LED fluorescent light features

At present, the shortcomings of traditional lighting fixtures are becoming more and more obvious, which is reflected in the large power consumption and heat, which is not conducive to the reduction of carbon dioxide. The new lighting tool, LED, was warmly received. Although LED products have received such high praise, at present, it is difficult for LEDs to shake the monopoly position of traditional lighting fixtures in the short term.

Below we mainly analyze a member of the LED family—-LED fluorescent lamp

LED fluorescent lamps are different from conventional ordinary fluorescent lamps. The traditional fluorescent lamp has a filament at each end. The lamp tube is filled with a small amount of argon and thin mercury vapor. The inner wall of the lamp tube is coated with phosphor powder, and the gas between the two filaments emits ultraviolet light to make the phosphor powder. Gives soft visible light. The principle of illumination of the LED fluorescent lamp is that the terminal voltage of the PN junction constitutes a certain barrier. When the forward bias voltage is applied, the barrier decreases, and the majority carriers in the P region and the N region diffuse to each other. Since the electron mobility is much larger than the hole mobility, a large amount of electrons diffuse into the P region, which constitutes injection of minority carriers in the P region. These electrons recombine with the holes in the valence band, and the energy obtained during the recombination is released in the form of light energy. This is the principle of LED fluorescent light.
The main features of LED fluorescent lamps are:

1. Applicability is strong, and the adaptability and reliability are improved in various harsh environments indoors and outdoors.

2, rich in color: consists of three primary colors (red, green, blue) display unit box, so that the electronic screen to achieve rich color, high saturation, high resolution, high display frequency dynamic image

3, high brightness: the use of ultra-high brightness LED, the sun is still visible under long distance

4, the effect is good: the use of nonlinear correction technology, the image is more clear, the layering is stronger

5, strong reliability: using static scanning technology and modular design technology, higher reliability and stability

6, display mode diversification: support multiple display modes
