PURPOSE:To provide a lighting equipment which can stably control infrared rays by means of one receptor. CONSTITUTION:A reflector 11 is provided for the outer circumference of a base pedestal 8 at the ceiling surface 1 side, and a receptor 6 and an indirect lighting illuminant 10 for infrared rays are provided for the base pedestal 8 while being faced to the reflector 11. By this constitution, infrared signals going upward reach the receptor 6 via the reflector 11, and light from the illuminant 10 is turned out to be indirect light. This constitution enables infrared rays to be stably controlled regardless of the finishing specification of a ceiling surface 1, enables lighting to be indirect while light distribution characteristics is excellent, and also enables the aforesaid functions to be provided inexpensively. |
