… From [Discharge Lamp]…In recent years, high-pressure mercury lamps, metal halide lamps, and high-pressure sodium lamps are collectively called HID lamps. This is an abbreviation of high intensity discharge lamp, which is translated as high-intensity discharge lamp or high-pressure discharge lamp. HID lamps are characterized by their small size, high output, high efficiency, and long life. … From [Metal halide lamps]...The reason why luminous metals are used in the form of halides is that (1) to obtain metallic luminescence, the vapor pressure inside the discharge tube must be relatively high, but the vapor pressure is higher for halides than for the metal alone, and (2) for metals such as alkali metals that react easily with high-temperature quartz glass when used alone, the reaction can be suppressed by making them into halides. Metal halide lamps are a type of so-called HID lamps (short for high intensity discharge lamps), and are small and can produce high output.

… 【放電灯】より…近年,高圧水銀灯,メタルハライドランプ,高圧ナトリウムランプをまとめてHIDランプと呼ぶことがある。これはhigh intensity discharge lampの略で,高輝度放電ランプまたは高圧放電ランプと訳されている。HIDランプは小型で高出力,高効率,長寿命が特長である。… 【メタルハライドランプ】より…発光金属をハロゲン化物の形で用いるのは,(1)金属の発光を得るには放電管内の蒸気圧がある程度高くなければならないが,金属単体の場合よりハロゲン化物のほうが蒸気圧が高くなる,(2)アルカリ金属のように単体では高温の石英ガラスと反応しやすい金属も,ハロゲン化物にすることにより,反応を抑制できるなどの理由による。 メタルハライドランプはいわゆるHIDランプ(high intensity discharge lampの略で高輝度放電ランプと呼ばれる)の一種で,小型で高出力が得られる。【川瀬 太郎】。… ※「high intensity discharge lamp」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
