A license plate lamp is installed in a license plate device to illuminate a car-use license plate and is assembled by a heat dissipation device, a circuit board and a shade. The circuit board is electrically connected with light emitting elements and is locked with the circuit board. As two ends of the shade are extended respectively with locking elements, the shade can be locked with the circuit board to form the license plate lamp. Furthermore, because having a fastening spring leaf, the shade can be first positioned in the license plate device, and then the entire license plate lamp is fixed and locked with the license plate device by fastening elements on the circuit board. Therefore, a life time of usage of the license plate lamp can be extended by the heat dissipation device and the license plate device can be prevented from melting down by high temperature.
