Inorganic encapsulation direct-plug type violet LED and manufacturing method thereof

Abstract

The invention discloses an inorganic encapsulation direct-plug type violet LED and a manufacturing method thereof. The inorganic encapsulation direct-plug type violet LED comprises a metal ceramic base, a metal component serves as an upper component of the metal ceramic base, a ceramic component serves as a lower component of the metal ceramic base, a groove concaved inwards is formed in the center of the upper surface of the metal component, a layer of die bond glue is arranged at the inner bottom of the groove, a violet chip is fixed to the die bond glue, and a glass metal cap is buckled to the metal ceramic base and further comprises a metal tube and a glass cover, wherein the two through openings are formed in the two ends of the metal tube, and the glass cover is embedded in the upper end opening of the metal tube. According to the inorganic encapsulation direct-plug type violet LED, glass, metal, ceramic and other inorganic materials replace epoxy resin, silicon gel and other organic materials to serve as the encapsulation materials of the violet LED, the sealing protection on a violet LED chip is greatly improved, the application range of the violet LED in special environments is effectively widened, the heat dissipating performance of the violet LED is also improved, and the anti-aging capability of the violet LED is improved.

Description

technical field [0001] The invention relates to the technical field of LED production, in particular to an inorganic packaging in-line violet LED and a manufacturing method thereof. Background technique [0002] In the prior art, organic materials such as epoxy resin and silica gel are often used to seal and protect the chips in the packaging of in-line purple LEDs. These inorganic materials have excellent transparency, convenient packaging, and can improve light extraction efficiency. They are widely used in many fields. application. [0003] However, in the case of harsh environments, such as high temperature, chemical volatilization and corrosion, optical communication, dust protection, and easy wear and tear, violet LEDs packaged with organic materials cannot meet the requirements, and are prone to failure, or even dead lights. Contents of the invention [0004] The purpose of the present invention is to overcome the above defects of the prior art, provide an inorgani...
