Problems solved by technology

[0004] Second, the strength of the soft fluorescent film is not enough, and the smoothness and damage resistance are not enough;
[0005] Third, use a single-layer fluorescent film. In order to ensure the flatness of the top surface, the top of the fluorescent film will be ground during the subsequent grinding process, which will affect the optical properties of the fluorescent film, and then affect the consistency of light output.

Embodiment Construction

[0041] The present invention will be described below in conjunction with the accompanying drawings and specific embodiments.

[0042] Such as figure 2 As shown, a composite fluorescent film 11 includes a soft glue film and a hard glue film 1 fixed on the top of the soft glue film. The suction part where the adhesive film is removed from the blue film 3 as a whole.

[0043] The soft adhesive film is a fluorescent film 4, and the side of the fluorescent film 4 protrudes to the outside of the hard adhesive film 1 to form an extending end 5, which is used to reduce the overall deformation of the composite fluorescent film 11 in the subsequent packaging process. The fluorescent film 4 is in the shape of a trapezoid, and the hard rubber film 1 is also in the shape of a trapezoid. The bottom surface of the hard rubber film 1 with a larger area is attached to the top surface of the fluorescent film 4 with a smaller area, and the composite fluorescent film 11 is in the shape of a tra...

Abstract

The invention provides a composite fluorescent film, comprising a soft glue film and a hard glue film fixed on the top of the soft glue film, the hard glue film is formed to be sucked by a suction cup so that the hard glue film and the soft glue film The suction part where the adhesive film is completely removed from the blue film. The composite fluorescent film has the advantages of high strength, easy absorption and easy processing. In addition, the invention also provides a production process of the composite fluorescent film and an LED packaging process using the composite fluorescent film.

Description

technical field [0001] The invention relates to the technical field of LED encapsulation, in particular to a composite fluorescent film and an LED encapsulation process. Background technique [0002] In the prior art, when pasting the fluorescent film, a single-layer fluorescent film is used, but there are the following problems: [0003] First, in the step of absorbing the fluorescent film from the blue film, the middle position of the fluorescent film is first pushed up from the bottom of the blue film by the push rod, and then sucked by the suction cup, such as Figure 6 As shown, because the fluorescent film is soft, the side part of the fluorescent film is easy to stick to the blue film, resulting in less active area of ​​the suction cup, and the suction cup is not easy to absorb; [0004] Second, the strength of the soft fluorescent film is not enough, and the smoothness and damage resistance are not enough; [0005] Third, use a single-layer fluorescent film. In orde...
