Outdoor solar light with multi-panel solar array
View Patent ↗A solar powered lighting fixture having a multi-paneled solar array that maximizes the generation of solar energy during the course of a day. The outdoor lighting fixture of the present invention includes a multi-paneled solar array housing positioned on an extension rod that includes a plurality of solar panels arranged in a slanted configuration about the periphery of the housing unit. The housing unit is positioned on the extension rod so as to be elevated above the ground but below the actual light fixture. Employing a housing unit separate from the light fixture permits a greater variety of shapes to be used for the light fixture. Moreover, it allows the individual solar panels to be positioned at an optimal angle for maximizing exposure to solar radiation. Each of the solar panels is independent of the others, charging the battery separately so as not interfere with the other solar panels.
1. A solar powered outdoor light fixture comprising:
a light emitting diode (LED) module;
a multi-panel solar array housing having an upper portion and a lower portion, the housing comprising:
an upper receiver mount extending from the upper portion of the housing;
a lower receiver mount extending from the lower portion of the housing;
a plurality of solar-panel slots evenly distributed about the upper portion of the housing; and
a plurality of corner faces, each disposed between a respective adjacent pair of the solar-panel slots;
a rechargeable battery disposed within the multi-panel solar array housing;
a lower extension shaft having upper and lower ends thereof, the lower extension shaft having a ground spike on the lower end thereof,
wherein the upper end of the lower extension shaft extends into the lower receiving mount of the multi-panel solar array housing;
an upper extension shaft, coaxial with the lower extension shaft, disposed between the LED module and the multi-panel solar array housing, the upper extension shaft having upper and lower ends thereof,
wherein the lower end of the upper extension shaft extends into the upper receiving mount of the multi-panel solar array housing;
a plurality of solar panels, each disposed within a respective one of the plurality of solar-panel slots at an oblique angle relative to the upper and lower extension shafts; and
circuitry disposed within the multi-panel solar array configured for receiving electrical power from the solar panels, providing electrical power from the rechargeable battery to the LED module, and recharging the rechargeable battery using electrical power received from any one of the plurality of solar panels independently of others of the plurality of the solar panels.
2. The solar powered outdoor light fixture of claim 1 , further comprising a retainer base attached to the upper end of the upper extension shaft for supporting the LED module.
3. The solar powered outdoor light fixture of claim 2 , further comprising an open-ended light shade supported by the retainer base.
4. The solar powered outdoor light fixture of claim 2 , further comprising a closed-ended light shade supported by the retainer base.
5. The solar powered outdoor light fixture of claim 1 , further comprising a light sensor arranged to sense ambient levels of light, wherein the circuitry is further configured to control the LED module based on the light sensed by the light sensor.
6. The solar powered outdoor light fixture of claim 1 , wherein the upper extension shaft is hollow and the lower extension shaft is solid.
7. The solar powered outdoor light fixture of claim 5 , wherein the lower extension shaft includes a stabilization spike attached thereto, wherein a portion of the stabilization spike extends parallel to the lower extension shaft.
8. The solar powered outdoor light fixture of claim 1 , wherein the light sensor is positioned so as to be isolated from light emitted by the LED module.
