Problems solved by technology

[0004] The above-mentioned traditional way of manufacturing light-emitting diodes by dispensing is because the chip of the light-emitting diode is completely packaged and filled. function, and the heat dissipation is not easy, so the packaging silicone can not withstand high temperature, and it is easy to deteriorate and become brittle.
For this reason, generally known LED light-emitting diodes are only suitable for low-power use, their brightness is very limited, and their service life is not long, so they cannot break through to the ideal state of high-power, and it is difficult to devel

Abstract

The invention relates to a light emitting diode lamp shade which can be in injection or extrusion molding by utilizing intramode transfer printing film; the lamp shade is characterized in that: the intramode transfer printing film can be combined and molded at the light emitting diode in the method of continuous plastic injection or extrusion molding; the intramode transfer printing is that an intramode transfer printing film can be printed and completed rapidly through a printing machine or a printer or other output equipment; a parting layer, a printing layer with selective phosphor material and an adhesion layer is formed at a substrate underlayer of the intramode transfer printing film by using a printing contraposition method in sequence; thereby the light emitting diode which is composed of the lamp shade and a blue light diode chip can generate white light, or which also can be used in re-imprinting various appointed pigment ink layers on the printing layer, so that various color lights can be generated. The light emitting diode lamp shade has the advantages of lowering cost in mass production, long service life and good heat dissipation effect.

Description

technical field [0001] The invention relates to a light-emitting diode (LED element) lampshade design for injection / extrusion molding by using an in-mold transfer film. Background technique [0002] The known in-mold transfer film refers to placing the printed film in the mold cavity, and then injecting the rubber to complete the injection / extrusion molding. In-mold transfer printing is usually used in the production of key elements that require extremely high quality performance and decoration. Sexual components, such as the production of mobile phone casings, cosmetic packaging containers, buttons, auto parts or information and electrical components. [0003] Furthermore, in the known manufacturing process of light-emitting diodes (LEDs) with various colors, it is necessary to use glue dispensing to pre-package and fill the chip of the light-emitting diode with silica gel containing an appropriate amount of fluorescent powder. Set up a general encapsulation colloid, which...
