    • An LED light source module and a constant-current unit structure for use therewith are provided. The LED light source module includes a constant-current unit and an LED set. The constant-current unit includes a voltage stabilizing unit and a resistor. The resistor is parallel-connected between two output ends of the voltage stabilizing unit. An input end of the constant-current unit receives DC voltage, and one of the output ends of the constant-current unit outputs constant current. The LED set is electrically connected to the output end of the constant-current unit to receive constant current therefrom so as for the LED set to be powered-on. Regardless of fluctuation in the DC voltage received, the constant-current unit outputs stable constant current, and the LED set emits light steadily, thereby protecting the LED set against overcurrent-induced damage.

    • A light source device with an LED module includes a load module. The load module includes a voltage-regulating unit and a constant current controlling unit parallel-connected between a first output end and a second output end of the voltage-regulating unit. An input end of the voltage-regulating unit is connected to a positive end of a voltage source. The voltage-regulating unit generates a stable voltage difference of less than 1.6V between the first and second output ends. The LED module receives a residual voltage equal to the result of subtracting from the output voltage of the voltage source the voltage difference consumed by the load module. The amount by which the residual voltage exceeds the operating voltage required for the entire LED string never exceeds safe voltage values. Even if a voltage source changes, the voltage-regulating unit can still generate a stable voltage difference and a stable current.
    • 具有LED模块的光源装置包括负载模块。 负载模块包括电压调节单元和并联在电压调节单元的第一输出端和第二输出端之间的恒流控制单元。 电压调节单元的输入端连接到电压源的正端。 电压调节单元在第一和第二输出端之间产生小于1.6V的稳定电压差。 LED模块接收等于从电压源的输出电压减去由负载模块消耗的电压差的结果的残余电压。 剩余电压超过整个LED串所需的工作电压的量不会超过安全电压值。 即使电压源发生变化,电压调节单元仍能产生稳定的电压差和稳定的电流。
