| Title: |
Light Source Device |
| Abstract: |
A light source device equipped with a concave reflector having an open
front end section. Installed in the light source device is a light source
having a light emitting unit. The unit is positioned on a focal point of
the reflector. A cover is attached to the open front end section of the
reflector to cover the open front end section. The cover has an air
inflow opening provided at a side section thereof in relation to the open
front end section. At least a part of the cover is made of a transparent
material. The part is a light passage through which light emitted by the
light source and reflected by the reflector passes. The light source
device is further equipped with a fan having an air outflow opening. The
fan is provided so that airflow created by the fan and blown through the
air outflow opening is directed to the air inflow opening of the cover,
without obstructing the light passing through the light passage. An air
control unit is provided between the air outflow opening of the fan and
the air outflow opening of the cover. The air control unit controls the
airflow blown through the air outflow opening of the fan so that it is
flown into the reflector through the air inflow opening of the cover and
directed at least to one specific section of the light source, thus
cooling the specific section.
