Lighting device for mounting to an optical element having a mounting ring, heat sink with a hollow structure and fan

A method of manufacturing a lighting device, the method comprising:

• providing a metal structure;
• forming, from the metal structure, a heat sink that comprises a lighting module mounting part configured for connection with at least one lighting module and at least one hollow structure within the heat sink;
• providing a center ring having a first side and a second side opposite the first side, the center ring comprising a mechanical interface configured for mechanically coupling the center ring to the optical element;
• mounting the center ring to the heat sink so that the at least one hollow structure is positioned entirely over the first side of the center ring;
• providing the at least one fan comprising at least one blade and a driver;
• and
• mounting the at least one fan so that at least a portion of the at least one fan is contained within the at least one housing part with the at least one blade disposed within the at least one hollow structure.

An automotive lighting device comprising:

• an optical element comprising a socket;
• and
• a lighting device comprising:
• a center ring having a first side and a second side opposite the first side, the center ring comprising a mechanical interface configured for mechanically coupling the center ring to the optical element,
• a heat sink comprising a lighting module mounting part configured for connection with at least one lighting module and at least one hollow structure within the heat sink,
• at least one housing part, and
• at least one fan comprising at least one blade and a driver, at least a portion of the at least one fan contained within the at least one housing part with the at least one blade disposed within the at least one hollow structure,
• the lighting device mounted in the socket in the optical element via at least the center ring with all components of the light device disposed within the optical element.
