ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to lighting assemblies for machine tools, and more particularly to equipment work light rings.
2. Description of the Related Art
Anyone using machine tool equipment (e.g., horizontal or vertical milling machines, lathes, drill presses, etc.) Knows that one of the most bothersome problems in using the equipment is adequate lighting in the working area of the machine to properly operate the equipment and monitor the process. Most industrial equipment of this type does not have acceptable/usable lighting on the equipment because no conventional work light apparatus or fixture is practical to the task. It is left to the operator to “jury-rig” or find “something” to adequately light the work area environment.
Magnetic or clamp-on lamp assemblies are most often used. These “solutions” all suffer from inadequacies because they are hot, they are high-voltage, they consume large amounts of energy, they are bulky (their housings actually interfere and obstruct the very area needing illumination), they are either fragile or “burn-out” frequently which is expensive, time consuming and inconvenient, they must constantly be re-positioned to light the changing work areas of the machine, they must constantly be re-positioned to different angles, and the like.
Therefore, a need exists for a convenient, inexpensive apparatus to provide even, unobstructive, auxiliary light on machine tools in their work areas.
The related art is represented by the following references of interest.

SUMMARY OF THE INVENTION
The present invention is an equipment work light ring. The equipment work light ring includes a light ring and a holding ring. The light ring includes an upper side and a lower side. The upper and lower sides of the light ring each include inner and outer diameters. The distance from the inner and outer diameters may be dimensioned according to the desires of the user. For example, the outer diameter of the light ring may be four inches, six inches, or the like. An inner side of the light ring integrally interconnects the inner diameters of the upper and lower sides of the light ring. The inner side of the light ring includes a plurality of attaching elements longitudinally extending therefrom. These attaching elements are configured to securely engage and cooperate with channels included within an outer side of the holding ring. An outer side of the light ring integrally interconnects the outer diameters of the upper and lower sides of the light ring.
The inner and outer sides of the upper side of the light ring defines therein a circular channel. At a lower portion of the channel are a plurality of angled slots, such as fifteen degrees, twenty degrees, or the like, that are each configured for positioning therein a light emitting diode (LED). The lower side of the light ring includes a plurality of apertures defined therein for allowing light from LEDs to pass therethrough.
The holding ring magnetically attaches to a housing of a machine tool, such as a milling machine, a lathe, a drill press, or any other machine having a moving/rotating spindle perpendicular to the work. The holding ring is a generally circular element made of durable, rigid material, such as metal, plastic, or the like. The holding ring includes an upper side and a lower side. The upper side includes at least one magnetic element contained therein.
The at least one magnetic element may be a plurality of magnetic elements, such as magnetic disks or the like, distributed about and embedded within the upper side of the holding ring. Alternatively, the at least one magnetic element may by one magnetic ring embedded within the upper side of the holding ring. The upper side of the holding ring may be configured with pockets or a ring channel to contain embed
