[0002] COB (Chip On Board) light sources are integrated surface light source technologies that directly mount chips onto a substrate. They are widely used in the lighting field. However, in applications requiring long lifespan and high reliability, such as industrial lighting, plant lighting, stage lighting, and automotive lighting, close temperature monitoring is a key measure to ensure product lifespan.

Detailed Implementation

[0028] 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.

[0029] Reference Figures 1-2 This utility model provides an embodiment of an anti-interference COB light source thermocouple mounting bracket, comprising a light source body 3, which is a high-power COB light source. A base frame 1 is provided at the lower part of the light source body 3 for connecting various components. A heat dissipation mechanism is provided on the outside of the base frame 1, which is a heat dissipation mechanism of existing high-power light sources, such as a heat dissipation shell. A mounting bracket 2 is provided at the upper part of the light source body 3 for mounting and fixing the light source body 3. A thermocouple body 4 is provided at the lower part of the light source body 3 for temperature measurement, thereby realizing temperature detection when the light source is in use, and thus better coordinating heat dissipation adjustment. It is a patch thermocouple, which can be fixed by adhesive.

[0030] like Figures 3-5As shown, the base frame 1 has an auxiliary groove 16 at the top, which is used to provide installation space for the thermocouple. The thermocouple body 4 is installed in the auxiliary groove 16. The auxiliary groove 16 has a second wire-passing port 15 at the rear, which is used to connect and install the thermocouple wires. The wires of the thermocouple body 4 pass through the second wire-passing port 15. The base frame 1 has a first fixing port 13 in the middle, which is also used to install and fix the mounting bracket 2. The base frame 1 has a first wire-passing port 14 on both the left and right sides, which is used to install the light source circuit. The side wall of the base frame 1 has multiple heat dissipation vents 11, which are used to facilitate air circulation. The top of the inner wall of the base frame 1 is fixedly connected to multiple heat sinks 12, which are heat dissipation fins used to facilitate heat dissipation. The multiple heat sinks 12 are arranged radially.

[0031] Furthermore, wires 31 are installed on both the left and right sides of the light source body 3 for wiring connections with the light source body 3. The wires 31 pass through the first wire hole 14. The front, back, left, and right sides of the light source body 3 are provided with second fixing holes 32 for fixing the light source. The first fixing hole 13, the second fixing hole 32, and the third fixing hole 23 are all connected by bolts with threads for fixing the base frame 1, the light source body 3, and the mounting bracket 2.

[0032] Furthermore, the bottom of the mounting bracket 2 is provided with a mounting groove 21 for mounting the light source. The inner wall of the mounting groove 21 is provided with an anti-interference layer 24, which may be a graphene coating. The middle of the mounting bracket 2 is provided with three fixing ports 23, and there are multiple of them, for bolts to pass through. The left and right sides of the mounting bracket 2 are provided with mating grooves 22 for mounting the wires 31. On the side of the two mating grooves 22 that are close to each other, there is a rectangular groove 221 for mounting the wire terminals of the wires 31. The rectangular groove 221 and the mating groove 22 are connected by a connecting port 222. The wires 31 pass through the rectangular groove 221 and the connecting port 222 and are installed into the first wire through port 14.

[0033] Working principle: During installation, firstly, the thermocouple body 4 is attached to the back of the light source body 3. Then, the light source body 3 is inserted into the mounting groove 21 at the bottom of the mounting bracket 2. At the same time, the wires 31 on the left and right sides of the light source body 3 are passed through the rectangular grooves 221 on the mounting bracket 2 so that the wires 31 pass through the connection port 222 and enter the mating groove 22. Then, the mounting bracket 2 and the light source body 3 are installed on the base frame 1. During the installation process, the wires 31 on the light source body 3 are passed through the two No. 1 wire holes 14 respectively. At the same time, the thermocouple body 4 can be installed in the auxiliary groove 16, and the wiring terminal of the thermocouple is passed through the No. 2 wire hole 15. Then, the mounting bracket 2 and the base frame 1 are fully tightened, and the bolts are tightened to the No. 1 fixing port 13, the No. 2 fixing port 23 and the No. 3 fixing port 32, thereby fixing the base frame 1, the mounting bracket 2 and the light source body 3.

[0034] When the light source body 3 generates heat during use, the thermocouple body 4 will monitor the temperature to provide heat dissipation data to assist in the heat dissipation operation of the high-power COB light source. At the same time, the air that assists in heat dissipation will flow to the lower part of the base frame 1 through the heat dissipation port 11. When the gas passes between multiple heat sinks 12, heat exchange can be generated to complete the heat dissipation.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
