New LED challenge incandescent lamp

Along with the rapid development of semiconductor technology, all kinds of new type of LED (light emitting diode) is challenging the incandescent lamp. In the near future, people will usher in a more brilliant new era of lighting.

In our life and work, people are very familiar with the LED. In the computer, audio control panel and a variety of monitors, you can see its figure. Red, yellow, blue and other colors of light-emitting diodes constantly flashing, as we indicate the state of the machine. Today, modern lighting requires us to develop a red light, yellow light and blue light on the basis of the regeneration of white light emitting diodes.

In order to get emitting white light LED, the scientists propose three solutions: one is through the red, yellow and blue three light mix to produce white light; two white light emission by blue photon triggered phosphorescence; three, is the first two methods, design a "photon recycling" device for producing white light. It is proved that the three schemes are feasible. Now, we need to solve the problem is to find the most simple, the most convenient production, the most effective way. To this end, people are trying to explore.

That experiment, using LED lighting can directly convert electric energy to light. Therefore, it has more advantages than the commonly used incandescent lamp. As is known to all, in October 21, 1879, the American scientist Edison invented the incandescent lamp, so that people bid farewell to the darkness of the night, into the era of electrical lighting. However, the incandescent lamp through the tungsten red, light, for lighting. Tungsten burning red, 3000 degrees high temperature. At the same time, the tungsten filament is constantly being gasified by the high temperature. The life of the bulb ends when it is vaporized to a fine, final break. Some statistics, an incandescent lamp consumes only 12%-18% of its own energy into light energy, and the rest are lost in the form of heat energy. The utility model has the advantages that the utility model has the lowest utilization rate of electric energy in all electric lighting lamps. Moreover, the incandescent lamp is working at high temperature, its service life is usually not more than 1000 hours. The light-emitting diode, luminous efficiency can reach 50 to 100 times the incandescent lamp, the service life of up to 50 thousand to 100 thousand hours, that is, from 5 to 10 years. It seems that the difference between the two is very wide.

According to another report, researchers recently developed an organic light emitting diode OLED light emitting diode manufacturing technology will greatly promote a step forward. The present invention relates to a light-emitting diode, which is processed by inorganic crystal structure material. The new type of organic light-emitting diodes with plastic polymer instead of crystalline structure materials. Because of the thickness of plastic polymer material can reach 1/10 mm, used to process the light-emitting device, as thin as paper. At the same time, the utility model has the advantages of fast running speed, light weight, high brightness, low power consumption, etc., and is very strong, and has excellent impact resistance. The advent of organic light-emitting diodes, not only for lighting, in notebook computers, high-definition television, personal data assistant and the third generation of wireless internet access, but also has a very broad space for development.
