发明名称 SURFACE LIGHTING SYSTEM
摘要 PROBLEM TO BE SOLVED: To easily perform maintenance such as the replacement of a light source without removing a light conductive plate, and smoothly take in and out a light source cover by holding the light source by arranging the light source cover which can be taken out of and put in the light conductive plate and a holding frame, and arranging a flexible pressing body in the light source cover. SOLUTION: A surface lighting system is used as a back light device of a liquid crystal display device, and has a light conductive plate 2 to illuminate a surface by reflecting the light incident from the side by a reverse reflecting means, a holding frame 3 to surround and hold the light conductive plate 2 and a light source using straight tube lamps respectively interposed between one sides and between the other sides of these light conductive plate 2 and holding frame 3. This light source is held inside a light source cover held so as to be taken out of and put in the light conductive plate 2 and the holding frame 3, and a light source reflector to reflect the light of the light source toward the light conductive plate 2, is also arranged in a light source cover.
