LED lighting driver chip
The luminous efficiency of LED exceeds that of incandescent lamp, the light intensity reaches candlelight level, and the color covers the whole visible spectrum from red to blue. These characteristics lead to wider applications, such as car signal lamp, traffic signal lamp, outdoor full-color large display screen and special lighting source.
With the development of LED highlight and multi-color, the application fields are also expanding, from low luminous flux indicator to display screen, from outdoor display screen to medium luminous flux power signal lamp and white light source for special lighting, to high luminous flux general lighting source.
LED display with wide field of view
LED displays have been widely used in stadiums, squares, venues and even streets and shopping malls. The NASDAQ full-color screen on Times Square in the United States is the most famous, with an area of 120 feet × 90 feet, equivalent to 1005m, made of 19 million super bright blue, green and red LEDs. In addition, it also accounts for a large proportion in the application of securities market screen, bank exchange rate screen and interest rate screen, as well as the information screen of Expressway and elevated road.
Various types of traffic lights
Beacon lights and traffic lights have been widely used LED lights. From the use effect, the effect of long service life, power saving and maintenance free is obvious. At present, the peak wavelengths of LED are red 630nm, yellow 590nm and green 505nm. It should be noted that the driving current should not be too large, otherwise the high temperature conditions under the sun in summer will affect the service life of LED.
The airport marker lights, projection lights and omni-directional lights have good reliability, save electricity, avoid maintenance and replace the old signal lights that have been used for decades. They not only have high brightness, but also are particularly bright due to the good purity of LED light color, which is easier for signal recognition.
Lamp for automobile decoration and function
Super bright LED is used in brake lamp, tail lamp and direction lamp of automobile, as well as instrument lighting and interior lighting. It has obvious advantages over incandescent lamp in vibration resistance, power saving and long service life. As a brake lamp, its response time is 60ns, much shorter than 140ms of incandescent lamp. Driving on a typical highway will increase the safety distance of 4-6m.
LCD backlight
As the backlight of liquid crystal display, LED can not only be used as green, red, blue and white, but also as color changing backlight. The LCD on mobile phone uses led to make backlight, which improves the grade of products and has a good effect. The backlight of 15 inch LCD screen made of 8 blue, 24 green and 32 red Luxeon LEDs can reach 120W, 2500 LM and 18000nits. It not only has good color mixing effect, but also has a color rendering index of more than 80.
Lighting
The colorful lights of the city. Due to the improvement of LED brightness and the decline of price, coupled with long service life and power saving, it is easier to drive and control than neon lights. It can not only flicker, but also change color. Therefore, the monochrome, multicolor and even color changing light-emitting columns made of ultra-high brightness LEDs are matched with various color light-emitting units of other shapes to decorate landscape projects such as tall buildings, bridges, streets and squares, It presents a colorful scene with twinkling stars and streamers.
Daily lighting source
The LED light source of the lighting light source is white light. Because the LED light source has no infrared radiation and is easy to hide, and it also has the advantages of vibration resistance, suitable for battery power supply, solid structure and convenient carrying, it will have a great development in special lighting light sources. It is used for lawn lamp, buried lamp, microscope field of view lighting, flashlight, surgeon's headlamp, museum, billboard or painting exhibition lighting and reading table lamp.
Greenhouse lighting
Light is one of the most important environmental factors for plant growth and development. It regulates plant growth and development, morphogenesis, photosynthesis, material metabolism and gene expression. Therefore, greenhouse light supplement is an important way to achieve high quality and high yield. In recent years, LED is more and more widely used in plant factories. LED light source has become a new light source in greenhouse because of its narrow wave width, low energy consumption, small volume, high efficiency, anti-aging and low heat consumption.
