Rectangular light spot lens module and preparation method thereof

Abstract

The invention relates to the technical field of semiconductor lighting. Particularly, the invention relates to a rectangular grating lens module and a preparation method thereof. The rectangular grating lens module comprises a heat dissipation module, the heat dissipation module comprises a heat dissipation module main body, a heat dissipation piece, an air gap, a heat dissipation sheet, heat conduction silicone grease, threaded holes, heat dissipation holes and limiting grooves; the heat dissipation sheet is fixedly clamped in the heat dissipation module main body; an air gap is reserved between the heat dissipation module body and the heat dissipation sheet, the heat dissipation holes are formed in the front end face and the rear end face of the heat dissipation module main body, the threaded holes are formed in the four corners of the side end face, deviating from the ventilation module, of the heat dissipation module main body, and the limiting grooves are formed in one side of theedges of the front end face and the rear end face of the heat dissipation module main body. According to the rectangular grating lens module, the heat dissipation effect of the rectangular grating lens module is greatly improved, and the service life of a product is prolonged.

Description

Technical field [0001] The invention relates to the technical field of semiconductor lighting, in particular to a rectangular spot lens module and a preparation method thereof. Background technique [0002] The LED lens is closely linked with the LED to enhance the light use efficiency and luminous efficiency. Different lenses can be used to change the light field distribution of the LED according to different effects. With the continuous growth of LED technology, the power of LEDs continues to increase, and at the same time, the illuminating spots of LEDs are also diversified. Among them, rectangular spot lens modules are mainly used in fields such as automobiles, street lights, and flashlights. At present, the rectangular spot lens module has high brightness and high LED module power. However, the product heat dissipation is poor, which in turn causes the temperature in the lens module to be too high, which affects the lens accuracy. At the same time, the service life of the LE...

AI Technical Summary

Problems solved by technology

At present, the rectangular spot lens module has high illumination brightness and high LED module power. However, the heat dissipation of the product is poor, which leads to high temperature in the lens module and affects the lens accuracy. At the same time, the service life of the LED lighting module is greatly reduced under high temperature. As a result, the rectangular spot lens module cannot work stably for a long time
