The present invention relates to a ceiling-mounted lighting for attaching to the ceiling of the living room, such as for indoor lighting, and more particularly, a floodlight cover covering the opening of the body in which a lamp or the like is embedded. By mounting so as to slide opening and closing with respect to the body relates to a ceiling-mounted lighting lamp that can be replaced very easily and safely without removing the floodlight cover from the body when replacing the lamp.

In general, lighting lamps used for indoor lighting are mostly attached to the ceiling for easy lighting. Such ceiling-mounted lighting lamps can be classified into an exposure type that directly exposes a lamp according to an illumination method and a closed type that indirectly lights by closing a lamp with a floodlight cover.

The exposure type is usually provided with a reflection shade to show a high lighting efficiency, but has the disadvantage of deteriorating the aesthetics of the room. In particular, in the case of fluorescent lamps are provided with accessories such as ballasts, the interior aesthetics are greatly damaged.

Therefore, in the case of the exposure type is mainly used incandescent bulbs, power consumption is very large. Of course, in recent years, the use of bulb-type fluorescent lamps have drastically reduced power consumption, but this also has to endure the lack of attention.

Accordingly, in the case of a lighting lamp having a plurality of lamps to illuminate a relatively large space such as a ceiling lamp, especially a living room, a closed type that incorporates a circular or rod-shaped fluorescent lamp in the body and shields the opening of the body with a floodlight cover. In general, the glare phenomenon, which is a characteristic of the fluorescent lamp, can be effectively prevented.

By the way, the conventional closed lamp is a type of screw fixing method for fixing the floodlight cover at the center of the body or at various places around the body, for example, when replacing the lamp by unscrewing each screw to separate the floodlight cover from the body After replacing the lamps and tightening the screws of the floodlight cover to the body again, the lamp replacement work was very complicated and unstable.

In particular, since it is attached to the ceiling, it is more difficult to work while standing on a chair, looking up, looking up, and the risk of dropping the cover or lamp during the lamp replacement is very high.

On the other hand, Korean Utility Model Registration No. 0330075 discloses a lamp cover assembly structure that can be easily opened and closed in a sliding manner with respect to the floodlight cover to solve this problem.

This prior art forms inserts on both sides of the opening of the body made of metal plate and forms mounting brackets with magnets on the outside of the main body to cover the edges of the glass cover after inserting both edges of the glass cover into the inserts. An exterior cover having a slot in the center is attached to the magnet of the mounting table.

However, this conventional technology, although the glass cover is coupled to the main body by sliding to solve the clutter of screwing, the glass cover must be completely separated from the main body when replacing the lamp, and in particular, the glass cover with a separate exterior cover for aesthetics. There is still a problem that the lamp replacement work is cumbersome to surround the edge of the bar.

In addition, since the exterior and the glass cover have to be separated from the main body, there is no fear of dropping them, and there is an inconvenience in that the two covers must be removed even when only one of the fluorescent lamps is replaced.

The present invention has been made in view of the above-mentioned conventional problems, and in lighting for shielding the opening of the main body on which the lamp is mounted with the floodlight cover, the opening of the main body is made very simple by slidingly opening and closing the floodlight cover to the main body. It is an object of the present invention to provide a ceiling-mounted lamp that can be opened and closed and the lamp can be easily replaced without removing the floodlight cover from the main body.

Another object of the present invention is to perform the lamp replacement operation more conveniently, since only part of the main body in which the lamp to be replaced is installed can be selectively opened and closed, without opening the opening of the main body completely during lamp replacement. It is to provide a ceiling light that can be.

In order to achieve the above objects, the ceiling-mounted lighting lamp according to the present invention includes a central main part and two subs each extending from opposite ends of the main part with a width and height smaller than the main part and the main part. a main body comprising a sub part and fixed to the ceiling by mounting at least one electric component such as a socket and a ballast on the main part and each sub part; A lamp mounted to the main part of the main body and the socket of each sub part; An outer rail, an intermediate rail coupled through a plurality of first guide balls in the outer rail, and an inner rail coupled through a plurality of second guide balls in the intermediate rail, the outer rail being a main part of the main body And at least three pairs of slide rails installed on the corresponding opposite edges of each sub-part, next to each other, and the middle and the inner rails are drawn out to the outside. A plurality of slide brackets each of which is fixed to an inner rail of each slide rail pair in a vertical direction to form skirts on both sides of the main part and each sub part of the main body, respectively; A plurality of main part and sub part light emitting covers which are fixed to lower ends of each pair of slide brackets to individually shield openings of the main part and two sub parts of the main body, wherein the main part light emitting cover overlaps the top of the sub part light transmitting cover. It is characterized in that the opening.

According to one preferred feature of the present invention, the main light-transmitting cover is divided into two to be opened and closed to face each other so as to shield only a part of the main part of the main body, a pair of slide rails are provided in each of the opening and closing direction of the main part to each other The floodlights operate individually to improve the safety and convenience of lamp replacement.

According to another preferred feature of the present invention, a fixing socket having an assembling hole vertically and spaced apart from the slide bracket and having at least two elastic fastening pieces around the assembling hole so as to protrude a free end into the assembling hole, A belt-shaped fastening band each having a male thread penetrating the floodlight cover, and a threaded head respectively screwed into the male screw of the fastening band penetrating the floodlight cover, are fitted in the fixing hole of the fixing socket, and locked by the elastic locking pieces. It is equipped with a plurality of fixing plugs to secure the floodlight cover to the slide bracket simply by one-touch method.

Accordingly, the present invention can open and close the floodlight cover very simply and easily replace the lamp without removing the floodlight cover from the main body, as well as without opening the opening of the main body completely during lamp replacement. Only a part of the main body in which the lamps to be replaced can be selectively opened among the two lamps, so that the lamp replacement work can be more conveniently performed, thereby having a great effect on improving the reliability and stability of the lamp and the ease of use.

Such specific features and other advantages of the present invention will become more apparent from the following description of the preferred embodiments with reference to the accompanying drawings.

1 to 4, the first embodiment of the ceiling lamp 1 according to the present invention, the main body is fixed to the ceiling by mounting the electrical components such as a plurality of sockets 15 and ballast (not shown) ( 10), a rod-shaped fluorescent lamp 20 mounted on the socket 15 of the main body 10, a slide rail 30 mounted side by side at both edges of the main body 10, and two slide rails. A pair of slide brackets 40 fixed to the 30 and entering and exiting the main body 10, and a light transmitting cover 50 fixed to the lower ends of these slide brackets 40 to open and close the opening 10a of the main body 10. ).

The main body 10 is made of a metal plate, and the skirt 11 is provided on two sides corresponding to each other among four sides so that both sides located in the opening and closing direction of the bottom surface and the floodlight cover 50 are opened. do.

Here, although not shown separately, the skirt 11 may be provided on all four sides of the main body 10. In this case, the two ends of the slide rail 30 positioned in the opening and closing direction of the floodlight cover 50 allow the slide rail 30 to enter and exit. A slit is provided for this.

Fastening plates 12 for fastening the slide rails 30 with screws 39 are respectively joined to the inner surfaces of the two skirts 11. This is to prevent this because when screwing the slide rail 30 directly to the skirt 11 with the screw 39, the screw 2 protrudes out of the skirt 11 to harm the aesthetics.

On the other hand, preferably in the center of the transmission cover opening and closing direction of the main body 10 in order to prevent the inside of the main body 10 is exposed by a gap formed in the boundary portion of the two transparent cover 50 described later ( 13) is installed in a direction perpendicular to the opening and closing direction of the floodlight cover.

The shielding plate 13 is positioned at the same height as the skirt 11 of the main body 10 by the bracket 14, and preferably made of the same material as the floodlight cover 50 so as not to impair illumination.

Fluorescent lamp 20 is provided with a plurality for easy illumination is disposed at a suitable interval on the main body 10 in the opening and closing cover of the floodlight. In the illustrated embodiment, four are provided and arranged at equal intervals.

The slide rails 30 are fastened by screws 39 in a state of standing up on the inner surfaces of the two skirts 11 of the main body 10. The slide rail 30 is different in quantity and arrangement according to the number of the floodlight cover 50. For example, in this embodiment, two floodlight covers 50 are formed as described below, and are provided at both ends of the skirt 11. Each pair is provided.

Meanwhile, as illustrated in FIGS. 5A to 7, the slide rail 30 includes an outer rail 31 on a channel fastened by a screw 39 to the face plate 12 of the main body 10, and An intermediate rail 32 on the channel that is movably assembled through the plurality of first guide balls 34 in the outer rail 31, and a plurality of second guide balls 35 also in the intermediate rail 32. It consists of a three-stage rail with an inner rail 33 on the channel which is assembled to be movable through it.

Both ends of the outer rail 31 and the intermediate rail 32 are provided with stoppers 36 and 37 for preventing the intermediate rail 32 and the inner rail 33 from being separated. Among them, the stopper 36a provided at the rear end of the outer rail 31 is composed of a rubber block having an appropriate elasticity and height to prevent the rear rail from being pulled out of the middle rail 32 and at the time of closing the floodlight cover 50. It also serves to prevent the light-transmitting cover 50 from being naturally drawn out without an external force by being elastically deformed into the inner rail 33 and fixing the inner rail 33 in a reduced state.

At the bottom of the intermediate rail 32, beads 32a are formed in the longitudinal direction of the intermediate rail 32 so that the outer rail 31 may move without interfering with the screw 39 fastening to the main body 10.

The first guide ball 34 and the second guide ball 35 are accommodated in retainers 38a and 38b, which maintain them at regular intervals, respectively. It is interposed between the inner rails 32 and 33.

The slide bracket 40 is made of, for example, a metal plate and is integrally fastened by the screw 39 to the inner rail 33 of the slide rail 30 and moved together with the inner rail 33. At one end of the slide bracket 40, a flange 41 for fastening the light transmitting side plate 60, which shields the two side openings 10b of the main body 10, with the screw 43 is bent, and at the bottom thereof, light transmitting is performed. At least two fastening tabs 42 for fixing the cover 50 with screws 44 are bent at intervals.

Although not shown separately, the slide bracket 40 may be made of a light-transmissive material, such as acrylic, such as the translucent cover 50.

The floodlight cover 50 may be made of a single body, but preferably includes two bodies separated to cover the openings 10a of the body 10 by one half as shown.

That is, when the floodlight cover 50 is made of a single body, when the lamp is replaced, the floodlight cover 50 must be completely opened to either side to open all the openings 10a of the main body 10, and thus the floodlight cover 50 The drawout length of the bar is excessively long, which can be exerted on the main body 10 and the slide rails 30 by its own weight. A part necessary for lamp replacement while minimizing the drawout length of the floodlight cover 50 is opened in a stable state. It is preferable to be divided into two bodies so as to partially open the bay.

The light transmitting cover 50 may be made of glass, or may be made of a transparent synthetic resin such as acrylic, as long as it can transmit light generated from the fluorescent lamp 20.

The remaining reference numeral 70 is a fixing bracket for fixing the main body 10 to the ceiling (R), 33a is to maintain the inner rail 33 of the slide rail 30 to the intermediate rail 32, if necessary It is a locker that can be separated from the intermediate rail (32).

According to the first embodiment of the ceiling-mounted lighting lamp 1 according to the present invention configured as described above, the floodlight cover 50 for shielding the lower surface opening 10a of the main body 10 is three-stage without being completely separated from the main body 10. Since the slide rail 30 is slidably coupled to the main body 10, the opening 10a of the main body 10 can be opened and closed very easily when necessary.

Thus, for example, when the fluorescent lamp 20 is to be replaced with a new one, the inside of the main body 10 is opened by lightly pushing the floodlight cover 50 to the outside, and in this case, the floodlight cover 50 slides. Since the rail 30 is stably supported by the main body 10, the fluorescent lamp 20 can be replaced immediately after opening the floodlight cover 50 without a separate operation.

In addition, even after the fluorescent lamp 20 is replaced, the opening 10a of the main body 10 can be shielded again by an extremely simple operation of lightly pushing the open light cover 50 toward the main body 10.

At this time, the rubber stopper 34a provided at the rear end of the outer rail 31 of the slide rail 30 is compressed and deformed and fitted into the inner rail 33 to press-support the inner rail 33, thereby applying an appropriate external force. Unless it is transparent, the floodlight cover 50 does not naturally open and remains safely closed.

Furthermore, in the present invention, the floodlight cover 50 is divided into two bodies, so that each floodlight cover 50 is individually handled by only one half of the opening 10a of the main body 10 so that the opening and closing operation is easier. In addition, in particular, when only a part of the lamp replacement of the plurality of fluorescent lamps 20, the main body 10 is not opened completely, it can be easily replaced by only partially opening the corresponding part.

8 and 9 illustrate another structure of fixing the floodlight cover 50 to the slide bracket 40 in a one-touch manner in the ceiling lamp 1 according to the present invention.

To this end, two fixing sockets 81 are spaced apart from the slide bracket 40, and a fixing plug 82 fitted into each of the fixing sockets 81 is protruded from the floodlight cover 50.

The fixing socket 81 vertically has an assembly hole 83 into which the fixing plug 82 is fitted, and at least two elastic fastenings whose free ends protrude appropriately into the assembly hole 83 around the assembly hole 83. It has a piece 84a integrally. Note that the two resilient retaining pieces 84a may be configured separately from each other, or may be composed of both ends of the approximately C-shaped leaf spring 84 as shown.

The leaf spring 84 forms a coupling groove 81a in a direction perpendicular to the assembly hole 83 in the body of the fixed socket 81, and is fitted into the coupling groove 81a so that both ends thereof are assembled with the assembly hole 83. Protrude inward from the perimeter.

The fixing socket 81 has a flange 85 on both sides of the body is fastened to the slide bracket 40 by a screw 89.

The fixing plug 82 has a spherical locking head 86 that is fitted to the assembly hole 83 of the fixing socket 81 at the front end and is supported by the elastic locking piece 84a. 82a) is securely fastened to the floodlight cover 50.

The fixing plug 82 may be fixed to the floodlight cover 50 by bolts separately, but preferably, a male screw penetrating the floodlight cover 50 at both ends of one band-shaped fastening band 87 as shown in FIG. 88 is integrally bonded to each other to be engaged with the male screw 88 of these fastening bands 87.

This is to ensure a safer use by blocking the safety accident that can be caused by the user inadvertently dismantle the screw when the fixing plug 82 is fixed individually with a conventional screw.

The floodlight cover mounting structure having such a configuration is provided by pressing the floodlight cover 50 lightly so that the fixing plug 82 is fitted into the assembly hole 83 of the fixing socket 81 mounted on the slide bracket 40. 83, after the elastic locking pieces 84a protruding into the elastically deformed by the locking head 86 of the fixing plug 82, and the fixing plug 82 is completely inserted into the assembly hole 83, the restoring elasticity By returning to the initial state, the neck cover of the locking head 86 is supported to fix the floodlight cover 50.

Therefore, it is possible to reliably mount the floodlight cover 50 to the slide bracket 40 only by a very simple operation, and can also reliably prevent safety accidents caused by carelessness of the user.

10 and 11 schematically show another structure of the first embodiment of the ceiling lamp of the present invention.

In this embodiment, in the configuration of the above-described embodiment, the center bar is positioned higher than the main body 10 in the center of the transmissive cover opening and closing direction of the main body 10 instead of the obstruction plate 13 so as to be interposed between the two transmissive covers 50. center bar: 90)

The center bar 90 is configured to have a cross section of various shapes such as square, triangular, and circular, and is fixed to the bottom of the main body 10 through a plurality of legs 92, and two floodlight covers 50 on both sides thereof. Has an insertion groove 91 into which the inner end of each side is fitted.

The center bar 90 may be made of a light transmitting material having the same material as that of the light transmitting cover 50, or may be made of any material such as metal or other opaque synthetic resin.

In this embodiment, it is possible to completely mask the exposure of the inside of the body 10 by completely shielding between the two transparent cover 50, as well as contribute to the aesthetics of the lamp (1).

12 to 16 show a second embodiment of the ceiling lamp according to the present invention.

In this embodiment, in the configuration of the first embodiment described above, the main body 110 has a relatively large main body 110, and the main part 110 in both opening and closing directions of the floodlight cover of the main part 110, as compared with the main part 110. Comprised of two sub-units 120 having a small width and height, the main unit 110 and the two sub-units 120 are respectively provided with a transparent cover 151, 152 to open and close independently, The floodlight cover 151 of the main part 110 is open to overlap the floodlight cover 152 of the sub-part 120.

This second embodiment may be configured in the same manner as the first embodiment described above except for some structural features as described above, but here the opening and closing of the floodlight covers 151 and 152 is shown to show the diversification of the embodiment. Unlike the first embodiment, the slide rail 30 is laid down on both sides of the bottom of the main body 100 and is described as a configuration installed.

Of course, the first embodiment described above also, as in the second embodiment, the slide rail 30 can be installed on the bottom of the body 10, of course, for convenience of description 2 to avoid overlapping description of the same structure It is to be noted that the structures of the four embodiments are merely shown and described differently.

Accordingly, in the second embodiment, the main body 100 is configured in a simple plateless form without a skirt, and the slide bracket 140 which fixes the floodlight cover 150 to the slide rail 30 is the main body in the first embodiment. It replaces the skirt 11 of (10).

However, in this case, since the slide rails 30 are laid down on both sides of the bottom of the main body 100, even if the fluorescent lamp 20 of the same size is used, the width of the main body 100 is larger than that of the first embodiment, and thus the lighting lamp as a whole. (1) is bound to grow.

Therefore, the main body 100 of the second embodiment is preferably mounted to prevent the increase in width by forming a channel 103 on both rear surfaces of the plate-shaped body 101 and mounting the slide rail 30 in the channel 103. The brackets 102 each have a constitution bonded in the opening and closing direction of the floodlight cover 150.

At this time, the body 101 may be configured as a single body and the L-shaped mounting brackets 102 may be bonded to both rear surfaces thereof, or as shown, the width of the body 101 may be equal to the width of the two mounting brackets 102. It may be configured by bonding a separate expansion plate 104 to cover the mounting bracket 102 on both ends of the body 101 after the mounting bracket 102 is bonded to both side ends.

As shown, when using a separate extension plate 104, the reinforcement skirt 101a may be configured at the edge of the body 101, which is more advantageous in terms of structural strength.

In addition, the slide bracket 140 which is fastened to the inner rail 33 of the slide rail 30 also has a slightly different configuration, and horizontally fastens the fastening plate 143 for fastening to the inner rail 33 on the inner side thereof. Have more.

The floodlight cover 150 may be fixed to the fastening tab 142 of the slide bracket 140 by, for example, the fastening band 87 and the nut 144 described above.

The above configuration is the same for both the main unit 110 and the sub-unit 120, the main unit 110 and the sub-unit 120 may be made of a single body, or may be made of a separate separate body and joined to each other have.

However, in the case of the light transmitting side plate 160 that shields the side of the light transmission cover opening and closing direction of the main body 100, the light transmitting side plate 162 mounted on the sub part 120 is the same as the sub part 120 as in the first embodiment. Although it is composed of a width and completely shielded, the light transmitting side plate 161 mounted on the main part 110 is divided into two so that the main part light cover 151 can be moved above the sub part 120, respectively, on both ends of the width direction. Attached.

In the case of the second embodiment of the present invention, when the space to be illuminated has a rectangular shape, the sub part 120 may be extended in a long direction to uniformly illuminate the entire body while having a unique and beautiful appearance. In particular, the main body 100 may be divided into three parts. Since the partitions can be opened and closed respectively, the replacement of the fluorescent lamp 20 can be performed more easily.

That is, in the case of replacing the fluorescent lamp 20 of the sub-unit 120, as shown in FIG. 17A, only the floodlight cover 152 of the sub-unit 120 needs to be opened and replaced, and the fluorescent lamp of the main unit 110 ( 20), as shown in Fig. 17B, only the main part floodlight cover 151 can be exchanged simply by leaving the sub-parts 120 at both ends as they are.

Here, although not separately illustrated, the main part floodlight cover 151 of the second embodiment may also be divided into two bodies that are open to both sides as in the first embodiment, and in this case, the main body 100 is divided into four. The part can be partially opened to make the lamp replacement easier.

As described above, according to the ceiling-mounted lighting lamp according to the present invention, in the lighting lamp having a structure that shields the lamp with the floodlight cover, the lamp can be opened and closed extremely easily with respect to the main body, without having to remove the floodlight cover from the main body. The lamp can be replaced very easily and easily.

In addition, it is possible to selectively open only a part of the main body in which the lamp to be replaced is installed among the plurality of lamps without completely opening the opening of the main body when replacing the lamp, so that the lamp replacement operation can be more conveniently performed.

Therefore, the present invention has a very excellent effect that greatly contributes to the improvement of the reliability and stability of the lamp and the ease of use.
