    • An electronic ballast is capable of realizing high frequency lighting of a discharge lamp and switching between at least two lighting modes with different light outputs. The ballast includes a preheating circuit having a winding component connected in parallel with a main resonant circuit with a lamp current flowing therein for the discharge lamp. A constant preheating current for the lamp filaments is supplied from a secondary winding of the winding component during lighting of the discharge lamp and a path of a current flowing on a primary winding side of the winding component is switched by a switch according to the lighting mode.
    • 电子镇流器能够实现放电灯的高频照明,并在不同光输出的至少两个照明模式之间切换。 镇流器包括预热电路,其具有与主谐振电路并联连接的绕组元件,其中流过其中的灯电流用于放电灯。 在放电灯点亮期间,灯丝的恒定预热电流从绕组部件的次级绕组提供,并且通过根据照明模式的开关切换在绕组部件的初级绕组侧流动的电流的路径 。
