  • Patent number: 8646960
    Abstract: A backlight includes a light guide and a first and second light source adapted for independent operation and arranged to inject a first and second light beam, respectively, into the light guide through different portions of the light injection surface. Each light source includes a lamp and a concave reflector to partially collimate light from the lamp. One major surface of the light guide includes prismatic structures that are parallel to a first axis. Another major surface of the light guide includes lenticular structures that are parallel to each other but perpendicular to the prismatic structures. The lenticular structures limit spatial spreading for light that remains in the light guide. Each light source cooperates with the light guide to provide light that is substantially laterally confined to a transverse band of the light guide, even though the light guide contains no gaps that define slats to accomplish such confinement.

A tapered internal surface abuttingly engages the seal member and provides for centering of the seal member relative to the leg. A separate tapering region, shoulder, or stop surface limits insertion of the seal member into the leg opening for precision location of the seal member, and in another embodiment, a single continuous taper inside the leg cooperates with a tapered seal member for both centering and precision insertion of the seal member into the leg. In another embodiment, a hybrid electrode is employed where one portion of the hybrid electrode is electrically non-conductive and a second portion of the electrode is electrically conductive.
