摘要： A lighting apparatus includes a rectifier, a loading module, a constant current switch module and a current supplemental module. The rectifier is connected to an output of the AC power for receiving an AC signal to convert the AC signal to a positive wave signal. The loading module includes multiple loading units. The loading module is disposed on the output of the rectifier. The constant current switch module is connected to output of each loading unit and to control the working cycle of each loading unit so as to ensure a total passing current of the loading module is opposite in phase to the positive wave signal to keep output power constant. The current supplemental module supplies output current to the loading module when the positive wave signal is in sufficient to drive the loading module.

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.

摘要： A lighting apparatus includes a light source module, a light passing cover, a prism plate and a surface rim. The light source module includes a light source plate and multiple LED modules mounted on the light source plate. The light passing cover has a first side facing to the multiple LED modules for receiving a light from the multiple LED modules. The prism plate is disposed with more than 50 prism units for diffusing the light passing through the light passing cover from a second side of the light passing cover. The surface rim has a light opening for the light diffused by the prism units to escape from the lighting apparatus.

摘要： A lighting apparatus includes a first light source, a second light source and a driver. The first light source has multiple first LED modules. The second light source has multiple second LED modules. The driver controls the first light source and the second light source to generate an output light of a required mixed color temperature. The driver selects a first subset of the multiple first LED modules and a second subset of the multiple second LED modules to generate a first output light with a first color temperature. The driver selects a third subset of the multiple first LED modules and a fourth subset of the multiple second LED modules to generate a second output light with a second color temperature. The first subset is not equal to the third subset. The second subset is not equal to the fourth subset.

摘要： 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.

摘要： A light device holder includes a first paper wall, a second paper wall, a first lateral wall, a second lateral wall and a spacer plate. The light device holder is designed containing and enclosing multiple light bulbs. The second paper wall is opposite to the first paper wall. Two sides of the first paper wall and the second paper wall are respectively connected to edges of the first lateral wall and the second lateral wall forming a rectangular container space. The spacer plate has a first plate part and a second plate part. The first plate part engages an inner surface of the first paper wall. The second plate part is folded from the first plate part to extend as a tilt surface to divide the rectangular container space into a first space part and a second space part.
