Several different light sources for searchlights

There are many kinds of searchlight sources, such as the following:

最简单也是耗能较高的是白炽灯，工作原理就是电-->热-->光

    The simplest and most energy-consuming is the incandescent lamp. Its working principle is electricity - > heat - > light.

自镇流灯,和镇流器的灯相似,不同之处是它的镇流元件在灯泡里,灯口与白炽灯一样,安装简便,效率要比白炽灯高;

    Self-ballast lamp is similar to ballast lamp. The difference is that its ballast element is in the bulb. Like incandescent lamp, the lamp port is easy to install and has higher efficiency than incandescent lamp.

镇流器灯: 有高压汞灯/高压钠灯.... 工作原理与日光灯相同,有镇流器限流,辅助启动器启动,效率比自镇流灯要高,目前街道路灯大部分都是这种灯,

    Ballast lamp: high pressure mercury lamp/high pressure sodium lamp.... The working principle is the same as fluorescent lamp, with ballast current limiting, auxiliary starter starting, the efficiency is higher than self-ballast lamp. At present, street lamp is mostly this kind of lamp.

碘钨灯: 用含碘的灯管内装钨丝, 长管状,电极在两端, 工作原理与白炽灯相同,但功率高,发热大,当然亮度也挺大的.

    Tungsten iodide lamp: Tungsten filament is installed in the iodine-containing lamp tube with long tubular shape and electrodes at both ends. Its working principle is the same as that of incandescent lamp, but it has high power, high heat and of course high brightness.

大功率节能灯, 不用说灯角与白炽灯相同,安装简便,效率也比较高,缺点是功率不太大

    High-power energy-saving lamps, needless to say, have the same angle as incandescent lamps. They are easy to install and have high efficiency. The disadvantage is that the power is not too high.

公园里景观的探照灯及防空用探照灯我没接触过, 可能还有其它形式!

    I haven't touched the searchlights of the park landscape and the searchlights for air defense. There may be other forms of searchlights as well! _________

照明的目的是按人的需求来做的, 一般设计时首先要考虑的能否满足工作/生产的需要, 然后才考虑是否节能.

    The purpose of lighting is to meet people's needs. In general, the first thing to consider when designing is whether it can meet the needs of work/production, and then whether it can save energy.
