Foreign companies with ultra high brightness LED leading level

Nichia chemical (plant)

Nichia GaN system is a pioneer in the field of laser and LED ranked first in the world. In the blue and white LED market ahead of other similar enterprises. It is known for its development of blue LED, and it is the largest fine chemical manufacturer in the world of phosphors. Its fluorescent powder production in Japan's domestic market accounted for 70% of the proportion, in the global market share of up to 36%. In addition to the special lamp fluorescent powder, and CRT, PDP, X special special special type, which has become a solid foundation to expand the Nichia LED career. In addition, Nichia chemical also produces magnetic materials, battery materials and thin film materials and other fine chemical products, widely involved in various fields of light.

In the LED production, 70% white LED, the main chip and RGB type monochrome color type two types. In addition, the company is the only one in the world can simultaneously produce blue LED and UV LED two products manufacturers. On this basis, Nichia chemical industry and constantly develop new products, especially in SMD (surface mount) LED type high energy, new products emerge in an endless stream.

October 2004, Nichia chemical developed for 50lm/W high luminous efficiency of white LED. The product successfully before the mass production of about 20lm/W luminous efficiency increased by 2.5 times. With the end of the month, Nichia began to provide a sample of the product to specific customers, and plans to make the monthly production reached 1 million before the summer of 2005. The new LED is mainly aimed at car headlights and lighting market. Its brightness is better than the HID light source, so it is now a big threat to the HID light source (High Intensity Cischarge), which occupies 15% of the market. Nichia chemical plans in the first half of 2006 the official production of the product, and plans in 2007 to HID, and the same price officially sold this more bright products.

Expanded to blue, white LED market as the initiator, the total sales of Nichia also showed an increasing trend, the growth in 1996 from 29 billion yen to 181 billion yen in 2003. During this period, the annual sales of phosphors stabilized at about 30 billion yen. By 2003, LED related products sales have accounted for 85.1% of total sales, to $154 billion. In 2003 the global LED market is about 600 billion yen, therefore, Nichia chemical accounted for about 25% of the global market share.

At present Nichia UV 460nmLED, the external quantum efficiency of 36%, white light emitting efficiency can reach 60 lm/W.

TOYOTA (strain)

If likened the LED to the car, then it can be said that Nichia chemical concept of wheels and engine, and TOYOTA has put forward the concept of synthetic body and tire. 1986, commissioned by honorary professor Akasaki, TOYOTA synthetic use of its own in the automotive parts film technology accumulation, began to expand the development of LED. 1987, commissioned by the development of science and technology development mission delegation, TOYOTA successfully formed on the sapphire LED electrode. Therefore, the synthesis of TOYOTA as the pioneer of blue LED is not too much.

TOYOTA synthesis in the speed of development in recent years is quite fast. 1998, its sales of 6 billion 300 million yen, but in 2002, has grown to $25 billion 200 million. In 2003, due to insufficient light brightness, white mobile phone in Taiwan and South Korea, China adopt a low price strategy and the European display market downturn and other reasons, resulting in the synthesis of TOYOTA failed to complete the planned sales of 34 billion yen, but its sales and profits have reached the highest level in history.

Is one of the largest growth mobile phone special white LED. From 2 billion 700 million yen in 2002 to grow to $12 billion 300 million, accounting for 40% of total sales. The rest are blue, blue-green and 3in1 white LED. 2003, domestic sales accounted for 8, to 23 billion 700 million yen. Overseas sales: 4 billion 700 million yen in asia. In the application, the mobile phone accounted for 72%. In addition, there are more liquid crystal backlight, buttons, back LCD backlight (3in1), etc.. Signal equipment, large screen display and other aspects of the application is also more. 2004, TOYOTA's original plan to sell 42 billion yen, but due to the mobile phone market downturn, so had to revise the sales plan to 30 billion yen.

In order to capture Nichia chemical mobile phone backlight market occupy 90% market share, TOYOTA synthesis intention to improve the brightness of the white LED in the autumn of 2004 the development of brightness level 1000mcd white LED TG WHITE II ", this is better than the original 600 700mcd a lot of bright. Then, TOYOTA combination began to develop 1300mcd white LED.

In car navigation system and LCD computer controller, TV LCD backlight for large is TOYOTA's target market. Lighting application design and development is also in full swing. In addition to the production facilities of TOYOTA. Aichi Heiwa factory in Saga County, Takeo city has established second production bases of production LED GaN LED blue. The total investment of the equipment is 15 billion 600 million yen, and the output is expected to reach about 200 million in the year of 2006. By then the total production capacity of the two plants can reach a monthly production of 420 million, the goal is 2008 LED sales reached $120 billion.

Lumileds

Founded in 1999, Lumileds lighting is the world famous manufacturer LED, a leading position in the automatic lighting, including computer display, LCD TV, lights and general lighting, solid-state lighting applications. The company's patented Luxeon is the first to incorporate traditional lighting with a small needle
