According to the latest data, the market size of COB for lighting (including ceramic packaging/EMC packaging COB products) in 2016 reached US$580 million. It is estimated that the size of this market will exceed 700 million US dollars in 2021, and the compound growth rate between 2016 and 2021 is about 4%. COB products are mainly used in the commercial lighting market. With the improvement of technology, the performance of high-power COB products tends to be stable, and has recently been gradually applied to outdoor lighting, including LED industrial and mining lamps, street lamps and other markets. Because high-power LEDs and COB LEDs have product design advantages and high light power that are not available in medium power, they will enhance the competitive advantage of the high-end lighting market. International manufacturers have a complete COB product line, focus on product light quality, reliability and light intensity, resulting in high customer use groups, while having IP protection, becoming the main supplier of choice for major export lighting manufacturers. Chinese manufacturers rely on cost-effective and large domestic demand market to develop EMC-packaged COB products, driving the rapid growth of COB revenue for lighting. In terms of 2015 rankings, Citizen (Citizen Electronics) and CREE were the first and second place respectively, and Citizen took the largest market share with its fairly complete product line. In 2015, Citizen and CREE all developed high-intensity COB product lines in an all-round way, and actively entered indoor commercial lighting below 10 watts and 50 watts of engineering and outdoor lighting at a cost-effective price. This year Citizen and CREE launched COB products for the plant lighting market, and revenue is expected to grow substantially.
