style="text-indent:25px">和熒光燈相比大約可以節(jié)省一半以上的電，也就是說(shuō)采用一個(gè)18瓦的LED日光燈可以取代一個(gè)36瓦的熒光燈。不僅如此，LED日光燈還有很多其他優(yōu)點(diǎn):4.壽命長(zhǎng):一個(gè)仔細(xì)設(shè)計(jì)的LED日光燈的壽命可以達(dá)到5萬(wàn)小時(shí)。而一個(gè)熒光燈的壽命通常只有5, 000小時(shí)(有些國(guó)產(chǎn)的熒光燈壽命只有300小時(shí))。二者相差將近10倍。比較好的長(zhǎng)壽命日光燈也只有10,000小時(shí)，二者也還相差5倍。5.不含汞，無(wú)污染。我們知道，熒光燈都含有汞。36mm熒光燈中含有25-45mg的汞，26mm (T8) 中含有20mg的汞。</p><p style="text-indent:25px">度發(fā)光的，而在反方向發(fā)出的光就沒(méi)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(lái)，一般來(lái)說(shuō)，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(jué)得120度發(fā)光角度窄了一點(diǎn)，不過(guò)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(lái)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失效率：由于全彩顯示屏由上萬(wàn)甚至幾十萬(wàn)組紅、綠、藍(lán)三種LED組成的像素點(diǎn)組成。</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(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。盡量不要買那些的電源。以防止因電源電流過(guò)大將Led燈珠擊穿而造成燈珠不亮燈具。遼寧1688投光燈led</p><p
