Description

Ceiling lighting fixtures with improved installation and construction convenience}

The present invention relates to a ceiling type lighting fixture with improved installation and construction convenience.

In general, lighting is installed on the ceiling, and includes a frame in which a light source is housed, and a cover detachably coupled to the frame.

Looking at the installation process of such lighting, after supporting the frame on the ceiling, the frame is fixed using screws. When the frame is fixed to the ceiling, the wires coming out of the ceiling through the frame are coupled to the ballast placed on the frame. When the wire is coupled to the ballast, the cover is supported on the end of the frame, and then the cover is coupled to the frame by fastening the front corners of the cover to the frame using bolts, respectively.

However, the conventional lighting as described above does not have a good visual aesthetic as the bolts fastened to fix the cover are exposed to the outside of the cover, and the operator tightens the bolts while holding and supporting the cover with one hand. Since the cover must be fixed while going, the installation work is not easy, and in the process of fastening the bolt, the cover is lost from the hand, and the cover falls or the bolt is lost.

In addition, since the conventional lighting lamp is completely fixed to the ceiling, when parts need to be replaced or other work needs to be performed, there is a problem in that the operator has to perform the work while maintaining an uncomfortable posture while climbing up a ladder or the like.

In addition, in the conventional lighting, a gap is formed between the cover and the ceiling so that the inside of the cover is not completely sealed, and dust, insects, etc. penetrate into the inside of the cover to deteriorate lighting performance or contaminate the cover. there was.

In addition, conventional lighting has a problem in that a bezel protecting the front edge of the cover is formed in a too thick shape to cover a part of the front area of the cover that diffuses light, thereby reducing light efficiency. In addition, there is a problem that the front area of the cover looks relatively narrow due to the bezel.

The elastic stopper ring 432 is formed of an elastic material capable of transforming its appearance, is coupled to the outer surface of the slide protrusion 431, and is press-fitted between the slide protrusion 431 and the slide groove 413, so that the flow of the slide protrusion 431 can limit

For example, the inner diameter of the elastic stopper ring 432 may be smaller than the outer diameter of the slide protrusion 431 . Accordingly, the elastic stopper ring 432 can maintain a more firmly coupled state to the outer surface of the slide protrusion 431 . The outer diameter of the slide protrusion 431 may be larger than the width of the slide groove 413 . After the slide protrusion 431 moves, the elastic stopper ring 432 is press-fitted between the slide protrusion 431 and the slide groove 413 to fix the slide protrusion 431 .

8 is a schematic cross-sectional view of a cover fixing member according to an embodiment of the present invention.

Referring to FIGS. 5 and 8 , the housing 3 may further include a cover fixing member 33 .

The cover fixing member 33 may be detachably coupled to the first locking ring 412 and pressurize the first locking ring 412 to limit the flow of the first locking ring 412 .

The cover fixing member 33 may include a ring support bracket 331 , a cage 332 , an elastic member 333 , and press ball members 334 .

The ring support bracket 331 is coupled to the outer surface of the housing 3, the inside is penetrated and the first locking ring 412 is inserted into the inside, and then hooked and supported at the top.

The inside of the ring support bracket 331 communicates with the ring insertion hole 331A into which the first locking ring 412 is inserted, and the ring insertion hole 331A to communicate with the cage 332, the elastic member 333, and the press ball member. Accommodating grooves 331B in which the s 334 are accommodated may be formed.

The cage 332 is accommodated in the receiving groove 331B, and the pressing ball members 334 can be rotatably accommodated therein. Also, the cage 332 may be formed to have the same size as the receiving groove 331B and move along the inner surface of the ring support bracket 331 .

The elastic member 333 may be accommodated in the receiving groove 331B and elastically support the cage 332 toward the ring insertion hole 331A. For example, the elastic member 333 may be implemented as a coil spring.

The pressing ball members 334 may be rotatably coupled to the cage 332 .

The pressing ball members 334 may press and fix the first locking ring 412 accommodated in the ring insertion hole 331A while protruding outward from the receiving groove 331B by the cage 332 .

The pressing ball members 334 guide the movement of the first locking ring 412 while being rotated by the first locking ring 412 when the first locking ring 412 is coupled to or separated from the cover fixing member 33. You may.

At this time, the first locking ring 412 coupled to the cover fixing member 33 is in contact with the sleeve 41, and the first section 412A coupled to the sleeve 41 through the fastening means, and the first section 412A A second section 412B extending from and accommodated in the ring insertion hole 331A, pressurized and fixed to the pressing ball members 334, extending from the second section 412B, and bent to form an acute angle to form a ring A third section 412C hooked and supported by an end of the support bracket 331 may be included.

As such, according to the embodiment of the present invention, the bracket 2 is provided with a collapsible and retractable rotation unit 22, and the housing 3 is provided with a connection unit 31 that is hooked and supported by the rotation unit 22 in the form of tongs. , The user can easily install the housing 3 to the bracket 2 in a comfortable posture without using a ladder or screws, so that installation and installation convenience can be maximized.

In addition, since a part of the housing 3 is rotatably coupled to the bracket 2, and the other part of the housing 3 is detachably coupled to the bracket 2 through magnetic force, the parts are separated one by one while disassembling screws and the like. The housing 3 can be separated or combined from the bracket 2 as needed without a separation process, and through this, maintenance and management can be facilitated.

In addition, even when the housing 3 is separated from the bracket 2, since it is connected to the rotating part 22 and maintains a supported state, the user can work with both hands, thereby enabling stable installation and construction.

In addition, the cover 4 is not fixed to the sleeve 41 through a separate fastener such as a bolt, but is directly coupled to the sleeve 41, and a bezel is removed from the front surface of the cover 4 exposed to the outside space. Therefore, aesthetics and light efficiency are improved, and the lighting can visually look wider.

In addition, since the end of the cover 4 is in contact with the ceiling C so that the gap between the cover 4 and the ceiling C is airtight, the gap between the cover 4 and the ceiling C is completely sealed to prevent inflow of foreign substances or insects. Through this, it is possible to prevent degradation of lighting performance and contamination of the cover 4 .
