燈具特點(diǎn)

LED Lightings Features

???????????輸出功率恒定，無(wú)50Hz頻閃，有較強(qiáng)高頻電磁波輸出。燈具溫度受環(huán)境溫度，對(duì)流情況變化等影響較大。使用環(huán)境要求較高。

Constant output power; no?50?Hz frequency flash;?strong high-frequency electromagnetic wave.?Temperaturechanges with?environment. Convection situation?can be?greatly influenced.Requiring high?environmental?standards.

在額定電壓之下，輸出功率隨之下降，可調(diào)光。有50Hz頻閃，無(wú)高頻電磁波。燈具溫度不受電壓波動(dòng)，環(huán)境溫度，對(duì)流情況變化等影響。
