In summary, Chip on Boards are being used by customers from different markets. Some customers will like Philips’ CoB due to their small LES (so they can build with smaller reflectors). Other customers will like Philips’ MCPCB solution, which is more robust in the manufacturing process compared to ceramic solutions used by a lot of competitor CoB makers. Lastly, all of the CoBs are tested and guaranteed at 85 degrees. This means that there is no lumen degradation or color shift compared to the datasheet when designers use them in an application.
