Abstract
A motor vehicle headlight lighting module comprising at least one first light source, a device for converting the wavelength of the light emitted by the first light source; and a fan able to generate a flow of air. The lighting module includes at least one first air duct and one second air duct that are separate, the fan being placed at the inlet of each of the first and second air ducts so as to distribute the flow of air between the ducts, the first light source and the wavelength converter device being disposed at the outlet of the first and second air ducts, respectively.
Claims18
A motor vehicle headlight lighting module comprising:
- at least one first light source;
- a wave converter device for converting the wavelength of the light emitted by said at least one first light source;
- and
- a fan able to generate a flow of air;
- a support to which said fan, said wavelength converter device and said at least one first light source is fixed, said support comprising one or more internal walls defining a first air duct and a second air duet separated from the first air duct by said one or more internal walls,
- wherein said fan is provided at an inlet of both of said first air duct and said second air duct so as to distribute a flow of air between said first air duct and said second air duct, and
- wherein said at least one first light source and said wavelength converter device are respectively disposed at an outlet of said first air duct and said second air duct.
