In addition, the reflector 3 is configured to have a notch portion 5 in a part of the lower part, and the reflector 4 is configured to have a notch part 6 in an upper part of the reflector 3 so that the turning range of the reflector is increased.
[0012]
Reference numeral 7 denotes a support frame for supporting the reflector 4, which includes a reflector mounting portion 8 and a ring 10 to the ceiling surface 9. The reflector 3 is supported so as to rotate on the support frame rotating shaft 12. Reference numeral 11 denotes a plurality of engaging pieces for engaging the lighting fixture with the ceiling surface, and is configured to have elasticity.
[0013]
The embedded luminaire shown in FIG. 2 shows an embodiment in the case of being used as a cone-type embedded luminaire having a paraboloidal reflecting surface, for example. It rotates horizontally and it is comprised so that the notch part 6 of the reflector 4 may overlap with the notch part 5 of the reflector 3. FIG. If comprised in this way, a clearance gap will not be made between the notch part of the reflector 3 and the reflector 4, and light loss can be reduced.
[0014]
The embedded lighting fixture shown in FIG. 3 shows an embodiment when used as a rotatable universal embedded lighting fixture, and is rotated 180 degrees so that the notch angles of the reflector 3 and the reflector 4 are opposed to each other. Configured. Further, the fixed reflector 3 is tilted and adjusted in a desired irradiation direction. With this configuration, it is possible to illuminate a desired range in a desired direction with a single embedded luminaire.
[0015]
