Optical device and projector |
摘要 |
A projector, includes: a light source device; an optical device that modulates a light beam irradiated from the light source device in accordance with image information; and a projection optical device that projects the light beam modulated by the optical device. The optical device includes: an optical element optically converting the light beam incident thereon and emitting the converted light beam; and a heat-conducting member that is connected with the optical element in a heat transferable manner to cool the optical element. The heat-conducting member includes a heat pipe having: a tube; a capillary structure provided in the tube; and a coolant housed in the tube, the coolant circulating in the tube to transfer heat in the heat-conducting member. An optical-element-side connecting portion of the optical element to be connected with the heat-conducting member and a heat-conducting-member-side connecting portion of the heat-conducting member to be connected with the optical-element-side connecting portion are configured to be in a surface-contact when the connecting portions are connected to each other. |
