Abstract
The utility model relates to an automatic illuminating lamp used in a book cabinet, comprising a power source, a magnetic switch, a photosensitive resistor, a power switch integrated circuit and a lamp bulb, wherein the power source, the magnetic switch and the power switch integrated circuit are formed into a series circuit; the photosensitive resistor and the bulb are respectively connected with the power switch integrated circuit; the magnetic switch consists of a piece of magnet and a dry reed pipe arranged on a book cabinet door. When using the utility model, the small magnet fixed on the cabinet door is kept away from the dry reed pipe; therefore, the normally closed contact arranged inside the dry reed pipe is no longer under the action of external magnetic force, and is switched on by means of self elasticity; meanwhile, the photosensitive resistor presents high resistance under the irradiation of natural light, which ensures that a pin 5 is at high level (more than or equal to 1.6V) and that output ends 2 and 3 are switched on; therefore, the bulb shines under the two indispensable conditions. The utility model has the advantages of simple structure, convenient operation and the realization of preset functions.
Description
Technical field
The utility model relates to the automatic illuminating lamp of a kind of bookcase, specifically uses photo resistance and magnetic switch and realizes that Book cabinet lamp throws light on automatically.
Background technology
The most of bookcase that occurs on the market does not all add illumination functions now, and people have to hand the power supply illumination when will get book night, very inconvenient.A kind of lamp that is clamped on the bookcase occurred, but the overall performance of this lamp and bookcase is bad, sometimes is difficult to combine.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the utility model provides a kind of simple in structure, easy to operate, the automatic illuminating lamp of bookcase that can realize required function.
The utility model is achieved through the following technical solutions: the automatic illuminating lamp of a kind of bookcase, by power supply, magnetic switch, photo resistance, power switch circuit, bulb, power supply, magnetic switch and power switch circuit are formed a series circuit, and photo resistance is connected with power switch circuit respectively with bulb.
Magnetic switch is made up of magnet on the bookcase door and tongue tube.
When the utility model is used, be fixed on small magnet on the cabinet door away from tongue tube, make the inner normally-closed contact of tongue tube lose outer magneticaction and rely on self elasticity connection, simultaneously, the natural light irradiation photo resistance is high resistance, make 5 pin be high level (〉=1.6V), then output 2,3 pin are connected, bulb is luminous, and two conditions are indispensable.The utlity model has simple in structure, easy to operate, can realize advantages such as predetermined function.
Description of drawings
Fig. 1 is the utility model circuit diagram;
Wherein, 1, power supply, 2, magnetic switch, 3, power switch circuit, 4, photo resistance, 5, bulb
The specific embodiment
Embodiment: as Fig. 1, magnetic switch 2 is made up of magnet on the bookcase door and tongue tube E, and magnetic switch 2 is connected on 1 pin of power switch circuit 3, and photo resistance 4 is connected on 5 pin of power switch circuit, bulb 5 is connected on power switch 2,3 pin, and power supply 1 provides power for entire circuit.
Small magnet in the magnetic switch 2 is away from the tongue tube E in 2 magnetic switch, make the inner normally-closed contact of tongue tube E lose outer magneticaction and rely on self elasticity connection, simultaneously, natural light irradiation photo resistance 4 is high resistance, make 5 pin of power switch circuit 3 be high level (〉=1.6V), then output 2,3 pin are connected, and bulb 5 is luminous, and power supply 1 provides power for circuit.
