LED module, LED lamp, and illuminating apparatus
To constrain reductions in luminous efficacy while enhancing the color rendition index, the LED module includes a blue LED, at least one variety of phosphor particles excited by the outgoing light from the blue LED, and neodymium glass particles that include neodymium ions absorbing the outgoing light from the phosphor particles in a predetermined wavelength band.
