摘要：PURPOSE:To have lighting-up of a lamp with the electric power saved, by restricting the gap ratio of a filament coil of a halogen electric bulb equipped with an infrared reflex film into a certain range, and by improving the absorptiveness of infrared rays reflected by the infrared reflex film. CONSTITUTION:A filament 3 consisting of double coil is accommodated in a bulb 1. Infrared reflex films 9 are formed over the inner surface and outer surface of the bulb 1. The film 9 admits penetration of visual light and reflects the major part of infrared rays. The filament 3 is formed such that the gap ratio s=1-d/D, where d reprents the dia. of coil element wire of a primary coil while D the distance between centers of adjoining wirings, and the range of (s) is t between 0.3 and 0.7. The filament 3 emits light, and visible wavelength beam and infrared rays are radiated. Among them, the infrared rays are reflected by the film 9 and returned to the filament 3. The absorptiveness of the infrared rays reflected by the film 9 can be improved by tting the valve of the gap ratio (s) within the above-mentioned range, and thus the heating electric power can be saved.
