핸드폰 조명장치{cellularphone illuminator}Cell phone illuminator

본 발명은 절전식 핸드폰 조명장치에 관한 것으로, 보다 상세하게는 핸드폰의 조명장치에 있어서, 버튼(key-pad)을 입력하거나 폴더(folder)를 열거나 전화가 왔을 때 디스플레이 화면에 조명이 구동하도록 되어 있는 기존 회로에 광다이오드를 추가로 실장하여 주위의 밝기 환경에 따라 화면 조명 밝기를 조정함으로써 밝은 장소에서의 불필요한 조명을 제어하여 배터리를 절약할 수 있는 절전식 핸드폰 조명장치에 관한 것이다.The present invention relates to a power-saving mobile phone lighting device, and more particularly, in the lighting device of the mobile phone, the lighting is driven on the display screen when a button (key-pad), a folder (folder) is opened or a call is received. The present invention relates to a power-saving mobile phone lighting device that can save battery by controlling unnecessary lighting in a bright place by adjusting the screen lighting brightness according to the surrounding brightness environment by mounting an additional photodiode in an existing circuit.

최근 들어, 핸드폰은 또 다른 통신수단으로서 그 보급량, 보급층이 확대되어짐으로써 종래의 가장 기본적인 사용양태인 통화수단 이외에도 다이어리, 문자메시지, 모바일팅, 모바일게임 등 다양한 분야의 서비스를 즐길 수 있는 다기능 대체 통신장비로 자리 매김하고 있는 실정이다.In recent years, the mobile phone has been expanded as its communication volume as another communication means, a multi-functional alternative to enjoy services in various fields such as diary, text message, mobileting, mobile games, in addition to the most basic means of use of the conventional means of communication It is being established as a communication equipment.

한편, 일반적으로 핸드폰의 조명장치는 어두운 곳에서도 핸드폰의 디스플레이 화면을 볼 수 있도록 하기 위한 장치로써, 종래의 핸드폰 조명장치는 플립형 핸드폰의 경우에 있어서는 사용시 버튼을 누를 경우나 플립을 개방하였을 경우에, 폴더형 핸드폰의 경우에 있어서는 버튼을 누르거나 폴더를 개방하였을 경우에, 또는 전화가 수신되었을 경우등에, 상기 핸드폰 내에 내장된 마이컴에서 화면조명신호가 출력되어 구동회로를 통해 증폭된 전류가 발광다이오드에 흘러 디스플레이 화면이 조명되어지는 작동구조로 이루어져 있다.On the other hand, in general, the lighting device of the mobile phone is a device for viewing the display screen of the mobile phone even in a dark place, the conventional mobile phone lighting device in the case of a flip-type mobile phone when the button is pressed or the flip is open, In the case of a clamshell cell phone, when a button is pressed, a folder is opened, or a call is received, a screen light signal is output from a microcomputer built in the cell phone and current amplified through the driving circuit is applied to the light emitting diode. It consists of an operating structure that flows and the display screen is illuminated.

이와 같은 상기 핸드폰 조명장치는 어두운 곳에서 디스플레이 화면을 볼 경우에 매우 유용하게 쓰여지는 필수 구동장치이지만, 실내 또는 밝은 곳에서는 불필요하게 핸드폰의 조명장치가 구동되어 배터리의 에너지 소비를 촉진시키며, 특히 다양한 서비스기능에 따른 게임, 채팅, 문자메시지 등의 사용에 있어서도 불필요한 조명구동에 따른 에너지 소비가 촉진되어짐으로써 핸드폰 배터리의 사용시간을 더욱 단축시키는 문제점이 있었다.Such a mobile phone lighting device is an essential driving device that is very useful when viewing a display screen in a dark place, but the lighting device of a mobile phone is unnecessarily driven indoors or in a bright place to promote energy consumption of a battery, and in particular, In the use of games, chats, text messages, etc. according to the service function, there is a problem of shortening the use time of the mobile phone battery by promoting energy consumption due to unnecessary lighting driving.

그리고, 이러한 핸드폰 조명장치의 구동에 따른 핸드폰 배터리의 전력소모는 실제 전체 소모에너지의 거의 50% 이상이나 차지할 정도로 전력소모의 주요인이 되는 것이다.In addition, the power consumption of the mobile phone battery according to the driving of the mobile phone lighting device is the main factor of the power consumption to occupy almost 50% or more of the actual total energy consumption.

이에 기존의 핸드폰들은 일반적으로 자체 기능 중 조명장치를 제어하는 기능을 탑재하고 있는데, 이러한 핸드폰 조명장치의 제어기능은 사용자가 조명장치의 구동시간(예를 들면, 항상 꺼짐, 8초 켜짐, 20초 켜짐)을 선택함으로써 조명시간을 제어하는 방법과 조명설정기능(예를 들면, 일반 조명, 절전 조명)에 따른 조명구동의 선택에 의하여 조명을 제어할 수 있는 방법 등을 말하는 것이다.Conventional mobile phones are generally equipped with a function to control the lighting device of its own function, the control function of such a mobile phone lighting device allows the user to operate the lighting device (for example, always off, 8 seconds on, 20 seconds) The lighting time is controlled by selecting the lighting) and the method of controlling the lighting by selecting the lighting driving according to the lighting setting function (for example, general lighting or power saving lighting).

그러나, 이러한 조명제어수단들은 사용자가 필요에 따라 조명장치의 구동을 조작할 수 있다는 이점은 있으나, 일반 사용자의 대다수가 이러한 절전기능을 인지하지 못하고 있어 거의 사용이 이루어지지 않고 있으며, 더욱이 이러한 기능을 알고 있다 하더라도 사용자가 항상 직접적으로 절전기능을 선택 설정해주어야 한다는 불편한 점때문에 거의 사용을 기피하고 있는 실정이다.However, these lighting control means have the advantage that the user can operate the driving of the lighting device as needed, but the majority of general users are not aware of such a power saving function is rarely used, and furthermore, Even if you know that the user is almost always avoided because of the inconvenience of having to set the power saving function directly.

본 발명은 상기과 같은 종래의 핸드폰 조명장치의 문제점을 해결하기 위하여 안출된 것으로, 버튼을 입력하거나 폴더 또는 플립을 개방하거나 전화가 수신되었을 때등에 디스플레이 화면이 조명되도록 구동되는 종래의 회로에 광 센스(PHOTO SENSOR)를 추가로 실장함으로써 주위의 밝기 환경에 따라 화면 조명 밝기를 제어하여 밝은 장소에서 불필요한 화면조명에 따른 배터리의 에너지 낭비를 억제하여 핸드폰의 평균 사용시간을 연장시킬 수 있도록 함과 아울러 이에 따른 배터리의 잦은 충전을 줄일 수 있음으로써 핸드폰 배터리의 수명을 연장 시킬 수 있는 유용한 절전식 핸드폰을 제공하고자 하는 것을 그 목적으로 한다.The present invention has been made to solve the problems of the conventional mobile phone lighting device as described above, and the optical sense in the conventional circuit is driven so that the display screen is illuminated, such as when a button is pressed, opening a folder or flip, or when a call is received. By additionally installing PHOTO SENSOR, the screen lighting brightness can be controlled according to the surrounding brightness environment to prevent the waste of battery energy caused by unnecessary screen lighting in bright places and to extend the average usage time of the mobile phone. The aim of the present invention is to provide a useful power-saving cell phone that can extend the life of the cell phone battery by reducing the frequent charging of the battery.

It relates to a cell phone lighting device.

상기 광 센서는 일반적으로 포토다이오드가 사용되어지는데, 이는 p-n 접합 또는 정류성을 나타내는 금속과 반도체와의 접촉의 역방향 전류가 빛의 조사에 의한 광전기전력효과로 증가하는 것을 이용한 광전변환장치로서, 일정한 역 방향 전압을 가한 상태에서 빛을 받으면 전류가 흐르게 되고 빛이 없으면 포토다이오드내의 소자의 저항이 증가하여 전류가 흐르지 못하게 된다.The photoelectric sensor is generally used a photodiode, which is a photoelectric conversion device using a photoelectric conversion effect by increasing the reverse current of the contact between the metal and the semiconductor exhibiting a pn junction or rectification due to the irradiation of light, When light is received with the reverse voltage applied, current flows. Without light, the resistance of the device in the photodiode increases, preventing current from flowing.

이하, 첨부되는 도면에 의해 본 발명을 더욱 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 실시예를 도시한 개략도로서, 버튼(key-pad)을 누르거나 폴더(folder)를 개방하는 등 핸드폰 사용신호를 입력하는 입력부(1)와 상기 입력부(1)로부터 사용신호를 인식하여 조명제어신호를 발생하는 마이컴(micom)(3)과 상기 마이컴(3)으로부터 조명제어신호를 전달하는 구동회로부(5)와 상기 구동회로부(5)로 조명제어신호가 전달되면 주위의 광량을 인식하여 전류제어를 가능하게 하는 광 센서부(7)와 상기 광 센서부(7)에서 광량을 인식하지 못하게되면 상기 조명제어신호는 상기 구동회로부(5)를 통해 증폭되어 핸드폰 디스플레이 화면을 조명할 수 있도록 하는 발광 다이오드(LED)(9)로 이루어지는 구성을 갖는다.1 is a schematic diagram showing an embodiment according to the present invention, which is used from an input unit 1 and an input unit 1 for inputting a mobile phone use signal such as pressing a key-pad or opening a folder. When the illumination control signal is transmitted to the micom 3 that recognizes the signal and generates the illumination control signal, and the driving circuit unit 5 and the driving circuit unit 5 that transmits the illumination control signal from the micom 3, When the light sensor unit 7 and the light sensor unit 7 do not recognize the light amount by recognizing the light amount of the light, the illumination control signal is amplified by the driving circuit unit 5 to display the mobile phone display screen. It has a configuration consisting of a light emitting diode (LED) 9 to be able to illuminate.

도 2는 본 발명에 따른 실시예로서 포토다이오드가 추가 실장 된 휴대폰 조명장치의 회로도를 나타내는 도면이며, 본 발명의 작동을 회로를 통해 상술하면 다음과 같다.2 is a diagram illustrating a circuit diagram of a mobile phone lighting apparatus in which a photodiode is additionally mounted as an embodiment according to the present invention. Hereinafter, the operation of the present invention will be described with reference to a circuit.

먼저, 핸드폰의 버튼(key-pad)을 누르거나 폴더(folder)를 개방하는 등 핸드폰 사용신호를 입력하는 입력부(1)에서 사용신호를 인식하면, 상기 사용신호는 마이컴(micom)(3)을 통해 조명제어신호를 발생시키게 된다.First, when the input signal 1 inputs a mobile phone use signal such as pressing a button (key-pad) of a mobile phone or opening a folder, the use signal receives a micom 3. Through the illumination control signal is generated.

이때, 핸드폰 외부의 빛이 없어 포토다이오드에서 주위의 광량을 인식하지 못하게 되면 소자의 저항이 증가되어 트랜지스터1(TR1) 베이스에 흐르는 전류를 제어하여 트랜지스터1, 2(TR1, TR2)를 통해 증폭된 전류는 발광 다이오드(LED)(9)를 작동하게 하여 핸드폰 디스플레이화면에 조명이 들어오게 되는 것이다.At this time, if there is no light outside the cell phone and the photodiode cannot recognize the amount of ambient light, the resistance of the device is increased to control the current flowing through the transistor 1 (TR1) base to be amplified by the transistors 1 and 2 (TR1, TR2). The current causes the light emitting diode (LED) 9 to operate to illuminate the cell phone display screen.

한편, 핸드폰 외부의 빛이 존재하여 포토다이오드에서 주위의 광량을 인식하게 되면, 소자의 저항이 내려가게 되어 포토다이오드가 상기 조명제어신호전류를 제어하게 되어 트랜지스터1, 2(TR1, TR2)에 의해 Ic 전류량을 제어함으로써 발광 다이오드(LED)(9)의 발광을 억제할 수 있는 것이다.On the other hand, when the light from the outside of the mobile phone is present to recognize the amount of ambient light in the photodiode, the resistance of the device is lowered and the photodiode controls the illumination control signal current, which is caused by the transistors 1 and 2 (TR1 and TR2). By controlling the amount of Ic current, light emission of the light emitting diode (LED) 9 can be suppressed.

또한, 실외나 실내에서 화면을 보기에 지장이 없는 밝기가 유지되도록 R2 값을 조정할 수 있는 것이다.In addition, the R2 value can be adjusted to maintain the brightness without disturbing the view outdoors or indoors.

이와 같이, 본 발명에 따른 절전식 핸드폰 조명장치에 의하면 간단하면서도 저렴한 비용으로 디스플레이 화면의 조명을 쉽게 제어 할 수 있으며, 이렇게 불필요한 화면조명을 제어하여 사용할 수 있게 함으로써 배터리의 사용 시간을 연장할 수 있을 뿐만 아니라 핸드폰의 사용시간을 증대할 수 있는 효과를 안출할 수 있는것이다.As such, according to the energy-saving mobile phone lighting device according to the present invention, it is possible to easily control the lighting of the display screen at a simple and low cost, and to extend the use time of the battery by enabling the use of unnecessary screen lighting. In addition, it is possible to produce an effect that can increase the use time of the mobile phone.

더불어 본 발명은 상기 효과 이외에도 배터리의 에너지 소비를 줄임으로써 배터리의 충전 횟수를 감소시킬 수 있으며, 나아가 완전방전이 되지 않은 상태에서 충전함으로써 충전량이 줄어드는 배터리의 메모리이펙트(MEMORY EFFECT)현상을 줄이는 것 또한 가능하게 하여 전체적으로 배터리의 수명을 연장하게 할 수 있게 하는 것은 물론 이로 인한 폐배터리의 발생을 억제하게되어 산업 폐기물을 감소시킬 수 있어 환경적으로도 매우 유용한 현저한 효과를 안출한 발명인 것이다.In addition, the present invention can reduce the number of charge of the battery by reducing the energy consumption of the battery in addition to the above effect, and furthermore, to reduce the memory effect of the battery (MEMORY EFFECT) is reduced by the charge amount is not fully discharged It is possible to extend the life of the battery as a whole, as well as to suppress the generation of waste batteries, thereby reducing the industrial waste is an invention that produced a significant environmentally significant remarkable effect.
