Basic Concepts of Ceramic High Power LED

Ceramic high power LED refers to a type of high-power light-emitting diode that uses ceramic materials as the substrate and encapsulation material. Compared with traditional LED, ceramic high power LED has the following advantages: 1. Excellent thermal conductivity: Ceramic materials have good thermal conductivity, which can effectively dissipate heat generated by the LED chip, thereby improving the stability and reliability of the product. 2. High thermal expansion coefficient: The thermal expansion coefficient of ceramic materials is close to that of silicon, which can reduce the stress generated during the thermal expansion and contraction of the LED, thereby improving the product's lifespan. 3. Good chemical stability: Ceramic materials have good resistance to high temperature and corrosion, which can ensure the stable performance of the product in various environments. 4. High mechanical strength: Ceramic materials have high mechanical strength, which can effectively protect the LED chip and improve the product's durability.
