Description
Technical field
The utility model relates to a kind of solar LED light fixture system, more specifically to a kind of solar LED light fixture energy saving of system circuit.
Background technology
Existing common solar LED light fixture system when running into cloudy day long period, just can't normally use, because the solar energy at cloudy day is less, therefore can't be transformed into enough electric energy, the solar LED light fixture can't operate, the time of perhaps working is short, can't satisfy the demand of normal use.Existing solar LED light fixture system normally solves by the power that increases the solar recharging part, but has increased cost so greatly, and because storage battery is in improper charging and discharging state, storage battery is had bad influence, so effect is bad.
Summary of the invention
The purpose of this utility model provides a kind of solar LED light fixture energy saving of system circuit, can effectively reduce energy consumption, prolongs the time of using, and the technical scheme of employing is as follows:
Solar LED light fixture energy saving of system circuit of the present utility model comprises LED, it is characterized in that: also comprise oscillating circuit, described oscillating circuit comprises inductance, first electric capacity, second electric capacity, biasing resistor, accent leakage resistance, NPN triode and PNP triode; The anodal connecting circuit positive pole of LED, the negative pole of LED connects the inductance positive pole, inductance negative pole connecting circuit negative pole, the second electric capacity two ends are the connecting circuit positive and negative electrode respectively; The emitter connecting circuit positive pole of NPN triode, its collector electrode connects the LED negative pole, its base stage connects the collector electrode of PNP triode, the emitter connecting circuit negative pole of PNP triode, the base stage of PNP triode connect transfers leakage resistance, transfers leakage resistance connecting circuit positive pole, the anodal connecting circuit positive pole of biasing resistor, negative pole connects the base stage of NPN triode, and first capacitance cathode connects the base stage of PNP triode, and negative pole connects the inductance positive pole.
Owing to adopted oscillating circuit, so LED glimmers fast, because flicker is rapid, so people's eyes can not discover, and the operating time of LED can prolong similar one times, therefore can effectively reduce energy consumption, prolongs the time of using.
The utility model beneficial effect against existing technologies is owing to be provided with energy-saving circuit, therefore can effectively reduce energy consumption, prolong the time of using, even make the solar LED light fixture run into cloudy day time, also can normally use, simple in structure, be easy to realize, cost is low, effective.
