    摘要: A high brightness discharge light source having improved thermal balance characteristics includes a lamp envelope having an arc chamber formed therein and a pair of electrodes extending into opposite ends of the arc chamber so as to be displaced from one another by a distance of no greater than 4 mm. A fill disposed within the arc chamber is excited to a discharge state upon the introduction of an excitation energy coupled through the pair of electrodes. The light source is operated vertically so that one of the electrodes is disposed at the top region and the other electrode is disposed at the bottom region of the arc chamber. The arc chamber is formed having a diameter dimension which is just larger than the spacing between the electrodes, and a height dimension which is approximately twice the diameter dimension. The diameter dimension is substantially uniform along the length of the arc chamber. The uniform diameter characteristic is effective so that the thermal operating properties associated with the discharge state are substantially equally distributed from the top to the bottom regions of the arc chamber thereby resulting in extending the life of this light source to approximately 6000 hours.

    摘要: An optical coupling assembly is useful for coupling a source of light, having high brightness and being non-coherent and focussed at a focal plane, to a plurality of optical light conductors. The coupling assembly includes an elongated light transmissive coupling member which has a central longitudinal axis and is disposed between the focal plane of the light source and leading ends of the optical light conductors. The coupling member includes oppositely flared front and rear end portions and a middle portion disposed along the longitudinal axis, with the middle portion extending between and connected to the front and rear end portions. The coupling member can have either a solid or tubular configuration. The middle portion of the coupling member has cylindrical shape and cross-sectional size of uniform dimensions and being less than the respective cross-sectional sizes of an inlet end of the front end portion and an outlet end of the rear end portion. The front end portion of the coupling member can have either a frusto-conical or parabolic shape, whereas the rear end portion can have a frusto-conical or parabolic shape being oriented in the reverse of the frusto-conical or parabolic shape of the front end portion. The rear end portion has a greater axial length than the front end portion and the outlet end of the rear end portion is larger in size than the inlet end of the front end portion.

    摘要: Improved collection optics for a lighting system comprised of a light source, reflector and light receptive component include a multi-portion reflector or a non-imaging optical collector having a positive curvature located at an input end to the light receptive component. The collection optics capture additional lumens for transmission through the light guide. The optical arrangement can also collect different colors of light from the source that would otherwise be omitted from transmission through the light receptive component.
