Important indicators of whether led solar street lights can be used normally

>

The installation site of the led solar street light should choose the surrounding area with smooth drainage. If there are rivers and puddles within a radius of 10 meters, the water surface of the river and puddles must be 2m lower than the foundation surface; there are no obstructions around (determined according to the height of the installed lamps) and high-voltage lines, etc. Dangerous goods; there are no public facilities such as cables, optical cables, and drainage pipes underground at the installation site.

According to the situation of the construction site, the construction personnel have the responsibility to question the unreasonable selection of the installation site and stop the construction, and report the situation to the relevant person in charge within the first time.

Before construction, prepare the tools required to make the foundation of the solar street light and select the construction personnel with construction experience; choose the appropriate cement strictly according to the foundation map of the solar street light, and the special cement that is resistant to acid and alkali must be used in places with high soil pH; There must be no impurities such as soil that affect the strength of concrete; strictly follow the dimensions of the solar street light foundation plan (construction dimensions are determined by the construction personnel) to excavate the pit along the road; after the excavation of the pit is completed, place it for 1 to 2 days to check whether there is groundwater seepage out.

If there is groundwater seepage, stop construction immediately; 5×Ф80 drainage holes must be added to the bottom of the groove where the battery compartment is placed in the foundation or according to the requirements of the drawings. In the foundation, the upper surface of the embedded ground cage must be level (measured and tested with a spirit level), and the anchor bolts in the ground cage must be perpendicular to the upper surface of the foundation. The installation of solar street lamps can only be carried out after the foundations of solar street lamps are qualified.

What kind of light source is used in led solar street lights is an important indicator of whether solar lamps can be used normally. Generally, led solar street lights use low-voltage energy-saving lamps, low-voltage nano lamps, electrodeless lamps, and LED light sources.

(1) Low-voltage energy-saving lamps: low power and high luminous efficiency, but the service life is 2000 hours, and the low voltage lamp tube turns black, which is generally suitable for solar lawn lamps and garden lamps.

(2) Low-pressure sodium lamps: low-pressure sodium lamps have high efficiency (up to 200Lm/w), and are used less.

(3) Electrodeless lamp: low power and high light efficiency. The lamp can be used under the condition of 22V (pure sine wave, frequency 50 Hz) ordinary commercial power, and its lifespan can reach 50,000 hours. The lifespan of solar lamps is greatly reduced and similar to that of ordinary energy-saving lamps (because solar lamps are all square wave inverse meters) Inverter, solar power 220V output frequency, item position, voltage can not be compared with ordinary commercial power.

(4) LED: led solar street light source, long life, up to 1,000,000 hours, low operating voltage, no need for inverter, high light efficiency, domestic 50Lm/w, imported 80Lm/w, with the advancement of technology, LED's Performance will be further improved. LED as the light source of led solar street lights will be a trend.
