Abstract

The utility model discloses an automatic illuminating lamp for a book cabinet. The automatic illuminating lamp comprises a power supply G, a magnetic control switch, a light control switch and an LED (Light-Emitting Diode) lamp L, wherein the magnetic control switch comprises a reed pipe E and a magnet S; the light control switch comprises a potential device RP, a photosensitive resistor RL and a power switch integrated block A; the pin 1 of the power switch integrated block A is electrically connected to the anode of the power supply G through the reed pipe E; the potential device RP is electrically connected between the pin 1 and the pin 5; the photosensitive resistor RL is electrically connected between the pin 5 and the pin 4, and the pin 4 is electrically connected with the cathode of the power supply G; and the LED lamp L is electrically connected between the pin 2 or pin 3 of the cathode of the power supply G. The illuminating lamp can be lightened once the book cabinet is opened at night; and a circuit is always cut off through the light control switch during the day, so that the illuminating lamp is not returned on. The automatic illuminating lamp has a simple structure, and is very convenient to use; and power consumption can be saved.

Description

The automatic illuminating lamp of bookcase

Technical field

The utility model relates to a kind of automatic illuminating apparatus, is specially the automatic illuminating lamp of a kind of bookcase.

Background technology

Bookcase on the existing market all is not provided with internal lighting device; At light during more weak or night; From bookcase, get book and will become very inconvenient; Can conveniently get book through hand-held lighting device or room lighting ceiling light, but still be inconvenience sometimes, therefore needs are a kind of can bookcase lighting device simple to operation, that can throw light on automatically when getting book.

The utility model content

The purpose of the utility model provides the automatic illuminating lamp of a kind of bookcase, from bookcase gets the book very problem of inconvenience at light during more weak or night to solve prior art.

For achieving the above object, the technical scheme that the utility model adopts is:

The automatic illuminating lamp of a kind of bookcase; Comprise power supply G, magnetic switch, light-operated switch and LED lamp; It is characterized in that: said magnetic switch comprises tongue tube E and magnet S, and said magnet S can make tongue tube E conducting when the bookcase door is opened, and when the bookcase door is closed, tongue tube E is ended; Said light-operated switch comprises potentiometer RP, photo resistance RL and power switch integrated package A; 1 pin of said power switch integrated package A is electrically connected on the positive pole of power supply G through tongue tube E; Be electrically connected with potentiometer RP between 1 pin and 5 pin; Be electrically connected with photo resistance RL and 4 pin between 5 pin and 4 pin and be electrically connected on the negative pole of power supply G, be electrically connected with the LED lamp between 2 pin or 3 pin and power supply G negative pole.

The automatic illuminating lamp of described a kind of bookcase is characterized in that: said power supply G is that No. 5 dry cells of four joints are composed in series; The model of said power switch integrated package A is TWH8778; Said photo resistance RL selects the common photo resistance of MG44-02 plastic resin-encapsulated for use, or selects other bright resistance≤2K Ω, the photo resistance of resistance in the dark>=200K Ω for use; It is JAG-2-2 that said tongue tube E selects model for use.

The beneficial effect of the utility model is:

The utility model adopts magnetic control and light-operated two master switch; When night, open the bookcase door and can light illuminating lamp; Pass through light-operated switch cut-off circuit all the time daytime, can not light illuminating lamp when therefore opening the bookcase door by day, the utility model is simple in structure; Use very conveniently, and can save electricity consumption.

Fig. 1 is the utility model circuit theory diagrams.

The specific embodiment

As shown in Figure 1, the utility model comprises power supply G, magnetic switch, light-operated switch and LED lamp L, and magnetic switch comprises tongue tube E and magnet S, and magnet S can make tongue tube E conducting when the bookcase door is opened, when the bookcase door is closed, tongue tube E is ended; Light-operated switch comprises potentiometer RP, photo resistance RL and power switch integrated package A; 1 pin of power switch integrated package A is electrically connected on the positive pole of power supply G through tongue tube E; Be electrically connected with potentiometer RP between 1 pin and 5 pin; Be electrically connected with photo resistance RL and 4 pin between 5 pin and 4 pin and be electrically connected on the negative pole of power supply G, be electrically connected with LED lamp L between 2 pin or 3 pin and power supply G negative pole.

Power supply G adopts No. 5 dry cells of four joints to be composed in series; The model of power switch integrated package A adopts TWH8778; Photo resistance RL selects the common photo resistance of MG44-02 plastic resin-encapsulated for use, or selects other bright resistance≤2K Ω, the photo resistance of resistance in the dark>=200K Ω for use.

The utility model adopts magnetic control and light-operated two master switch; When opening the bookcase door daytime and getting book,, make the inner normally-closed contact of tongue tube E lose outer magneticaction and rely on self elasticity connection though be fixed on small magnet on the cabinet door away from tongue tube E; But because of photo resistance RL receives natural light irradiation is low resistance; Control end 5 pin of power switch integrated package A are in low level (L1-6V), break off between input 1 pin and output 2,3 pin, so LED lamp L do not have electricity can be not luminous.

In the circuit, the control level of power switch integrated package A the 5th pin just depends on potentiometer RP and the photo resistance RL dividing potential drop to power supply G.Appropriate change potentiometer RP resistance can change same receiving under the optical condition, the dividing potential drop size at photo resistance RL two ends, thus make light-operated sensitivity be able to regulate.

Claims

1. automatic illuminating lamp of bookcase; Comprise power supply G, magnetic switch, light-operated switch and LED lamp; It is characterized in that: said magnetic switch comprises tongue tube E and magnet S, and said magnet S can make tongue tube E conducting when the bookcase door is opened, and when the bookcase door is closed, tongue tube E is ended; Said light-operated switch comprises potentiometer RP, photo resistance RL and power switch integrated package A; 1 pin of said power switch integrated package A is electrically connected on the positive pole of power supply G through tongue tube E; Be electrically connected with potentiometer RP between 1 pin and 5 pin; Be electrically connected with photo resistance RL and 4 pin between 5 pin and 4 pin and be electrically connected on the negative pole of power supply G, be electrically connected with the LED lamp between 2 pin or 3 pin and power supply G negative pole.
