JPH02237346A - Telephone set with switch for turning on lighting device for incoming call at night - Google Patents

Abstract

PURPOSE:To secure the safety of a foot in a dark room by lighting the light automatically in the case of an incoming call at night and turning off the light after the prescribed time elapses after the termination of the call. CONSTITUTION:The telephone set is provided with a light sensor 7, a night detection circuit 6 detecting dark or bright state with the light sensor 7, an external lighting device 10 lighting the surrounding of a telephone set at least, a ringing detection circuit 5 detecting an incoming call, a call termination detection circuit 4 detecting the end of talking. When the telephone set is activated by the night information of the night detection circuit 6 and the ringing detection circuit 5 detects an incoming call, the external lighting device 10 is lit and after the termination of call is detected by the termination call detection circuit 4, a control circuit 8 controls the external lighting device 10 after the prescribed time elapses. Thus, the security of foot lighting is sufficiently attained.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a general telephone, and more specifically to a telephone that is designed to operate in conjunction with lighting equipment.

(Prior Art) When a call is received at night, if the room where the telephone is placed is dark, it is necessary to turn on the room light and confirm the location of the telephone.

(Problem to be solved by the invention) Therefore, when receiving a call at night, you have to grope for the light switch in a dark room, and you may bump into walls or
There is a danger of getting your foot caught on something and falling down.

Another disadvantage is that after a night call ends and the lights are turned off, it is difficult to move to a bedroom or the like because the room is dark.

The purpose of the present invention is to solve the above-mentioned drawbacks, and when a call is received at night, the lights are automatically turned on, and after the call is finished, the lights are turned off after a certain period of time, thereby ensuring safety underfoot in a dark room. When receiving a call at night, all telephones are equipped with lighting equipment and a switch to turn on the phone.

(Means for Solving All the Problems) In order to achieve all the above-mentioned objects, the present invention provides a telephone equipped with a lighting switch for turning on a lighting device when a call is received at night. an external illuminator that illuminates the phone, a ringing detection circuit that detects an incoming call, an end-of-call detection circuit that detects the end of a call, and a ringing detection circuit that detects the ringing when activated by the nighttime information of the nighttime detection circuit. A control circuit is provided for controlling the external illuminator to turn on the external illuminator when the circuit detects all incoming calls, and to turn off the external illuminator after a predetermined period of time has elapsed after the call termination detection circuit detects the end of the call.

(Example) Is this invention with reference to all the drawings below? I will explain in more detail.

FIG. 1 is a functional block diagram showing an embodiment of a telephone according to the present invention.

Parts directly related to the present invention are shown within the frame of one-dot chain lines. It is interfaced with the central office exchange 2 through a telephone line 3. It also has an interface with the external lighting fixture 10 as a switch 9. The optical sensor 7 detects the amount of light, and the night detection circuit 6 detects whether it is night or dark depending on the amount of light, and sends this information to the total control circuit 9. The ringing detection circuit 5 detects a ringing signal sent from the telephone exchange 2 and sends it as information to the money control circuit 8 that there is an incoming call. The end-of-call detection circuit 4 detects all on-hooks by the telephone operator, and sends end-of-call information to the total control circuit 8.

The control circuit 8 closes the external lighting switch 9 when it identifies that the call is received at night, and opens the external lighting switch 9 after a certain period of time has elapsed using a timer built into the control circuit after the call ends.

The control circuit 8 receives nighttime information from the nighttime detection circuit 6! lil-
It only works when receiving data. When there is an incoming call from the central office exchange 2, the ringing detection circuit 5 is activated to notify the control circuit 8 of the incoming call. The control circuit 8 fully recognizes that there is an incoming call at night, and completely closes the external lighting switch 9.

This turns on the lights in the room.

Next, when the call ends (when the telephone subscriber goes on-hook), the call end detection circuit 4 detects the end of the call and sends out call end information, so the control circuit 8 starts operating its own built-in timer. and after a certain period of time (for example, after 30 seconds)
Open the external light switch. This turns off the lights in the room.

(Effects of the Invention) As explained above, the present invention is configured so that when a telephone call is received at night when there is no lighting, the room lighting is automatically turned on due to the incoming call. There is no need to search for the switch on the appliance, you can respond to a call while keeping your feet clear, and you can safely leave the phone even after the call is over.
