Cooling device, lighting device for a motor vehicle, and motor vehicle

A lighting device for a motor vehicle comprising:

• at least one lighting mechanism;
• and
• at least one cooling device, each cooling device of the at least one cooling device including:
• a heat sink having at least one heat-conducting surface, the heat sink configured to be coupled to a heat source in a heat-conducting manner;
• and
• at least two cooling fins projecting from the heat sink on a side of the heat sink facing away from a heat-conducting surface of the at least one heat-conducting surface,
• wherein each cooling fin of the at least two cooling fins includes at least one first chamber and at least one second chamber positioned further away from the heat sink than the first chamber, each of the at least one first chamber and each of the at least one second chamber being at least partially filled with a phase change material,
• wherein each cooling device is connected to one or more lighting mechanisms of the at least one lighting mechanism in a heat-conducting manner via the respective at least one heat-conducting surface either directly by the respective at least one heat-conducting surface abutting the respective one or more lighting mechanism or indirectly.
