A light fixture 112 is attached to the lifting unit 40 and the light fixture 112 emits light outwardly from the light fixture 112 when the light fixture 112 is turned on. The light fixture 112 is lifted toward the support panel 12 when the lifting unit 40 is actuated to rotate in the first direction. In this way the light fixture 112 can be lifted to enable an overhead door 114 to travel beneath the light fixture 112 when the overhead door 114 is in an open position. The light fixture 112 is lowered away from the support panel 12 when the lifting unit 40 is actuated to rotate in the second direction. In this way the light fixture 112 can be positioned near a work area 116 thereby enabling the light fixture 112 to illuminate the work area 116 when the light fixture 112 is turned on. Thus, a user 118 with limited vision, such as an elderly user or a user with a visual disability, can enjoy improved vision in the work area 116 to enable the user 118 to perform work in the work area 116.
The light fixture 112 is attached to a distal end 120 of each of the pair of conductors 68 such that the light fixture 112 is suspended beneath the support panel 12. The light fixture 112 is electrically coupled to each of the pair of conductors 68 thereby enabling the light fixture 112 to be in electrical communication with the transformer 76 such that the transformer 76 supplies electrical power to the light fixture 112. Furthermore, the light fixture 112 may be in electrical communication with the control processor 100 via either a control conductor that is coextensive with a respective one of the pair of conductors 68 that is electrically coupled to the light fixture 112 or via electrical communication with the slip ring 78. The light fixture 112 is turned on when the control processor 100 receives the on input and the light fixture 112 is turned off when the control processor 100 receives the off input. The light fixture 112 includes a light emitter 122, such as a fluorescent light bulb, for example, or other type of electronic light emitter, which is disposed on a lower surface 124 of the light fixture 112.
In use, the suspensions 14 are attached to the horizontal support surface 18 to position the light fixture 112 in a desired location. The remote control 98 is employed to lower the light fixture 112 toward the work area 116 and to turn on the light fixture 112 to illuminate the work area 116. In this way the user 118 can enjoy a well illuminated work area 116 while performing work in the work area 116. The remote control 98 is employed to lift the light fixture 112 upwardly toward the horizontal support surface 18 to enable the overhead door 114 to be opened without striking the light fixture 112, for example, or to inhibit the light fixture 112 from impeding any other type of movable object that is located in the work area 116. Furthermore, the light fixture 112 can be turned on while the light fixture 112 is lifted against the support panel 12 or the light fixture 112 can be turned on while the light fixture 112 is lowered from the support panel 12. The remote control 98 includes an intensity adjustment to adjust the intensity of the light fixture 112 between a minimum intensity or a maximum intensity, depending on the user's preference.
