Solar street lamps of hebei street light air system from the technical requirements

Solar street light to the technical requirement of the electrical system: 1, the light source, solar energy use special high power LED light source, the design life of 100000 hours or more. 2, the controller has its power consumption is small, and has the battery overcharge, over discharge protection, storage battery open



solar street light to the technical requirement of the electrical system: 1, the light source: solar energy use special high power LED' High power LED refers to the light emitting diode with large rated power. 】 Light source, the design life of 100000 hours or more. 2, the controller has its power consumption is small, and has the battery overcharge, over discharge protection, open, load over-voltage protection battery, solar battery reverse connect protection, delay action, floating, temperature compensation, relating to overtime, moisture protection. 3, using solar energy for 12 v battery valve control type sealed and maintenance-free battery, the service life of more than 5 - For 12 years, temperature range for - 25℃- - 50 ℃, with functions of depth charge and discharge. 4, solar panels, Solar panels, 太阳能板) Is by absorbing sunlight, the solar radiation through the photoelectric effect or photochemical effect directly or indirectly converted into electrical energy device, the main material of most of the solar panel as the 'silicon', but because of the production cost is larger, so it widely used, we still have some limitations. 】 Imported solar cell chip, its conversion rate' Conversion turnover thewire, turnover rate in a certain community, community and ecosystem, standing crop ( Individual number or biomass) Are in a stable, input amount in the agreed upon period of time ( Or output) On the ratio of standing crop called conversion rate. 】 17% or higher, a life of 25 years or more, to fully comply with the solar street lighting.
