Problems solved by technology
[0002] LED devices for lighting have been available for more than ten years, and high-power LED lighting devices have also been researched and used for several years. Light-emitting devices as carriers of communication information have become a hot research topic in the past two years, but the promotion and application of this technology have been restricted by ordinary people. The corresponding frequency of LED devices is restricted. If micron-level LED devices are used, although the corresponding frequency is increased, there is a problem of poor lighting effect. That is to say, the current light-emitting devices for communication are still in the initial stage of application. Is limited

Description
technical field [0001] The invention relates to the field of visible light communication, in particular to an embedded lighting communication dual-function LED device and a manufacturing method thereof. Background technique [0002] LED devices for lighting have been available for more than ten years, and high-power LED lighting devices have also been researched and used for several years. Light-emitting devices as carriers of communication information have become a hot research topic in the past two years, but the promotion and application of this technology have been restricted by ordinary people. The corresponding frequency of LED devices is restricted. If micron-level LED devices are used, although the corresponding frequency is increased, there is a problem of poor lighting effect. That is to say, the current light-emitting devices for communication are still in the initial stage of application. Is limited. Contents of the invention [0003] The purpose of the presen...
