Abstract

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.
