摘要:
A lighting apparatus includes an AC-DC converter, multiple LED modules, a mixing unit, a controller and a power supply. The AC-DC converter converts an AC power source to a DC output. The multiple LED modules have different light parameters. The mixing unit is coupled to the multiple LED modules for mixing a mixed light parameter according to a control signal by supplying driving currents to the multiple LED modules corresponding to the mixed light parameter. The mixing unit receives the DC output to generate the driving currents. The controller generates the control signal. The power supply receives the DC output to generate a working power to the controller. When the AC-DC converter is turned off, a releasing power of the mixing unit is moved to the power supply to align turn-off timings of the power supply and the mixing unit.
