Description

The field of technology.

The invention relates to the field of lighting, and in particular to lighting devices using semiconductor light sources used to install Grilyato suspended ceilings in cells (cells) and the like.

The level of technology.

There are three known types of solutions for LED lamps for installation in cells of suspended ceilings: office lamps for installation in suspended ceilings, mainly Armstrong; recessed luminaires for false ceilings; recessed spotlights for false ceilings

Analogs of LED lamps are known (patent RU 122820 U1, IPC H05K 5/00, 06/15/2012; patent RU 115441 U1, IPC F21S 4/00, 11/21/2011; patent RU 109609 U1, IPC H01L 33/00, dated 24.06 .2011; patent RU 103233 U1, IPC H01L 33/00, dated 09/12/2010; patent RU 103387 U1, IPC F21S 8/00, 11/24/2010) relating to the first form. Their disadvantage is that they are focused on installation in Armstrong suspended ceilings, for installation in other suspended ceilings (including Grilyato), the latter must provide special niches (cutouts) for lamps.

Known analogues of LED lamps (US 2013/0050994 A1, IPC F21V 7/00, 02/28/2011; patent RU 123229 U1, IPC H01L 33/00, 03/15/2012; patent RU 122802 U1, IPC H01L 33/00, from 03/15/2012; patent RU 120481 U1, IPC F21S 8/00, dated March 15, 2012; patent RU 119850 U1, IPC F21S 13/00, 03/15/2012; patent RU 119849 U1, IPC F21S 8/00, dated 03.15. 2012) for the installation of which special seats have already been provided for in the suspended ceilings by the manufacturer of the ceilings, or transitional structures and systems are used (for example, patent US 7784979 B2, IPC F21V 7/00, F21V 15/00, F21S 8/00 of 08/31/2010; US 2013/0027915 A1, IPC F21S 8/04, H05K 13/00, F16M 13/00, F21V 29/00 dated 01/31/2013), or seats Execute forces installers. These analogues are also not suitable for installation in suspended ceilings Grilyato and the like.

Known analogues of LED spotlights including and with built-in fastening means: (application RU 2009139439 A, IPC F21V 21/00 dated 10.26.2009; US 20130016505 A1, IPC F21V 13/08, F21V 9/00, F21S 2/005 with priority date 04/09/2010); including providing for installation also in a cartridge from traditional light sources (EP 2083210 (A1), IPC F21K 7/00 of 07/29/2009) as well as additional transitional designs for spotlights (EP 2466198 (A1) IPC F21S 8/00; F21S 8 / 02; F21V 15/01; F21V 19/00; F21 V29 / 00; F21Y 101/02 of 06/20/2012). These solutions are suitable for use in smaller cells of suspended ceilings (with a size of 40 mm or more), in which case there is no need to make cutouts in the ceiling sections. Nevertheless, the installation of additional lighting fixtures is necessary. In addition, the luminous flux per unit of a spotlight is not large (which requires the installation of a sufficiently large number of points), limited by the heat-dissipating capabilities of the fixtures.

For the prototype of the claimed invention, a decision was made according to patent RU 119850 U1, IPC F21S 13/00, dated 03.15.2012.

The technical task of the present invention is the creation of a lighting device adapted for installation in suspended ceilings of Grilyato and the like, excluding any modifications to the structures of the suspended ceiling, the installation of which involves operations only by inserting the lamp into the cell and connecting the power supply (if necessary, it can be mounted on a suspension (existing or separate)). In this case, the lighting device can easily be moved to another place (restriction only on the length of the wire) according to the required lighting situation. In addition, the lighting device should create a greater luminous flux compared to spotlights. In addition, the lighting device should have the smallest possible mass in order to both reduce the material consumption of the product and reduce the number of ceiling suspension points.

SUMMARY OF THE INVENTION

The essence of the claimed group of inventions is that:

- firstly, the design of the lighting device allows it to be installed in suspended ceilings with cells (cells) ranging in size from 40 × 40 mm to 250 × 250 mm and a thickness of partitions from 1 to 30 mm (the distance between adjacent cells) with a vertical U-shaped ( or another) profile without the use of operations to prepare niches for fixtures (special cutouts) i.e. without disturbing the design of the false ceiling. The lamp is installed in existing cells;

- secondly, the design of the lighting device allows you to change its location in a suspended ceiling with cells ranging in size from 40 × 40 mm to 250 × 250 mm and a thickness of partitions from 1 to 30 mm with a vertical U-shaped (or other) profile without using operations dismantling of suspended ceiling structures. The lamp is installed in any place where the power cord reaches. This is especially valuable when changing the layout and layout of the lighted room (for example, moving window displays, shelving in shopping centers, etc.), in this case, the lamps move to the right place (the right cell) according to the desired situation of the lighted area. Thus, the costs of both the installation of lamps and the reconstruction of the lighting system are significantly reduced;

- the removal of sections of the cooling radiator of the device beyond the size of the light module increases its efficiency, since they are located above empty cells (the best conditions for convective heat transfer). This also allows to reduce the mass of the body;

- execution of the luminaire housing made of aluminum alloy, with the dimensions of the light module compartment smaller or equal (with a smaller tolerance) to the cell size, significantly reduces the weight of the product (compared to built-in solutions, for example, office lamps 600 × 600 from 10 to 15 times for which require at least three independent suspension points). This allows you to install devices near the fixtures of the suspended ceiling, without their own fastening (suspension), since the structure of the suspended ceiling is not bearing;

- for the suspension of the device, only one central node or two opposite peripheral ones is sufficient, while for an office lamp at least three are needed for balancing. The device is balanced by the design of the false ceiling. As a result, the complexity of the installation of the device is reduced by eliminating the organization of additional suspension points;

- a smaller height of the compartment of the light part in comparison with the height of the profile of the suspended ceiling leads to the fact that the device is recessed relative to the cell, thus meeting the requirements for the protective angle of the light device.

The technical result is a reduction in the complexity of mounting the lighting system in the suspended ceilings of Grillato and the like, reconstruction of the lighting system, increasing the luminous flux per unit area of the suspended ceiling.

Achieved by the following layout of the lamp:

The luminaire consists of a radiator case (hereinafter in the description, for brevity, the case) 1, a light module 5, a plafond 2, a power source (at least one depends on the required operational characteristics). The housing 1 is made in the form of a ribbed (needle or wavy) radiator with vertically blown fins (with at least one) with a compartment of the light module 1-1 in the central part, which repeats the contour of the ceiling cell. A shade 2 is attached to compartment 1-1, also repeating the contour of the cell. The radiator is spread to neighboring empty cells. At the same time, the design of the lamp allows you to push the lamp into the cell of the suspended ceiling. To regulate the luminous flux obtained from one product, it is also possible that the radiator does not go beyond the unit cell (in this case, the luminous flux is minimal) or, on the contrary, occupies adjacent cells in the orthogonal direction (it is possible to increase the luminous flux, however, when This loses the advantage of installing the lamp in the already assembled suspended ceiling, i.e. the lamp can no longer be inserted into the cell of the suspended ceiling).

The design of the radiator provides nodes 1-6 for mounting the power source. In this case, two opposite holes 1-4 on the sides of the radiator are used to suspend the device. In addition, other versions of the mounting points of the power source on the lamp housing are possible. Otherwise, if the power source is located directly on the suspension cable (either a lamp or exclusively a power source) by using a U-shaped bracket, the attachment point 1-3 is placed in the center on the back side of the light module compartment 1-1 for hanging the device itself. To eliminate the breakage of the power supply wire, the latter is threaded through the hole 1-5 provided on the end of the radiator sections.

The housing 1 of the lamp can be completely located above the cell of the suspended ceiling, or partially embedded in the cell, while the "shoulders" of the radiator of the housing are located above the cells, including neighboring ones. In addition, the housing may be within the dimensions of the cell (cage) of the ceiling in which it is installed, in this case the radiator of the housing is also located within the dimensions of this cell.

The housing 1 can be made of aluminum alloy by casting (i.e., the housing is a non-separable solid cast part); by extrusion from an aluminum alloy (in this case, the central compartment of the light module is realized by the light module itself, or an aluminum alloy compartment is mounted as an additional part, i.e. the housing is collapsible, consists of a radiator and a compartment of the light module). The housing may contain several compartments of light modules. The housing may have several openings for the input of the power cable, including when several power compartments are used. The housing provides structural elements for grounding (in some cases of grounding) the light device. Structural elements that realize at least one point of suspension of the lamp, which is used both for independent suspension and suspension for the construction of a suspended ceiling, are also provided in the housing of the light fixture.

The lampshade can be made of a transparent (translucent, opaque) material and (or) scattering and have a complex geometric shape that follows (not repeating) the contours of the cell (cage) of the suspended ceiling. Moreover, it can be flat, concave or convex. The ceiling is mounted to the radiator case by means of bushings (cylindrical, rectangular, polygonal, as well as combined with screws). The ceiling and (or) its front part can be located both inside the vertical and horizontal dimensions of the cell (cage) of the suspended ceiling and beyond.

The power supply of the lamp is provided in the ranges from 0.7 to 42 volts and from 42 to 1000 volts of constant, alternating, rectified, pulsating, as well as a complex current shape.

The light module of the lamp has at least one solid-state semiconductor light source, including one made on chip-onboard technology (a chip on a board). If the light sources are monochrome, the inner surface of the lampshade is covered with a phosphor. The light module is fastened with self-tapping screws, screws, heat-conducting adhesive, heat-conducting adhesive tape. The light module may or may not repeat the outline of the compartment of the light module.

The lamp can both rise and not rise (to be nested) in the cells of the suspended ceiling.

The weight of the complete lamp, including the power source, is not more than 0.7 kg.

The implementation of the invention.

The lighting device is as follows:

A lamp is inserted into the cell of the suspended ceiling 4 and installed in such a way that the compartment of the light module 1-1 with the ceiling 2 is recessed in the cell (the ceiling can protrude from the cell). The lamp is installed near the suspension point of the suspended ceiling structures 4, either on an independent suspension through the central suspension unit 1-3 (when attaching the power source to the suspension itself, placing the power source separately from the lamp) or by using the opposite holes 1-4 (when placing the power source on the housing 1 of the lamp). The luminaire balances on the cell profile. The power cable is passed through the hole 1-5 in the end of the radiator (to avoid breakage when moving the lamp to other cells), and the cable wires are mounted in the terminals of the power source. When a voltage is applied, the light module 5 begins to emit a light flux; the heat generated in this case is dissipated by the fins of the radiator 1-2, purged due to the best convection conditions over empty cells. Since the light module is "recessed" in the cell, this allows you to fulfill the requirements for the protective angle of the light device. Grounding the lamp is carried out on the structural element 1-8. The plafond is attached to the lamp housing by means of fasteners 3.
