LED’s advantages:
Energy-saving: (1) LED the spectra of almost all concentrated in the visible light spectrum, the luminous efficiency of up to 80 ~ 90%. Reporters will also LED to ordinary incandescent lamp, spiral energy-saving lamps T5 trichromatic fluorescent lamps and done some comparison, the results showed that 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 lm/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 street lighting 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) environmental protection: in the process of production of LED don’t add “mercury”, 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) life is very long, generally between 50000-100000 hours, because the LED street lighting is a semiconductor device, even frequent switch, also won’t affect the service life
(4). The volume of LED components is very small, more convenient to all sorts of equipment layout and design, and better able to achieve “didn’t see the light source for the lights in the night scene lighting effect
(5) the LED light energy concentration is very high: focused on smaller wavelength window, high purity.
(6). LED very fast response time: in microsecond, as long as the switch is opened, will soon be bright, there will be no delay and flicker phenomenon
(7). The LED luminous directivity is very strong: brightness attenuation is much lower than traditional light.
(9) LED use the low voltage dc can drive: has the advantages of small load, weak interference, the use of environmental requirements is low.
(10) can well control of luminescence spectrum: so that they can well used for local or accent lighting in museums and galleries.
(11) can be achieved by control of semiconductor light-emitting layers of semiconductor materials forbidden band: the size of the picture to make all kinds of colors of light, and chroma is higher,
(12) high color rendering: won’t cause harm to people’s eyes.
But 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 achieve LED instead of traditional light source and a long, long way to go, there are many technical problems need to be solved, such as high power radiator and photosynthetic efficiency. Also want us to LED industry personnel and experts to work together to make the LED to better service for us.
