[0002] Explosion-proof places refer to places where there is a risk of explosion accidents due to the presence of explosive mixtures and preventive measures must be taken for their production, use, storage and loading and unloading. These places are divided into three levels according to their hazard levels: particularly dangerous places, highly dangerous places and generally dangerous places. In explosion-proof places, safety management is of vital importance to prevent casualties. For safety reasons, explosion-proof places do not allow the introduction of light sources through electricity. When power is turned on for lighting, it will cause safety hazards such as direct light, heat energy accumulation, sparks, static electricity, explosions, etc., affecting the safety of people's lives and property. The light introduction device collects outdoor natural light or other light sources through a collector and transmits it into the room through pipes or optical fibers. It can meet indoor lighting requirements without using electricity.
