작업면의 균일 고조도 유지를 위한 램프 반사갓 장치Lamp reflector device for maintaining uniformly high work surface brightness
본 발명은 작업면의 균일 고조도 유지를 위한 램프 반사갓 장치에 관한 것으로서, 더욱 상세하게는 광원에서 발생된 빛의 반사와 확산 및 집중 효율을 극대화할 수 있는 다단의 반사판이 결합된 구조로 이루어져 작업면에 고조도의 균일한 빛을 조사함과 아울러 빛을 고르게 확산시켜 눈부심을 방지함으로써 작업장의 조명 환경을 개선하고 빛의 반사효율이 향상됨에 따른 에너지 절감에 기여할 수 있는 작업면의 균일 고조도 유지를 위한 램프 반사갓 장치에 관한 것이다.The present invention relates to a lamp reflector device for maintaining a uniform high illuminance of the working surface, and more particularly, it consists of a structure in which a multi-stage reflector is combined to maximize the reflection and diffusion and concentration efficiency of light generated from the light source Uniform light of the work surface is irradiated and the light is diffused evenly to prevent glare, thereby improving the lighting environment of the workplace and maintaining the uniform light intensity of the work surface which can contribute to energy saving by improving the light reflection efficiency.

각종 조명기구에는 광원인 램프로부터 발생되는 빛을 반사시켜 사용자가 원하는 작업면에 집중하는 역할을 하는 다양한 형태의 반사갓이 적용되고 있다. Various lighting fixtures are applied to various types of reflection shades that reflect light generated from a lamp as a light source and concentrate a user's desired work surface.
조명등은 일반적으로 램프에서 발생된 빛의 총광속에서 하향광속이 대략 45%, 상향광속이 대략 55%로 분포된다. 램프 반사갓은 조명등에서 발생된 상향광속이 손실되지 않고 하향으로 집중되도록 함으로써, 반사갓 자체가 에너지를 절약하지는 않지만, 최적의 반사갓을 사용함으로써 램프에서 발하는 빛을 필요로 하는 작업면에 집중시켜 등기구의 효율을 높여주는 역할을 한다. Lamps generally have approximately 45% downward luminous flux and 55% upward luminous flux from the total luminous flux of the lamp. The lamp reflector ensures that the upward luminous flux generated by the lamps is not lost and is concentrated downward, so that the reflector itself does not save energy, but by using the optimum reflector, the lamp reflector concentrates on the work surface that needs the light emitted from the lamp. It serves to raise.
이와 같이 램프 반사갓은 전력을 직접적으로 사용하는 램프 및 안정기가 설치되는 등기구의 전력 소요량을 축소함으로써 간접적으로 전력 에너지 절약을 가능케 한다.In this way, the lamp reflector can indirectly save power by reducing the power requirements of the lamp and the ballast where the ballast is installed.
종래 램프에서 발생된 빛의 손실을 최소화하고 작업면으로의 조명 집중도를 향상시키기 위한 다양한 형태의 램프 반사갓이 개발되고 있으며, 일례로 도 1에는 공개실용신안 20-2009-0012566에 개시된 산업용 조명등의 다단 반사갓을 나타낸 것이다. 도 1을 참조하면, 종래 다단 반사갓은, 후방부는 지름이 작고 전방부는 지름이 큰 깔때기 형태를 형성하고 있으며, 서로 곡률을 달리하는 제1단 반사부(11)와 제2단 반사부(12) 및 제3단 반사부(13)가 후방부에서 전방부를 향하여 연속적으로 연장 설치된 구조로 이루어진 것으로, 서로 곡률을 달리하는 제1단 반사부(11)와 제2단 반사부(12) 및 제3단 반사부(13)가 집중 투광 범위내에서 크게 벗어나지 않도록 빛을 확산 투광시킴으로써 확산 투광 및 집중 투광이 동시에 이루어지도록 구성되어 있다. Various types of lamp reflectors have been developed to minimize the loss of light generated from the conventional lamps and to improve the concentration of lighting on the work surface. For example, FIG. 1 includes multiple stages of industrial lighting lamps disclosed in Korean Utility Model Model 20-2009-0012566. It is a reflection shade. Referring to FIG. 1, in the conventional multi-stage reflector, the rear portion has a small diameter and the front portion has a large funnel shape, and the first stage reflector 11 and the second stage reflector 12 having different curvatures from each other. And a third stage reflector 13 extending continuously from the rear portion toward the front portion, wherein the first stage reflector 11, the second stage reflector 12, and the third stage have different curvatures. However, the reflector 13 is configured to diffuse light and diffuse light simultaneously so as not to deviate significantly within the focused light emission range.
그러나 종래 다단 반사갓은 서로 다른 곡률로 형성된 다단의 반사부(11,12,13)가 연장 설치되어 램프에서 발생된 빛이 작업면을 향하도록 반사시킬 수 있는 이점은 있으나, 다단의 각 반사부(11,12,13)가 빛의 방향을 단지 하측으로 유도하는 반사 기능만을 포함하고 있어, 작업면에 균일한 조도의 빛을 고르게 분산시키는데 한계가 있다. However, the conventional multi-stage reflector has the advantage that the multi-stage reflecting portion (11, 12, 13) formed with different curvature is extended to reflect the light generated from the lamp toward the working surface, each of the multi-stage reflector ( 11, 12, 13 includes only a reflection function for directing the direction of light downward, there is a limit to evenly distribute the light of uniform illumination on the working surface.
한편, 분진의 발생하는 작업 환경에 설치될 경우에는 발생된 분진이 반사판에 흡착되어 반사효율이 낮아지게 되므로 반사판을 자주 청소해야 하는 관리상의 어려움이 있으며, 광속이 큰 램프를 사용할 경우에는 빛이 조사되는 영역과 그 주변 영역 간에 조도 차이가 커지게 되어 눈부심이 심해져 작업자가 눈의 피로를 쉽게 느끼게 되어 작업 능률이 저하되는 문제점이 있다.On the other hand, when it is installed in the working environment where dust is generated, the generated dust is absorbed by the reflector, which lowers the reflection efficiency. Therefore, there is a management difficulty in cleaning the reflector frequently. When using a lamp having a large luminous flux, light is emitted. There is a problem that the difference in illuminance between the area and the surrounding area becomes large, causing the glare to be severe, and the worker easily feels fatigue of the eye, thereby reducing work efficiency.

본 발명의 일실시예에 따른 램프 반사갓 장치(100)는, 메탈할라이드 램프, LED 램프, 세라믹 램프, 나트륨 램프, 무전극 램프 등의 광원(101)에서 발생된 빛을 작업면을 향하여 반사, 확산, 집중시키는 기능을 하며 상기 광원(101)을 둘러싸는 다단 구조의 1단 반사판(110)과, 2단 반사판(120) 및 3단 반사판(130)이 상측에서 하측으로 순차 연결 설치되고, 상기 광원(101)의 상측에는 안정기 등의 부품이 실장되며 전원에 연결되는 본체(102)가 결합되며, 상기 다단의 반사판(110,120,130)의 둘레에는 다단의 반사판(110,120,130)과 본체(102)에 고정되는 전등갓(103)이 설치된 구조로 이루어져 있다. Lamp reflector device 100 according to an embodiment of the present invention, the light generated from the light source 101, such as a metal halide lamp, LED lamp, ceramic lamp, sodium lamp, electrodeless lamp, reflected, diffused toward the working surface The first stage reflector 110, the second stage reflector 120, and the third stage reflector 130, which have a function of concentrating and surrounding the light source 101, are sequentially installed from an upper side to a lower side. The upper side of the 101 is a component such as a ballast is mounted and the main body 102 is connected to the power supply, the perimeter of the multi-stage reflector plate 110, 120, 130 and the lamp shade fixed to the multi-stage reflector plate (110, 120, 130) It consists of the structure in which 103 was provided.
상기 1단 반사판(110)은 광원(101)에서 발생된 빛을 하향으로 반사하고, 상기 2단 반사판(120)은 광속을 넓은 범위로 확산시키며, 상기 3단 반사판(130)은 확산된 광속을 그 저면의 개구부를 통해 작업면에 집중시키는 기능을 갖도록 구성되어 있으며, 상기 다단의 반사판(110,120,130)은 다음과 같은 구조로 이루어져 있다.The one-stage reflector 110 reflects the light generated from the light source 101 downward, the two-stage reflector 120 diffuses the luminous flux in a wide range, and the three-stage reflector 130 reflects the diffused luminous flux. It is configured to have a function of concentrating on the working surface through the opening of the bottom surface, the multi-stage reflector plate (110, 120, 130) has the following structure.
상기 1단 반사판(110)은 광원(101)으로부터 발생하는 상향의 광속을 하방향으로 반사시켜 광원(101)으로부터 상향으로 발산되는 일부의 빛이 조명으로 사용되지 못하고 손실되는 것을 방지하는 기능을 하는 것으로, 반사효율을 높일 수 있도록 알루미늄과 같은 반사율이 우수한 재질로 구성될 수 있으며, 그 내측면은 입사된 빛을 그대로 반사시키는 민자형의 평판 구조로 이루어져 있다. The first stage reflector 110 reflects an upward beam of light generated from the light source 101 in a downward direction to prevent a part of light emitted upward from the light source 101 from being used as illumination and being lost. It may be made of a material having excellent reflectance such as aluminum so as to increase reflection efficiency, and an inner surface thereof is made of a flat plate structure that reflects incident light as it is.
1단 반사판(110)으로 입사되어 반사되는 빛의 대부분은 하측의 개구부를 통해 작업면으로 직접 반사되고, 나머지 일부의 빛은 1단 반사판(110)의 하단에서 연장되도록 결합되는 2단 반사판(120)으로 반사된다.Most of the light incident and reflected by the first stage reflector 110 is reflected directly to the work surface through the lower opening, and the second portion of the second stage reflector 120 is coupled to extend from the bottom of the first stage reflector 110. ) Is reflected.
1단 반사판(110)과 광원(101)인 램프 사이의 간격은 적용되는 램프의 종류에 따라 20 ~ 50 mm의 범위로 설정될 수 있다. 즉, 1단 반사판(110)은 광원(101)의 빛을 반사시켜 하측으로 유도하는 역할을 하는 것으로, 1단 반사판(110)과 광원(101) 사이의 간격이 50 mm를 초과하여 너무 멀어지게 되면 빛의 반사효율이 떨어지게 되고, 1단 반사판(110)과 광원(101) 사이의 간격이 20 mm 미만으로 너무 가까워지게 되면 광원(101)의 열에 의해 1단 반사판(110)이 변형 및 탈색될 수 있기 때문이다.The interval between the first stage reflector 110 and the lamp which is the light source 101 may be set in a range of 20 to 50 mm depending on the type of lamp applied. That is, the one-stage reflector 110 serves to reflect the light of the light source 101 and guides it downward, so that the distance between the one-stage reflector 110 and the light source 101 exceeds 50 mm too far. When the reflection efficiency of the light is lowered, and the distance between the first stage reflector 110 and the light source 101 becomes too close to less than 20 mm, the first stage reflector 110 may be deformed and discolored by the heat of the light source 101. Because it can.
상기 2단 반사판(120)은 1단 반사판(110)의 하단으로부터 외측 하향으로 소정각도 경사지게 결합되며, 그 내측면에는 광원(101)으로부터 발광되어 입사되는 빛과, 상기 1단 반사판(110)에서 반사되어 입사되는 빛을 하방향으로 확산시키는 엠보싱(121)이 규칙적인 형상으로 형성된 것을 특징으로 한다.The two-stage reflecting plate 120 is coupled to be inclined at an angle downward from the bottom of the one-stage reflecting plate 110 to the outside downward, the inner surface of the light emitted from the light source 101 and incident from the first-stage reflecting plate 110 Embossing 121 for diffusing the reflected light incident downward is characterized in that formed in a regular shape.
1단 반사판(110)과 2단 반사판(120)의 연장선 사이에 형성되는 예각(θ1)은 15°이내의 범위로 형성되고, 2단 반사판(120)의 내측면에 형성되는 엠보싱(121)은 규칙적인 형상으로 이루어지고 오목한 형상으로 형성됨이 바람직하다. 이는 광원(101)으로부터 발산되어 2단 반사판(120)으로 입사되는 빛과, 1단 반사판(110)에서 반사되어 2단 반사판(120)으로 입사되는 빛이 하방향으로 확산되도록 유도하기 위한 것이다. An acute angle θ1 formed between the first stage reflecting plate 110 and the extension line of the second stage reflecting plate 120 is formed within a range of 15 °, and the embossing 121 formed on the inner side of the second stage reflecting plate 120 is It is preferably made in a regular shape and formed in a concave shape. This is for inducing the light emitted from the light source 101 to be incident on the two-stage reflector 120 and the light reflected from the first-stage reflector 110 and incident to the two-stage reflector 120 to be diffused downward.
도 5는 엠보싱이 형성된 2단 반사판에서 빛이 확산되는 원리의 설명도이다.5 is an explanatory view of the principle that light is diffused in the two-stage reflector plate embossed.
도 5(a)는 본 발명에 적용되는 엠보싱(121)이 2단 반사판(120)의 표면에서 함몰된 형상의 오목부(121a)가 격자 형태로 형성되고, 상기 오목부(121a) 사이에 연결부(121b)가 형성된 모습을 나타낸 것이다. 이 경우 상기 연결부(121b)로부터 오목부(121a)의 함몰된 깊이(L1)는 2 mm 이내로 형성되고, 도 3에 도시된 바와 같이 상기 오목부(121a)의 양측단 사이의 폭(L2)은 13 mm 이내로 형성됨이 바람직하다.5 (a) shows a recess 121a having a shape in which the embossing 121 applied to the present invention is recessed on the surface of the two-stage reflecting plate 120 is formed in a lattice shape, and a connection part is formed between the recesses 121a. It is shown that the (121b) is formed.
