Bright future! Full resolution LED light source technology editor
LED light will illuminate the future
60 years since the 20th century, light emitting diode (LED) since the invention of this new type of widely used light source on the screen, lights, landscape lighting, light and other fields. In our daily use of light equipment, LED and incandescent lamps are, tied for the top three fluorescent lamps, LED light source can be said to have been deep into our lives.
LED appears in the beginning, its more of a common light source appear. But with the technology, LED applications in the field has become even more broad, including LED
TV
, LED display, LED printer, LED
Projector
Products have emerged. Other than incandescent and fluorescent lamps, LED light source shortest appear, but precisely because of this, its own strengths is more. It can be said, LED light source has been identified as the next most important source. Here, the writer's technical characteristics for the LED light source of a preliminary study with you.

LED commonly known as light-emitting diode, is a direct light energy into electrical energy to light-emitting display devices. GaAs LED made by earlier, as technology advances, and now they use a gallium phosphide (GaP) and other semiconductor materials. The biggest feature is the LED has a luminous efficiency, energy saving environmental protection, fast response, resistance to vibration.

LED light source can be the first issued to the color is red, into 90 by the end of the 20th century, LED has been able to send red, blue, orange, yellow, and green monochrome. In the end, into 1998, the white LED light source R & D success, and now the three-color RGB LED light sources have also been large-scale application. In our common display devices, the most common is the color white LED and RGB tri-color LED.
Around the advantages of LED light source
Light than ordinary equipment, LED light source with energy saving, high luminous efficiency, wide color gamut and so on, which is most of the shortcomings of traditional light sources.
The previous article, we mentioned the most current source for the incandescent, fluorescent and LED lights. In the light effect, the incandescent light effect in the 12-24 lumens / watt, fluorescent light efficiency was 50-120 lumens / watt.
According to information, white LED light source in 1998 when the recently launched energy efficiency of light is only 5 lm / W, when the light effect in 2005 has up to 50 lumens / watt, 2015 LED light effect may be achieve 150-200 lumens / watt. In addition, the industry statement, LED price of the original 10 had dropped to 1 / 10, while the performance will increase 20 times.
Short life of ordinary bulbs

Most readers know, our family frequently used incandescent lamps have a shorter life expectancy, etc., usually need a year or two to replace the light bulb, and LED bulbs theoretical value of up to 100,000 hours (usually nominal to 20,000 hours), life expectancy above 10 years, LED bulbs also greatly reduces the cost of user input, maintenance or replacement later.

LED dot matrix LED is generally used, if you need a higher brightness LED bulbs thousands of permutations and combinations. However, LED light bulb fast response, especially in the large screen display, you can use to change the characteristics of rapid switching of different images.
We mentioned above, the current is divided into RGB LED RGB and white LED. White LED cheaper, lower power consumption, while the RGB LED color gamut wider expensive. LED backlight in the TV, monitors, notebook screens applications to ensure a longer life, lower power consumption, wider color gamut, color and more uniform. Meanwhile, LED light source also make these electrical planar (LED screen thinner).
LED bulbs because they do not contain mercury, pollution of the environment are greatly reduced. In addition, LED light source also has anti-vibration characteristics of a wide color gamut.
