Abstract: An illumination device and methods of forming illumination devices having a limited number of white light light emitting diodes (LED's) or solid state lighting (SSL) devices and a color filtering lens or light manipulator disposed over the white light LED to manipulate at least one of a chromaticity, a color temperature value, and a color rendering index (CRI) value of light emitted beyond the illumination device to satisfy regulatory visibly and/or illumination requirements with a more efficiently operable illumination device.

Abstract: A marine lamp includes an LED and a heat sink that removes heat from the LED. A lens assembly is associated with the LED and collects the energy from the LED and compresses the light into a high intensity beam. The beam strikes a secondary reflective surface which spreads the light into a desired output distribution. In one particular application, the desired output distribution has a ring-like distribution with a primary light beam at approximately 60 degrees from mounting surface normal.

Abstract: A ring generating LED lamp includes a lens section which employs internal reflection to direct the light energy from a hemispherical emitter into a ring shaped output distribution. The ring shaped distribution projects above and below the plane of the LED source. The lens has multiple internal surfaces that direct light from the LED source to provide a ring shaped output distribution.

Abstract: A surface mount LED lamp includes a central first section having a flat circular window that provides a direct view window to the source energy and having an angle equal to the total intended output viewing angle of the LED lamp thereby providing a smooth and relatively undistorted output intensity distribution. The window allows the energy from the wide angle LED source to exit the lamp with minimal distortion, creating a smooth generally cosine shaped light distribution through the intended viewing angle of the device. A second outer section has both refractive and internally reflective surfaces for the purpose of collecting the wider output angle light from the LED source thereby adding to the intensity at the outer edges of the distribution.

Abstract: A device having an inner surface with a combination of reflective and refractive surface facets swept about an axis of revolution perpendicular to the optical axis of the device. The outer surface has a non-planar, non-circular, non-spherical shape. This outer surface generates an appropriate intensity distribution in a direction generally parallel to the major axis of the output rectangle and may also distribute energy generally parallelly to the minor axis of the output rectangle as well.

Abstract: A light transforming method and device that includes a lens having one or more specifically shaped surfaces designed to generate an output image by directing the appropriate amount of electromagnetic energy from a substantially collimated beam to the required regions of the output image for the purpose of recreating the output image. The lens has one or more non-imaging radiant energy distribution surfaces that is of a non-uniform. shape.

Abstract: A device for creating a predetermined light output distribution having a substantially rectangular shape in angle space is provided having a lens with a revolved inner surface and a complex outer surface. The inner surface has a combination of reflective and refractive surface facets swept about an axis of revolution perpendicular to the optical axis of the device. The outer surface has a non-planar, non-circular, non-spherical shape. This outer surface generates an appropriate intensity distribution in a direction generally parallel to the major axis of the output rectangle and may also distribute energy generally parallelly to the minor axis of the output rectangle as well. The optical efficiency improvement in the design of this improved preferably LED-based product has several direct benefits including; increased reliability, lower operating temperature, reduced electrical requirements, greater product life and significantly reduced cost as compared to existing LED products.

Abstract: A light transforming method and device that includes a lens having one or more specifically shaped surfaces designed to generate an output image by directing the appropriate amount of electromagnetic energy from a pseudo-collimated beam to the required regions of the output image for the purpose of recreating the output image. An LED is collimated to produce the minimum spot size at the projection plane reasonably achievable and the pseudo-collimated light source impinges on the image shaping lens surface(s) such that the light is redistributed in correct proportion and angle to generate the predetermined output image. The image generating surface of the present invention is defined by a multitude of triangular facets that define a free-form surface shape such that when the energy distribution pattern exits the free-form surface the output image closely resembles the required output distribution pattern.
