For achieving the above object, a kind of solar alarming device of the utility model is made up of power supply, intermittent oscillation circuit and light-emitting device, and wherein, described power supply is powered to intermittent oscillation circuit, and is luminous by the output control light-emitting device of intermittent oscillation circuit.At this, described power supply is an electrical storage device, and other is provided with a solar cell, and its output connects electrical storage device by charging circuit.

Above-mentioned charging circuit can be the additives for overcharge protection circuit; the output of above-mentioned electrical storage device also can be connected with the over circuit; the output of over circuit is given above-mentioned intermittent oscillation circuit power supply through voltage stabilizing circuit; the output of intermittent oscillation circuit connects constant-current drive circuit, and it is luminous to drive above-mentioned light-emitting device by constant-current drive circuit.

Above-mentioned charging circuit also can an alternating current-direct current charging circuit in parallel, and the alternating current-direct current charging circuit connects direct current or AC charger.

Wherein, described light-emitting device can be bulb, light-emitting diode or LED luminescent device etc.

Because above design, the utility model selects for use solar energy as the energy, utilizes electrical storage device to power to light-emitting device, and long service life has avoided changing the trouble of battery, and is energy-conservation, laborsaving, with low cost, and pollution-free, can be described as Green Product.In addition, substitute the sort of traffic and the pavement marker high cartridge type alarming device that scribbles reflectorized material commonly used, because the flicker action of the light-emitting device of its top design and improve its caution greatly and render a service is safe and practical with the utility model.Moreover the utility model has adopted measures such as voltage stabilizing, frequency stabilization and constant-current driving, makes performance of the present utility model more reliable and more stable.

Below in conjunction with drawings and the specific embodiments the utility model is done a detailed explanation again.

Ask for an interview Fig. 1, be the schematic appearance of the utility model solar alarming device, Fig. 2, the another kind of schematic appearance when being applied to traffic and pavement marker for the utility model.

See also Fig. 3, circuit block diagram of the present utility model, the utility model is made up of solar cell 1, electrical storage device 2, intermittent oscillation circuit 3 and light-emitting device 4, utilize solar cell 1 to give electrical storage device 2 chargings for electric energy transform light energy, as the power supply of intermittent oscillation circuit 3 and light-emitting device 4, by the flicker of intermittent oscillation circuit 3 control light-emitting devices 4.

See also Fig. 4, the circuit theory diagrams of the utility model one specific embodiment, by solar cell 1, electrical storage device 2, by triode T1, T2, resistance R 2, R3, intermittent oscillation circuit 3 that capacitor C 1 element such as grade is formed and light-emitting device 4 are formed, wherein, the light-emitting device 4 of present embodiment is bulb DD, provides power supply by solar cell 1 for electrical storage device 2 charging and for intermittent oscillation circuit 3.When the firm connection of power supply, resistance R 1, R6 provide very little base current Ib1 to T1, the T1 conducting, the collector current Ic1 after T1 amplifies again with the T2 conducting, amplifies back formation collector current Ic2 through T2 as the base current of T2, then the Vc2 current potential descends, by the coupling of capacitor C 1 and resistance R 2, cause the further increase of T1 base current again, form strong positive feedback, make the conducting of T2 pipe saturated, bulb DD is luminous.After charging capacitor C1 was full of electricity, the base current Ib1 of T1 reduced, and the base current Ib2 of T2 reduces, and the collector current Ic2 of T2 also reduces thereupon, and Vc2 rises, and Ib1 is further reduced, and forms positive feedback again, and the T2 pipe is ended, and bulb DD extinguishes.Charging capacitor C1 is by D1, DD, the discharge of R2 loop, and discharge off is got back to the state when rigidly connecting energize again, so bulb DD flicker is luminous.

The above-mentioned course of work is the process when the unglazed photograph of photosensitive tube D1, because D1 ends during unglazed the photograph, emitter junction to T1 does not have shunting action, D1 conducting when illumination, T1 ends, and circuit is in the state that T1, T2 end, and bulb DD does not work, can realize lighting flicker automatically night, and close daytime automatically.

See also Fig. 5 and Fig. 6; another embodiment of the present utility model; be made up of solar cell 1, additives for overcharge protection circuit 5, electrical storage device 2, over circuit 6, intermittent oscillation circuit 3, constant-current drive circuit 7 and light-emitting device 4 etc., the electrical storage device here is rechargeable battery E.
