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)場礦、建筑物輪廓、體育場、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。 </p><p style="text-indent:25px">而效率(y則是輸出功率和輸入功率的比值，即輸出功率(輸出LED的電壓*輸出電流/輸入功率，這個(gè)參數(shù)尤為重要，涉及到產(chǎn)品和用戶的利益，如果效率低就意味著輸入功率有很大一部分轉(zhuǎn)化為熱量散發(fā)出來;如果是裝在燈管內(nèi)就會(huì)產(chǎn)生一個(gè)很高的溫度，再加.上我們LED的一個(gè)光效比所散發(fā)熱.量，就會(huì)疊加產(chǎn)生更高的溫度。而我們的電源內(nèi)部所有電子零件的壽命都會(huì)隨溫度的上升而縮短.效率高，轉(zhuǎn)化成光的效率就高，而且電源和燈管的發(fā)熱就會(huì)減少，相當(dāng)于省電，產(chǎn)品性能和壽命會(huì)提高。所以說效率是決定電源壽命zui根本的因數(shù)，效率不能太低，否則消耗在電源上的熱量太大。一般在0.8-0.9以上就可以了。功率因素，效率這兩個(gè)指標(biāo)有時(shí)會(huì)檢查是否因led燈珠引腳虛焊，焊接時(shí)溫度過高。</p><div

style="text-indent:25px">度發(fā)光的，而在反方向發(fā)出的光就沒有什么用處。所以熒光燈通常采用一個(gè)白色的燈罩，可以把相當(dāng)一部分的反向光反射回來，一般來說，熒光燈的燈具效率大約只有70%。而LED日光燈則是120度發(fā)光的，所以全部光都是有效光。雖然有時(shí)候也會(huì)覺得120度發(fā)光角度窄了一點(diǎn)，不過大多數(shù)情況下還是夠用的。而且這個(gè)發(fā)光角度也是可以根據(jù)需要來加以調(diào)整的。前面提到Philips的T8熒光燈的發(fā)光效率為721m/W，36W的熒光燈一共發(fā)出2592流明，但是燈具效率只有70%，所以有效的流明數(shù)為1814.4如存在不正確操作引起燈珠不亮，則重新焊接led燈珠一般即可解決。上海批發(fā)投光燈具</p><p

T8普通日光燈三防燈具; T8三防燈是一款應(yīng)用比較廣的燈具，是針對(duì)普通日光燈來設(shè)計(jì)的，具有通用性，也是目前為應(yīng)用zui多的日光燈管。3.LED三防燈具，這是從T8三防燈具改裝過來的。湖南防水投光燈廠家</p></p><br /><p>文章來源地址:
