  • Self-contained solar powered light
    Patent number: 5211470
    Abstract: 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.
