Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a night lighting device for public phone booths installed on streets and the like.

[Conventional technology] Conventionally, the night lighting of this type of public telephone box was a fluorescent light of about 10W controlled by an automatic flasher, which turned on automatically at night and turned off automatically in the morning. It turns off the light.

[Problems to be solved by the invention] However, since the conventional system described above remains lit continuously during the night, the administrator of the public telephone box must also consider power consumption. For this reason, the brightness of the night lights mentioned above is kept to the minimum necessary, and as a result,
For example, when reading a telephone directory or the like in the public telephone box at night, problems such as insufficient illumination obviously arise.

[Means for Solving the Problems] The present invention provides a public telephone box equipped with a night lighting device, as a specific means for solving the above-mentioned conventional problems. The other is the interior lighting of the telephone box, and normally only the display is lit, and when the telephone is in use, the door switch and the telephone are turned on. The above-mentioned conventional problems can be solved by providing a public telephone box with an external display device, which is characterized in that a hook switch detects the entry of a user, turns on the indoor lighting, and turns off the display device. It is something to be solved.

[Example] Next, the present invention will be described in detail based on an example shown in the drawings.

What is indicated by the reference numeral 1 in FIG. 1 is a public telephone box, and its basic structure is similar to that of conventional public telephone boxes. The display 2 combined with a low power consumption light emitter such as an EL (electroluminescence) light emitting element is provided as one night lighting device, and the other night lighting device is a conventional public telephone box. An indoor lighting 3 for illuminating the inside of the box 1 is provided using a fluorescent light or the like.

What is shown in FIG. 2 is a control circuit for the night lighting device of the public telephone box 1 according to the present invention, and the power for all the lighting devices is supplied only at night by the automatic flasher 4 connected in series to the power source. It is becoming more and more common. At this time, the display 2
is turned on when the handset of one circuit 5a of the two-circuit, two-point hook switch 5 attached to the hook for hanging the handset of a telephone (not shown) is turned on, that is, when the telephone is not in use. Since the display 2 is connected to a power source through the contact 51a, the display 2 lights up when the telephone is not in use at night. The indoor light 3 is connected to a contact 52b of the other circuit 5b of the hook switch 5, which is turned on when the handset is disconnected. In addition, there is a momentary door which is installed on the door of the public telephone box 1 and whose contact is closed only while the door is open.
Connected to the power supply via switch 6, the door
Timer 7 is activated for a certain period of time by turning on switch 6.
It is also connected to the power supply via the contacts of a relay 8, which is turned on by a signal from the power source. By doing this, in the public telephone box 1, only the display 2 is lit at night, but when the user opens the door, the timer 7 is started by turning on the door switch 6, and the timer 7 is turned on at a constant rate. During the time period, the relay 8 is turned on to turn on the indoor lighting 3. If the user picks up the handset within this time period, the hook switch 5 will switch from the contacts 51a and 51b to the contacts 52a and 51b.
52b side, thereby the indoor lighting 3
continues to be lit, and the indicator 2 is turned off.
Furthermore, when the use of the telephone is finished, the hook switch 5 switches again to the contacts 51a and 51b to return to the initial state, but at this time, the door switch 6 is turned on again when the user leaves. , the indoor lighting 3 is also turned on for a certain period of time.

[Effects of the Invention] As explained above, the present invention provides a display in which a night illumination device for a public telephone box is combined with a luminous body on one side for displaying information to the outside, and on the other hand, the night illumination device for a public telephone box Normally, only the above-mentioned display is lit, and when the phone is in use, the door switch and phone hook are turned on.
By detecting the entry of a user by a switch, turning on the indoor lighting and turning off the display, when the public telephone box is not in use, the lighting of the display is consumed. In addition to significantly reducing power consumption, by providing a display on the outside of the public phone box, the location of the public phone box at night can be made clear, and by turning on the indoor lighting only when in use, Even if a sufficiently bright one is adopted, the problem of total power consumption can be solved and the problem of night lighting in the public telephone box can be eliminated, which is an excellent effect.
