Patent number: 6454937Abstract: A water disinfection system includes a housing having a plurality of risers 207 therein for directing independent columns of water from a manifold at the bottom of the housing. An ultraviolet light source 214 is disposed above the risers to treat the water flowing therein. The UV light source may also be in the form of a fiber optic system (FIG. 4) or a mercury arc lamp including a parabolic reflector 64. Each of the risers can also include notches 304 (FIG. 9) for inducing turbulence to the water flowing thereover in order to ensure that all of the microorganisms receive ultraviolet light. The water flow rate and the light intensity may be adjusted to accommodate different levels of water contamination.Type: GrantFiled: October 20, 2000Date of Patent: September 24, 2002Assignee: Remote Source Lighting International, Inc.Inventors: Isaac Horton, Andrew P. Riser, Kurt Garrett, John F. Forkner

Patent number: 6196709Abstract: 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.Type: GrantFiled: January 29, 1999Date of Patent: March 6, 2001Assignee: Remote Source Lighting International, Inc.Inventors: Andrew P. Riser, Ronald Rykowski

Patent number: 6086234Abstract: A light guide illumination system, which is used in transmitting illumination from a central source to a variety of remote locations, comprises an illumination source, a configuration of transfer lenses disposed around the illumination source, which are each adapted to focus emitted light from the illumination source in a generally outward direction from the illumination source, a plurality of condenser lenses, and at least one light guide. Each of the plurality of transfer lenses are adapted to focus light into a corresponding condenser lens, and the at least one light guide is adapted to receive light from the condenser lenses. The combination of the several elements of the inventive system results in a very efficient transfer of the energy of the light source to the fibers.Type: GrantFiled: April 28, 1997Date of Patent: July 11, 2000Assignee: Remote Source Lighting International, Inc.Inventors: Andrew P. Riser, Ronald F. Mathis, John F. Forkner

Patent number: 6070985Abstract: A light guide illumination system having a metal-halide double-ended illumination source is disclosed. The light guide illumination system includes at least one light guide and two curved reflectors disposed in proximity to the double-ended illumination source. The two curved reflectors are adapted to reflect the emitted light from the double-ended illumination source into the light guide. The light guide illumination system further includes at least one multi-sectored lens adapted to receive light from the light guide, and at least one output light guide. The multi-sectored lens is adapted to receive the reflected light from the light guide and to focus the light into the output light guide.Type: GrantFiled: March 4, 1997Date of Patent: June 6, 2000Assignee: Remote Source Lighting International, Inc.Inventors: Andrew P. Riser, Ronald F. Mathis, David H. Liu

Patent number: 6027237Abstract: The present invention discloses an air duct for directing air onto an optical fiber bundle coupling. The air duct is used to siphon a portion of an air stream, which is used to cool an arc lamp, to the coupling end of the light guide bundle. After the air from the air duct cools the coupling of the light guide bundle, the air is routed back to provide additional cooling to the arc lamp.Type: GrantFiled: March 17, 1997Date of Patent: February 22, 2000Assignee: Remote Source Lighting International, Inc.Inventors: Andrew P. Riser, Kyle P. Lucas

Patent number: 5911020Abstract: The inventive system, which is used in transmitting illumination from a central source to a variety of remote locations, efficiently couples the light originating from a lamp, or similar source, into a multiplicity of flexible macroscopic fibers. The combination of the several elements of the inventive system results in a very efficient transfer of the energy of the light source to the fibers. Light from the lamp is fed to a ring-shaped configuration of ports, with each port having one or more flexible macroscopic fibers connected thereto.Type: GrantFiled: January 31, 1997Date of Patent: June 8, 1999Assignee: Remote Source Lighting International Inc.Inventors: Andrew P. Riser, Ronald F. Mathis

The combination of the several elements of the inventive system results in a very efficient transfer of the energy of the light source to the light guides. Light from the lamp is fed to four or more ports, with each port having one or more flexible macroscopic light guides connected thereto.Type: GrantFiled: January 31, 1997Date of Patent: January 19, 1999Assignee: Remote Source Lighting International, Inc.Inventors: Andrew P.

Patent number: 5832151Abstract: An optical pipe illumination system is provided for coupling light from an illumination source to a number of output "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 illumination system employs an illumination reflector which has been customized to maximize the efficiency of light transmission between the illumination source, such as an arc lamp, and the cores of the output pipes. A method of fabricating the customized illumination reflector includes mapping the radiation patterns of the particular illumination source to be utilized, creating a database of those radiation patterns, and utilizing the database to generate an optimal illumination reflector configuration. The computer-generated reflector will virtually always be a non-conic section, because the illumination source is not ideal.Type: GrantFiled: November 1, 1996Date of Patent: November 3, 1998Assignee: Remote Source Lighting International, IncInventors: Andrew P. Riser, Richard E. Albrecht, David H. Liu, Nguyen V. To

Patent number: 5751870Abstract: 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.Type: GrantFiled: September 23, 1996Date of Patent: May 12, 1998Assignee: Remote Source Lighting International, Inc.Inventors: John F. Forkner, Andrew P. Riser, Ronald F. Rykowski, Stephen S. Wilson
