发光二极管驱动系统及其烧录方法
摘要：
本发明公开了一种发光二极管驱动系统及其烧录方法，发光二极管驱动系统包含红外线烧录装置及发光二极管驱动装置。发光二极管驱动装置包含红外线接收单元、信号转换单元、储存单元、脉波宽度调变单元及二极管驱动单元。红外线接收单元接收红外线烧录装置传送的烧录信号。信号转换单元转换烧录信号为电流控制指令并传送至储存单元，并依据储存单元中的电流控制指令产生电流控制信号。脉波宽度调变单元依据电流控制信号产生脉波宽度调变输出电流控制信号。二极管驱动单元以脉波宽度调变输出电流控制信号驱动发光二极管。本发明省去了以电阻设定输出电流的时间，一次烧录多台装置并避免生产线人员的错误。
摘要（英）：

A light emitting diode driving system includes an infrared ray burning device and a light emitting diode driving device. The light emitting diode driving device includes an infrared ray receiving unit, a signal transforming unit, a storage unit, a pulse width modulating unit and a diode driving unit. The infrared ray receiving unit receives a burning signal transmitted by the infrared ray burning device; the signal transforming unit transforms the burning signal into a current control command and transmits it to the storage unit. The signal transforming unit generates a current control signal in accordance with the current control command in the storage unit. The pulse width modulating unit generates a pulse width modulation output current control signal according to the current control signal. The diode driving unit drives the light emitting diode by the pulse width modulation output current control signal.
