PURPOSE:To facilitate the positioning of a lamp by providing a reflecting plate with a peep hole and an index facing the peep hole, and arranging a means which positions the lamp between the hole index. CONSTITUTION:A screw 16 is adjusted while a nut 23 is loosened to position the lamp 2 relatively to the reflecting plate 1. In this case, the index 4 is viewed through the peep hole 3 of the positioning means 5 to set the focus of the reflecting plate 1 on the line connecting them, and consequently the center of the light emitting part of the lamp 2 is aligned to the line to position the lamp 2 relatively to the reflecting plate 1. Another pair of the peep hole 3 and index 4 are provided at right angles to said pair to position the lamp along the line, and the lamp 2 is stored in the reflecting plate 1 while aligned to the focus of the reflecting plate 1. |
