Description
본 발명은 고보조명 장치에 관한 것으로, 보다 상세하게는 차도용이나 디지털 사이니지 장치용로 사용할 수 있는 고보조명 장치 및 그 제작 방법에 관한 것이다.The present invention relates to a high auxiliary lighting device, and more particularly, to a high auxiliary lighting device that can be used for driving or a digital signage device and a manufacturing method thereof.
고보조명 장치는 극장 조명, 건축 조명, 호텔, 레스토랑, 오피스 공간 등에서 착색광(colored light)을 이용하여 장면 설정이나 분위기를 조성하는데 주로 이용된다.The high auxiliary lighting device is mainly used to set a scene or create an atmosphere using colored light in theater lighting, architectural lighting, hotels, restaurants, office spaces, and the like.
최근, 고보조명 장치는 가게 앞의 도로에 간판을 대신하여 로고 이미지를 투사하거나 가게에서 판매하는 상품에 대한 광고 내용을 투사하는데 이용되는 등, 그 사용범위가 확대되고 있다.Recently, high-auxiliary lighting devices are being used to project a logo image on the road in front of a store instead of a signboard or to project advertisements for products sold in the store.
이러한 고보조명 장치는 다색 LED(light emitting diode)를 구비함으로써 색상을 바꾸기 위해 필터를 설치할 필요가 없을 뿐만 아니라 다수의 LEDs를 조합하여 거의 모든 조명 색상을 생성하고 LED에 결합된 전자기기에 의해 조명 색상을 원격 변경할 수 있다. 또한, 다양한 색상의 생성이나 변경은 자동 프로그래밍 방법을 통해 수행할 수 있는 장점이 있어, 그 시장이 급속히 성장하고 있다.Since this high-auxiliary lighting device has multi-color LEDs (light emitting diodes), it is not necessary to install a filter to change the color, and almost all lighting colors are generated by combining a plurality of LEDs, and the lighting color can be changed by electronic devices coupled to the LEDs. can be changed remotely. In addition, there is an advantage in that generation or change of various colors can be performed through an automatic programming method, and the market is rapidly growing.
그러나, 기존 고보조명 장치 대부분은 이미지 크기 및 식별 한계로 인하여 인도 혹은 벽면에 투사하고 있으며, 아직까지 도로 상의 교통 상황이나 위험 상황 등을 실시간 운전자에게 전달하기 위한 용도로 사용되고 있지는 못하다.However, most of the existing high-auxiliary lighting devices are projected onto sidewalks or walls due to image size and identification limitations, and have not yet been used for conveying traffic or dangerous situations on the road to drivers in real time.

전술한 구성에 의하면, 광학계 각각의 정렬과 고정을 위해 각각의 렌즈와 렌즈군을 선택적으로 분류하여 근거리간 구성되어 있는 렌즈들을 3군으로 설정하고 이를 브라켓 프레임과 여러 고정용 브라켓으로 지지하도록 설계하고 장치 구성을 소형화할 수 있다.According to the above configuration, each lens and lens group are selectively classified for alignment and fixation of each optical system, and the lenses composed of short distances are set into three groups and designed to be supported with a bracket frame and several fixing brackets, The device configuration can be miniaturized.
또한, 기구부 대부분의 재질을 알루미늄이나 TIM(Thermal Interface Material)로 형성할 수 있으며, 그 경우 경량화, 가공용이성 및 방열 특성에서 우수한 장점을 가질 수 있다. 브라켓이나 알루미늄 재질에 대한 아노다이징 등 표면 처리를 수행하면, 난반사를 제거하고 경도를 향상시킬 수 있다. 외함 또는 하우징의 경우, 절곡 타입의 소정 두께의 알루미늄 재질로 형성할 수 있다.In addition, most of the mechanical parts may be made of aluminum or TIM (Thermal Interface Material), and in this case, light weight, ease of processing, and excellent heat dissipation characteristics may be obtained.

도 15는 도 13의 렌즈 어셈블리의 고보시스템 레이아웃을 설명하기 위한 도면이다.FIG. 15 is a view for explaining a gobo system layout of the lens assembly of FIG. 13 .
도 15를 참조하면, 본 실시예에서 렌즈 어셈블리의 길이(L1)는 255㎜이고, 그 직경(D1)은 70㎜이다. 실제로 렌즈 어셈블리는 작업자가 한 손으로 간단히 잡을 수 있는 정도의 사이즈를 가진다.Referring to FIG. 15 , in this embodiment, the length L1 of the lens assembly is 255 mm and the diameter D1 is 70 mm. In fact, the lens assembly has a size that a worker can simply hold with one hand.
렌즈 어셈블리는 오른쪽에서부터 기재된 순서대로 LED 광원(121), 콜리메이터 렌즈(122) 및 메인 렌즈(124)를 구비한 광원 모듈이 위치하고, 고보이미지 필터(165)를 사이에 두고 광원 모듈과 마주하는 측에 결상 모듈이 설치되는 구조를 가진다.In the lens assembly, in the order described from the right, the light source module including the LED light source 121, the collimator lens 122, and the main lens 124 is located, and the gobo image filter 165 is placed on the side facing the light source module. It has a structure in which an imaging module is installed.
렌즈 어셈블리가 회로부와 결합하여 고보조명 장치를 구성하면, 회로부의 광원 제어부에 의해 광원 모듈이 관리되고, 고보이미지 생성부에 의해 고보이미지 필터(165)의 위치가 관리되고, 포커싱 제어부에 의해 결상 모듈이 관리될 수 있다.When the lens assembly is combined with the circuit unit to form a high auxiliary lighting device, the light source module is managed by the light source controller of the circuit unit, the position of the gobo image filter 165 is managed by the gobo image generator, and the imaging module is managed by the focusing controller. this can be managed.
LED 광원(121)에서 생성되는 광은 콜리메이터 렌즈(122)와 메인 렌즈(124)를 통해 집광되어 회전판에 조사된다. 회전판은 고보이미지 필터(165) 부분을 제외하고 광원 모듈과 결상 모듈 사이에서 광 전달을 차단하는 클로저로서 기능한다. 이때 광원 제어부는 고보이미지 필터(165)에 대한 최대 광량을 확보할 수 있도록 집광을 최적화할 수 있다. 또한, 광원 제어부는 메인 렌즈(124)의 틸트 제어를 통해 고보이미지의 균제도를 향상시킬 수 있다.The light generated from the LED light source 121 is condensed through the collimator lens 122 and the main lens 124 and then irradiated to the rotating plate. The rotating plate serves as a closure blocking light transmission between the light source module and the imaging module, except for the gobo image filter 165 portion. At this time, the light source controller may optimize light condensing so as to secure the maximum amount of light for the gobo image filter 165 . In addition, the light source controller can improve the uniformity of the gobo image by controlling the tilt of the main lens 124 .
고보이미지 필터(165)가 부착된 회전판에서는 회전판의 클러저 기능을 통해 광원의 광에 대한 분산 또는 무지향성 산란광을 최소화하고 고보이미지 필터(165)를 통과하는 유효 광도 영역을 가이드한다. 고보이미지 필터를 통과한 광은 고보이미지 형태를 위한 특정 라이트 빔 패턴으로 변환된다.In the rotary plate to which the gobo image filter 165 is attached, dispersion or non-directional scattering of light from the light source is minimized through the closure function of the rotary plate, and an effective luminous intensity area passing through the gobo image filter 165 is guided. The light passing through the gobo image filter is converted into a specific light beam pattern for the gobo image shape.
라이트 빔 패턴은 결상 모듈의 볼록 렌즈와 오목 렌즈의 배열을 통과한다. 이때, 포커싱 제어부에 의해 제어되는 포커싱 렌즈 액추에이터의 동작에 따라 결상 모듈의 렌즈 배열은 라이트 빔 패턴을 통해 출사되는 고보이미지의 아웃 포커싱과 인 포커싱을 제어하도록 조작된다.The light beam pattern passes through an array of convex and concave lenses in the imaging module. At this time, according to the operation of the focusing lens actuator controlled by the focusing controller, the lens arrangement of the imaging module is manipulated to control out-focusing and in-focusing of the gobo image emitted through the light beam pattern.
전술한 고보조명 장치의 렌즈 어셈블리의 구성에 의하면, 단순히 광원과 볼록 렌즈 및 클로저를 포함한 기존 조명 장치에 의한 고보이미지와 달리, 시정 거리가 먼 곳에서도 잘 인식되는 입체효과 고보이미지를 효과적으로 생성할 수 있다. 이러한 입체효과 고보이미지는 수십 미터 거리에서 떨어진 사람이나 운전자가 볼 때 노면에서 세워진 형태의 입체효과를 가진 고보이미지로 보여지므로, 차도용으로 사용가능하다.According to the configuration of the lens assembly of the above-described gobo lighting device, unlike gobo images by conventional lighting devices including a light source, a convex lens, and a closure, a three-dimensional effect gobo image that is well recognized even at a far viewing distance can be effectively generated. have. Since such a three-dimensional effect gobo image is seen as a gobo image with a three-dimensional effect in the form of a standing on the road when viewed by a person or a driver from a distance of several tens of meters, it can be used for road use.
또한, 본 실시예에 따른 고보조명 장치는 광원(121)으로서 멀티 패키지 어레이를 사용한다. 멀티 패키지 어레이는 복수의 LEDs가 광원(121)의 발광면에 인접하게 배열되고, 멀티 배열 렌즈를 사용하므로 점광원 형태의 단일 LED보다 상대적으로 출사면이 수배 내지 수십 내 넓은 면광원 형태를 가질 수 있다. 이러한 멀티 패키지 어레이를 광원(121)으로 이용하면, 광원(121)의 출사면에 위치한 렌즈의 굴절각에 따른 라이트 빔 패턴에서의 균제도 저하를 효과적으로 보상할 수 있다.In addition, the high auxiliary lighting device according to the present embodiment uses a multi-package array as the light source 121 . In the multi-package array, a plurality of LEDs are arranged adjacent to the light emitting surface of the light source 121, and since a multi-array lens is used, the emitting surface can have a surface light source type that is several times to several tens of times wider than a single LED in the form of a point light source. have. When such a multi-package array is used as the light source 121 , a decrease in uniformity in a light beam pattern according to a refraction angle of a lens located on an exit surface of the light source 121 can be effectively compensated for.
이와 같이, 본 실시예에서는 광원 모듈의 메인 렌즈(124)의 틸트 제어를 통한 조도 균제도 보상에 더하여 광원(121)의 멀티 패키지 디밍 구성을 통해 입체효과 고도이미지의 조도 균제도를 효과적으로 보상할 수 있다.As such, in this embodiment, in addition to compensating for the uniformity of illumination through the tilt control of the main lens 124 of the light source module, the uniformity of illumination of the three-dimensional effect elevation image can be effectively compensated through the multi-package dimming configuration of the light source 121.
일례로, 차도 상에 투사되는 입체효과 고도이미지에서 그 중간 및 상단 부분에서 조도 균제도의 불균형이나, 상단 부분과 하단 부분에서의 조도 균제도의 불균형이나, 상단 부분에서의 조도 균제도의 불균형이 나타날 수 있으나, 광원(121)의 멀티 패키지 디밍 구성과 메인 렌즈(124)의 틸트 제어를 통해 이를 보상하여 조도 균제도가 우수한 입체효과 고도이미지를 생성할 수 있다. 또한, 이러한 입체효과 고보이미지는 수십 미터 거리에서 떨어진 차량의 운전자가 볼 때 노면에서 세워진 형태의 입체효과를 가진 이미지로 보여질 수 있다(도 2 참조).For example, in the three-dimensional effect altitude image projected on the roadway, there may be an imbalance in the uniformity of illumination in the middle and upper part, an imbalance in the uniformity in illumination in the upper and lower parts, or an imbalance in the uniformity in illumination in the upper part. , It is possible to compensate for this through the multi-package dimming configuration of the light source 121 and the tilt control of the main lens 124 to create a three-dimensional effect altitude image with excellent illumination uniformity. In addition, such a three-dimensional effect gobo image can be seen as an image having a three-dimensional effect in a form erected on the road when viewed by a driver of a vehicle from a distance of several tens of meters (see FIG. 2).

도 20은 본 발명의 다른 실시예에 따른 고보조명 장치의 작동 방법에 대한 흐름도이다.20 is a flowchart of a method of operating a high auxiliary lighting device according to another embodiment of the present invention.
도 20을 참조하면, 고보조명 장치의 작동 방법은, 먼저 고보조명 노면표시영역 주변을 센서로 센싱할 수 있다(S201). 센서는 조명 장치가 설치되는 지주 등에 설치될 수 있다.Referring to FIG. 20 , in the operation method of the high auxiliary lighting device, first, the surroundings of the high auxiliary lighting road marking area may be sensed with a sensor (S201). The sensor may be installed on a support on which a lighting device is installed.
다음, 고보조명 장치의 제어 유닛은 주변 센싱에 따라 미리 설정된 타겟이 감지되었는지를 판단할 수 있다(S202). 타겟은 보행자, 결빙, 교통사고 등을 포함할 수 있다.Next, the control unit of the high auxiliary lighting device may determine whether a preset target is sensed according to ambient sensing (S202). Targets may include pedestrians, ice, traffic accidents, and the like.
상기 단계(S202)에서의 판단 결과, 타겟이 감지되면(S202의 Yes), 제어 유닛은 현재의 고보이미지 필터에 대응하는 패턴 필름을 타겟 이미지용으로 설정된 고보이미지 필터로 변경하거나 변경하고자 하는 고보이미지 필터가 타겟 이미지인 경우에 현재의 패턴 필름을 유지한다(S203).As a result of the determination in step S202, if the target is detected (Yes in S202), the control unit changes the pattern film corresponding to the current gobo image filter to the gobo image filter set for the target image or the gobo image to be changed. When the filter is the target image, the current pattern film is maintained (S203).
한편, 상기 단계(S202)에서의 판단 결과, 타겟이 감지되지 않으면, 현재의 프로세스를 종료하거나 타겟 감지 단계를 소정 시간 간격으로 주기적으로 혹은 간헐적으로 수행할 수 있다(S202의 No).Meanwhile, as a result of the determination in step S202, if the target is not detected, the current process may be terminated or the target detection step may be periodically or intermittently performed at predetermined time intervals (No in S202).
다음, 제어 유닛은 다시 주변 센싱을 통해 보행자 보행 중, 결빙 유지 또는 교통사고 처리 중 등과 같이 현재 상태나 현재 상황에 해당하는 타겟이 유지되는지를 감지한다(S204).Next, the control unit detects whether a current state or a target corresponding to the current situation is maintained, such as pedestrian walking, freezing maintenance, or traffic accident handling, through peripheral sensing again (S204).

도 21은 본 발명의 또 다른 실시예에 따른 고보조명 장치의 작동 방법에 대한 흐름도이다. 도 22는 본 실시예의 고보조명 장치의 점등 상태에 대한 예시도이다.21 is a flowchart of a method of operating a high auxiliary lighting device according to another embodiment of the present invention. 22 is an exemplary view of a lighting state of the high auxiliary lighting device according to the present embodiment.
도 21을 참조하면, 고보조명 장치는 네트워크를 통해 타겟 이미지 정보를 획득한다(S211). 타겟 이미지 정보는 디지털 사이니지를 위한 고보이미지 선택 정보, 고보이미지 식별 정보 등을 포함한다. 해당 고보이미지에 대한 고보이미지 필터는 고보조명 장치의 회전판에 적어도 하나 또는 복수 개가 미리 설치된다.Referring to FIG. 21 , the high auxiliary lighting device obtains target image information through a network (S211). The target image information includes gobo image selection information for digital signage, gobo image identification information, and the like. At least one or a plurality of gobo image filters for the corresponding gobo image are pre-installed on the rotating plate of the gobo lighting device.
다음, 고보조명 장치는, 기본 고보이미지를 출력하고 있는 상태에서(S212), 타겟 이미지 정보에 따른 고보이미지를 출력할 타겟 타이밍인지를 판단한다(S213).Next, the gobo lighting device, while outputting the basic gobo image (S212), determines whether it is the target timing to output the gobo image according to the target image information (S213).
타겟 타이밍인 경우, 고보조명 장치는 기설정된 타겟 고보이미지를 출력한다(S214). 타겟 타이밍이 아니면, 고보조명 장치는 기본 고보이미지의 출력 상태를 유지할 수 있다.In the case of the target timing, the gobo lighting device outputs a preset target gobo image (S214). If it is not the target timing, the high auxiliary lighting device may maintain the output state of the basic gobo image.
이와 같이, 고보조명 장치는 원격지의 제어 신호나 정보에 기초하여 기탑재된 복수의 고보이미지들 중 선택되는 특징 고보이미지를 출력할 수 있으며, 또한 설정되는 시간에 따라 간헐적으로 혹은 주기적으로 특정 고보이미지를 출력하도록 구성될 수 있다. 이러한 구성에 의하면, 고보조명 장치는 디지털 사이니지 장치로 사용될 수 있으며, 미리 설치되는 고보이미지의 종류에 따라 차도용의 고보이미지 외에 다양한 문구, 광고 카피, 홍보 문구나 홍보 문양 등을 표시할 수 있음은 물론이다(도 22 참조).In this way, the high-auxiliary lighting device may output a characteristic gobo image selected from a plurality of pre-loaded gobo images based on a control signal or information from a remote place, and also intermittently or periodically according to a set time, a specific gobo image. It can be configured to output.

또한, 본 실시예에 따른 고보조명 장치는 등주 또는 지주의 높이와 조명의 조사 각도로 인해 다수 렌즈들의 조합과 굴절 렌즈의 굴절 각도 차이에 의한 이미지 왜곡(상하단 크기가 달라지는) 현상을 이용하며, 그에 의해 지면에 조사된 이미지의 하단이 짧고 상단이 긴 입체효과의 특징을 가진 고보이미지를 효과적으로 표시할 수 있다.In addition, the high-auxiliary lighting device according to the present embodiment uses a phenomenon of image distortion (the size of the upper and lower portions is different) due to a difference in the refractive angle of the combination of multiple lenses and the refractive lens due to the height of the light pole or support and the irradiation angle of the light. It is possible to effectively display a gobo image having a three-dimensional effect in which the lower part of the image irradiated on the ground is short and the upper part is long.
이러한 입체효과 고보이미지는 기존에 노면표시 즉, 반사도료를 이용해 주의, 규제, 지시, 보조표지 등을 표시하는 노면표시와 구별된다. 특히 본 실시예의 입체효과 고보이미지는 기존의 반사도료를 이용한 노면표시가 도로상황정보를 전혀 반영할 수 없는 것과 달리 변화하는 도로 상황에 대한 정보를 반영한 가변형 노면표시를 제공할 수 있다.This three-dimensional effect gobo image is distinguished from existing road markings, that is, road markings that display cautions, regulations, instructions, auxiliary signs, etc. using reflective paint. In particular, the three-dimensional effect gobo image of the present embodiment can provide a variable road surface display reflecting information on changing road conditions, unlike conventional road surface markings using reflective paint that cannot reflect road condition information at all.
