Document Type and Number:
Japanese Patent JP7125813
Kind Code:
B2
Abstract:
An object of the present invention is to enable indirect lighting and reduce a left-to-right direction width of a lighting unit body without changing interior fixtures. A lighting unit body 1 comprises: a light source 30; and shaped-members 10, 20, in which a housing portion 22 in which the light source 30 is disposed, reflective surfaces 11, 21 for reflecting light from the light source 30, and an emission outlet 13 for emitting the light from the reflective surfaces 11, 21 are respectively formed in the longitudinal direction. When a position at which the emission outlet is disposed is defined as forward and a direction orthogonal to the longitudinal direction is defined as a front-to-rear direction, and a direction orthogonal both to the longitudinal direction and the front-to-rear direction is defined as a left-to-right direction, then the emission outlet 13 is formed in a front portion of the reflective surfaces 11, 21, and the housing portion 22 is formed in a rear portion of the reflective surfaces 11, 21 directed obliquely rearward at a predefined inclined angle θ on one of left or right side. The predefined inclined angle θ is an angle that inhibits visual observation of the light source from the front of the emission outlet, and the left-to-right direction position at which the light source is disposed is included in the left-to-right direction position at which the emission outlet is located.
