Title:
LIGHT RADIATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2002/085243
Kind Code:
A1
Abstract:
A light radiating device capable of curing a photopolymerization material by condensing light from light radiating means without using a light condensing means such as an optical system, comprising a portable hand piece and a base part for placing the hand piece thereon when the hand piece is not used, the hand piece further comprising the plurality of light radiating means with a directivity and a holding means holding the plurality of light radiating means at specified angles so that the light outputted from the plurality of light radiating means can be condensed, the holding means further comprising a body part and a plurality of holes formed in the body part, wherein the body part may be platy or curved one and, when fluid with an excellent heat conductivity is stored in a space surrounded by a substrate, holding means, and members, the heat radiation efficiency of a light source can be increased.
