ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to electric lighting apparatus and, more particularly, to a desk lamp which includes the combination of general area lighting and task lighting to direct light onto the desk work area.
BACKGROUND OF THE INVENTION
Electric lighting apparatus in the form of floor lamps, table lamps and desk lamps is well known. Such lamps generally take the form of a general lighting device or alternatively, a task lighting device. In the recent past stand alone floor lamps having a combination of general lighting and task lighting on the same structure has been provided. Typical of such a structure is that disclosed in Applicant's U.S. Pat. No. 5,221,141. However, Applicant is unaware of any lamp structure designed to be placed on a desk top which provides the combination of general area lighting, as well as task lighting for use in and around the general work area of a desk or similar structure.
SUMMARY OF THE INVENTION
A desk lamp having both general area lighting and task lighting which includes a base member with a hollow stem having one end affixed thereto and having a general area lighting means affixed to the other end of said stem. The overall height of the desk lamp is such that an average adult when standing with the lamp disposed upon a desk will not look into the general area lighting means. The stem includes at least one light reflector affixed thereto intermediate the base and the general area lighting means directing light generally downward upon the desk work area.
