METHODS OF TUNING LIGHT EMITTING DEVICES AND TUNED LIGHT EMITTING DEVICES

摘要

Methods of treating an emission spectrum of visible light emitted from a light emitting source, and resulting apparatus, are disclosed. The methods include obtaining the visible light emission spectrum emitted from the light emitting source and a desired visible light emission spectrum. The methods may also include determining at least one wavelength of the emission spectrum of the source with an irradiance or intensity that is less than that of the desired emission spectrum. The methods may include selecting at least one pigment that is effective in tuning the emission spectrum of the source by increasing the intensity or irradiance of the at least one wavelength. The methods may include applying the at least one pigment to the light emitting source to treat the emission spectrum emitted therefrom.

1. A method of tuning a first emission spectrum of visible light emitted from a light emitting source with a first luminosity, when energized, comprising:
obtaining a first visible light emission spectrum emitted from a light emitting source including the intensity of wavelengths within the visible spectrum; obtaining a desired second visible light emission spectrum including the intensity of wavelengths within the visible spectrum; determining at least one first wavelength of the first visible light emission spectrum with an intensity less than the at least one wavelength in the second visible light emission spectrum; selecting at least one pigment that substantially absorbs wavelengths within the visual spectrum and is effective in increasing the intensity of the at least one first wavelength; and applying the at least one pigment to the light emitting source in a first density that tunes the first emission spectrum of the light emitting source by increasing the intensity of the at least one first wavelength and decreasing the first luminosity by less than about 25%.
