1. A visible light communication emission device with improved response frequency, comprising a substrate, wherein an inductance coil module is provided on the substrate, a LED chip matrix formed by series connection of a plurality of LED chips is provided on the inductance coil module, and the inductance coil module and the LED chip matrix are connected in series, wherein inductance value L of the inductance coil module is configured to be:

  • L=1/(ω

    2C), with C representing capacity in the device provided by LED chips and ω

    representing frequency, wherein the inductance coil module comprises more than one inductance coil whose composition materials from inside to outside are successively Cr, Al, Cr, Ti, and Ag.
