Title:
SURFACE ILLUMINATION METHOD USING POINT LIGHT SOURCE, LINEAR LIGHT SOURCE DEVICE, AND SURFACE ILLUMINATION DEVICE USING LINEAR LIGHT SOURCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/030856
Kind Code:
A1
Abstract:
Disclosed is a surface illumination device provided with a point light source (I) having high directivity, a linear light conversion means (II) for converting light from the point light source into linear light, a linear light diffusion means (III) for diffusing the linear light, and a planar illumination means (IV) which is irradiated with the diffused light to emit a planar illumination light, wherein light from the point light source (I) is converted into linear light by the linear light conversion means (II), the converted linear light is diffused in predetermined directions by the linear light diffusion means (III), and the planar illumination means (IV) is irradiated with the diffused light to emit planar light.
