20100253235 | Non-flashing brightness adjusting device for non-resistive light-emitting load - A non-flashing brightness adjusting device for a non-resistive light-emitting load has a brightness adjuster and a conductive current sustainer. The brightness adjuster has an AC silicon-controlled rectifier (SCR) and an adjustable trigger unit. By adjusting the adjustable trigger unit and setting a trigger angle of the TRIAC, a total output current of the brightness adjuster is adjusted. The conductive current sustainer is connected to the output terminal of the brightness adjuster for a non-resistive light-emitting load to connect. When the trigger angle of the TRIAC is greater than 90 degrees, the conductive current sustainer keeps the current flowing through the anode and cathode of the TRIAC not lower than its threshold current to maintain the conduction of the TRIAC. Therefore, the non-resistive light-emitting load keeps receiving the required working power and does not flash. | 10-07-2010 |
