The first light source emits a first light with a first color temperature. The second light source emits a second light with a second color temperature. The third light source emits a third light with a third color temperature. The driver generates a first driving current to the first light source, generates a second driving current to the second light source, and generates a third driving current to the third light source.

Lighting apparatus

A lighting apparatus includes a light source plate, LED modules and a driver module. The light source plate includes a substrate layer, a wiring layer and a protection layer. The substrate layer is made of metal material. LED modules are disposed on a top side of the light source plate. The driver module is disposed on the top side of the light source plate. The LED modules and the driver module are electrically connected via the wiring layer. The driver module includes an AC-DC converter, a regulator, a controller, a current source and an oscillation wave removal circuit. The controller controls the current source to generate driving currents to the LED modules. The oscillation wave removal circuit is coupled to the AC-DC converter for suppressing a sudden abnormal peak voltage from the AC-DC converter.

A lighting apparatus includes a filter tuner, a bridge rectifier, multiple types of LED modules, a monitor circuit, and a current source. The filter tuner is connected to a manual switch and an external AC power. The filter tuner changes a conductive angle of the external AC power to an adjusted AC input. The bridge rectifier receives the adjusted AC input to generate a DC output. Multiple types of LED modules are disposed for emitting lights of multiple color temperatures. The monitor circuit monitors the conductive angle to generate a control signal. The current source, according to the control signal, generates multiple corresponding driving currents respectively supplied to the multiple types of LED modules to mix a desired color temperature. The desired color temperature is associated with the conductive angle according to a predetermined relation.

A lighting apparatus includes a bridge circuit, a current source, a first LED module, a second LED module and a switch. The bridge circuit is used for rectifying an input AC power to generate a DC power. The current source receives the DC power to generate a driving current. The first LED module emits a first light of a first color temperature. The second LED module emits a second light of a second color temperature. The switch is coupled to the current source to change at least a resistance parameter corresponding to a current ratio between the first LED module and the second LED module to generate a mixed light of a mixed color temperature.

A lighting apparatus includes a solar plate, a battery, a driver module, a light source, a lens tube, a main housing and a plugging bar. The solar plate converts a sunlight to an electricity. The battery stores the electricity. The driver module converts the electricity stored in the battery to a driving current. The solar plate is placed on a top side of the driver module and the light source is placed on a bottom side of the driver module. The lens tube has a top opening and a bottom opening. The top opening has a larger size than the bottom opening. The top opening is closer to the light source than the bottom opening. A light of the light source is emitted via a lateral lens surface of the lens tube between the top opening and the bottom opening.

A lighting apparatus includes a main module and an extended module. The main module includes a power circuit, a light source, a first network interface and a controller. The power circuit is controlled by the controller to generate a driving current supplied to the light source by converting an external power source. The extended module includes a function circuit and a second network interface. The function circuit communicates with the controller via the second network interface and the first network interface to add an extended function for the controller to enhance controlling of the light source. When the extended module is detachable from the main module, the main module is operated independently without the extended function.

A lighting apparatus includes a light source, a silicon controlled rectifier, a rectifier and a current source circuit. The light source has multiple LED modules with different light parameters. The silicon controlled rectifier filters a filtering ratio of an input AC power to a filtered AC power. The filtering ratio is associated with a control angle by supplying a control voltage to the silicon controlled rectifier. The maintainer circuit maintains a working current to the silicon controlled rectifier even when the control angle is large causing the volume of the filtered AC power less than a threshold. The current source circuit receives the DC power. The current source circuit has a wall switch input for connecting to a wall switch. An on-off input pattern of the wall switch is detected by the current source circuit for generating multiple corresponding driving currents.

A lighting apparatus includes a driver, a metal plate, a light source module and a conductor unit. The driver receives an alternating current power source and converts the alternating current power source to a driving current. The metal plate is electrically connected to a ground. The light source module has a substrate and multiple LED modules. The multiple LED modules are mounted on the substrate. The substrate is disposed upon the metal plate. The conductor unit has a first end connected to the substrate of the light source module and a second end connected to the metal plate for removing a parasitic capacitance between the substrate of the light source and the metal plate for preventing a noise occurred when the LED module is turned on and the metal plate is connected to the ground.
