Abstract:
A light emitting diode (LED) component comprises an LED having a dominant wavelength in a range of from about 425 nm to about 475 nm, and a first phosphor and a second phosphor are in optical communication with the LED. The first phosphor has a peak emission wavelength in the range of from about 600 nm to about 700 nm, and the second phosphor has a peak emission wavelength in the range of from about 500 nm to about 600 nm. An excitation spectrum of the first phosphor includes, at excitation wavelengths longer than 530 nm, no intensities greater than about 60% of a maximum intensity of the excitation spectrum.
