Title:
LINEAR LIGHT IRRADIATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/124037
Kind Code:
A1
Abstract:
To improve the uniformity of illuminance that runs along the longitudinal direction of linear light, and to use, as linear light, light in a state in which the intensity of the light emitted from a filament is maintained at a high level. The present invention is provided with a first light source row L1 and a second light source row L2 in which a plurality of light sources 10 are disposed in a row, the light sources 10 being configured such that a terminal 14 connected to a socket 20 extends from a light-emitting unit 12 having a filament 11. The light sources 10 of the first light source row L1 and the light sources 10 of the second light source row L2 are disposed alternatingly along the row direction in a state in which the light-emitting units 12 are oriented toward the other light source row, and the filaments 11 of the light sources 10 of the two light source rows L1, L2 are positioned in a collinear manner.
