LED Light Supplier Overcome to Meet the Customer Expectation?

Posted by rraheja on April 19th, 2018

The semiconductor wafer can't emit any lights before being packaged in a bullet form, so the market is composed of two parts , EPI-Wafer and packaging. According to statistic, in 2005 the value of encapsulation has increase 11.4% to .7 billion. Japan is the largest LED production country on the world, accounting for 46% of the world market, followed by China Taiwan with 17%. It's estimated in 2008, the value of world packaging market will be up to USD 9. 1 billion, average increase rate 10.9%.

As another statistic's anticipation, the global requirement of white LED spots 230 v is around 4.5billion pcs, as of 2008, the figure will increase to 9.8 billion which more than doubled, average increase rate closed to 30%. From that We can see how large the market potential is. The biggest application now is mobile phone, having 68% market share at 2005. Due to cell phone market is being saturated, growing slowly, it's still the top application at 2008, but its market share fall down to 40%, while application for automobile and lighting achieve faster growth, from 10% to 22% and 2% to 15%, and for LCD TV and PC, up to 7% and 6%.

According the study of Nomura Research Institute, because the high demand for mobile phone in developed country have passed, the growth rate will slow down, along with the price of white LED decreased significantly result in the white LED market growth calculated by turnover is far less than by quantity, however its still expected in 2005~2010 there is 10% of average growth rate, from .74 billion to .84 billion. The driving force is from white LED back light source required for large dimension LCD screens and car equipments.

Manufacturing techniques of white LED are mainly held in the Japanese company which occupies 72% of whole market. Amidst of that, Nichia solely accounts for 41.2%, Citizen accounts for 17.8%, OSRAM OPTO 13.7%, Toyota Gosei 12.9%. Seeing the promising market, through research and development and production cooperation, many western companies including Fairchild, Agilent and Korean and Taiwan companies get involve in LED market make the competition fiercer. Not only will Nichia's market shrink, but through all sort of rearrangement, some new manufacturing companies will arise.

Application

Besides, automobile needs various of lighting, LED as replacement product Will penetrate this market, first applied to panel and interior light, the application rate is merely 12%-24%, but It is expected that it will raise to 67% by 2008, currently the average amount of LEDs used in panel is around 18 pcs, it will be up to 25 by 2008.

Automobile lighting application includes fog lamps, turn and break lamps etc. These car lights has special requirement includes but not limit to high reliably, long life(above 10 years). White LED itself should have further improve on brightness, luminous flux, lighting efficiency, heat emission. Particular to the front lamp, now the lighting efficiency of halogen lamp in use is 17~20 lm/w, luminous flux approximately 1500 lm, life 300~500 hours yet LED still can't catch up with such performances. As per expectation, car LED will increase from billion at 2005 to billion at 2010, another report indicates automobile adopts white LED as front lamp may account for 10% at 2008.
