Energy conservation and sustainable development is no longer a question of selective, but will do for the future development of the world today. Represented by the LED lighting to replace traditional light source of new light source, lighting industry is causing a huge change. This kind of new light source lighting products are constantly updated, driven by innovative technology from incandescent bulbs to energy-saving lamps, halogen lamps to LED lights, realized energy saving lighting products to upgrade at the same time, also get a better promotion in the comfort, lighting effect is also more diversified. As the representative of green energy-saving light source, LED lighting industry to become the most potential market hot spots, relative to the light source of technology is more mature, leds have what advantage?
(1) save energy: LED the spectra of almost all concentrated in the visible light spectrum, the luminous efficiency of up to 80-90%. The author will also LED to ordinary incandescent lamp, spiral energy-saving lamps T5 trichromatic fluorescent lamps and done some comparison, the result shows: the ordinary incandescent light efficiency of 12 lm/w, life is less than 2000 hours, spiral energy-saving lamp luminous efficacy of 60 lm/w, life is less than 8000 hours, T5 fluorescent lamp is 96 alm/w, life is about 10000 hours, and a diameter of 5 mm white LED to 20-28 lm/w, life can be greater than 100000 hours. It was forecast, the future of the LED ceiling will be infinite life.
4/5 people think commonly, energy-saving lamps save energy is a great invention, but the LED energy saving a quarter than energy-saving lamps, this is a solid light source is more great reform. In addition, the LED also has other advantages, the light quality, basically no radiation, belongs to typical green lighting source; Reliable and durable, maintenance cost is very low and so on. Because the LED has above other solid light source is unmatched features, 10 years later, LED lighting industry will be the mainstream of the light source.
(2) security environmental protection, low voltage LED work, more than 1.4-3 v. Ordinary LED working current is only 10 ma, ultra-high brightness but also 1 a. Leds don't add "mercury" in the process of production, also do not need air, do not need glass shell, good impact resistance, good shock resistance, invulnerability to breakage and facilitate transportation, very green, known as "green energy".
(3) the long service life: LED small volume, light weight, shell for epoxy resin encapsulation, not only can protect the internal chip, also has the ability of pervious to light condenser. LED the service life is generally between 50000-100000 hours, because the LED is a semiconductor device, even frequent switch, also won't affect the service life. At present domestic lighting mainly USES incandescent lamp, fluorescent lamp and energy-saving fluorescent lamps.
(4) fast response: LED the response frequency f tau and minority carrier injection of tau MC about life, such as GaAs material made of LED, the tau MC generally range between 1-10 ns, the frequency response of about 16-160 MHz, such a high response frequency for video signal display 6.5 MHz is enough, this is one of the key factors to realize video LED large screen.
At present, the LED the minimum response time has reached a microsecond, generally for a few milliseconds, about 1/100 of the ordinary light response time. Thus can be used in a lot of high frequency environment, such as car brake lights or status lights, car after the vehicle's braking can shorten the time, so as to improve safety.
(5) high luminous efficiency: incandescent lamps, halogen tungsten lamp lights for 12 to 24 lm/w (lumens/watt), fluorescent lights for 50-70 lm/w, sodium lamp's light efficiency is 90-140 lm/w, most of the electricity into heat loss. And LED lighting complemented by up to 50-200 lm/w, and good monochromaticity, narrow spectrum of light, can be directly without filtering emit colored visible light.
(6) of LED components, small volume, facilitate its layout and design of various equipment, and better able to achieve "didn't see the light source for the lights in the night scene lighting effect.
(7) high concentration: LED light energy concentrated in smaller wavelength window, high purity.
(8) LED strong directivity: brightness attenuation is much lower than traditional light.
(9) LED low voltage direct current (dc) can drive: has the advantages of small load, weak interference, the use of environmental requirements is low.
(10) can better control of luminescence spectrum: so that they can well used for local or accent lighting in museums and galleries.
(11) can be controlled semiconductor light-emitting layer, semiconductor materials forbidden band width size: to make all kinds of colors of light, and a higher chroma.
(12) high color rendering: won't cause harm to people's eyes.
As an emerging technology, semiconductor lighting industry is still in a rapid development stage, the progress of science and technology make us feel happy, but we have to realize both in technology and the rules and regulations of the industry, compared with the traditional light source, are still not mature is not sound. To truly realize LED instead of traditional light source and a long, long way to go, believe that by promoting the healthy and orderly development of the industry, constantly gradually to transform traditional industries, to speed up the pace of application of promoting industrial structure adjustment, will open the energy conservation green quality life for people.
