Title:
IRRADIATION UNIT AND IRRADIATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/180902
Kind Code:
A1
Abstract:
The present invention enhances peak illuminance and enables space saving. An irradiation unit (30) that applies light to a predetermined irradiation position (T) is provided with: a pair of mounting substrates (52) which has light emitting parts (60) including ultraviolet LEDs, respectively and which is disposed such that the light emitting parts (60) oppose each other; and a pair of first reflection surfaces (55) and a pair of second reflection surfaces (57) which are disposed at such opposing positions that the paired first reflection surfaces (55) oppose the light emitting parts (60) of the mounting substrates (52), respectively, and the paired second reflection surfaces (57) oppose the light emitting parts (60) of the mounting substrates (52), respectively, and which perform light distribution control of light of the light emitting parts (60) positioned at the opposing positions. The second reflection surfaces (57) are located closer to the predetermined irradiation position (T) than the first reflection surfaces (55) are, and are each spaced from the light emitting part (60) at its opposing position, with respect to the first reflection surfaces (55), so as to be disposed on the other light emitting part (60) side. Each second reflection surface (57) is disposed with a space (Q) provided between the second reflection surface (57) and a corresponding one of the first reflection surfaces (55). Light, which enters each second reflection surface (57) from the light emitting part (60) at its opposing position, enters the second reflection surface (57) through the space (Q).
