According to a latest market research report “The World Market for COB LEDs in General Lighting”, the whole COB LED market (LED COBs and Multichip Array COBs) to increase to US$4.4 billion in 2020 from US$1.5 billion in 2014, and the market will experience a very respectable 40% growth from 2014~2015.
The long-term growth is mainly due to the increased penetration of COBs into directional and high lumen applications. The research report notes that COBs have a better light distribution and design flexibility than other package types, which makes them more adapted to applications where you need to direct light, need a large quantity of usable lumens, or both.
For a few years now, there have been many proponents that claimed mid-power packaged LEDs were going to supplant all other LEDs in lighting applications. The train of thought was that since mid-power LEDs are cheaper, companies will just pack luminaires with more of these LEDs to get the desired lumen output. Strategies Unlimited has determined that this trend is shifting as it is much easier to design certain luminaires with higher power LEDs and as COB packages are coming down in price.
