A lamp comprising:
- a light emitting element;
- a heatsink thermally coupled to the light emitting element and configured to surround a volume of space;
- a fan element configured to produce an airflow and direct the airflow towards the heatsink;
- a covering element configured to cover the volume of space surrounded by the heatsink so as to close the volume of space at an end proximate to the fan element;
- and
- a coupling element configured to couple the fan element to the heatsink;
- wherein the fan element comprises:
- a fan configured to produce the airflow;
- a fan housing configured to house the fan;
- and
- a fan coupling element configured to couple the fan housing to the coupling element;
- wherein:
- the fan coupling element comprises one or more protrusions configured to extend towards the heatsink along an axis (X) of the volume of space;
- and
- the coupling element is configured to couple to the fan coupling element at each of the one or more protrusions.
