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; and a near-infrared wavelength conversion material that is configured to be excited by the blue light to emit additional light having a peak wavelength in a range of 740 nm to 900 nm, and further having a full width at half maximum (FWHM) of 120 nm or less. The near-infrared wavelength conversion material includes Ca(Al,Ga)O:xCr(0≤x≤1, 0≤y≤6).
