2.設(shè)計(jì)散熱器用的一些參數(shù)：金屬的比熱，金屬的導(dǎo)熱系數(shù)，芯片熱阻、散熱器熱阻、周圍環(huán)境空氣熱阻等。 </p> <p> 3.確定采用散的類型，（自然對流散熱、強(qiáng)風(fēng)冷卻、熱管散熱，以及其它的散熱散熱方式。）從造價比較：自然對流散熱造價比較低，強(qiáng)風(fēng)冷卻中等，熱管散熱造價較高，噴氣致冷造價比較高。 </p> <p> 4.確定LED燈具許可的比較高工作溫度（環(huán)境溫度加燈具許可溫升）， </p> <p> 5.計(jì)算散熱器的體積、散熱面積。并確定散熱器的形狀。 </p> <p> 6.將散熱器與LED燈組合成完整燈具，并通電工作八小時以上，在室溫39℃--40℃的環(huán)境下檢查燈具的溫度，看是否滿足散熱要求，以檢驗(yàn)計(jì)算是否正確，如不滿足使用條件，鋁型材燈亮化照明，則要重新計(jì)算和調(diào)整參數(shù)。 </p> <p> 7.散熱器與燈罩的密封要做到防水、防塵，鋁型材燈亮化照明，燈罩與散熱器之間要墊抗老化的橡皮墊或硅橡膠墊，用不銹鋼螺栓緊固，做到密封防水，鋁型材燈亮化照明、防塵通過以上四點(diǎn)注意事項(xiàng)，再參照我國頒布的室外照明燈具技術(shù)規(guī)范，以及城市道路照明設(shè)計(jì)標(biāo)準(zhǔn)，這是戶外照明設(shè)計(jì)師在必備的**基本知識。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="鋁型材燈亮化照明"

1、防雷能力。眾所周知，戶外雷擊氣候?qū)﹄娫次：艽?，通常有直擊雷、傳?dǎo)雷、感應(yīng)雷等幾種類型，而感應(yīng)雷**為普遍，對電源破壞也比較大，往往產(chǎn)生4KV甚至更高電壓。好電源應(yīng)具備較好的防雷能力，并遵循國家相關(guān)設(shè)計(jì)標(biāo)準(zhǔn)(GB/T 17626.5，該標(biāo)準(zhǔn)等同IEC-61000-4-5，規(guī)定差?？箟?KV，共?？箟?KV)。 </p> <p> 2、抗高溫耐寒能力。有些地區(qū)外界氣溫可高達(dá)50℃，而比較低時又往往低至零下30℃，這就要求電源必須具備較寬范圍的工作環(huán)溫。 </p> <p> 3、防水能力。市面電源防雨和防水雖一字之差，但防護(hù)能力差別很大，防雨的防護(hù)等級只要求IP65，而防水的防護(hù)等級則要求IP67，意味著即使電源浸在水里，也可安全使用，可規(guī)避潮濕水氣、鹽霧等對電源內(nèi)部PCB線路及元器件的影響。 </p> <p> 除此之外，電源的過溫保護(hù)、過壓保護(hù)、欠壓保護(hù)、短路保護(hù)、甚至過功率保護(hù)等功能也必不可少。 </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="鋁型材燈亮化照明"

LED大功率投光燈這類產(chǎn)品的確在照明效果上能夠讓人眼前一亮，而且本身的特性和實(shí)用性也能夠滿足消費(fèi)者的需求。那么在平常不使用的情況下，到底應(yīng)該如何進(jìn)行產(chǎn)品的保養(yǎng)呢？ </p> <p> 首先保養(yǎng)的靠前步就是需要將LED大功率投光燈的電源關(guān)閉掉。這個是所有燈具進(jìn)行保養(yǎng)必須要做到的一步。因?yàn)檫@樣做能夠保證整個保養(yǎng)過程是安全的，而且也不會對產(chǎn)品的電路產(chǎn)生危害。所以關(guān)閉電源是必須要做的事情。其次在清潔的時候一定要用干燥的抹布來進(jìn)行擦拭。沾了水的抹布往往會對照明燈具產(chǎn)生一定的傷害，比如說水滴到燈具里面了，如果發(fā)生這樣的情況，那么對于這類產(chǎn)品來說是無可挽回的。所以在清潔的過程當(dāng)中，一定不要有任何的水漬。 </p> <p> 值得注意的是，清潔時同樣不要用化學(xué)物質(zhì)來進(jìn)行擦拭，比如說洗潔精等等，這些具有化學(xué)性質(zhì)的物質(zhì)往往會對LED大功率投光燈的表面有腐蝕的影響。 </p> <p> 所以保養(yǎng)的工作需要注意很多方面的問題，其實(shí)整個工作進(jìn)行下來并不是很難，對一些細(xì)節(jié)上進(jìn)行適當(dāng)?shù)奶幚硗軌蜃尡ｐB(yǎng)工作起到相應(yīng)的效果。 </p></p><br /><p>文章來源地址:
