ある。The heater 14 arranged in the recess 10 of the reflection plate 9 is formed in a ring shape, and is attached by a support piece 15 suspended from the reflection plate 9 to emit heat downward. Here, the shape of the curved surface of the reflection plate 9 of the recess 10 is a parabolic surface, and the heater 14 is arranged at the focal position. Also, a straight line connecting the heater 14 and the opening edge 10a inside the recess 10
A shaded portion (hatched portion in FIG. 1) is formed between (a) and the flat portion of the reflection plate 9, and this straight line and the lower portion of the lamp 11
It is arranged so as to be located above (a). Therefore,
The direct light (heat) from the heater 14 does not reach the lamp 11 so that the heat from the heater 14 is not directly affected by the lamp 11. Further, since the lamp 11 projects from the central flat portion of the reflector 9, the reflector 9 can be effectively used for light distribution control. In addition, this lighting equipment, lamp 1
