프레넬 렌즈 모듈{A Fresnel Lens Structure of Unioned Directing PIR Sensor}Fresnel Lens Module of Fresnel Lens Structure of Unioned Directing PIR Sensor

본 고안은 프레넬 렌즈 모듈에 관한 것으로, 특히 PIR 센서와 프레넬 렌즈를 직접 끼움 결합시키도록하여 별도의 촛점을 마출필요 없이 간략한 결합구조를 갖도록 함으로써 작업을 단순화시키도록 한 것을 특징으로 하는 프레넬 렌즈 모듈에 관한 것이다.The present invention relates to a Fresnel lens module, in particular to the PIR sensor and the Fresnel lens by directly fitting the Fresnel characterized in that to simplify the work by having a simple coupling structure without having to separate the focus It relates to a lens module.

일반적으로 조명기기등에 사용되는 센서로서 초음파 센서 및 적외선 센서가 가장 많이 사용되며, 이들을 조합한 센서도 등장하고 있다.In general, ultrasonic sensors and infrared sensors are most commonly used as sensors used in lighting equipment, and sensors combining them are also emerging.

먼저, 도플러 원칙을 이용한 초음파 센서는 지역에 있는 물체에 초음파를 발사하여 되돌아오는데 걸리는 시간을 측정하여 작동한다. 따라서 지역에 있는 사람의 움직임은 음파가 변경된 주파수로 되돌아 오게 하며, 그 결과 도플러가 옮겨지고 점유가 탐지된다.First, the ultrasonic sensor using the Doppler principle works by measuring the time it takes to return an ultrasonic wave to an object in the area. Thus, the movement of a person in the area causes the sound waves to return to the altered frequency, resulting in the Doppler being moved and occupied.

상기 초음파 센서는 고도의 감지 성능을 과시하며 센서의 체적 운동 탐지능 력은 칸막이나 선반 같은 물리적 장벽 또는 공간의 내용에 의해 방해 받지 않는다는 장점이 있으며, 또한 초음파 센서는 변경되는 활동 수준과 공기의 흐름을 보상 하기 위하여 신호 탐지 경계를 자동으로 조절하는 첨단 신호처리 회로를 활용한다.The ultrasonic sensor exhibits a high level of sensing performance, and the volumetric motion detection capability of the sensor is not disturbed by physical barriers or space contents such as partitions or shelves, and the ultrasonic sensor has an altered activity level and air flow. To compensate for this, the advanced signal processing circuit that automatically adjusts the signal detection boundary is used.

한편, 적외선 센서(PIR)는 움직이고 있는 인간의 신체에서 발산하는 열과 배경이 되는 공간 사이의 차이를 감지함으로 점유를 감지한다. 명확한 가시광선에 의존하는 적외선 센서로는 고유한 프레넬 렌즈(Fresnel Lens)를 사용하여 커버지역을 구획으로 나눔으로써 작은 움직임의 탐지를 증가시킨다.On the other hand, the infrared sensor (PIR) detects the occupancy by detecting the difference between the heat emitted from the human body moving and the space of the background. Infrared sensors, which rely on clear visible light, use a unique Fresnel Lens to increase the detection of small movements by dividing the cover area into compartments.

그런데, 상기 프레넬 렌즈를 기판 하우징과 조립시에 PIR 센서와 일치시키기 어려운 문제점이 있었다.However, when the Fresnel lens is assembled with the substrate housing, it is difficult to match the PIR sensor.

즉, 상기 프레넬 렌즈는 기판 하우징의 전면에 설치하고, PIR 센서는 기판에 설치되는바, 상기 기판에 설치되는 PIR 센서와 기판 하우징에 설치되는 프레넬 렌즈의 위치를 정확히 일치시키기 여려우며, 이에 따라 PIR 센서와 프레넬 렌즈의 촛점이 일치하지 않아서 정확한 감지가 이루어지기 곤란해진다.That is, the Fresnel lens is installed on the front of the substrate housing, the PIR sensor is installed on the substrate, it is difficult to exactly match the position of the Fresnel lens installed on the substrate and the PIR sensor installed on the substrate, As a result, the focus of the PIR sensor and the Fresnel lens do not coincide, making accurate detection difficult.

결국, 종래에는 프레넬 렌즈를 기판 하우징에 장착하고 PIR 센서는 기판에 별도로 장착하는 관계로 두가지 구조물의 촛점을 맞추기 어려워 세밀한 센서 측정이 어려웠던 것이다.As a result, in the related art, since the Fresnel lens is mounted on the substrate housing and the PIR sensor is separately mounted on the substrate, it is difficult to focus the two structures, thus making it difficult to measure detailed sensors.

본 고안은 상기와 같은 문제를 해결코자 하는 것으로, PIR 센서와 프레넬 렌즈를 결합시켜, 별도로 촛점을 일치시키지 않아도 원할히 동작되도록 하는데 그 목적이 있다.The present invention is to solve the above problems, the purpose is to combine the PIR sensor and the Fresnel lens, so that the smooth operation without having to focus separately.

상기 목적을 달성하기 위한 수단으로,As a means for achieving the above object,

본 고안은 다수개의 요철이 측면과 바닥면에 형성된 반구형 형태의 프레넬 렌즈와; 상기 프레넬 렌즈를 통해 인체에서 발생되는 적외선을 검출하며, 측면 상부면에 결합을 위한 돌기부를 갖는 PIR 센서와; 상기 프레넬 센서와 PIR 센서 사이에 배치되어 일측은 프레넬 렌즈와 결합되는 제 1 원통형 주연부를 형성하고, 타측은 PIR 센서와 결합하는 제 2 원통형 주연부를 형성하며, 제 2 원통형 주연부에는 돌기부가 결합되는 결합홈을 형성한 결합용 가이드를 포함하여 구성함이 특징이다.The present invention is a hemispherical Fresnel lens formed of a plurality of irregularities on the side and bottom surface; A PIR sensor which detects infrared rays generated in the human body through the Fresnel lens and has a protrusion for coupling to an upper surface of the side surface; Disposed between the Fresnel sensor and the PIR sensor, one side forms a first cylindrical peripheral portion coupled with the Fresnel lens, the other side forms a second cylindrical peripheral portion coupled with the PIR sensor, and the protrusion is coupled to the second cylindrical peripheral portion. Characterized by including a guide for the coupling formed a coupling groove to be.

또한, 상기 제 1 원통형 주연부의 너비가 제 2 원통형 주연부의 너비보다 더 넓게 형성되는 것이 특징이다.In addition, the width of the first cylindrical peripheral portion is characterized in that it is formed wider than the width of the second cylindrical peripheral portion.

본 고안은 결합용 가이드를 이용하여 프레넬 렌즈와 PIR 센서를 결합시킴으로서 별도로 촛점을 맞추지 않아도 되므로 간단한 설계가 가능하여 설치비용과 시간을 절약할 수 있는 효과를 제공한다.The present invention combines a Fresnel lens and a PIR sensor by using a coupling guide, so that a simple design is possible because it does not need to focus separately, thereby providing an effect of saving installation cost and time.

이하에서 도면을 참조로 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 고안의 분해사시도이고,1 is an exploded perspective view of the present invention,

도 2는 본 고안의 결합 단면도로서,2 is a cross-sectional view of the present invention,

도시한 바와 같이 본 발명은 크게 프레넬 렌즈(100)와, PIR 센서(200)와, 결합용 가이드(300)로 이루어진다.As shown, the present invention largely consists of a Fresnel lens 100, a PIR sensor 200, and the coupling guide 300.

상기 프레넬 렌즈(100)는 측면과 바닥면에 다수개의 요철(110)이 형성되어 있으며, 상기 요철(110)을 통해 촛점이 집중되도록 한다.The Fresnel lens 100 has a plurality of irregularities 110 are formed on the side and the bottom surface, so that the focus is concentrated through the irregularities 110.

즉, 인체에서 발생되는 적외선를 한 곳에 모으기 위하여 굴절율의 차이를 줄여줘야 하는바, 프레넬 렌즈(100)의 표면에 존재하는 요철(110)에 의해서 굴절율이 조절되기 때문에 적외선을 한 곳에 집중시킬 수가 있다.That is, in order to collect the infrared rays generated in the human body in one place, the difference in refractive index should be reduced. Since the refractive index is controlled by the unevenness 110 present on the surface of the Fresnel lens 100, the infrared rays can be concentrated in one place. .

본 발명의 프레넬 렌즈(100) 역시 측면과 바닥면에 오목면과 볼록면이 연속되는 다수개의 요철(110)이 형성되어 있어, 상기 요철(100)을 통해 수집되는 적외선을 센서에서 감지하게 된다.Fresnel lens 100 of the present invention also has a plurality of concavo-convex 110 is formed in the concave surface and convex surface is formed on the side and bottom surface, the infrared collected through the concave-convex 100 is detected by the sensor .

상기 PIR 센서(200)는 센서를 내장한 하우징(통상 직육면체 형상임, 도시하지 않음)과 기판(도시하지 않음)에 접속하기 위한 연결라인(210)이 센서 하우징으로부터 연장되며, 상기 센서 하우징에는 결합용 돌기부(220)가 형성된다.The PIR sensor 200 includes a housing (usually a rectangular parallelepiped shape), a connection line 210 for connecting to a substrate (not shown), which extends from the sensor housing, and is coupled to the sensor housing. Dragon protrusion 220 is formed.

상기 프레넬 렌즈(100)와 PIR 센서(200) 사이에는 결합용 가이드(300)가 설치되는바, 결합용 가이드(300)의 일측은 프레넬 렌즈(100)와 결합되는 제 1 원통형 주연부(310)를 형성하고, 결합용 가이드(300)의 타측은 PIR 센서(200)와 결합하는 제 2 원통형 주연부(320)를 형성한다.The coupling guide 300 is installed between the Fresnel lens 100 and the PIR sensor 200, one side of the coupling guide 300 is the first cylindrical peripheral portion 310 is coupled to the Fresnel lens 100 ) And the other side of the coupling guide 300 forms a second cylindrical peripheral portion 320 to be coupled to the PIR sensor 200.

또한, 프레넬 센서(100)의 너비가 PIR 센서(200)의 너비 보다 크게 제작되어야 하기 때문에 프레넬 렌즈(100)와 결합되는 제 1 원통형 주연부(310)의 너비(t1)가 PIR 센서(200)와 결합되는 제 2 원통형 주연부(320)보다 넓게 형성토록 한다.In addition, since the width of the Fresnel sensor 100 should be made larger than the width of the PIR sensor 200, the width t1 of the first cylindrical peripheral portion 310 coupled with the Fresnel lens 100 is the PIR sensor 200. It is to be formed wider than the second cylindrical peripheral portion 320 is coupled to).

상기 아울러, 상기 제 2 원통형 주연부(320)에는 PIR 센서(200)의 돌기부(220)가 결합되는 결합홈(330)을 더 형성하여 PIR 센서(200)와 결합용 가이드(200)가 용이하게 결합되도록 한다.In addition, the second cylindrical peripheral portion 320 is further formed with a coupling groove 330 to which the protrusion 220 of the PIR sensor 200 is coupled to facilitate coupling of the PIR sensor 200 and the coupling guide 200. Be sure to

특히, 상기 PIR 센서(200)의 본체가 제 2 원통형 주연부(320)에 접속되고, 돌기부는 제 2 원통형 주연부(320)의 테두리면에 결합되면서 보다 강력하게 PIR 센서(200)가 결합되도록 한다.In particular, the main body of the PIR sensor 200 is connected to the second cylindrical peripheral portion 320, the projection is coupled to the edge surface of the second cylindrical peripheral portion 320 so that the PIR sensor 200 is more strongly coupled.

이에 따라서 본 고안이 프레넬 렌즈(100)는 PIR 센서(200)와 항상 촛점이 일치한 상태를 유지하게 되며, 기판 하우징 제작시 상기 프레넬 렌즈(100)가 외부로 돌출되도록 제작하기만 하면 된다.Accordingly, the present invention has a Fresnel lens 100 is always maintained in the same state of focus with the PIR sensor 200, it is only necessary to manufacture so that the Fresnel lens 100 protrudes to the outside when manufacturing the substrate housing. .

즉, 종래에는 기판 하우징에 프레넬 렌즈를 설치하고 기판에 부착되는 PIR 센서와 일치시키도록 하였기 때문에 프레넬 렌즈와 PIR 센서의 촛점을 일치시키기 어려웠지만 본 고안에서는 프레넬 센서와 PIR 센서를 끼움 결합시킨 상태에서 기판에 고정하고 아울러 기판 하우징에 배치하기 때문에 PIR 센서와 프레넬 센서의 촛점이 원천적으로 맞추어지게 되는 것이다.That is, in the related art, it was difficult to match the focus of the Fresnel lens and the PIR sensor because the Fresnel lens was installed in the substrate housing and matched with the PIR sensor attached to the substrate. In this case, the focus of the PIR sensor and the Fresnel sensor will be inherently aligned since it is fixed to the substrate and placed in the substrate housing.
