Constant Current Control Device and Television Having the Same

A television, comprising a constant current control device, wherein the constant current control device, comprising:

• a constant current control module;
• a switched-mode power supply module, used for providing a stable voltage for a load;
• wherein the constant current control module comprises:
• 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,
• wherein an output terminal of the switched-mode power supply module is electrically connected to an input terminal of the load;
• an output terminal of the constant current source unit is electrically connected to a first input terminal of the constant current control unit;
• an output terminal of the load is electrically connected to a second input terminal of the constant current control unit;
• an output terminal of the feedback unit is electrically connected to a control terminal of the constant current control unit;
• both of a first input terminal of the feedback unit and a first input terminal of the switched-mode power supply module are electrically connected to a first output terminal of the constant current control unit;
• and
• a second input terminal of the feedback unit and a second input terminal of the switched-mode power supply module are both connected to a second output terminal of the constant current control unit.
