What is the meaning of led lights?

- Aug 24, 2016 -

As people environmental protection consciousness to strengthen gradually, the led lamp in our life, use frequency is more and more high, small make up want to say is, in addition to the known leds have environmental protection is an important characteristic for the popular, in addition to those advantages can make it for a long time base on our vast market of lamps and lanterns, the working principle of it at the time of use? There are deficiencies itself? What it the color temperature of color? Everyone to understand whether a series of questions, in order to be able to make better and more comprehensive understanding of led lights, small make up today is detailed to introduce the knowledge related to led lights.

First, the principle of led lights

Led lamp is the most important in light-emitting diode, led, also is what we call it is a kind of semiconductor devices, can convert electric power into visible light, and in the led, set a chip, is composed of N type semiconductor and p-type semiconductor, connecting the two parts will form a p-n junction, so the chip is particularly important when electric current through the crystal electronic would occur in the P zone energy, and then produce light source in the form of photons, which is where the principle of led lamp can shine.

Second, the advantages of led lights


For the benefit of led lights, it has the characteristics of the:

1, the led long service life. Generally led lamp compared with other general lights up, their lives are

Often long, can reach 50000 hours.

2, led lights can adapt to all kinds of state of the environment, general energy-saving lamps if it is in the open and close frequently is the condition

Very easy to bad, and the state of the led lights can adapt to the high working environment.

3, the production of led lights, is a blend of the world's top light distribution technology, its light source for the surface light source, can this kind of light source

Enough to increase the shiny surface, very affinity people's eyes.

4, led lights inside no mercury, lead, such as the presence of harmful substances, no pollution to the environment.

Three, the shortcomings of led lights

Again good products have a relatively side, although our leds has so many advantages, but we still can't avoid it one-sided disadvantages:

1, the led light source has very strong directivity, this requests us in the design of lamps and lanterns to consider led special optical properties.

2, we listed at the beginning of the new type of led lights to buy, some more expensive cost to the bottom.

3, if the use of led lights for long time and the cooling effect is not good, will greatly reduce the service life of led lights.

Fourth, the led light source characteristics

The led light source is roughly have long service life, high and new technology, transform, features of the new type of green environmental protection light source sifang, say its life is long, because led solid cold light source, and using the epoxy resin encapsulation, so all aspects of the performance is also relatively strong, not easy to appear the phenomenon such as thermal deposition, droop; High and new technology is to point to the led light source is low voltage products, combined with computer technology, image processing technology and other advanced science and technology to manufacture, so light is high; While its transformation refers to the led light source is the use of red, blue, green three primary principle to make arbitrary mixed can produce different colors of light; The last of the new type of green environmental protection light source refers to the led light source is to use cold light source, no radiation, glare small, at the time of use does not produce harmful substances.
