A vehicle lighting system for a vehicle includes an accessory module assembly that is adapted for attachment to an interior portion of a vehicle and configured to illuminate, for example, an area inside the vehicle. The module assembly includes a single high-intensity power light emitting diode that has a luminous efficiency of at least about 1 lumen per watt when the light emitting diode is operated and is preferably operated at a forward current of at least 100 milliamps. The system also includes a voltage conversion element for converting the battery/ignition voltage of the vehicle to the forward operating voltage of the light emitting diode.

The invention provides a light module (1) with a light source (2) for emitting a beam of light (5), an adjustable optical element (300) for adjusting the beam of light (5) from the light source (2) into an adjusted beam of light (25) with a scattering pattern that is electrically variable; and a controller (304) for controlling, in response to an adjusting control signal (371), at least one element of a group of elements comprising the adjustable optical element (300) and the light source (2) by means of at least one driving signal (375, 376).

A lighting assembly (10) is adjustable between flood and spot lighting conditions for selectively illuminating an interior passenger compartment in a motor vehicle. The assembly (10) includes a housing (16) which clamps to a supporting member, such as a headliner (12), via a sleeve (18) interacting with a rotary cam lock (22). An LED light source (26) is orbitally supported within the housing (16) for projecting light in a directionally adjustable manner. A lens (50) is disposed in the light path (28) and is moveable between an extended spot position for task lighting and a retracted flood position for general illumination within the interior compartment. A switch (74) is responsive to movement of the lens (50) into its spot position for automatically energizing the LED (30). The switch (74) opens, thus de-energizing the LED (30) when the lens (50) is returned to its flood condition. A lighting control circuit (78, 78′) is responsive to an override signal, such as from a door switch (80, 80′), for independently activating the light source (26) when the lens (50) is in its flood position. The light source (26) is supported for orbital movement within the housing (16) by a gimbal mechanism which includes an inner gimbal (38) carried in a cross (40). Pintals (42, 44) establish intersecting perpendicular axis (A,B) to accomplish the orbital movement. A latch mechanism (64) cooperates with leaf springs (62) by controlling movement of the lens (50) between its flood and spot conditions by a repeated push impulse applied by the finger of an operator. The switch (74) is incorporated into the leaf springs (62).

An interior trim component for a vehicle includes a main body having an exterior surface for facing the interior of the vehicle. The body defines an internal cavity formed therein and an opening in the exterior surface. The cavity and the opening are in communication with each other. A source of light is mounted in the cavity such that the source of light is hidden from direct normal viewing within the interior of the vehicle.

A vehicular touch switch activated LED illumination circuit includes a LED illumination source for providing vehicle illumination. A touch switch antenna senses a user input for activating and deactivating the LED illumination source. An integrated circuit mounted to a printed circuit board for controlling the current provided to the LED illumination source. The integrated circuit is in communication with the touch switch antenna for detecting the user input. A driver circuit is mounted to the printed circuit board and is electrically coupled to the LED illumination source for driving the LED illumination source. The integrated circuit includes a battery voltage sensed input and a temperature sensed input for receiving sensed input signals to control a signal input to the driver circuit for variably controlling the current provided to the illumination source.

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 (18, 20, 22) 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 (28), 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 (22) creating a directional beam of light within the passenger compartment.

The invention is related to a rear view mirror formed by a plastic glass structure and mirror housing. The plastic glass allows smooth edges and a bezel free appearance of the mirror. The plastic glass allows in addition to shine through the mirror body to create different types of illumination in the passenger's cabin.

A light-emitting device comprises: a substrate that holds one end of connection terminals and on which is mounted an electronic component; a light-emitting element that is mounted on one face of the substrate; a support member on which the substrate is mounted; and a cover section that positionally locates and holds the substrate, by mounting on the support member in a condition abutting one face of the substrate. The cover section has a cover section body that covers one face of the substrate; on the cover section body, a light guide is provided, through which passes the light that is emitted from the light emitting element, in a condition in which movement thereof is restricted along directions on either side of the substrate.
