您好，您说的LED灯镇流器实际是LED灯的驱动电源，有输入端input和输出端output，input端是接入市电，output输出端是接到灯管上，如下图。一般只有外置电源的LED灯才会有这个驱动电源，如果是内置电源的LED灯，这个驱动电源内置在LED里面，驱动的OUTPUT接线到LED灯板上，驱动的INPUT是直接接线到LED灯的通电...
led驱动是input（输入）连电源，output（输出）是LED驱动器的输出。

5)下拉输入模式(Input Pull-down)如图 8.1.1 中②所示,Vss经过开关、下拉电阻,连接外部I/O引脚。当开关闭合,外部I/O无输入信号时,默认输入低电平。 6)浮空输入模式(Floating Input)如图 8.1.1 中②所示,两个上/下拉电阻开关均断开,既无上拉也无下拉,I/O引脚直接连接TTL肖特基触发器,此时I/O引脚浮空,读取...
EE =(Output or emitted power)/(Input or emitted power) = QE×SE 此为荧光材料进行光转换所释放出光能(或功率)与其所吸收光能(或功率)的比值。光散射转换效率(Scattering Efficiency)乃是荧光粉应用于LED当中,由于与封装材料之折射系数的不同,而产生光散射损失后所呈现的能量转换效率,另因在光转换的过程中,...
The output current should not exceed the rated cur¬rent of the LEDs used. The LED current thermal de-rating should be considered to protect the LEDs. The maximum voltage of an LED string the demo board can drive is limited by the duty cycle and the input voltage of the LT3496. The ...
