Adaptive lighting system
A lighting system for a vehicle at least one primary low beam element at least a first adaptive element, a second adaptive element and a third adaptive element and a lean angle sensor generating a lean angle signal. A controller controls the plurality of adaptive elements so that the first element, the second element and third element are extinguished at less than a first lean angle, between the first and a second lean angle greater than the first lean angle illuminating the first adaptive element, between the second and a third lean angle greater than the second lean angle illuminating the first and second adaptive elements, between the third lean angle and a fourth lean angle greater than the third lean angle illuminating the second adaptive element and the third adaptive element and extinguishing the first adaptive element in response to the lean angle signal.

METHOD AND APPARATUS FOR AN ADAPTABLE VEHICLE LIGHT FIXTURE
A method and apparatus for an adaptable vehicle light fixture is provided to activate directional illumination aspects of the light fixture based upon sensed characteristics of the vehicle. The vehicle may automatically sense its position, speed, acceleration, heading and angular velocity and may command the light fixture to emit symmetric and/or asymmetric beam patterns based upon the sensed vehicle characteristics. Directional light incident upon the light fixture may also be detected to allow intensity control thereby reducing glare to oncoming traffic. A vehicle light fixture may be pre-configured with lenses and wirelessly programmed for manual and/or automatic operation that is responsive to the pre-configuration. A plurality of vehicles with light fixtures mounted thereon comprise a network of light fixtures that are manually or adaptively controlled as a group.

LED LAMP
An LED lamp includes a lamp base for insertion into a reflector of an automotive front lighting assembly; a panel extending from the lamp base with a first vertical side facing into one half of the reflector and a second vertical side into the other half of the reflector; a primary light source including a set of LED dies on each vertical side of the panel; a two-part shield including a first shield half shielding the LED dies on the first vertical side of the panel and a second shield half shielding the LED dies on the second vertical side of the panel. The two-part shield essentially has the form of a shield in a functionally equivalent filament lamp for providing a low beam. A lighting arrangement includes such an LED lamp; a reflector to receive the lamp; and an electrical interface for connecting to a controller.
Lighting device for vehicles
A lighting device for vehicles, and in particular headlamps, having a light source unit, and having a holographic unit for the generation of a given light distribution. The holographic unit has a hologram on the basis of a photo-sensitive material, onto which the holographic information is applied by means of an exposure process. The hologram is formed by a multitude of hologram segments. The hologram segments are each assigned a separate light source of the light source unit. The hologram segments serve to generate the given light distribution. Herein, holographic information is applied to the hologram segments depending on different wavelengths and different angles of the light source assigned to the hologram segments.
