Description

Lighting fixtures {LIGHT DEVICE}

Embodiment of the present invention mainly relates to a lighting fixture is installed on the ceiling to illuminate the place of use.

In general, a luminaire that is directly installed on the surface of the ceiling, that is installed so as to be suspended from the lower part of the ceiling, or embedded in the interior of the ceiling, the case has an open bottom structure and shields the open bottom of the case It includes a light transmissive cover, the light source is accommodated in the inner space formed by the case and the cover.

Here, the cover and the case are fastened to each other by screwing. For screwing, the fastening screw head or fastening nut is exposed under the cover.

Such a prior art has a problem that the fastening screw head or the fastening nut exposed to the lower side acts as a factor that inhibits the aesthetics of the lighting fixture. The fastening screw head or the fastening nut may be decorated for the purpose of preventing the impairment of the appearance of the luminaire, but the manufacturing process of the fastening screw or the fastening nut is complicated by the addition of the decorative process and the manufacturing cost must be increased.

In addition, in the prior art, when unfastening the fastening screw or the fastening nut for maintenance and repair, such as replacing the light source, the operator looks at the fastening screw head or the fastening nut side (that is, the ceiling side) exposed to the lower side. There is a problem that must be kept quite inconvenient because it must be maintained. In addition, the worker must hold the cover with one hand to prevent the cover from falling off, and only the other hand must loosen the fastening screw or the fastening nut. Both hands cannot be used to loosen the fastening screw or the fastening nut. .

In addition, the cover 20 may be configured to have a function of preventing glare from light from the light source or diffusing light from the light source to the periphery. The lower flange 25 is provided along the outer circumference of the cover 20 to have a ring (ring) structure. The lower flange 25 is formed in a shape that overlaps with the upper flange 15 when the cover 20 shields the open bottom of the case 10.

1 and 2, but the case 10 is shown to have a rectangular structure, the case 10 may be formed to have a different shape, such as circular, so that the cover 20 also the case 10 It may be changed to the shape corresponding to).

Although the cover 20 is illustrated as being flat in FIG. 2, the shape of the cover 20 is not limited thereto and may be changed into various shapes such as a central area formed in a convex shape downward.

As shown in FIG. 3, the flange holders 30 are covered with the top flange 15 and the cover 20 of the superimposed case 10 as the cover 20 is arranged to shield the open bottom of the case 10. Of the lower flange 25. The flange holders 30 are provided with coupling grooves 35 into which the upper flange 15 and the lower flange 25 are overlapped. According to this, when the upper flange 15 and the lower flange 25 are inserted into the coupling groove 35 of the flange holders 30 in an overlapping state, the upper flange 15 and the lower flange 25 are coupled to the case 10. ) And the cover 20 are coupled to each other.

2 and 3, the flange holders 30 connect one side of the upper member 31 and the lower member 32 and the upper member 31 and the lower member 32 which face each other in the upper and lower sides. The side member 33 is comprised. According to this, the flange holders 30 have an inner space in which the upper side, the lower side, and one side are blocked by the upper member 31, the lower member 32, and the side member 33 as the coupling groove 35.

The flange holders 30 may be made of rubber, metal or synthetic resin. The flange holders 30 are configured to press the upper flange 15 and the lower flange 25 in a superimposed state in which the upper member 31 and the lower member 32 are fitted into the coupling groove 35 by a predetermined force by elastic force. Can be. To this end, the side member 33 may be integral with the upper member 31 and the lower member 32. When the upper flange 15 and the lower flange 25 are elastically pressed when the flange holders 30 are coupled, the upper flange 15 and the lower flange 25 may be coupled with an increased force.

1 and 2, the flange holders 30 are continuously disposed along the circumferential direction of the upper flange 15 and the lower flange 25 in an overlapping state, and the holder fastening means 40 is disposed in this continuous manner. Is configured to fasten adjacent ends of the flange holders 30 adjacent to each other.

The holder fastening means 40 is composed of a first fastening member 41, a second fastening member 42, a fastening screw 43, and the like.

The first fastening member 41 is provided above the end of one of the flange holders 30 adjacent to each other (that is, the upper surface of the upper member 31). The second fastening member 42 is provided to face the first fastening member 41 on an upper side of the other end of the flange holders 30 adjacent to each other (that is, the upper surface of the upper member 31). The fastening screw 43 fastens the first fastening member 41 and the second fastening member 42 that face each other.

For example, the first and second fastening members 41 and 42 are provided with corresponding through holes, respectively, and the fastening screw 43 has corresponding through holes of the first and second fastening members 41 and 42. The first and second fastening members 41 and 42 may be fastened by being coupled with the fastening nut while passing.

As another example, one of the first and second fastening members 41 and 42 is provided with a through hole, the other is provided with a female screw hole corresponding to the through hole, and the fastening screw 43 passes through the through hole. The first and second fastening members 41 and 42 may be fastened by being coupled to the female screw holes in one state.

According to such a holder fastening means 40, the luminaire according to the first embodiment of the present invention, when installed on the ceiling by the flange holders 30 so that the holder fastening means 40 is not visible when viewed from the lower side Since it is concealed, as the fastening screw 43 of the holder fastening means 40 is exposed to the outside as it is, it can prevent that aesthetics are impaired.

Further, when the fastening screw 43 is loosened, the worker can work while looking at the fastening screw 43 from the side, so that the fastening screw 43 can be loosened in a relatively comfortable posture. Of course, the fastening screw 43 may be tightened comfortably.

In addition, the luminaire according to the first embodiment of the present invention, since the case 10 and the cover 20 are coupled by the flange holders 30, the cover 20 in the process of loosening the fastening screw 43 ) Can be prevented from falling off the case (10), thereby fastening the fastening screw 43 by using both hands.
