Abstract

A light emitting diode (LED) module that is configured to emit white light is provided. The LED module includes: a blue light emitting diode configured to emit blue light having a first peak wavelength of 420 nm to 465 nm; at least one wavelength conversion material that is configured to convert a portion of the blue light into converted light of a different wavelength; and a near-infrared light source configured to emit additional light having a second peak wavelength in a range of 740 nm to 900 nm and a full width at half maximum (FWHM) of 120 nm or less. The converted light, another portion of the blue light, and the additional light combine to form the white light.
