Description




FIELD OF THE INVENTION




The present invention is related to a motorized lamp fixture. More specifically, the present invention is related to a motorized lamp fixture that has a first drive element and a second drive element for moving the lamp in a first dimension and a second dimension, respectively, for positioning the lamp in a desired position.




BACKGROUND OF THE INVENTION




Directed lighting fixtures are found in many locations. These locations include places that are generally inaccessible without a ladder or other equipment that allows the fixture to be reached, for instance, to change the lamp, or reconfigure the direction of the lamp. If the lamp needs to be reconfigured, then the ladder or special equipment must be brought out and the fixture reached and the direction of the lamp changed. Alternatively, when the lamp must be replaced, many times, the direction of the lamp is changed upon its removal, and upon replacement, it must be redirected to shine its light onto a desired area. In many instances, the alignment of the lamp is a very tedious operation, and when standing on a ladder, or using special equipment, is made all that more difficult. Consequently, the redirection or the replacement of the lamp is commonly a very time-consuming exercise.




The present invention allows for the redirection of a lamp, whether the lamp has just been replaced and needs to be repositioned into its desired position, or moved to a new position, by remote control with the use of a motorized system that moves the lamp.




SUMMARY OF THE INVENTION




The present invention pertains to a system for lighting a room having a ceiling. The system comprises at least a first lamp for producing light. The system comprises motorized means adapted to be disposed in the ceiling for positioning the first lamp in a desired position by moving the first lamp, preferably linearly. The motorized means is connected to the lamp.




The present invention pertains to a method for lighting. The method comprises the steps of directing a first motor disposed in a ceiling of a room with a controller. There is the step of positioning a first lamp into a desired position with the first motor by moving the first lamp linearly.

In the operation of the invention, a fixture


48


is attached to a ceiling or wall by well known techniques. The fixture


48


has motorized means


14


for positioning a first lamp


12


in a desired position. The motorized means


14


comprises a drive train


20


that is used to position the lamp in a desired position. The drive train


20


has a first drive element


26


comprising a rubber edged track


50


, in the form of a circular plate, that is positioned in a horizontal plane relative to the fixture


48


and rubber wheels


52


disposed at the corners of the fixture


48


. The rubber wheels


52


are disposed such that there are two rubber wheels


52


at each corner with a space between each rubber wheel at each corner forming a groove. The rubber edged track


50


is positioned within the grooves


36


that are formed by the rubber wheels


52


at each corner. The rubber wheels


52


turn and move, as well as guide, the rubber edged track


50


as the rubber wheels


52


move. The first motor


16


disposed at a corner of the fixture


48


, aligns with and engages the pair of rubber wheels


52


at the same corner it is disposed at. The first motor


16


moves the rubber wheels


52


to which it is attached, causing the rubber edged track


50


to move as it is guided by the rubber wheels


52


at the other corners of the fixture


48


. The movement of the rubber edged track


50


moves the lamp in the first dimension. It should be noted the track and wheels do not have to be rubber, but metal, ceramic or plastic.




Positioned across the center of the rubber edged track


50


is a second drive element


28


of the drive train


20


. The second drive element


28


is linear, includes a linear track that has a variable slope, and also has wheels that are mounted on the lamp adjustment assembly. The lamp adjustment assembly and the wheels that are mounted to it form the lamp attachment means


24


. The movements of the lamp adjustment assembly from the action of the second motor


22


attached to and driving the wheels on it, moves the lamp in a second dimension by moving along the linear track to a desired position on the variable slope so the lamp is caused to aim at a desired location. Mounted on the underside of the track is a socket assembly


54


for holding the lamp, as shown in FIG.


4


. The socket assembly


54


is part of the lamp attachment means


24


. Movement of the rubber track by the first motor


16


moves the lamp along a first plane and movement of the lamp adjustment assembly in the second plane allows the lamp to be positioned in the second dimension, and together with respect to both dimensions the lamp can be placed in a desired position.




Alternatively, but instead of rubber rings and wheels, gears can be used to move the lamp adjustment assembly to any desired position. Power leads extend from the lamp adjustment assembly and are connected to the second assembly to provide electricity to the lamp.




A controller


18


that is disposed remote from the fixture


48


provides a drive signal to the first motor


16


and to the second motor


22


to cause them to move the first drive element


26


and second drive element


28


, respectively, into a desired position so the lamp is moved into a desired position. The controller


18


can have a keyboard in which the coordinates of each respective drive element is inputted, or a joy stick or wheel or mouse, with a switch that determines which drive element is being controlled at a given time, to move the lamp into the desired position. A memory that is part of the controller


18


, can store a desired position that is chosen for the lamp relative to the first drive element


26


and the second drive element


28


. The controller can store the location of the lamp relative to each dimension so it knows where the lamp of a given fixture is at all times. Then, since the controller knows where the lamp is relative to each drive element, it can move the lamp relative to each drive element to a new position.




The controller


18


is connected to each motor through wires, or wireless and uses electromagnetic radiation, such as radio signals or infrared signals to input the drive signals to the motors. The controller


18


has a transmitter


30


which transmits a drive signal, and each motor has a receiver


32


which receives the drive signal and activates the respective motor according to its drive signal. Connected to the controller


18


are additional fixtures


48


with motorized means


14


and motors that are controlled by the controller


18


in the same way as described above in regard to the fixture


48


, as shown in FIG.


5


.
