A kind of solar powered parking lot illuminator
Technical field
The utility model relates to a kind of parking lot illuminator, particularly relates to a kind of solar powered parking lot illuminator.
Background technology
The energy of solar energy is the energy from the outside of the earth celestial body, is the hydrogen nuclei huge energy that fusion discharges when superhigh temperature in the sun, and the overwhelming majority of necessary for human energy is all directly or indirectly from the sun.We live fossil fuels such as required coal, oil, natural gas all be because each kind of plant through photosynthesis solar energy be transformed into chemical energy in plant, stores under after, pass through and form very long geological epoch by being embedded in underground animals and plants again.They come down to the solar energy that is fixed up by ancient biological.
Solar energy is a kind of clean reproducible new forms of energy, more and more receives people's favor, and effect is widely arranged in people's life, work, and one of them is an electric energy with solar energy converting exactly, and solar cell utilizes the sun workable exactly.The operation principle in solar heat power station then is to utilize the sunlight that converges, and burns water to seething with excitement to become steam, is used for then generating electricity.
Utilize solar power generation that two major types are arranged, one type is solar power generation (also claiming the solar energy generating), and another kind of is solar thermal power generation (also claiming solar energy thermal-power-generating).
The solar energy generating is a kind of generation mode that solar energy directly is transformed into electric energy.It comprises photovoltaic generation, photochemistry Generate, Generation, Generator induction generating and four kinds of forms of photo bio generating; It is to be heat energy with conversion of solar energy earlier that electrochemistry photovoltaic cell, photoelectrolytic cell and photocatalysis battery solar energy thermal-power-generating are arranged in the photochemistry generating; Again heat energy is changed into electric energy, it has two kinds of transform modes.A kind of is that solar thermal energy is directly changed into electric energy, like the thermo-electric generation of semiconductor or metal material, and hot electron in the vacuum device and the generating of thermoelectric ion, the alkali metal thermo-electric conversion, and magnetohydrodynamic generation etc.Another kind of mode is that the logical overheated machine (like steam turbine) of solar thermal energy is driven generator for electricity generation, and similar with conventional thermal power generation, only its heat energy is not from fuel, but from solar energy.
The Along with people's growth in the living standard, the owning amount of vehicle is increasing, and it is imperative to set up the complete parking lot system of a cover; And along with process of urbanization, land resource rare makes the parking lot operated by rotary motion underground; The illuminator in parking lot becomes a vital link; Illumination needs bigger electric energy, and solar energy is available environmental protection resource, how to utilize solar energy to become the technical problem that those skilled in the art need to be resolved hurrily for the parking lot powered lighting; Also be to be social energy savings, create the problem of effective value.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of solar powered parking lot illuminator is provided, and has practiced thrift electric energy, and can between solar energy and mains supply, effectively change, and has guaranteed the illumination in parking lot.

Embodiment
Be elaborated with reference to accompanying drawing below in conjunction with embodiment, so that the technical characterictic and the advantage of the utility model are carried out more deep annotation.
The theory structure sketch map of the utility model is as shown in Figure 1; A kind of solar powered parking lot illuminator; Comprise the LED lamp, light-controller that described parking lot illuminator further comprises solar panels, be connected with the solar panels output and the LED lamp that is connected with the light-controller output.
Described solar powered parking lot illuminator further comprises the urban distribution network that is connected the light-controller input.
The light-controller theory structure sketch map of the utility model is as shown in Figure 2; Described light-controller comprises microcontroller; The modulation-demodulation circuit, the protective circuit that are connected with the microcontroller both-way communication reach the power supply change-over circuit that is connected with the microcontroller output with the two-way electric power signal Acquisition Circuit that is connected of modulation-demodulation circuit.
Further, described protective circuit comprises overvoltage crowbar, current foldback circuit and overload protecting circuit.
Further, described power supply change-over circuit is a single-pole double-throw switch (SPDT), and an end connects the solar panels output, and the other end connects the urban distribution network output.
The control method of the described solar powered parking lot illuminator of the utility model, its step is following:
Step 1, light-controller are gathered the electric energy of solar panels through the electric power signal Acquisition Circuit, and are transported to and are controller;
Step 2, microcontroller carry out computational analysis to the quantity and the power supply power demand of LED lamp, judge that the electric energy of existing solar panels can be given the quantity of LED lamp power supply;
It is solar powered that the electric energy of step 3, solar panels then all uses enough for the power supply of LED lamp, and the electric energy of solar panels then starts the power supply change-over circuit less than the required electric energy of LED lamp;
Step 4, power supply change-over circuit insert urban distribution network in the LED lamp electric power system, are the power supply of LED lamp with solar panels.
Further, when the electric energy of the described solar panels of step 3 is zero, then all use the urban distribution network power supply.
The Conversion of energy that solar panels absorb is an electric energy; This electric energy is a direct current, is delivered to light-controller, and light-controller flows to the power supply of LED lamp; Rain or at night the time at the cloudy day; The solar panels electricity shortage, the interior power supply conversion circuit of light-controller this moment inserts urban distribution network in the LED lamp electric power system, is the power supply of LED lamp with solar panels.
