Abstract

A solar powered ground lights is typically mounted in a walkway, pathway, pool deck, roadway, park pathway, either in cement, wood, synthetic materials, or otherwise, and are ideally suited for use in walls, ceilings, and pool or dock areas because they are readily mounted from the top, requiring only a cylindrical depression and possibly three screws for mounting and require no external wiring. The solar powered ground lights are also low voltage and safe. Illumination of the Solar powered ground lights is provided by a Solar Powered system utilizing Light Emitting Diodes (LEDs), or an electro-illuminescent Lighting system backed up with a solar powered circuit for the rechargeable battery. This provides for an illumination system capable if providing ease if view for pedestrians as well as illuminating roadways. The system may be fully IP68 waterproof rated.

Claims8

Dependent claims

A solar powered ground light further comprising:

a base housing having an upwardly disposed groove;
a lens, having a lower rim for being received in the groove of the base housing to sealably and removably attach the lens to the base housing;
top mounting ring having a central opening for engaging the lens and for attachment to the base housing;
an LED mounted underneath the lens;
a solar panel mounted underneath the LED;
a battery carried within the base housing and operably connected to the LED for powering the LED and operably connected to the solar panel for charging the battery, the base housing and lens to form a waterproof envelope;
a compressible o-ring located within the upwardly disposed groove of the base housing and the lower rim of the lens;
and
a transmitter and receiver operably connected to the battery and operably connected to the at least one light source contained within the waterproof envelope to control the at least one light source contained within the waterproof envelope and to communicate with another solar powered illuminated ground light.
