投光燈是指定被照面上的照度高于周圍環(huán)境的燈具。又稱聚光燈。通常，它能夠瞄準(zhǔn)任何方向，并具備不受氣候條件影響的結(jié)構(gòu)。主要用于大面積作業(yè)場(chǎng)礦、建筑物輪廓、體育場(chǎng)、立交橋、紀(jì)念碑、公園和花壇等。因此，幾乎所有室外使用的大面積照明燈具都可看作投光燈。投光燈的出射光束角度有寬有窄，變化范圍在0°～180°之間，其中光束特別窄的稱為探照燈。投光燈[1]由光學(xué)部件、機(jī)械部件和電氣部件3部分組成。光學(xué)部件主要是反射器和限制光線投光燈的遮光格片。機(jī)械部件主要是外殼，以及固定和調(diào)整光源位置的調(diào)焦機(jī)構(gòu)，固定燈具的支架、基座和帶有角度指示的調(diào)整燈具光束投射方向的零件。對(duì)絕大部分為密閉式的投光燈，機(jī)械部件還有保護(hù)玻璃及各種密封圈。根據(jù)使用環(huán)境的需要，有的還帶有金屬網(wǎng)罩。性能良好的投光燈還配有空氣過(guò)濾器。電氣部件主要是鎮(zhèn)流器、電容器、觸發(fā)器（根據(jù)光源需要而設(shè)）等。故只要LED器件品質(zhì)保證、工作電流合適、PCB散熱設(shè)計(jì)合理、顯示屏生產(chǎn)工藝嚴(yán)謹(jǐn)。</p><div
