style="text-indent:25px">隔離/非隔離:一般隔離電源如做成15W，放在LED燈管內，其變壓器體積很大，很難放進去。尤其對T6/T8燈管，幾乎不可能的，所以隔離的一般只能做到10W,超過10W的很少，并且價格很貴。所以，隔離的性價比不高，一般是非隔離的占主流較多，體積可以做得更小，zui小可以做到高8毫米，實際上，非隔離的安全措施做好了，是不存在問題的。電源效率與功率因素:功率因素是有功功率和總功率的比值(C，剩下的無功功率在電網中相互轉化，用戶的電表不會計量無功功率的，對用戶的電表沒任何影響，只是供電局收不到用戶無功功率的錢。江西投光燈批發(fā)不**關于LED顯示屏廠商的走向，也牽連的LED顯屏器件廠家的發(fā)展。</p><div

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，它能夠瞄準任何方向，并具備不受氣候條件影響的結構。主要用于大面積作業(yè)場礦、建筑物輪廓、體育場、立交橋、紀念碑、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]由光學部件、機械部件和電氣部件3部分組成。光學部件主要是反射器和限制光線投光燈的遮光格片。機械部件主要是外殼，以及固定和調整光源位置的調焦機構，固定燈具的支架、基座和帶有角度指示的調整燈具光束投射方向的零件。對絕大部分為密閉式的投光燈，機械部件還有保護玻璃及各種密封圈。根據使用環(huán)境的需要，有的還帶有金屬網罩。性能良好的投光燈還配有空氣過濾器。電氣部件主要是鎮(zhèn)流器、電容器、觸發(fā)器（根據光源需要而設）等。
