Led Public lighting(CLASSIC) is different from conventional lighting. LED light source uses low-voltage DC power supply. It is made of GaN-based power blue LED and yellow light. It has high efficiency, safety, energy saving, environmental protection, long life, fast response and high color rendering index. Can be widely used in roads. Available for production, high temperature 135 degrees, low temperature -45 degrees.
Advantages: 1, its own characteristics - unidirectional light, no light diffusion, to ensure light efficiency. 2, LED lights have a unique secondary optical design, so that LED lights shine to the required lighting area, further improve the light efficiency, to achieve energy-saving purposes. 3, LED has reached 110-130lm / W, and there is still a lot of room for development, the theoretical value is 360lm / W. And the luminous efficiency of high-pressure sodium lamp increases with the increase of power, therefore, the overall efficiency LED lamp is higher than the high-pressure sodium lamp (Integrated light effect theory, in fact, the high-pressure sodium lamp above 250W is more efficient than the LED lamp). 4, the light color of the LED lamp is much higher than that of the high-pressure sodium lamp. The color rendering index of the high-pressure sodium lamp is only about 23, and the color rendering index of the LED street lamp is 75 or more. From the visual psychological point of view, the same brightness is achieved, the LED lamp The average light is reduced by more than 20% compared to the high pressure sodium lamp. 5, the light decay is small, less than 3% of the light of one year, the use of 10 years still meets the road requirements, while the high-pressure sodium lamp drops, about 30% drop in about one year, so the LED lamp can use the power supply design can be lower than the high-pressure sodium lamp. 6, LED lights with automatic control of energy-saving devices, can meet the lighting requirements of different time periods, minimize power and save energy. It can realize computerized dimming, time-sharing control, lighting control, temperature control, automatic detection and other humanized functions. 7, long service life: can be used for more than 50,000 hours, providing three years of quality assurance. The disadvantage is that the life of the power supply is not guaranteed. 8, high luminous efficiency: ≥100LM above the chip, compared to the traditional high-pressure sodium lamp can save more than 75%. 9, easy to install: no need to add cables without rectifiers, etc., will be installed directly on the original lamp housing with the light pole or light source nested. 10, excellent heat control: summer temperature is controlled below 45 degrees, and passive heat dissipation, summer heat protection is insufficient. 11, reliable quality: all use high-quality circuit components, each LED has independent over-current protection, no need to worry about damage. 12, uniform light color: no lens, no increase in brightness, sacrifice uniform light color, so as to ensure that the light color is uniform. 13, LED does not contain harmful metal mercury, and will not cause harm to the environment when it is scrapped.
In combination with the above-mentioned principle of remarkable energy saving effect, the replacement of the high pressure sodium lamp can save more than 60%. Low maintenance costs: Compared with traditional street lamps, LED lamps have very low maintenance costs. After comparison, all input costs are recovered in less than 6 years.
