This invention provides a light-transmitting and water-blocking packaging film, comprising a packaging label layer, a front protective film, a back protective film, reinforcing sheets, carbon black areas, and a sealing frame. The packaging label layer, the front protective film, and the back protective film are composited to form a sandwich structure, with several reinforcing sheets disposed between them. Corresponding carbon black areas are provided on the packaging label layer, the front protective film, and the back protective film. The sealing frame is integrally formed on the surface of the back protective film. This invention uses a sandwich structure composite packaging label layer, etc., with circular glass fiber reinforcing sheets in between to improve tensile strength. The gradient carbon black areas at the edges of the three films absorb ultraviolet rays and resist aging. The inner adhesive area of ​​the arc-shaped sealing frame at the edge of the back protective film is sealed and water-blocking, protecting the items.

The invention discloses an LED packaging colloid presenting a non-luminous color and a preparation method thereof, and belongs to the technical field of semiconductor device packaging. The packaging colloid is composed of a colloid base material and inorganic color paste uniformly dispersed in the colloid base material. The specific preparation method comprises the steps of material preparation, premixing, vacuum stirring and defoaming, dispensing, curing and the like, and inorganic color paste is uniformly mixed and cured in colloid. According to the LED device applying the colloid, the packaging colloid can present a stable preset color when the colloid is not powered on, light emitted after the colloid is powered on penetrates through the colloid, and the light emitting color is in visual coordination with the natural color of the colloid. According to the invention, the integration of the coloring effect and the packaging body is realized, the problems that the external coloring is easy to fall off and discolor and the lighting effect is influenced are solved, and the advantages of firm coloring, strong weather resistance, good process compatibility, environmental protection, reliability and the like are realized.
