Full Spectrum White Light Emitting Devices |
| abstract |
A full spectrum white light emitting device includes photoluminescence materials which generate light with a peak emission wavelength in a range from about 490 nm to about 680 nm; and a broadband solid-state excitation source operable to generate broadband excitation light with a dominant wavelength in a range from about 420 nm to about 480 nm. The device is operable to generate white light with a Correlated Color Temperature in a range from about 1800K to about 6800K, a CRI R9 less than 90, a spectrum whose intensity decreases from its maximum value in the orange to red region of the spectrum to about 50% of the maximum value at a wavelength in a range from about 645 nm to about 695 nm, and over a wavelength range from about 430 nm to about 520 nm, a maximum percentage intensity deviation of light emitted by the device is less than 60% from the intensity of light of at least one of a black-body curve and CIE Standard Illuminant D of the same Correlated Color Temperature. |
