    • A method for using an electronic ballast circuit configured to operate a high intensity discharge (HID) lamp. Multiple light emitting diodes (LEDs) are attached to the current output of the electronic ballast circuit, and current is driven from the current output to light said LEDs. Optionally, prior to driving current through the LEDs, the impedance of the current output is sensed; and the current is driven through the LEDs to light the LEDs upon detection of an impedance significantly lower than an impedance characteristic of the HID lamp. Ignition appropriate to ignite the high intensity discharge is not performed when LEDS are attached to the current output. Alternatively, a signal is provided to disconnect the LEDs during a high voltage output for ignition of the high intensity discharge (HID) lamp.
    • 一种使用构造成操作高强度放电(HID)灯的电子镇流器电路的方法。 多个发光二极管(LED)连接到电子镇流器电路的电流输出,并且电流从电流输出驱动以点亮所述LED。 可选地,在驱动通过LED的电流之前,感测电流输出的阻抗; 并且当检测到比HID灯的阻抗特性明显低的阻抗时,电流被驱动通过LED来点亮LED。 当LEDS连接到电流输出时,不执行适合点燃高强度放电的点火。 或者,提供信号以在用于点亮高强度放电(HID)灯的高压输出期间断开LED。
