Abstract: An optical member that is shaped to collect light from a source, such as an LED, and refract the light to form a desired beam pattern is made of an optically transmissive or transparent polymeric material in which is dispersed an energy converting phosphor that absorbs blue light and emits visible light at a wavelength that is longer than the absorbed blue light.

Abstract: A lens member for projecting light from an LED in a square pattern includes a body formed of a light transmissive material. The body includes a base portion and a bulbous-shaped, light-directing lens portion extending upwardly from the base portion. A recess extending upwardly from a lower surface of the base portion and into the bulbous-shaped, light-directing lens portion continuously tapers from the base to a flat, circular surface below a top surface of the bulbous-shaped, light-directing lens portion. The lens portion has a horizontal cross-sectional shape that is substantially square at elevations between the base and the top surface of the lens portion.

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.
