Abstract
An illuminating optical lens article of manufacture for use with a light emitting diode (LED) mounted on a circuit board has (a) a base portion defining a rim on a plane having a bottom surface around a longitudinal axis for mounting over the LED; (b) an integral refractive outer surface of the lens extending towards the longitudinal axis from the base; (c) an integral refractive inner surface of the lens extending from the base forming a cavity shaped and sized to receive an LED; and optionally (d) a plurality of grooved sections for receiving an adhesive formed on the bottom surface of the base portion. The base is adapted to be mounted on the circuit board onto which the LED is mounted. The integral refractive outer and inner surfaces each define a predetermined geometry adapted to direct and focus light emitting from the LED to a predetermined path.
