Application and classification of LED

 

Car lighting: The interior of the car includes indicator lights such as the instrument panel and speakers, and the exterior of the car (the third brake light, left and right tail lights, direction lights, etc.) The series uses high-brightness LEDs, and among the carmakers, Toyota also took the lead in replacing the backlight panel of the dashboard with high-brightness LEDs. If you add front and rear lights, brake lights, traffic signs, etc., traffic-related shopping malls have huge business opportunities. In the traffic sign market, there are about 20 million traffic signs in the world. If 2 million are updated every year, the business opportunities can be continued for 10 years.

 

Backlight lighting: mainly in terms of mobile phone backlights, it is the largest market for SMD-type products. Although the growth rate of mobile phones has slowed down significantly in the past two years, there are still 400 million units in the whole year. If a mobile phone requires 2 LED backlights and 6 SMD LEDs for buttons, the annual demand for a conservative 400 million mobile phones is about 400 million. 3.2 billion LEDs. The recent trend of blue-backlit mobile phones in South Korea has made the market demand for blue-light LEDs oversupplied. It is obvious that mobile phones still occupy an irrelevant position in the LED application market. Following the Blu-ray mobile phone, the shopping mall is now the world of color screen mobile phones. In the past, color-screen mobile phones were extremely high-end products, but this year‘s decline in the price of major components has narrowed the price gap between color-screen mobile phones and monochrome mobile phones. Coupled with the vigorous promotion of manufacturers, the wave of mobile phone models has quietly occurred.
