LUMINAIRE USING LIGHT-EMITTING ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide an luminaire using a light-emitting element which allows an illumination direction to be adjusted freely.

SOLUTION: The luminaire is constituted of a fixture body having a pair of sealing bodies 50 to fix light sources formed of a plurality of light-emitting elements into a protective cylinder 40, and a base 10B with electrode pins 62 arranged on both end face sides of each seal. Between the seal 50 and the base 10B, an illumination direction adjusting member 80 is arranged which adjusts a mounting position of the seal against the base. The adjusting member 80 is composed of a rotating cylinder 80A fixed inside the base and a coupling member 80B to elastically couple this rotating cylinder with the seal, and the base is rotated to adjust a position of the rotating cylinder against the seal, thereby adjusting the illumination direction (irradiation direction) of the light sources sealed in the seal.
