Abstract (en)
[origin: JPH0244604A] PURPOSE: To provide a device having high permeability in relation to the visible light beam and having high reflectivity in relation to the infrared ray by providing a reflector in a light source provided with one light emitting tube, and providing an interference filter body formed of multiple layers at a part of an outer surface of the light emitting tube. CONSTITUTION: A part of the visible light beam emitted from an interference layer 3 directly arrives a reflector 7, and a part thereof arrives there through a radiation turning mirror 12, and the light is reflected in a primary lighting range. Namely, the infrared ray outgoes through an unstratified socket part 5 of a lamp bulb, and led out from this optical system through an opening 8 provided in a reflecting system 11 or an infrared ray transmission part provided in the reflecting system 11, and directly or indirectly arrives a heat absorber. In the case of the indirect radiation of the heat absorber, the infrared ray is led to the heat absorber through a radiation turning mirror 12. A spherical head 4 of a light emitting tube 1 can be arranged adjacent to the opening 8 of the reflecting system 11 or the infrared ray transmission part by arranging the light emitting tube while turning it at 180 degree.
