Background technology
Modern Traffic is busy especially, more and more many vehicle ' are arranged on road, therefore, various friendships are used to travelling of standard vehicle with livery, especially during night running, separate design between two-way, in the past just with white paint on the ground drawn area divide it, perhaps have the trapezoidal tapers first class mark of reflector central authorities' separation place setting, drive through out-of-date, must just have reflective effect and produce by the light of street lamp or car light.
Above-mentioned traditional night, road sign for remote area, did not for example have on the road of street lamp, was necessary to be provided with that have can luminous automatically road sign, yet these do not have the place of street lamp, often because electricity, so street lamp just is not set.Therefore, also has a kind of flash of light road sign that utilizes solar power generation traditionally, see also shown in Figure 1, equivalent circuit diagram for traditional solar energy road sign, it is to connect a charging circuit 200 by a solar receiver 100, when this solar receiver 100 receives solar energy, promptly to charging circuit 200 chargings.This charging circuit 200 series connection one switching circuit 300, therefore, if the solar energy deficiency time, this switching circuit 300 promptly forms path, links LED 1/LED2.Switching circuit 300 connect again one the vibration and output circuit 400, utilize the driving of triode Q1, make LED 1/LED2 can make one bright one flash of light of going out.Wherein, this charging circuit 200 also can connect a booster circuit 500, makes the voltage of supplying with light-emitting diode reach certain enough voltage.
Yet above-mentioned traditional flash of light road sign that utilizes solar power generation because its charging circuit generally is capacitor batteries or other rechargeable battery, also continues charging if surpass rated voltage, perhaps is lower than zero still continuous discharge of volt, the life-span that is easy to damage battery.
The utility model content
The purpose of this utility model is to solve the known problem that is easy to damage battery life of utilizing the flash of light road sign existence of solar power generation, and a kind of protective circuit of solar energy flashing road sign of energy extending battery life is provided.
The utility model includes a solar receiver and a charging circuit, the one end output of solar receiver is connected to charging circuit, other end ground connection, charging circuit can be rechargeable battery or capacitor batteries, it is characterized in that solar receiver is connected to an output additives for overcharge protection circuit in parallel of charging circuit; Solar receiver is connected to an output switching circuit in parallel of charging circuit, and charging circuit connects an over circuit, and a switching circuit vibration and an output circuit in parallel with the over circuit makes that several light-emitting diode sparklings are luminous.
In addition, the utility model also can have a road sign housing, and this road sign housing slightly is three-dimensional taper, and solar receiver is positioned at the last end face of road sign housing, and other circuit is arranged in the road sign housing, outside the side of light-emitting diode by the road sign housing visual it.
Advantage of the present utility model comprises: have additives for overcharge protection circuit and over circuit and have flash of light and reflective effect simultaneously to avoid rechargeable battery to damage, promote the life-span of rechargeable battery and reach.

Fig. 2 is an equivalent circuit diagram of the present utility model.
Fig. 3 is a circuit block diagram of the present utility model.
Embodiment
See also shown in Figure 2; be equivalent circuit diagram of the present utility model; it is the protective circuit with electronic component composition of charge and discharge function; it includes a solar receiver 100 and a charging circuit 200; the one end output of solar receiver 100 is connected to charging circuit 200, other end ground connection.Wherein, charging circuit 200 can be general rechargeable battery, also can be capacitor batteries (rated voltage is 2.3V).
See also Fig. 2, shown in Figure 3; solar receiver 100 is connected to an output additives for overcharge protection circuit 700 in parallel of charging circuit 200; can be for discharging and recharging; preferable; as shown in Figure 2; this additives for overcharge protection circuit 700 comprises a silicon reference diode U3 and a di-resistance R 9, R10, and a resistance R 10 serial connection ground connection wherein are to be used for discharge.
This solar receiver 100 is connected to an output switching circuit 300 in parallel of charging circuit 200, therefore, if when sunlight is arranged, 300 ground connection of this switching circuit (not conducting), solar receiver 100 can charge to charging circuit 200.And; when the output voltage (its maximum output voltage can reach 3.0V) of solar receiver 100 reaches one regularly (for example 2.35V); conduct current additives for overcharge protection circuit 700 then, and be unlikely to charging circuit 200 is charged constantly, to reach the function of protection.
And; this charging circuit 200 also connects an over circuit 800; 800 vibrations in parallel of switching circuit 300 and over circuit and output circuit 400 (for example utilizing microcontroller U2 control) make several LEDs 1, LED2 sparkling luminous.Wherein over circuit 800 comprises a triode Q3 and a di-resistance R 14, R15, and one of them resistance R 14 is connected with charging circuit 200, another resistance R 15 and triode Q3 ground connection in parallel.If when not having sunlight, 300 of switching circuits are the states of conducting, can connect a booster circuit 500, make the voltage of supplying with LED 1, LED2 reach certain enough voltage, and utilize the driving of triode Q1, make LED 1, LED2 can make one bright one flash of light of going out.When this switching circuit 300 state that is conductings, during charging circuit 200 discharges (current sinking), when dropping to certain voltage, in the time of for example between 0.55V～0.99V, then LED 1, LED2 can stop flicker, 200 of charging circuits are unlikely to overdischarge to 0 volt, therefore can avoid the infringement that causes because of overdischarge.
Therefore; according to above-mentioned equivalent circuit diagram; solar energy flashing road sign with protective circuit is to utilize a road sign housing (not shown); above-mentioned circuit is included within this road sign housing; this solar receiver 100 can be positioned at the last end face of road sign housing; and outside the side of those LEDs by the road sign housing visual it; and; the road sign housing can comprise that more several reflector (not shown) are positioned at the skew back face; make the utility model not only have flash of light and reflective function, have more long-life battery.
Advantage of the present utility model comprises: have additives for overcharge protection circuit and over circuit to keep away Exempt from the rechargeable battery damage, promote the life-span of rechargeable battery and reach to have simultaneously and glisten with reflective Effect.
