Abstract:
In one embodiment of this invention, a light filtering directional control element provides increased spatial color or luminance uniformity and desired angular color uniformity and customizable light re-direction properties. In one embodiment of this invention, a light filtering directional control element directs light off-axis and focuses light in the far field. In a further embodiment of this invention a light fixture comprising the light filtering collimation element has a spatial luminance uniformity greater than 80%, a color uniformity Δu′v′ of less than 0.04 and a short mixing distance. In a further embodiment, the light fixture incorporating the element has electronically or manually configurable light output profile.
