する。BACKGROUND OF THE INVENTION Conventional infrared light bulbs can be roughly divided into bulb-type bulbs with a built-in reflector and tube-type infrared bulbs with a tungsten filament or nichrome wire sealed in a quartz tube. Quartz tubes can be used at high temperatures, making it possible to create small, high-power infrared light bulbs. Those using a tungsten filament are designed to have a temperature of 2,000 to 2,500 when lit at the rated voltage, and reach the rated filament temperature in a few seconds to more than ten seconds after electricity is applied, and the near-infrared rays determined by the filament temperature. radiate. The spectral distribution of the radiation coming out of the filament follows the emission side of the blank. Radiation in a wavelength range that is transmitted by the quartz outer tube is directly radiated outside the tube, and radiation in a wavelength range that is not transmitted is absorbed by the quartz tube and acts as a temperature increase.

する。Infrared light bulbs containing nichrome wire have a filament temperature of about 800 to 1300, and the emitted infrared rays are biased toward long wavelengths because the temperature is lower than that of the tungsten filament. Nichrome wire has a larger heat capacity than tungsten filament, so it takes several minutes to reach a predetermined temperature after electricity is applied.

It is said. However, since this also has a large heat capacity, it has the disadvantage that it takes several minutes to reach a predetermined temperature after energization.

要である。Currently, metal oxides, ceramics, etc. are known as materials that emit far-infrared rays, and there is no need to specify them. When attaching or coating the far-infrared emitting material to the entire surface or part of the surface of a quartz tube-type infrared light bulb, the far-infrared emitting material must be treated so that it comes into close contact with the surface of the quartz tube, or it must have an expansion coefficient that is equal to or very close to the coefficient of thermal expansion of quartz. It is necessary to apply a far-infrared emitting material with a certain rate.
密着させる方法としてはプラズマ溶射の方法などが有効
である。Plasma spraying is an effective method for achieving close contact.

も暖かく感じることになる。The action of infrared rays is absorbed by a material at a depth determined by the wavelength of the infrared rays and the transmittance of the material, and is converted into thermal energy, resulting in an increase in the temperature of the area. The infrared rays that are irradiated and absorbed by the human body also generate heat energy that causes the temperature of tissues to rise, giving the body a sensation of warmth. When the radiant energy exceeds a certain amount, it causes a burning sensation. In particular, in the human body, there is a hot spot (nerve papilla that feels thermal sensation) 2.6 to 5 mm below the skin surface, so if infrared rays are absorbed near the hot spot, the thermal sensation becomes sensitive. Since the transmittance of infrared rays to the skin differs depending on the wavelength of the infrared rays, by selecting an appropriate wavelength of infrared rays, a person will feel warm even with the same irradiance.
赤外線の放射波長を適切に選ぶことが、加熱や温熱感を
効果よくもたらすことができる。Appropriate selection of the wavelength of infrared radiation can effectively produce heating and thermal sensations.
