| 20090167478 | DEVICE FOR IMPROVING EDDY CURRENT LOSS OF TRANSFORMER AND CONTROLLING METHOD THEREOF - The configurations of a device diminishing the eddy current loss for a transformer having a gap are provided in the present invention. The proposed device includes a conductive case having an eddy current diminishing opening opposite to the air-gap and an insulator disposed between the eddy current diminishing opening and the transformer. | 07-02-2009 |
| 20090261752 | BALLAST - A ballast comprising a first input terminal, a second input terminal, a switch circuit, and a plurality of lamp sets is provided. The switch circuit comprises a first switch and a second switch connected with the first one. The switches are connected with the first and second input terminals respectively. The lamp sets are connected in parallel with each other and have an arrangement sequence. Each of the lamp sets is coupled to the first and second switches and comprises a first lamp having a first filament. The filaments are connected in series according to the arrangement order so that at least one junction is formed in the at least one connection point. The first one of the first filaments is coupled to the first switch. The last one of the first filaments is coupled to the second switch. Thereby, the ballast can be implemented by less internal connection terminals and leads. | 10-22-2009 |
| 20120013268 | LIGHTING DEVICES - A lighting device is provided, having at least one light emitting diode module, a power factor correction circuit, a non-regulated isolation DC to DC converter and at least one regulated non-isolation DC to DC converter. The power factor correction circuit performs a power factor correction on an AC power source and outputs a corrected DC voltage. The non-regulated isolation DC to DC converter generates an output voltage in a predetermined voltage range according to the corrected DC voltage, wherein the non-regulated isolation DC to DC converter is an open-loop controlled buck DC to DC converter. The regulated non-isolation DC to DC converter generates a fixed current or a fixed voltage according to the output voltage output from the non-regulated isolation DC to DC converter, thereby driving the light emitting diode module. | 01-19-2012 |
