A, foreword

BE needy day by day along with the Earth resources, the investment cost of the foundation energy climbs day by day, various safety and pollution are concealed to suffer from it may be said have no place not at, the solar light  energy is a kind of"take it not exert, use it not Jie" of safety, the environmental protection new energy is more and more valued.In the meantime, also along with the Fu technical development of the solar lights  and the progress, the solar energy lamp product economizes on energy in the environmental protection of dual advantage, the application of solar energy street lamp, solar yard light

, lawn light...etc. has already become scale gradually and solar energy's generating electricity in the solar street lamp  to illuminate a realm development has been gradually perfect.The writer is provided to go together a reference for the at 1:00 realize of the design of the solar energy street lamp.

  Two, the solar inground lamp  constitute

  The solar inground light  constitutes to°from several following parts:Solar panel, solar energy controller, storage battery set, Solar Under Ground Light  source, Solar Under Ground lamp  pole and solar street lamp  outer shell.Such as output power supply for communicate 220 Vs or 110 Vs, also need to install negative change machine.

  1, solar panel:

  The solar panel is the core part in the solar LED Lamp , is also a value the tallest part is in the solar street light  lamp.Its function converts the radiation ability of the sun as electric power, or sends to storage battery to save.More widespread in numerous solar LED light  the battery and more and practically have single and crystal Huo solar cell and have another crystal Huo solar wind street light  cell and not- crystal Huo solar signal lights  cell's etc. is 3 kinds.Ample sunshine in the sun light good thing department region, adoption have another crystal Huo solar traffic light  cell is good, because of have another crystal Huo solar cell produce the craft be in brief opposite, price ratio list crystal low.At overcast and rainy day be more, sunlight's being opposite isn't a very ample southern region, adopt the single and crystal Huo solar cell is good, more stable because of single and crystal function parameter of the Huo Solar Warning Light  cell.The not- crystal Huo solar cell is outdoors under the circumstance of sunlight shortage better, only shine on a condition request to the sun because of the not- crystal Huo Solar Traffic Lamp cell lower.

  2, solar caution light  energy controller

  Regardless solar panel  energy lamp size, a character's can goodly refresh to turn on electricity controller is an essential to have.For the sake of the service life of extension storage battery, have to refresh it to turn on electricity a condition to take in to limit, keep storage battery from lead refresh and the depth refresh.At the difference in temperature bigger place, the qualified controller should also have temperature repair function.In the meantime solar energy controller in response to and have the street lamp control the function, have light control, hour control function, and should have a nighttime to automatically slice to control load function, a photovoltaic , easy to overcast and rainy day prolong a street lamp work for time.

   3, storage battery

  Because the solar power systems  light Fu generates electricity the importation energy of system very unsteady, so generally need to install storage battery system then can work.Generally have the lead the sour storage battery, Ni-Cd storage battery, Ni-H storage battery.The choice of storage battery capacity generally wants to follow a following principle:First is can satisfy under the premise of night lighting, save the energy of the PV system  cell module in daytime as far as possible comes down and still want in the meantime can save to satisfy continuous overcast and rainy day the night illuminate a demand of electric power.The storage battery capacity lead small can't enough satisfy the demand of night lighting, the storage battery leads greatly and on the other hand the storage battery is always placed in Kui electricity appearance, the influence storage battery life span, result in in the meantime waste.Storage battery in response to and solar cell, use electricity burden(street lamp) to mutually match.Can use their relations of a kind of simple method assurances.The solar cell power has to compare the load power high 400% above, the system then can normally work.The electric voltage of solar cell wants more than the work electric voltage of storage battery 20~30%, then can promise normal negative electricity to the storage battery.The storage battery capacity has to compare a load a day to consume quantity Gao 600% above is proper.

  4, solar light  source

  The work electric voltage of LED street lamp is generally 12 Vs or 24 Vs, belong to safe electric voltage, don't do an electricity protection to connect ground.But the LED street lamp metals light the pole should do to defend thunder to connect ground and connect a ground of electric resistance to be no bigger than 10 Mu in Europes.
