指向性を有する。Next, the function of this light bulb will be explained. Terminal pin (8)
When electricity is applied to (8), the filament (7) emits infrared light as well as visible light. Of these lights, the infrared light is reflected by the infrared reflective film (3) and returns to the pulp (1), and the visible light is converted into infrared light. The light passes through the reflective film (3) and is emitted to the outside. Therefore, in this embodiment, since the filament (force) has an oblate shape, most of the emitted light is emitted from the oblate planes (73) and (73). , (73) are directly opposite to the flat parts (2) and (2) of the pulp (1), respectively, so the infrared rays reflected from the infrared reflective film (3) of the flat parts (2) and (2) are greatly affected. Partial filament oblique plane (73), (
73) and heats the filament to improve luminous efficiency. In this way, in the light bulb of this embodiment, most of the infrared rays emitted from the filament effectively return to the filament, so the luminous efficiency is extremely high, and the visible light is directional.
