Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

WHAT IS CLAIMED IS:
1. A solar powered lamp, comprising:
a solar cell array receiving sunlight and generating charge;
an electrical storage device disposed in heat transfer proximity to said solar cell
array, said electrical storage device being
electrically connected to said solar cell
array to accept charge from said solar cell
array and apply said charge to illuminate an
electrical light source connected to said
electrical storage device, said electrical
storage device accepting substantially all the charge generated by said solar cell array at a temperature greater than 25*C.

2. A solar powered lamp as defined in Claim 1, wherein said electrical storage device accepts at least 75% of the charge transferred from said solar cell array at a temperature greater than said 35 *C.

3. A solar powered lamp as defined in Claim 1, wherein said electrical storage device illuminates said light source when said solar cell array is not producing charge.

4. A solar powered lamp as defined in Claim 1, wherein said electrical storage device is spaced from said solar cell array by a predetermined amount, said predetermined amount defining a path to allow flow of air between said electrical storage aevice and said solar cell array.

5. A solar powered lamp as defined in Claim 4, additionally comprising:
an upper portion, said solar cell array
being disposed within said upper portion;
a component tray having a projecting
portion, said component tray arranged below
said upper portion, said electrical storage
device being disposed in said projecting
portion, said projecting portion extending
away from said solar cell array.

6. A solar powered lamp as defined in Claim 5, wherein said projecting portion comprises openings on a lower surface of said projecting portion, said openings allowing air flow into said projecting portion.

7. A solar powered lamp as defined in Claim 3, further comprising:
a lens disposed about said light source, said lens having a plurality of openings which allow air to flow through said lens.

8. A solar powered lamp as defined in Claim 7, wherein said openings are formed in a lower surface of said lens to allow air to flow in an upward direction within the lamp.

. A solar powered lamp as defined in Claim 7, wherein said lens is formed as an integral unit.

C. A solar powered lamp as defined in Claim 9, wherein said lens is molded from a synthetic polymeric material .

24
ii. A solar powered lamp as defined in Claim 5, wherein said upper portion has intersecting walls defining a chamber therein for allowing air to exit from said chamber.

12. A solar powered lamp as defined in Claim 5, wherein said component tray comprises four intersecting walls, at least one of said walls having a portion thereof cut away to allow air to enter and exit
therethrough.

13. A solar powered lamp as defined in Claim 12, wherein at least one of said walls has an inwardly and upwardly directed member extending from an inner surface thereof, said member being disposed proximate said opening to prevent moisture from entering said component tray.

14. A solar powered lamp as defined in Claim 5, wherein said upper portion has a top lens mounted thereon, said top lens having at least one locking finger which extends through at least one corresponding opening provided in said upper portion.

15. A solar powered lamp as defined in Claim 14, wherein said locking finger terminates in a lip portion, said lip portion when inserted through said opening, abutting the lower periphery of said upper portion to retain said top lens in position.

16. A solar powered lamp as defined in Claim 14, wherein said top lens is formed from an optically clear material.

17. A solar powered lamp as defined in Claim 9, wherein said lens comprises at least one latching member, said latching member being received within a corresponding recess formed along an inner wall of said upper portion and securely retained within said recess.

18. A solar powered lamp as defined in Claim 9, wherein said lens comprises a lip extending along its inner periphery and displaced from an upper extremity thereof, said electrical storage device being disposed within a component tray and said component tray being firmly seated against said lip.

19. A solar powered lamp as defined in Claim 1, wherein said electrical storage device is a high
temperature battery having a recommended charge
acceptance temperature of 35* C.

20. A solar powered lamp as defined in Claim 7 , wherein said lens comprises a protrusion, said
protrusion being threaded bout an external periphery.

21. A solar powered lamp, comprising:
an upper portion having a solar cell
array disposed therein, said solar cell array receiving sunlight and generating charge;
a component tray arranged in heat
transfer proximity to said upper portion, an
electrical storage device disposed within a
projecting portion of said component tray
projecting away from said solar cell array and connected to said solar cell array to accept
charge therefrom; and
a light source connected to said
electrical storage device for acceptance of
charge to illuminate said light source, said
electrical storage device being spaced from
said solar cell array by an amount which
dissipates heat between said electrical and
said solar cell array and maintains an
efficient transfer of charge between said
solar cell array and said" electrical storage
device.
