    • A closed-loop LED drive circuit includes at least one LED, a voltage source, and a voltage regulator connected to the voltage source to provide a regulated voltage output. A one-time-programmable voltage source is connected to an output of the voltage regulator and a current controlled drive circuit is connected to the one-time-programmable voltage source for providing a drive current to the at least one LED in response to an output from the one-time-programmable voltage source. An end of line tester monitors the light intensity of the LED device and provides a signal indicative thereof to said one-time-programmable voltage source. The one-time-programmable voltage source stores the light intensity value and uses the light intensity value to control its output voltage to the current control drive circuit.
    • 闭环LED驱动电路包括至少一个LED,电压源和连接到电压源的电压调节器,以提供稳定的电压输出。 一次性可编程电压源连接到电压调节器的输出,并且电流控制驱动电路连接到一次可编程电压源,用于响应于输出向驱动电流提供至少一个LED 从一次性可编程电压源。 线路终端测试器监测LED装置的光强度,并向其指示一个信号给一次性可编程电压源。 一次可编程电压源存储光强值,并使用光强度值来控制其对电流控制驱动电路的输出电压。
