发光二极管用驱动电路以及LED光源
摘要：
提供一种即使在提供了低于规定值的输入电压的情况下也能够可靠地熄灭LED的发光二极管用驱动电路以及LED光源。一种用于将LED(2)进行点亮的发光二极管用驱动电路(1)，具备：逆变器(20)，其输出用于驱动LED(2)的电力；以及逆变器控制电路(30)，其用于控制逆变器(20)的动作，其中，逆变器控制电路(30)在输入到该逆变器控制电路(30)的直流电压小于规定值的情况下使逆变器(20)的动作停止。
摘要（英）：

Provided are a light-emitting diode drive circuit and a LED light source, wherein an LED can be turned off with reliability, even when an input voltage lower than a prescribed value is supplied thereto. The light-emitting diode drive circuit (1) is for turning on an LED (2), and is provided with an inverter (20) for outputting power for driving the LED (2), and an inverter control circuit (30) for controlling the operation of the inverter (20). The inverter control circuit (30) stops the operation of the inverter (20), when DC voltage to be applied to the inverter control circuit (30) is less than a prescribed value.
