ILLUMINATION LAMP

摘要

An illumination lamp includes a lamp base, a lampshade, and electrical contacts. The lamp base is integrally formed of ceramics and has a control circuit and at least one LED element laid on its surface. The lampshade covers each LED element on the lamp base surface. The electrical contacts extend respectively and integrally from two ends of the lamp base. The control circuit is formed on the lamp base surface by high-temperature sintered silver chemically bonded to the ceramics and covers an external portion of each electrical contact such that the electrical contacts are in electrical conduction with the control circuit and the at least one LED element. Heat generated by the at least one LED element can be absorbed by the ceramic lamp base through the silver and dissipate rapidly. The illumination lamp features a simple structure with minimal components, a simplified manufacturing process, and low production costs.

主权项

1. An illumination lamp, comprising:
a lamp base integrally formed of a ceramic material, the lamp base having a surface laid with a control circuit and at least one light-emitting diode (LED) element; a lampshade covering each said LED element on the surface of the lamp base; and electrical contacts extending respectively and integrally from two ends of the lamp base, each said electrical contact having a front end formed as a halved cone; wherein the control circuit laid on the surface of the lamp base is formed on the surface of the lamp base by sintering silver at a high temperature and thereby chemically bonding the silver to the ceramic material, and the control circuit also covers an external portion of the electrical contact at each of the two ends of the lamp base such that the electrical contacts are in electrical conduction with the control circuit and the at least one LED element on the surface of the lamp base.
