每個人都知道LED節能燈,那么知道為什么節能嗎?
       每個人都知道LED節能燈,那么知道為什么節能嗎?
       LED是有半導體材料所制成之發光元件,LED節能燈的發光原量是由元件具有的兩個電極端子,在端子間施加特定的電壓,通入小電流,經由電子電洞之結合可剩余能量以光形式激發釋出,這個即是LED節能燈發光原理。
       LED單管功率0.03~0.06瓦,采用直流驅動,單管驅動電壓1.5~3.5伏,電流15~20毫安,反應速度快,可在高頻操作。同樣照明效果的情況下,耗電量是白熾燈泡的**之一,熒光燈管的二分之一,一千小時僅耗幾度電(普通60w白熾燈十七小時耗1度電,普通10w節能燈一百小時耗1度電)。因此LED節能的的耗電量就相對的減少。
