Definitions
- the invention belongs to the field of LED display and illumination technology.
- the invention relates to a strippable fluorescent material light-converting luminescent film, which can convert blue light emitted by an LED into white light, and specifically relates to a layered film product made of a luminescent material, a luminescent coating and a resin film. It also relates to a peelable light-converting luminescent film for a light-emitting device including an LED backlight, a digital display, and illumination. Background technique
- the current LED backlights, digital display and illumination devices are usually obtained by encapsulating fluorescent materials.
- the white light emitting device prepared by the method is difficult to ensure the consistency of brightness, color coordinates, color temperature and color rendering, and since the phosphor is close to the chip, it is easily affected by heat and the life is lowered.
- WO2007049187 describes a sealing film agent for silicone-doped phosphor, which is mounted on a blue LED to achieve the purpose of converting blue light into white light, but the material itself is a film-like structure, which needs to be used according to the use. Laminated party Secondary molding, complex process.
- U.S. Patent No. 6,600,175 B1 mentions the use of organic fluorescent and phosphorescent materials in a white LED package for packaging instead of LED phosphors. The composite emits white light, which is only a single device coating, and can only be realized simply by using an electric light source. Certain difficulty.
- Patent CN1 01 533882A introduces a phosphor pre-formed film for white LED and a preparation method thereof, which is prepared by screen printing method, and the continuous and large-area film production cannot be realized in the process.
- Patent CN1 01443192A discloses a photoluminescent plate.
- the photoluminescent plate In order to protect the matrix resin layer and improve heat resistance and moisture resistance, the photoluminescent plate preferably uses a PET polyester film as a protective film, although after removing the protective film, The photoluminescent plate is used, but it is generally preferred to maintain a protective film for adhesion for protection.
- the photoluminescence plate is prepared by screen printing, slit coating or roll coating, etc., by printing a mixture of a phosphor or the like and adjusting the viscosity of the silicone resin mixture onto the protective film.
- the board usually has a thin luminescent coating and is difficult to produce a thicker luminescent coating.
- An object of the present invention is to provide a peelable type light-converting film which is used as a substrate and a protective film by a fluorine-based polyester film which can be easily peeled off when used in a light-converting film.
- the prepared peelable light conversion film has high uniformity, good homogenization, anti-glare, high light conversion efficiency, low cost, excellent aging performance, and simple production process.
- the peelable type light-converting luminescent film according to the present invention is composed of a substrate and a photo-conversion coating layer thereon, and the photo-transformation coating layer is composed of a fluorescent material, a two-component silicone resin, a diluent, and an auxiliary agent.
- the substrate described above is a fluorocarbon polyester film which is used as a substrate when preparing a light-converting luminescent film to function as a protective film; it can be easily peeled off from the photo-converting coating layer during use. Since the fluorine polyester film is used as the substrate, when the light conversion luminescent film is prepared, it can function as a coating production substrate and a protective film. In addition, due to the use of the light conversion coating layer, the main resin is silicone.
- the resin itself is soft and elastic, and is easily deformed when the protective film is peeled off, resulting in uneven thickness of the light conversion film, thereby affecting the luminescent property. Therefore, the present invention uses a fluorocarbon polyester film as a substrate and a protective film. When used, the light conversion coating layer can be easily peeled off from the fluorine polyester film, thereby avoiding deformation due to stretching, and ensuring that the products of the light conversion film are hooked and stable.
- the fluoropolyester film is a polyester film coated with a fluorine release agent.

目前的 LED 背光源、 数码显示及照明装置通常是采用封装 荧光材料的方式得到的， 此类专利也已经有很多如中国专利 CN1941431 〈白色发光元件及其制造方法>， CN151 0766 〈表面安 装型白色发光二极管〉， CN1 01 186818 〈蓝紫光或蓝光激发的荧 光体及制造方法与封装的白光二极管 >， 均为荧光材料混合在树 脂中涂覆在 LED 芯片上制成白色发光器件。 该方法制备出的白 光发光器件很难保证亮度、 色坐标、 色温和显色性的一致性， 并且由于荧光粉贴近芯片， 受到热量的影响很容易引起老化， 寿命降低。 国际专利 WO20071 05853介绍了一种光致发光膜的制 备方法， 所釆用的发光材料为无机发光材料， 该专利采用涂膜 方式在基材膜上进行制备， 并未对具体工艺进行介绍， 并且制 备出的光致发光膜与基材结合为一体， 在使用中由于基材物质 折射率与光致发光层并不一致， 会损失部分光效。 国际专利
WO2007049187 介绍了一种釆用硅酮掺杂磷光体的密封膜剂， 将 这种膜材料安装在蓝光 LED 上， 达到蓝光转换为白光的目的， 但是这种材料本身为膜状结构， 需根据使用情况采用层压的方
式二次成型， 工艺复杂。 美国专利 US 6600175B1提及在白光 LED 封装中采用有机荧光、 磷光材料， 替代 LED 荧光粉进行封装， 复合发出白光， 只是单个器件的涂装， 只能简单实现电光源， 在面光源的应用上有一定难度。 中国专利 CN1 01 533882A介绍了 一种白光 LED 用荧光粉预制薄膜及其制备方法， 采用的是丝网 印刷的方法进行制备， 工艺上无法实现连续、 大面积膜的生产。 专利 CN1 01443192A公开了一种光致发光板， 为了保护基质树脂 层， 提高耐热性和耐湿性， 该光致发光板优选采用 PET 聚酯膜 为保护膜， 虽然在移除保护膜之后也可以使用该光致发光板， 但通常是优选保持粘附的保护膜， 用于保护作用。 另外该光致 发光板采用丝网印刷、 狭缝涂覆或辊涂等将加入荧光体等并调 节好粘度的有机硅树脂混合液印刷到保护膜上的方法制备， 这 样制得的光致发光板通常发光涂层较薄， 如果需生产较厚发光 涂层时有难度。

1. 由于可剥离型光转换膜中的氟素聚酯膜在制备时作为 基材使用， 可以起到保护膜作用； 在使用时可以很容易剥离， 避免引起光转换涂料层的变形， 剥离后减少了光的折射， 提高 了发光效率。
2. 由于用来制备可剥离型光转换膜的荧光材料预先经过 乙醇-烷氧基低聚硅氧烷混合液， 因而提高了其与有机硅树脂的 相容性， 改善涂膜表面状态， 提高膜的均匀度。
3. 采用涂布法制备可剥离型光转换膜可以实现不同厚度 的涂布要求， 制备出各种厚度的光转换膜， 并且可以实现连续 生产， 生产效率高。 另外由于采用涂布方式对光转换涂料的粘 度和荧光材料的粒径要求比较宽， 更易于进行生产。
