Title:
ILLUMINATING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2011/001518
Kind Code:
A1
Abstract:
Provided is an illuminating apparatus having high irradiation efficiency and excellent appearance. The illuminating apparatus is composed of a translucent planar light emitting module, and a switching plate arranged on the rear surface of the planar light emitting module. Since the switching plate is switchable to be in a light blocking state and a light transmitting state, light can be guided, for instance, in one direction by having the switching plate in the light blocking state when the planar light emitting module is emitting light, and irradiation efficiency is prevented from deteriorating.
