Patent number: 8721142Abstract: A novel vehicular light fixture (10) is disclosed. The light fixture (10) is compact, yet efficient, and employs semiconductor light sources (44) to produce output light in desired patterns. The fixture (10) can be used to produce fog lamps, driving lamps and other non-headlamp vehicle lighting functions. Depending upon the light output required, one or more semiconductor light sources (44) and a corresponding number of optical bodies (64) are employed in the fixture (10) to produce the desired light pattern.Type: GrantFiled: March 7, 2013Date of Patent: May 13, 2014Assignee: Magna International Inc.Inventors: Chad D. Lambert, James R. McFadden, Ronald O. Woodward, Ronald G. Hare

Publication number: 20130223088Abstract: An automotive signal light is taught which employs multi-focal length light pipes to collect, collimate and direct, as needed, light emitted from one or more semiconductor light sources. Each multi-focal length light pipe includes at least one light transmission structure, each of which has a light receiving port to receive light emitted from a semiconductor light source spaced from the light receiving port by an air gap. The light transmission structure includes at least two superimposed parabolic reflecting surfaces, each having a common focal point at the light receiving port but having different focal lengths, and the superimposed parabolic reflectors operate to receive, collimate, spread and transmit the light from the semiconductor light source to a light emitting surface of the light pipe which is located adjacent to a lens of the signal light. The aesthetic arrangement of the light pipes is not particularly limited and a wide range of signal light functionalities can be provided.Type: ApplicationFiled: March 18, 2013Publication date: August 29, 2013Inventors: Chad D. Lambert, James R. McFadden

Patent number: 8061880Abstract: A headlamp assembly which includes an optic used for providing a turn signal which meets the government requirements for luminous intensity when the turn signal is located near or next to the headlamp assembly. The present invention is a headlamp assembly which includes a housing, at least one optic disposed within the housing, as well as at least one light source which is operable with the optic such that light is emitted from the optic which meets or exceeds present regulatory requirements. The present invention also includes an outer lens mounted on the housing such that light emitted from the optic passes through the outer lens.Type: GrantFiled: August 22, 2008Date of Patent: November 22, 2011Assignee: Magna International Inc.Inventors: Chad D.

Patent number: 7806572Abstract: A headlamp assembly which employs semiconductor light sources includes an optics chamber that is isolated from the surrounding environment to prevent the ingress of water, dirt, or other foreign materials into the optics chamber. At the same time, the headlamp assembly includes a plenum chamber, separated from the optics chamber, and airflow through the plenum chamber provides the necessary cooling for the semiconductor light sources.Type: GrantFiled: March 29, 2007Date of Patent: October 5, 2010Assignee: Magna International Inc.Inventors: James R. McFadden, Chad D. Lambert

Each multi-focal length light pipe includes at least one light transmission structure, each of which has a light receiving port to receive light miffed from a semiconductor light source spaced from the light receiving port by an air gap. The light transmission structure includes at least two superimposed parabolic reflecting surfaces, each having a common focal point at the light receiving port but having different focal lengths, and the superimposed parabolic reflectors operate to receive, collimate, spread and transmit the light from the semiconductor light source to a light emitting surface of the light pipe which is located adjacent to a lens of the signal light.

Patent number: 7604383Abstract: A headlamp fixture and a control system for controlling a vehicular lighting system to produce particular lighting patterns required under different regulatory regimes is disclosed. The headlamps employ semiconductor light sources to create the desired patterns and can include at least two inclined light source elements which are alternately illuminated to produce required side illumination or can include single light source elements which can be rotated clockwise and counterclockwise to produce the required side illumination. The lighting system can employ an output from a GPS receiver to determine the country or region in which the vehicle is being driven to automatically configure the operation of lighting system components, such as the side illumination of the headlamps and/or the activation and deactivation of daytime running lights, to meet the regulatory requirements of the country or region.Type: GrantFiled: June 29, 2006Date of Patent: October 20, 2009Assignee: Magna InternationalInventors: Chad D. Lambert, Chris Wilson, Ronald Owen Woodward

Publication number: 20090237952Abstract: A modular semiconductor light source assembly includes a semiconductor light source, such as a light emitting diode, which is mounted on a substrate which supplies electricity to the light source and which assists in removing waste heat therefrom. Substantially all of the light emitted by the LED is transferred to a lens by a light pipe, the cross section of the light pipe increasing from the light source to the lens and the lens having a general D-shape such that the light pattern formed by the lens is constrained in a first direction orthogonal to a second direction. The assembly can be combined with other similar assemblies or other light sources in a light fixture to produce a desired overall beam pattern such as a automobile headlamp low beam or high beam pattern.Type: ApplicationFiled: June 3, 2009Publication date: September 24, 2009Applicant: Magna International Inc.Inventors: Chris Wilson, Chad D. Lambert, Ronald O. Woodward, Cole J. Cunnien
