이와 같은 실시예의 잔광 휘도를 측정한 결과는 표 1과 같다.Table 1 shows the results of measuring the afterglow luminance of the example.

상기한 결과에서 보는 바와 같이, 비교예 1에 의해 제조된 축광성 발광시트는 코팅 표면이 매끄럽지 않아 쉽게 오염이 되기 때문에 장기간 사용하기 어렵고, 시간이 경과하면서 잔광휘도가 현저하게 낮아지는 문제가 있다.As can be seen from the above results, the photoluminescent light emitting sheet prepared by Comparative Example 1 has a problem in that it is difficult to use for a long time because the coating surface is not smooth and easily contaminated, and the afterglow luminance is significantly lowered over time.

본 발명에 의한 실시예 1은 코팅 표면의 요철부가 없어짐으로써 장기간 사용을 하더라도 오염 발생이 되지 않으며, 시간이 경과한 후에 휘도가 우수함을 알 수 있고, 실시예 2는 시간 경과에 따라 잔광휘도가 실시예 2보다는 저하되었으나, 기재를 천을 사용하기 때문에 플라스틱 수지를 기재로 사용하지 못하는 제품에 다양하게 적용하여 발광시킬 수 있는 장점이 있다.In Example 1 according to the present invention, since the uneven part of the coating surface disappears, contamination does not occur even if used for a long time, and it is understood that luminance is excellent after elapse of time, and Example 2 performs afterglow luminance over time. Although lower than Example 2, since the substrate is used as a substrate, there is an advantage that can be applied to a variety of products that do not use a plastic resin as a substrate to emit light.

이상에서는, 본 발명을 특정의 바람직한 실시예에 대해서 도시하고 설명하였다. 그러나, 본 발명은 상술한 실시예에만 한정되는 것은 아니며 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자라면 이하의 특허청구범위에 기재된 본 발명의 기술적 사상의 요지를 벗어남이 없이 얼마든지 다양하게 변경실시 할 수 있을 것이다.In the above, the present invention has been illustrated and described with respect to certain preferred embodiments. However, the present invention is not limited only to the above-described embodiments, and those skilled in the art to which the present invention pertains can vary as many without departing from the spirit of the technical idea of the present invention described in the claims below. Modifications may be made.

이상에서 설명한 바와 같이, 본 발명에 의한 축광성 발광시트는 축광성 발광체를 바인더에 분산 혼합하여 기재층의 상면에 1회 이상 도포하고, 그 상면에 투명의 바인더로 코팅함으로써 태양광이나 인위적인 조명의 빛을 조사 받아 흡수하여축적하였다가 빛이 제거된 상황에서 발광하는 것으로, 본 발명에 의한 축광성 발광체의 입자가 도포면에서 밀도가 극히 작고, 또한 코팅면내에서 서로의 난반사(難反射)로 인하여 잔광휘도가 뛰어날 뿐 아니라 잔광시간이 오래가는 효과가 있다.As described above, the photoluminescent light emitting sheet according to the present invention is dispersed and mixed with the photoluminescent emitter in a binder and applied to the upper surface of the substrate layer one or more times, and coated with a transparent binder on the upper surface of the solar light or artificial lighting. It emits light when it is irradiated, absorbed and accumulated, and emits light when the light is removed. The particles of the photoluminescent emitter according to the present invention have extremely low density at the coating surface, and afterglow due to diffuse reflection of each other in the coating surface. Not only is it excellent in brightness, it is also effective for long afterglow time.

이와 같이 본 발명에 의한 축과성 발광시트는 옥외에서 사용할 수 있으며, 방사선 물질을 함유하지 않는 무독성이고, 안전성이 보장되어 산업안전시설에 효과적으로 사용하여 안전사고를 예방할 수 있고, 문구 및 팬시, 각종 인테리어와 선박 및 도로의 안전표식 등에 걸쳐 광범위하게 적용할 수 있는 유용한 발명인 것이다.As described above, the condensed light emitting sheet according to the present invention can be used outdoors, and it is non-toxic and does not contain any radioactive material, and its safety is ensured, so that it can be effectively used in industrial safety facilities to prevent safety accidents, stationery, fancy, various It is a useful invention that can be applied to a wide range of interior and safety signs of ships and roads.
