SUMMERY OF THE UTILITY MODEL

The utility model discloses to exactly be to above-mentioned problem, provide a leak protection water and electrocute L ED lamps and lanterns automatic control device circuit, this automatic control device circuit mainly adopts signal probe detection lamp body whether intake, and the signal of intaking does not have the power in the comparator processing output control signal cut-off power guarantee lamps and lanterns, makes lamps and lanterns safe and reliable.

In order to achieve the technical purpose, the utility model discloses a leak protection water electrocution L ED lamps and lanterns automatic control device circuit, including the main circuit that has silicon controlled rectifier T to and AC input module, step-down rectifier module, filtering voltage stabilizing module, signal probe, signal processing module, control output module, L ED load of being connected for electricity in proper order with the main circuit.

As an improvement of the utility model, all be equipped with waterproof rubber coating layer on AC input module 1, step-down rectifier module 2, filtering voltage stabilizing module 3 and signal processing module 5, the control output module 6.

As a further improvement of the present invention, the signal probe 4 is partially exposed outside the whole circuit structure.

The utility model discloses mainly be behind the signal probe detects the signal of intaking, feed back to signal processing module and carry out signal processing, signal probe is anhydrous is that the high level obtains high level signal processing output high level control signal, this control signal makes the opto-coupler input switch on and opens silicon controlled rectifier T by opto-coupler output again, L ED load is gained the electricity and is lighted, if signal probe has water to be low level signal processing output low level control signal, this control signal makes the opto-coupler input turn-off by opto-coupler output silicon controlled rectifier T turn-off L ED load lose the electricity and extinguish.

After the circuit structure is adopted, the utility model has the advantages of as follows:

1. the circuit structure of the utility model can lead the lamp to have water leakage phenomenon, and the control system automatically cuts off the input of the load, thus leading the lamp to automatically realize the anti-leakage and electric shock phenomena;

2. the circuit structure of the utility model can eliminate the water leakage phenomenon in the lamp and automatically recover the normal work of the lamp after drying without damaging the lamp;

3. the whole control system of the utility model adopts an integrated design, is simple, convenient and reliable to use, and has lower manufacturing cost;

4. the utility model discloses a controlling means circuit can satisfy the illumination lamps and lanterns in each illumination places such as highway, tunnel, parking area, courtyard, corridor, advertisement.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments, and in order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to specific embodiments.

Example one

The operating principle of the first embodiment is as shown in fig. 1, after AC input mains voltage is reduced by resistance-capacitance, the AC input mains voltage is rectified by D1 to obtain a dc power supply, a voltage regulator tube D2 and a capacitor C2 are stabilized at 12V to supply to a comparator U1, a signal probe 4 is a 10R (1M) resistor and is exposed outside the whole system, and the dc power supply has the advantages of being used for detecting whether water is introduced or not, when the probe 4 detects that water is absent, the 1M and R3(100K) are connected in parallel to obtain a 91K resistance value, if R2 takes 68K, a comparator U1+ end is 12 × 91/(68+91) 6.868V, a comparator-end R4 and R5 are equal to take 24K, the 6V as a reference voltage, at this time, the + end 6.868V is greater than the 6V reference voltage, the comparator output is a high level Q1 is turned on, the input of U2 is turned on to turn on the power conduction output, and turn on the thyristor ED load T, and at this time L ED light is turned.

When the probe 4 detects that water exists, the + terminal voltage of the comparator is no longer 6.868V, and the resistance value of the water is actually measured to be about 10 to 20, so that the probe R10(1M) is connected with the water resistor (20K) and the R3 in parallel to obtain 16.39K, at this time, the + terminal voltage of the comparator is 12 × 16.39/(68+16.39) ═ 2.33V, the voltage is lower than the reference voltage 6V, the output of the comparator is low level Q1 is turned off, the input of the optical coupler U2 is turned off, the output of the optical coupler U2 is turned off, the thyristor T is turned off, and at this time, the L ED load power.
