solar led street lamps and good points

LED display screen, LED electronic display screen appears more and more people’s vision, LED lighting is some of the main road on the trial of the LED lights, LED street with what conditions?

solar led street lamps and good points

(1) energy saving voltage, low current, high brightness features. LED lights use LED street must have the characteristics of low voltage, low current, high brightness, ensure that the installation, normal use, energy efficient.

(2) new green light, LED use a cold light source, glare-free radiation not to issue a hazardous substances. The environmental benefits of better LED, ultraviolet and infrared spectra, and recyclable waste, mercury element pollution is safe to touch, is a typical green lighting.

(3) long life. LED street due to the continued use of replacement require a volume to replace them is too much trouble, when selected, long life are also important factors, Sheng Hao of the light produced by LED lighting, the basic use of age in 50,000 hours more fully comply with this condition.

(4) The lighting structure is reasonable. LED lamps will completely change the structure of the lamp, according to different requirements, the structure of the LED lamps to improve the brightness of the initial conditions, after the rare earth again increase the brightness, and the improvement of the optical lens, the brightness. The solid-state light source LED is encapsulated with epoxy resin, glass bulb filament and other easily damaged parts in its structure, an all-solid structure, is therefore able to withstand vibration and shock, without being damaged.

(5) light colors and simple, light and color. Must be used as street lights LED street light color simple, without too much noise at the same time to ensure that the lighting levels need to ensure road safety.

(6) safe. The use of low voltage LED light source, light stable, non-polluting, no 50Hz flicker when the AC power supply, no UV-B band, the color rendering index Ra is close to 100 color temperature of 5000K, closest to the sun the color temperature 5500K. Low heat thermal radiation, cold light source and precise control of the light pattern and light-emitting angle of light color and soft, no glare; without mercury sodium and other elements that might jeopardize the substance of the LED lights.

The application of constant current driver in solar LED street lamps

 

Although there are many methods of use of solar energy are not suitable for China’s national conditions, but like the ultra-high-power solar LED street lamps, the family roof, power generation, only the most simple and most easily implemented solar street lights. The total number of street lights in China more than 100 million, 60 million into a solar street lighting, the annual savings in electricity generating capacity of more than one of the Three Gorges Hydropower Station. Future annual increase of 20 million street lights to switch to solar street lights, three years down a Three Gorges Hydropower Station. Its energy-saving effect is very impressive, but totally does not require launching a campaign to mobilize the country’s power to build, and this launch of local governments at all levels of strength and the power of the enterprises concerned can be completed.

 

The installation of solar street light is also very simple, almost as if planting trees, dig a pit and buried in the family to stay. Unlike the AC lights, Cable-laying and construction of transformer room, dug maintenance well … Although the cost of the cost of a single solar LED street lamps than ordinary high-pressure led high bay lamp is more expensive, but considering the overall cost of the laying of cables, the two are similar. Coupled with substantial annual savings on future electricity, can be said that the savings in electricity of solar street lamps in 2012 can make up the difference, after the savings in electricity is net income.
