Sony patents light fixture that mixes colors using a hollow tube
Sony describes a light source device that splits a single beam of excitation light into multiple smaller beams. These beams are directed into a hollow tube where they hit specific spots called wavelength converters, which change the light into different colors or bands.
In the filing’s own words
A light source apparatus according to one embodiment of the present disclosure includes: a light source unit that divides excitation light into a plurality of light beams and outputs the plurality of light beams; a light guide member including, on an inner side thereof, a hollow light guide path having a first opening and a second opening on a side opposite to the first opening, the light guide member having a plurality of wavelength converters provided on at least a portion of a side surface of the light guide path, the plurality of wavelength converters being configured to emit light beams having wavelength bands different from each other; and a light condenser device that guides each of the plurality of light beams output from the light source unit to a corresponding one of the plurality of wavelength converters.
What exactly they claim (claim 1)
1. A light source apparatus, comprising: a light source unit that divides excitation light into a plurality of light beams and outputs the plurality of light beams; a light guide member including, on an inner side thereof, a hollow light guide path having a first opening and a second opening on a side opposite to the first opening, the light guide member having a plurality of wavelength converters provided on at least a portion of a side surface of the light guide path, the plurality of wavelength converters being configured to emit light beams having wavelength bands different from each other; and a light condenser device that guides each of the plurality of light beams output from the light source unit to a corresponding one of the plurality of wavelength converters.
