Citing a study by Strategies Unlimited, Compoundsemi Online reports that from 1995 through 2004 the packaged HB LED market grew at a rate of 46% per year in terms of estimated worldwide sales revenue to reach $3.7 billion. The number of companies supplying high brightness LEDs (HB LEDs) exceeds 100 worldwide, but 50% of the market is still controlled by the top five companies, according to the report. Nearly 75% of the packaged HB LED market (in terms of sales revenue) comes from 10 out of the 48 identified companies. The report contends that companies supplying epitaxial wafers and chips to the HB LED merchant market are in a similar situation. The top three of the epitaxial wafer and chip suppliers for the HB LED merchants account for over 50% of the market, and the top 11 suppliers account for 75%.
