With the people's awareness of environmental protection gradually increased, led lights in our lives in the use of frequency is getting higher and higher, want to say is that everyone in addition to know that led lights have this important feature of environmental protection can be popular, In addition to those advantages can make it long based on our vast lighting market, it is in the use of the work of what is it? Is there a lack of itself? Its color temperature and what color?
First, the principle of led lights
led the most important light is the light-emitting diodes, which is what we said led, it is a semiconductor device that can convert electrical energy into a visible light source, and in this led, set up a chip, by the N-type semiconductor And P-type semiconductors, these two parts will be connected to form a PN junction, so this chip is particularly important when the current through the wafer when the electrons in the P area of energy, and then in the form of photons to produce light source, which That is, led lights can light the principle of where the Department.
Second, the advantages of led lights
Can be used to accept the led lights, it has the following characteristics:
1, led lamp long life Under normal circumstances led lights and other general lights compared to their life are right and wrong
Often long, can reach the use of more than 50,000 hours.
2, led lights can adapt to a variety of state environment, the general energy-saving lamps if it is in the frequent open and closed state is
Very easy to bad, and led lights to adapt to this high state of the work environment.
3, led lamp production, integration of the world's top light production technology, its light source for the surface light source, this light source can
Enough to increase the luminous surface, very close to people's eyes.
4, led light inside the mercury, lead and the like the existence of harmful substances, no pollution to the environment.
Third, the shortcomings of led lights
No matter how good the product has a relative side, although our led lights have so many advantages, but we still can not avoid its one-sided shortcomings:
1, led light source has a strong direction, which requires us to consider the design of the lamp led special optical characteristics.
2, we started in the new led lights when the time to buy, the cost of the first to be more expensive.
3, if the long-term use of led lights and the effect of poor heat, will greatly reduce the life of led lights.
Fourth, led light source characteristics
led light of the light source has a long life, high-tech, multi-transformation, the new green light source four aspects of the characteristics of the reason why it is long life, because led solid cold light source, coupled with the use of epoxy resin packaging High-tech refers to the light source is a low-voltage products, the integration of a technology, image processing technology and other advanced science and technology to manufacture, So the light source is more high-end; and its multi-conversion is led light source is the use of red, blue, green three basic colors to produce any mix can make it produce a different color light source; Finally, the so-called new green light source is led Light source is the use of cold light source, no radiation, glare small, in the use of time will not produce harmful substances.
