Abstract
A floodlight includes a light source, a support member that supports the light source, and a fan that cools the light source by generating an air flow on a surface of the support member. The light source is supported on a front face of the support member and emits light forward with respect to the support member. The fan is disposed rearward of the support member, at a position facing the support member.
Claims26
A floodlight comprising:
- a housing having an internal space;
- a wall that partitions the internal space into a first internal space and a second internal space, and has an opening that connects the first internal space and the second internal space;
- one or more first vents that connect the first internal space to an external space;
- a second vent that connects the second internal space to the external space;
- a support member in the first internal space;
- a plurality of fins that protrude rearward from the support member, the fins each having a plate-like shape extending in a first direction on a predetermined plane that is in parallel with a rear face of the support member, the fins being arranged in a second direction on the predetermined plane that perpendicularly intersects with the first direction;
- a light source in the first internal space and supported by a front face of the support member, the light source emitting light forward with respect to the support member;
- and
- a fan in the second internal space and that cools the light source by generating an air flow on a surface of the support member, the fan being disposed rearward of the support member, at a position facing the support member via the opening.

A floodlight comprising:
- a heat-radiating member;
- a light emitter unit including a light source and a control board that supports the light source, the light source being supported on a front face of the heat-radiating member and emits light forward with respect to the heat-radiating member;
- a fan that cools the light source by generating an air flow on a surface of the support member, the fan being disposed rearward of the heat-radiating member, at a position facing the heat-radiating member;
- a housing that has an internal space in which the light emitter unit, the heat-radiating member, and the fan are housed, the housing including vents that connect an internal space to an external space of the housing, at least a part of the heat-radiating member being exposed via the vents, the vents including a first vent on a first side face of the housing, and a second vent on a second side face of the housing;
- and
- a plurality of fins on the heat-radiating member, the heat-radiating member being in contact with the control board, the fins each having a plate-like shape extending in a first direction on a predetermined plane that is in parallel with a rear face of the heat-radiating, the fins being arranged in a second direction on the predetermined plane that intersects perpendicularly with the first direction.
