Research Content:
I Current Status and Future Outlook of High Luminous Flux, White LED Market
n As demands of LED for liquid crystal backlight decline, those for intense lighting is increasing.
n High luminous flux, white LEDs are what to compete against existing various groups of luminous sources.
n There is no winning against existing luminous sources without absolute price reduction.
II High Luminous Flux, White LED Market
n White LED for liquid crystal TV backlight is shrinking.
n Typical package is small multi-chip with insert-frame type, or large single chip with flat substrate.
n There is a package that has 17,675lm of luminous flux. Competition of price per luminous flux can be expected.
n Developing fluorescent materials with stronger brightness can directly lead to LEDs with better performance.
n Being adopted in lighting may not only be effective to cope with unevenly-colored lights but also to cope with heat shield.
n 6-inch Products are increasing at leading manufacturers and there are many new manufacturers of sapphire substrates, whereas top manufacturer produces 4-inch sapphire substrates.
n Production of GaN chips keeps on expanding in China. Improvement in performance may be seen in future.
n Influx of great current is indispensable for high luminous flux white LEDs to improve performance.
n There are many new promising factors such as GaN, gallium oxide, and silicon for next-generation LED platforms.
n Among efforts of developing GaN single crystal for LED, rather than for power semiconductors, expansion of solution-growth techniques is expected.
n Final goal is to make the price 10,000 yen per inch, but there is room to compete with 80,000 yen per inch.
n As speed of development in luminance efficiency slows down, quality and price have become even more important.
n More than 80% of white LED market used for lighting (in value) is occupied by high luminous flux products.
n High luminous flux products are likely to increase the market share by volume, too.
n Among such high luminous flux products, those with high wattage and voltage are expanding.
n Market share of high luminous flux white LEDs is estimated to reach 43.2% of entire white LED market in 2015.
