Abstract
A variable angle beam control device is capable of maintaining the same color temperature of the light source regardless of the changes in the angle of the beam. The controllable light beam device has a light source with primary optics producing a low divergence light beam having an inverted angular distribution of the correlated color temperature (CCT), and a liquid crystal device with an electrically variable refractive index distribution arranged to receive said light beam and to provide a variable angle beam.
