[0022] The lens module 4 includes an optical lens 41 fixed to the bracket 1 and a quartz lens 42 disposed above the optical lens 41. The lower end face of the optical lens 41 is placed above the high-power LED chip 2, and a first gap 101 is formed therebetween; a groove 421 is formed at the lower end of the quartz lens 42, and the groove 421 is placed above the upper end face of the optical lens 41, and a second gap 102 is formed therebetween; at least one of the upper and lower end faces of the optical lens 41 is provided with a first optical pattern 411 for improving the light uniformity. The quartz lens 42 and the optical lens 41 of the present utility model are installed on the bracket 1 by upper and lower stacked assembly and placed above the high-power LED chip 2. A first gap 101 is formed between the optical lens 41 and the high-power LED chip 2, a second gap 102 is formed between the quartz lens 42 and the optical lens 41, and at least one of the upper and lower end faces of the optical lens 41 is provided with the first optical pattern 411 for improving the light uniformity. When the high-power LED chip 2 is lit to generate light, the light first passes through the optical lens 41, and after being homogenized by the first optical pattern 411 on the optical lens 41, it then shoots towards the quartz lens 42 and passes through the quartz lens 42 to irradiate the outside, thereby achieving the purpose of emitting light. Since the light is refracted twice by the optical lens 41 and the quartz lens 42, the light can be made uniform to a certain extent. Especially when the light passes through the first optical pattern 411 on the optical lens 41, the uniformity of the light becomes better, thereby effectively reducing the generation of dark spots / dark areas, ensuring the lighting effect as a visual light source, and having extremely strong market competitiveness.
[0023] Both the upper and lower end faces of the optical lens 41 are provided with the first optical pattern 411, so that the light can pass through the first optical pattern 411 twice, and thus the light can be homogenized twice, and further the light emitted by the present utility model can be made more uniform, and the lighting effect of the visual light source is better.

[0026] The bracket 1 is a ceramic bracket, which has an ideal heat dissipation effect.
[0027] A recess 11 is provided in the middle of the bracket 1, and the high-power LED chip 2 is placed in the recess 11. The height of the high-power LED chip 2 is less than the depth of the recess 11, so that the optical lens 41 can be made into a sheet shape without having to dig a groove to accommodate the high-power LED chip 2, making the structure of the optical lens 41 simpler and more convenient to process. Among them, the optical lens 41 can be a sapphire lens, which has a higher light transmittance and better light transmission effect.
[0028] Both the first conductive sheet 31 and the second conductive sheet 32 are in a semi-square frame structure, which are respectively clamped and fixed on both sides of the bracket 1. The lower ends of the first conductive sheet 31 and the second conductive sheet 32 are respectively bent to form parts that fit on both sides of the lower end of the bracket 1. The assembly structure of the first conductive sheet 31 and the second conductive sheet 32 with the bracket 1 is simple and the structure is stable.
[0029] The number of the conductive sheets is two, which are the first conductive sheet 31 and the second conductive sheet 32 respectively. The upper end of the first conductive sheet 31 is partially fitted and fixed on the bottom surface of the recess 11, and the upper end of the second conductive sheet 32 is partially fitted and fixed on the bottom surface of the recess 11, which can make the first conductive sheet 31 and the second conductive sheet 32 be assembled on both sides of the bracket 1 more stably.
[0030] The first electrode on the lower end surface of the high-power LED chip 2 is directly attached to the upper end surface of the second conductive sheet 32 and welded and fixed to form an electrical connection. The second electrode of the high-power LED chip 2 is connected to the first conductive sheet 31 through a gold wire.

[0033] In summary, the quartz lens 42 and the optical lens 41 of the present utility model are assembled in a stacked manner up and down and are installed on the bracket 1, and are placed above the high-power LED chip 2. A first gap 101 is formed between the optical lens 41 and the high-power LED chip 2, a second gap 102 is formed between the quartz lens 42 and the optical lens 41, and at least one of the upper and lower end faces of the optical lens 41 is provided with a first optical pattern 411 for improving the light uniformity. When the high-power LED chip 2 is lit to generate light, the light first passes through the optical lens 41, and after being homogenized by the first optical pattern 411 on the optical lens 41, it then shoots towards the quartz lens 42 and passes through the quartz lens 42 to irradiate the outside world, thereby achieving the purpose of emitting light. Since the light is refracted twice through the optical lens 41 and the quartz lens 42, the light can be made uniform to a certain extent. Especially when the light passes through the first optical pattern 411 on the optical lens 41, the uniformity of the light becomes better, thereby effectively reducing the generation of dark spots / dark areas, ensuring the lighting effect as a visual light source, and having extremely strong market competitiveness.
