LED lights challenge traditional bulbs to enhance brightness and luminous efficiency is the center of gravity

Have absolute effect on the development of LED market and the market size of the foundation in 2001, LED entered the mobile phone market, the overall market showed the first wave of rapid growth, especially the high brightness LED market in 2001~2004 years to achieve the annual growth rate of up to 46%. But 04 years later, with a color screen mobile phone more than 80% white LED display backlight to slow down, coupled with China's Taiwan region and South Korean manufacturers have launched the keyboard with the low price of LED, the LED price decline significantly. In the absence of new market driven, the impact of sluggish growth in the old market base, after the 2005 global LED market fell into a low growth trend.

Global energy prices in early 2008, with the advantage of energy saving LED has become a promising star industry, one after another new manufacturers across the LED industry. Optimistic about the LED industry in the lighting market and LCD backlight market penetration growth, continued expansion. In an optimistic market situation, 08 years from the third quarter of the global financial tsunami affected by market demand, in addition to instant freezing, lighting and other emerging market penetration is not as high as expected, Christmas light string, small size display backlight is the market also because of consumer purchasing power decline, decline phenomenon.

Due to a slowdown in demand, consumption at the beginning of the year to expand its production capacity, product price leads to huge downward movements, the overall market boom from prosperity to decline, but the market growth in the first half, the first half of the market downturn to offset part of 08 years, the global LED Market in 2007 a slight increase of 3%, $6 billion 760 million.

Product structure has not changed significantly, high brightness LED is still the mainstream products. The individual product analysis, in 2008 the global LED product portfolio changes little, high brightness LED is still the main product types, but by the impact of the global financial tsunami, led to a decline in consumer spending power, the general brightness and not visible (infrared) LED market and market share decline.

Four compounds and GaN series compounds made of high brightness LED, brightness, luminous efficiency and other product characteristics continue to grow, so that its application continues to expand. Especially in the large size LCD display backlight market, at the beginning of the NB and LCD-TV into LED backlight module drive, offset the financial turmoil on the market slowdown in demand shocks, the size of the market still maintain 5% growth, market share increased to 72%.

In the past few years, the general brightness of LED, due to its low price, high reliability of the product, in the toy, decorative lamp string and other parts of the need for high brightness applications, still has a considerable advantage, the product price is also quite stable. Affected by the global financial tsunami, the consumer demand for such products is reduced, the price of the product also showed a decline in the general brightness LED market size compared to the recession in 2007 6%, the market share of a recession in 2007 1%, only 15%.

Affected by the decline in the mobile phone market, as well as in the optical mouse market has complementary laser diode products, the invisible light (infrared) LED market decline of 07 over the past 3% years, the market share fell to 13%.

Portable product market share bottomed out. On the application of market analysis, LED application is quite extensive, for example, electronic products, home appliances, automobiles, traffic signals, billboards and other points need light source or surface light source, are LED application market. Early LED due to lower brightness, mainly applied in the fields of home electronics, electronic toys and other products or point source, since 2000, with the increase of high brightness LED brightness and efficiency of products, portable products (such as mobile phone, PDA, digital camera etc.) use a large number of products as a screen or a key light source, with the portable product market growth, the portable LED products become the largest application market.

07 years in the Chinese Olympic business opportunities and economic growth driven, LED billboard market presents a rare high growth over the years. Enter after 2008, because the Olympic venues have been completed, the relevant manufacturers expect is derived demand, also due to the global economic downturn, corporate advertising spending sharply reduced, making the LED billboards difficult to continue, the market share decline phenomenon.

Portable products, including mobile phones, PDA, DSC, NB, etc., which is the largest mobile phone market, so the phone has become the largest application of a single product market LED. LED saturation in the mobile phone light market, coupled with the decline in the price of LED products, making the average cost per unit of LED mobile phone showed a downward trend year by year in 2004, $3.05, down to $1.25 in 2008. Market saturation and the decline in the use of unit costs, making the mobile phone market with LED shrink, making the portable products with LED market size showed a downward trend year by year. Fortunately, LED began 08 years commonly used in NB backlight, the average unit amounted to about 40, the product price is high, manufacturers active layout, the NB backlight market rapid growth, the negative impact of the market downturn makes the offset mobile phone, portable products market share fell to stabilize check. LED technology continued rapid growth, support industry growth application perspective, although LED has far exceeded the luminous efficiency of incandescent lamp and halogen lamp, even beyond the most fluorescent light source, but in order to expand the application fields of LED, reduce the production cost of LED, LED luminance and luminous efficiency of ascension is still LED Technology Development Center in recent years.

01 years of standard white LED (20mA) luminous efficiency of only 25lm/W, to the beginning of 2009 Nichia white light LED, under the current of 20mA, the luminous efficiency of up to 249lm/W, is the industry's most. High power white LED (350mA) luminous efficiency is also 200
