Claims

[Claims for Utility Model Registration] (1) A lighting fixture that is equipped with a light source that emits light that illuminates a room, and a light adjustment member that facilitates changing the position and maintaining a fixed posture in the changed position. (2) The lighting fixture according to claim 1, wherein the light adjusting member is a light-shielding plate removably housed in the frame material of the fixture. (3) The light adjusting member is a reflector having different reflectance on its front and back surfaces, and the reflector has one longitudinal edge on both the inner and outer sides of each of the two light sources pivoted to the shaft body. In the raised position after turning upward, the cross section forms an inverted triangular shape as a whole with the ceiling surface, and becomes a high-brightness reflective surface for the light source, and in the hanging state after turning downward, the light source The lighting fixture according to claim 1, which serves as a low-luminance reflective surface for the lighting system. (4) The light adjustment member is a reflector whose front and back surfaces have different reflectances, and the reflector has one side edge on the lower edge of the plate fixed vertically on the outside of each of the two light sources. It consists of an outer reflector that is pivotally mounted, and an inner reflector that has one edge pivoted to a shaft installed inside the two light sources, and rises after each reflector rotates upward. At the position, each outer reflector overlaps each plate body, and both inner reflectors form a cross-sectional shape, becoming a high-brightness reflecting surface for the light source, and when each reflecting surface is in a hanging state after downward rotation, it becomes a low-brightness reflection surface for the light source. The lighting fixture according to claim 1 of the utility model registration claim, which serves as a reflective surface.
