Description

technical field [0001] The invention relates to a ceramic, in particular to a ceramic for a ceramic LED lamp. Background technique [0002] At present, the basic structure of LED (light-emitting diode) is a piece of electroluminescent semiconductor material, which is placed on a shelf with leads, and then sealed with epoxy resin around it to protect the inner core wire. LED light source has the advantages of using low-voltage power supply, less energy consumption, strong applicability, high stability, short response time, no pollution to the environment, multi-color light, etc. Although the price is more expensive than existing lighting equipment, it will inevitably replace Existing lighting fixtures. At present, the heat dissipation of LED lamps is a major problem in this technical field. In order to solve the heat dissipation problem, ceramic materials are gradually appearing to replace the glass materials of existing LED lamps, so as to better realize heat dissipation. ...
