概述:20W吸頂式30W支架式40W吊頂式50W壁式防爆燈

LED防爆燈具的其中一個非常重要的防爆原理就是限制與爆炸性氣體、爆炸性粉塵接觸的外殼表面、零部件表面或電子元器件表面的溫度以及限制電氣接觸表面溫度低于其小點燃溫度或引燃溫度。

 

雅明電氣每日解答:

1、 什么是LED光衰

LED 產(chǎn)品的光衰就是光在傳輸中的訊號減弱,而現(xiàn)階段全球 LED 大廠們做出的

LED 產(chǎn)品光衰程度都不同,大功率 LED 同樣存在光衰,這和溫度有直接的關(guān)係,主要

是由LED光源、螢光粉和封裝技術(shù)決定的。目前,市場上的白光 LED 其光衰可能是向民用

照明進(jìn)軍的首要問題之一。

2、 影響LED光衰的兩大因素

1) LED 品質(zhì)問題

采用的 LED LED光源體質(zhì)不好,亮度衰減較快。

生產(chǎn)工藝存在缺陷,LED LED光源散熱不能良好的從 PIN 腳導(dǎo)出,導(dǎo)致 LED LED光源溫度過

使LED光源衰減加劇。

2) 使用條件問題

 LED 為恒流驅(qū)動,有部分 LED 采用電壓驅(qū)動原因使 LED 衰減過來。

驅(qū)動電流大于額定驅(qū)動條件。其實導(dǎo)致 LED 產(chǎn)品光衰的原因很多,關(guān)鍵的還是熱

的問題,盡管很多廠商在次級產(chǎn)品不特別注重散熱的問題,但這些次級 LED 產(chǎn)品長期

使用下,光衰程度會比有注重散熱的 LED 產(chǎn)品要。LED LED光源本身的熱阻、銀膠的影

響、基板的散熱果,以及膠體和金線方面也都與光衰有關(guān)系。

技術(shù)優(yōu)勢:

由于LED屬于固態(tài)冷光源,具有電光轉(zhuǎn)換率、發(fā)熱量小、耗電量小、工作電壓屬安全低電壓、使用壽命長等優(yōu)點,因此大功率白光LED是防爆燈具,特別是可攜式防爆燈具的一種非常理想的電光源。

LED防爆燈,路密封技術(shù);更符合防爆新技術(shù)。屬于一種特種行業(yè)中用電氣設(shè)備,主要解決照明問題,它包括燈殼、設(shè)置在燈殼前端的燈罩、設(shè)置于燈殼內(nèi)部的發(fā)光體及電池、設(shè)置于燈殼表面的開關(guān),其特征在于:
