Abstract
The lighting device for a vehicle has two light sources and a wavelength conversion device excited by the combination of the radiations from the two light sources. A first light source is associated with a scanning system projecting, by scanning, a first light radiation onto a first conversion region of the device, while a second light source with semiconductors emits a second light radiation into a second conversion region of the device. The second source, different from the first source and whose luminance level is typically less high, is provided with light-emitting units of submillimetric dimensions. The beams produced by the device respectively in the first region and in the second region have different characteristics and complement one another to produce one or more lighting functions.
Claims20
Lighting device for a vehicle comprising:
- a wavelength conversion device;
- a first light source emitting a first light radiation;
- a scanning system receiving the first light radiation and projecting it by scanning onto a first conversion region of the wavelength conversion device;
- a second light source emitting a second light radiation and which includes:
- a light source with semiconductors comprising light-emitting units of submillimetric dimensions,
- wherein the wavelength conversion device is configured to emit
- a first light beam from an interaction, in the first conversion region, of the first light radiation with the wavelength conversion device, and
- a second light beam from the interaction, in a second conversion region of said wavelength conversion device, of the second light radiation with the wavelength conversion device.
