The Characteristics of Solar Street Light in Parks
The solar street light system refers to an independent distributed power supply system. It is not restricted by geographical area, not affected by the installation site. Besides, when installing the solar street light, there is no need to excavate the road for wiring and pipe buried construction. On-site construction and installation are very convenient, and it does not require a power transmission and transformation system. It is environmentally friendly and energy-saving, and can bring good comprehensive economic benefits. It is very convenient to add solar street lights to the roads which have been built.
There are many garden lights in parks. The unique secondary optical design of the LED street lamp holder makes the light of LED street lamp holder light up the area that needs light, and further improves the illumination efficiency to achieve the purpose of energy saving. The LED light source efficiency is currently up to 90-110LM/W. Theoretically this value is supposed to be 250lm/W. The overall luminous efficiency of the LED street lamp holder is higher than that of the high-pressure sodium lamp.
The light color rendering of LED street lamp holder is much higher than that of high pressure sodium lamp. The CRI (color rendering index) of high pressure sodium lamp is only about 23, while the CRI of LED street lamp holder is more than 75. From the perspective of visual psychology, averagely, to achieve the same brightness, illuminance of LED street lamp holder can be reduced by more than 20% than high-pressure sodium lamps.
Solar street lights in the park are powered by crystalline silicon solar cells. The maintenance-free valve-controlled sealed batteries store electricity. Ultra-bright LED lamps are used as light sources. Solar street lights in the park are controlled by intelligent charge controllers to replace traditional street lights which are powered by public grid. No need to lay cables, no AC power supply instead of DC power supply and no electricity bills, which are three of the advantages of solar street lights in the park.
They are mainly applied to urban roads, residential squares, industrial parks, tourist attractions, park green belts and other places. Solar street light is under the control of the intelligent controller. The solar panel absorbs the solar light and converts it into electricity. During the day, the solar cell modules charge the battery pack, and at night, the battery pack provides power to the LED light source to provide lighting.
