US Patent 11424393 Light-emitting diode and light-emitting module

A light-emitting module and a light-emitting diode are provided. The light-emitting diode includes an epitaxial light-emitting structure to generate a light beam with a broadband blue spectrum. A spectrum waveform of the broadband blue spectrum has a full width at half maximum (FWHM) larger than or equal to 30 nm. The spectrum waveform has a plurality of peak inflection points, and a difference between two wavelength values to which any two adjacent ones of the peak inflection points respectively correspond is less than or equal to 18 nm.
