Abstract
A reading lamp includes a lamp top set having a tubular housing and a support column having a first end and a second end opposite the first end. The support column may include a column wall defining a hollow interior of the support column. A swiveling joint assembly may be positioned between and join the tubular housing and the first end of the support column, such that the swiveling joint assembly enables one or more of polyaxial and rotational movement of the tubular housing relative to the support column or the swiveling joint assembly.
Claims19
A reading lamp, comprising:
- a lamp top set including a tubular housing;
- a support column having a first end, a second end opposite the first end, the support column including a column wall defining a hollow interior of the support column;
- and
- a swiveling joint assembly positioned between and joining the tubular housing and the first end of the support column, wherein the swiveling joint assembly further comprises:
- a tubular housing adapter having a first tubular housing adapter end non-rotatably coupled to an end of the tubular housing and a second tubular housing adapter end opposite the first tubular housing adapter end;
- an adapter pipe rotatably coupled to the second tubular housing adapter end;
- a rotating head portion provided on the second tubular housing adapter end, wherein a swivel limiting slot is formed on the rotating head portion;
- an adapter receiving collar coupled to the rotating head portion and positioned inside the adapter pipe, wherein an adapter receiving collar pin hole formed in the adapter receiving collar and an adapter pipe pin hole formed in the adapter pipe are each in alignment with the swivel limiting slot;
- and
- a swivel limiting pin inserted through each of the adapter receiving collar pin hole, the adapter pipe pin hole, and the swivel limiting slot,
- wherein the adapter, the adapter receiving collar, the adapter pipe, and the swivel limiting pin together define a first rotational joint through which the lamp top portion rotates about a first axis, and the swiveling joint assembly enables one or more of polyaxial and rotational movement of the tubular housing relative to the support column or the swiveling joint assembly.

A reading lamp for connection to an external power supply, comprising:
- a lamp top portion including a tubular housing non-rotatably coupled to a tubular housing adapter;
- a support column having a support column first end non-rotatably coupled to a support column adapter and a support column second end opposite the first end, the support column including a column wall defining a hollow interior of the support column;
- an adapter pipe rotatably coupled to each of the tubular housing adapter and the support column adapter, wherein the tubular housing adapter and the adapter pipe define a first rotational joint through which the lamp top portion rotates about a first rotational axis, and wherein the support column adapter and the adapter pipe define a second rotational joint through which the lamp top portion rotates about a second rotational axis that is transverse to a third axis of the support column;
- and
- a lamp power interface set positioned in the hollow interior of the support column in a spaced apart relationship from the second end of the support column, wherein a length between a lower surface of the lamp power interface set and the support column second end is equal to a length of a retention portion of the support column, and the retention portion and lower surface of the power interface set are together dimensioned for receiving and connecting to an external power source.

A method for powering and operating a reading lamp, comprising:
- inserting a lower end of a support column of the reading lamp into a retaining structure, wherein the reading lamp comprises:
- a lamp top portion including a tubular housing non-rotatably coupled to a tubular housing adapter;
- a support column having a support column first end non-rotatably coupled to a support column adapter, and a support column second end opposite the support column first end, the support column including a column wall defining a hollow interior of the support column;
- and
- an adapter pipe rotatably coupled to each of the tubular housing adapter and the support column adapter, wherein the tubular housing adapter and the adapter pipe define a first rotational joint through which the lamp top portion rotates about a first rotational axis, and wherein the support column adapter and the adapter pipe define a second rotational joint through which the lamp top portion rotates about a second rotational axis that is transverse to a third axis of the support column, and
- contacting an electrically contactable projection provided on a lower surface of a lamp power interface set positioned within the hollow interior of the support column in a spaced apart relationship from the lower end of the support column with an electrically contactable connection positioned within the retaining structure.
