Abstract
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.
