A kind of preparation technology of green fluorescent film

Abstract

that The present invention relate to the field of lighting technology, in particular to a preparation process of a green fluorescent film, comprising the following steps of: mixing and stirring 3 to 10 parts by weight of green fluorescent powder, 88 to 98 parts by weight of UV glue, 1 to 5 parts by weight of diffusion powder and 0.1 to 1.2 parts by weight of dispersion solvent to form a mixture; 2, coat that mixture to a base film by a coating machine to form a green fluorescent film; 3, excite that green fluorescent film by adopting a purple-red lamp, and synthesize the purple-red light of the purple-red lamp and the green light of the green fluorescent film to obtain the required white light. The green fluorescent film prepared by the method, The brightness of the green fluorescent filmis higher than that of the quantum film, and the color gamut of the green fluorescent film is about 100. In addition, the production cost of the green fluorescent film is lower than that of the quantum film, and the production cost of the green fluorescent film is more than half of that of the quantum film.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a preparation process of a green fluorescent film. Background technique [0002] LED is a solid-state semiconductor device that can directly convert electrical energy into light energy. It has the advantages of high luminous efficiency, low power consumption, fast response, small size, long life, shock resistance and suitable for mass production. With the development and progress of science and technology, LED technology is more and more widely used in people's daily life, such as various LED lamps and LED display screens. [0003] At present, the luminescent material used in white LED fluorescent film is mainly yellow phosphor, the main component of which is rare earth elements, which is a non-renewable resource, and the price is relatively high, which makes the production cost of LED relatively high. With the development of the times, the use of quantum dots to make quantum d...
