Description

Down light {The down light}

The present invention relates to a down light embedded in a space above a ceiling of a room, and more particularly, a frame having a lamp coupling socket is embedded in a space above a ceiling so that the frame does not protrude below the ceiling. The reflection shade is inserted and inserted into the inside through the lower end of the frame, and an annular finishing member contacting the bottom surface of the ceiling in contact with the bottom surface of the frame and the transparent or translucent light transmitting plate is in contact with the frame. And a down light fixedly coupled to the lower end of the reflection shade, so that the replacement member combined with the reflection shade and the light transmitting plate can be easily separated from the frame by rotation for replacing the lamp or cleaning the reflection shade. And downlights that allow for simple detachable coupling of the reflector.

The greatest discovery in human life was fire, and as it became possible to illuminate the living space as a fire, it was no longer restricted by activity time and scope of activity, and human civilization began in earnest.

In other words, one of the most needed industrial products in today's daily life is the lighting fixture that illuminates the room, as lighting by fire to illuminate the living space can be called the beginning of civilization. Unable to imagine modern life without lighting fixtures.

Such lighting was started from natural fires that were found by chance in nature, and then artificial fires caused by the combustion of oil, candles, and gas were used as lighting.In 1870, the incandescent lamp was invented and modern lighting using electricity began. Since then, various electric lighting fixtures such as sodium discharge lamps, fluorescent lamps, etc. have been developed to this day.

Lighting can be largely divided into indoor and outdoor lighting, and lighting fixtures for indoor lighting can be classified into an attachment type lighting fixture that is fixedly attached to a wall or a ceiling, and a stand type lighting fixture that can freely move its position.

Representative of the attachment type lighting fixture of the lighting fixture, as shown in Figure 1, the lighting fixture that is coupled to the tube 12 to the bottom side of the reflector 11 fixed to the wall or ceiling, that is, an initial fluorescent lamp is an example. With the improvement of living standards, such fluorescent lamps are rarely used in recent years.

In other words, as living standards improve and large apartments such as apartments are built, the desire for interior decoration grows, so that lighting and decorative effects, such as chandeliers, can be obtained, rather than simply as lighting fixtures. Although it is not a chandelier but a general lighting fixture, the exterior is designed to serve as an interior accessory as much as possible.

As a result, incandescent lamps and fluorescent lamps in which only a plate-shaped reflector is provided and a light source such as an incandescent lamp or a tube tube are directly exposed to the outside have been rarely used in general homes.

Therefore, a new design lighting fixture is made so that a decorative effect can be obtained without exposing the light source, and is widely used in general homes. A typical example is a lighting fixture equipped with a light source inside a box-shaped case instead of a plate-shaped reflection shade.

As illustrated in FIG. 2, the lighting fixture to which the box-shaped case is coupled includes: an upper plate 21 attached to a wall or a ceiling and to which a light source is detachably coupled to a bottom surface thereof; It is a structure consisting of a lower case 22 of the upward open type that is detachably coupled to the bottom of the upper plate 21, and is mainly used for home use.

However, the lighting fixture combined with the box-shaped case is fixed to the ceiling, so that the ceiling is relatively low compared to the case where the lighting fixture is not installed.

In addition, since the light fixture protrudes from the flat ceiling, it not only reduces the aesthetics of electric shock in some places, but also moves the light fixture having a lower height than the ceiling when moving a high object indoors. May be damaged.

Therefore, in recent years, the ceiling of living rooms or public places is installed in the interior space above the ceiling and down light does not protrude below the ceiling is installed.

As shown in Figures 3 and 4, the conventional down light,

A ring-shaped inner rib 31A having a plurality of bent pieces P protrudes from the upper surface adjacent to the irradiation hole H penetrating the central portion, and a ring-shaped outer rib of which the upper surface is in contact with the bottom surface of the ceiling C. An annular closing member 31 which protrudes from the outer edge portion of the upper surface outside the inner rib 31A, 31B;

A transparent or translucent disc-shaped light transmitting plate 32 laminated on an upper surface of the finishing member 31 between the inner rib 31A and the irradiation hole H;

It consists of a body 33A which is enlarged toward the bottom along the axial direction and opened in both up and down directions, and an annular coupling flange 33B provided on the outer circumferential surface of the lower end of the body 33A, and the coupling flange 33B. A reflection shade 33 coupled to the finishing member 31 in such a manner that the bending piece P is bent in a state of being laminated on the upper surface of the light transmitting plate 32;

It is embedded in the space above the ceiling (C), the lamp (L) coupling socket (S) is coupled to the inside, a plurality of close contact elastically in close contact with the outer peripheral surface of the lower end of the reflecting shade 33 forcibly inserted A frame 34 having a piece 34A provided on an inner circumferential surface of a lower end and having a laminated flange 34B laminated on an upper surface of the finishing member 31 between the inner and outer ribs 31A and 31B extending outward on a lower end of the outer circumferential surface. ; And the like.

In the conventional downlight configured as described above, the light transmitting plate 32, which is usually made of glass, is intended to prevent the lamp L from being directly seen by the human eye or to obtain a separate lighting effect. When the light transmitting plate 32 is not used, the inner space and the outer space of the reflector 33 are connected to each other, and the lamp L is replaced by putting a hand in the inner space of the reflecting shade 33 or There is no problem cleaning the inside.

However, in the case of the downlight in which the light transmitting plate 32 is used, the finishing member 31 in which the reflector 33 and the light transmitting plate 32 are combined is first separated from the frame 34 and then the frame 34 2) to separate the reflection shade 33 from the finishing member 31 separated from the), there is a problem that the primary and secondary separation operation is not easy.

That is, a plurality of closely contacted pieces 34A provided on the inner peripheral surface of the lower end of the frame 34 are elastically in close contact with the outer peripheral surface of the lower end of the reflection shade 33 inserted into the frame 34 by interference fit. Pulling the finishing member 31 with a force greater than the elastic adhesive force between the pieces can be removed from the frame 34, the finishing member 31 combined with the reflection shade.

However, the finishing member 31 to which the reflection shade 33 is coupled is inserted into the inner rib 31A of the finishing member 31 into the lower inner diameter portion of the frame 34 and at the outer edge of the finishing member 31. The top surface of the provided outer rib 31B is in contact with the bottom surface (or ceiling surface) of the ceiling, and the height of the outer rib is approximately 5 mm or less.

That is, since the height of the finishing member projecting downward from the bottom of the ceiling is 5 mm or less, when the outer peripheral surface of the outer rib 31B having insufficient protrusion height is held by hand, sufficient force cannot be applied to the finishing member 31 by using only a hand. Is difficult to separate from the frame 34.

Therefore, a screwdriver or the like is forced to insert the tool end between the top surface of the outer rib of the finishing member and the bottom surface of the ceiling, and there is an inconvenience of separating the finishing member from the frame after opening the gap so that an appropriate gap is formed between the outer rib and the ceiling.

In addition, the conventional finishing member is generally made by drawing a steel sheet and then plated with chromium or the like on the surface thereof to improve aesthetics and prevent rust. In order to separate the reflective shade from the finishing member, It is necessary to straighten the bent piece that has been bent, and there is an inconvenience of using a separate tool such as a screwdriver, a long nose plier, etc., because it cannot be unfolded by hand.

In addition, the surface of the finishing member may be scratched by friction or contact with a tool during the second separation process as described above, and the surface of the steel sheet is exposed to the atmosphere by the scratches, thereby causing rust. Not only the aesthetics but also the whole aesthetics of the ceiling can be harmed.

In other words, the conventional downlight using the light transmitting plate is used to remove the finishing member combined with the reflecting lamp and the light transmitting plate from the frame to replace the lamp or to clean the reflecting lamp, and also to remove the reflecting lamp from the finishing member again. Uncomfortable.

In addition, since the plated steel sheet is used as the material of the finishing member, surface rust is easily generated by plating peeling or scratch marks, so the service life of the finishing member is remarkably shortened. For the aesthetics of the battlefield, there is an inconvenience of having to replace the surface rust finish member quickly.

The present invention was devised to solve all the problems of the separation side of the conventional downlight using the light transmitting plate, and separates the finishing member from the frame installed in the space above the ceiling so as not to protrude to the bottom of the ceiling, It is an object of the present invention to provide a down light that can be easily removed using only a hand without using any tool in the second separation process of separating the reflection shade from the separated finishing member.

In addition, there is another object of the present invention to provide a downlight combined with a finishing member that does not generate surface rust even if there is surface damage such as scratch marks on the surface.

The object of the present invention is achieved by a locking groove provided on the inner rib of the closing member and the locking projection provided on the inner peripheral surface of the lower end of the frame.

In addition, yet another object of the present invention is achieved by the synthetic resin of the finishing member.

In the down light of the present invention, since the frame and the closing member are combined by a rotational locking type rather than an interference fit type, the finishing member can be easily removed from the frame by simply rotating the finishing member without using a separate tool. There is an advantage.

The material of the finishing member is changed from metal to synthetic resin, and the inner rib of the finishing member is provided with a resilient locking piece, and the locking piece is elastically hung on the lower end of the reflector, so that the locking piece is pushed elastically. Not only can the reflection shade be easily separated from the finishing member, but there is an advantage that surface rust does not occur at the source.

The present invention is composed of a frame which is installed on the bottom of the ceiling (ceiling surface), and an annular finishing member that is coupled to the lower end of the ceiling and exposed to the outside in contact with the bottom of the ceiling to affect the aesthetics of the ceiling. It's about downlights.

The downlight of the present invention, in particular, relates to a downlight that can be easily removed from the embedded frame, the annular finishing member in contact with the bottom surface of the ceiling; A light transmitting plate laminated on a central portion of the finishing member; A reflection shade coupled to the finishing member in a state of being laminated to an upper edge portion of the light transmitting plate; A frame installed over the bottom of the ceiling and having a reflection shade inserted therein; .

The down light of the present invention configured as described above has a structural feature of the present invention that is different from the conventional down lights in the coupling structure of the finishing member and the reflector and the coupling structure of the finishing member and the frame.

The finishing member is a component that affects the appearance of the downlight and the aesthetics of the entire ceiling by exposing its bottom to the outside in contact with the ceiling.

The finishing member may have an annular rim having a width in a horizontal radial direction and having an irradiation hole as a hole through which light of a lamp passes; A pair of ring-shaped inner and outer ribs protruding concentrically from each other on a plan view along different virtual circumferences of the upper surface of the rim.

At this time, the inner and outer ribs are formed on the outer edge of the rim upper surface and the rim upper surface adjacent to the irradiation hole, respectively.

And the height of the inner rib is higher than the height of the outer rib, the inner rib is inserted into the inner diameter of the lower end of the frame and its outer peripheral surface is in contact with the inner surface of the frame, the top surface of the outer rib is in contact with the bottom surface of the ceiling.

In addition, the inner rib has a plurality of engaging pieces which can move elastically along the radial direction and the upper end as the free end, which is not fixed around the fixed lower end when the force is applied, and the inner one side of the inner rib at the same time. A plurality of locking grooves are provided, each of which is opened through the top surface of the rib.

At this time, the locking groove has a shape similar to the letter "b", the left and right length is longer than the upper and lower width, and the locking portion penetrating the inner rib; Opening to the upper end surface of the inner rib while penetrating the inner rib at one end in the longitudinal direction of the engaging portion, it consists of an inlet portion having a shorter left and right width than the upper and lower lengths.

The reflecting shade is made by drawing metal, for example, aluminum plate, and the upper and lower openings have an inner diameter that increases from the upper to the lower axial direction and the upper and lower ends are open. The annular coupling flange is extended toward the outside.

The coupling flange of the reflection shade is laminated on the upper surface of the finishing member rim, that is, the inner diameter of the inner rib of the inner rib positioned between the inner rib of the finishing member and the irradiation hole. Since the bottom surface of the reflecting shade coupling flange is caught by the engaging piece provided on the rib, the coupling flange of the reflecting shade cannot be laminated on the upper surface of the rim of the finishing member, and thus is separated from the upper surface of the rim.

As described above, when the reflection shade is pressed while the coupling flange of the reflection shade is hanging on the locking piece, the upper portion of the locking piece of the inner rib is pushed elastically, and the coupling flange of the reflection shade can be completely lowered to the upper surface of the rim of the finishing member, and stacked. As the engaging flange of the reflecting shade is lowered to the upper surface of the rim, the engaging piece that has been pushed back to its original position returns to its original position. When lifting the reflecting shade, the upper surface of the engaging flange is caught by the engaging piece and the reflecting shade cannot be separated from the finishing member. It becomes a state.

In other words, the reflecting shade is not separated from the finishing member when it is not pushed outward by applying a force to the locking piece of the finishing member inner rib.

The frame has a downwardly open inner space so that the reflection shade can be inserted upward, and a plurality of locking protrusions protrude from the inner peripheral surface of the lower end, and an annular laminated flange extends toward the outer side in the radial direction at the lower end thereof. Is laminated on the upper surface of the rim located between the inner and outer ribs of the finishing member.

At this time, the upper surface of the rim located between the inner and outer ribs and the bottom of the laminated flange may be in contact with or apart from each other while the frame and the finishing member are combined.

And the locking projection provided on the inner peripheral surface of the lower end of the frame is detachably inserted into the engaging groove formed in the inner rib of the closing member, the locking groove of the inner rib of the closing member and the locking projection of the inner peripheral surface of the frame are combined as follows.

If the frame is fixed and the closing member is separated, first, adjust the position by rotating the finishing member so that the up and down positions between the frame locking protrusion and the closing member engaging groove inlet are adjusted, and then the finishing member is framed. The inner rib of the closing member is inserted into the lower inner diameter of the frame while being pushed to the side so that the locking projection of the inner peripheral surface of the lower end of the frame enters the inlet of the locking groove so as to be positioned at the lower end of the inlet.

As described above, when the closing member is rotated while the locking protrusion of the frame is positioned at the lower end of the inlet of the closing member, the locking protrusion of the frame moves from the upper opening of the locking groove to the upper closed locking portion, thereby closing the locking member. The locking portion of the frame is in a state of being caught by the locking protrusion of the frame.

Details of the effects and the resulting effects, including the object and technical configuration of the present invention will be clearly understood by the following description with reference to the drawings showing a preferred embodiment of the present invention.

5 is an exploded perspective view of an embodiment of the downlight of the present invention, and FIG.

As shown in the downlight of the present invention,

Irradiation hole (H) is formed in the center portion and an annular rim (51A) having a width in the radial direction, and the inner and outer ribs protruding to form concentric circles with each other along the imaginary circumference on the upper surface of the rim (51A) 51B) and 51C, a closing member 51 having a plurality of locking grooves G and locking pieces B in the inner ribs 51B;

A disc-shaped light transmitting plate 52 laminated on the upper surface of the rim 51A between the inner rib 51B and the irradiation hole H of the finishing member 51;

It consists of an annular coupling flange 53B extending along the radial direction horizontally from the outer peripheral surface of the lower end of the body 53A and the body 53A which is enlarged toward the lower part from the upper side in the axial direction and is opened. A reflector 53 which is elastically hung on the engaging piece B of the finishing member inner rib 51B in a state where the flange 53B is laminated on the upper surface of the light transmitting plate 52 and coupled to the finishing member 51;

The reflection shade 53 has an inner space in which the lower end is opened to be inserted upward, a plurality of locking projections (E) that is caught in the locking groove (G) of the inner rib (51B) of the finishing member protrudes on the inner peripheral surface of the lower end, The annular laminated flange 54A, which is laminated on the upper surface of the rim 51A between the inner and outer ribs 51B and 51C of the finishing member, extends horizontally outward from the outer peripheral surface of the lower end and is coupled to the lamp L in the inner space. A frame 54 having a socket S; .

At this time, the outer rib 51C of the closing member 51 is aesthetically preferable to be formed on the edge of the upper surface of the rim 51A, the inner and outer ribs 51B, 51C is a virtual circumference of the upper surface of the rim 51A. It may protrude along the whole but may protrude intermittently.

And each of the engaging pieces (B) provided on the inner rib (51B) of the closing member 51 is formed between two adjacent separating grooves G 'for cutting the inner end portion from the upper end of the inner rib to the lower end side, and the engaging piece ( When the engaging step J is protruded on the inner surface of B) and the lifting shade 53 is lifted while the inner rib 51B is fixed, the upper surface of the coupling flange 53B of the reflecting lamp cannot be separated by the engaging step J. It is a structure.

In addition, the locking groove G provided on the inner rib 51B of the closing member 51 has a left and right lengths along the circumferential direction of the inner ribs longer than the upper and lower widths along the width direction of the inner ribs. A locking portion G1 penetrating therethrough; Opens to the upper end of the inner rib while penetrating the inner rib at one end in the longitudinal direction of the engaging portion G1, and has a shorter left and right width along the circumferential direction of the inner rib than the upper and lower lengths along the width direction of the inner rib. Inlet portion G2; .

However, the comparison of the length and width of each of the locking portion G1 and the leading portion G2 is not an absolute, but an easy explanation. The relative ratio of the length and width varies depending on the size of the locking protrusion and the position of the leading portion. The important point is that the locking portion G1 and the leading portion G2 form a shape of "b", but the angle between the locking portion G1 and the leading portion G2 is not necessarily at right angles.

In addition, the locking protrusion E of the inner circumferential surface of the frame 54 moves to the lower end through the open upper end of the inlet part G2, and then moves back to the locking part G1 so that the locking protrusion E is locked to the locking part G1. ) Is caught in the vertical direction.

At this time, it is also preferable to incline the locking portion G1 downward with respect to the horizontal direction in a direction away from the inlet portion G2, and as the locking portion G1 rotates the finishing member 51 when the locking portion G1 is inclined. The locking protrusion E of the closing member 51 and the frame 54 can be closer to the closer to the lower end side of the closing member 51.

And by providing a plurality of unevenness (T) on the ceiling surface of the locking portion (G1) so that the locking projection (E) can stably maintain its position without moving itself along the inclined ceiling surface of the locking portion (G1). You may.

When the locking groove G has a "b" shape as described above, the coupling and disengagement of the closing member 51 is always performed only in a predetermined rotation direction, as shown in FIG. It is also desirable to make a "ㅗ" shape.

As described above, in the case of having a “ㅗ” shaped locking groove G in which the locking portions G1 are formed on both sides of the leading portion G2, the locking projections E of the frame 54 are led to the leading portions G2. In the state positioned at the bottom of the) can be combined with the frame and the finish member by rotating the finish member in any direction left or right.

In addition, the finishing member 51 exposed to the outside in contact with the ceiling is preferably made of synthetic resin, not metal, and may be plated on the surface as necessary.

In addition, the outer ribs 51B and the laminated flanges 54A respectively provided on the finishing member 51 and the frame 54 are for improving appearance, and may not be provided as necessary.
