LED panel light is composed of backlight module, light, driving, frame structure and diffuser plate. Light irritates from both sides or edges of the light guide material and changes the light advancing direction after the processing of light interference pattern. Most of the interfered light will shine out directly from the diffuser plate and only a small amount of the light will be reflected on the reflective material fraction for a second secondary reflector. All these light shines out as far as possible to achieve the illumination purpose.
