Title:
FLOOR SURFACE LIGHTING FIXTURE
Document Type and Number:
Japanese Patent JP2022154671
Kind Code:
A
Abstract:
To provide a thin bottom surface lighting fixture in which a depth dimension is made to be compact, and which can perform foot lighting and ultraviolet irradiation toward footing.SOLUTION: In a case body mounted below a storage body, a light source unit, a light guide member which is substantially in parallel with a bottom surface, and an LED light source lighting control part are stored. The light source unit includes: a visible light irradiation unit having a visible light LED; and an ultraviolet light irradiation unit on which an ultraviolet LED loading substrate which loads a plurality of ultraviolet LEDs is loaded. The light guide member has, at an end surface, a flat plate shape having an incident surface where emission light from the plurality of ultraviolet light LED light sources enters. Thereby, the ultraviolet light which has entered inside the light guide member emits from the light guide member and radiates the ultraviolet light to the bottom surface. Also, the light radiated from the visible LED radiates the bottom surface. The emission light from the light guide member emits not only from an emission surface on the bottom surface side but also from an end surface, so the bottom surface can be effectively radiated toward the front side of the storage body.SELECTED DRAWING: Figure 2
