Description

[0002] A light guide is a device used for optical transmission, commonly found in optical devices and fiber optic communication systems. Its main function is to transmit light from one location to another and provide efficient beam control and light transmission. Light guides are widely used in many fields. In the field of LED lighting, circular light guides are widely used in downlights, spotlights, panel lights and other products. They can refract and reflect the light emitted by LEDs, so that the light is more evenly directed to the target area, improving the lighting effect and comfort.

[0003] When a light guide column is combined with a high-power LED light source, the LED light source will be in working state for a long time, which will cause the temperature of the light guide column to be high. As a result, the light guide column cannot be made of common optical materials such as PC (polycarbonate) and PMMA (polymethyl methacrylate), and can only be made of high-temperature resistant optical materials such as glass. At the same time, the temperature of the light guide column is too high for a long time, which will lead to poor stability of the product. Therefore, an efficient heat dissipation device for the light guide column is proposed. Utility Model Content
