Driverless Ceramic AC 110V 220V COB
1. Uniformity of the luminous surface: stable performance, no dead lights, no light spots, no ghosting, no glare, no eye damage;
2. High luminous efficiency: The ceramic substrate has high reflection efficiency, and the luminous efficiency is 10% higher than that of Sharp's COB light source and 50% cheaper than Sharp's price;
3. High reliability: the ceramic substrate and the chip substrate are both AL2O3 materials, the expansion coefficient is similar, and the crystal is not caused to open due to temperature changes, resulting in attenuation and dead light, ensuring the stability of the chip;
4. Low thermal resistance: The thermal resistance is lower than 8 ° C / W, and the ceramic substrate is a high temperature sintered silver coating. The LED chip is directly packaged on the ceramic substrate, and the heat is directly transmitted on the ceramic substrate, and the heat dissipation is fast;
5. High insulation: high voltage resistance above 4000V, good safety, matching high voltage and low current power supply, can pass the safety certification of Europe and America;
6. Easy to install, direct installation and use, no need to consider other process design, saving a lot of labor costs.
