In order to eliminate the problems of an existing opening and closing device for lighting and a lighting device using the same that the supporting force of support units of first and second guide rails having a link structure is weakened by the force of gravity with the passage of time and thus a cover unit is naturally opened and closed to cause the introduction of foreign materials into a main frame and that a link member has an X-shaped structure, occupies a large volume of the first and second guide rails, and is heavy to cause the difficulty in being applied to LED lighting devices for home and offices, a downward opening and closing device for an LED lighting device according to the present invention is composed of a reverse L-shaped support bracket (10), a two-blade type support bracket (20), and a slot type elastic spring unit (30). The downward opening and closing device for an LED lighting device can open and close an LED module frame downward with respect to an LED lighting device cover by the elastic force and restoring force thereof without the interference of a ceiling and a bolt coupling unit when opening and closing the LED module frame, thereby improving AS efficiency by 80% than before by enabling a worker to perform the repair and replacement of failed parts directly under the LED lighting device, can be customized according to the size and weight of the LED lighting device, and can be compatibly installed in all of the LED lighting devices for home, offices, and industry through bolt coupling and adhesives to have high compatibility. |
