Abstract
The utility model discloses an LED refrigerator lighting system which comprises a charging circuit, a battery B, a switch G, a bridge rectifier, and an LED. The LED is used as the light source, and the LED has features of small volume, low working voltage, long service life, and better safeties for the users and the fire accidents; for ensuring the power supply for the LED, a voltage regulating and charging circuit is adopted for the LED refrigerator lighting system, and the battery, which is charged by the voltage regulating and charging circuit, can supply power for the LED; the switching process of the LED is realized by a magnetic strip control switch G on the refrigerator door seal. By the above structure, the utility model has advantages of non-contact, no contact points, no spark, long service life, small volume, high safety, and emergency functions of circuit breaking, etc.
Description
Technical field
The utility model belongs to lighting device, relates in particular to a kind of LED refrigerator illuminator.
Background technology
At present, the illuminator of refrigerator is made up of incandescent lamp and mechanical switch, and incandescent light fitting has that power consumption is big, heating is many, the life-span is short, volume is big, and there is spark, perishable the mechanical switch contact, and it is disconnected that the push rod of its exposed parts or briquetting easily bump, and influence the attractive in appearance of casing.The operating voltage of above-mentioned incandescent lamp is 220V, and its security is lower, can hurt our personal safety if the electric leakage situation takes place.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of simple in structure, and security is good, and is not fragile, a kind of LED refrigerator illuminator that the life-span is long.
The utility model is achieved through the following technical solutions:
A kind of LED refrigerator illuminator, it is by charging circuit, battery, switch and LED form, the positive terminal of LED links to each other with normally-closed contact 1 end of gauge tap G, the negative pole end of the negative pole end of LED and battery pack B, the continuous positive terminal of voltage-stabiliser tube W and the negative pole end of bridge rectifier link to each other, the positive terminal of battery pack links to each other with 3 ends of gauge tap G, gauge tap G normally opened contact 2 ends link to each other with the negative pole end of diode D5, the positive terminal of diode D5 links to each other with the negative pole end of voltage-stabiliser tube W and the positive terminal of bridge rectifier, and a N who exchanges the termination power lead-in wire of bridge rectifier holds, another of bridge rectifier exchanges terminating resistor R2, another termination capacitor C of resistance R 2, the L end of another termination power supply lead wire of capacitor C is parallel with resistance R 1 at the two ends of capacitor C.
Described switch G is a tongue tube.
The utility model has the advantages that: owing to adopted LED as light source in the utility model, and LED has characteristics such as volume is little, operating voltage is low, the life-span is long, and the person and fire had better security, in order to guarantee to provide power supply to LED, the utility model has adopted voltage stabilizing charging circuit, to battery charge, provide power supply by battery to LED by voltage stabilizing charging circuit again.The switch of LED is to be realized by the magnetic stripe gauge tap G that refrigerator doors is sealed up.Therefore, the utlity model has noncontact, contactless, no-spark, the life-span is long, volume is little, high safety, and have characteristics such as current failure emergency function.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model;
Fig. 2 is a structured flowchart of the present utility model.
The specific embodiment
Embodiment: LED refrigerator illuminator as shown in Figure 1, 2, it is made up of charging circuit, battery, switch G and LED, and described switch G is a tongue tube.The positive terminal of LED links to each other with normally-closed contact 1 end of gauge tap G, the negative pole end of the negative pole end of LED and battery pack B, the continuous positive terminal of voltage-stabiliser tube W and the negative pole end of bridge rectifier link to each other, the positive terminal of battery pack links to each other with 3 ends of gauge tap G, gauge tap G normally opened contact 2 ends link to each other with the negative pole end of diode D5, the positive terminal of diode D5 links to each other with the negative pole end of voltage-stabiliser tube W and the positive terminal of bridge rectifier, and a N who exchanges the termination power lead-in wire of bridge rectifier holds, another of bridge rectifier exchanges terminating resistor R2, another termination capacitor C of resistance R 2, the L end of another termination power supply lead wire of capacitor C is parallel with resistance R 1 at the two ends of capacitor C.
The course of work is as follows: when refrigerator doors is in closed condition, door envelope magnetic stripe is near magnetic gauge tap G, and the normally-closed contact 1 of switch G disconnects, and normally-closed contact 2 is connected, at this moment, the 220V civil power is given battery B charging after capacitor C step-down, bridge rectifier rectification, voltage-stabiliser tube W voltage stabilizing.When refrigerator doors was opened, door sealed magnetic stripe away from magnetic switch G, its normally opened contact 1 closure, and battery B to the LED power supply, lights LED through switch contact 2.
Under situation about having a power failure, because LED powers to it by battery B, therefore, refrigerator still can throw light on.
Claims (2)
