Light guide lighting is called Tubular Daylighting System abroad, and the domestic standard name is light guide daylighting system.
This is a non-electric lighting system, and buildings using this system can use sunlight for indoor lighting during the day. The basic principle is to efficiently collect outdoor natural light through a lighting cover and introduce it into the system for redistribution. After being transmitted through a specially made light pipe, the diffusion device at the bottom will illuminate the natural light evenly and efficiently to any place where light is needed. From dawn to dusk, or even on cloudy days, the light pipe daylighting system introduces enough light into the room. The device mainly consists of three parts: lighting device, light guide device, and diffusion device.
The core component of the system:
Light pipe. Mainly used to transmit light. Using the colorful unlimited light guide with international patented technology, the primary reflectance of light is 99.7%, which exceeds the physical limit of 98%, and can transmit sunlight most effectively.
Note: Compared with a light guide with a reflectivity of 99.7% and a light guide with a reflectivity of 98%, when the pipe is 1 meter long, the lighting efficiency differs by 13%. When the pipe is 3 meters long, the lighting efficiency differs by 13%. 1.51 times.
The lighting cap with patented technology can filter out 100% of ultraviolet rays. The non-metallic film of the colorful unlimited light pipe does not conduct infrared rays, and the entire system only transmits 100% of visible light. It is comfortable to use and can effectively prevent ultraviolet rays from damaging indoor items. At the same time, it will not transmit solar heat radiation into the room, reduce indoor air conditioning load, and truly achieve energy saving in buildings.
Diffuser: Adopts Fresnel lens technology to diffuse light evenly into the room, so that the room can be bathed in soft natural light no matter morning, evening or noon.
