Filed:

Nov 13, 2000

Appl. No.:

09/711805

Inventors:

Frederick G. Hewitt - Eagan MN
Steven J. Orfield - Minneapolis MN

Assignee:

Orfield Laboratories, Incorporated - Minneapolis MN

International Classification:

G01N 2100

US Classification:

3562371

Abstract:

A method of establishing a lighting system and viewing environment for conduct of visual task is provided. The method generally includes steps of providing a visual performance lab, conducting a visual performance study, and constructing an industrial viewing station based upon the results of the visual performance study. The invention also concerns provision of a preferred visual performance lab and development of preferred industrial viewing stations.

Filed:

Jan 6, 2003

Appl. No.:

10/338130

Inventors:

Steven J. Orfield - Minneapolis MN
Michael R. Role - Roseville MN

Assignee:

Orfield Laboratories, Inc. - Minneapolis MN

International Classification:

F21V 700

US Classification:

362346, 362147, 362302

Abstract:

A light fixture is described. The light fixture includes a socket housing and a reflector housing. The socket housing includes a socket for receipt of a lamp, and a reflector housing mounting surface. The reflector housing includes a direct reflector for providing direct light onto a target lighting area and an indirect reflector for providing indirect light onto the target lighting area. The direct reflector includes a direct reflector first end, a direct reflector second end, and a direct reflector body extended between the first end and the second end. The direct reflector body extends sufficiently far to provide a cut off angle between a lamp provided in the socket and the direct reflector second end of less than about 50Â. The indirect reflector extends from the direct reflector around a circumference of the direct reflector in an amount sufficient to shield a lamp provided in the socket. A facility having a plurality of ceiling mounted light fixtures, and a reflector housing are described.

Abstract:

A smart, adaptive control system that monitors and influences physical conditions of an architectural setting. The architectural setting in which the system is deployed typically includes a plurality of private spaces and at least one community space. The individual private spaces, and the community spaces, may include an environmental control device that affects one or more physical conditions of the individual private space. Each private space may also include an environmental sensor that measures a particular physical condition of the private space. The private spaces may also include one or more occupant sensors, which measure either behavioral or physiological parameters of an occupant. The environmental control devices, environmental sensors, and occupant sensors are in communication with a computer. The computer is also in communication with a database, which houses a data set that describes how to best modify the physical conditions of the architectural setting.
