fixedly connected to the fixing ring 1. The arrangement of the four reflectors is reflector, gap, and reflector. When the gap of reflector 2 6 is aligned with the strong reflector 18 of reflector 1 5, the overall reflective intensity of the device is high. When the gap of reflector 2 6 is aligned with the weak reflector 17 of reflector 1 5, the overall reflective intensity of the device is low. The intensity difference of the reflectors and their specific materials and principles are existing technologies and will not be explained in detail here.

[0030] Working Principle: In this embodiment, when using an LED light source fixing bracket device, pressing the reflector 5 causes the arc plate 3 to slide downwards inside the annular groove 2, compressing the damping spring 4. The locking block 8 slides downwards inside the slot 7 until its bottom contacts the inner bottom wall of the annular groove 9. Then, the reflector is rotated 45 degrees, and the pressing stops. Under the action of the damping spring 4, the reflector 5 moves the arc plate and the locking block 8 upwards, and the locking block 8 engages with another slot 7, fixing the two reflectors. At this time, the reflector 5 has rotated 45 degrees relative to the reflector 6. The reflector 6 and the reflector can be adjusted as needed. By combining the strong reflector 18 or the weak reflector 17 of the cover 5, different intensities of reflection can be obtained. Pressing the fixing ring 1 compresses the damping spring 11. Rotating the fixing ring 1 causes the locking strip 10 to rotate 90 degrees inside the ring groove 13. The locking strip 10 disengages from the positioning groove 14 and slides to the insertion groove 15. Stop pressing and remove the fixing ring 1 and the locking strip 10 from the mounting plate 12. During installation, align the locking strip 10 with the insertion groove 15, press and rotate 90 degrees to make the locking strip 10 snap into the positioning groove 14. The operation is simple and convenient for replacing different specifications of the mounting plate 12, thereby improving the adaptability of the device.
