Figure 1 is a schematic diagram showing a general light irradiation device capable of controlling light output. Referring to FIG. 1, a general light irradiation device includes a lighting unit 10 and a control unit 30 that controls the light output of the lighting unit 10. The lighting unit 10 includes a light source 11 that irradiates light and a photodetector 15 that receives a portion of the light irradiated from the light source 11 and monitors the intensity of the light radiated from the light source 11. Here, a reflective member 13 having a window 13a may be installed on the light source 11. Most of the light emitted from the light source 11 is emitted to the outside through the window 13a, and some of the light is reflected from the reflection member 13 toward the photodetector 15.
광검출기(15)는 수광한 광의 강도에 따른 전기신호를 출력하며, 출력된 전기신호는 제어부(15)에 전달된다. 제어부(15)는 광검출기(15)로부터 입력된 전기신호의 값을 기초로 광원(11)에 인가되는 전력을 조절한다. The photodetector 15 outputs an electrical signal according to the intensity of the received light, and the output electrical signal is transmitted to the control unit 15. The control unit 15 adjusts the power applied to the light source 11 based on the value of the electrical signal input from the photodetector 15.
여기서 광검출기(15)의 감광성(Photosensitivity)은 A/W 또는 V/W로 표시된다. 광검출기(15)는 수광한 광(W)의 세기에 따라 전류(A) 또는 전압(V)의 변화값을 출력하여 광의 세기 값을 나타낼 수 있다.Here, the photosensitivity of the photodetector 15 is expressed as A/W or V/W. The photodetector 15 may indicate the intensity of light by outputting a change in current (A) or voltage (V) depending on the intensity of the received light (W).
광검출기(15)의 감광성(Photosensitivity)은 선택되는 광검출기에 따라 편차가 발생할 수 있다. 즉, 동일 브랜드의 동일 모델 및 동일 제조라인을 통하여 제조된 광검출기라 하더라도, 감광성을 측정하여 보면 편차가 발생한다. 예를 들어, 하마마츠(사)의 몇몇 타입별 포토다이오드(광검출기)의 전광 특성을 살펴보면, 표 1과 같이 동일한 타입의 포토다이오드라 하더라도 감광성 편차가 존재한다.Photosensitivity of the photodetector 15 may vary depending on the photodetector selected. In other words, even if photodetectors are manufactured by the same brand, the same model, and the same manufacturing line, deviations occur when measuring photosensitivity. For example, looking at the electro-optical characteristics of several types of photodiodes (photodetectors) made by Hamamatsu, there is a difference in photosensitivity even among photodiodes of the same type, as shown in Table 1.

또한, 광원(11)에서 조사된 광의 일부를 광검출기(15)가 수광하여 전기신호로 변경하는데, 동일한 조명유닛(10)을 제작하더라도 광분포(광분포 각도)가 일치하지 않기 때문에 광검출기(15)에 입사되는 광의 세기가 다를 수 있다. 그리고 반사부재(13)를 사용하는 경우, 반사부재의 조립 공차에 따른 반사위치 편차와 반사체의 표면 가공상태 등에 따른 반사되는 형태가 달라지게 되어 광검출기에 입사되는 광량이 다를 수 있다.상기한 광검출기의 특성을 고려하여, 일반적으로 조명유닛(10)과 제어부(15)를 포함하여 광조사장치를 구성함에 있어서 제어부(15)는 세팅된 조명유닛(10)의 상기한 편차에 기인한 오차를 보정하여 사용하고 있다.In addition, the photodetector 15 receives part of the light emitted from the light source 11 and changes it into an electrical signal. However, even if the same lighting unit 10 is manufactured, the light distribution (light distribution angle) does not match, so the photodetector ( 15) The intensity of incident light may vary. In addition, when using the reflecting member 13, the reflection position deviation according to the assembly tolerance of the reflecting member and the reflected shape depending on the surface processing condition of the reflector may vary, so the amount of light incident on the photodetector may be different. Considering the characteristics of the detector, in general, when constructing a light irradiation device including the lighting unit 10 and the control unit 15, the control unit 15 compensates for the error caused by the above-described deviation of the set lighting unit 10. It is used after correction.
따라서 종래의 광조사장치는 조명유닛(10)의 고장 내지 성능 저하 등의 원인으로 제어부(15)를 유지한 상태에서 조명유닛을 교체하고자 하는 경우, 단순히 조명유닛 교체만으로는 광조사장치가 정상적으로 작동하지 않을 수 있다. 즉 제어부(15)에 다른 광검출기 또는 이를 포함하는 조명유닛이 장착되는 경우, 제어부(15)에서는 광검출기의 측정 오차로 제어부(15)에 입력되는 전기신호가 다를 수 있어서 정확한 광량 제어를 할 수 없다. Therefore, in the conventional light irradiation device, when the lighting unit is replaced while the control unit 15 is maintained due to a malfunction or performance degradation of the lighting unit 10, the light irradiation device does not operate normally simply by replacing the lighting unit. It may not be possible. That is, when another photodetector or a lighting unit including the same is mounted on the control unit 15, the electrical signal input to the control unit 15 may be different due to measurement error of the photodetector, making it impossible to accurately control the amount of light. does not exist.
그러므로 제어부에 대해 조명유닛만을 교체 설치하고자 하는 경우 제어부의 교정 절차 없이는 사용이 어렵다는 문제점이 있다.Therefore, if you want to replace and install only the lighting unit for the control unit, there is a problem in that it is difficult to use without a calibration procedure for the control unit.

Additionally, among the configurations mentioned in various embodiments, similar configurations and related configurations in each embodiment may be replaced, replaced, or added. However, when explaining in detail the operating principle of an embodiment of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description will be omitted.
이하 첨부된 도면들을 참조하여, 본 발명의 실시예에 따른 조명유닛 및 이를 적용한 광조사장치를 상세히 설명하기로 한다.Hereinafter, with reference to the attached drawings, a lighting unit according to an embodiment of the present invention and a light irradiation device to which the same is applied will be described in detail.
도 2는 본 발명의 실시예에 따른 조명유닛을 보인 개략적인 도면이다.Figure 2 is a schematic diagram showing a lighting unit according to an embodiment of the present invention.
도 2를 참조하면, 본 발명의 실시예에 따른 조명유닛(100)은 본체(110), 광원(111), 광검출기(115) 및 저장부(210)를 포함한다.Referring to FIG. 2, the lighting unit 100 according to an embodiment of the present invention includes a main body 110, a light source 111, a photodetector 115, and a storage unit 210.
상기 본체(110)는 하우징을 의미하는 것으로, 용도에 따라 다양한 형상으로 변형하여 형성될 수 있다. 이 본체(110)는 광원(111)에서 조사된 광이 외부로 출사되도록 형성된 윈도우(113a)를 포함한다. 이 윈도우(113a)에는 광학부재(미도시)가 설치될 수 있다.The main body 110 refers to a housing, and can be formed into various shapes depending on the purpose. This main body 110 includes a window 113a formed so that the light emitted from the light source 111 is emitted to the outside. An optical member (not shown) may be installed in this window 113a.
광원(111)은 본체(110) 내에 설치되며, 소정 파장의 광을 생성하여 상기 본체(110) 외부로 조사한다. 이 광원(111)은 광을 생성 및 조사하는 것으로, 반도체 LED로 구성될 수 있다.The light source 111 is installed within the main body 110, generates light of a predetermined wavelength, and irradiates it to the outside of the main body 110. This light source 111 generates and irradiates light and may be composed of a semiconductor LED.
예를 들어 상기 광원(111)은 기판 상에 LED 칩이 장착된 유형인 칩온보드(Chip on Board; COB) 또는 표면실장형 LED(Surface Mount Device; SMD) 등으로 구성될 수 있다. 이 광원(111)에서 조사되는 광의 파장은 용도에 따라 다양하게 설정될 수 있다.For example, the light source 111 may be composed of a chip on board (COB), which is a type in which an LED chip is mounted on a board, or a surface mount type LED (Surface Mount Device (SMD)). The wavelength of light emitted from this light source 111 can be set in various ways depending on the purpose.
또한, 상기 광원(111)은 자외선 파장의 광을 조사할 수 있다. 자외선(Ultraviolet, 이하 ‘UV’라 함)은 파장 범위 10 ~ 400 nm(에너지 범위 3 eV ~ 124 eV)인 광으로서, 파장이 가시광보다 더 짧고 엑스선보다는 더 긴 전자기파의 총칭이다. 이 UV는 광자 에너지가 커서 물질에 흡수되면 분자 결합을 깨는 화학적 성질이 있으므로, 특유의 살균 반응 및 광화학 반응을 가지고 있다. 이로 인해, UV를 조사하는 UV 발광장치는 산업, 의료, 미용 등 많은 기술분야에서 활용되고 있다. 예를 들어, UV 발광장치는 UV의 광화학적 반응을 이용하여 액체 상태의 페인트, 잉크, 접착제 등을 딱딱하게 굳히는 장비인 UV 경화장치에 적용될 수 있다.Additionally, the light source 111 may irradiate light of an ultraviolet wavelength. Ultraviolet (Ultraviolet, hereinafter referred to as ‘UV’) is light with a wavelength range of 10 to 400 nm (energy range 3 eV to 124 eV), and is a general term for electromagnetic waves with a wavelength shorter than visible light and longer than X-rays. This UV has a chemical property of breaking molecular bonds when absorbed by a material due to its large photon energy, so it has a unique sterilizing reaction and photochemical reaction. For this reason, UV light-emitting devices that irradiate UV light are used in many technical fields such as industry, medicine, and beauty. For example, a UV light-emitting device can be applied to a UV curing device, which is equipment that hardens liquid paint, ink, adhesives, etc. using UV photochemical reactions.
윈도우(113a)에 설치되는 광학부재는 광을 본체(110)의 외부로 투과시키는 투명창 기능을 수행한다. 즉, 광학부재는 상기 광원(111)에서 조사된 광 중 대부분의 광을 소정 배율로 투과시킨다. 이 광학부재는 본 발명에 따른 조명유닛의 용도에 따라 양(+)의 굴절력을 가지는 렌즈, 음(-)의 굴절력을 가지는 렌즈 등으로 구성될 수 있다. 이 광학부재는 평판형 투명부재, 조사되는 광을 집속시키는 볼록렌즈를 포함할 수 있다.The optical member installed in the window 113a functions as a transparent window that transmits light to the outside of the main body 110. That is, the optical member transmits most of the light emitted from the light source 111 at a predetermined magnification. This optical member may be composed of a lens with positive (+) refractive power, a lens with negative (-) refractive power, etc., depending on the purpose of the lighting unit according to the present invention. This optical member may include a flat transparent member and a convex lens that focuses the irradiated light.
한편 광원(111)에서 조사된 광의 일부는 광검출기(115)로 조사된다. 상기 광검출기(115)는 본체(110) 내에 설치되며, 광원(111)에서 조사된 광의 적어도 일부를 수광하여 광원(111)의 광 강도를 모니터링 한다.Meanwhile, part of the light emitted from the light source 111 is emitted to the photodetector 115. The photodetector 115 is installed in the main body 110 and monitors the light intensity of the light source 111 by receiving at least a portion of the light emitted from the light source 111.
또한, 조명유닛(100)은 본체(110)의 윈도우(113a) 주위에 마련되는 반사부재(113)를 더 포함할 수 있다. 이 반사부재(113)의 내측면에는 반사면이 형성될 수 있다. 이 반사면은 입사광을 전반사시킬 수 있도록 전반사 코팅 되거나, 반사부재(113)를 유리 소재로 구성하고 임계각 보다 큰 각도로 광이 입사되도록 배치시킴으로써 전반사 시킬 수 있다. 또한, 반사면은 입사광을 확산 반사시킬 수 있도록 형성되는 것도 가능하다. 이에 따라 상기 광원(111)에서 조사된 광 중 적어도 일부 광은 반사부재(113)에 입사되며, 반사부재의 반사면에서 전반사 내지 확산 반사되어 광검출기(115)로 향하게 된다.Additionally, the lighting unit 100 may further include a reflective member 113 provided around the window 113a of the main body 110. A reflective surface may be formed on the inner surface of the reflective member 113. This reflective surface can be totally reflected by being coated with a total reflection coating to allow total reflection of the incident light, or by making the reflection member 113 made of a glass material and arranging it so that the light is incident at an angle greater than the critical angle. Additionally, the reflective surface may be formed to diffusely reflect incident light. Accordingly, at least some of the light emitted from the light source 111 is incident on the reflective member 113, and is either totally reflected or diffusely reflected from the reflective surface of the reflective member and is directed to the photodetector 115.
반사부재(113)를 포함하는 경우, 광검출기(115)는 광원(111)에 이웃되게 배치될 수 있다. 이 광검출기(115)는 광원(111)에서 조사되고 반사부재(113)의 반사면에서 반사된 광을 수광함으로써, 상기 광원(111)의 광출력을 모니터링 한다. 이 광검출기(115)는 광전변환소자(예를 들어, 포토다이오드)로서, 수광된 광량에 대응하는 전기신호를 출력한다.When including the reflective member 113, the photodetector 115 may be placed adjacent to the light source 111. This photodetector 115 monitors the light output of the light source 111 by receiving light irradiated from the light source 111 and reflected from the reflective surface of the reflective member 113.
