A LED light apparatus includes an electrical connector device for electrically connecting a light source board and a driver board. The electrical connector device comprising an input terminal and an output terminal, one end of input terminal is fixed on the driver board of the LED light and electrically connected to the driver board. The output terminal includes a conductive terminal, an elastic clipping portion, and a resistance portion, the conductive terminal includes a conductive pin, the conductive pin is fixed on the light source board and electrically connected to the light source board, the resistance portion are placed on the conductive terminal, and when assembled, the other end of the input terminal elastically touches one end of the elastic resistance portion and the resistance portion touches the other end of the resistance portion. The electrical connector of LED light owns the advantages of simple structure and high reliability.
