Patent number: 5160193Abstract: The apparatus is a modular medical lighting system which includes a ceiling-mounted reading light module, examination light module, ambient light module, and a night light module. The reading light is directed toward a selected reading area on a hospital bed directly below the medical lighting system. The examination light illuminates the entire top surface of the hospital bed. The ambient light directs light to a wall abutting the head of the hospital bed thereby providing reflected light to the vicinity of the hospital bed. The night light directs light to a selected side of the bed so as to light a nurse's medical chart clipboard without disturbing the patient. The modules may be provided separately or in combination.Type: GrantFiled: February 4, 1992Date of Patent: November 3, 1992Assignee: Keene CorporationInventors: William C. Fabbri, Roy Crane

Patent number: 5008790Abstract: A fluorescent light fixture is provided which includes a housing with an inwardly extending L-shaped tab. This inwardly extending L-shaped tab engages a channel in a removable socket assembly. The channel of the socket assembly can be slid into the tab so that the socket assembly, along with the sockets themselves, is in a protected position within the housing. The channel is expanded so as to permit the rotating of the socket assembly thereby bringing the sockets into position to engage fluorescent light bulbs when desired.Type: GrantFiled: March 14, 1989Date of Patent: April 16, 1991Assignee: Genlyte, Inc.Inventor: William C.
