Abstract: A lightguide illumination system is disclosed for providing more improved and efficient technology for capturing light from an extended light source having a relatively high aspect ratio, and coupling that light into a plurality of lightguides. The inventive systems functions by dividing the length of the extended light source into shorter segments, so that the aspect ratio of the light source can be more closely matched to the aspect ratio of the lightguide. In the preferred embodiment, a plurality of interleaved trough reflector segments are employed to segment the length of the light source. This enables the coupling efficiency of the total system to be greatly improved.

Abstract: A light arrangement for a vehicle has a light source mounted in a reflector. A light disc is connected to the front end of the reflector in front of the light source.

The light signal travels through the light disc by total reflection to be then received by the receiver.

Abstract: A direct-indirect luminaire has a housing and down light passage areas in the bottom of the housing through which the direct lighting component of the luminaire is produced. Lamps mounted in the housing in proximity to the down light passage areas are shielded from any line of sight exposure by means of a laterally extending shielding element positioned between the down light passage area and the lamps. Preferably, the laterally extending shielding element extends a distance sufficient only to prevent lamp sight exposure of the lamps through the down light passage area.

Abstract: A lamp assembly adjustable between narrow beam and wide beam light distributions, the lamp assembly is particularly intended for housing lamping or the like for mounting to industrial emergency unit fixtures of differing size and conformation. At least one and preferably two of the lamp assemblies are mounted to a unit fixture in spaced relation to illuminate critical areas within an industrial or commercial space during emergency conditions, such as failure of mains power, to allow evacuation of the space. In order to illuminate the desired areas, each of the lamp assemblies can be adjusted along an internal track to allow light to be directed toward a particular location within a wide range of possible locations, thereby facilitating illumination of the most desirable area in the vicinity of the unit fixture for a particular mounting location. Additional flexibility in the delivery of illumination to a desired area is provided by adjustability between narrow and wide beams.
