A light-emitting device is disclosed, in which a body and a heat-dissipating base disposed at a side of the body are provided. The heat-dissipating base has light-emitting elements located at a side of the body for emitting light, a printed circuit board for receiving the light-emitting elements and power lines through the heat-dissipating base and electrically connected to the printed circuit board, allowing heat-and-electricity separation, thereby improving reliability.
