PURPOSE:To provide a luminaire capable of easy maintenance. CONSTITUTION:A reflector 21 has a rear reflecting mirror 22 and a front reflecting mirror 31 situated on an opening part 35 side from the rear reflecting mirror 22. The rear reflecting mirror 22 is formed independently from the body rear part 16 of a luminaire body 10, and when the mirror surface is deteriorated, only the rear reflecting mirror 22 can be replaced without changing the body rear part 15. Since an infrared shielding film is formed on the rear reflecting mirror 22, infrared rays can be shielded, so that the heating of the luminaire body is minimized, and the maintenance of the luminaire body 10 and the like can be minimized. Since the rear reflecting mirror 22 is formed by a heat- resisting base material independently from the body rear part 16, and the front reflecting mirror 31 is formed on the inner surface of a body front part 30, the heat resistance of the rear reflecting mirror 22 heated by a single tube high pressure discharge lamp HID can be improved. Since the body front part 30 and the body rear part 16 can be opened and closed, and the rear reflecting mirror 22 is attachable and removable, the replacement of the rear reflecting mirror 22 is facilitated. |
