Description

기능성 전기 변색 아이웨어Functional electrochromic eyewear
본 발명은 기능성 전기 변색 아이웨어에 관한 것으로, 더욱 상세하게는 LCD(Liquid Crystal Display)를 적용하여 렌즈의 투과율을 전기적으로 조정하는 기능성 전기 변색 아이웨어에 관한 것이다.The present invention relates to a functional electrochromic eyewear, and more particularly, to a functional electrochromic eyewear for electrically adjusting the transmittance of a lens by applying a liquid crystal display (LCD).
본 발명에서 아이웨어(eyewear)라 함은, 스키 고글, 스포츠 글라스, 보안안경, 선글라스 등 눈에 착용하는 렌즈가 있는 모든 제품을 의미한다.In the present invention, the term "eyewear" means all products having lenses to be worn on the eyes such as ski goggles, sports glasses, safety glasses, sunglasses, and the like.
일반적으로 아이웨어 제품은 밝은 태양빛의 노출을 피하기 위하여, 렌즈의 투과율을 낮춘 렌즈를 사용하고 있다. 예로서, 렌즈를 착색을 하여 사용하기도 하고, 렌즈 표면 미러증착을 하여 빛의 투과율을 낮춰, 눈부심을 방지하고 있다.In general, eyewear products use a lens with a lower transmittance of the lens to avoid exposure to bright sunlight. For example, the lens may be colored, and the lens surface mirror deposition may be used to lower the transmittance of light to prevent glare.
그런데, 고정된 투과율은 밝은 날에는 필요하지만, 어두운 날이나 저녁에는 낮은 투과율로 인해 주변 사물이 잘 보이지 않는 단점이 있다. 이런 단점을 개선하고자 변색(photochromic) 렌즈를 사용하는 기술이 개발된 바 있다.By the way, a fixed transmittance is necessary on a bright day, but on a dark day or in the evening, due to low transmittance, there is a disadvantage that the surrounding objects are hard to see. In order to remedy this disadvantage, a technique using a photochromic lens has been developed.
변색 물질은, 태양빛이 강하게 노출시, 더욱 상세하게는 UV 강도가 세지면 도 1에 도시된 바와 같이 분자 구조가 활성화 되면서 투과율이 변화게 되는 성질이 있다. 이 물질을 렌즈에 함침 시키거나, 코팅 형태로 렌즈 표면에 막을 형성해 놓으면, 빛의 밝기(UV 세기)에 따라 렌즈가 어두워지고 밝아지는 제품으로 적용하고 있다.The discolored material is strongly exposed to sunlight, more specifically, when the UV intensity is strong, as shown in Figure 1 has the property that the transmittance is changed while the molecular structure is activated. If this material is impregnated into the lens or a film is formed on the surface of the lens, the lens becomes dark and bright depending on the brightness (UV intensity) of the light.
그러나, 이와 같은 종래기술에 따른 변색 기술은 다음과 같은 문제점이 있다.However, the discoloration technology according to the prior art has the following problems.
우선 변색 되는 정도, 즉 변색량을 사용자가 조작할 수 없다. 따라서, 사용자에 따라 밝은 날에도 좀 더 밝은 렌즈를 선호하는 경우가 있지만 종래의 변색렌즈는 미리 설정된 변색량을 변경할 수 없는 문제점이 있었다.First, the degree of discoloration, that is, the amount of discoloration cannot be manipulated by the user. Therefore, although a user may prefer a brighter lens even on a bright day, the conventional color changing lens has a problem in that it cannot change a predetermined amount of color change.
또한, 변색렌즈는 투과율이 변화는 시간이 3분 ~10분까지 오래 걸린다. 즉, 이로 인해 외부에서 실내로 이동하면, 렌즈가 어두운 상태가 상당시간 유지되어 사용에 불편한 점이 있다.In addition, the change in transmittance of the color changing lens takes a long time from 3 minutes to 10 minutes. That is, when moving from the outside to the indoors due to this, the dark state of the lens is maintained for a long time there is an inconvenience in use.
그리고, UV에 반응하는 제품임으로, 실내조명에서도 일정 부분 반응하게 되는 문제점이 있었다.And, because it is a product that reacts to UV, there was a problem that will react in part even in indoor lighting.
본 발명은 상술한 종래기술의 문제점을 극복하기 위한 것으로서, LCD를 적용하여 렌즈의 변색 속도 및 변색량을 사용자에 의하여 조작할 수 있고, UV에 반응하지 않고 조도에 따라 렌즈의 투과율을 전기적으로 조정하여 더욱 정확한 변색 기능을 수행하는 기능성 전기 변색 아이웨어를 제공하는 데에 그 목적이 있다.The present invention is to overcome the above-mentioned problems of the prior art, by applying an LCD can be manipulated by the user the color change speed and the amount of color change of the lens, and electrically adjust the transmittance of the lens according to the illumination without reacting to UV The purpose is to provide a functional electrochromic eyewear that performs a more accurate color change function.

즉, 본 발명은 상기 LCD부(200)의 편광도(Polar Efficiency )를 65% ~70%를 유지하면서, 투과율 55% 이상을 유지하도록 제어한다.That is, the present invention controls the polarization degree (Polar Efficiency) of the LCD unit 200 to maintain 55% or more while maintaining 65% to 70%.
단일 편광 필름을 상기와 같이 제조시, 제품의 초기 투과율(off)을 43% 이상 유지하며, 차단 투과율(ON)을 15% 이하로 유지하게 할수 있다.When manufacturing a single polarizing film as described above, it is possible to maintain the initial transmittance (off) of the product 43% or more, and to maintain the blocking transmittance (ON) of 15% or less.
또한, 렌즈(100) 양면에 LCD부(200)를 형성하고, 앞뒤 편광 필름의 편광도를 서로 다르게 조합하여, 초기 투과율을 일정수준 올리면서, 차단 투과율을 더 낮추는 제어도 본 발명의 요지에 따라 적용가능 하다.In addition, by forming the LCD unit 200 on both sides of the lens 100, by combining the polarization degree of the front and rear polarizing film differently, the control to further lower the blocking transmittance while raising the initial transmittance to a certain level is also applied according to the gist of the present invention. It is possible.
예를 들어, 제어부(400)의 제어를 통하여, 한쪽 면의 편광 필름의 편광도를99%를 유지하고, 또 다른 편광 필름편광도는 70% 정도를 유지하면, 40%에서 8% 정도의 투과율 변화를 구현함으로써, 종래 문제점을 해결하면서 렌즈의 변색 속도 및 변색량을 사용자에 의하여 신속히 조작할 수 있고, UV에 반응하지 않고 조도에 따라 렌즈(100)의 투과율을 전기적으로 조정하여 더욱 정확한 변색 기능을 수행할 수 있다.For example, if the polarization degree of one side of the polarizing film is maintained at 99% and the other polarization film polarization degree is maintained at about 70% through the control of the control unit 400, the transmittance change of about 40% to 8% is changed. By implementing the above, the color change speed and the amount of color change of the lens can be quickly manipulated by the user while solving the conventional problem, and the color transmittance of the lens 100 is electrically adjusted according to the illumination without reacting to UV to perform a more accurate color change function. can do.
또한, 본 발명은 최적 컬러구현을 위하여, 편광 필름의 PVA(편광자)는 염료 타입으로 구현하여, 렌즈(100)에서 필요한 색감을 염료로써 구현할 수도 있다.In addition, the present invention may implement a PVA (polarizer) of the polarizing film in the dye type, for the optimal color implementation, to realize the color required by the lens 100 as a dye.
일반적인 LCD는 35%이하 ~ 1%이하의 투과율 변화를 가지지만, 본 발명은 오프시 투과율을 밝게 하여, 어두운 곳에서도 사용이 가능하며, 온시 일반 선글라스 정도의 투과율을 가지는 특징이 있다.The general LCD has a transmittance change of less than 35% to less than 1%, but the present invention brightens the transmittance when turned off, so that it can be used even in a dark place, and has a transmittance of about normal sunglasses when turned on.
또한, 본 발명은 도 5에 도시된 바와 같이, 본 발명의 다른 실시예로서 다양한 선글라스 형태를 나타낼 수 있다.In addition, the present invention may represent various sunglasses forms as another embodiment of the present invention, as shown in FIG.
