    摘要: The LED lighting device includes a lighting circuit unit, a current detecting unit, a voltage detecting unit, and a control unit. The lighting circuit unit is adapted in use to be connected to a lamp socket to be connected to a LED lamp, and is configured to provide an output voltage in the form of a DC voltage to the lamp socket in a manner to turn on the LED lamp. The current detecting unit is configured to detect an output current which is caused by the output voltage and is supplied from said lighting circuit unit to said lamp socket. The voltage detecting unit is configured to detect the output voltage of said lighting circuit unit. The control unit configured to control the lighting circuit unit. The control unit is configured to perform constant-current control of control the lighting circuit unit in a manner to regulate the output voltage such that the output current is identical to a target value while keeping the output voltage not higher than a maximum-load voltage, when the output current detected by the current detecting unit is not less than a predetermined threshold value, and is configured to perform no-load control of controlling the lighting circuit unit in a manner to regulate the output voltage such that the output voltage is kept identical to a no-load voltage higher than the maximum-load voltage, when the output current detected by the current detecting unit is less than the predetermined threshold value.
