Folded solar module

Decorative solar powered walkway light

A solar powered lamp configured to function more efficiently at elevated temperatures. The solar powered lamp comprises an electrical storage device disposed in heat transfer proximity to a solar cell array. The electrical storage device is adapted to increase its acceptance of charge, provided by the solar cell array, at elevated temperatures. The solar powered lamp is also configured to permit flow of air through the lamp and to be assembled and disassembled with ease.

Decorative solar powered extension lighting fixture

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.

Solar powered light

A self-contained solar powered marking light. The marking light may be utilized to delineate certain predetermined boundaries without effectively illuminating the areas. The marking light automatically illuminates when output power from the photovoltaic cells contained therein fall below a predetermined level and automatically extinguishes when the voltage from the photovoltaic cells reaches a predetermined level. The marking light includes a lens which is closely coupled to a source of light and which includes a textured surface for diffusing the light to cause the lens to appear to glow when the source of light is illuminated. An electrical circuit is coupled between the photovoltaic cells and a battery and includes the source of light and switching means for automatically illuminating the light dependent upon the relative relationship between the voltage of the photovoltaic cells and the battery voltage.

Solar powered light with motion sensor

A solar powered lamp utilizing cold cathode fluoresecent illumination and means for facilitating same. The solar powered lamp is powered through the utilization of photovoltaic cells which charge a battery for providing power to a cold cathode fluorescent bulb in the absence of sunlight. The cold cathode fluorescent bulb provides increased illumination and a longer lamp life. The solar powered lamp comprises circuitry for converting the low power provided by the battery into an alternating current voltage sufficient to operate the cold cathode fluorescent bulb in order to facilitate a longer lamp life and provide increased illumination. In a preferred embodiment, a lens configured with vertically disposed ribs about its inner surface is disposed about the cold cathode fluorescent lamp, which is vertically disposed within the lamp, to further enhance illumination.

Marking light

A self-contained photovoltaic powered light which is a stand alone unit. The solar cells which power the light are assembled and maintained within the top, or upper, portion of the self-contained unit. The solar cells are encapsulated within a resiliently deformable material to provide for contraction and expansion of the solar cells while at the same time providing protection from the elements for the assembly. A component tray assembly is rotationally secured to the upper portion of the lamp and a lens with decorative disks are rotationally secured to the component tray assembly.

Solar powered walkway light

A lens for use in a stand alone lamp utilizing low wattage light bulbs. The lamp is powered through the utilization of photovoltaic cells which charge a battery which then provides power to the bulb in the absence of the sun. The lens is constructed of a hollow body having horizontally disposed ribs formed on the exterior surface thereof with a clear, unobstructed lower portion closing the bottom of the lens.
