Microcontroller based ignition in high frequency ceramic metal halide lamps
Abstract:
A high frequency ballast for a metal halide lamp comprises a controller, a switch, and an oscillator. The controller selectively enables and disables the oscillator via the switch to ignite the lamp. The switch selectively tunes and detunes an inductor of the oscillator by altering an inductance of the inductor. When the inductor is tuned, the oscillator oscillates and provides power to the lamp. When the inductor is detuned, the oscillator does not oscillate and does not provide power to the lamp.
Abstract(Chinese):

用于金属卤化物灯的高频镇流器包括控制器，开关和振荡器。 控制器通过开关选择性地启用和禁用振荡器以点燃灯。 该开关通过改变电感器的电感来选择性地调谐和去调谐振荡器的电感器。 当电感调谐时，振荡器振荡并向灯提供电源。 当电感失谐时，振荡器不会振荡，也不向灯提供电源。
