Abstract

The invention discloses an integrated conical COB packaged LED light source, comprising a package substrate, an LED light source, a package glue and a rubber ring, the package substrate is integrally formed in a conical shape, and the LED light sources are arranged in an array On the substrate, the encapsulation glue covers the LED light source in a mesh shape, and the rubber rings are arranged at the upper end and the lower end of the encapsulation glue. The integrated conical COB packaged LED light source provided by the present invention and its preparation method design the packaging substrate into an integrally formed conical shape, and the light-emitting surface is arranged on the side of the cone to emit light obliquely, so the light-emitting surface on the side is formed as a The complete curved surface can realize omnidirectional and large-angle light output from the side; and, since the LED light sources on the packaging substrate are connected by gold wires printed on the packaging substrate and fixed by packaging glue, the processing is simple and the consumables are less , high reliability.

Description

technical field [0001] The invention relates to an integrated conical COB packaged LED light source and a preparation method thereof. Background technique [0002] At present, LED light sources are gradually developing into COB packaging, which can reduce costs and improve reliability. In the prior art, all COB packages use a planar package. If you want to achieve omnidirectional light output from the side, you must use a splicing scheme of multiple planar packages. However, the multi-block splicing solution is not only costly, but also poor in reliability and light output. [0003] Therefore, it is necessary to design a new COB packaging solution to package the LED light source to solve the problems existing in the prior art. Contents of the invention [0004] In order to overcome the defects in the prior art, the technical problem to be solved by the present invention is to provide a COB packaged LED light source capable of realizing omnidirectional light emission from...
