The description of LED

LED (Light Emitting Diode), light-emitting diode, is a solid state semiconductor devices, which can be directly converted into electricity to light. LED is the heart of a semiconductor chip, the chip is attached to one end of a stent, is the negative side, the other end of the power of the cathode, the entire chip package to be epoxy resin. Semiconductor chip is composed of two parts, part of the P-type semiconductor, it inside the hole-dominated, the other side is the N-type semiconductor, here is mainly electronic. But linking the two semiconductors, among them the formation of a "PN junction." When the current through the wires role in this chip, will be pushing e-P, P zone in the hole with electronic composite, and then to be issued in the form of photon energy, and this is the principle of LED luminescence. The wavelength of light that is the color of light, is formed by the PN junction of the decisions of the material.

The history of LED

50 years ago, people have to understand semiconductor materials can produce light of the basic knowledge, the first commercial diodes in 1960. English is the LED light emitting diode (LED) acronym, and its basic structure is an electroluminescent semiconductor materials, placed in a wire rack, then sealed with epoxy resin around, that is, solid package, Therefore, the protection of the internal batteries can play the role of line, so the seismic performance LED good.

LED is the core of the P-type semiconductor and components of the N-type semiconductor chips, the P-type semiconductor and N-type semiconductor between a transition layer, called the PN junction. In some semiconductor materials in the PN junction, the injection of a small number of carrier-carrier and the majority of the extra time will be in the form of light energy to release, thus the power to direct conversion of solar energy. PN junction on reverse voltage, a few hard-carrier injection, it is not luminous. This use of injection electroluminescent diodes is produced by the principle of light-emitting diodes, commonly known as LED. When it in a positive state of the work (that is, at both ends with forward voltage), the current flows from the LED anode, cathode, semiconductor crystals on the issue from the ultraviolet to infrared light of different colors, light and the strength of the currents.

Instruments used for the first LED light source instructions, but all kinds of light colored LED lights in traffic and large screen has been widely applied, have a very good economic and social benefits. The 12-inch red traffic lights as an example, is used in the United States have long life, low-efficiency 140 watt incandescent lamp as a light source, it produced 2, 000 lumens of white light. The red filter, the loss-90 percent, only 200 lumens of red light. In the light of the new design, Lumileds companies have 18 red LED light source, including the loss of circuit, a total power consumption of 14 watts to generate the same optical effect. Automotive LED lights is also the source of important areas.

For general lighting, people need more white light sources. The 1998 white LED successful development. This is the GaN LED chip and Yttrium Aluminum Garnet (YAG) package together cause. GaN chip of the Blu-ray (λ p = 465nm, Wd = 30nm), made of high-temperature sintering of the Ce3 + YAG phosphors excited by this Blu-ray after irradiating a yellow, the peak 550 nm. Blue-chip installed in the LED-based Wanxing reflection in the cavity, covered with a resin mixed with YAG thin layer, about 200-500 nm. LED-based tablets issued by the Blu-ray absorption part of the phosphor, the phosphor another part of the Blu-ray and a yellow light mixed, can be a white. Now, the InGaN / YAG white LED, YAG phosphor by changing the chemical composition of the phosphor layer and adjust the thickness of the 3500-10000 K color temperature can be colored white. This blue LED through the method by white, constructed simple, low-cost, high technology is mature, so use the most.

LED:how to install power supply

First step: calculate the total power module, the LED switches to configure the appropriate power supply (80% power output configurations). Total = number of modules x module power consumption power consumption such as 300 three lights 3528 SMD LED module, the rated power is 300x0.25=75W

Second step: fix the module. module fixed mode: 1. preliminary fixed plastic shell back double sided adhesive, then fixe with glass glue. 2. use glass glue directly fix; module surfaces should be wiped clean before installation or proper sanding, make sure the contact surfaces clean. 3. the plastic shell should with screws at the bottom.

Third step: connect the power supply after all modules installed, use 0.75mm or 18AWG wire connected to the power supply. Distance between power supply and modules should be 5 meters or less. If a larger font size, without affecting the module heat sink case, power supply can be built inside.

The development prospects of the mainland State LED

LED doomed its huge market will develop into a huge industry. Overall, the domestic industry in terms of size has been unsatisfactory, the typical case is the integrated circuit industry and the LCD panel industry, the domestic IC industry is now tail between its people, LCD panel industry is riddled with illness, technology complex, large investment and a weak infrastructure is the main reason, while the LED industry will break the curse, and can bring about the upgrading of industries, such as the domestic industry in LCD driver chips simply do not drive, because the LCD panel industry out of the country, support because of huge market, LED Driver IC is expected to flourish in the country to promote domestic enterprises bigger and stronger, which in turn will promote the domestic LCD driver chip or other chip-driven development.

We believe that the LED industry in China has good prospects for development, based on the following points: First, in terms of the technology, LED technology has the bottleneck of high growth, low-threshold characteristics of the study, the domestic long-term accumulation in the semiconductor field of research resources can be useful with a good basis for further study. Although the manufacturing of integrated circuits based on weak, relatively low technological level, but some domestic enterprises to join overseas technical personnel, continue to make breakthroughs in technology, technological level of domestic enterprises with good companies with the technological level of Taiwan or less the same as with international companies as a whole has been narrowing the gap; Second, LED invested relatively small initial investment will be 100 million plant, the domestic enterprises to enter the threshold of the low, easy to achieve a rolling development and manufacture of integrated circuits and liquid crystal panel manufacturers easily to tens of billions of billions of yuan in investment it is "insignificant" easier access to the domestic enterprises to form industrial clusters, of course, may also lead to vicious competition and to a certain stage of development of market integration; Third, the domestic market great, LED market is the next major general lighting market, the market capacity, end-consumer market, scattered and difficult to form a monopoly, a vast living space of domestic enterprises; Fourth, some companies have a core of intellectual property rights, such as crystalline silicon photovoltaic substrate can GaN-ray projects, Dalian Road, the area of the United States and the core of the chip technology, has global competitiveness of these enterprises on technology development in the demonstration effect easy to form and promote the healthy growth of the domestic business market; five, after maturity of the technology, LED downstream packaging and devices are labor-intensive production, the development of the mainland with the labor cost advantage.
