LED灯由于响应速度快,且也不具备传统灯具的热惯性和余辉效应,因此深受电流波动的影响。电流的波动直接影响光通量的输出,而光源闪烁就是光通量变化的外在体现,__也就是所说的频闪问题__。

关于LED频闪,最简单的定义就是指开关周期内光的不断波动。例如在美国,电流是通过频率为60Hz的交流电传送的,灯具澳门足彩的供电电压在开关周期内以正弦波的形式在波峰到波谷之间来回波动。因此,可能产生2倍于供电频率的频闪,也就是120Hz。如果没有合适的电子电路,比如镇流器、驱动或电源,LED光源就会产生频闪。

某些程度的频闪不会引起注意,也不存在生理上的不适,但有些频闪却会引起严重后果。在一些工厂中,已经把照明灯具澳门足彩全部换成低频闪方案,从而提高产线人员的工作效率;市面上一些家用台灯也在推广低频闪的产品,倡导对于保护视力的重要性;另外在一些博物馆或是展览会场中,也需要保安监控下无水波纹的照明产品,这样才能时刻保证严密、高安全的监控效果。
