Abstract
Light fixtures achieve improved efficiency by utilizing a reflective holographic optical element to direct light from a light source to a task area. The light fixture can employ any conventional source of artificial incoherent light positioned relative to the reflective holographic optical element such that the reflected light is collimated to provide efficient illumination of the task area.
