Abstract

Solar powered and/or augmented lighting systems embodied within conventional hollow light pole configuration incorporating a solar power lamp cell. A plurality of solar cells are disposed in an array about an upstanding light pole of conventional design of the type having a hollow interior and laterally extending lighting elements. The lighting element itself is provided in a configuration incorporating a solar cell atop a storage battery atop a light source, such as a bulb, operable from said light power system. The lighting cell is selectively powered by either a storage battery system operable in conjunction with the solar panel array and/or the solar power network incorporated therein. A network of electrical storage cells are disposed within the hollow configuration of the light pole and supported upon an elevator system for facilitating access thereto. In this manner, the overall consumption of energy from conventional power lines may be reduced and/or eliminated. The commercial lines may remain connected to said light poles for augmented power during periods of low solar energization and for purposes of original solar collector orientation.

Claims

1. An improved lighting system illuminating an area in times of darkness of the type having an upstanding light pole of generally hollow interior construction extending from an underlying base secured upon the ground for supporting a plurality of light emitting elements thereabove wherein the improvement comprises:

a remotely disposed, moveable solar collector panel disposed about said light pole;

a tracking mechanism for orientating said collector panels relative to the sun;

a plurality of storage batteries secured to said lighting pole;

means coupling said storage batteries to said collector panel or the energization of said batteries therefrom;

means interconnecting said storage batteries to said light emitting elements for the energization thereof; and

control means secured to said light pole for interconnecting said collector panel to said batteries and said batteries to said light emitting element in response to the amount of sunlight falling on said collector panels; and

a conveyor elevator within said light pole housing said storage batteries therein, said light pole including an entry door for providing access to said storage batteries upon said conveyor elevator.

2. The apparatus as set forth in claim 1 wherein said collector panels are foldably configured for confinement adjacent the longitudinal periphery of the light pole during the evening hours.

3. The apparatus as set forth in claim 2 and including an electro-mechanical network for deploying said collector panels foldably confined about said light pole during daylight hours.

4. The apparatus as set forth in claim 3 and including tracking means housing with the generally hollow interior of said light pole and constructed for causing said deployed collector panels to track the sun for maximizing solar collection.

7. A method of lighting a ground area in times of darkness with solar energy in place of conventional power lines and utilizing storage batteries and upstanding light pole comprising the steps of:

providing a solar collector upon the light pole with tracking means for orienting the collector relative to the sun;

remotely disposing the solar collector panel about an upper portion light pole;

tracking the sun with the solar collector panel;

securing the storage batteries within a conveyor elevator within the light pole and having the storage batteries thereon in a configuration facilitating elevator access thereto;

energizing the storage batteries with the solar collector panel; and

energizing a light producing element received upon the light pole.

5. The method as set forth in claim 7 and including means coupling the light pole to conventional power lines for supplying power to the batteries in times of limited solar energy.

6. The method as set forth in claim 7 wherein the step of remotely disposing the solar collector panels about the light pole includes the step of foldably confining said panels adjacent the longitudinal periphery of the light pole during the evening hours.
