Abstract

A high voltage and efficiency light for a tunnel is provided to improve durability and continuously maintain high illuminance by preventing inflow of dust or moisture through a packing member between a cover and a main body. A high voltage and efficiency light for a tunnel includes a cover(5), a main body(4), a knob(6), a fold type link, an elastic support(9), an embossing reflection plate(10), a rubber packing(11), a fixing hook(12), and a suspension loop(13). The knob is installed on the cover. The fold type link controls an open angle of the cover between the main body and the cover and supports load of the cover to the main body by being connected so that the main body and the cover are rotated. A high voltage lamp(1) mounted on the main body is supported by the elastic support. The embossing reflection plate scatters the light of the lamp on a rear surface of the high voltage lamp. The rubber packing is installed between the cover and the main body to block inflow of foreign materials. The cover and the main body are coupled by the fixing hook and the suspension loop.

고압 고효율 터널등{A HIGH VOLTAGE, HIGH EFFICIENCY LIGHT FOR TUNNEL}High-pressure high-efficiency tunnel light {A HIGH VOLTAGE, HIGH EFFICIENCY LIGHT FOR TUNNEL}

본 발명은 터널의 벽면에 설치하여 터널 내부를 조명하는 터널등에 관한 것으로, 특히 램프를 안전하게 지지할 수 있고, A/S 작업을 편리하게 할 수 있으며, 터널의 조명효과를 높일 수 있게 한 고압 고효율 터널등에 관한 것이다. The present invention relates to a tunnel and the like installed on the wall of the tunnel to illuminate the inside of the tunnel, in particular, it is possible to safely support the lamp, to facilitate the A / S work, high pressure high efficiency to increase the lighting effect of the tunnel It is about tunnels.

일반적으로 산야가 많은 우리나라의 실정상 도로를 만들 때 필연적으로 많은 터널이 만들어지게 되는데, 이러한 터널에는 조명을 위해 터널등이 설치된다.In general, many tunnels are inevitably created when real roads in Korea have many mountains and mountains, and tunnels are installed for lighting.

이러한 터널등은 터널 벽면에 고정되는 본체와 상기 본체에 결합되는 커버로 이루어지면서, 상기 본체에 램프와 제어기구 등이 설치된 구조로 이루어져 있다.Such a tunnel is made of a main body fixed to the tunnel wall and a cover coupled to the main body, and has a structure in which a lamp and a control mechanism are installed on the main body.

그런데 기존의 일반적인 터널등은 수리나 A/S를 위해 커버를 열었을 때, 커버가 본체에서 완전히 분리되기 때문에 커버를 별도로 지면에 내려 놓거나 들고 있어야 하는 불편함이 있고, 본체의 내부에 설치된 램프가 흔들리기 때문에 램프의 고장이 잦아 자주 교체해 주어야 하는 문제점이 있었으며, 램프의 뒷면에 설치된 반사판의 반사율이 낮아 램프의 불빛은 효과적으로 분산시켜 주지 못하는 단점이 있는 한편, 본체와 커버 사이의 틈새를 통하여 먼지나 습기 등의 이물질이 터널등의 내부로 유입되어 램프의 수명이 짧다는 등의 문제점이 있었다.By the way, when the conventional tunnel is opened for repair or after-sales service, the cover is completely separated from the main body, which is inconvenient to put the cover on the ground or lift it separately, and the lamp installed inside the main body shakes. Because of this problem, there is a problem that the lamp needs to be replaced frequently, and the reflector installed on the back of the lamp has a low reflectance, which makes it difficult to effectively disperse the lamp light. There is a problem that foreign matters such as the lamp is introduced into the tunnel, such that the life of the lamp is short.

이에 본 발명은 상기한 바와 같은 종래의 터널등에 따른 문제점을 해결하기 위해 발명된 것으로서, 특히 램프를 안전하게 지지할 수 있고, A/S 작업을 편리하게 할 수 있으며, 터널의 조명효과를 높일 수 있게 한 고압 고효율 터널등을 제공하는데 그 목적이 있다.Accordingly, the present invention has been invented to solve the problems caused by the conventional tunnels as described above, in particular, it is possible to safely support the lamp, to facilitate the A / S work, and to increase the lighting effect of the tunnel The purpose is to provide a high-pressure high-efficiency tunnel.
