The Broad Prospect of the LED Light

First, we can foresee that white LED will enter the home to replace the existing lighting. Although the price is more expensive compared to the existing lighting equipment, it still will an inevitable lighting device. We all know that, the wavelength range of the visible spectrum is 380nm ~ 760nm, that is the seven colors of light - red, orange, yellow, green, cyan, blue, purple which can be felt by the eyes, but the seven colors of light is only a monochromatic light. The inherent characteristics of the t8 led bulbs determine it is the ideal light source to replace the traditional light source, and it has a wide range of uses. The car lights are also important areas of the LED light source applications.



Second, after the red filter, the light loss is 90%, only leaving 200 lumens of red with long service life. The initial indication of the LED is used as the instrument light source, and later a variety of light-colored LED obtain a wide range of applications in the traffic signal lights and a large area display, resulting in very good economic and social benefits. To make the LED emit white light, its spectral characteristics should include the entire visible spectral range. In some PN junction of the semiconductor materials, the recombination of the injection of minority carrier and majority carrier will release the excess energy in the form of light, which converts electrical energy directly into light.

Third, durable, LED is completely encapsulated in epoxy resin, it is sturdy than light bulbs and fluorescent tubes. In 1998, the white LED was developed successfully. The heart of LED is a semiconductor chip and one end of the chip is attached to a bracket, and one side is the negative, and the other end is connected to the positive power supply, so that the whole wafer is epoxy encapsulated. LED is a solid state semiconductor device, and it can direct convert the electrical to optical. led tube manufacturer forecast that, in 2015, the light efficiency is expected to reach 150 to 200 lm / W LED.

Fourth, small size, LED is basically a small chip encapsulated in epoxy resin inside, so it's very small, very light. The second method is to use a different shade of the chip and packaged together, to produce white light by mixing of the colored lights. When it is in working condition, the current flows from the anode of LED to the cathode, the semiconductor crystals will emit the different colors from the ultraviolet to the infrared light, and the light intensity is related with current.
