Patent ID: 8573815

Claim:
An illuminating optical lens article of manufacture for use with a light emitting diode (LED) mounted on a circuit board which comprises: (a) a lens having a base portion defining a rim on a plane having a bottom surface around a longitudinal axis (A-A) for mounting over the LED; (b) an integral refractive outer surface of the lens extending around and angled towards the longitudinal axis (A-A) 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 (d) a plurality of grooved sections for receiving an adhesive formed on the bottom surface of the base portion, each of the plurality of grooved sections having a plurality of grooves that extend radially of the longitudinal axis; wherein the base is adapted to be mounted on the circuit board onto which the LED is mounted; wherein 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; and wherein the lens is fabricated with a tolerance range of the inner surface within 0.15 mm of the LED.
