AI Technical Summary

Technical Problem

The uneven distribution of light intensity in LEDs makes it difficult to achieve good lighting effects in different lighting scenarios. Excessive concentration can cause glare, while excessively wide-angle light can affect the brightness of the light.

Method used

Design an embedded light with a specific light emission angle. By combining a base plate, side plate, diffuser plate, and prism plate, the light emission angle can be controlled at around 90° through the refraction and reflection of the lens, diffuser plate, and prism plate. The anti-glare function is achieved through the structural design of the lens and prism plate.

Benefits of technology

It achieves uniform light distribution and good lighting effect, while effectively preventing glare, thus achieving excellent lighting effect and protection level.
