Abstract: A mounting surface for mounting a plurality of LEDs has a plurality of orientable lenses each individually affixed about a single LED. Each orientable lens has a primary reflector and a refracting lens that direct light emitted from a single LED to a reflective surface of the orientable lens that reflects the light off a primary LED light output axis.

Abstract: An illumination system for illuminating a surface includes an optical source for generating light. An asymmetric optic device generates output light by total internal reflection (TIR) of the light from the optical source, intensity of the output light being asymmetric with respect to an axis of the asymmetric optic device. A diffuser receives and diffuses the output light from the asymmetric optic device to generate diffused light. A cover lens receives the diffused light from the diffuser. The cover lens has an etched portion for scattering a portion of the diffused light to generate an output light pattern, the output light pattern having an intensity profile that is asymmetric with respect to the axis of the asymmetric optic device.

Abstract: An LED assembly that includes optics and optical arrangements for light emitting diodes (LEDs). In some embodiments, a reflector is provided within a void between the lens and the LED. This reflector can reflect light emitted by the LED in a non-preferred direction back toward the preferred direction. In other embodiments, an optical element is formed or otherwise provided in the lens cavity and shaped so that, when the lens is positioned above the LED, the refractor bends the emitted light in a preferred direction. In some embodiments, both a reflector and optical element are provided in the LED assembly to control the directionality of the emitted light. Such embodiments of the invention can be used to increase the efficiency of an LED by ensuring that generated light is being directed to the target area of choice.

Abstract: The invention relates to a light distribution method for a COB module LED street lamp lens capable of illuminating 3 or 5 lanes. The light distribution method is characterized in that the light emitted by a COB module LED light source is firstly refracted by a drop-shaped refraction lens (11) and then refracted secondarily by a light distribution curved surface lens (12) to achieve an optimal irradiation effect. The light distribution method provides a foundation for the use of a single COB module LED light source in an urban road, and has the advantages of low cost and high efficiency.
