PROBLEM TO BE SOLVED: To simply replace a fluorescent tube by forming a lighting unit with a light guide body provided with a light equalizing means, the fluorescent tube arranged at the side face section of the light guide body, a resin case holding the light guide body and fluorescent tube, and a resin cover pressing and holding the light guide body and fluorescent tube, and connecting the resin case and resin cover with a hinge section to integrally mold them. SOLUTION: A light equalizing pattern (light equalizing means) is formed on the back face of a light guide body 1, and a reflector 2 is arranged on its face. A diffusing plate 3 is arranged on the opposite face side (surface side) of the light guide body 1, and a fluorescent tube 4 is arranged at the side face section of the light guide body 1. A resin case 5 holding the light guide body 1 and fluorescent tube 4 and a resin cover 6 pressing and holding the light guide body 1 and fluorescent tube 4 are connected by a hinge section 7 and integrally molded. The resin case 5 and resin cover 6 are fixed by screws 9 in the pressed state. There is no reflecting film enveloping the fluorescent tube 4, and the fluorescent tube 4 can be simply replaced. |
