Code for Installation and Construction of solar street light One, fixed position: one question and two look: 1, One question: Ask the related personnel if there are any pipelines, cables and other facilities that hinder construction 2, second look: Take a look at it: see if there are any obstacles such as cables, wires, and optical cables that hinder the installation and use of the lamp.
Energy saving, that is, the electricity consumed under the same average illumination, the average illumination can't just be the average illumination of the ground! The light intensity of the space has a good prediction for the vehicle coming from a distance, to prevent traffic accidents!
Solar street lamps also play a significant role in local electricity supply, so many people are saying that solar street lamps can be used in some environmentally friendly places. But can solar street lamps be used in some bad places? Because not all places are better, but want to know from some aspects, even if the environment is relatively bad, still can use it.
The LED lamp is a semiconductor Light. It is a kind of high-efficiency solid state light source which can emit light with weak electric energy based on the semiconductor PN junction. At a certain forward bias voltage and injection current, the electrons injected into the holes in P region and N region will emit photons by radiation combination after diffusing to the source region, directly converting electric energy into light energy.
System principle, system working principle is simple, using the photovoltaic effect principle of solar cells, solar panels during the day to receive solar radiation and translated into electricity output, after stored in the storage battery charging and discharging controller, the night when the illumination was gradually reduced to about 10 lux, solar panels around the open circuit voltage of 4.5 V, charge and discharge controller detects the voltage value of the action, the battery to discharge lamp holder. 8 hours after the battery discharge, charge and discharge controller action, battery discharge end. The main function of charge and discharge controller is to protect the battery.
