본 발명은 엘이디(LED:Light Emitting Diode)용 렌즈장치에 관한 것으로, 더욱 상세하게는 2줄×17개의 렌즈부가 형성된 패널(Panel)형태의 렌즈가 회로기판상에 장착되도록 함으로써 회로기판상에 연속적으로 설치된 다수개의 엘이디에 대한 렌즈의 장착작업성 및 생산성을 획기적으로 향상시킬 수 있도록 하고, 엘이디로부터 발생된 빛이 렌즈의 표면에 도달되기 전단계에서 전(全)방향으로 다수회 반사된 후 렌즈의 표면에서 확산·조사(照射)되도록 함으로써 빛의 확산성을 크게 향상시킬 수 있도록 한 엘이디용 렌즈장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lens device for an LED (Light Emitting Diode), and more particularly, a panel-type lens in which two rows of 17 lens portions are formed is mounted on a circuit board so as to be continuously mounted on the circuit board. It is possible to drastically improve the workability and productivity of the lens for a plurality of LEDs installed in the system.The light emitted from the LEDs is reflected a plurality of times in all directions before reaching the surface of the lens. The present invention relates to an LED lens device capable of greatly improving the diffusivity of light by being diffused and irradiated on a surface.

일반적으로, 가로등은 실외에서 도로가 또는 공원 등에 설치되어 어둠을 밝히는 역할을 하는 것으로, 근래에는 단순히 어둠을 밝히는 용도에서 운전자의 안전운행과 보행자의 안전한 보행등으로 다양하게 활용되고 있다.In general, street lights are installed in roads or parks outdoors to illuminate the darkness, and in recent years, street lights have been used in various ways, such as simply driving the lights, driving safety and pedestrians.

이와 같은 조명등의 광원(光源)으로서 종래에는 형광등이나 백열전구 또는 할로겐등이 주로 사용되었는데, 이 경우 상대적으로 전력의 소모가 심하고, 수명이 짧은 반면 조도가 낮다는 문제가 있다.Conventionally, a fluorescent lamp, an incandescent lamp, or a halogen lamp is mainly used as a light source of such a lighting lamp. In this case, there is a problem in that power consumption is relatively high, and the life is short, while the illuminance is low.

이에 따라 최근에는 이와 같은 형광등이나 백열등 또는 할로겐등 같은 기존의 광원 대신에 상대적으로 오랜 시간 동안 사용할 수 있고, 전력 소모량이 매우 적으며, 밝기가 매우 밝은 것은 물론, 지연시간 없이 순간 점등되고 안전성이 뛰어나며, 다양한 색상으로 연출가능한 엘이디(LED)가 회로기판에 장착된 형태에서 조명등의 광원으로 적용되고 있다.As a result, it can be used for a relatively long time instead of a conventional light source such as a fluorescent lamp, an incandescent lamp or a halogen lamp, has a very low power consumption, a very bright brightness, instantaneous lighting without safety, and excellent safety. LEDs, which can be produced in various colors, are applied to light sources in the form of being mounted on circuit boards.

그러나, 엘이디는 셀(Cell)당 밝기에 한계가 있기 때문에 원하는 조도를 얻기 위해서는 다수개의 엘이디를 직렬 또는 병렬로 설치하여 사용해야 되고, 백열등이나 형광등에 비하여 상대적으로 빛의 직진성이 강한 반면, 확산성은 떨어지기 때문에 중심에서 벗어나면 어두워지는 현상이 발생된다는 단점이 있다. However, since LEDs have a limitation in brightness per cell, a plurality of LEDs must be installed in series or in parallel in order to obtain a desired illuminance. Compared to incandescent or fluorescent lamps, the linearity of light is relatively high, but the diffusion is inferior. Because it loses, the phenomenon that becomes dark when it is out of the center has a disadvantage.

이에 따라, 최근 엘이디가 적용되는 조명등장치에서는 회로기판에 설치된 엘이디의 전면에 별도의 렌즈를 씌워 엘이디로부터 발생된 빛이 확산되도록 하는 방법이 시도되고 있다.Accordingly, recently, in a lamp device to which an LED is applied, a method of applying a separate lens to the front surface of an LED installed on a circuit board to diffuse light generated from the LED is attempted.

도 1은 일반적인 엘이디용 렌즈의 설치상태를 나타내는 확대 단면도이다.1 is an enlarged cross-sectional view showing an installation state of a general LED lens.

상기 도 1에 따르면, 종래 엘이디용 렌즈(10)에는 이면(裏面)의 중심부에 회로기판(11)상의 엘이디(12)가 끼워지는 엘이디 끼움홈(13)이 형성되고, 표면에는 상기 엘이디(12)로부터 발생된 빛을 확산시키기 위한 돔(Dome)형 반사부(14)가 형성되며, 이면의 가장자리에는 회로기판(11)에 끼워지는 복수개의 장착핀(15)이 돌출되게 형성된 구조로 이루어진다.According to FIG. 1, an LED fitting groove 13 into which an LED 12 on a circuit board 11 is fitted is formed at a central portion of a conventional LED lens 10, and the LED 12 is formed on a surface of the LED lens 10. A dome-shaped reflector 14 is formed to diffuse the light generated from the light source, and a plurality of mounting pins 15 fitted to the circuit board 11 protrude from the edge of the back surface.

그러나, 이와 같은 종래의 엘이디용 렌즈(10)는 그 크기가 매우 작고 표면이 돔형상으로 이루어져 손으로 잡기 불편하한 것은 물론, 상기 회로기판(11)상에 설치된 다수개의 엘이디(12) 하나 하나에 끼워 맞추어야 하기 때문에 작업성이 매우 불량하다는 문제가 있다.However, the conventional LED lens 10 is very small in size and has a dome shape, which is inconvenient to hold by hand, and a plurality of LEDs 12 installed on the circuit board 11. There is a problem that workability is very poor because it must be fitted.

또, 상기 엘이디(12)로부터 발생된 빛이 렌즈체를 투과한 후 표면의 돔형 반사부(14)에서만 확산·반사되기 때문에 빛의 확산효율이 그다지 높지 않다는 문제가 있다. In addition, since the light generated from the LED 12 is diffused and reflected only in the domed reflector 14 on the surface after passing through the lens body, there is a problem that the light diffusion efficiency is not so high.

본 발명은 이와 같은 종래의 문제점을 해결하기 위한 것으로, 그 목적은 2줄×17개의 렌즈부가 형성된 패널(Panel)형태의 렌즈가 회로기판상에 장착되도록 함으로써 회로기판상에 연속적으로 설치된 다수개의 엘이디에 대한 렌즈의 장착작업성을 획기적으로 향상시킬 수 있도록 한 새로운 엘이디용 렌즈장치를 제공하는 것이다.SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and an object thereof is to provide a plurality of LEDs continuously installed on a circuit board by mounting a panel-type lens on a circuit board having two rows of 17 lens parts. It is to provide a new LED lens device that can significantly improve the mounting workability of the lens for the.

본 발명의 다른 목적은 엘이디로부터 발생된 빛이 렌즈의 표면에 도달되기 전단계에서 전(全)방향으로 다수회 반사된 후 다시 렌즈의 표면에서 확산·반사되도록 함으로써 빛의 확산효율을 크게 향상시킬 수 있도록 한 새로운 엘이디용 렌즈장치를 제공하는 것이다. Another object of the present invention can greatly improve the light diffusion efficiency by allowing the light generated from the LED to be reflected and reflected on the front surface of the lens many times before reaching the surface of the lens. It is to provide a new lens device for the LED.

상기의 목적을 달성하기 위하여, 본 발명은 회로기판상에서 가로 및 세로방향을 따라 연속적으로 설치된 다수개의 엘이디를 덮을 수 있는 크기를 갖는 단일의 패널상에 2줄×17개의 렌즈부가 형성되고, 상기 패널의 길이방향 중심선상에는 상기 회로기판상에 패널을 고정·장착시키는 스크류가 끼워질 수 있도록 하기 위한 다수개의 스크류 삽입보스가 일정 간격으로 형성된 특징을 갖는다.In order to achieve the above object, the present invention is formed on the circuit board is formed on a single panel having a size that can cover a plurality of LEDs continuously installed along the horizontal and vertical direction, two rows x 17 lens parts are formed, A plurality of screw insertion bosses are formed at regular intervals on the longitudinal center line of the circuit board to allow the screws to fix and mount the panel on the circuit board.

본 발명에서 상기 패널상에 형성되는 각각의 렌즈부의 이면 중심부에는 회로기판상에 설치된 엘이디가 끼워지는 엘이디 끼움홈이 형성되고, 상기 엘이디 끼움홈의 내주면에는 서로 다른 기울기를 갖는 다수개의 경사면이 형성되는 한편, 상기 렌즈부 표면의 중심부에는 수평의 제1반사면이 형성되고, 렌즈부 표면의 가장자리에는 둥글게 곡면진 제2반사면이 형성된 특징을 갖는다.In the present invention, an LED fitting groove into which an LED installed on a circuit board is fitted is formed at the center of the rear surface of each lens unit formed on the panel, and a plurality of inclined surfaces having different inclinations are formed on the inner circumferential surface of the LED fitting groove. Meanwhile, a horizontal first reflection surface is formed at the center of the lens portion surface, and a second curved reflection surface is formed at the edge of the lens portion surface.

본 발명을 적용하면, 2줄×17개의 렌즈부가 형성된 패널(Panel)형태의 렌즈가 회로기판상에 장착되면서 한번에 2줄×17개의 엘이디에 렌즈가 장착되기 때문에 회로기판상에 연속적으로 설치된 다수개의 엘이디에 대한 렌즈의 장착작업성을 획기적으로 향상되어 생산성이 크게 향상된다는 효과가 있다.According to the present invention, since a lens having a panel form having two rows of 17 lenses is mounted on a circuit board, the lenses are mounted on the circuit board at a time, so that a plurality of lenses are continuously installed on the circuit board. The mounting workability of the lens on the LED is greatly improved, and the productivity is greatly improved.

또, 엘이디로부터 발생된 빛이 렌즈부의 표면에 도달되기 전단계에서 엘이디끼움홈의 내주면에 형성된 기울기가 다른 다수개의 경사면에서 전(全)방향으로 다수회 반사된 후 다시 렌즈의 표면 및 가장자리에서 확산되면서 조사되기 때문에 빛의 확산성이 크게 향상된다는 효과가 있다.In addition, before the light generated from the LED reaches the surface of the lens part, the inclination formed on the inner circumferential surface of the LED fitting groove is reflected a plurality of times in all directions from different inclined surfaces, and then diffuses again from the surface and the edge of the lens. Since it is irradiated, there is an effect that the light diffusion is greatly improved.
