Brief description of the drawings
Fig. 1 is structured flowchart of the present utility model;
Fig. 2 is a kind of schematic diagram of prior art;
Fig. 3 is schematic diagram of the present utility model.
Embodiment
The utility model is described in further detail with reference to embodiments.
A kind of existing solar LED Lawn lamp, brightness requirement is all than relatively low (being usually 3-4 lumens), the driving of use Circuit is also fairly simple (mono- inductance of a plug-in unit IC+), but efficiency is also relatively lower (being usually in 70-75% or so). As shown in Fig. 2 the driving chip (plug-in unit IC) commonly used using 1 batteries, periphery circuit element adds diode, electric capacity, resistance Etc. several elements so that power output is larger, efficiency is also improved a bit (75-80%).IC peripheral cells also compare many, in life Material cost is frequently present of during production higher, cost of labor is high, the not high aspect constraint of production efficiency.
A kind of high-power solar LED Lawn lamp, as shown in figure 1, including solar energy circuit, drive circuit, charging electricity Pond, boost inductance circuit and load.The utility model peripheral component is few, only needs an inductance, greatly reduces and be produced into Originally it is and artificial, it is easy to produce high efficiency:85~90% (representative values), can make full use of solar cell;Pass through adjustment of inductance electricity Stream, simple and convenient, electric current is stable, and uniformity is good;Input current is not influenceed by LED cut-in voltages;Low enable voltage, it is ensured that lamp Tool is just opened when ambient is dark enough;Enabling control has Schmidt's performance, it is ensured that steady when the bright blackout of light fixture is changed It is qualitative.
The output end of the solar energy circuit is connected with drive circuit;The output end of the drive circuit is electric with charging respectively Pond, boost inductance circuit and load connection;The output list of the rechargeable battery is connected with boost inductance circuit;The boost inductance The output end of circuit and load;The load is that switch S1 is provided with LED, LED, and switch S1 one end connects with rechargeable battery Earth polar is connected, and the other end is connected with LED earthing pole.As shown in figure 3, the drive circuit includes drive control device, driving control Device processed uses model JD1808 driving chip, and the driving chip of the JD1808 is encapsulated using COB.The boost inductance electricity Road includes inductance L1, and inductance L1 one end is connected with rechargeable battery positive pole, and neck one end is connected with load.
The solar energy circuit includes solar panels, mu balanced circuit and filter circuit, and the output end of the solar panels is passed through Mu balanced circuit and filter circuit are connected with drive circuit.By mu balanced circuit and filter circuit so that output electric energy more It is stable, influence will not be produced on rechargeable battery.The rechargeable battery output voltage is 1.2V battery.
Operation principle:
During daytime, the solar panels on solar energy circuit receive solar energy and are converted into electric energy, by driving chip to charging Battery charges, and power storage is converted light energy on rechargeable battery, while driving chip closes output loading automatically.Evening When, the electric energy of rechargeable battery release storage, driving chip automatically turns on output loading, is now lighting lamp state.
The electric energy that rechargeable battery provides for driving chip, the booster circuit being made up of driving chip and boost inductance, by original Carry out low-voltage battery and boost to output loading (LED) that the voltage lighted can be driven, now lamp is bright.So as to greatly improve electric energy Transformation efficiency.
