style="text-indent:25px">這種現(xiàn)象屢見不鮮。有些小企業(yè)采用手工焊接，使用40瓦普通烙鐵，焊接溫度無法控制，烙鐵溫度在300-400°℃以上，過高的焊接溫度也會造成死燈，LED引線在高溫下膨脹系數(shù)比在150℃左右的膨脹系數(shù)高好幾倍，內(nèi)部的金絲焊點(diǎn)會因為過大的熱脹冷縮將焊接點(diǎn)拉開，造成死燈現(xiàn)象。2、LED燈內(nèi)部連線焊點(diǎn)開路造成死燈現(xiàn)象的原因分析2.1封裝企業(yè)生產(chǎn)工藝不建全，來料檢驗手段落后，是造成LED死燈的直接原因，一般采用支架排封裝的LED,支架排是采用銅或鐵金屬材料經(jīng)精密模具沖壓而成江西led投光燈鎮(zhèn)流器法向方向白平衡再好的顯示屏，如果LED的角度一致性不好，整屏不同角度的白平衡效果將是糟糕的。</p><div

style="text-indent:25px">一般金的導(dǎo)電率比較好，銀次之。在焊接工藝時，由于焊接實(shí)際上是形成合金的過程，這個合金本身就是良導(dǎo)體，所以焊接本身的可靠性是比較高的，除非是焊接不良。但是，連接器之間的連接，靠的是表面之間的接觸，所以容易導(dǎo)致接觸不良，更具體的原因分析如下。兩個金屬表面之間的接觸是否良好，主要取決于材料（不同金屬導(dǎo)電率不同)、接觸壓力、實(shí)際接觸面結(jié)。關(guān)于材料種類，上面已經(jīng)提到了，一般器件的鍍層材料，基本上都是由良導(dǎo)體做的，對接觸不良的影響不大。</p><p style="text-indent:25px">我們要為太陽能電池組件選擇一個zui佳傾角。關(guān)于太陽能電池組件zui佳傾角問題的探討，近年來在一些學(xué)術(shù)刊物上出現(xiàn)得不少。本次路燈使用地區(qū)為廣州地區(qū)，依據(jù)本次設(shè)計參考相關(guān)文獻(xiàn)中的資料[1]，選定太陽能電池組件支架傾角為160。2.3.2抗風(fēng)設(shè)計在太陽能路燈系統(tǒng)中，結(jié)構(gòu)上一個需要非常重視的問題就是抗風(fēng)設(shè)計。抗風(fēng)設(shè)計主要分為兩大塊，一為電池組件支架的抗風(fēng)設(shè)計，二為燈桿的抗風(fēng)設(shè)計。下面按以上兩塊分別做分析。(1)太陽能電池組件支架的抗風(fēng)設(shè)計依據(jù)電池組件廠家的技術(shù)參數(shù)資料，太陽能電池組件可以承受的迎風(fēng)壓強(qiáng)為2700Pa。LED亮度的衰減會造成顯示屏整屏亮度降低。</p><div

style="text-indent:25px">若抗風(fēng)系數(shù)選定為27m/s（相當(dāng)于十級臺風(fēng)），根據(jù)非粘性流體力學(xué)，電池組件承受的風(fēng)壓只有365Pa。所以，組件本身是完全可以承受27m/s的風(fēng)速而不至于損壞的。所以，設(shè)計中關(guān)鍵要考慮的是電池組件支架與燈桿的連接。在本套路燈系統(tǒng)的設(shè)計中電池組件支架與燈桿的連接設(shè)計使用螺栓桿固定連接。(2)路燈燈桿的抗風(fēng)設(shè)計路燈的參數(shù)如下:電池板傾角A
