Why choose LED street lights for road lighting transformation
As a new type of urban lighting equipment, LED street lights are widely used in cities to light up the city at night. So what are the advantages of led street lights over traditional street lights?
From the economic summary, for the recent high-pressure sodium lamps, each set is about 1200~1500 yuan; the current LED street lights, according to the difference in power, the price varies greatly, about 2000 yuan. As far as the current situation is concerned, LED street lights are obviously on the high side, but with the passage of time and the advancement of technology, the cost of LEDs will gradually decrease, and the energy efficiency will be further improved.
Summarize and compare from the service life. The service life of LED street lamps should be evaluated based on the life of the whole lamp. High-pressure sodium lamps include light sources, electrical accessories (mainly ballasts, triggers) and lamps, and the average lifespan of sodium lamps for street lamps is about 6,000 hours. LED street lights have a lifespan of up to 30,000 hours, 5 times that of traditional street lights. The difference between LED street lamps and conventional street lamps is that the LED light source adopts low-voltage DC power supply, high-efficiency white light synthesized by GaN-based power blue LED and yellow, which is efficient, safe, energy-saving, environmentally friendly, long-life, fast in response, and high in color rendering index. Unique advantages, can be widely used in roads. The outer cover can be made, high temperature resistance up to 135 degrees, low temperature resistance up to -45 degrees.
advantage
1. Its own characteristics - unidirectional light, no light diffusion, to ensure lighting efficiency.
2. The LED street light has a unique secondary optical design, which irradiates the light of the LED street light to the area that needs to be illuminated, further improving the lighting efficiency and achieving the purpose of energy saving.
3. The LED street light has an automatic control energy-saving device, which can achieve the maximum possible power reduction and save energy under the condition of meeting the lighting requirements of different periods. It can realize computer dimming, time-segment control, light control, temperature control, automatic inspection and other humanized functions.
4. Long service life: It can be used for more than 50,000 hours and provides a three-year quality assurance. The disadvantage is that the life of the power supply is not guaranteed.
5. High luminous efficiency: Using chips of ≥100LM or more can save more than 75% of energy compared to traditional high-pressure sodium lamps.
6. Easy installation: no need to bury cables, no rectifiers, etc., directly connect to the lamp pole or nest the light source into the original lamp shell.
7. Excellent heat dissipation control: The temperature is controlled below 45 degrees in summer, and passive heat dissipation is adopted, and the heat dissipation guarantee in summer is insufficient.
8. Reliable quality: The circuit power supply adopts high-quality components, and each LED has its own over-current protection, so there is no need to worry about damage.
9. Uniform light color: no lens is added, and uniform light color is not sacrificed to improve brightness, so as to ensure uniform light color without aperture.
10. LED does not contain harmful metal mercury, which will not cause harm to the environment when it is scrapped.
