Abstract
The present application discloses a circuit for driving a light emitting diode light source assembly having a plurality of light emitting diode groups, each group having at least one light emitting diode. The circuit includes a processor configured to determine a set brightness level, calculate a number of light emitting diode groups required to be on to achieve the set brightness level, and select the number of light emitting diode groups to be turned on at allocated positions in the light emitting diode light source assembly; and a driving sub-circuit configured to turn on the number of light emitting diode groups at the allocated positions. The number of light emitting diode groups is a positive integer N, N is less than a total number of the plurality of light emitting diode groups.
