Abstract: The color temperature of light emitted by a luminaire having a hollow prismatic light guide is varied to counteract aesthetically undesirable reddening gradient of the emitted light. Reddening is caused by the light guide's dielectric material, which absorbs blue light rays such that proportionately more red than blue rays are guided to the light guide's far end than to points near the guide's light input end. Flare light rays which escape through the light guide near its light input end are color filtered and reflected back into the light guide. The filter color lies within a CIE-1931 chromaticity diagram {4800° Kelvin; 570 nm; 600 nm} color gamut triangle. Color filtering absorbs blue flare rays as a function of distance along the guide, imparting a near-end reddening gradient to the emitted light in inverse proportion to the far-end reddening gradient, giving the emitted light a constant apparent color, independent of distance along the guide.

Abstract: To replace an old lamp unit, first, resilient projections are pushed outward through engaging holes of a resin frame with some tool and the lamp unit is pulled out through a lamp unit guide hole. Then, a new lamp unit is inserted with the resilient projections deformed to the lamp side by utilizing their resiliency. When the lamp unit is inserted to the regular position, the projections are opposed to the respective engaging holes of the resin frame and return to their original shapes because of their resiliency to go into the respective holes. As a result, the lamp unit is positioned with respect to the resin frame and fixed to the latter. Even when external impact acts on the liquid crystal display device, the lamp unit does not fall off.
