Abstract
In an illuminating apparatus for a projection display, light from a plurality of light sources converge at a respective focal point that coincides with an input side of a corresponding light pipe integrator. The light pipe integrators convert the light incident on the input sides thereof into evenly distributed light that are radiated at output sides thereof and that pass through a principal condenser lens before reaching a plane of a liquid crystal display panel of the projection display.
