A head lamp assembly having a main functional head lamp and a UV LED light source configured to direct UV light through a decorative accent light pipe is provided. The light pipe extends at least partially about the functional head lamp, wherein the light pipe has a phosphor coated surface to convert the UV light traveling through the light pipe into visible, luminous light. The visible light is emitted from the light pipe to provide the desired decorative appearance about the functional head lamp.

Head lamp assembly and accent lighting therefor

A method for controlling the intensity of light within an interior passenger compartment in a motor vehicle to create perceived sensations of safety, comfort and personal accommodation in conjunction with specified, night time, driving-related occurrences. The natural human desire for safety is satisfied as a driver approaches a parked motor vehicle by illuminating the interior passenger compartment with a plurality of light sources () in response to having produced a safety approach signal. The natural human desire to be comfortable within a confined space is satisfied by the act of opening the door (), whereupon the interior illumination intensity is automatically lowered to a second intensity level. Once the transmission shift selector is moved out of its Park condition, the interior light intensity is automatically decreased to a third intensity level to provide the sensation of stress reduction and thus satisfy the natural human desire to be at peace. Intermittently during the third intensity level mode, the driver or other occupants may have a task driven desire to illuminate a localized region of the passenger compartment, which is accommodated by a spot light sub-assembly () creating a directional beam of light within the passenger compartment.

Transitional lighting system for vehicle interior

A CHMSL () or other lighting system feature of an automobile () includes a feature for presenting personal expressions in the form of words or symbols but is automatically deactivated when the regular vehicle lighting system is in use. The personal expression is fixed in a tangible medium by way of phosphor-coated indicia () placed within a UV impervious housing (). A secondary UV light source () selectively energizes the phosphor-coated indicia () so that the irradiated material glows and is visible through a light transmissive screen (). The light transmissive screen () is provided with a UV blocking agent so that harmful UV rays do not escape the housing (). The phosphor-coated indicia () can be mounted on a removable transparent plate (), on light dispersion optics (), or on the inner face of the light transmissive screen (). A control circuit (&#x2033;) manages the primary light source () and the secondary UV light source () so that only one of the light sources can be energized at any one time.

Light

A reduced glare projector style headlight assembly () comprises a light source (), a reflector () and an optical lens (). An opaque mask () is positioned between the lens () and the reflector () for creating an upper shadow region in the focused beam pattern () to shield on-coming traffic. The mask () includes a transition region () proximate its top edge () for allowing a limited amount of projected light to pass through the mask (), into the upper shadow region in the focused beam pattern (). In several embodiments, the mask () is applied or otherwise affixed to a transparent substrate () which also supports the transition region (). To combat undesirable chromatic effects, a color filter () can be positioned in the light path () for disrupting selective wavelengths of light energy. As alternative approaches, the transparent substrate () and/or the lens (') can be doped with a color filtering material or composition.

A waveguide illumination assembly for an automobile license plate includes a single light source and a transport or waveguide disposed outward from the license plate perimeter. The light source shines into one end of the waveguide. The waveguide has one or more arms, each of which has an array of reflective elements. Light is internally reflected as it travels through the waveguide until it strikes a reflective element, thereby directing light through an opposing longitudinal side of the waveguide arm and onto the license plate.

Waveguide illumination assembly for an automobile license plate

A vehicle headlamp includes a beamforming waveguide having an input face, an output face, and a guide portion extending between the input face and the output face. A light source is positioned at the input face of the beamforming waveguide. A lens is positioned at the output face so that light output by the beamforming waveguide passes through the lens to provide vehicle forward illumination. The beamforming waveguide is shaped to generate a desired headlamp beam pattern and can be formed as a block of solid material, a bundle of plastic or glass fibers, or a solid molded wedge that can be moved between two positions to provide both high and low beam forward illumination.
