Abstract

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.

Claims

1. A license plate lamp which is installed in a license plate device having plural locking elements, comprising:

a heat dissipation device, peripheries of which are extended with plural tenons;

a circuit board, which is electrically connected with plural light emitting elements and peripheries of which are formed with fastening parts at location corresponding to the tenons, with locations on the circuit board, departing from the light emitting elements, being provided with fastening elements corresponding to fastener holders; and

a shade, two ends of which are extended respectively with fixing elements to lock the circuit board.

2. The license plate lamp according to claim 1, further comprising a fastening spring leaf which is provided at a side of the shade and is abutted and positioned with the license plate device.

3. The license plate lamp according to claim 1, wherein the shade is further transparent or semi-transparent.

4. The license plate lamp according to claim 1, wherein the circuit board is electrically connected with a power source having a positive electrode and a negative electrode.

5. The license plate lamp according to claim 1, wherein the light emitting element is a light emitting diode.
