The utility model discloses an LED street lamp using solar energy which is long in service lifetime, large in battery power, fast in charging speed, and free of pollution. The LED street lamp comprises a lamp stand, an LED lamp holder, a solar battery assembly, a controller and a storage battery. The storage battery is composed of a DC booster and a capacitor. An input end of the DC booster is connected to the solar battery assembly, and an output end of the DC booster is connected to the capacitor. An output end of the capacitor is connected to the LED lamp holder. The LED street lamp using solar energy is advantageous in that a super capacitor with large capacity is adopted, and thereby the charging speed of the super capacitor is fast, the discharging capability of heavy current is super strong, and energy conversion efficiency is high; endurance time of an LED street lamp using solar energy is increased; the LED street lamp can be well used even in continuous cloudy or rainy days, and in winter when illumination is insufficient, and normal road condition can be ensured.
Description
Technical field
The utility model relates to a kind of lighting device, is specifically related to a kind of solar LED street lamp.
Background technology
Many solar street lights are arranged at present on the market, and it is made up of several parts such as solar module part (comprising support), LED lamp holder, solar lamp controller, battery (comprising battery warmer) and lamp stands.The solar street light battery is the application of battery in solar street light, and the effect of solar street light battery is the electrical power storage that solar module is produced, and for the LED lamp holder energy is provided when the illumination deficiency or when throwing light on evening.The solar street light battery that adopts at present is commonly used has sealed lead acid storage battery, common lead acid accumulator, colloid storage battery, lithium iron battery and alkaline nickel cadmium accumulator etc.; These battery cycle charge-discharge number of times are more than enough; Self-discharge rate is low, and long service life is with few maintenance or non-maintaining.But the electric weight of these batteries still can't meet the demands fully, especially in continuously overcast and rainy and illumination in winter not enough period, can not satisfy the normal illumination needs especially.
Summary of the invention
In order to overcome the deficiency of prior art, the utility model provides a kind of long service life, accumulator electric-quantity is big, charging rate is fast, the solar LED street lamp of pollution-free environmental protection.
The utility model solves the technical scheme that its technical problem adopted:
A kind of solar LED street lamp; Comprise lamp stand, LED lamp holder, solar module, controller and battery; Said battery is made up of DC booster and capacitor; The input of DC booster is connected with solar module, and the output of DC booster is connected with capacitor, and the output of capacitor is connected with the LED lamp holder.
In the utility model, said DC booster comprises that inverter I, stepup transformer and rectifier I form.
In the utility model, be provided with the DC decompression device between said capacitor and the LED lamp holder.
In the utility model, said DC decompression device comprises that inverter II, reducing transformer and rectifier II form.
The beneficial effect of the utility model is: the battery of the utility model has adopted jumbo super capacitor; This super capacitor charging rate is fast, large current discharging capability is superpower, energy conversion efficiency is high; Not only increased the cruising time of solar LED street lamp; Even in continuously overcast and rainy and illumination in winter not enough period, also can use well, guarantee normal pavement behavior.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of present embodiment.
The specific embodiment
With reference to Fig. 1; The utility model provides a kind of long service life, accumulator electric-quantity is big, charging rate is fast, the solar LED street lamp of pollution-free environmental protection; Comprise lamp stand, LED lamp holder 1, solar module 2, controller 3 and battery 4, said battery 4 is made up of DC booster 41 and capacitor 42, and the input of DC booster 41 is connected with solar module 2; The output of DC booster 41 is connected with capacitor 42, and the output of capacitor 42 is connected with LED lamp holder 1.
As preferred embodiment; Said DC booster 41 comprises that inverter I411, stepup transformer 412 and rectifier I413 form; Inverter I411 changes the 12V DC current that solar module 2 sends into alternating current; Alternating current boosts through stepup transformer 412 again, and the alternating current after will boosting through rectifier I413 then is converted into HVDC.HVDC directly charges to capacitor 42.Corresponding for the voltage that the output voltage that makes capacitor 42 and LED lamp holder 1 are required, be provided with DC decompression device 5 between capacitor 42 and the LED lamp holder 1.Said DC decompression device 5 comprises that inverter II51, reducing transformer 52 and rectifier II53 form; Capacitor 42 after the charging is emitted high voltage direct current; High voltage direct current transfers High Level AC Voltage to behind inverter II51; High Level AC Voltage is integrated into low-voltage DC through reducing transformer 52 with rectifier II53 again, thereby satisfies the required voltage of LED lamp holder 1.
The battery 4 of the utility model has adopted jumbo ultracapacitor 42; These ultracapacitor 42 charging rates are fast, large current discharging capability is superpower, energy conversion efficiency is high; Not only increased the cruising time of solar LED street lamp; Even in continuously overcast and rainy and illumination in winter not enough period, also can use well, guarantee normal pavement behavior.
