Abstract
The present application discloses a surgical lamp. The surgical lamp includes a light source, a housing, and a heat sink into which heat from the light source is transferred. The housing includes a thermal insulating shell substantially surrounding the heat sink, and a plurality of ports that enable to airflow to dissipate the heat transferred to the heat sink.
Claims24
A surgical lamp, comprising:
- a light source;
- a heat sink into which heat from the light source is transferred;
- a housing, comprising:
- a front portion configured to emit light from the light source;
- a back portion opposite the front portion;
- a thermal insulating shell substantially surrounding the heat sink;
- and
- a plurality of ports that enable airflow to dissipate the heat transferred to the heat sink;
- a circuit board configured to drive the light source, the circuit board disposed between the heat sink and the back portion of the housing;
- a plurality of pathways configured to direct the airflow and the heat around the circuit board;
- and
- a spacer connected to the heat sink,
- wherein the spacer is configured to direct the heat to an outside of the circuit board,
- wherein an inner wall of the housing comprises a plurality of flutes that at least partly define the plurality of pathways and direct the heat transferred to the heat sink towards the back portion of the housing, and
- wherein the circuit board comprises a plurality of through holes that define an additional plurality of pathways that direct the heat transferred to the heat sink towards the back portion of the housing.
