Problems solved by technology

Therefore, the shortcomings of the point light source failures that are prone to occur in the existing conventional lighting modules cannot be improved through the above-mentioned improvements.
In addition, since the packaging material often needs to have a light mixing effect, the output light source can output the light source of the required color after passing through the fluorescent material in the packaging material. The degree is different, resulting in poor visual effect

preparation example 1 to 6

[0070] The light-color conversion layer compositions of Examples 1 to 6 were prepared according to the methods described below, and their compositions are listed in Table 1.

[0071] Firstly, each component was mixed with the weight (grams) listed in Table 1, and stirred at room temperature and in a dark room until completely mixed uniformly to form a photochromic conversion layer composition. Then, at a curing energy of 1500 millijoules / square centimeter (mJ / cm 2 ) conditions, a 100-micron thick photochromic conversion layer was formed on a 500-micron glass substrate (91.4% transmittance).

Embodiment 1 to 6 and comparative example 1 and 2

[0089] In the same manner as in Preparation Examples 1 to 6 and as described below, each component was mixed with the weight (grams) listed in Table 3, wherein component (e) was further added to form a glue solution of the light-color conversion layer composition. Then, at a curing energy of 1500 millijoules / square centimeter (mJ / cm 2 ) conditions, a 100-micron thick photochromic conversion layer was formed on a 500-micron glass substrate (91.4% transmittance).

Abstract

The invention relates to a photochromic switching film comprising a substrate and a photochromic switching layer on the substrate, wherein the photochromic switching layer is produced by a composition including fluorescent powder, acrylate functional group oligomer, acrylate functional monomer, and optical initiator. The fluorescent powder is the sole powder in the composition. The thickness of the photochromic switching layer is from 100 to 300 micrometer. The invention also relates to a method for producing the photochromic switching film. The method comprises applying the composition including the photochromic switching film to the substrate and solidifying the composition in order to form the photochromic switching film. The photochromic switching film in the invention has excellent light dividing performance and a long service life without the use of photodiffusion particles and is not required to subjected to a solvent production process. The photochromic switching film is used in cooperation with a lighting device such as a light emitting diode and has environmental-friendly and energy-saving characteristics.

Description

technical field [0001] The invention relates to a light-color conversion film and a manufacturing method thereof, and in particular to a light-color conversion film suitable for light-emitting diodes (LEDs) or organic light-emitting diodes (OLEDs) and providing excellent light uniformity. Background technique [0002] With the prosperity and rapid development of the green energy industry, such as renewable energy such as solar wind power generation and the LED / OLED lighting industry, various energy-saving lighting products have become increasingly popular in daily life. Among these lighting products, LED / OLED illuminators have attracted the most attention. How to provide products that are brighter, more power-efficient and have better visual effects has always been one of the main research and development goals of the industry. In recent years, the industry has been more committed to improving the packaging materials of LED / OLED and the integration of LED / OLED modules, and ...
