摘要： Shades and/or reflectors for luminaires. The luminaires may be retrofitted with the shades and/or reflectors to selectively control the direction and/or spectrum of light emitted by the luminaires. In particular, the efficiency and/or color contrast of a luminaire may be improved by using wavelength shifting material, such as a phosphor, to absorb less desired wavelengths and transmit more desired wavelengths. The shade may provide a transmissive filter which reflects desired wavelengths such as red and green, while passing less desired wavelengths (e.g., blue) toward the wavelength shifting material which emits such as light of more desirable wavelengths.
