A multifunction lamp unit for a vehicle includes a housing, at least one light conductor with at least one illuminant provided by an LED on a printed circuit board, at least one light foil, and a clear lens. A method for manufacturing lamps for vehicles includes producing a housing, a light conductor, and a clear lens as one unit out of plastic in a 3-component injection procedure.

The present utility model discloses a light guiding device and a vehicle lamp. The light guiding device includes a light guide medium component configured to allow light to be transmitted through it from one end thereof to another end thereof. A light guide fixing component is arranged on the light guide medium component and configured to fix the light guide medium component, wherein the light guide medium component and the light guide fixing component are both at least partly made of a transparent material. The light guide fixing component has a light directing portion configured to direct the light leaked from the light guide medium component into the light guide fixing component to exit the light guide fixing component away from a predetermined direction. Using the light guiding device and the vehicle lamp according to the present utility model can prevent light exiting the light guide fixing component from forming undesirable light spots in an undesirable direction.

The invention proposes a light device casing formed by a wall made of an electrically insulating material, such as a polymer. The casing includes an inner surface forming a housing receiving a light module with a light-emitting diode and a light guide. The inner surface includes a zone reflecting light from the light module out of the casing, and a fixing zone for a control module of the light module. The light device includes a reflecting and electrically conductive coating, which covers both the reflecting zone and the fixing zone. The aluminum coating is cost-effective since it is applied in one step, and it ensures two functions, namely a reflection and a protection against the electromagnetic field.

A vehicle lighting system includes a light source, a first light guide, and a second light guide. The light source is arranged to emit light into the first light guide, which emits incident light from the light source into the second light guide. The second light guide is arranged to emit incident light from the first light guide. The second light guide has a light input surface arranged to receive the incident light from the first light guide, and a light output surface arranged to emit the light received through the second light input surface. The light output surface comprises a first light emitting surface section in a first plane and a second light emitting surface section in a second plane, wherein the first plane and the second plane are arranged at a first angle in relation to each other.

A vehicle lamp includes a light source and a light guide body configured to guide light from the light source therein and emit the light toward a front side of the lamp. The light guide body includes a first rod-shaped light guide portion configured to guide light incident from an incident end surface, a second rod-shaped light guide portion configured to guide the incident light, and a plate-shaped light guide portion formed in an area between the first rod-shaped light guide portion and the second rod-shaped light guide portion. The plate-shaped light guide portion has an end side surface configured to totally reflect at least a portion of light, which travels in the plate-shaped light guide portion, toward the first rod-shaped light guide portion and/or the second rod-shaped light guide portion.

The invention relates to a lighting device for a motor vehicle, comprising a light guide for the totally reflecting guidance of light from two light sources along a light propagation axis, wherein the light from one light source can be coupled in at an in-coupling face on one end face of the light guide and the light from the other light source can be coupled in at another in-coupling face on another end face of the light guide. The light guide also has an out-coupling face arranged along the light propagation axis for coupling the light out, which light exits from the light guide at an exit face arranged along the light propagation axis where the total reflection condition is removed. The lighting device according to the invention is characterized in that the light guide is designed in such a manner that the light intensity distribution of the light from at least one light source exiting at the exit face has a gradient in the propagation direction of the light from the light source concerned, and a control device for the light sources (is provided in such a manner that, when the lighting device is switched on, the light sources are activated at a predefined switch-on time interval and thereby the brightness of at least one light source is modified on the basis of a ramped or stepped progression until a predefined brightness value is achieved.

A vehicle lighting unit can increase the light emission region of a light guiding lens to improve the aesthetic feature as the lighting unit when emitting light. The vehicle lighting unit can include an LED serving as a light source and a light guiding lens configured to guide the light from the light emitting element while totally reflect the light which are housed within a lighting chamber defined by a housing and an outer lens that can cover an opening of the housing. The light guiding lens has an aesthetic portion having a rear surface in part of which cuts are formed to cause the light to exit thereby. The aesthetic portion can further have a cut formed in a front surface where no cut is formed in the rear surface thereof.

A vehicular lighting apparatus is relatively small, low cost, superior in mountability, and offers a superior design. The vehicular lighting apparatus attachable to a front end of a vehicle includes: a composite lens element that is a light guide element constructed by molding a translucent resin substantially into a plate-like shape; a planar light-emitting unit that emits illumination light; an optical system that transforms planar light from the light-emitting unit into linear light and that causes the linear transformed light to be incident on a rear side face of the light guide element; and a diffraction lens formed on the rear side face of the light guide element on which the linear transformed light is incident, and condensing the linear transformed light. The light condensed by the lens means is emitted from a front side face of the light guide element onto a road surface in front of the vehicle.

A vehicle light installed in a vehicle includes: a main case having a front opening; a first light guide disposed in the main case; a first light source that emits light into the first light guide; and a headlamp disposed in the main case. The first light guide (i) is rod-shaped, (ii) includes a first extended section extending from the inboard side of the first light guide relative to the vehicle widthwise direction toward the outboard side and a second extended section that continues from the first extended section, curves back inwardly, and extends to the inboard side, and (iii) opens toward a longitudinal center line of the vehicle. The headlamp is disposed between the first extended section and the second extended section. The first extended section and the second extended section extend toward the longitudinal center line of the vehicle to a point beyond the headlamp.
