Document Type and Number:
Japanese Patent JP6822204
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a lighting fixture which can efficiently irradiate an irradiation surface and hardly causes oppressive feeling.SOLUTION: A lighting fixture comprises a mounting plate, a main body, a first light source and a second light source. The mounting plate is mounted on a first surface. The main body is mounted on the mounting plate. The first light source has a first substrate extending in a longitudinal direction of the main body and a plurality of first light-emitting devices arranged so as to irradiate the first surface in the longitudinal direction of the main body. The second light source has a second substrate extending in the longitudinal direction of the main body and a plurality of second light-emitting devices arranged so as to irradiate a second surface different from the first surface in a longitudinal direction of the second substrate. The first light source, as viewed in the longitudinal direction of the main body, is arranged on the main body so as to irradiate the first surface in a direction in which a first angle formed by an irradiation direction and the first surface is an acute angle. The second light source, as viewed in the longitudinal direction of the main body, is arranged on the main body so as to irradiate the second surface in a direction in which a second angle formed by the irradiation direction and the second surface is an acute angle.SELECTED DRAWING: Figure 2
