synthetic efficiency, ie, when the correlated color temperature is 3000 K to 160 lm / W (cx 0.45 / cy 0.44). If applied this technology to 2 mm chip, operating current under the same conditions, the light efficiency can be further increased by 10% to 15%, that is, pure warm white LED Efficiency is expected to reach 180 lm / W, while achieving a good color.
The key light efficiency can be improved is to film and UX: 3 chip technology in the conversion of new technology and new technology combi
