Abstract
A carry-signal controlled LED light with low power consumption includes at least one LED and a drive unit. The drive unit is coupled to the at least one LED, and receives a carry light signal to control the at least one LED. The drive unit includes a light control unit. The light control unit drives the at least one LED according to a light command content of the carry light signal. When a voltage of the carry light signal is less than a low-level voltage, the light control unit enters an eco mode, and the light control unit detects and identifies signals within a time interval. After the time interval, the light control unit enters a sleep mode.
