[Lighting method]
Table 1 classifies lighting methods from various viewpoints. First, by light source, efficient, high-intensity, energy-saving lighting using fluorescent lamps and HID lamps (short for high intensity discharge lamps) is preferred in offices, factories, large stores, etc., while high-color-rendering lighting using high-color-rendering fluorescent lamps and metal halide lamps (a type of mercury lamp in which metal halides are added to mercury to improve color and efficiency) is preferred for color inspection work, stores that handle colored items, as well as art galleries and museums.

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. [Taro Kawase]...

[照明方式]
 表1は照明方式をいろいろな観点から分類したものである。まず,光源別では,事務所,工場,大規模店舗などにおいて,蛍光灯やHIDランプ(high intensity discharge lampの略。高輝度放電ランプともいう)による効率本位の高照度,省電力照明が好まれ,色彩の検査作業や色物を扱う店舗のほか美術館,博物館では高演色性の蛍光灯やメタルハライドランプ(水銀に金属ハロゲン化物を添加して色と効率を改善した一種の水銀灯)による高演色性照明が賞用されている。…

【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】。…
