Abstract

An LED assembly includes a substrate, an LED module mounted on the substrate, and a lens plate disposed on the substrate. The lens plate has a lens portion disposed atop the LED module and defining a space between an inner surface of the lens portion and the LED module. A filler material having a refractive index greater than air fills the space between the LED module and the inner surface of the lens portion. The LED module includes a chip holder mounted on the substrate, a red LED chip mounted on the chip holder, and an optical encapsulant covering the top surface of the LED chip. The LED module is a plastic leaded chip carrier package. The refractive index of the filler material preferably differs from the refractive index of the optical encapsulant by at most ±0.3.
