Application and classification of LED

Application and classification of LED LED lighting is widely used in outdoor large-screen display, urban architectural landscape lighting, mobile phone, notebook, TV backlight, car lamps and solar LED lighting, etc. The space used is continuously upgraded, and the proportion of the market is also expanding. The following is a comprehensive classification of the application of LEDs. LEDs are roughly divided into five major areas: backlight, lighting, electronic equipment, display screens, and cars. Car lighting: the interior of the car includes indicators such as dashboards and speakers, and the exterior of the car (third brake lights, left and right tail lights, direction lights, etc.). The series uses high-brightness LEDs, and among the automakers, Toyota is the first to replace the backlight of the instrument panel with high-brightness LEDs, and other automakers are also adopting high-brightness LEDs for their new cars.

If you add front and rear lights, brake lights, traffic signs, etc., there are huge business opportunities for traffic-related shopping malls. In the traffic sign market, there are about 20 million traffic sign lights in the world. If 2 million are updated every year, the business opportunities can last for 10 years. Backlight lighting: mainly mobile phone backlight, which is the largest market for SMD products.

Although the growth rate of mobile phones has slowed down significantly in the past two years, there are still 400 million units of mobile phones in the whole year. Based on the calculation that 1 mobile phone requires 2 LED backlights and 6 SMD LEDs for buttons, the conservative demand for 400 million mobile phones a year is about 3.2 billion LEDs. After Blu-ray mobile phones, the market is now dominated by color-screen mobile phones. In the past, color-screen mobile phones were extremely high-end products, but this year, the price of major components has fallen, which has narrowed the price difference between color-screen mobile phones and monochrome mobile phones.
