Abstract
The utility model relates to a solar yard lamp which comprises a solar power module, an energy storage module and an LED lighting module. The solar power module comprises a photovoltaic module and a photovoltaic controller. The photovoltaic module is connected with the photovoltaic controller. The energy storage module comprises a super-capacitor module and a battery energy storage module. The power of the LED lighting module is supplied by the battery energy storage module. The photovoltaic module charges the super-capacitor module under the control of the photovoltaic controller. The super-capacitor module charges the battery energy storage module. The solar yard lamp absorbs weak and unstable solar energy which can not be absorbed by a battery in the morning or at night or on an overcast and rainy day or the like by utilizing the characteristic that a super-capacitor can absorb weak currents, so that more electric energy is maintained in a storage battery, and the service life of the battery is prolonged.
Description
Technical field
The utility model relates to a kind of illuminator, particularly a kind of solar energy garden lamp.
Background technology
Solar energy garden lamp due to cheap, without additionally connecting up, install simple advantage, by increasing consumer, adopted, but there is the shortcomings such as fault rate is high, brightness is low, the life-span is short in solar energy garden lamp at present, certainly will affect the confidence that consumer uses solar energy garden lamp, be unfavorable for the sound development of industry.According to investigations, most consumers express willingness, and to accept price high by 30%, but solar energy garden lamp stable and that the life-span is long.
Solar energy garden lamp brightness is at present low, it is due to the illumination deficiency in the situation that life-span is short, the electric current that photovoltaic module produces is too small, be not enough to charge in batteries, cause generated energy not enough, in order to guarantee the working time, can only adopt low-power LED lamp, and charging current is unstable in this case, accelerated the aging of battery, shortened the life of storage battery.
Summary of the invention
The purpose of this utility model is in order to overcome the defect of above-mentioned background technology, and a kind of solar energy garden lamp is provided.
A solar energy garden lamp, it comprises solar-electricity source module, energy-storage module and LED lighting module.Described solar-electricity source module comprises photovoltaic module and photovoltaic controller, and described photovoltaic module is connected with photovoltaic controller.Described energy-storage module comprises super-capacitor module and battery energy storage module, described LED lighting module is by described battery energy storage module for power supply, described photovoltaic module is described super-capacitor module charging under the control of photovoltaic controller, and described super-capacitor module is described battery energy storage module charging.
By above-mentioned solar energy garden lamp, described super-capacitor module comprises at least one super capacitor, and when comprising two and above super capacitor, the plurality of super capacitor is connected in parallel.
By above-mentioned solar energy garden lamp, described battery energy storage module comprises and charges and discharge controller and battery; Described battery is connected with LED lighting module with super-capacitor module by the described controller that charges and discharge.
Preferably, described battery can be lead-acid accumulator.
By using super-capacitor module, be combined and be applied to solar power supply unit with battery, utilize the energy storage characteristic of super-capacitor module physical process and it to have natural application advantage with the solar energy that is combined in of battery, make the utility model can absorb night morning, the nonabsorbable small and weak unsettled solar energy of battery such as overcast and rainy.Thereby allow in battery, keep more electric energy, the characteristic maintaining from battery life, protected battery, extend the service life of battery, strengthened the stability of whole solar energy system, reached the object of energy-conserving and environment-protective.
Accompanying drawing explanation
Fig. 1 is the structure principle chart of solar energy garden lamp in the utility model one embodiment.
The specific embodiment
In order to allow those skilled in the art more understand the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is further described.
Solar energy garden lamp of the present utility model wherein an example structure principle as shown in Figure 1, this solar energy garden lamp comprises solar-electricity source module 1, energy-storage module 2 and LED lighting module 3.
Described energy-storage module 2 comprises super-capacitor module 21, charges and discharge controller 22 and lead-acid accumulator 23, by described, charge and discharge controller 22 and described lead-acid accumulator 23 forms battery energy storage module, described lead-acid accumulator 23 is connected with super-capacitor module 21, described LED lighting module 3 by the described controller 22 that charges and discharge, and realizes the function of charging and discharging.
Described solar-electricity source module 1 comprises photovoltaic module 11 and photovoltaic controller 12, and described photovoltaic module 11 is connected with described super-capacitor module 21 by described photovoltaic controller 12.Described photovoltaic module 11 is converted into electric energy by the solar energy receiving, and by described photovoltaic controller 12, charges to described super-capacitor module 21.Super-capacitor module can comprise at least one super capacitor, when comprising two and above super capacitor, and the plurality of super capacitor composition super-capacitor module that is connected in parallel.
When described super-capacitor module 21 is charged to certain voltage, described in exciting, described super-capacitor module 21 charges and discharge the charging module of controller 22.Now, described super-capacitor module 21 is charged the voltage with stable to described lead-acid accumulator 23.Because described super-capacitor module 21 can absorb very faint electric current, so still can charge to described super-capacitor module 21 in the insufficient situation of sunlight, Deng electric weight, be accumulated to a certain degree, can charge to described lead-acid accumulator 23 again, thereby can make full use of solar energy, allow described lead-acid accumulator 23 keep more electric energy, extend the life of a cell, and then extend the life-span of solar energy garden lamp.
When night, 22 of described charging-discharging controllers are controlled described lead-acid accumulator 23 and are discharged, thereby make 3 work of LED lighting module.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from the utility model aim, make various variations.
