First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

1 and 2 are perspective views schematically showing the configuration of the ceiling-mounted lighting device according to an embodiment of the present invention, Figure 3 and Figure 4 is a ceiling-mounted lighting according to another embodiment of the present invention 5 is a cross-sectional view schematically showing the internal structure of the device, Figure 5 is a schematic cross-sectional view showing the assembly process of the ceiling-mounted lighting device according to an embodiment of the present invention.

Ceiling recessed lighting apparatus according to an embodiment of the present invention is installed in a manner that is inserted into the opening of the ceiling panel (W), the housing 100 coupled to the opening of the ceiling panel (W), the housing 100 A fixing clip 200 hinged to the housing, a fixing frame 300 inserted into the housing 100, a fixing means 400 fixedly supporting the fixing frame 300, and a lamp mounted to the fixing frame 300. And 500.

As shown in FIG. 1, the housing 100 includes a hollow pipe-shaped guide part 110 inserted into an opening of the ceiling panel W, and a plan extending in a horizontal direction along the circumference of the guide part 110. It is configured to include a branch (120). Since the flange portion 120 extends to protrude outward from the guide portion 110, the flange portion 120 when the guide portion 110 of the housing 100 is inserted into the opening of the ceiling panel W. Is coupled to the outer surface of the ceiling panel W along the perimeter of the opening. At this time, the housing 100 is fixed in such a manner that the fixing clip 200 to be described later is caught on the inner surface of the ceiling panel W and fixedly supported by the ceiling panel W.

Fixing clip 200 is rotatably hinged to the outer surface of the guide portion 110 of the housing 100, as shown in Figs. The hinge shaft 210 with respect to the fixing clip 200 is formed horizontally on the outer surface of the guide portion 110 so that the fixing clip 200 is inward or outward of the guide portion 110 around the hinge shaft 210. Rotatably coupled in a direction. At least two fixing clips 200 may be mounted, and two or more fixing clips 200 may be mounted symmetrically in directions facing each other, as shown in FIGS. 1 and 2, but alternatively, three or four may be provided. In this case, it is preferable that the fixing force for fixing the housing 100 by the position of the fixing clip 200 is arranged to have the same separation distance from each other so that the fixing force can be evenly distributed.

The fixing frame 300 is inserted into the guide part 110 of the housing 100. The lamp 500 which emits light by receiving power is mounted on the fixing frame 300 and the housing 100 via the fixing frame 300. ) Is combined. The fixing frame 300 is fixedly supported in a state of being inserted into the guide portion 110 by a separate fixing means 400.

At this time, in the ceiling-mounted lighting device according to an embodiment of the present invention, as the fixing frame 300 is inserted into the guide portion 110 of the housing 100, the fixing clip 200 is directed outward of the guide portion 110. By rotating and constrained to rotate, the housing 100 is fixedly supported by the ceiling panel (W). In more detail, when the fixing frame 300 is inserted into the guide unit 110, the fixing clip 200 contacts and interferes with the fixing frame 300 to be rotated in the outward direction of the guide unit 110. In the state, the fixed clip 200 is supported by both ends of the fixed frame 300 by the outer surface and the inner surface of the ceiling panel (W) is tightly constrained rotationally. As such, when the fixing clip 200 is rotationally constrained in a state of rotating in the outward direction of the guide part 110, the housing 100 is contacted without being separated from the ceiling panel W by the rotationally restraining fixing clip 200. It is fixed and supported in a state.

Therefore, the ceiling-mounted lighting device according to an embodiment of the present invention inserts the fixing frame 300 to which the lamp 500 is simply coupled to the guide unit 110 of the housing 100 without a separate bolt coupling or tool. By operation, the entire lighting device including the housing 100 is coupled to the wall surface of the ceiling panel W.

At this time, the fixing clip 200 is preferably formed to be bent so that some section is formed to protrude further in the inner direction than the inner surface of the guide portion 110 in the complete rotation in the outer direction of the guide portion 110. That is, the mechanism in which the housing 100 is fixedly supported on the ceiling panel W by the fixing clip 200 is as described above and the fixing clip 200 is supported by the inner surface of the ceiling panel W and is rotationally constrained. This is because, at this time, to transmit the rotational constraint force to the fixing clip 200 is a fixed frame 300 is inserted into the guide portion (110). Therefore, in order for the fixing clip 200 to receive the rotation restraining force by the fixing frame 300 in the state in which the fixing frame 300 is inserted, the fixing clip 200 must contact and interfere with the outer surface of the fixing frame 300. In a state in which the fixing clip 200 is completely rotated in the outward direction of the guide part 110, at least some sections may be formed to protrude more than the inner surface of the guide part 110. Therefore, the cutout 111 may be formed at one end of the guide part 110 such that the fixing clip 200 may protrude more than the inner surface of the guide part 110.

On the contrary, even if the fixing clip 200 does not contact the outer surface of the fixing frame 300 in the state where the fixing clip 200 is rotated in the outward direction of the guide unit 110, even if the fixing frame 300 is inserted into the guide unit 110. Since the fixing clip 200 is not rotationally restrained, the housing 100 is separated downward from the ceiling panel W by its own weight. However, even in this case, since the fixing clip 200 coupled to the housing 100 interferes with the inner surface of the ceiling panel W and rotates in the inner direction of the guide part 110 while the housing 100 moves downward. When the housing 100 is separated downward by a certain distance, the fixing clip 200 is interfering with the outer surface of the fixing frame 300 to be rotationally constrained as described above. Therefore, even in this case, the housing 100 does not escape downward more than a certain distance. By adjusting the bending shape of the fixing clip 200 according to this structure, the downward departure distance of the housing 100 may be adjusted.

Since the fixing clip 200 is supported by the outer surface of the fixing frame 300 and the inner surface of the ceiling panel W in this way and is rotationally constrained, it is preferable that the fixing clip 200 is formed of an elastic material so as to be elastically deformed and elastically supported. By being formed of such an elastic material, it can have a wider application range for the size and shape associated with the support structure, such as the thickness of the ceiling panel (W) or the dimensions of the fixing frame (300).

On the other hand, the fixing frame 300 for rotationally restraining and supporting the fixing clip 200, the outer surface in contact with the inner surface of the guide portion 110 corresponding to the shape of the guide portion 110 as shown in FIG. It is preferably formed in the shape of a hollow pipe. Therefore, the fixing frame 300 can maintain a more stable fixed state in the state inserted into the guide portion 110, in particular, even when in close contact with the fixing clip 200 does not shake or loosen more solid coupling state I can keep it.

In addition, the fixing frame 300 according to an embodiment of the present invention is preferably formed in a hollow pipe shape as described above, in which the downward one side may be formed in a shape that is closed by the base plate 310. The lamp 500 is mounted to the base plate 310 to perform an illumination function. At this time, the lamp 500 may be used a variety of lamps, such as incandescent bulbs, bulb-type fluorescent lamps of the filament structure, LED lamp 500 is preferably used. The LED lamp 500 may be formed in a form in which a plurality of LEDs 520 are coupled to the LED receiving plate 510, wherein the LED lamp 500 is the LED receiving plate 510 through the coupling bolt (S). It may be coupled to the fixed frame 300 in a manner that is coupled to the base plate 310 of the fixed frame 300. In addition, the base plate 310 may be equipped with a lamp cover 600 surrounding the lamp 500 at the bottom, a detailed description of the mounting structure of the lamp cover 600 will be described later.

As described above, the fixing frame 300 having the downward one side closed by the base plate 310 is opened upward at one side, and as shown in FIGS. 1 to 3, the upper side is fixed to the lamp 500. A separate cover plate 320 may be coupled so that the power supply 700 for supplying power may be mounted through the coupling bolt S. However, the power supply device 700 may be seated in the inner space of the fixing frame 300 without being mounted on the cover plate 320, in which case a separate cover plate 320 is unnecessary and the fixing frame 300 is not mounted. One side upward of the can be kept open.

Since the fixing frame 300 according to an embodiment of the present invention is formed to have a relatively large area in the form of a hollow pipe having one surface open as described above, the fixing frame 300 has a structure in which a heat dissipation function is performed by the fixing frame 300 itself. That is, in a general ceiling recessed lighting device, since the fixing frame for fixing the lamp cannot exhibit heat dissipation in its structure, a large amount of heat is generated by the operation of the lamp inside the housing. Doing so may cause the lamp to malfunction or fail. However, the fixing frame 300 according to an embodiment of the present invention is formed in the shape of a hollow pipe with an upper surface open and protrudes upwardly from the housing 100, and its total area is relatively large. Therefore, the fixed frame 300 self-heating function is excellent structure.

In other words, when heat is generated by the operation of the lamp 500 mounted on the base plate 310, the heat is transferred to the base plate 310 and then uniformly transmitted throughout the fixing frame 300. Since the fixed frame 300 has a large area in the form of a hollow pipe and protrudes upward from the housing 100, the area exposed to air is relatively increased, thereby improving self-heating function. Meanwhile, a plurality of heat dissipation holes 301 may be formed at the upper end of the fixing frame 300 in order to improve the heat dissipation function in the fixing frame 300 according to the exemplary embodiment of the present invention. .

Next, referring to the structure of the fixing means 400 for holding and fixing the fixing frame 300, the fixing means 400 is one side of the fixing clip 200 as shown in FIG. 3 according to an embodiment of the present invention. The fixing protrusion 410 is formed to protrude in the inner direction of the guide portion 110, and the fixing projection 410 is configured to include a fixing hole 420 formed on the side of the fixing frame 300 to be engaged and engaged do. When the fixing frame 300 is inserted into the guide part 110 of the housing 100 according to the structure, the fixing clip 200 is in contact with the outer end of the fixing frame 300 and interferes with the guide part 110. When the fixing frame 300 continues to be inserted in this state, the fixing protrusion 300 of the fixing clip 200 is fixed at the time when the fixing frame 300 is inserted. It is inserted into the fixing hole 420 of the engagement. As the fixing protrusion 410 and the fixing hole 420 are engaged with each other, the fixing frame 300 is supported by the fixing protrusion 410. Accordingly, the fixing clip 200 serves to support the fixing frame 300 by the fixing protrusion 410 and at the same time, the end of the fixing clip 200 is interfering with the inner surface of the ceiling panel W so that the entire apparatus including the housing 100 is provided. Play a supporting role.

Therefore, the fixing rod 430 moves upward along the vertical slot portion 441 while the fixing frame 300 is inserted into the guide unit 110, and the fixing frame 300 is inserted into the guide unit 110. Since the fixing rod 430 is located at the top of the vertical slot portion 441 in the completed state, when the fixing frame 300 is rotated about the vertical axis in this state, the fixing rod 430 is the horizontal slot portion 442. Will move along. When the fixed rod 430 is inserted and seated in the horizontal slot portion 442 as described above, the fixed frame 300 is prevented from moving downward by its own weight and is supported by being seated in the coupled state of the housing 100. In this case, in the case of releasing the fixing means 400, the fixing frame 300 may be rotated in the opposite direction, and then the fixing rod 430 may be separated to be separated from the outside along the vertical slot portion 441.

The fixing means 400 described above is illustrated according to an embodiment of the present invention, and in addition to the above, the fixing means 400 may be modified in various ways through various link devices or elastic protrusions.
