Embodiment Construction
[0036] FIG. 1 is a block diagram of a preferred embodiment of the LED control device of the present invention. As shown in FIG. 1 , the LED control device 10 includes a sensing unit 11 , a control unit 12 and a driving unit 13 . The sensing unit 11 is used for detecting the light intensity of an LED (located in the driving unit 13 , not shown in FIG. 1 ), and outputting a corresponding sensing signal. In one embodiment, the sensing unit 11 uses a photodiode (not shown) to detect the light intensity of the LED.
[0037] The control unit 12 is coupled to the sensing unit 11 , and can judge whether the light intensity of the LED meets a set value according to the sensing signal output by the sensing unit 11 to generate a control signal and send it to the driving unit 13 . When the light intensity meets the set value, the control unit 12 keeps outputting the original control signal, so that the driving unit 13 maintains the light intensity that meets the set value. However, when...
