1. An illumination apparatus, comprising:
a light source assembly,
a circuit board,
a fin assembly,
a casing, and
a fan;
wherein
the light source assembly is in electrical connection with the circuit board;
the fan is configured to generate a flowing airflow;
the fin assembly comprises a plurality of fins arranged at intervals in a configured direction;
the plurality of fins each has a first thermal connection end and a second thermal connection end arranged oppositely to each other, as well as a first thermal dissipation end and a second thermal dissipation end arranged oppositely to each other;
a connection line connecting the first thermal connection end and the second thermal connection end is defined as a first connection line;
a connection line connecting the first thermal dissipation end and the second thermal dissipation end is defined as a second connection line;
the first connection line and the second connection line forms an angle;
the light source assembly is in thermal connection with the first thermal connection end, and the circuit board is in thermal connection with the second thermal connection end;
the airflow generated by the fan is enabled to pass through the fins and flow out from the first thermal dissipation end and the second thermal dissipation end to drive a heat of the first thermal connection end and the second thermal connection end out of the fin assembly;
the casing defines therein first air inlets and air outlets passing through a casing wall;
the first air inlets are arranged perpendicular to a plane formed by the first connection line and the second connection line;
the first air inlets communicate with gaps among blades of the fan;
the air outlets communicate with the first thermal dissipation ends and the second thermal dissipation ends;
the connection path between the first air inlets and the gaps among the blades linearly extends along the direction of the first connection line; and
both the connection path between the air outlets and the first thermal dissipation ends and the connection path between the air outlets and the second thermal dissipation ends extend along the direction of the second connecting line.
