1919 Bi-color COB Led Chip Introductions
COB LEDs are basically multiple LED chips packaged directly to a substrate by light to form a single LED module. The multiple chips take up less space and the highest potential of the LED chips can be obtained. When the COB LED package is energized, it appears more like a lighting panel.
With the advanced knowledge and packaging technology for years, COB LED has excellent reliability and high‑flux, multi‑die chips in a smaller, easy‑to‑use platform. With LED lighting‑class reliability, LED array’s small, uniform emitting surface enables both directional and non‑directional lighting with new levels of flux and efficacy. COB LED series covers a wide range of luminous flux from 3W to 300W. The element arrangement of LED package is capable of utilizing light more effectively and higher performance. Due to success of reducing the thermal resistance significantly,COB LED creates more options to match luminaire’s products design with perfect performance, cost effective, high lumen density, etc
