Optical manifold for light-emitting diodes

摘要: An optical manifold for efficiently combining a plurality of LED outputs into single, substantially homogeneous output, in small, cost-effective package. The manifolds can be used to combine multiple LEDs the same color and provide high intensity output aperture with very uniformity sharp borders, or they generate multiwavelength such as red, green, due that are combined white light. Embodiments also disclosed use single remote phosphor an intermediate wavelength-selective filter arranged so backscattered photoluminescence is recycled boost luminance flux aperture. designed alleviate substantial inhomogeneities inherent LEDs. utilizes principles non-imaging optics transform light directed, uniform sources.
