  • Patent number: 9992458
    Abstract: A projection lens has a lens barrel holding a lens. In a case where an image forming panel is disposed to be shifted with respect to an optical axis of the projection lens, in a second part on a side to which the image forming panel is shifted with respect to the optical axis of the projection lens, there is a great increase in temperature, and in a first part on the opposite side, there is a small increase in temperature. A lens barrel heating optical section has a first mirror, condensing lenses, and a second mirror. The lens barrel heating optical section emits the redundant light, which is reflected by the color wheel, toward the first part of the lens barrel. By heating the first part through redundant light, temperature distribution in the circumferential direction becomes uniform, and deterioration in performance of the projected image is suppressed.
