摘要： A detect method is provided for performing step dimming selection in an electronic ballast including an End of Lamp Life detect circuit and a half-bridge inverter, the End of Lamp Life detect circuit being connected to an input terminal of the control circuit, wherein each time when the power switch is turned on, it is judged whether the electronic ballast should enter the dimming mode or not by detecting the voltage at the input terminal of the control circuit before the half-bridge inverter starts operating.

摘要翻译： 提供了一种检测方法，用于在包括灯寿命检测电路和半桥逆变器的电子镇流器中执行步进调光选择，灯寿命检测电路连接到控制电路的输入端，其中每次 当电源开关打开时，通过在半桥逆变器开始运行之前检测控制电路输入端的电压，判断电子镇流器是否进入调光模式。
