Description

Automatic on / off devices and methods such as sleeping on a telephone

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a control device for sleeping on a telephone, and more particularly, to a sleeping on / off device and method for automatically detecting a brightness of a surrounding area and turning on /

Typically, the indoor light of each home uses a fluorescent lamp or an electric heat, and is provided with a sleep-only light. In addition, since the sleeping light is turned on manually by operating the switch when leaving the sleeping room, and the sleeping light is turned off again in the morning, there is an inconvenience that the switch must be operated. In addition, It is difficult to distinguish whether it is turned on or off, so that the sleeping exclusive use is not turned off and unnecessary electricity charges are consumed.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a sleeping on / off device and method for automatically setting a sleeping light or turning off a sleeping light according to the brightness of the surroundings by installing a sleeping light on a telephone set.

In order to achieve the above object, the present invention is characterized in that a sleeping light that can illuminate the surroundings is installed on a telephone, a sleeping light is turned on when the surrounding environment is turned on, and a sleeping lightening is turned off when the surrounding environment is bright .

FIG. 2 is a control flowchart for lighting sleep light according to the brightness of the surroundings according to the embodiment of the present invention.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a telephone set according to an embodiment of the present invention.

The CPU 130 controls the overall operation of the telephone, and detects the surrounding brightness to output a switching control signal to turn on or off 110 such as sleeping. The key matrix 100 includes keys for inputting control commands such as various functions and sleep setting keys, and a numeric key for performing a dialing function, and outputs key data corresponding to a key pressed by the user to the CPU 130. The lamp driving switch 220 controls the power supply to turn on and off the sleeping light 110 by the switching control signal of the CPU 130. Sleeping light 110 is turned on or off according to switching on / off of the lamp driving switch 220. The light sensor 250 senses the ambient brightness. The A / D converter 240 converts the ambient brightness signal detected from the optical sensor 250 into a digital signal and applies the digital signal to the CPU 130. DC power unit 230 supplies power to the interior lamp 110 and the telephone set. The voice processing unit 150 performs voice processing on the voice signal for communication connected to the CO line. The microphone 200 inputs a voice signal. The speaker 190 outputs an electric voice signal as an audible signal. The first and second amplifying units 170 and 180 amplify the input and output signals of the microphone 200 and the speaker 190 to a predetermined level and output the amplified signals. The display device 120 displays each process and operation state according to the key input state. The DTMF generator 140 generates a DTMF signal under the control of the CPU 130 and provides the DTMF signal to the audio processor 150. The ring detection circuit 210 detects a ring coming from the CO line and provides it to the CPU 130.

FIG. 2 is a control flowchart for lighting the sleeping light according to the brightness of the surroundings according to the embodiment of the present invention.

The operation of the preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 to 2. FIG.

In order to perform the present invention, the sleep mode setting key provided in the key matrix 100 must be set to the sleep mode.

The user first presses the sleep setting key provided in the key matrix 100 of the telephone set. Then, in step 101, the CPU 130 receives the key signal from the key matrix 100. Thereafter, the CPU proceeds to step 102 where the CPU 130 checks whether the inputted key signal is a sleep setting key, and proceeds to step 103 if it is not a sleep setting key. In step 103, the CPU 130 checks whether the inputted key signal is a sleep-release key and performs a function according to the inputted key signal if it is not a sleep-release key, and then returns to step 101. [ However, if the sleep release key is pressed, the CPU 130 generates a switch-off control signal and applies the switch-off control signal to the lamp drive switch 220 in step 104. The lamp driving switch 220 is turned off so that the power supplied from the DC power source 230 is not applied to the sleeping light 110, so that the sleeping light 110 is turned off. Here, the sleep setting key can be implemented by a toggle switch that is set to the sleep mode, for example, once, and is switched to the sleep mode or the like again when pressed. However, if the sleep setting key is selected in step 102, the CPU 130 checks whether the signal converted from the optical sensor 250 through the A / D converter 240 is lighter than the surrounding environment, A switch-off control signal is generated and applied to the lamp-driving switch 220. At this time, the lamp driving switch 220 is turned off, and the power supplied from the DC power source 230 is cut off, so that the sleeping light 110 is turned off. If it is determined in step 107 that the sleep key or the like is inputted from the key matrix 100 in step 108 and the sleep key or the like is not input in step 107, the process returns to step 101. If the sleep key, Lt; / RTI > If the surrounding environment is dark in step 105, the CPU 130 generates a switching-on control signal and applies it to the lamp driving switch 220 in step 109. Accordingly, the lamp driving switch 220 is turned on, the power supplied from the DC power source 230 is applied to the sleeping light 110, and the sleeping light 110 is turned on. In step 110, it is checked whether the sleep key or the like is input from the key matrix 100 in step 111. If the sleep key or the like is not inputted, the process returns to step 101, The process proceeds to step 104. In step 104, the CPU 130 generates a switch-off control signal and applies the switch-off control signal to the lamp-driving switch 220. The lamp driving switch 220 is turned off so that the power supplied from the DC power source 230 is not applied to the sleeping light 110, so that the sleeping light 110 is turned off.

As described above, according to the present invention, when the brightness of the surroundings is detected by the telephone, the sleeping light is turned on when the surrounding brightness is dark, the sleeping light is turned off when the surrounding brightness is bright, There is a convenient advantage of not having to turn on / off.
