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.

Claims8

Dependent claims

A lighting device in combination with a battery-charging apparatus for providing one of decorative illumination, or illumination of a particular subject with aesthetically pleasing light, the combination comprising:

a housing supporting at least one light emitting diode light source and a lens that focuses light emitted by the light source;
a support coupled to the housing that adjusts the direction of a light beam emitted by the light source;
and
a base which supports the housing, a control circuit, and a power source, wherein:
the control circuit controls at least one of the intensity of light emitted by the light source or the direction of the light beam generated by the light source;
and
the power source is electrically connected to the control circuit, and provides power controlling at least one of energization of the light source or direction of the light beam emitted by the light source, and comprises a chargeable battery unit, wherein,
the battery unit comprises connection apparatus connecting the battery unit to a charging apparatus when the battery unit is located beyond the grasp of a user and 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 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 and wherein:
the charging apparatus comprises a telescopic or folding elongated pole or rod coupled to the head member of the charging apparatus.

A method of charging a battery unit of a lighting apparatus when the battery unit is located beyond the grasp of a user, 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 telescopic pole coupled to the head member of the charging apparatus, the method comprising:
using the telescopic pole coupled to the head member of the charging apparatus, extending the head member to the spaced part curved fingers;
selectively engaging the head member with the spaced apart curved fingers, wherein the spaced apart curved fingers are laterally and upwardly extending arcuate 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, wherein the battery unit is included in the lighting apparatus and wherein the lighting apparatus and the battery unit are located beyond the grasp of the user, 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.
