A lighting apparatus includes a first LED module, a second LED module, a wireless module and a power module. The first LED module has a first light parameter. The second LED module has a second light parameter. The first light parameter is different from the second light parameter. The wireless module receives an external command and converts the external command to a driving control signal. The power module converts an AC power source to a first DC power and a second DC power. The first DC power has a first driving current and a second driving current respectively supplied to the first LED module and the second LED module. The power module adjusts a power ratio between the first driving current and the second driving current according to the driving control signal.

Lighting apparatus

A lighting apparatus includes a control circuit, a light source, a reset sensor and a reset circuit. The control circuit operates according to a default setting when the control circuit is started. The light source is controlled by the control circuit. The reset sensor detects a status variation. The status variation is caused by an external device outside the lighting apparatus. The reset circuit is coupled to the reset sensor for generating a reset signal to the control circuit to reset the control circuit when the status variation satisfies a predetermined triggering condition.

A lighting apparatus includes a light source, a bridge circuit, a voltage node, a filter circuit, a dimmer check circuit and a control circuit. The light source includes a LED module. The bridge circuit generates a DC power at a voltage node by converting an AC power. The filter circuit is connected to the voltage node for converting the DC power to a driving current to the LED module. The dimmer check circuit is coupled to the voltage node for generating a dimmer check signal by detecting whether a wall dimmer is electrically coupled to the lighting apparatus. The control circuit adjusts a setting of the filter circuit according to the dimmer check signal.

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.
