Description

[Detailed Description of the Invention] The present invention relates to a mailbox having a nameplate with a night illumination device.

Conventionally, a doorbell pushbutton switch installed in a mailbox having a nameplate with a nighttime illumination device has an illumination device for the nameplate and is not provided with a position indicator lamp because it is relatively bright.

However, in reality, the illumination for removing the nameplate is backlit and directly shines into the eyes, making it difficult to see around the nameplate and making it difficult to locate the push button switch.

The present invention aims to solve the above-mentioned drawbacks.

Examples will be described below using figures.

1 to 5 show an embodiment of the present invention, in which a mailbox has a nameplate 3 with an automatic night illumination device 2 controlled by a photoelectric switch 1, and a doorbell is placed near the nameplate 3. In addition to providing a push button switch 5 for use, a position indicating lamp made of a light emitting diode 6 connected in parallel with the lighting device 2 and indicating the position of the push button switch 5 is provided.

In the figure, 10 is a mail slot, 11 is a milk receptacle, 12 is a panel for the push button switch 5, and 13 is a circuit block.

When the surroundings become dark, the resistance of the photoconductive element 7, which is more sensitive than CdS, increases, so the heat generated by the current flowing through the bimetal switch 8 decreases, the contact 9 is closed, and the lighting device 2 is automatically turned on. , a current flows through the light emitting diode 6 connected in parallel to the lighting device 2 through the rectifying diode 15 and the current limiting resistor 16, and the light emitting diode 6 provided inside the push button 14 of the push button switch 5 lights up to indicate the position of the push button switch 5. It is now possible to do this.

Next, when the surroundings become brighter, the resistance of the photoconductive element 7 decreases, the current flowing through the bimetal switch 8 increases, the contact 9 is opened, the lighting device 2 is turned off, and the light emitting diode 6 is also turned off. ing.

As described above, the present invention provides a mailbox having a nameplate with an automatic night illumination device controlled by a charging switch, in which a pushbutton switch for a doorbell is provided near the nameplate and is connected in parallel with the illumination device. It is equipped with a position indicator lamp to indicate the position of the push button switch, and the small push button switch for the doorbell is placed near the nameplate, which is the most conspicuous part, so it can be used during the day or at night. The pushbutton switch for the doorbell can be recognized using the nameplate as a guide, making it difficult to overlook it.Furthermore, even if the illumination device on the nameplate is backlit at night, the position indicator lamp lights up, making it easy to recognize the pushbutton switch for the doorbell. This has the effect that the location of the push button switch can be easily confirmed.

In other words, the present invention solves the problem that the doorbell push button switch, which is made more conspicuous by being placed near the nameplate, becomes difficult to see when the black device is turned on, by providing a position indicator lamp that is turned on in synchronization with the lighting device. This has the advantage that it is difficult to overlook the push button switch for the doorbell.
