Patent number: 9690177Abstract: A lighting device includes a supporting section configured to support a light source device unit, a fan housing section in which an outflow port for causing the air discharged by a cooling fan to flow out is formed, and a circulating device supported by the light source device unit. The outflow port is opened in a direction along a second direction. The light source device unit includes an inflow port opened to a side opposed to the outflow port and a channel for leading the air flowing in from the inflow port to a light source. The circulating device includes a moving section disposed between the light source device unit and the fan housing section in a predetermined position, a ventilation hole for causing the outflow port and the inflow port to communicate being formed in the moving section, and an urging section configured to urge the moving section.Type: GrantFiled: June 20, 2016Date of Patent: June 27, 2017Assignee: Seiko Epson CorporationInventors: Yukihiro Horiko, Takahiro Miyata, Takahiro Takizawa
