Specific implementation mode
Embodiment one
For the present embodiment as shown in Fig. 2, on solar LED street lamp, the solar LED street lamp includes being sequentially connected in series shape
At the power supply of access, photosensitive sensor 1 and LED light 2,
The fault-proof circuit includes protection circuit and warning circuit；
The protection circuit includes contactor KM1 3, and the contactor KM1 3 includes normally opened contact 1 and coil one
32；
The coil 1 is connected in parallel between the photosensitive sensor 1 and LED light 2, and the normally opened contact 1 is connected in parallel on
The both ends of the photosensitive sensor 1；
The warning circuit is connected on the protection circuit.
When 1 fault-free of photosensitive sensor, daytime, photosensitive sensor 1 receives illumination, and resistance value is infinitely great, entire circuit
In open-circuit condition, coil KM1 must not electricity；When night, the resistance value of photosensitive sensor 1 is substantially equal to 0, and entire circuit is led
Logical, the both ends of photosensitive sensor 1 are without pressure drop at this time so that KM1 coils must not be electric, and one 31 attonity of normally opened contact is still within
Normally open.So LED light 2 is controlled by photosensitive sensor 1, LED light is extinguished for 2 daytime, and night opens.
When 1 failure of photosensitive sensor（Breakdown）When, photosensitive sensor 1 is equivalent to an equivalent resistance, and the two of coil 1
End forms pressure difference, obtains electric, and normally opened contact 1 is closed, and LED light 2 is always on；Testing staff can be according to the LED light being always on daytime
2 find the failure of photosensitive sensor 1, safeguard in time.
The warning circuit includes buzzer, and the buzzer is serially connected in the side of the normally opened contact 1.When normally opened
One is got an electric shock when being closed, buzzer obtains electric, sends out alarm.
Photosensitive sensor in this case is weak using incident light, and resistance reduces, incident intensity, the increased photosensitive electricity of resistance
Resistance.
