摘要： A projection type display apparatus incorporating a light receiver or a light transmitter, in which the light signal is received or transmitted through a screen or condensing lens disposed in its vicinity, and hence the luminous flux utility efficiency is high. A projection type display apparatus capable of preventing deterioration of picture quality due to difference in color in the projection units, and the best picture quality is realized even when the projection lenses for different colors are composed of nearly same components.

摘要： A projection lens system has a first lens to a sixth lens which are serially arranged in this order from a screen side. The first lens has a meniscus configuration in which a convex surface is directed toward the screen side and the power of the lens changes from positive to negative from the optical axis toward a peripheral portion of the lens. The first lens has two aspherical surfaces. The second lens has a positive power meniscus configuration in which a convex surface is directed toward the screen side. Both surfaces of the second lens are aspherical. The third lens has a positive power meniscus configuration in which a convex surface is directed toward the screen side. The fourth lens is disposed close to the third lens and has two convex surfaces. The fifth lens has a positive power meniscus configuration in which a concave surface is directed toward the screen side. Both surfaces of the fifth lens are aspherical. The sixth lens has a concave surface which has a large curvature directed toward the screen side. The surface of the sixth lens on the screen side is aspherical.

摘要： Self-aligning mechanisms hold a condenser housing. The condenser housing is moved toward an integrator while tapered surfaces of the condenser housing of an LED light source unit are inserted along condenser lens guides of a projection unit. LED light source unit datum surfaces and datum surfaces of the projection unit abut against each other, and the tapered surfaces of the LED light source unit can no longer move toward the integrator along the condenser lens guides of the projection unit. In this state, the LED light source unit and the projection unit are coupled to each other.

摘要： A dichroic mirror for reflecting red light for optical separating and a dichroic mirror for reflecting red light for optical synthesizing are installed on the same plane in an image generating apparatus of the present invention. In addition, a dichroic mirror for reflecting blue light for optical separating and a dichroic mirror for reflecting blue light for optical synthesizing are installed on the same plane. Accordingly, a compact configuration can be realized. Since a main reflecting mirror is a rotating elliptic mirror and a lamp is located on a focus or around the focus, a lighting equipment which irradiates conic luminous flux can be realized.

摘要： On the incident sides of the blue light modulating liquid crystal panel and the green light modulating liquid crystal panel, condenser lenses whose outer diameter is equal to or more than that of the two liquid crystal panels are disposed respectively. No condenser lens is disposed on the incident side of the red light modulating liquid crystal panel. The focal length f of the two condenser lenses is preferably set to be a value of (L.sub.1 .multidot.L.sub.2)/(L.sub.1 +L.sub.2), where L.sub.1 is the distance between each condenser lens and the light source, and L.sub.2 is the distance between each condenser lens and the projection lens. The direct light from the discharge lamp and incident upon the condenser lenses is all incident upon the projection lens. Alternatively, a condenser lens may be disposed on the incident side of the red light modulating liquid crystal, but having a focal length which is longer than the other condenser lenses, preferably equal to L.sub.1. Therefore, an image on a screen is improved in illuminance difference between the central portion and the peripheral portion and at the same time, luminance balance of the three single color lights is improved and color shade is reduced.
