Description




FIELD OF THE INVENTION




The present invention is related to a lighting apparatus having a gimbal assembly with at least one ring to hold a lamp. More specifically, the present invention is related to a lighting apparatus having a gimbal assembly with at least one ring having a lamp where the ring can be locked into place.




BACKGROUND OF THE INVENTION




In many situations, lighting is used not only to illuminate an area to bring attention to an area, but to create a lighting effect on an area. To do this, the lamp is carefully chosen to focus on a specific area. This means that when a gimbal assembly is used, the ring or rings must be carefully positioned to achieve the aforementioned results. The gimbal assembly is then left alone until the lamp held by the gimbal assembly simply needs to be changed. When this happens, the ring or rings are jarred and moved from their previously set position. After the lamp is replaced, the ring or rings must be reset. In many instances, where the lamp is in the ceiling, this is not always simple. Also, the persons responsible for changing the lamp may not be qualified to properly refocus the lamp and gimbal assembly. The present invention avoids having to reset the gimbal assembly after the lamp is changed.




SUMMARY OF THE INVENTION




The present invention pertains to a lighting apparatus. The lighting apparatus comprises a mounting structure. The apparatus comprises a gimbal ring assembly for holding a lamp. The gimbal ring assembly has a first axis and a second axis perpendicular with the first axis. The gimbal ring assembly is rotatable about the first axis and about the second axis. The gimbal ring assembly is connected to the mounting structure. The apparatus comprises a locking mechanism for locking the gimbal ring assembly in a fixed position relative to the first axis, to the second axis and the mounting structure.




The present invention pertains to a lighting apparatus. The lighting apparatus comprises a yoke. The apparatus comprises a lamp ring for holding a lamp. The lamp ring is connected to the mounting structure. The apparatus comprises a ring locking mechanism for locking the lamp ring in a fixed position relative to the yoke.




The present invention pertains to a method for lighting. The method comprises the steps of attaching a mounting structure to a ceiling. Then there is the step of orienting an outer ring of a gimbal ring assembly at a first position relative to a second axis of the gimbal ring assembly. Next there is the step of locking the outer ring in place relative to the mounting structure. Then there is the step of orienting an inner ring having a lamp of the gimbal ring assembly at a second position relative to a first axis of the gimbal ring assembly. Next there is the step of locking the inner ring assembly to the outer ring assembly.

The present invention pertains to a method for lighting. The method comprises the steps of attaching a mounting structure


12


to a ceiling. Then there is the step of orienting an outer ring


22


of a gimbal ring assembly


14


at a first position relative to a second axis


18


of the gimbal ring assembly


14


. Next there is the step of locking the outer ring


22


in place relative to the mounting structure


12


. Then there is the step of orienting an inner ring


24


having a lamp


55


of the gimbal ring assembly


14


at a second position relative to a first axis


16


of the gimbal ring assembly


14


. Next there is the step of locking the inner ring


24


assembly to the outer ring


22


assembly.




Preferably, after the locking the inner ring


24


step, there is the step of changing the lamp


55


of the inner ring


24


without the position of the inner ring


24


or outer ring


22


changing.




In the operation of the preferred embodiment, a lighting apparatus


10


is placed in a ceiling. This placement occurs by fixing the mounting structure


12


to the ceiling as is well known in the art. In the mounting structure


12


is a gimbal ring assembly


14


. The gimbal ring assembly


14


is comprised of an outer ring


22


and an inner ring


24


. The gimbal ring assembly can be a standard MR


16


gimbal ring assembly available from Modular International, Inc. of Pittsburgh, Pa. The inner ring


24


holds a lamp. The inner ring


24


is rotatably connected to the outer ring


22


and the inner ring


24


is able to rotate about a first axis


16


of the gimbal ring assembly


14


. The outer ring


22


is rotatably attached to the mounting structure


12


, as is well known in the art, so that the outer ring


22


can rotate about a second axis


18


.




A first locking threaded screw or stud


30


is screwed through a hole in the outer ring


22


and further threaded into a threaded hole


40


in the inner ring


24


. When the first locking threaded screw or stud


30


is tightened, it screws through the hole in the outer ring


22


and screws in to the threaded hole


40


in the inner ring


24


where it fixes the outer ring


22


with the inner ring


24


so the inner ring


24


cannot move or rotate. After the outer ring


22


is placed in a desired position relative to the second axis, the first locking threaded screw or stud


30


is tightened to fix the inner ring


24


in place so the lamp remains focused and fixed in place in a desired direction.




The outer ring


22


is fixed in place after it is rotated to a desired position relative to the second axis


18


by a locking clip


34


first being mounted to the side of the mounting structure


12


through a hole or slot


32


in the mounting structure


12


. A second threaded screw or stud


36


extends through the locking clip


34


and through a locking clip hole


35


so it extends into the interior of the mounting structure


12


.




The second threaded screw or stud


36


is screwed through a hole in the outer ring


22


that is aligned with the locking clip hole


35


until it threads into an inner nut


38


. The inner nut


38


is disposed between the inner ring


24


and the outer ring


22


. When the second threaded screw or stud


36


is tightened into the inner nut


38


, the outer ring


22


becomes held by the threaded stud in place relative to the mounting structure


12


and the second axis


18


.




The locking nut


38


can have a locking head


42


with holes


44


which receive a tool, such as an Allen wrench, to facilitate tightening or loosening of the second threaded screw or stud


36


. Similarly, the inner nut


38


can have an inner head


46


with holes


44


for the same purpose to facilitate tightening or loosening.




The advantage of the present invention is that it allows the inner ring


24


and outer ring


22


to be fixed in place once the lamp is in the desired position. Whenever the lamp burns out or needs to be changed for whatever reason, whether it be a day, a week, a month or a year later, the lamp can be changed without any concern of disturbing the position the lamp is held in by the gimbal ring assembly. This is because the inner ring


24


and outer ring


22


have become fixed in place through the use of the second threaded screw or stud


36


, locking clip


34


, inner nut


38


, first locking threaded screw or stud


30


and threaded hole


40


.




In a similar manner, a yoke


48


which only has a lamp ring


50


can have a locking clip


34


attached to the yoke


48


. The second threaded screw or stud


36


can then be used with an inner nut


38


to hold the lamp ring


50


in place, for the same reason, as described above.




Although the invention has been described in detail in the foregoing embodiments for the purpose of illustration, it is to be understood that such detail is solely for that purpose and that variations can be made therein by those skilled in the art without departing from the spirit and scope of the invention except as it may be described by the following claims.
