style="text-indent:25px">下面將以某公司的這款太陽能LED大功率路燈為例，分幾個方面做分析。2.1太陽能電池組件選型設(shè)計要求:廣州地區(qū)，負(fù)載輸入電壓24V功耗34.5W，每天工作時數(shù)8.5h，保證連續(xù)陰雨天數(shù)7天。(I)廣州地區(qū)近二十年年均輻射量107.7Kcal/cm2，經(jīng)簡單計算廣州地區(qū)峰值日照時數(shù)約為3.424h;(2)負(fù)載日耗電量== 12.2AI)所需太陽能組件的總充電電流=1.05×12.2×÷（3.424×0.85）=5.9A在這里，兩個連續(xù)陰雨天數(shù)之間的設(shè)計zui短天數(shù)為20天，1.05為太陽能電池組件系統(tǒng)綜合損失系數(shù)，0.85為蓄電池充電效率。</p><p style="text-indent:25px">在一些24小時連續(xù)工作的場地，例如地下停車場、24小時加班生產(chǎn)的工廠等地方。節(jié)電也是十分重要的。如上所述，- -根T8的LED日光燈大約可以節(jié)省20瓦電，一年下來就可以節(jié)省20x365x24/1000=175.2度電。假如以每度電0. 7元計算，那么一年下來，可以節(jié)省電費122.64元，兩年下來，就可以節(jié)省出這根LED日光燈的成本。以后所節(jié)省的電費就成為純收益了。所以現(xiàn)在國外有一種稱之為EMC (能源管理合同Energy ManagementContract)作法。就是由一家財團或銀行出資。替一個地下停車場或商場**安裝LED日光燈，但是要向業(yè)主收取所有節(jié)省下來的電費，協(xié)議有效期可能為5年。只要2年以后，就可以回收所有投資，第三年開始，所有節(jié)省下來的電費就變成是純收益了。這是一個十分有利的投資項目。國內(nèi)也開始有人這樣做了。更何況按照Haitz定律，LED的價格每十年將降低十倍!顯示屏價格比重的70%，所以說LED器件可以決定LED顯示屏質(zhì)量的優(yōu)劣。</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(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。如果是，這種情況也容易造成Led燈珠不亮，解決方法是選擇合適的恒流的電源。山東白光投光燈</p><p
