Abstract:
A hollow light guide illumination system is provided for coupling light from an illumination source (60) to a hollow light guide (62), which is used for a variety of purposes, such as tunnels, hallways, and large rooms where direct lighting is dangerous, difficult to maintain or subject to vandalism. The illumination system employs an illumination reflector (77) which has been customized to maximize the efficiency of light transmission between the illumination source (60), such as an arc lamp, and the core of the hollow light guide (62). A method of fabricating the customized illumination reflector (77) includes mapping the radiation patterns of the particular illumination source (60) to be utilized, creating a database of those radiation patterns, and utilizing the database to generate an optimal illumination reflector (77) configuration. The computer-generated reflector (77) will virtually always be a non-conic section, because the illumination source (60) is not ideal.
Abstract:
The inventive system (68), which is used in transmitting illumination from a central source (12) to a variety of remote locations, efficiently couples the light originating from an arc lamp (12), or similar source, into a multiplicity of flexible macroscopic fibers (40, 40a). The combination of the several elements of the inventive system (68) results in a very efficient transfer of the energy of the light source (12) to the fibers (40, 40a). A first module (70) houses the arc lamp (12), and a second module (76, 78) generally houses the optics for coupling light to the flexible macroscopic fibers (40, 40a). The second module (76, 78) is thermally insulated from the first module (70), to thereby prevent high temperature from leaking from the first module (70) into the second module (76, 78).
Abstract:
An optical fiber manifold is provided for coupling light from an illumination source to a plurality of spaced, large diameter output fibers, or "light pipes", which are used for a variety of purposes, such as illuminating pools, spas, hazardous material zones, jail cells, and other applications where direct lighting is dangerous, difficult to maintain, or subject to vandalism. The manifold comprises a light converging element, which may be either a lens or a reflector, for converging light separately on each of the spaced optical fibers. The light converging element is segmented, with each segment corresponding to one of the optical fibers, and is precise enough that substantially all of the convergent light is received by the respective cores of each of the spaced output fibers, thereby minimizing light loss.
Abstract:
A piezoelectric shutter (24) is arranged in a comb pattern (26) and presents a core. The comb is provided with at least one tooth constituting the shutter, the bore being arranged with elevation allowing the displacement of the shutter by the piezoelectric effect. The device is remarkable in that it comprises at least one bimorph (14) arranged on the support, capable of being raised with respect to the support by the piezoelectric effect.

An optical pipe illumination system is provided for coupling light from an illumination source (12) to a number of output "light pipes" (89), which are used for a variety of purposes, such as illuminating pools, spas, hazardous material zones, jail cells, and other applications where direct lighting is dangerous, difficult to maintain, or subject to vandalism.

The inventive system, which is used in transmitting illumination from a central source (12) to a variety of remote locations, efficiently couples the light originating from an arc lamp, or similar source, into a multiplicity of flexible macroscopic fibers (40, 44). The combination of several elements (16, 18, 24, 24a, 28, 28a, 34, 34a, 36, 36a) of the inventive system results in a very efficient transfer of the energy from the light source to the fibers (40, 44). The system also provides a very flexible mechanical means for distributing the energy to the fibers (40, 44) and to remote locations at which the light is used.
