We have now released our latest market research report,The World Market for COB LEDs in General Lighting, which covers the market for LED COBs and Multichip Array COBs. We forecast the overall market for these COBs will grow significantly to $4.35 billion in 2020 from $1.54 billion in 2014. In addition, the report indicates that the market will grow by 40% YoY in 2015. The long term growth is mainly due to the increased penetration of COB luminaires and lamps into some specific lighting applications, such as downlights and spotlights. With better light distribution and design flexibility, we expect a significant growth for COB, especially in directional lighting applications.
The benefits of COBs are better light distribution, design flexibility, and the fact that COBs are the wide-area light emitters, which make COBs ideal for light applications including downlights, spotlights, street lights, and high bays. However, heat management and government regulations are the main impediments to driving demand for COBs in certain applications. One such regulation that might drag the penetration rate is the “Dark-Sky Movement,” which is an initiative to reduce light pollution. This regulation seeks to reduce the glare coming out of outdoor street lights and other decorative lights in order to deal with light pollution and to cut down on energy usage.
The report also includes major COB suppliers in the world, such as Cree, Nichia, Citizen, Osram, and others. Obviously, Japanese LED packagers dominate the market. In addition, we have a discussion of different materials of COB substrates.
Everyone agrees that LED lighting mainly drives the growth of LEDs. We believe that COB is in the uptrend, and LED packagers must catch the growth of COB by application and by region to explore the market opportunities. Because the market for COBs is poised to see growth, the markets for some specific applications are expected to have 11%~28% CAGRs from 2015 to 2020. In the long term, COBs will eventually dominate the market in some lighting applications.
