Abstract
A solar powered light adapted to be mounted under the eaves of a building, a wall or the like for use in security applications. In a preferred embodiment of the present invention, the solar powered light comprises an adjustable configuration having a lamp with an infrared detector or sensor rotatably mounted thereto and a photovoltaic or solar cell array rotatably disposed at a remote end of an extension arm movably attached to the lamp. Such a flexible arrangement allows the photovoltaic array to be positioned to receive direct sunlight. The sensor activates the solar powered light upon sensing infrared to illuminate the surrounding areas when a presence is sensed and turn it off when a presence is no longer sensed. In accordance with a second embodiment, the solar powered light does not include an infrared detector and provides continuous illumination for a given period of time. In accordance with a third embodiment, the solar powered light does not include an infrared detector, but includes a battery having a higher capacity configured to provide illumination for extended periods of time. In accordance with a fourth embodiment, the solar powered light is configured to be used directly with a user's battery. The solar powered light utilizes a compact fluorescent bulb and circuitry for providing longer lamp life, instantaneous illumination and eliminating flickering during start up.
