Description
Technical field
The present invention relates to street lighting technical field, is specifically that one kind carries stand-by power supply solar LED street lamp.
Background technology
Traditional solar street light typically uses pregnant solution type lead acid accumulator separately as energy-storage travelling wave tube, and using simple
Two-stage charge control mode；Using low-pressure sodium lamp or electricity-saving lamp etc. as illumination lamp source.It fact proved, traditional sun
Energy streetlight illumination there is it is more the shortcomings that：(1) lamp source service life is shorter.Be present more shortcoming in traditional lighting lamp source, such as save
Can lamp, general power is smaller, and service life about 2000 hours；And even if low-pressure sodium lamp light efficiency is higher, but because its work electricity
Pressure it is still higher, if applied in solar power system, generally require inverter, this by improve system cost.(2) it is rich
Liquid formula lead-acid accumulator premature failure.Because pregnant solution type lead acid accumulator design service life is shorter, charge and discharge cycles number is very
Hardly possible adds the maintenance cost of system more than 2000 times.(3) dim light charging ability deficiency.The operating voltage one of lead-acid accumulator
As be higher than a certain threshold value, such as the lead-acid accumulator that rated voltage is 12V, during its normal work, voltage is typically in 10.8-
14.7V ranges, and under low light condition, solar cell terminal voltage likely to be less than lead-acid accumulator voltage, at this moment too
Energy after positive energy cell photoelectric conversion can not be exported to battery, but is directly internally absorbed as heat energy, and this is anti-
Come over to make solar panels premature aging to fail, reduce solar cell service life；Conversely, when illumination is strong, solar energy
Battery terminal voltage significantly rises to about 20V, the maximum charging voltage allowed higher than lead-acid accumulator, if directly stored to plumbic acid
Battery is charged, it will damage lead-acid accumulator.
Ultracapacitor is a kind of energy storage device of novel high-power density, has many lead-acid accumulators incomparable
Advantage, but higher in view of current super capacitor price, is used alone that ultracapacitor is larger as energy storage device cost and nothing
Method meets system stored energy requirement, and battery, which is used alone, can not meet the requirement of larger pulsating power output, and battery makes
It is shorter with the life-span.Therefore in reality in use, being used as the accumulator of system by the use of lead-acid accumulator and ultracapacitor mixing
The respective advantage of part, combining super capacitor device high power density and the big energy density of lead-acid accumulator, it is technical according to both
Complementarity, the novel energy-storing element based on ultracapacitor and lead-acid accumulator hybrid energy-storing is formed, utilizes ultracapacitor
Good characteristic optimizes the charge and discharge process of lead-acid accumulator, it is possible to reduce charge and discharge cycles number, increasing storage battery service life,
Improve energy storage efficiency.In addition, it is unstable due to solar energy, cause existing LED street lamp often to light unstable, because
And it have impact on use.
The content of the invention
The shortcomings that in order to overcome above-mentioned prior art, the present invention provide one kind and carry stand-by power supply solar LED street lamp, have
There are solar cell maximal power tracing (MPPT) and dim light charge function, energy storage efficiency is improved, for the temperature of lead-acid accumulator
Characteristic is spent, using technique for temperature compensation, realizes the accurate control of charging voltage, and is ensured using stable.
The present invention is realized with following technical scheme：One kind carries stand-by power supply solar LED street lamp, including with the sun
The ultracapacitor group of energy cell panel connection, with the step-down/up type DC/DC change-over circuits being connected, is changed with step-down/up type DC/DC
The charging circuit of circuit connection, the lead-acid accumulator being connected with charging circuit, lead-acid accumulator is by LED drive circuit to LED
Street lamp power supply, road lamp power supply, solar voltage is connected with turn with step-down/up type DC/DC change-over circuits in solar panel and lead-acid accumulator
Sample circuit and DC/DC transducer drive circuits., in addition to stand-by power supply, described stand-by power supply and charging circuit electric signal
Connection, described stand-by power supply is connected to obtain with charging circuit also add voltage-stablizer on circuit, described voltage-stablizer is numerical control
Voltage-stablizer, and transmit signals to distal end.
The beneficial effects of the invention are as follows：Using ultracapacitor group and the structure of lead-acid accumulator hybrid energy-storing, solar energy
The solar energy of array output is excellent using ultracapacitor group and step-down/up type DC/DC converters first through ultracapacitor group
Change lead-acid accumulator charge and discharge process, realize the charging of battery under low light condition.On this basis, in addition to stand-by power supply,
Described stand-by power supply is connected with charging circuit electric signal, and described stand-by power supply is connected to obtain on circuit with charging circuit also to be increased
Voltage-stablizer is added, described voltage-stablizer is digital control voltage stabilizer, and transmits signals to distal end, and above-mentioned design both ensure that overall
Practicality, while ensure that voltage stabilizing when entirety uses, it is ensured that the physical life of LED.
