LED手電(dian)筒的種類與特(te)點

1、LED超長使用壽命，一般可達到(dao)5萬(wan)小時以上比傳統(tong)鎢(wu)絲燈壽命高出5~10倍。

2、冷光，發熱度低，不會損(sun)壞(huai)燈座安全性高(gao)。

3、反應速度快，耐沖撞(zhuang)、體積小、易小型輕量化等。

4、省電(dian)、節(jie)能(neng)，新環保燈泡。

5、反(fan)應速度(du)快(kuai)只(zhi)要(yao)1us(微秒(miao))，不需暖燈可提高安全(quan)度(du)。

6、低壓驅動安全。

由于以上的(de)(de)諸多優點(dian)，LED已逐步應(ying)(ying)(ying)用(yong)(yong)(yong)(yong)于：背光，交通(tong)燈，城市亮(liang)化，汽(qi)車燈，通(tong)用(yong)(yong)(yong)(yong)照(zhao)明(ming)燈。在(zai)(zai)這里要介紹一下大功(gong)(gong)率(lv)LED在(zai)(zai)手電(dian)筒(tong)上的(de)(de)應(ying)(ying)(ying)用(yong)(yong)(yong)(yong)。近年來，隨著(zhu)高(gao)亮(liang)度LED的(de)(de)技(ji)術逐漸成熟，成本也不(bu)斷下降，各種(zhong)不(bu)同(tong)規格的(de)(de)高(gao)亮(liang)度LED也就較普(pu)遍地應(ying)(ying)(ying)用(yong)(yong)(yong)(yong)在(zai)(zai)新型(xing)的(de)(de)照(zhao)明(ming)設(she)備中。目(mu)(mu)前這種(zhong)高(gao)亮(liang)度的(de)(de)LED應(ying)(ying)(ying)用(yong)(yong)(yong)(yong)在(zai)(zai)手電(dian)筒(tong)里，可以說是最適合不(bu)過了，因為這種(zhong)高(gao)亮(liang)度LED的(de)(de)效率(lv)高(gao)、壽(shou)命長(chang)、發光的(de)(de)顏色純正(zheng)。目(mu)(mu)前還不(bu)能造出大功(gong)(gong)率(lv)的(de)(de)LED，但小(xiao)功(gong)(gong)率(lv)的(de)(de)LED很適合用(yong)(yong)(yong)(yong)在(zai)(zai)手電(dian)筒(tong)之類的(de)(de)小(xiao)型(xing)照(zhao)明(ming)裝置上。

LED手電(dian)筒是以LED發光二極管作為(wei)光源的(de)一種(zhong)成熟應用照明(ming)工具(ju)，它具(ju)有(you)省(sheng)電(dian)、耐(nai)用、亮(liang)度強等優點。

LED手電筒的類型

目前市場(chang)上各(ge)類照(zhao)明用手(shou)(shou)電(dian)(dian)筒(tong)，主要有塑料手(shou)(shou)電(dian)(dian)筒(tong)、LED手(shou)(shou)電(dian)(dian)筒(tong)、鐵手(shou)(shou)電(dian)(dian)筒(tong)、鋁(lv)合金手(shou)(shou)電(dian)(dian)筒(tong)、不銹鋼手(shou)(shou)電(dian)(dian)筒(tong)、手(shou)(shou)搖(yao)手(shou)(shou)電(dian)(dian)筒(tong)、環保手(shou)(shou)電(dian)(dian)筒(tong)、電(dian)(dian)蚊拍(pai)手(shou)(shou)電(dian)(dian)筒(tong)等許多種類。這(zhe)里我們重點了(le)解下(xia)LED手(shou)(shou)電(dian)(dian)筒(tong)的分類。

目前(qian)常見(jian)的(de)LED手電(dian)(dian)筒(tong)有小巧的(de)鑰匙扣型、多燈(deng)頭(tou)型、單(dan)燈(deng)頭(tou)大功率(lv)型等。從電(dian)(dian)源的(de)類型來(lai)看，有采用(yong)(yong)(yong)一(yi)(yi)只AA電(dian)(dian)池(chi)或(huo)一(yi)(yi)只AAA電(dian)(dian)池(chi)，有的(de)采用(yong)(yong)(yong)三只AAA電(dian)(dian)池(chi)，也有的(de)采用(yong)(yong)(yong)三個紐扣電(dian)(dian)池(chi)的(de)，還有采用(yong)(yong)(yong)手動(dong)發電(dian)(dian)的(de)等等。
