1, its own characteristics-the light of the one-way, without the diffuse light, to ensure the lighting efficiency.
2, LED street lights have a unique two times optical design, the LED street light to the lighting needs of the area to further improve the lighting efficiency in order to achieve energy-saving purposes.
3, LED has reached 110-130lm/w, but also has a lot of development space, the theoretical value of up to 360lm/w. And the high pressure sodium lamp luminous efficiency is increases with the power increase, therefore, the overall light effect LED street lamp is stronger than the high-pressure sodium lamp; (This overall light effect is theoretically, actually more than 250W high pressure sodium lamp's light efficiency is higher than the LED lamp).
4, LED street light color than high pressure sodium lamp, high pressure sodium lamp color index only about 23, and led street color index reached more than 75, from the visual psychological point of view, to achieve the same brightness, led street lighting average can be lower than high-pressure sodium lamp down more than 20%.
5, light decay small, a year of light decay less than 3%, the use of 10 years still reach the road requirements, and high pressure sodium lamp decline, a year or so has fallen more than 30%, therefore, led street lamps in the use of power design can be lower than the high-pressure sodium lamp.
6, LED street lights have automatic control energy-saving devices, can be achieved in different periods of time to meet the lighting requirements of the most likely to reduce 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 more than 50,000 hours, providing three years of quality assurance. The disadvantage is that the power supply life is not guaranteed.
8, high light efficiency: the use of ≥100lm chips, compared to the traditional high-pressure sodium lamp can save more than 75%.
9, easy to install: No need to embed cable without rectifier, and so on, will be installed directly on the pole or the light source embedded in the original lamp shell.
10, excellent thermal control: Summer temperature control in 45 degrees below, and the use of passive heat dissipation, the summer of the lack of protection.
11, reliable quality: circuit power all the use of high-quality components, each led has a separate overcurrent protection, without fear of damage.
12, light color uniformity: without lenses, not to improve the brightness and sacrifice even light color, so as to ensure that no aperture light color uniformity.
13, LED does not contain harmful metal mercury, in the scrap will not cause harm to the environment.
Comprehensive energy saving effect of the above principle is remarkable, replace high pressure sodium lamp can save more than 60%.
