Ultra-bright LED can be made into brake lights, tail lights and direction lights of automobiles, as well as instrument lighting and interior lighting. It has obvious advantages over incandescent lamps in terms of vibration resistance, power saving and long life. Used as a brake light, its response time is 60ns, which is much shorter than the 140ms of incandescent lamps. Driving on a typical highway will increase the safety distance of 4-6m. As the backlight source of liquid crystal display, LED can not only be used as green, red, blue, white, but also as a color-changing Silicon Nitride backlight source, and many products have entered the production and application stage. Recently, the LCD screen on the mobile phone uses LED to make the backlight, which improves the grade of the product, and the effect is very good. The backlight source of a 15-inch (1 inch ≈ 2.5 cm) LCD screen made of 8 blue, 24 green, and 32 red Luxeon LEDs can reach 120W, 2500 lm, and a brightness of 18000 nits (nits, cd/m²). The 22 LCD screen backlight has also been made, only 6mm thick, not only the color mixing effect is good, but the color rendering index Zirconia Ceramic Sleeve is also above 80. Large-scale backlight sources, although in the development stage, have great potential. Due to the increase in brightness of light-emitting diodes and the decrease in price, coupled with long life, power saving, and simpler driving and control than neon lights, they can not only flicker, but also change color. The discolored luminous column is matched with various colored luminous units of other shapes, which is very effective in decorating tall buildings, bridges, streets and squares and other landscape projects, presenting a colorful, starry and streamer scene. Many units have produced more Ceramic Tubes than 10,000 meters of LED light beams and tens of thousands of lanterns, which are gradually being promoted. It is estimated that it will gradually expand to form a separate industry. The LED light source as a lighting source should be white light. As a military white LED lighting fixture, some varieties have been put into mass production. Because the LED light source has no infrared radiation, it is easy to conceal, and it also has the advantages of resistance to vibration, suitable for battery power supply, solid structure and easy to carry. It will have great development in special lighting sources. Lawn lamps and underground lamps for private use have been produced on a large scale, and are also used as microscope field lighting, flashlights, surgeon's headlights, museum or art exhibition lighting, and reading lamps. Light is one of the most important environmental factors for plant growth and development, and it has regulatory effects on plant growth and development, morphogenesis, photosynthesis, material metabolism and gene expression. In recent years, the application of light-emitting diodes in plant factories has become more and more extensive. The advantages of LED light sources such as narrow wavelength, low energy consumption, small size, high efficiency, aging resistance and low heat consumption make it a popular choice for many light quality researchers. New light source to use. So far, a large number of LED light sources have been used to study the influence of light environment on the macroscopic shape, yield and quality of plants, as well as the research on the influence of cell microstructure, plant differentiation, and secondary metabolites.
