Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a ceramic material for LED lamps and a preparation method thereof. Background technique [0002] LED lights are more and more widely used in daily life due to their advantages of energy saving, environmental protection and long life. The basic structure of LED (light emitting diode) is a piece of electroluminescent semiconductor material placed on a shelf with leads. Then the surrounding is sealed with epoxy resin to protect the inner core wire. LED light source has the advantages of low-voltage power supply, low 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. Conventional LED light bulbs have poor heat dissipation, so that the life of LED light bulbs is sho...
