Patent attributes
A lighting system include a point light source, a tubular color adjustment means, and a light-collecting and mixing element. The color adjustment means has a color-converting tubular structure and an adjusting rod. The tubular structure is made of a light-transmitting medium doped with a wavelength-converting material. The adjusting rod is operably connected to and for adjusting the tubular structure. In operation, the point light source emits light of a first wavelength or hue. The color adjustment means adjustably intersects, through the use of the adjusting rod, the light of the first hue and converts at least a portion of the light of a first hue into a light of another hue. The light-collecting and mixing element collects and mixes the light of a first hue and the light of another hue, and directs the mixed light out the open end.
