Embodiment Construction
[0045] figure 1 A block diagram showing a system architecture of an active current driver for a semiconductor light emitting device according to a preferred embodiment of the present invention. In this embodiment, a light emitting diode is used as a semiconductor light emitting element, however other light emitting elements are also applicable. The LED active current driver according to this embodiment can be used to drive the LED array module 200 , and the LED active current driver at least includes the LED active current regulation module 100 , the timing control module 300 , and the DC power supply module 400 . Wherein, the LED active current regulation module 100 may at least include three parts: a current regulation unit 110 , a feedback unit 120 and a compensation unit 130 .
[0046] As shown in the figure, the DC power supply module 400 is electrically connected to the LED array module 200 , the LED array module 200 is connected to the current regulation unit 110 , and...
