Abstract: A constant current control circuit includes a current source output module and at least two output circuits. Each of the output circuits includes an automatic constant current regulating module, a power transistor drive and control module electrically coupled to automatic constant current regulating module, and a load module formed of one or more LED devices and electrically coupled to a power transistor drive and control module. The constant current control circuit in operation tracks changes in current of each output circuit and regulates the currents of all the output circuits accordingly.

Abstract: The invention provides a constant current control device and a television including the constant current control device. The constant current control device includes a constant current control module and a switched-mode power supply module used for providing a stable voltage for a load. The constant current control module includes a constant current source unit used for providing a reference current, a constant current control unit used for keeping a current flowing through the load constant as the reference current, and a feedback unit used for keeping the voltage of the constant current control unit constant. The present invention, with a simple circuit structure, implements the objective of precisely controlling a current passing through a load.
