5、零線帶電了，其實(shí)零線帶電才是關(guān)燈后發(fā)光的zui根本原因。如果開(kāi)關(guān)控制的是火線，使用的是普通墻壁開(kāi)關(guān)，大功率投光燈批發(fā)，還是發(fā)光，就是零線帶電了，大功率投光燈批發(fā)。零線帶電是很普遍的現(xiàn)象，大功率投光燈批發(fā)。如零線接地不好，變壓器三相負(fù)載不平衡，線路太長(zhǎng)，線徑細(xì)，或者零線電流過(guò)大，都會(huì)造成零線帶電。解決辦法:重新進(jìn)行零線接地或進(jìn)行低壓改造。美國(guó)HP公司在1996年三種顏色的LED燈推出的LED汽車(chē)尾燈模組可以隨意組合成各種汽車(chē)尾燈。大功率投光燈批發(fā)</p><div

style="text-indent:25px">下面將以某公司的這款太陽(yáng)能LED大功率路燈為例，分幾個(gè)方面做分析。2.1太陽(yáng)能電池組件選型設(shè)計(jì)要求:廣州地區(qū)，負(fù)載輸入電壓24V功耗34.5W，每天工作時(shí)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(jiǎn)單計(jì)算廣州地區(qū)峰值日照時(shí)數(shù)約為3.424h;(2)負(fù)載日耗電量== 12.2AI)所需太陽(yáng)能組件的總充電電流=1.05×12.2×÷（3.424×0.85）=5.9A在這里，兩個(gè)連續(xù)陰雨天數(shù)之間的設(shè)計(jì)zui短天數(shù)為20天，1.05為太陽(yáng)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。一般來(lái)說(shuō)，按行業(yè)經(jīng)驗(yàn)，在LED顯示屏開(kāi)始裝配至老化72小時(shí)出貨前的失效率應(yīng)不高于萬(wàn)分之三。遼寧投光燈批發(fā)廠家</p><p

style="text-indent:25px">多路恒流輸出供電方式，在成本和性能方面會(huì)較好。也許是以后的主流方向。5.浪涌保護(hù)LED抗浪涌的能力是比較差的，特別是抗反向電壓能力。加強(qiáng)這方面的保護(hù)也很重要。有些LED燈裝在戶外，如LED路燈。由于電網(wǎng)負(fù)載的啟甩和雷擊的感應(yīng)，從電網(wǎng)系統(tǒng)會(huì)侵入各種浪涌，有些浪涌會(huì)導(dǎo)致LED的損壞。因此LED驅(qū)動(dòng)電源要有抑制浪涌的侵入，保護(hù)LED不被損壞的能力。6. 保護(hù)功能電源除了常規(guī)的保護(hù)功能外，zui好在恒流輸出中增加LED溫度負(fù)反饋，防止LED溫度過(guò)高。大功率投光燈批發(fā)</p><p
