    摘要： In optical equipment, such as a liquid crystal projector, a discharge lamp supplies light through a light valve device to project a light beam on a screen. A cooling system is provided to cool the light valve device, including a ventilation device, such as a centrifugal fan, for drawing in air through an air intake opening in the case of the optical equipment and an air flow path for supplying the drawn in air to the light valve device along plural paths. For this purpose, guide members are provided in the air flow path to divide and direct the air flow to individual parts of the light valve device along the plural paths.
