Patent number: 9869441Abstract: This invention provides an optical system that collects 100% of the light emitted from the light source and effectively directs it into the desired beam pattern. This is achieved by a combination of different optical control methods including reflector and lens optics. The cost is controlled by a design that reduces the optical part count to 2 main components, which reduces manufacturing and assembling time and maintains proper alignment to the light source and system.Type: GrantFiled: November 9, 2015Date of Patent: January 16, 2018Assignee: Magna International Inc.Inventor: Ronald O.

Publication number: 20130155535Abstract: An integrated solar concentrator assembly (10) which is built to allow an opposing criss-cross optics pattern, creating a more compact, structurally sound unit having a nearly perpendicular light path into a mixing optic (32). This improves optical efficiency and allows for the mixing optic (32) to have a flat outer surface, thereby improving manufacturability. This criss-cross optical pattern also allows the opposite mirror structure to be used to support the solar receiver components, eliminating additional brackets. The configuration of the integrated solar concentrator assembly (10) allows frame mounts to be placed on the outboard corners of the assembly, improving the inherent aim accuracy, as well as simplifying installation.Type: ApplicationFiled: August 16, 2011Publication date: June 20, 2013Inventor: Ronald O. Woodward

Patent number: 7717597Abstract: A light engine for use in systems such as automotive lighting systems employs two or more semiconductor light sources, such as LEDs. Light emitted from the light sources is captured by light pipes which are mounted such that the light capturing surface of the light pipes are properly positioned, with respect to the semiconductor light sources, substantially independent of changes in the dimensions of the light pipes which may result from thermal expansion or contraction of the light pipes. The light pipes transfer substantially all of the light captured from the semiconductor light sources to light emitting surfaces of the light pipes which can be appropriately located adjacent the output optics of the lighting system. The light engine can be easily assembled as the light pipes are retained in slots on a positioning member which is mounted at a known position with respect to the semiconductor light sources.Type: GrantFiled: April 16, 2007Date of Patent: May 18, 2010Assignee: Magna International Inc.Inventors: Micheal D.
