The present invention relates to a luminaire elevating device, and more specifically, to provide convenience of maintenance and maintenance for lighting installed in a high ceiling such as an indoor gymnasium, auditorium, a factory, a performance hall, and to adjust the height of the lighting lamp as needed. It relates to a luminaire lifting device.

The present inventors use the cable consisting of a wire and a power supply line through Patent Application No. 10-2004-0060378 "Ceiling installation luminaire elevating device", it is possible to turn on and off the light at the desired position even during the elevating operation of the luminaire. It has been proposed a luminaire lifting device that can prevent the cable from being twisted.

Such a luminaire elevating device meets the technical requirements of transportation and power supply by using a specially proposed cable, but it is required to improve the lighting level. In other words, the inventors of the present application attempted to maintain the horizontal level of the lamp by allowing the ballast box combined with the lamp to be moved up and down by the winding driver using a flat cable having wires installed at both sides and a power supply line installed in the middle. The flat cable alone could not effectively prevent the problem of tilting the lamp by absorbing various variables (errors generated during assembly, minute deviation of cable thickness, etc.).

Accordingly, an object of the present invention is to provide a new type of luminaire lifting device capable of effectively adjusting the horizontal level of a lighting lamp.

In another aspect, the present invention provides a new type of lifting device that can effectively balance the lighting even in the case where two or more lighting is installed in consideration of the characteristics of the lighting is configured using the light lifting device. have.

According to a feature of the present invention for achieving the above object, the present invention comprises a ballast box and a lamp is installed; It is connected to the ballast box by two cables arranged in parallel with each other, an actuator is installed therein includes a winding drive for moving the ballast box up and down by winding or unwinding the two cables at the same time; The ballast box has a balancing plate coupled to each of the two cables on both sides, the central portion is hinged to the ballast box, so that the parallel to the lamp by the balancing plate.

Such a luminaire lifting apparatus according to the present invention further comprises a balancing bar unit which is horizontally coupled to the ballast box and the lighting lights are coupled to both sides; The balancing bar unit has a central portion coupled to the ballast box, a horizontal balancing bar having both sides extending from both sides from the central portion having the same length, and hinged at both sides of the horizontal balancing bar at the same positions, respectively, in a downward direction. Extending to each end having a vertical balancing bar coupled to the lamp at each end, so that the lamp can be maintained horizontal.

In the luminaire lifting apparatus according to the present invention, the horizontal balancing bar and the vertical balancing bar may be hinged by bolts and nuts to fix the angle of the lamps coupled to the ends of the respective vertical balancing bars.

The luminaire lifting device 10 according to the present invention, as shown in Figure 1, by improving the luminaire lifting device consisting of a conventional winding drive unit 60 and the ballast box 20 so that the level of the lamp 90 is automatically made. .

The luminaire elevating device 10 according to the present invention is connected to the ballast box 20, the ballast box 20 and the cable 80, the balancing plate 30 is installed to move the ballast box 20 up and down The winding drive unit 60 is provided. At this time, the basic configuration of the ballast box 20 and the winding drive unit 60 can be applied to the technical configuration of the luminaire lifting device and the conventional luminaire lifting device proposed by the present inventor. Therefore, the detailed description of the technical configuration additionally provided to the ballast box 20 and the winding drive unit 60 in the luminaire lifting device 10 according to the present invention will be omitted.
