Description
Technical field
The utility model relates to Application of Solar Energy field, particularly a kind of Led street lamp that utilizes solar lighting.
Background technology
Solar street light be take sunshine as energy sources, daytime solar energy photovoltaic panel by absorbing sunshine, realize opto-electronic conversion, charge a battery, evening battery to street lamp power supply, road lamp power supply, energy-saving safe is pollution-free.But also have defect, first the photoelectric transformation efficiency of solar street light photovoltaic panel is lower, general efficiency only has 12%-15%, therefore solar energy often occurs, particularly run into when overcast and rainy, the situation that battery electric quantity is inadequate often occurs, exist the out-of-work risk of Led occurs.By increasing the area of solar energy photovoltaic panel, may be able to address this problem, and the cost of solar energy photovoltaic panel is higher, and in a lot of occasions and be not suitable for increasing the area of solar energy photovoltaic panel.
Summary of the invention
Technical problem to be solved in the utility model is how not increasing the utilization ratio that improves solar energy in the area situation of solar energy photovoltaic panel, for Led street lamp provides sufficient electric weight.
In order to solve the problems of the technologies described above, the utility model has designed a kind of solar energy Led street lamp, comprise lamp stand, solar energy photovoltaic panel, battery, controller and Led lamp, described solar energy photovoltaic panel is connected with battery, described battery is connected with Led lamp with controller, characterized by further comprising insulation water storage box, heat collector, temperature-difference circulation pump, described heat collector is arranged on lamp stand near the peripheral surrounding on top, it is inner near position, top that described insulation water storage box is arranged on lamp stand, insulation water storage box is communicated with heat collector by upper circular tube, temperature-difference circulation pump one end communicates with insulation water storage box, the other end is communicated with heat collector by lower circulation pipe, also comprise thermoelectric cell, thermal conductive metal plate, described thermal conductive metal plate is close to insulation water storage box, and the high temperature face of described thermoelectric cell is close to thermal conductive metal plate, and described thermoelectric cell is connected with battery.
Enforcement the utlity model has following beneficial effect: because current photo-thermal conversion efficiency is higher, by increasing apparatus for heating water by solar energy and thermoelectric cell, the final object that increases photoelectric transformation efficiency that realizes, can realize whole day and all may realize the object to charge in batteries, for illumination, Led provides sufficient power supply.
Accompanying drawing explanation
Fig. 1 is the structural representation of solar energy Led street lamp.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 is the structural representation of solar energy Led street lamp, solar energy Led street lamp comprises lamp stand 7, solar energy photovoltaic panel 1, battery, controller 5, Led lamp 3, insulation water storage box 2, heat collector 6 and temperature-difference circulation pump, battery is arranged on lamp stand 7 inside, solar energy photovoltaic panel 1 is connected with battery, battery is connected with Led lamp 3 with controller 5, battery and controller 5 integral body are done waterproof sealing, heat collector 6 is arranged on lamp stand 7 uniformly near the peripheral surrounding on top, it is inner near position, top that insulation water storage box 2 is arranged on lamp stand 7, insulation water storage box 2 is communicated with heat collector 6 by upper circular tube, temperature-difference circulation pump one end communicates with insulation water storage box 2, the other end is communicated with heat collector 6 by lower circulation pipe.The charging operation principle of 1 pair of battery of solar energy photovoltaic panel is with the operation principle of current existing solar energy Led street lamp.
Insulation water storage box 2, heat collector 6 and temperature-difference circulation pump are realized the function of regular solar water heater, most effective due to what in current Application of Solar Energy, photo-thermal was changed, therefore increase after the device of solar water heater, realize when having the sun by day, realize fast photo-thermal conversion, solar energy is converted into the thermal energy storage in insulation water storage box 2.By increasing thermoelectric cell, thermal conductive metal plate 4, described thermal conductive metal plate 4 is close to insulation water storage box, with hot water equality of temperature in insulation water storage box 2, the high temperature face of thermoelectric cell is close to thermal conductive metal plate 4, in insulation water storage box 2, hot water reaches uniform temperature, be that the high temperature face of thermoelectric cell and the temperature difference of low temperature face reach certain difference, thermoelectric cell starts to carry out thermoelectricity conversion, and thermoelectric cell and battery charge.Even when exterior light illumination very weak or night, outside solar energy photovoltaic panel 1 and heat collector 6 have stopped photoelectricity and photo-thermal conversion, as long as the hot water in insulation water storage box 2 also reaches certain temperature, thermoelectric cell just can also continue battery to charge.Substantially realize whole day and all may realize the object to charge in batteries, arrived the object that sufficient power supply is provided for illumination Led.
Above disclosed is only a kind of embodiment of the utility model, certainly can not limit with this interest field of the utility model, one of ordinary skill in the art will appreciate that all or part of flow process that realizes above-described embodiment, and the equivalent variations of doing according to the utility model claim, still belong to the scope that utility model contains.
