LIGHTING DEVICE AND EMERGENCY LIGHTING DEVICE

摘要

PROBLEM TO BE SOLVED: To obtain an ideal light-distribution curve with the small parts count.

SOLUTION: A plurality of light-emitting bodies (LEDs inside an LED package 110) irradiate an area nearly in the same direction. A reflecting body (a reflector 120) is located at a position surrounded by the plurality of light-emitting bodies with its side faces reflecting light. Light emitted by the light-emitting bodies is partly reflected on the side faces of the reflecting body, and a combination of reflected light and direct light emitted from the light-emitting bodies make up an ideal distribution light similar to a batwing-shaped one.
