The disclosed subject matter generally relates to a lighting device including at least two optical output modules for jointly providing transformable output light. The transformable output light is transformable a diffuse light output and a light output that has higher contrast than the diffuse light. Accordingly, the inventors realized that an enhanced user experience for vehicle occupants is provided by a lighting device that can seamlessly transform its output light between diffuse light to more high contrast light. For example, a vehicle interior component may be illuminated with a diffuse light when it is in one state, e.g. when it is not used. In a second state, when the component is used or intended to be used, it may be illuminated with a high contrast light to provide the user with more helpful assist light.

A lighting apparatus includes a light emitting diode, in which the light emitting diode includes an n-type nitride semiconductor layer, an active layer located on the n-type nitride semiconductor layer, and a p-type nitride semiconductor layer located on the active layer. The light emitting diode emits light that varies from yellow light to white light depending on an driving current.

An illumination device for a motor vehicle includes at least one light source and an elongated waveguide which is delimited along the length thereof by a lateral surface. The waveguide is configured to guide light from the at least one light source along a light propagation direction in a totally reflective manner, the light propagation direction corresponding to the length of the waveguide. The light of the at least one light source can be coupled into the waveguide via a coupling surface at an end face of the waveguide, and a decoupling structure is provided in the lateral surface of the waveguide for decoupling light, which exits the waveguide via an exit region of the lateral surface along the light propagation direction, thereby overriding the total reflection condition.
