<P>PROBLEM TO BE SOLVED: To provide a reflective type LED lighting system of lightweight, saving resources and with various design properties. <P>SOLUTION: As the LED lighting system, an indirect lighting system of a bulb type, a straight tube type or a surface type with a number of LEDs arranged, or the same type using a light guide body are in practical use. In the reflective type LED lighting system, an LED light source is arranged at an outer peripheral part of the light guide body, the reflective type LED lighting system has a lightweight light guide cavity combined with the LED light source and a reflective body with a rough surface formed and a light-diffusion translucent plate as basic elements, with weight reduced without using an acrylic resin light guide body, with indirect illumination friendly to user's eyes, and with one-side or both-side light emission type. The light-diffusion translucent plate is arranged between the light source and a lighting plate, the direct type lighting system in which the LED light linearly reaches the eyes has the same visual feeling as the reflective type. <P>COPYRIGHT: (C)2012,JPO&INPIT |
