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.

Abstract: The present invention relates to an improved automotive lamp structure, in which an automotive lamp includes a base, a first lamp holder, a second lamp holder and two light-emitting elements. Support portions are respectively located on corresponding surfaces of the first lamp holder and the second lamp holder, and the support portions enable the lamp holders to respectively rotate and be held open. Moreover, the light-emitting elements are respectively located in the first lamp holder and the second lamp holder. Accordingly, when installing the automotive lamp, each of the light-emitting elements assumes an open state by means of the support portions, which further results in providing the light-emitting elements with a larger scattering angle when emitting light, thereby enabling the automotive lamp to produce a more uniform light beam, and Improving the problems of automobile headlamps of the prior art producing a nonuniform light beam.

Abstract: An electroluminescent dashboard control circuit for automobile in which a voltage comparator is used to control the operation of different colors of electroluminescent lamps subject to the voltage level of inputted voice signal received from a microphone, and a switch is used to select full-light or auto operation mode.
