LED (Light Emitting Diode), especially white LED, has developed very fast in recent years, and its light efficiency has surpassed some existing light sources, such as incandescent lamps and fluorescent lamps. LEDs are also making rapid progress in landscape lighting and road lighting, thanks to advances in technology and the declining LED prices. With the continuous deepening of the concept of global energy conservation and emission reduction, LED will play an increasingly important role in energy conservation and environmental protection.
The LED industry chain is long, from upstream substrate materials, epitaxy, chips to device packaging and applications, covering the semiconductor industry and the lighting industry. It can be said that LED is a cross-integration industry of various disciplines. LEDs are increasingly used in lighting applications and have now entered the pilot and demonstration phase of indoor and outdoor lighting.
At present, the development of the LED industry, according to our statistics, the overall development of the industry in 2008 is lower than expected at the beginning of the year, obviously this is due to the impact of the 2008 international financial crisis. In 2009, the development of the industry has rapidly improved, and corporate investment and capacity expansion are also accelerating. In terms of upstream extension and chip, technology continues to advance, and investment has increased substantially. However, there is still a gap in technology level in terms of high-end applications such as backlight display and functional lighting. In the middle-end device packaging, the product structure has been significantly improved, especially the functional lighting technology has made a breakthrough, but the scale of the enterprise is generally small, and has not yet entered the medium and large-size backlight, automotive lighting and other applications. Downstream applications can be said to be booming. Applications such as landscapes, displays, and functional lighting are at the forefront of the international market. It can be said that our production capacity is leading globally and the technical level is also significantly improved, but international brands have not yet been formed.
In terms of industrial layout, LEDs are listed as development priorities in more regions. It can be said that the development pattern has begun to change. Domestic cities are actively involved, and more regions have announced the construction of a semiconductor lighting industry base. The pattern of the original four concentrated areas has been broken, and a new industrial structure will be formed within 3-5 years.
In terms of investment, capital attention has risen and accelerated into the LED industry. Private capital is actively involved in investing in the LED industry, and the scale of investment is growing rapidly. The investment field involves the entire industrial chain. In recent years, venture capital has invested more than 1.5 billion yuan in domestic enterprises. In the first half of 2009, LED projects were launched all over the country, and the total investment budget has exceeded 20 billion yuan. The huge order volume of upstream equipment shows the focus and promotion of capital for the LED industry.
Who will use the rapid development of the industry to become an international industry giant like GE and PHLIPS, which is worth looking forward to.
