차량용 엘이디램프의 광확산커버{Light Diffusion Cover of LED lamp for vehicles}Light Diffusion Cover of LED lamp for vehicles}

본 고안은 차량용 엘이디램프의 광확산커버에 관한 것으로, 더욱 상세하게는 엘이디모듈로 형성된 차량용 엘이디램프로부터 발생되는 빛을 확산시켜 일반 조명등과 유사한 빛의 확산 각을 갖도록 하여 광원으로써의 효율과 시각적 안정감을 줄 수 있는 차량용 엘이디램프의 광확산커버에 관한 것이다.
The present invention relates to a light diffusion cover of an LED lamp for a vehicle, and more particularly, to diffuse light generated from the LED lamp for a vehicle formed by the LED module to have a light diffusion angle similar to that of a general lighting lamp, so as to provide efficiency and visual stability. The present invention relates to a light diffusion cover of an LED lamp for a vehicle.

일반적으로, 조명등은 광원으로부터의 빛을 반사?굴절?투과시켜서 주변환경의 시인성을 확보하고, 생활의 편리성을 도모하기 위한 것으로, 백열등, 형광등, 할로겐등이 주로 이용되고 있다.
Generally, incandescent lamps, fluorescent lamps, and halogen lamps are mainly used to illuminate, reflect, and transmit light from a light source to secure visibility of the surrounding environment, and to facilitate life.

여기서, 종래의 백열등은 점등을 위한 동작 속도가 빠른 장점이 있으나 필라멘트를 가열하여 빛을 발생시키는 방식으로 효율성이 떨어지는 단점이 있으며, 형광등은 형광체를 발광시키는 방식으로 빛을 발생시키는 것으로 백열등에 비해 전력소모가 적은 장점이 있으나 내부에 형광체로 사용되는 수은(Ag)이 환경 유해물질이어서 그 적용범위가 줄어들고 있는 추세이다.
Here, the conventional incandescent lamp has the advantage that the operation speed for the lighting is fast, but the efficiency is inferior in the method of heating the filament to generate light, the fluorescent lamp is to generate light by the method of emitting a phosphor to power than incandescent lamp There is a small consumption advantage, but the mercury (Ag) used as a phosphor in the environment is a harmful environment, the scope of application is decreasing.

따라서, 최근에는 종래 조명등으로 사용하던 백열등이나 형광등 등의 조명등을 대신하여 엘이디(LED)를 이용한 조명기술이 크게 발전하고 있으며, 이를 이용한 기술적 연구가 많이 행해지고 있다. 이러한, 엘이디(LED)는 수명이 길고 전력소모량이 적으면서 색상 구현능력이 뛰어나서 광도와 효율이 높은 특성이 있다.
Therefore, in recent years, lighting technology using LED (LED) has been greatly developed in place of incandescent lamps or fluorescent lamps, which have been used as conventional lighting lamps, and many technical studies using the same have been conducted. Such LEDs have long characteristics, high power consumption and low color consumption, and have high brightness and efficiency.

그러므로, 이와 같은 엘이디(LED)를 이용한 제품이 크게 증가하고 있으며, 조명등 시장에서도 엘이디(LED)를 이용하는 기술 개발이 많이 이루어지고 있는 추세이고, 엘이디(LED)를 이용한 조명은 일반 형광등에 비해 수명이 3배 이상 길며, 밝기에 있어서도 형광등에 준하는 밝기를 가지므로 차기 조명소재로 우수한 성능을 가지고 있다.
Therefore, products using LEDs are increasing significantly, and the development of technology using LEDs is being made in the lighting market, and lighting using LEDs has a longer lifespan than general fluorescent lamps. It is more than 3 times longer and has the same brightness as the fluorescent lamp in terms of brightness, and has excellent performance as the next lighting material.

그러나, 엘이디(LED)는 광원에서 밝기는 뛰어나지만 광원이 작고 시야각이 크게 작아 조명으로 사용하기에는 어려움이 있었다. 따라서, 조명등으로 엘이디(LED)의 사용범위가 점차 증가하고 있는 추세에 있는 상황에서 엘이디(LED)를 이용하여 조명등의 특징인 빛의 확산성을 개선시켜, 엘이디(LED)를 이용하여 조명등으로 적극 사용할 수 있도록 하는 기술적 개발의 필요성이 요구되고 있다.
However, LED (LED) has excellent brightness in the light source, but the light source is small and the viewing angle is large, it is difficult to use as lighting. Therefore, in a situation where the use range of LEDs is gradually increasing as a lamp, LED is used to improve the light diffusivity, which is a characteristic of the lamp, and LED is used as a lamp. There is a need for technical development to make it available.

따라서, 본 고안은 상술한 바와 같은 문제점을 해결하기 위해 안출한 것으로, 엘이디로부터 발생되는 빛을 보다 효과적으로 확산시켜 확산각을 크게 형성하고, 이를 통해 광원에 의한 주변 환경의 시인성과 시각적 안정감은 물론 보다 광원을 효율적으로 활용이 가능하여 다수의 엘이디램프를 적용하지 않고도 조명이 가능함으로써, 에너지 절약이 가능한 차량용 엘이디램프의 광확산커버를 제공하는 데 그 목적이 있다.
