LED spot light is the use of light-emitting diode as a light source of the spotlights. Traditional lighting more use of halogen lamps, luminous efficiency is low, more power consumption, exposure to ambient temperature rise, short service life.
LED in the light principle, energy saving, environmental protection level are far superior to traditional lighting products. And LED luminous unidirectional to form a perfect support for spotlights with light.
LED spot lights the Chinese name is the United States to light-emitting diodes, it is now the most concerned about the new high-tech industries, the current LED as a light source made more and more lamps, one of the most acclaim is the LED spot lights, because Compared with other LED lamps, LED spot lights lower prices.
1. LED lighting using low-voltage direct current can be driven: a small load, the advantages of weak interference, the use of lower environmental requirements.
2. LED lighting can better control the composition of the luminous spectrum, which can be well used in museums and exhibition hall in the local or key lighting.
3. LED light spot light is very strong: brightness attenuation is much lower than the traditional light source, LED lighting prices civilian population. 4. LED lighting response time is very fast: in the microsecond level, as long as the switch is open, immediately will be bright, there will be no delay and flashing phenomenon.
5. LED spotlights issued by the light energy concentration is high: concentrated in the smaller wavelength window, high purity.
6. Life is very long: generally between 50,000 to 100,000 hours, because the LED is a semiconductor device, even the frequent switch, it will not affect the service life.
7. Environmental protection is good, LED lighting in the production process do not add "mercury", do not need to inflate, do not need glass shell, good impact resistance, good shock resistance, easy to break, easy to transport, very environmentally friendly, known as "Green energy", LED spotlight price of civilians.
8. Energy: LED spot lights is almost all of the spectrum focused on the visible frequency band, the luminous efficiency of up to 80 ~ 90%. Most people think that energy-saving lamps can be energy-saving 4/5 is a great initiative, but LED spot lights than energy-saving lamps but also energy-saving 1/4, which is a solid light source greater reform.
In addition, LED spot lights also has other advantages, high light quality, basically no radiation, LED spot lights prices civilians, are typical of green lighting; reliable and durable, maintenance costs are extremely low and so on. Because LED spot lights has more than other solid light source can not match the characteristics of 10 years after the LED spot lights industry will be the mainstream light source.
The LED provides a half-width monochromatic light. Since the bandgap of the semiconductor decreases with increasing temperature, the peak wavelength of the emission increases with increasing temperature, that is, the red shift of the spectrum and the temperature coefficient is +2 ~ 3A /. LED luminous brightness L is proportional to the forward current. The current increases, the luminous brightness is also approximately increased.
LED lamp life:
LED spot lights as a result of solid light-emitting diode as the light source of light, life depends on the solid LED light source and drive the heat part of the current LED light source life has reached more than 100,000 hours, with the continuous development of LED technology and application of a large number of Universal, in the drive and cooling is also basically to achieve a more ideal state, the sale of high-quality LED lighting life of 10,000-50000 hours, almost 10-50 times the ordinary halogen spotlights.
LED lighting products, energy saving up to 80% or more, almost maintenance-free, there is no need to frequently change the parts of the problem, about half a year down the cost savings can be exchanged for the cost. Green environment-friendly semiconductor light source, light soft, pure spectrum, is conducive to the protection of workers and physical health.
LED lighting design concept:
The emergence of LED to break the traditional light source design methods and ideas, there are two latest design concepts.
1 scene lighting
To the needs of the environment to design lamps. Scenic lighting to place as a starting point, to create a beautiful, brilliant lighting environment, to contrast the scene effect, people feel the scene atmosphere.
2 mood lighting
To the needs of people to design lamps. Emotional lighting is based on human feelings as a starting point, from the human point of view to create a mood-like lighting environment.
