Document Type and Number:
WIPO Patent Application WO/2013/133147
Kind Code:
A1
Abstract:
Provided is an illuminating apparatus, which is thin, and uniformly emits light.
This illuminating apparatus is provided with: a substrate (20); a plurality of semiconductor light source units (30), which are disposed in the form of lattice on the substrate (20); and a light diffusion member (40), which is provided by being spaced apart from the semiconductor light source unit (30). The illuminating apparatus is formed such that a thinning coefficient T=h/d satisfies the formula of 0.4≤T≤1.0, where the intervals at which the semiconductor light source units (30) are disposed is represented by d[mm], and the distance between the semiconductor light source units (30) and the light diffusion member (40) is represented by h [mm].
