Led development overview continued

Third, centralized application areas

China proposes that in 2010, 50% of the light sources will be replaced by semiconductor lamps, saving nearly 100 billion kWh per year, equivalent to the power generation of a Three Gorges project.
Relevant experts believe that urban landscape lighting is currently a more realistic market, because its power consumption and requirements for semiconductor light sources are relatively high. The relevant leaders of the Ministry of Science and Technology requested that the 2008 Beijing Olympic Games and the 2010 Shanghai World Expo be used as an opportunity to promote the application of semiconductor lamps in urban landscape lighting. However, in the long run, general lighting is the largest market, and the semiconductor lamps should enter the home as soon as possible, provided that the development of low-cost, high-power, high-brightness semiconductor lamps is increased.

Landscape lighting market: including architectural decoration, interior decoration, decoration of tourist attractions, etc., mainly used for decorative lighting of important buildings, streets, commercial centers, places of interest, bridges, communities, courtyards, lawns, homes, leisure and entertainment places, and decoration Commercial lighting integrated with advertising.

Automobile market: The automotive market is the fastest growing market for LED applications. It is mainly used for indicators such as instrument panels, air conditioners, and audio in the car, and internal reading lights. The third brake lights, tail lights, turn signals, and side lights outside the car. Wait.

Backlight market: LED as a backlight has been widely used in mobile phones, computers, handheld handheld electronic products and automotive, aircraft dashboards and many other fields.
Traffic light market: Due to the high brightness, long life and power saving of red, yellow and green LEDs, the demand in the traffic signal market has increased significantly. Since the first LED traffic signal was used in Xiamen in 2000, nearly 70% of the city's more than 100 traffic lights have been replaced with LEDs. In Shanghai, it is stipulated that all new traffic lights will use LEDs.

Outdoor large screen display: Because high-brightness LED can produce red, green and blue primary colors, LED full-color large-screen display is favored in the fields of finance, securities, transportation, airport, post and telecommunications; The display has replaced the traditional light boxes, neon lights, magnetic flaps, etc., especially in large stadiums around the world.

Special work lighting and military application: Because LED light source has the characteristics of shock resistance, weather resistance, good sealing, low heat radiation, small size and easy to carry, it can be widely used in special work such as explosion-proof, field operation, mine, military operations, etc. In a place or in a harsh working environment.

Other applications: LED can also be used in light industrial products such as toys, gifts, flashlights, Christmas lights, etc. As an important production base of global light industrial products, China has a huge market demand for LED.
