The present invention relates to an automatic illuminance control device for an electric stand that automatically adjusts to a standard illuminance level when a difference occurs with an illuminance level.

일반적으로, 전기 스탠드에는 조도를 조절할 수 있는 조도가변형스위치부재가 설치되어 그 스위치부재를조작함으로써 사용자가 소망하는 적당한 빛의 양을 얻게 된다.In general, the electric stand is provided with a switch for changing the illuminance to adjust the illuminance to operate the switch member to obtain a suitable amount of light desired by the user.

그러나, 수동으로 조작하는 종래의 전기스탠드의 조도조절장치는 주위의 명암의 변화량과는 무관하게 단순히 전기스탠드의 광발산량만을 조절할 수 있는 것으로, 그러한 상태에서 장시간 학습내지는 작업을 하게될 경우 금방 눈의 피로를 느끼게 될 뿐만 아니라 시력이 저하되는 원인이 된다.However, the conventional light control device of the conventional electric stand can only adjust the light emission amount of the electric stand irrespective of the amount of change in the ambient light, and if such a long time learning or working in such a state, Not only do you feel fatigue, but it also causes your vision to deteriorate.

따라서, 본 발명은 상기한 사정에 비추어 이루어진 것으로, 그 목적은 주위의 명암 및 램프로부터의 광발산량을 검출할 수 있도록 전기스탠드의 소정위치에 광센서를 설치하여 그 광센서로부터 검출된 광량이 기준조도레벨과 차이가 발생하는 경우 자동으로 기준조도레벨로 조절되도록 하는 전기스탠드의 조도자동조절 장치를 제공함에 있다.Accordingly, the present invention has been made in view of the above circumstances, and an object thereof is to provide an optical sensor at a predetermined position of an electric stand so as to detect ambient light and the amount of light emitted from a lamp, and reference the amount of light detected from the optical sensor. The present invention provides an apparatus for automatically adjusting illuminance of an electric stand to automatically adjust to a standard illuminance level when a difference with the illuminance level occurs.

상기한 목적을 달성하기 위해 본 발명에 따른 전기스탠드의 조도자동조절장치는 램프로 이루어진 광출력부가 동작할수 있도록 전원을 제공하는 전원부를 갖춘 전기스탠드에 있어서, 주위의 명암 및 광출력부로부터의 광발산량을 검출하는 광검출부, 주위명암변화에 따른 기준조도레벨이 미리 저장되어 있는 기준조도레벨 기업부, 상기 광검출부에서 검출된 광량과 기준조도레벨기억부로부터의 기준조도 레벨을 비교하여 레벨차이가 발생하였을 경우 조절신호를 출력하는 비교제어부, 상기 비교제어부에서 출력되는 조절신호를 기초로하여 상기 광출력부의 조도를 조절하는 조도조절부를 구비하여 구성된다.In order to achieve the above object, the automatic adjustment of the illuminance of the electric stand according to the present invention is an electric stand having a power supply unit for providing a power to operate the light output unit made of a lamp, the light from the ambient light and light output unit A light detector for detecting the amount of divergence, a reference illuminance level in which the reference illuminance level according to the change in the ambient light is stored in advance, and a level difference between the light intensity detected by the light detector and the reference illuminance level from the reference illuminance level memory are compared. And a comparison control unit for outputting an adjustment signal when the control signal is generated, and an illumination control unit for adjusting the illuminance of the light output unit based on the control signal output from the comparison control unit.

상기와 같이 구성된 본 발명에 따르면, 광검출부에서 검출되는 광량을 비교 제어부에서 기준 조도레벨과 비교하여 레벨차이가 발생하게 되면 자동으로 광출력부의 조도를 조절해주게 된다.According to the present invention configured as described above, when the level difference occurs by comparing the amount of light detected by the photodetector with the reference illuminance level, the illuminance of the light output unit is automatically adjusted.

이하, 첨부된 도면을 참조하여 본 발명을 더욱 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described the present invention in more detail.

제1도는 본 발명에 따른 전기스탠드의 조도자동조절장치의 블록구성도로서, 참조부호 10은 광출력부(20)가 광을 발산시킬 수 있도록 전원을 제공하는 전원부로서, 통상적으로 가정 또는 사무실에서 설치된 콘센트(Plug Socket)로부터 전원을 공급받는다. 12는 주위의 명암 및 광출력부(20)로부터의 광발산량을 검출하는 광검출부로서, 예컨대 포토다이오드와 같 은광전변환소자(photoelectic Conversion Element)로 구성 된다. 14는 주위명암변화에 따른 기준조도레벨이 미리 저장되어 있는 기준조도레벨기억부로서, 예컨대 EEPROM으로 구성된다.1 is a block diagram of a device for automatically adjusting the illuminance of an electric stand according to the present invention, and reference numeral 10 denotes a power supply unit that provides power to the light output unit 20 to emit light. Power is supplied from installed Plug Socket. 12 is a photodetector for detecting light intensity and the amount of light emitted from the light output unit 20, and is composed of a photoelectic conversion element such as a photodiode. Reference numeral 14 denotes a reference illuminance level storage unit in which a reference illuminance level in accordance with a change in ambient contrast is stored in advance, and is configured as, for example, an EEPROM.

동 도면에서, 16은 장치전체의 동작을 제어하면서 상기 광검출부(12)에서 검출된 광량과 기준조도레벨기억부(14)로부터의 기준조도레벨을 비교하여 레벨차이가 발생하였을 경우 조절신호를 출력하는 비교제어부로서, 바람직하게는 마이컴으로 구성된다. 18은 상기 비교제어부(16)에서 출력되는 조절신호를 기초로하여 스탠드의 조도를 조절하는 조도조절부이며, 20은 상기 조도조절부(l8)로부터 조절된 조도에 따라 스탠드의 광량을 발산하는 광출력부로서, 통상의 백열등 또는 형광등 등의 램프로 구성된다.In FIG. 16, the control unit 16 outputs a control signal when a level difference occurs by comparing the amount of light detected by the photodetector 12 with a reference illuminance level from the reference illuminance level storage unit 14 while controlling the operation of the entire apparatus. The comparison control unit is preferably composed of a microcomputer. 18 is an illuminance control unit for adjusting the illuminance of the stand on the basis of the control signal output from the comparison control unit 16, 20 is light for emitting a light amount of the stand according to the illuminance adjusted from the illuminance control unit (8) As an output part, it consists of lamps, such as a normal incandescent lamp or a fluorescent lamp.

상기와 같이 구성된 본 발명에 따른 전기스탠드의 조도자동조절장치에 의한 조도자동조절방법을 제2도의 플로우챠트를 기초로하여 설명하면 다음과 같다.The automatic illuminance adjusting method by the automatic illuminance adjusting device of the electric stand according to the present invention configured as described above will be described based on the flowchart of FIG. 2.

일단, 전기 스탠드의 전원이 온다면 단계 S21에서 광검출부(12)는 주위의 명암과 광출력부(20)를 이루는 램프로부터 발산되는 광을 검출하게 된다. 이어, 단계 S22에서 비교제어부(16)는 상기 광검출부(12)에서 검출된 광레벨이 기준조도레벨기억부(14)에 저장되어 있는 기준조도레벨과 동일한지를 비교하게 되는 바, 그 비교 결과 동일한 경우에는 상기 단계 S21의 동작을 반복수행하게 되는 반면, 동일하지 않을 경우에는 단계 S23에서 상기 비교제어부(16)는 그 검출된 광레벨이 기준조도레벨에 비해 높은지를 비교하게 된다. 그리하여 그 비교 결과, 기준 조도레벨보다 높을 경우 단계 S24에서 그 비교제어부(16)는 전원부(10)로부터 공급되는 전원의 양을 적게 공급하도록 조절신호를 출력하고, 단계 S23에서 상기 비교제어부(16)는 기준조도레벨에 비해 상기 검출된 광레벨이 낮은지를 비교하게 되는 바, 기준조도레벨보다 높을 경우 상기 단계S24의 동작을 반복수행하게 되는 반면, 기준조도레벨에 비해 상기 검출된 광레벨이 낮을 경우 단계 S26에서 상기 비교제어부(16)는 전원부(10)로부터 공급되는 전원의 양이 많이 공급되도록 조절신호를 출력하게된다.Once the electric stand is powered on, in step S21, the light detector 12 detects light emitted from the lamp forming the ambient light and the light output unit 20. Subsequently, in step S22, the comparison controller 16 compares whether the light level detected by the photodetector 12 is the same as the reference illuminance level stored in the reference illuminance level storage unit 14. In this case, the operation of step S21 is repeatedly performed. In contrast, in step S23, the comparison controller 16 compares whether the detected light level is higher than the reference illuminance level. Thus, when the comparison result is higher than the reference illuminance level, the comparison control unit 16 outputs a control signal to supply a small amount of power supplied from the power supply unit 10 in step S24, and the comparison control unit 16 in step S23. Compares whether the detected light level is lower than that of the reference illuminance level. When the detected light level is higher than the reference illuminance level, the operation of the step S24 is repeated, while the detected light level is lower than the reference illuminance level. In step S26, the comparison control unit 16 outputs an adjustment signal so that a large amount of power supplied from the power supply unit 10 is supplied.

그리하여, 상기의 단계 S24 및 S26에서의 비교제어부(16)로부터 출력되는 조절신호를 기초로하여 조도조절부(18)에서는 광출력부(20)의 광출력양을 자동으로 조절하게 된다.Thus, the illuminance control unit 18 automatically adjusts the light output amount of the light output unit 20 based on the control signal output from the comparison control unit 16 in the above steps S24 and S26.

상기와 같이 본 발명에 따른 전기스탠드의 조도자동조절장치에 의하면 광검출부에서 검출되는 광량을 비교제어부에서 기준조도레벨과 비교하여 레벨차이가 발생하게 되면 자동으로 전기스탠드의 조도를 이상적인 조도레벨로 조절해주게 되므로 수동으로 전기스탠드의 조도를 조절하는 종래의 방식에 비해 훨씬 간편할 뿐만 아니라 시력보호에도 큰 효과가 있다.As described above, according to the apparatus for automatically adjusting the illuminance of the electric stand according to the present invention, when the level difference is generated by comparing the amount of light detected by the light detector with the reference illuminance level, the illuminance of the electric stand is automatically adjusted to the ideal illuminance level. This is much easier than the conventional method of manually adjusting the illuminance of the electric stand, and has a great effect on protecting eyesight.
