Abstract

A wall or ceiling mountable lighting device comprises a self-contained single or multiple LED light source for emitting warm yellow-white light corresponding to halogen or incandescent light and a control circuit controlled by a remote control unit to energize and deenergize the light source and control light intensity. A rechargeable battery power source mounted on the lighting device is connectable to apparatus for charging the battery without removing the battery from the device. The apparatus includes an elongated probe assembly releasably connectable to the lighting device to perform the recharging process. The lighting device is particularly adapted for ease of placement of a light source for decorative purposes and/or illuminating artifacts in locations which would require substantial structural modifications to install conventional lighting.

Claims

1. A electronic charging system, the system comprising, comprising:

a charging apparatus;

a battery unit;

wherein the battery unit comprises a connection apparatus connecting the battery unit to the charging apparatus when charging the battery unit;

wherein the charging apparatus comprises a head member selectively engaged with the battery unit electrically connecting the battery unit to the battery charging apparatus during charging of the battery unit and disconnecting the battery unit from the battery charging apparatus when not charging the battery unit;

wherein the battery unit comprises a unit housing, the unit housing comprising spaced apart curved fingers which selectively receive the head member of the charging apparatus and bias electrical contacts of the head member of the charging apparatus into engagement with electrical contacts on the battery unit electrically connecting the battery unit to the battery charging apparatus during charging of the battery unit;

wherein the charging apparatus comprises a pole or rod coupled to the head member of the charging apparatus; and

a power control circuit coupled to the battery unit, the power control circuit configured to provide electrical current from the battery unit to an electrical load.

2. The charging system of claim 1, wherein the power control circuit provides electrical current from the battery unit to an electrical load using pulse width modulation.

3. The charging system of claim 1, further comprising a selectable number of additional battery units selectively connected in series with the battery unit to extend power output from the power control circuit.

4. The charging system of claim 1, further comprising a selectable number of additional battery units selectively connected in parallel with the battery unit to extend the life of power output by the power control circuit.

5. The charging system of claim 4, further comprising a microprocessor controlled circuit coupled to the battery unit, wherein the microprocessor controlled circuit allows only a single battery unit at a time to be used for supplying current to the electrical load.

6. The charging system of claim 4, further comprising a microprocessor controlled circuit coupled to the battery unit, wherein the microprocessor controlled circuit allows only a single battery unit to be charged at a time.

7. The charging system of claim 1, further comprising a photovoltaic power source coupled to the battery unit to charge the battery unit.

8. The charging system of claim 1, wherein the pole or rod comprises a breakaway coupling that breaks away, while charging, when the pole or rod is inadvertently substantially deflected.

9. The charging system of claim 1, wherein the pole or rod is detachably coupled to the head member such that during charging of the battery unit, the pole or rod can be removed.

10. The charging system of claim 9, wherein the pole or rod is detachably coupled to the head member using a magnet.

11. The electrical charging system of claim 1, wherein the pole or rod is so dimensioned as to permit the battery charging contacts on the head member to engage with the battery charging contacts on the rechargeable battery unit when the battery unit is located beyond the grasp of a user.

12. A method of charging a battery unit, wherein the battery unit comprises connection apparatus connecting the battery unit to a charging apparatus when charging the battery unit, wherein the charging apparatus comprises a head member selectively engaged with the battery unit electrically connecting the battery unit to the battery charging apparatus during charging of the battery unit and disconnecting the battery unit from the battery charging apparatus when not charging the battery unit, and wherein the battery unit comprises a unit housing, which comprises spaced apart curved fingers which selectively receive the head member and bias electrical contacts of the head member into engagement with electrical contacts on the battery unit electrically connecting the battery unit to the battery charging apparatus during charging of the battery unit and wherein:

the charging apparatus comprises a pole or rod coupled to the head member of the charging apparatus, the method comprising;

using the pole coupled to the head member of the charging apparatus, extending the head member to the spaced part curved fingers which selectively receive the head member and bias electrical contacts of the head member into engagement with electrical contacts on the battery unit electrically connecting the battery unit to the battery charging apparatus during charging of the battery;

selectively engaging the head member with the spaced apart curved fingers, wherein the spaced apart curved fingers are laterally and upwardly extending arcuate fingers, such that the spaced apart curved fingers support the head member and bias the electrical contacts of the head member into engagement with the electrical contacts on the battery unit during charging of the battery unit; and

applying electrical power to the head member causing the battery unit to be charged.

13. The method of claim 12, further comprising disconnecting the pole or rod from the head member during charging of the battery unit.

14. The method of claim 13, wherein disconnecting the pole or rod from the head member during charging of the battery unit comprises disconnecting a magnetic cooperation between the pole or rod and the head member, such that disconnection is accomplished when the connection between the pole or rod and the head member is beyond the grasp of the user.

15. The method of claim 12, further comprising selectively coupling a number of additional battery units in series with the battery unit to extend power output from the power control circuit.

16. The method of claim 12, further comprising selectively coupling a number of additional battery units in parallel with the battery unit to extend the life of power output by the power control circuit.

17. The method of claim 12, wherein the battery unit is selectively coupled in parallel with a number of additional battery units, the method further comprising using charging only a single battery unit a time.

18. The method of claim 17, wherein charging only a single battery unit a time comprises using a microprocessor controlled circuit coupled to the battery unit, wherein the microprocessor controlled circuit allows only a single battery unit at a time to be charged.

19. The method of claim 17, wherein charging only a single battery unit a time comprises using dip switches coupled to the battery unit, wherein the dip switches allow only a single battery unit at a time to be charged.

20. A electronic charging system, the system comprising, comprising:

a charging apparatus;

a battery unit;

wherein the battery unit comprises a connection apparatus connecting the battery unit to the charging apparatus when charging the battery unit;

wherein the charging apparatus comprises a head member selectively engaged with the battery unit electrically connecting the battery unit to the battery charging apparatus during charging of the battery unit and disconnecting the battery unit from the battery charging apparatus when not charging the battery unit;
