The present invention relates to a cushioning structure for a ceiling lighting fixture and a method of constructing a lighting fixture using the same. More specifically, the present invention relates to a cushioning structure for a ceiling lighting fixture, and more specifically, to suppress noise generated from the lighting fixture due to vibration transmitted to the lighting fixture through the ceiling, thereby reducing discomfort to household members. This relates to a cushioning structure for ceiling lighting fixtures that prevents discomfort and a method of constructing lighting fixtures using the same.

In general, multi-unit housing such as apartments or multi-family houses is composed of a wall structure in which columns made of reinforced concrete with a certain thickness and slabs supported by walls are connected to form one structure. In other words, foundation work is completed by constructing slabs supported by columns and walls according to the number of floors of the building, and then laying out pipes such as heating pipes and water supply pipes at regular intervals on the concrete slab, and then constructing cement mortar to a certain thickness. It is done.

Such architectural structures have a certain degree of blocking performance against airborne sounds caused by conversations or TV, but since the floor that divides each floor, that is, the slab, is constructed only with concrete, noise or shock generated inside the corresponding floor of the building is reduced. There was a problem in that the vibrations caused by this were easily transmitted to adjacent households and lower floors through the inter-floor slabs.

In households experiencing such noise between floors, noise is usually heard from the ceiling. As a conventional technology to solve this problem, "Interfloor noise prevention ceiling panel and its construction method" in Korean Patent Publication No. 10-2013-0005427 has been proposed, which is An embedded insert is formed on the upper part of the main body, a piping groove is formed on the bottom, and a coupling means for continuous connection is formed around the circumference.

The primary vibration isolator 120 may be made separately from the lighting case 130, but is not limited to this, and has a planar structure corresponding to the planar structure of the lighting case 130, and is pre-attached to the upper surface of the lighting case 130. It can be prepared as much as possible. In addition, the primary vibration isolator 120 may be formed with a plurality of through holes 121 so that the fastening bolts 150 for screwing into the fastening holes 111 of the fixing metal 110 pass through.

The lighting case 130 is located below the primary vibration isolator 120, so that it is fixed to the fixture 110 with the primary vibration isolator 120 in between, and a lighting device 132 for irradiating light downward is provided. It can be provided. The lighting case 130 may have a lighting device 132 installed in a receiving space 131 that opens downward, and a fastening bolt 150 for screwing into the fastening hole 111 of the fixing bracket 110 penetrates. A plurality of through holes 133 may be formed to do so.

The lighting fixture 132 includes a lamp made of an LED, a fluorescent lamp, or a light bulb to emit light, a power supply unit that converts and supplies power supplied from the outside as needed for the operation of the lamp, and performs control necessary for the operation of the lamp. It may include a PCB, etc. for this purpose.

The diffusion cover 140 is fixed to the lower side of the lighting case 130 and may have a light diffusion unit 141 that transmits and diffuses light. The light diffusion unit 141 may be made of a light-transmissive material for transmitting light. The diffusion cover 140 may be formed with a plurality of through holes 142 so that the fastening bolts 150 for screwing into the fastening holes 111 of the fixing metal 110 pass through.

A secondary vibration isolator 160 may be interposed between the lighting case 130 and the diffusion cover 140 to absorb vibration.

The secondary dustproof material 160 may be made of, for example, rubber, silicone, sponge, urethane, or other foam materials, as well as a pad or dustproof tape made of a dustproof material. The secondary dustproof material 160 may be made separately from the lighting case 130 or the diffusion cover 140, but is not limited to this and has a planar structure corresponding to the planar structure of the lighting case 130 or the diffusion cover 140. It can be provided to be attached to the lower surface of the lighting case 130 or the upper surface of the diffusion cover 140. In addition, the secondary vibration isolator 160 may be formed with a plurality of through holes 162 so that the fastening bolts 150 for screwing into the fastening holes 111 of the fixing metal 110 pass through.

Referring to FIG. 4, the secondary vibration isolator 160 has buffering protrusions 161 on the upper and lower sides in contact with the lighting case 130 and the diffusion cover 140, respectively, in the longitudinal and width directions, as in the present embodiment. Each can be formed to be distributed in large numbers. Therefore, the secondary vibration isolator 160 allows the vibration applied from the lighting case 130 to be transmitted through each of the buffer protrusions 161 and dispersed over the entire area, thereby blocking the vibration propagation toward the diffusion cover 140. It is possible to fundamentally block noise caused by clearance between the lighting case 130 and the diffusion cover 140.

The primary and secondary vibration isolators 120 and 160 have a thickness of 1 to 3 mm and a width of 10 to 30 mm, and may be made of foam rubber such as PE or EVA.

It can be fastened to the fastening hole 111 of the fixing bracket 110, but is not limited to this and various fixing methods can be used.

As shown in Figure 5, the secondary vibration isolator 260 is another example, the upper and lower sides in contact with the lighting case 130 (see Figures 1 to 3) and the diffusion cover 140 (see Figures 1 to 3), respectively. Each of the vibration dispersing protrusions 261 may be formed to be distributed in large numbers.

A plurality of vibration dispersing protrusions 261 may be formed on each of the upper and lower sides in a zigzag manner along the longitudinal direction, and are positioned from one side facing each other to the side of the secondary vibration isolator 260. It is formed so that the height increases to the other side, so that a small part 261a on one side and a dense part 261b on the other side are formed, so that when compressed, the dense part 261b has a relatively higher density than the small part 261a. The vibration dispersing protrusions 261 located on the upper side and the vibration dispersing protrusions 261 located on the lower side may be formed to be zigzagly arranged with each other. For this reason, when a compressive force is applied downward (a direction, b direction) to the small part 261a and the dense part 261b of the secondary vibration isolator 260, the small part 261a and the dense part 261b in the horizontal direction ) Due to the difference in density, the vertical vibration can be converted to be transmitted horizontally and distributed over the entire area, and the zigzag arrangement in the horizontal and vertical directions increases the vibration transmission path to help with shock dispersion. It can be maintained in a seated state between the lighting case (130; see Figures 1 to 3) and the diffusion cover (140; see Figures 1 to 3) by the force that expands in both directions (c direction) when compressed. can help
