熒光燈（手持式）Fluorescentlamp(hand-held)熒光燈，也稱為日光燈

詳細(xì)介紹

熒光燈（手持式）

Fluorescent lamp (hand-held)

熒光燈，也稱為日光燈。傳統(tǒng)型熒光燈即低壓汞燈，是利用低氣壓的汞蒸氣在通電后釋放紫外線，從而使熒光粉發(fā)出可見光的原理發(fā)光，因此它屬于低氣壓弧光放電光源。

Fluorescent lamp, also known as fluorescent lamp. The traditional fluorescent lamp, i.e. low-pressure mercury lamp, uses the principle that low-pressure mercury vapor releases ultraviolet rays after being electrified, so that fluorescent powder emits visible light, thus it belongs to a low-pressure arc discharge light source.

任何情況下，都應(yīng)采用三基色熒光燈，不應(yīng)再選用鹵粉熒光燈。三基色燈管具有光效高、顯色好、壽命更長的優(yōu)勢。雖價格貴（約貴一倍），但由于其光效高，不僅節(jié)能效果好，降低了運行成本；而且由于使用燈數(shù)減小，節(jié)省了燈具及鎮(zhèn)流器的費用，反而使照明系統(tǒng)的總初建費用降低。

In any case, tricolor fluorescent lamps should be used instead of halogen fluorescent lamps. Tricolor lamps have the advantages of high luminous efficiency, good color rendering and longer service life. Although the price is expensive (about twice as expensive), due to its high light efficiency, it not only has good energy saving effect, but also reduces the operation cost. In addition, as the number of lamps used is reduced, the cost of lamps and ballasts is saved, and the total initial construction cost of the lighting system is reduced.

采用大功率燈珠：在功能照明場所（除外裝飾性要求），其光效更高。

Using high-power lamp beads: in functional lighting places (except for decorative requirements), its light efficiency is higher.

一般情況宜采用中色溫?zé)艄埽汗庠吹纳恚ㄓ孟嚓P(guān)色溫表示）選擇，除建筑色彩特殊要求外，一般可根據(jù)照度高低確定：簡單說，高照度（>750lx）宜用冷色溫（高色溫），中等照度（約200～1000lx）用中色溫，低照度（≤200lx）用暖色溫（低色溫）。因為暖色溫光在低照度下使人感到舒適，而在高照度下就感到燥熱；而冷色溫光在高照度下感到舒適，在低照度時感到昏暗、陰冷。多數(shù)場所的照度在200～750lx之間，用中色溫光源更好；而且中、低色溫的熒光燈光效比高色溫?zé)舾撸灿欣?jié)能。

In general, medium color temperature lamps should be used: the color meter of the light source (expressed by correlated color temperature) should be selected. in addition to the special requirements of building color, it can be generally determined according to the illuminance level: in brief, cold color temperature (high color temperature) should be used for high illuminance (> 750lx), medium color temperature should be used for medium illuminance (about 200 ~ 1000 LX), and warm color temperature (low color temperature) should be used for low illuminance (≤200lx). Because warm color and warm light make people feel comfortable under low illumination, but feel hot and dry under high illumination. However, cold color temperature light feels comfortable under high illumination and dim and cold under low illumination. The illuminance in most places is between 200 and 750 Lx, and it is better to use medium-temperature light source. Moreover, fluorescent lamps with medium and low color temperatures have higher luminous efficiency than lamps with high color temperatures, which is also beneficial to energy conservation.
