Abstract
The utility model relates to a solar energy lamp with a luminous diode, which comprises a charging circuit and a discharging circuit, wherein, a luminous component in the discharging circuit is a luminous diode; after the luminous diode is connected with an inductor in parallel, the luminous diode is connected with the collecting electrode of a triode; the base electrode of the triode is connected with the output end of an oscillator; the input end of the oscillator is connected with a common point of a resistor and a photoresistor; the charging circuit is across connected with a rechargeable battery and a switch by a solar energy battery assembly through backflow-proof diode. The oscillator can be trigger to work and to lighten the luminous diode or not to lighten the luminous diode according to the resistance value of the photoresistor. Because of the high luminous efficiency of the luminous diode, only one 1.2v rechargeable battery is needed, and correspondingly the areas of the solar energy battery are reduced to make the cost of the utility model is greatly reduced.
Description
The utility model relates to a kind of solar illumination apparatus.
Solar lamp is a kind of pollution-free green energy products, and it is to utilize solar cell independently-powered, needn't install electric wiring or bury underground cable, and is easy for installation, and surrounding environment without any influence, is not just needed other power supplys and cost of use once installing.And the luminescent device of the Solar lamp of current trend generally is incandescent lamp or fluorescent tube, because their luminous efficiency is lower, life-span is shorter, in order to obtain better illumination effect and long lighting hours, need rechargeable battery with larger area solar cell and larger capacity, and the two present price is relatively expensive, and the cost of Solar lamp is improved, and has therefore influenced their popularization and use.
The purpose of this utility model is: design a kind of light-emitting diode Solar lamp that adopts light-emitting diode as luminescent device, can solve the above problem that exists.
For achieving the above object, the technical solution adopted in the utility model is: it comprises charging circuit and discharge circuit.Luminescent device in the discharge circuit is a light-emitting diode, after being in parallel, it and inductance insert the collector electrode of triode, the base stage of triode is connected with the output of oscillator, the input of oscillator is received the common point of being made up of resistance and photo resistance, charging circuit is by solar module, behind the anti-backflow diode, jump on rechargeable battery and the switch.Rechargeable battery is a power supply that rated voltage is 1.2V.
The utility model is compared with background technology, the useful effect that has is: adopt the luminescent device of light-emitting diode as Solar lamp, because the luminous efficiency height of light-emitting diode, only need a 1.2V rechargeable battery to make power supply, the corresponding solar cell area reduces greatly, and the cost of Solar lamp is descended significantly.The utility model is highly suitable for garden, the usefulness of road lighting and decoration.
The utility model will be further described below in conjunction with accompanying drawing.
Accompanying drawing: circuit theory diagrams of the present utility model.
As shown in drawings, connect switch 8, circuit is in running order.The voltage divider that constitutes by photo resistance 2 and resistance 1, by day, ambient light illumination is big, the resistance value of photo resistance 2 is little, and the branch in the photo resistance 2 forces down, and the input level of oscillator 3 is on the low side can not work, also just not output, triode 4 ends, and solar module 10 becomes electric energy with solar energy converting under illumination, by 7 chargings of 9 pairs of rechargeable batteries of anti-backflow diode.In night, ambient light illumination diminishes, when the resistance of photo resistance 2 increases to certain value, high-frequency pulse signal is exported in oscillator 3 work that is triggered, when being output as high level, and triode 4 conductings, rechargeable battery is by inductance 5, and triode 4 and switch 8 constitute path, flow through electric current and stored magnetic energy in the inductance 5; When oscillator 3 was output as low level, triode 4 ended, and the magnetic energy in the inductance 5 discharges, and electric current flows through light-emitting diode 6, and light-emitting diode 6 is lighted.During the next high level of oscillator 3 output, triode 4 conducting again, inductance 5 flows through electric current and stored magnetic energy again; During the next low level of oscillator 3 output, triode 4 ends again, and the magnetic energy in the inductance 5 discharges, and light-emitting diode 6 is lighted again, so goes round and begins again, and light-emitting diode 6 just can be worked under the power supply that has only 1 1.2V rechargeable battery 7.
