Abstract

PROBLEM TO BE SOLVED: To substitute a fluorescent tube with an LED lighting device, with the use of a fluorescent-tube lighting device existing in the ceiling.SOLUTION: In a method of replacement, that is, a mounting method of the flat-type LED lighting device 4, two hanging rods 5 as jigs having similar-shape jointing pins at either end of the fluorescent tube are insertion-fixed to either-end jointing part from which the pin-insertion-fixed fluorescent tube is taken off, while, on the other hand, a plurality of hooking brackets 6 are arranged in two rows at a given interval at the LED lighting device 4, with the pedestal and a long side aligned, and a short side of the device slanted against the ceiling face while it is inserted into a space inside the pedestal, and the device is hooked to the two hanging rods 5 to a top face through the plurality of hooking brackets 6, so that an illumination face of the device is to be installed on the pedestal of the fluorescent tube nearly horizontally to a ceiling face, in a method of replacement of the fluorescent-tube lighting device with the LED lighting device 4.

Description

The present invention relates to a method for installing an LED lighting device on an existing fluorescent tube device installed on a ceiling.

With the development of energy-saving long-lasting LED lighting devices, the replacement of existing fluorescent tube devices has progressed, and LED lighting devices that are installed using existing fluorescent tube devices as they are are required.

Japanese Patent Application No. 2004-75541

Through a jig replaced with the fluorescent tube of the existing fluorescent tube lighting device mounted on the ceiling,
This is the development of an LED lighting device to be installed on the existing fluorescent tube mount.

The LED illuminating device of the present invention is an illuminating device in which a fluorescent tube of an existing fluorescent tube illuminating device is replaced with a hanging round bar and a plurality of hanging tools on the upper surface of the flat LED lighting device are hung on the hanging round bar.

The hanging round bar of the present invention is a hanging round bar having two joining pins similar to the joining pins of the fluorescent tube at both ends.

The LED lighting device of the present invention is installed using the existing fluorescent tube mount on the ceiling, and is a quick and easy LED lighting device that does not require a new foundation work.

A method for installing an LED lighting device using an existing fluorescent tube light stand on the ceiling of the present invention will be described with reference to FIGS. In the internal space of the existing fluorescent tube mount 2 that is recessed above the ceiling surface 1 shown in FIG. 1, two sockets at both ends of the two fluorescent tubes are connected to the socket joint 3 that serves both as electrical connection and fixing at both ends. In other words, two fluorescent tubes are similarly attached to the fluorescent tube mount installed below the ceiling surface.

The recent development of LED lighting devices has been replaced with the fluorescent tube of this fluorescent tube device,
It is required to install a flat LED lighting device. This replacement method, that is, the method of attaching the flat LED lighting device 4 shown in FIG. 2, is to remove the fluorescent lamp pin-fitted and fixed to the joints at both ends, Two hanging round bars 5 indicated by dotted lines, which are jigs having joining pins at both ends, are fitted and fixed. On the other hand, a plurality of, for example, inverted L-shaped hooks 6 that are hooked on the hanging round bars are predetermined on the upper surface, that is, the non-illuminated surface. Aligned with the hanging round bar at intervals, arranged in two rows, align the LED lighting device to which the power line newly led from the ceiling is connected and the length of the gantry, and the short side of the lighting device with respect to the ceiling surface While tilting and inserting it into the gantry interior space,
The illumination surface of the illuminating device is installed in the interior of the fluorescent tube base with substantially no gap and substantially horizontally on the ceiling surface.

In the same way, the fluorescent lamp stand installed below the ceiling surface is flat plate-shaped LE.
D Install lighting equipment. In the case of a lighting device with three or more parallel fluorescent tubes, any two or more are replaced with hanging round bars, and an LED lighting device having a plurality of inverted L-shaped hooks on the top surface is installed as described above. In addition, instead of a hanging round bar, horizontal pieces of L-shaped material are joined by joining discs with two fitting pins similar to both ends of the fluorescent tube to both end surfaces of the L-shaped material of approximately the length of the fluorescent tube. A hanging rod that receives the hanging fixture of the LED lighting device is also good.

It is a fragmentary perspective schematic diagram of the existing fluorescent tube stand. It is a perspective view of a hanging round bar shown with a LED lighting device of the present invention and a dotted line.
