Abstract: A phosphor wheel unit includes a phosphor wheel that converts incident light into fluorescent light and emits the fluorescent light, a first heat exchanger having a plurality of fin members that is arranged and an airflow inlet surface through which an airflow generated by rotation of the phosphor wheel partially or entirely flows in, and a regulating member that regulates a direction of the airflow. The direction of the airflow regulated by the regulating member and a direction perpendicular to a rotation shaft of the phosphor wheel form an angle of between 0 degrees and 45 degrees on a surface perpendicular to an extending direction of a base material of the phosphor wheel. The airflow inlet surface is disposed intercepting the direction of the airflow regulated by the regulating member. The first heat exchanger cools a gas forming the airflow and the cooled gas returns to the phosphor wheel.

Abstract: The light source device includes a first light source, a second light source, and a substrate including a base member. A first wiring and a second wiring are disposed on the substrate. The first wiring has a connection part including connection parts such that the first light source is electrically connected in series and a connection part including connection parts such that the second light source is electrically connected in series. The base member is provided with at least one through-hole at each portion where the connection parts of the connection parts are disposed, and includes a protrusion in a vicinity of the through-hole such that the protrusion protrudes along a surface of the base member in a direction intersecting the first wiring. The second wiring includes at least one detour path in a vicinity of the protrusion, detouring around the through-hole with an insulation distance from the through-hole.

Abstract: A projection image display device includes: an optical element that separates incident light into a first color light beam and a second color light beam, synthesizes the first color light beam and the second color light beam to generate synthetic light, and emits the synthetic light; a first display panel that reflects and modulates the first color light beam; a second display panel that reflects and modulates the second color light beam; a first heat dissipator that dissipates heat of the first display panel; a second heat dissipator that dissipates heat of the second display panel; a light shielding portion that blocks a part of the second color light beam reflected by the second display panel from traveling toward the first display panel; a light shield heat dissipator that dissipates heat of the light shielding portion; and a container. The second heat dissipator is disposed outside the container.
