Description

클러스터의 마이콤을 이용한 야간 조명 제어 장치{Night lighting control system using the micom of a cluster}Night lighting control system using the micom of a cluster}

본 발명은 클러스터의 마이콤을 이용한 야간 조명 제어 장치에 관한 것으로, 더욱 상세하게는 전류값에 따라 선형 변화를 일으키는 LED의 휘도 조절을 통해 벌브와의 조명 밸런스를 유지할 수 있도록 한 클러스터의 마이콤을 이용한 야간 조명제어 장치에 관한 것이다.The present invention relates to a night light control device using a micom of the cluster, and more particularly, night using a cluster of the micom to maintain the lighting balance with the bulb by adjusting the brightness of the LED causing a linear change according to the current value It relates to a lighting control device.

일반적으로 자동차에는 여러가지 조명 장치가 구비되어 있다. 특히, 차량의 실내에는 내부에 장착된 각 전기 장비들, 예를 들어 오디오, 히터, 컨트롤러 등을 야간에도 볼 수 있도록 하기 위한 표시등과, 차량의 상태 등을 운전자가 쉽게 알 수 있도록 클러스터 등에 사용되는 속도계나 음향계 그리고 기타 다른 성능을 나타내는 요소에는 지시등을 포함한다. 특히, 상기 표시등들은 보통 벌브를 많이 적용하여 사용하고 있으며, 상기 지시등으로는 보통 LED를 많이 사용하고 있다.In general, automobiles are equipped with various lighting devices. In particular, the interior of the vehicle is used in the cluster, so that the driver can easily know the status of the vehicle, such as an indicator light for viewing each electric equipment mounted inside, for example, audio, heater, controller, etc. Speedometers, acoustics and other performance indicators may include indicator lights. In particular, the indicators are usually used to apply a large number of bulbs, and the indicators are usually used a lot of LEDs.

이들 지시등과 표시등은 각각 벌브와 LED를 적용하고 있는데, 첨부도면 도 3에서 도시한 바와 같이, 서로 다른 휘도값을 가지고 있어 인가되는 전류값에 의해 밝기라든지 빛의 번짐 등이 달라 조명 밸런스가 맞지 눈부심 등으로 안전 운행을 방해하는 원인으로 작용하게 되었다.Bulbs and LEDs are applied to these indicators and LEDs, respectively. As shown in FIG. 3, each of the indicators and the indicator has different luminance values. It was acting as a cause of obstructing safe driving.

이를 해결하기 위해 운전석에서 운전자에 의해 임의로 조절가능하도록 가변 저항기(rheostator)를 장착하여 벌브의 휘도를 LED의 휘도에 맞게 조절할 수 있게 하는 방법이 적용되고 있다. 하지만, 이러한 벌브의 휘도 조절 방법은 벌브의 휘도가 어느 일정 구간에서는 급격히 어두워지는 반면에 LED는 이 구간에서도 시인이 가능한 휘도가 나오기 때문에 적절한 조절이 이루어지지 않게 되었다.In order to solve this problem, a method of mounting a variable resistor (rheostator) in the driver's seat so that the driver can arbitrarily adjust the luminance of the bulb according to the luminance of the LED has been applied. However, such a method of adjusting the brightness of the bulb, while the brightness of the bulb is rapidly darkened in a certain section, while the LED is visible in this section, the proper adjustment is not made.

즉, LED는 미세한 전류가 인가되더라도 빛을 발하게 되는 반면에 벌브는 일정 전류값 이상이 되어야만 빛을 발하기 때문에, 벌브를 제어하여 LED의 휘도 변화를 보상하는데에는 한계가 있어 이에 대한 개선이 필요하게 되었다.In other words, LED emits light even when minute current is applied, whereas bulb does not emit light until it reaches a certain current value. Therefore, there is a limit in compensating the brightness change of LED by controlling the bulb. It became.

본 발명은 이러한 점을 감안하여 안출한 것으로, 현재 인가된 전류값으로부터 LED와 벌브의 휘도값을 비교하고, 그 차이값만큼 LED의 휘도를 가변시켜 휘도 변화를 조절해 줌으로써 상이한 조명원의 조명 밸런스가 가능하도록 한 클러스터의 마이콤을 이용한 야간 조명 제어 장치를 제공하는데 그 목적이 있다.The present invention has been made in view of this point, and compares the luminance values of the LED and the bulb from the current applied current value, and adjusts the luminance change by varying the luminance of the LED by the difference value to adjust the illumination balance of different illumination sources. The purpose is to provide a night light control device using a cluster of microcomputer to enable.

이를 실현하기 위한 본 발명은 표시등과 지시등으로 사용되는 각종 벌브 및 LED와, 클러스터의 각 구성 요소들을 제어하는 마이콤으로 이루어지되, 상기 마이콤은 벌브와 LED에 인가되는 전류값을 검출하여 이때의 벌브와 LED의 휘도를 비교하고 그 그 차이값만큼 LED의 휘도를 가감하여 휘도를 조절하는 것을 특징으로 한다.The present invention for realizing this consists of a variety of bulbs and LEDs used as indicators and indicators, and the microcomputer to control the respective components of the cluster, the microcomputer detects the current value applied to the bulb and the LED and The brightness of the LED is compared and the brightness of the LED is adjusted by the difference value.

이하, 첨부도면을 참조하여 본 발명의 구성 및 작용 효과에 대해 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, the configuration and effect of the present invention will be described.

첨부도면 도 1은 본 발명에 따르는 야간 조명 제어 장치의 구성도이다. 여기서, 도면부호 10은 LED를, 20은 벌브를 각각 나타낸다.1 is a block diagram of a night light control apparatus according to the present invention. Here, reference numeral 10 denotes an LED and 20 denotes a bulb.

본 발명은 서로 다른 휘도 특성을 갖는 LED(10)와 벌브(20)의 조명 밸런스를 위해 클러스터의 마이콤(30)을 사용하여 벌브(20)의 휘도차이만큼 LED(10)의 휘도를 가감시켜 주도록 한 것이다.The present invention uses the microcomputer 30 of the cluster to balance the illumination of the LED 10 and the bulb 20 having different luminance characteristics so that the luminance of the LED 10 is increased or decreased by the luminance difference of the bulb 20. It is.

이를 좀 더 상세하게 설명하면, 본 발명은 표시등과 지시등 등으로 사용되는모든 LED(10) 및 벌브(20)와, 클러스터를 제어하기 위한 마이콤(30)을 포함하여 이루어진다.In more detail, the present invention includes all LEDs 10 and bulbs 20 used as indicators and indicators, and a microcomputer 30 for controlling a cluster.

여기서, 상기 마이콤(30)은 최근 속도계등과 같이 디지탈 디스플레이어를 적용하는 클러스터의 제어를 위해 사용되는 것으로, 특히 상기 가변 저항기(40)로부터 인가된 전류의 세기를 검출하게 된다. 또한, 상기 마이콤(30)에는 첨부도면 도 2에서 도시한 바와 같이, LED(10)와 벌브(20)의 휘도 특성 그래프(휘도-전압)가 미리 입력되어 있으며, 상기 가변 저항기(40)로부터 입력되는 전류값으로부터 현재 전류값에 대한 LED(10)와 벌브(20)의 휘도값을 구하게 된다. 이와 같이 상기 마이콤(30)은 현재 인가된 전류에 대한 휘도값을 구한 다음 그 차이값만큼 LED(10)의 휘도값을 보상해 주게 된다.Here, the microcomputer 30 is used for controlling a cluster to which a digital display is applied, such as a speedometer. In particular, the microcomputer 30 detects the strength of the current applied from the variable resistor 40. In addition, as shown in FIG. 2, the luminance characteristic graph (luminance-voltage) of the LED 10 and the bulb 20 is input to the micom 30, and is input from the variable resistor 40. The luminance values of the LED 10 and the bulb 20 with respect to the current current value are obtained from the current value. As described above, the microcomputer 30 calculates the luminance value of the currently applied current and compensates the luminance value of the LED 10 by the difference value.

이는, 첨부도면 도 2에서 도시한 바와 같이, 상기 LED(10)의 경우 미세하더라도 전압이 인가되게 되면 세기는 밝지 않으나 점등된 상태가 되고 벌브(20)의 경우 일정 전압 이상이 인가된 경우에만 점등이 이루어지기 때문에, 상기 벌브(20)의 휘도를 기준으로 하여 이에 맞게 LED(10)의 휘도를 조절해 줌으로써, 서로 다른 조명원인 LED(10)와 벌브(20)의 휘도를 조절하여 밝기가 같은 상태로 조절할 수 있게 된다.As shown in FIG. 2, when the voltage is applied in the case of the LED 10, the intensity is not bright, but is turned on, and in the case of the bulb 20, the bulb 20 is turned on only when a predetermined voltage or more is applied. Since it is made, by adjusting the brightness of the LED 10 according to the brightness of the bulb 20 as a reference, by adjusting the brightness of the LED 10 and bulb 20, which are different illumination sources, the brightness is the same Can be adjusted to the state.

또한, 상기 마이콤(30)은 벌브(20)가 점등되지 않는 구간, 첨부도면 도 2에서 비가변구간에 해당하는 전류가 벌브(20)에 인가되면, 상기 벌브(20)가 점등되지 않기 때문에 LED(10) 또한 점등 신호를 보내지 않게 된다.In addition, the microcomputer 30 is a section in which the bulb 20 is not turned on. When the current corresponding to the non-variable section is applied to the bulb 20 in FIG. 2, the bulb 20 is not turned on. (10) Also, no lighting signal is sent.

따라서, 상기 LED(10)는 벌브(20)의 휘도값을 중심으로 그 증감량만큼 마이콤(30)의 제어로 보상을 받게 되어 LED(10)와 벌브(20)의 휘도가 같아지게 되는 것이다.Therefore, the LED 10 is compensated by the control of the microcomputer 30 by the amount of increase and decrease based on the luminance value of the bulb 20 so that the luminance of the LED 10 and the bulb 20 are equal.

이상에서 본 바와 같이 본 발명은 클러스터의 마이콤을 통해 벌브의 휘도값과 비교하여 LED의 휘도값을 보상하여 줌으로써 다음과 같은 효과를 얻게 된다.As described above, the present invention provides the following effects by compensating the luminance value of the LED by comparing with the luminance value of the bulb through the microcomputer of the cluster.

1) 서로 다른 조명원인 벌브와 LED가 동일한 휘도값을 가지게 되어 조명 밸런스를 맞출 수 있게 된다.1) Bulbs and LEDs, which are different lighting sources, have the same luminance value, so that the lighting balance can be balanced.

2) 벌브와 LED의 밝기가 거의 동일하게 되어 운전자의 눈의 피로를 줄여 야간에 안전 운행에 도움을 주게 된다.2) The brightness of bulb and LED is almost the same, which reduces the eyestrain of the driver, helping to drive safely at night.
