燈具特點(diǎn) LED Lightings Features | 輸(shū)出功率恆定，無(wú)50Hz頻閃，有較強(qiáng)高頻電磁波輸(shū)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(shū)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。
Output power declines in constant voltage.Dimmable. 50 Hz frequency flash; no high-frequency electromagnetic wave.Power changing, environmental temperature and convection situation don’t effect lightings temperature.
