Description

The invention relates to lighting, and in particular to parts of lighting devices used in construction for interior decoration using stretch ceilings, for example, from polyvinyl chloride.

Closest to the technical nature of the present invention is the selected lighting fixture of stretch ceiling fixtures selected as a prototype, comprising a lamp housing with a socket for accommodating a light source and a washer connected to the housing by detachable connection with a layer of adhesive material intended for gluing to the canvas ceiling tension ( Eurasian patent No. 005061, published on October 28, 2004).

The disadvantages of the prototype are the low operational capabilities of the lighting fixtures due to the excessive complexity of installation and reduced strength of the stretch ceiling web due to the need to cut out part of the web along the inner contour of the mounting plate; due to the inability to hold water in the event of emergency leaks, since there are sufficient gaps between the light source, the lamp housing and the inner hole of the mounting plate for water to enter, as a result there is an increased risk of short circuit; due to the risk of damage to the fabric of the stretch ceiling when cutting holes in the fabric, which requires the installer to be careful and skill to perform this operation; due to the low ergonomics of the operation of the lamp, since with any replacement of the light source, the electrical connector with electric wires goes beyond the invisible zone of the inter-ceiling space, which is a sign of insufficient constructive study of the product; due to the decrease in the height of the stretch ceiling of the room due to the fact that part of the design of the lamp is located in the inter-ceiling space.

The technical result achieved by the present invention is to expand the functionality by simultaneously installing the lamp and ensuring the tightness of the stretch ceiling, to expand technological capabilities by simultaneously gluing the lighting fixtures to the canvas of the stretch ceiling and piercing it to pass the electric wires of the lamp, as well as expanding the operational capabilities by increasing the ergonomics of the operation of the lamp and increasing the strength otna by eliminating the need to cut the web portion of the inner contour of the fastening washers, and eliminate the risk of damaging it.

The technical result is achieved by the fact that in the lighting fixtures of the ceilings, containing the lamp housing with a socket for placing the light source and connected to the housing by detachably connecting a mounting washer with a layer of adhesive material designed to be glued to the canvas of the stretch ceiling at the end of the mounting washer with at least one tenon with a sharp edge on its top for puncture the stretch ceiling web and with a through a hole in his body for passing at least one electric wire of the lamp from the inter-ceiling space into the cavity of the lamp housing, while the height H1 of the tenon is chosen to be greater than or equal to the thickness h of the web of the stretch ceiling and less than or equal to the height H of the inter-ceiling space.

Lighting fixtures of stretch ceiling fixtures includes a lamp housing 1 with a socket for accommodating a light source (not shown in the figures) and connected to the housing 1 via a detachable connection made, for example, in the form of a latch 2, interacting with the hole 3 in the housing 1, a mounting washer 4 with a layer 5 of adhesive material intended for gluing to the web 6 of a stretch ceiling. At the end of the mounting washer 4 from the side of applying the adhesive layer 5, at least one tenon 7 with a sharp edge 8 at its apex (four tenons is shown in FIG. 2) is punctured to puncture the web 6 of the stretch ceiling and with a through hole 9 in it a body for passing at least one electric wire 10 of the luminaire (FIG. 4 shows two electric wires 10) from the inter-ceiling space 11 into the cavity 12 of the luminaire body 1, while the height H1 of the spike 7 is chosen to be greater than or equal to the thickness h of the canvas 6 of the stretch ceiling and less or equal height H inter ceiling space 11, i.e. h≤H1≤H. The housing 1 of the lamp can be closed with a decorative casing 13. The inner space of the spike 7, through the through hole 9 of which the electric wires 10 are passed, can be filled with composite material 14, for example, in the form of a sealant. In addition, the housing 1 of the lamp and the mounting plate 4 can be made of plastic.

Lighting fixtures of suspended ceilings works as follows.

In the required place of the stretch ceiling web 6 by piercing with the spikes 7, a mounting washer 4 is pre-lubricated with the adhesive material layer 5. To facilitate the passage of the studs 7 through the stretch ceiling web 6, preliminary punctures can be made, for example, using an awl. The surface of the mounting washer 2 is pressed tightly to the surface of the web 6, and simultaneously the spikes (tenon) 7 pass through the web 6. At the same time, two technological operations are combined - piercing and gluing. After the adhesive material has fixed the fixing washer 4, electric wires 10 are passed through the through holes 9, which are connected to the socket (not shown in the figures) of the lamp housing 1, after which the excess of electric wires 10 is removed into the ceiling space 11 or into the voids of the lamp housing 1. Using a detachable connection, the housing 1 of the lamp snaps onto the mounting washer 4. The detachable connection is as follows. The housing 1 of the lamp moves upward in the axial direction towards the web 6 until then, until the latches 2 of the mounting washer 4 come into contact with the corresponding holes 3 of the housing 1 of the lamp (see figure 5). Next, the web is stretched 6. During the installation, the electrical wires 10 are connected to the external electrical wiring (not shown in the figures). Then, the decorative housing 13 is installed using, for example, several latches (not shown in the figures), and a light source (lamp) is inserted into the socket of the housing 1 of the lamp. The stretch ceiling with installed lights is ready for use. The proposed device lighting fixtures allows during operation to change without dismantling the canvas 6 stretch ceiling as a lamp and a decorative housing 13, and the housing 1 of the lamp, if there is a need to use another lamp.

Since the punctured web 6 stretch ceiling is carried out on a very small surface bounded by the surface of the spike 7, and the torn edges of the web 6 are automatically glued with adhesive material previously applied to the mounting washer 4, while gluing - piercing the mounting washer 4 to the fabric 6, that is, for one technological operation, the loss of the bearing capacity of such a web 6 is practically absent, i.e. the strength properties of the web 6 of the stretch ceiling with the lamp practically do not differ from the strength characteristics of the whole web. In addition, the spike 7 allows you to more accurately position the position of the lamp on the surface of the canvas 6 stretch ceiling, which is especially important for decorative and artistic ceilings.

In case it is necessary to completely seal, i.e. to exclude, in emergency situations, the ingress, for example, of water outside the web 6, primarily on the electrical contacts of electrical connectors (not shown in the figures), then the through holes 9 in the spikes 7 are completely closed (filled) with some kind of composite material 14. The indicated property is of particular importance for medical institutions, in the premises of which stretch ceilings made of expensive special antiseptic materials have “weaknesses” in microbiological protection in the form of passages (holes) for the illuminator Nogo equipment.
