Recently, the QILSTE R&D team successfully developed a COB integrated light source module with high color rendering index and high luminous efficiency, and realized mass production. High luminous efficiency and high color rendering are key technologies in the field of LED semiconductor lighting. High luminous efficiency means more energy saving than traditional light sources, and high color rendering presents more realistic colors. The COB integrated packaging form makes the device have good consistency, almost no color difference, simple structure, and easy to use.

       This COB integrated module adopts high-temperature co-fired ceramic substrate with high thermal conductivity and copper substrate with high thermal conductivity with independent intellectual property rights. Combined with chip-on-board technology, the luminous efficiency reaches 125lm/ in the neutral white area. W above, while the color rendering index reaches above 90. This series of products will be widely used in lighting products for indoor lighting, and become an ideal light source for lamps such as bulb lamps, downlights, and spotlights.
