The present invention relates to a vehicle lamp illuminating apparatus, a vehicle lamp assembly comprising the vehicle lamp illuminating apparatus, and a vehicle comprising the vehicle lamp assembly. The vehicle lamp illuminating apparatus comprises a lens, a circuit board, a plurality of light emitting diode (LED) light sources disposed on the circuit board and distributed in an array, and a reflection structure disposed between the plurality of LED light sources and the lens. The LED light sources are transversely arranged in an upper row and a lower row. The reflection structure comprises a plurality of reflection mirror sets each disposed in one-to-one correspondence with two LED light sources that are vertically opposite to each other. Luminance of one or more local areas of an illuminating light pattern can be adjusted, thus implementing various illuminating light patterns and meeting a self-adaptive requirement of a headlamp.

A lighting device comprises a light-emitting module with light-emitting elements, wherein the light-emitting elements are arranged adjacent to each other and are configured to emit light towards a light-emitting side. The light-emitting module is configured such that the light-emitting elements can be addressed partially independently of each other, such that some may be brought into a switched-on state while others are brought into a switched-off state. A top layer is disposed on the light-emitting module at the light-emitting side. Further comprising a switching material capable of a reversible change in transmittance for the light emitted by changing to a higher transmittance in regions where the top layer situated on light-emitting elements in the switched-on state or to a lower transmittance in regions of the top layer situated in the switched-off state. The invention further refers to methods for producing and operating a lighting device and using a lighting device.

A first pixel with a first pixel sidewall is disclosed. A second pixel with a second pixel sidewall facing the first pixel sidewall is also disclosed. A first dynamic optical isolation material between the first pixel sidewall and the second pixel sidewall and configured to change an optical state based on a state trigger such that a light behavior at the first pixel sidewall for a light emitted by one of the first pixel and the second pixel is determined by the optical state, is also disclosed.

Disclosed is a vehicle lamp a pair of lamp modules configured to irradiate light to form a pair of left and right light distribution patterns. Each of the lamp modules includes first and second lamp units. Further, irradiation light from the first lamp unit forms a first light distribution pattern having a vertically extending cutoff line at a center side of a pair of left and right distribution patterns, and irradiation light from the second lamp unit forms a second light distribution pattern near the cutoff line. The second light distribution pattern is smaller and brighter than the first light distribution pattern.
