ABSTRACT:
TECHNICAL FIELD
The present invention resides generally in the art of lighting fixtures and, more particularly, in the art of lamp shade holders. More specifically, the present invention is directed towards a shade holder for non-incandescent ballasted lamps, such as fluorescent lamps.
BACKGROUND ART
It is well known that high intensity discharge light sources and fluorescent light sources are desirable over incandescent light sources in many lighting applications for a variety of reasons. As compared to incandescent light sources, these light sources tend to provide superior optical control characteristics, power efficiency and longevity, and these factors, in turn, make such light sources desirable for reasons of economics. Indeed, increased use of these light sources for residential lighting can help reduce the relative amount of power required to properly light homes and apartments. The same economics can be realized in the commercial arena when used in hotels and the like. In light of this knowledge, it is desirable to provide a shade holder for such light sources. In addition, it is desirable to provide a shade holder that can be used to convert the common residential lamp using incandescent bulbs into a lamp capable of utilizing separately ballasted high intensity discharge, compact fluorescent and other non-incandescent bulbs. Moreover, it is desirable to hard wire these ballasts in the lamp so that replacing burned out fluorescent bulbs or high intensity discharge bulbs does not require replacement of the ballast.
DISCLOSURE OF INVENTION
In light of the foregoing, it is a first aspect of the present invention to provide a shade holder to be used in conjunction with separately ballasted high intensity discharge, compact fluorescent and other non-incandescent bulbs.
Another aspect of the present invention is to provide a shade holder having a saddle and harp design so as to be easily mountable onto a common table or floor lamp.
Still a further aspect of the present invention is to provide a shade holder, as above, providing the requisite mounting space needed for the ballasts associated with high intensity discharge, compact fluorescent and other non-incandescent bulbs.
Yet another aspect of the present invention is to provide a shade holder, as above, allowing for the easy installment and/or replacement of the ballasts and bulbs associated herewith.
The foregoing and other aspects of the invention which will become apparent as the detailed description proceed are achieved by a shade holder for ballasted lamps, comprising: a saddle having a base with spacer members extending from opposite ends thereof; and a harp received by said saddle, said harp being generally oval in shape.
Other aspects of the invention that will become apparent herein are achieved by a lamp assembly, comprising: a saddle; a ballast nestingly received by said saddle; a lamp received by said ballast; and a harp received by said saddle, said harp forming a loop over said ballast and lamp.
