LED: the star of hope - China's LED industry development prospects and # 3

Domestic LED the main application field

in addition to a large number of domestic LED product is used for all kinds of electrical appliances and equipment, instruments and meters, display equipment, mainly concentrated in:

it is a large, medium and small LED display, indoor and outdoor billboards, stadium scoreboard, information display, etc.

2 is traffic lights: the national each big, middle city traffic lights in the city of lights, highways, railways and airports.

3 was light lighting: the outdoor landscape lighting lighting and interior decoration.

4 is for general illumination: portable lighting ( Flashlights, headlights) , low-level lighting ( Corridor lamp, door lamp, lamp) , reading lighting ( The plane, train, car reading lamp) , light microscope, camera flash, desk lamp, street lamp.

5 is safe lighting: the miner's lamp, explosion-proof lights, emergency lights, safety indicator lamp.

six is special lighting: the military lighting ( No infrared radiation) And surgical lights ( No thermal radiation) , medical treatment lamp, crops and flowers special lighting.

the LED application products especially the main parts of semiconductor lighting products, such as driving circuit, bracket, lamps and lanterns, tube, connectors, plastic and metal parts, etc. , the domestic supporting ability is stronger. In LED application products supporting the key to the LED driver IC, have now been silan micro Mr Bei, CLP 18, Shanghai, Beijing space scale like science and technology, nanjing ten units such as the African union (au) and dalian jie code is development and production, its products can be according to different power and different connection way LED constant voltage and constant current drive, especially can directly drive power LED drive circuit has batch production, which will greatly promote the development of LED application.

from the domestic LED application market, building lighting, display and traffic lights combined accounted for 56%, the total market growth is faster, but relatively scattered, technology standard is not unified; In the application of small size backlight and car only 7%.

in the LED application market, mobile phone backlight market, the development of large size backlight, automobile market is the target market relatively concentrated 'ready' market, technical requirement is higher; Future general lighting market relatively concentrated in the segment market, the overall look is more dispersed, but the overall size, and enter the technical threshold is higher, so the backlight, automobile market and the general lighting market is helpful to enter the enterprise steady growth, the gross margin is also higher, in the field of domestic enterprises should be more involved in the layout of this kind of market, to win a broader space to grow up in the future. In the field of lighting driver IC, domestic enterprises are the main research and development stage, more do not do a certain size, there is no driver IC, LED lighting 'bulb' into homes, also, the outbreak of the LED lighting is bound to promote the great development of the driver IC.
