ED street lamp is different from ordinary street lamp, LED light source adopts low voltage DC power supply, high efficiency white light which is synthesized by GaN based blue LED and yellow color. It has the advantages of high efficiency, energy saving, environmental protection, long life, fast response, high color rendering index, and can be widely used in road. The outer cover can be made of high temperature resistant, low temperature resistant up to 135 degrees, -45 degrees.
Advantage
1, the characteristics of one-way -- light, no light diffusion, ensure light efficiency.
2, LED street lamp has a unique two optical design, the light irradiation of LED street lamp to the area of the need to further improve the illumination efficiency, in order to achieve energy saving purposes.
3, LED has reached 110-130lm/W, but there is still a lot of room for development, the theoretical value of 360lm/W. And high-pressure sodium lamp luminous efficiency is with the power increase will increase. Therefore, the overall luminous efficiency of LED street lamp is better than high voltage sodium lamp strong; the overall light effect is theoretically actually 250W high pressure sodium lamp light efficiency higher than LED lamp).
4, LED street lamp light display color is much higher than that of high pressure sodium lamp, high pressure sodium lamp Hin color index only 23%, and LED street lamp significantly color index reached more than 75, from the perspective of visual psychology, achieve the same brightness, LED street lamp illuminance average decreased more than 20% compared to the high-pressure sodium lamp.
5 and small light attenuation, attenuation of a year of less than 3%, the use of 10 years still reached the requirements of the road, and high pressure sodium lights decline, about a year has dropped more than 30%. Therefore, LED street lamp in the design of the use of power can lower than the high-pressure sodium lamp.
6, LED street lamp has automatic control energy saving device, can achieve the maximum possible to meet the requirements of different periods of lighting power, save energy. Can realize the computer dimming, time control, light control, temperature control, automatic inspection and other human functions.
7, long life: can use 50000 hours or more, to provide three years of quality assurance. The shortage is that the power supply is not guaranteed.
8, high light efficiency: using more than 100LM above the chip, compared with the traditional high pressure sodium lamp can save 75%.
9, easy installation: no need to add buried cable without rectifier, directly to the installation in pole connected or nested source original shell.
10, excellent thermal control: the summer temperature control in 45 degrees below, and the use of passive cooling method, the summer heat dissipation.
11, quality and reliability: all the circuit power supply high quality components, each LED has a separate flow protection, without the need to worry about damage.
12, color uniformity: without lens, not to increase the brightness and uniform light color so as to ensure no sacrifice, iris color uniformity.
13, LED does not contain harmful metal mercury, the environment will not cause damage to the environment.
The principle of comprehensive energy saving effect is remarkable, instead of high pressure sodium lamp can save more than 60%.
Maintenance costs are low: compared with the traditional street lamp, LED street lamp maintenance cost is very low, after comparison, less than 6 years to recover all the investment costs.
Shortcomings
1, a single LED power is low. In order to obtain high power, the need for multiple parallel use.
2, low color. The color of the display is not true in LED, which should be analyzed from the distribution of the spectrum, which belongs to the technical problem.
3, spot. Due to the defects of the white LED manufacturing process and the matching error of the reflection cup or lens, it is easy to cause the "yellow circle" problem.
4, LED irradiation uniformity problem. If we do not carry out the two optical design, the LED is more concentrated, so we must carry out the two optical design, so that the intensity of the distribution of the bat shaped.
5, LED light. Compared to small power LED, high power LED lamp light will be much better. But small power LED heat emission is very small. And the power of the LED is a problem that there is no way to solve the problem, and the brightness will be significantly reduced, so power can not be bigger. Now the market is the largest LED Spark street lamp 360W.
