Description

엘이디 투광기{A FLOODLIGHT WITH LED}LED Floodlights {A FLOODLIGHT WITH LED}

본 고안은 엘이디를 광원으로 이용하는 투광기에 관한 것으로서, 특히 하우징의 엘이디 설치공간 전방에 볼록렌즈가 반분된 형태의 하나의 하프볼록렌즈를 커버를 겸하여 설치함으로써 엘이디의 빛을 보다 넓은 영역으로 확산시킴과 아울러 부품수 및 조립공수를 획기적으로 감축시켜 생산성을 현저히 향상토록 하는 엘이디 투광기에 관한 것이다.The present invention relates to a light emitter using an LED as a light source, and in particular, one half-convex lens having a convex lens half-shaped in front of the LED installation space of the housing serves as a cover to diffuse the LED light to a wider area. In addition, the present invention relates to an LED light emitter to significantly improve the productivity by dramatically reducing the number of parts and assembly labor.

투광기는 가로등, 공원등, 터널등 등과 같이 주로 옥외 조명기구로 사용되는 것으로서, 옥외의 환경, 풍우, 먼지, 가스, 습기 등에 대한 내구성을 갖추는 한편 빛을 넓은 영역으로 확산 조사될 것이 요구된다.The light emitter is mainly used as an outdoor lighting fixture such as a street lamp, a park lamp, a tunnel lamp, etc., and is required to be diffused and irradiated with light in a wide area while having durability against outdoor environments, weather, dust, gas, and moisture.

한편, 엘이디(LED: Light Emitting Diode)는 종래의 광원에 비하여 소형이고 수명이 길뿐만 아니라 전기에너지가 빛에너지로 직접 변환되기 때문에 전력이 적게 소모되어 에너지 효율이 우수한 장점을 지니고 있어 이러한 엘이디를 광원으로 하는 다양한 투광기가 개발되고 있다.On the other hand, LED (Light Emitting Diode) is smaller and longer lifespan than conventional light sources, and because the electric energy is directly converted into light energy, it consumes less power and has excellent energy efficiency. Various light emitters have been developed.

엘이디를 광원으로 이용하는 투광기의 종래 기술은 도 4에 도시된 바와 같이, 엘이디 설치공간을 형성하며 엘이디 방열수단을 겸하는 하우징(110), 상기 하우징(110)에 설치되며 피씨비(133)에 실장되는 복수의 엘이디(131), 전원공급 구동부가 설치되는 서브하우징(120) 등으로 구성되어 있으며, 각각의 엘이디(131)에는 볼록렌즈(150)가 개별적으로 설치되고, 하우징의 엘이디 설치공간 입구에 투광커버(160)가 설치되었다As shown in FIG. 4, a conventional light emitter using an LED as a light source forms a LED installation space and serves as an LED heat dissipation means, a plurality of housings 110 installed in the housing 110 and mounted on the PC 133. LED 131, the sub-housing 120 is installed, such as the power supply drive unit, each LED 131, a convex lens 150 is installed separately, the floodlight cover at the entrance of the LED installation space of the housing 160 was installed

그런데 이와 같은 종래 기술은 각각의 엘이디(131)에 볼록렌즈(150)가 개별적으로 설치되고, 다시 투광커버(160)가 설치됨으로써 부품수가 많아지고 조립공수가 막대하게 낭비되어 제조원가를 상승시키는 문제점이 있었다.However, such a conventional technology has a problem in that the convex lens 150 is individually installed on each LED 131 and the floodlight cover 160 is installed again, thereby increasing the number of parts and enormous waste of assembly labor, thereby increasing manufacturing costs. .

또한, 볼록렌즈(150)가 각 엘이디(131)에 개별적으로 설치되므로 빛 직진성을 강화시켜 빛이 멀리 나가는 반면에 확산되지 못하여 투광기의 조사영역이 넓지 못한 문제점이 있었다.In addition, since the convex lens 150 is individually installed on each LED 131, the light straightness is enhanced to prevent the light from diffusing while the light is emitted far.

본 고안은 상기한 문제점을 해소하기 위하여 안출된 것으로서,The present invention has been devised to solve the above problems,

본 고안의 목적은 엘이디 설치공간 전방에 볼록렌즈가 반분된 형태의 하나의 하프볼록렌즈를 설치함으로써 다수 엘이디 빛의 확산 굴절을 유도하여 빛이 보다 넓은 영역으로 확산조사되고 이에 따라 옥외설치용으로서의 품질특성이 현저히 향상되도록 하는 엘이디 투광기를 제공함에 있다.The purpose of the present invention is to install a half-convex lens with a half-convex lens in front of the LED installation space, which induces the diffraction and refraction of a large number of LED lights. It is to provide an LED light emitter so that this is significantly improved.

본 고안의 다른 목적은 하나의 렌즈가 다수 엘이디의 빛을 확산굴절시키고 엘이디 설치공간의 커버를 겸하도록 하여 부품수 및 조립공수를 획기적으로 감축시켜 생산성을 현저히 향상토록 하는 엘이디 투광기를 제공함에 있다.Another object of the present invention is to provide an LED light emitter to significantly improve the productivity by significantly reducing the number of parts and assembly labor by diffusing and refracting the light of a plurality of LEDs and the cover of the LED installation space.

There is an excellent effect that the quality characteristics are significantly improved.

또한, 하나의 렌즈가 다수 엘이디의 빛을 확산굴절시키고 엘이디 설치공간의 커버를 겸하도록 하여 부품수 및 조립공수를 획기적으로 감축시켜 생산성을 현저히 향상시키는 뛰어난 효과가 있다.In addition, one lens diffuses and refracts the light of a plurality of LEDs, and serves as a cover of the LED installation space, thereby significantly reducing the number of parts and assembly labor, thereby having an excellent effect of significantly improving productivity.

이하, 본 고안의 엘이디 투광기에 대한 실시예를 첨부도면을 참조하여 보다 상세히 설명한다.Hereinafter, an embodiment of an LED light emitter of the present invention will be described in more detail with reference to the accompanying drawings.

도 1은 본 고안에 따른 일 실시예의 구성을 보이는 사시도, 도 2는 도 1의 단면도이다. 도 1 및 도 2에 도시된 바와 같이, 본 고안에 따른 일 실시예의 엘이디 투광기(1)는 엘이디 설치공간(11)을 형성하며 엘이디 방열수단을 겸하는 하우징(10), 상기 하우징(10)에 설치되며 피씨비(33)에 실장되는 복수의 엘이디(31) 및 반사판(40)을 포함하는 엘이디 투광기에 있어서, 상기 하우징(10)은 엘이디 설치공간(11) 전방에 단차부(13)를 형성하고, 상기 하우징(10)은 엘이디 설 치공간(11) 전방에 단차부(13)를 형성하고, 상기 단차부(13)에 엘이디의 빛을 확산시키는 하나의 렌즈(50)가 커버를 겸하여 설치되는 것이다.1 is a perspective view showing the configuration of an embodiment according to the present invention, Figure 2 is a cross-sectional view of FIG. As shown in Figure 1 and 2, the LED floodlight (1) of the embodiment according to the present invention forms an LED installation space 11 and serves as the LED heat dissipation means 10, the installation in the housing 10 And a plurality of LEDs 31 and a reflector plate 40 mounted on the PC 33, the housing 10 forms a step portion 13 in front of the LED installation space 11, The housing 10 is a step (13) is formed in front of the LED installation space 11, the one lens 50 for diffusing the LED light in the step portion 13 is installed as a cover. .

상기 렌즈(50)는 볼록렌즈가 반분된 형태로 내면(51)은 평탄 형성되고 외면(53)이 볼록형성된 하프볼록렌즈로 이루어짐이 바람직하다.The lens 50 may be formed of a half-convex lens having a convex lens half-divided, and having an inner surface 51 formed flat and an outer surface 53 convex.

여기서, 하프볼록렌즈 대신 하프오목렌즈를 사용할 경우, 빛의 확산성은 매우 좋으나 조도가 현저히 떨어지는 단점이 있다.In this case, when the half convex lens is used instead of the half convex lens, the light diffusing property is very good but the illuminance is remarkably inferior.

또한, 상기 하우징(10)은 방열면적 확장을 위하여 외표면이 요철형성됨이 바람직하다. In addition, it is preferable that the outer surface of the housing 10 is unevenly formed to expand the heat dissipation area.

상기 하우징(10)의 외표면에는 방열핀이 둘러 형성되어도 무방하다.The heat dissipation fin may be formed around the outer surface of the housing 10.

또한, 상기 하우징(10) 후방에는 전원구동부(35)가 설치되는 서브하우징(20)이 구비되며, 도 3에 도시된 바와 같이, 상기 서브하우징(20)을 통하여 하나 이상의 투광기가 일체로 연결형성될 수도 있다. 도면 중 미설명 부호 '25'는 패킹이다.In addition, a rear housing 20 is provided with a sub-housing 20 in which a power driver 35 is installed. As shown in FIG. 3, one or more light emitters are integrally connected through the sub-housing 20. May be In the drawings, reference numeral 25 denotes a packing.

이와 같은 구성을 지닌 본 고안에 따른 엘이디 투광기(1)의 작용상태를 살펴본다.Looking at the working state of the LED floodlight (1) according to the present invention having such a configuration.

본 고안은 하우징(10)의 엘이디 설치공간 전방(11)에 하나의 렌즈(50), 즉 볼록렌즈가 반분된 형태의 하프볼록렌즈를 설치함으로써 엘이디의 빛을 확산시킨다.The present invention spreads the light of the LED by installing a half lens of the lens 50, that is, a half-convex lens in which the convex lens is half divided in front of the LED installation space 11 of the housing 10.

엘이디(31)의 빛이 하프볼록렌즈의 내면(51)인 평탄면으로 입사되므로 볼록형성된 외면(53)에서 확산 굴절이 발생되는 것이다.Since the light of the LED 31 is incident on the flat surface, which is the inner surface 51 of the half convex lens, diffused refraction occurs in the convex outer surface 53.

따라서, 투광기가 조도를 훼손하지 않으면서 빛이 보다 넓은 영역으로 확산조사되어 가로등이나 공원등과 같은 옥외설치용으로서의 품질특성이 현저히 향상된다.Therefore, the light is diffused and irradiated to a wider area without compromising illuminance, thereby significantly improving the quality characteristics for outdoor installation such as a street lamp or a park.

또한, 하나의 하프볼록렌즈가 다수 엘이디(31)의 빛을 굴절시키고 엘이디 설치공간의 커버를 겸하므로 종래기술에 비하여 부품수 및 조립공수를 획기적으로 감축시켜 생산성을 현저히 향상시키고 제조원가를 감축시킨다.In addition, since one half-convex lens refracts the light of the plurality of LEDs 31 and serves as a cover of the LED installation space, it significantly reduces the number of parts and assembly labor compared with the prior art, thereby significantly improving productivity and reducing manufacturing costs.
