Claim 0:
1. A light irradiator comprising:
a light source including a plurality of light-emitting elements;
a heat-dissipating member thermally connected to the light source;
a drive including a drive circuit for the light source;
a housing that is rectangular and accommodating the light source, the heat-dissipating member, and the drive, the housing having
a first surface having a first side with a first dimension and a second side with a second dimension greater than the first dimension,
a second surface having the second side and a third side with a third dimension greater than the second dimension,
a third surface having the first side and the third side,
a light-emission opening to allow light from the light source to pass, the light-emission opening being in the first surface and the light source being adjacent to the light-emission opening, and
a plurality of vents, the plurality of vents including a first vent and a second vent in the second surface, the first vent being nearer the light-emission opening than the second vent and the heat-dissipating member facing the first vent, the second vent being located opposite to the light-emission opening, the drive being between the first vent and the second vent;
an axial fan at the second vent, the axial fan being configured to blow air from inside the housing to outside, the axial fan having a fan size greater than the first dimension and less than the second dimension; and
a plate at the second vent, the plate facing the axial fan with a spacing less than or equal to the first dimension between the plate and the axial fan.
