A lighting device for vehicle interior lighting including at least one dimmable light source, a current driver supplying the at least one dimmable light source with a control current and a microcontroller to determine a dimming value for dimming the at least one light source corresponding to a dimming request signal and to transfer this to the current driver. The at least one light source has a brightness, which corresponds to the control current. The current driver is to set the control current for supplying the at least one light source corresponding to the dimming value so that the at least one light source assumes the brightness corresponding to the dimming value. The microcontroller is to determine the dimming value as a new dimming value based on a current dimming value and a dimming value change. The dimming value change is based on the dimming request signal.
A lighting device for vehicle interior lighting, comprising:
A method to dim a lighting device for vehicle interior lighting including at least one dimmable light source and a current driver for supplying the at least one dimmable light source with a control current with which the at least one dimmable light source has a brightness that corresponds to the control current, wherein the method comprises:
