Title:
ILLUMINATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/230540
Kind Code:
A1
Abstract:
The present invention is an illumination device comprising light sources (20) in which filaments (21) are used, wherein the illumination device (100) comprises: a plurality of light sources (20) with which control of the light-gathering properties and of the uniformity of light irradiated on an object is facilitated and parts that are to be connected, such as sockets (20B), can be protected from heat, the plurality of light sources (20) being aligned in one row or a plurality of rows and being designed to flatten the intensity distribution of light irradiated on the object; and a casing (10) that accommodates the light sources (20) and has a light extraction port X formed therein for extracting light from the light sources. The light sources (20) have: light-emitting parts (20A) in which the filaments (21) are accommodated in tubular accommodating bodies (22); and parts that are to be connected, such as the sockets (20B), to which the light-emitting parts (20A) are connected. The illumination device (100) furthermore comprises shielding members (60) disposed in an orientation in which light emitted from the outer circumferential surfaces (221) of the accommodating bodies (22) can be extracted from the light extraction port X, the shielding members (60) covering at least part of the sockets (20B) and shielding the light emitted from the light-emitting parts (20A) toward the sockets (20B).
