PROBLEM TO BE SOLVED: To provide a plate lighting system which consumes low power, is front-end type, and has high visibility in either case of its lighting and non- lighting. SOLUTION: A reflector 3 is placed in a light-transmitting plate 1 such that the reflector 3 is diagonal to the flat plane of the light-transmitting plate, and a light source 2 is arranged at an end 4 of the plate. This lighting system is placed in front of a lightened object, emits a light beam to the light beam to the lightened object, and transmits the light reflected on the lightened object without diffracting much of the light. When the illumination is not lightened, the system transmits external light and the external light reflected on the lightened object without diffracting much of the light. The lighting system can use a fluorescent tube, a light emitting diode(LED), or a bulb as a light source, and therefore consuming power is easily reduced. |
