Abstract
A broadband, omnidirectional, multi-layer, dielectric reflector for an LED in a white light emitting device provides both near 100% reflectivity across the visible spectrum of light, and electrical insulation between the substrate and the electrical circuitry used to power and control the LED. When a sealant material, having a higher index of refraction than air, is used to protect the LED and the accompanying electrical circuitry, an aluminum reflector layer or substrate is provided to make up for the loss of reflectivity at certain angles of incidence. The dielectric reflector includes two separate sections with two different thicknesses, a thinner section below the LED providing better heat conductivity, and a thicker section surrounding the LED providing better reflectivity.
