荧光灯(手持式)

Fluorescent lamp (hand-held)

荧光灯,也称为日光灯。传统型荧光灯即低压汞灯,是利用低气压的汞蒸气在通电后释放紫外线,从而使荧光粉发出可见光的原理发光,因此它属于低气压弧光放电光源。

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.

任何情况下,都应采用三基色荧光灯,不应再选用卤粉荧光灯。三基色灯管具有光效高、显色好、寿命更长的优势。虽价格贵(约贵一倍),但由于其光效高,不仅节能效果好,降低了运行成本;而且由于使用灯数减小,节省了灯具及镇流器的费用,反而使照明系统的总初建费用降低。

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.

采用大功率灯珠:在功能照明场所(除外装饰性要求),其光效更高。

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

一般情况宜采用中色温灯管:光源的色表(用相关色温表示)选择,除建筑色彩特殊要求外,一般可根据照度高低确定:简单说,高照度(>750lx)宜用冷色温(高色温),中等照度(约200~1000lx)用中色温,低照度(≤200lx)用暖色温(低色温)。因为暖色温光在低照度下使人感到舒适,而在高照度下就感到燥热;而冷色温光在高照度下感到舒适,在低照度时感到昏暗、阴冷。多数场所的照度在200~750lx之间,用中色温光源更好;而且中、低色温的荧光灯光效比高色温灯更高,也有利节能。

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.
