欠点があり、またパルプが高価でもある。Coolray lamps (trade name), which are used for local illumination in surgical procedures, are made by forming an infrared-transmissive and visible light-reflecting film on the inner surface of a reflective glass pulp sealed with a filament. Of the light, visible light is reflected by the reflective film and projected forward, and infrared rays are transmitted through the reflective film and radiated backward, which has the advantage of being able to project light with less infrared rays. However, on the other hand, since infrared rays are emitted backwards, there is a drawback that it is not possible to place items that are susceptible to heat loss at the rear, and the pulp is also expensive.
