摘要： An illumination apparatus includes a red light valve, a green light valve, a blue light valve, a polarization adjustment element, and a color combiner. The polarization adjustment element adjusts polarization of fourth color component light. The color combiner combines light emitted from the red light valve, the green light valve and the blue light valve. Superimposed component light which is any one of a red component light, a green component light and a blue component light enters the polarization adjustment element together with a fourth color component light. The polarization adjustment element transmits the superimposed component light without adjusting the polarization, and transmits the fourth color component light with adjusting the polarization. The superimposed component light and the fourth color component light emitted from the polarization adjustment element enter a specific light valve corresponding to the superimposed component light, among the red light valve, the green light valve and the blue light valve.

摘要： Projection display apparatus 100 is equipped with a cooling device 300, which comprises an air passage as the passage of the air and a heat absorber that cools off the air flows in the air passage, and a light source controller 220, which controls the amount of light irradiated on the optical elements (liquid crystal panel 50 and the like). The optical elements are provided in the air passage. When the heat absorber receives an operation termination instruction to terminate the operation of the apparatus itself, it will end the cooling of the air flowing in the air passage. the light source keeps emitting the light, even in a case of receiving the operation termination instruction.

摘要： An image projecting unit of a projector includes a light source; a polarization control element which controls a polarization direction of light emitted from the light source; and a projecting unit which projects the image light that passed through the optical modulation element. The control unit detects a deterioration state of the polarization control element based on the projected image which is taken by an image-taking unit when a test image representing a single color throughout a screen is projected.
