Title:
LIGHTING MODULE AND LUMINAIRE
Document Type and Number:
Japanese Patent JP2018092809
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a new structure of a lighting module capable of easily achieving equalization of luminance of a light emission range.SOLUTION: A lighting module 10 includes: a light guide plate 13 having a first main surface 13A for emitting emission light 13L based on emission light 11L which has entered and a second main surface 13B provided on the opposite side from the first main surface, and including a recess 13E including an inside surface 13Ea on the second main surface 13B; and a plurality of light emitting region rows R1-R4 which are the light emitting region rows R1-R4 on which a plurality of light emitting regions 11A arranged so that the emission light 11L enters the inside surface 13Ea of the recess 13E respectively are arrayed, and which are constituted so that light incidence distribution 11st constituted at an incident portion of the light guide plate by the emission light 11L emitted from the plurality of light emission region 11A shows mutually different directions of directivity of forms which do not oppose to or conflict with each other.SELECTED DRAWING: Figure 1
