Description

Automatic on / off device for sleep light on phone

The present invention relates to a sleep light control device of a telephone, and more particularly, to a sleep light on / off device and method for automatically turning on or off the sleep light by sensing the brightness of the surroundings.

Typically, indoor lights in homes use fluorescent lamps or electric heat lamps, and are provided with sleeping lamps. And when you go to bed, by manually operating the switch to turn on the bedlight, and in the morning you need to turn off the bedtime only light, there was the inconvenience of operating the switch, and in the morning, the ambient light will brighten the bedlight only Since it is difficult to distinguish whether it is turned on, there is a problem in that unnecessary electricity is consumed because the light for sleeping only is not turned off.

Accordingly, an object of the present invention is to provide a bedlight on / off apparatus and method for installing a bedlight in the telephone to automatically turn on or off the bedlight according to the brightness of the surroundings to solve the above problems.

The present invention for achieving the above object, is provided with a sleep light that can illuminate the surroundings, turn on the sleep light when the surrounding environment is dark, turn off the sleep light when the surrounding environment becomes bright It is done.

2 is a control flowchart for turning on a sleeping light according to the brightness of the surroundings according to an embodiment of the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

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

The CPU 130 controls the overall operation of the phone and outputs a switching control signal to detect the brightness of the surroundings so that the sleeping lamp 110 turns on or off. The key matrix 100 includes keys for inputting control commands such as various functions and sleep setting keys and numeric keys 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 sleep lamp 110 by the switching control signal of the CPU 130. The sleeping lamp 110 is turned on or off according to the switching on / off of the lamp driving switch 220. The light sensor 250 detects the surrounding brightness. The A / D converter 240 converts the ambient brightness signal detected by the optical sensor 250 into a digital signal and applies it to the CPU 130. The DC power supply unit 230 supplies power to the indoor light 110 and the telephone. The voice processor 150 voice-processes the voice signal for the call connected to the trunk line. The microphone 200 inputs a voice signal. The speaker 190 outputs an electric voice signal as an audible signal. The first and second amplifiers 170 and 180 amplify and output the input / output signals of the microphone 200 and the speaker 190 to a predetermined level. The display device 120 displays each processing 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 it to the voice processor 150. The ring detection circuit 210 detects a ring incoming from the trunk line and provides the ring to the CPU 130.

2 is a control flowchart for turning on the sleeping lamp according to the brightness of the surroundings according to an embodiment of the present invention.

1 to 2, the operation of the preferred embodiment of the present invention will be described in detail.

In order to carry out the present invention, the sleep mode setting key provided in the key matrix 100 should be pressed to set the sleep mode.

First, the user presses the sleep light setting key provided in the key matrix 100 of the phone. Then, in step 101, the CPU 130 receives a key signal from the key matrix 100. Thereafter, the CPU 130 proceeds to step 102 and the CPU 130 checks whether the input key signal is a sleep light setting key. In step 103, the CPU 130 checks whether the input key signal is a sleep light release key, and if not, performs a function according to the input key signal and returns to step 101. However, if the sleep lamp release key proceeds to step 104, the CPU 130 generates a switch-off control signal and applies it to the lamp driving switch 220. Then, the lamp driving switch 220 is turned off so that the power supplied from the DC power supply unit 230 is not applied to the sleeping light 110, the sleeping light 110 is turned off. Here, the sleep light setting key can be implemented as a toggle switch which, for example, presses once to set the sleep light mode, and presses again to enter the sleep light release mode. However, if the sleep light setting key is set in step 102, the CPU 130 proceeds to step 105 and the CPU 130 detects whether the signal converted from the optical sensor 250 and digitally converted by the A / D converter 240 is brighter than the surrounding environment. In the step, a switch-off control signal is generated and applied to the lamp driving switch 220. At this time, since the lamp driving switch 220 is turned off and the power supplied from the DC power supply unit 230 is cut off, the sleeping lamp 110 is turned off. In step 107, the sleep light is kept off. In step 108, the sleep light release key is input from the key matrix 100. If the sleep light release key is not input, the process returns to step 101. To exit. In step 105, when the surrounding environment is dark, the CPU 130 proceeds to step 109 and generates a switching-on control signal to the lamp driving switch 220. Accordingly, the lamp driving switch 220 is turned on, and the power supplied from the DC power supply unit 230 is applied to the sleeping light 110 so that the sleeping light 110 is turned on. In step 110, while keeping the sleeper lamp 110 on, it is checked in step 111 that the sleeper light release key is input from the key matrix 100. If the sleeper light release key is not input, the process returns to step 101. If so, go to Step 104. In step 104, the CPU 130 generates a switch-off control signal and applies it to the lamp driving switch 220. Then, the lamp driving switch 220 is turned off so that the power supplied from the DC power supply unit 230 is not applied to the sleeping light 110, the sleeping light 110 is turned off.

As described above, the present invention detects the ambient brightness in the phone, and turns on the sleeping light when the ambient brightness is dark, and turns off the sleeping light when the ambient brightness is bright, and the user manually sets the separate sleeping light. There is a convenient advantage of not having to turn on / off.
