| 发明名称 | Projector having a turbulent flow plate disposed between a light modulator and a polarizer | ||
| 摘要 | A projector includes a light source unit, a light modulator that modulates light exited from the light source unit, a polarizer or a wave plate provided on a light incident side of the light modulator, a cooling unit that supplies cooling air to the light incident side of the light modulator, and a turbulent flow plate disposed between the light modulator and the polarizer or the wave plate in a path along which the cooling air from the cooling unit flows toward a light incident surface of the light modulator, the turbulent flow plate having a fin that tapers from a base end toward a tip. | ||

| 主权项 | 1. A projector comprising: a light source unit; a light modulator that modulates light exited from the light source unit; a polarizer or a wave plate provided on a light incident side of the light modulator; a cooling unit that supplies cooling air to the light incident side of the light modulator; and a turbulent flow plate disposed between the light modulator and the polarizer or the wave plate in a path along which the cooling air from the cooling unit flows toward a light incident surface of the light modulator, the turbulent flow plate having a fin having a shape that tapers from a base end toward a tip, wherein the turbulent flow plate is disposed such that at least part of the fin is shifted to the windward of the cooling air from the light incident surface of the light modulator. | ||
