Abstract
A method of manufacturing a light source includes providing a substrate with electronic circuitry to drive light emitting diodes (LEDs); coupling a plurality of LEDs to the electronic circuitry on the substrate, the LEDs with more than one color types; and attaching a mixing barrel around the plurality of LEDs over the substrate, the mixing barrel with a reflective internal wall.

A point light source comprising:
- a substrate with electronic circuitry to color tune light emitting diodes (LEDs);
- a plurality of LEDs on the substrate coupled to the electronic circuitry, the LEDs with more than one color types;
- and
- a mixing barrel around the plurality of LEDs, the mixing barrel with a reflective internal wall.

A point light source comprising:
- an electronic circuitry to drive light emitting diodes (LEDs);
- a plurality of LEDs coupled to the electronic circuitry, the LEDs with more than one color types;
- a light pipe over the plurality of LEDs to provide total internal reflection of light rays from the plurality of LEDs for light ray angles larger than a critical angle with respect to a normal vector of a surface of the light pipe;
- and
- a reflective wall around the plurality of LEDs and around at least part of the light pipe.
