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

Q2: Can I get some samples for tests?
A2: Yes, we can offer free samples, so you can have an intuitive
understanding about our LED quality and performance. But our
clients should pay for the shipping freight themselves.
Q3: What about the lead time?
A3: Generally, it will take 3-5 working days for sample and 7-25
working days for mass order.
Q4: Do you accept customized products?
A4: Yes, we can offer OEM and ODM service as per your request.
Please kindly leave us messages about your requirements, our sales
engineer will check the details as soon as possible.
Q5: How many years of warranty of products you offer? And how do
you deal with the LED working issues?
A5: We offer 3-year warranty by default, and longer warranty can be
negotiated. If there is any problem with the product during the
warranty, please feel free to contact us.
