Abstract
A luminaire for back lighting a flat panel display in accordance with the present invention includes a fluorescent lamp having multiple lamp sections and a stack of optical components. A light guide is positioned between the fluorescent lamp and the stack of optical components. The light guide includes a first section extending across a width of the luminaire which separates the multiple lamp sections from the stack of optical components and which is adapted to substantially uniformly distribute light from the multiple lamp sections toward the stack of optical components. The light guide also includes multiple leg sections each adapted to protrude from the first section of the light guide to positions between adjacent lamp sections or to positions between one of the lamp sections and a side wall. The multiple leg sections of the light guide redirect light from the lamp sections into the first section of the light guide.
