Abstract
The utility model relates to a lighting system with highly efficient and non-inverse solar photovoltaic power supply and comprises a solar photovoltaic component, an LED lighting lamp with high brightness, a storage battery, a controller and a main power supply circuit. The solar photovoltaic component is connected with an electricity power input port of the controller, and the low-voltage direct current electricity generated by the solar photovoltaic component charges the storage battery through the controller which provides a protection to the storage battery in charging and discharging. A load output port of the controller is connected with the LED lighting lamp, and under the control of the controller, the electricity power of the storage battery is directly supplied to the LED lighting lamp that works at night in low-voltage direct current without inversion, and the circuit of the lighting lamp is cut off in daytime. When the storage battery is undervoltage, the electricity power input port of the controller is automatically switched to a port of the main power supply which supplies the power to the lighting lamp after voltage reduction and rectification.
Description
Technical field
The utility model relates to a kind of by solar powered illuminator, is specifically related to a kind of low-voltage direct illuminator of non-inversion solar photovoltaic.
Background technology
Present existing electricity supplying and using system with solar electrical energy generation adopts inverter more, the low-voltage DC inversion that solar energy is sent is to use behind the 220V/50HZ or be incorporated into the power networks, when voltage transitions, to lose certain electric energy like this, reduced power consumption efficiency, the complex structure of while inverter, the cost height, and also there is certain potential safety hazard in the high pressure electricity consumption, to very unstable, reduced the reliability of system with the some peak civil power of rationing the power supply, have a power failure.Application of Solar Energy and popularization have been hindered so greatly.Along with the development of society, energy crisis is remarkable day by day.Power-saving technology and energy-conserving product are the social development problem demanding prompt solutions.Along with the development of science and technology energy-conserving product also in continuous appearance, but these products are mainly to the low-voltage direct trend development.So both improved power consumption efficiency, energy savings has improved the security and the reliability of electricity consumption again.
Summary of the invention
In order to improve the utilization ratio of solar energy power generating, solve problem and energy-conservation development trend that above-mentioned employing inversion transformation technique exists, the utility model provides the solar photovoltaic powered low-voltage direct illuminator of a kind of efficient non-inversion.
The technical scheme that its technical problem that solves the utility model adopts is: solar photovoltaic assembly electric power output line links to each other with the power input end of master control set; the low-voltage DC of solar photovoltaic assembly generation is through master control set control by day; need not pass through the inversion conversion; directly to charge in batteries; master control set has rectification module; fill; the discharge prevention module; light-operated module; rectification module is adjusted solar photovoltaic assembly and is sent electric power; with stable electric current to charge in batteries; when battery tension is raised near the upper voltage limit of setting; controller is adjusted charging current; to charge in batteries, controller stops to charge in batteries when battery tension surpasses the upper voltage limit of setting, to prevent over-charging of battery with less current; when battery discharging is prescribed a time limit to the following of setting voltage; controller stops discharge, automatically switches to by the civil power power supply, and civil power electric power is powered to the LED illuminating lamp in the low-voltage direct mode.The load output port of controller links to each other with the LED illuminating lamp, and the power output end of controller and battery connect, when night LED illuminating lamp work, by controller control the electric power of battery do not need inversion directly with the low-voltage direct form to powering for the LED illuminating lamp.The voltage signal of light-operated module Direct Sampling solar photovoltaic assembly surpasses the threshold voltage of setting as the voltage of solar photovoltaic assembly, is identified as daytime, and master control set disconnects LED lighting control loop, to charge in batteries.The load output of master control set links to each other with low-voltage direct LED illuminating lamp, and the power output end of master control set and battery connect, and when low-voltage direct LED illuminating lamp is worked, exports low-voltage direct electric power by controller to load.Controller can be judged day and night automatically and accumulator cell charging and discharging is protected.
The beneficial effects of the utility model:
1, owing to adopted non-inversion transformation technique to reduce electric cost, improved the service efficiency of photovoltaic generation.
2, owing to adopted civil power networking low-voltage power supply, improved the reliability and the security of system's electricity consumption
3, adopt high brightness LED lighting lamp as Low voltage lamp, can save electric energy 50%--60%, can prolong the service life of lamp simultaneously greatly, greatly saves energy.
4, owing to adopted battery accumulation of energy function, under the mains failure situation, system still can normally move, and improves reliability of system operation greatly.
Owing to adopted technique scheme, the utility model is real to have solved the restriction condition of solar energy power generating thereby make, and has showed the high efficiency of transferring electric power, and the high efficiency of the high efficiency of unsteady flow and the high efficiency of battery applications and electrical appliance is beneficial to and applies.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model structure chart;
Solar photovoltaic assembly 1, high brightness LED lighting lamp 2, battery 3, controller 4, line 5.
The specific embodiment
Referring to Fig. 1, this usefulness is novel comprising in fact: solar photovoltaic assembly 1, high brightness LED lighting lamp 2, battery 3, controller 4, line 5.When had sunlight daytime, solar photovoltaic assembly 1 produced voltage during enforcement, was linked to each other with the power input end mouth of controller 4 by lead, and controller 4 these voltages of sampling disconnect LED lighting loop, to reduce the circuit in-fighting of LED illuminating lamp 2, save electric energy.At this moment solar photovoltaic assembly 1 is transported to battery 3 after producing 4 controls of electric power via controller, and accumulators 3 chargings are when battery is full of; when being the battery overvoltage; at this moment controller 4 disconnections are connected with battery 3, stop charge in batteries, with the protection battery.Controller 4 can be discerned day and night automatically, there is not sunlight to controller 4 merging LED lighting loops when night, the load output port of controller 4 links to each other with the circuit of LED illuminating lamp 2, LED illuminating lamp 2 usefulness sound or light-operated triggering, when the sound LED illuminating lamp 2 triggered by acoustic control or unglazed according to the time, the power supply output fracture of the electric power via controller 4 of battery 3 directly flows to LED illuminating lamp 2 with the low-voltage direct standard, makes the illumination of LED illuminating lamp, postpones to extinguish automatically after a period of time.When battery 3 is under-voltage; controller 4 will automatically shut down the output port of power source of battery 3, and with protection battery 3, the power input end mouth of controller 4 is transformed into the line 5 behind step-down rectifier automatically simultaneously; to the power supply of LED illuminating lamp, guarantee the stable operation of whole system by civil power.
