<P>PROBLEM TO BE SOLVED: To provide a lighting device capable of expanding light distribution with a simple structure. <P>SOLUTION: The lighting device 100 includes an LED module 1 having directionality and a translucent cover 8 which houses the LED module 1 inside and transmits light from the LED module 1. In the translucent cover 8, at least a portion of which has light diffusion performance, at least a portion of light emitted from the LED module 1 is primary reflected and the primary reflected light is further reflected by a reflector 7 installed on the opposite side in light-emitting direction of the LED module 1 toward the direction different from the light-emitting direction of the LED module 1. As a result, by a simple structure in which at least a portion of the translucent cover 8 has a light diffusion performance and the reflector 7 formed properly is installed on the opposite side in light-emitting direction of the LED module 1, light distribution can be expanded. <P>COPYRIGHT: (C)2010,JPO&INPIT |
