Description

FIELD OF THE INVENTION

The invention relates to the field of improving the acoustic conditions of premises for various purposes.

The level of technology.

Today it is known about an acoustic panel with lighting properties (RU 2015101507 A, publ. 06/17/2013), which finds its application mainly in office premises and is a dividing wall with sound-absorbing or sound-blocking properties. An acoustic panel with lighting properties consists of a rigid base plane, which provides mechanical stability, and sound-absorbing material, which contains extended hollow slots in which the light source is placed. This invention solves two problems. Firstly, the provision of soundproofing of workplaces in the office space, due to the use in the design of materials with sound-absorbing or sound-blocking properties. Secondly, the light, which can be blocked by the applied acoustic panel, is compensated by the integrated, essentially flareless illumination and soft illumination of the walls.

It is also known about the light-emitting panel with a transparent mesh supporting panel (RU 2608805 C2, publ. 24.01.2017), which finds its application in office premises. This light emitting panel comprises a first panel optically transparent sheet, a second panel sheet and a cellular supporting panel that contains optically transparent wall cells forming a plurality of tubular channels extending from the first panel sheet in the direction of the second panel sheet. On the panel channels there is a two-dimensional array of light sources, each of which is configured to radiate light into at least one of the tubular channels of the mesh support panel.

A distinctive feature of the sound-diffusing design equipped with a light source is its focus not on isolation or absorption of sound, but on the dispersion of sound waves, thereby creating the best acoustic conditions in the room for listening to music, watching videos, etc. A design feature of the present invention is that the main surface reflecting sound waves is made of optically transparent material that transmits light from a light source.

Samples of the present invention can be used in rooms for various purposes: rooms for viewing video materials, for listening to audio recordings, for recording audio files, shops, catering establishments, theaters, concert halls, office and residential premises, etc.

Disclosure of invention

The present invention solves two problems. Firstly, the use of sound-diffusing structures equipped with a light source will allow you to adjust the acoustic characteristics of rooms for various purposes due to the dispersion of sound in a wide frequency range. Secondly, to create the desired level of illumination in the room. Depending on the number of applied samples of the present invention, this may be additional, evening or main lighting of the premises. Also, with a certain location in the room, the samples of the present invention can be used to illuminate the selected areas of the room - a working area, a relaxation area, a home appliances area, etc.

The technical result of the present invention is the creation of specific conditions that meet the requirements of the user in terms of acoustic characteristics and illumination of the room, due to the use of the necessary number of sound-diffusing structures equipped with a light source.

Various leisure options are very popular today - visiting theaters, cinemas, concert halls, bars, restaurants, watching video files and listening to audio files at home. An integral part of this pastime is sound. At the same time, sound quality has a significant impact on the positive emotions that a person can experience. The existing sound-diffusing structures that improve the acoustic properties of a room have a significant drawback - they block light, reducing the level of illumination of rooms. A sound diffusing structure equipped with a light source will compensate for this drawback with the help of an integrated light source in the sound diffusing structure. The use of samples of the present invention in rooms in which there is no natural lighting (cinema, theater, concert halls, etc.) will reduce the cost of creating artificial lighting, as well as provide additional opportunities for creating the design of the room.

Design features of the present invention allow the use of samples in rooms for various purposes on different surfaces (walls, floors, ceilings). Also, a sound diffusing structure equipped with a light source can be mounted on a mobile structure, which will allow it to be placed for use only if necessary.

The effect on the acoustic properties of the room depends on the dimensions of the sound-diffusing structure equipped with a light source, and is determined by the number, width and depth of the front panels, as well as the total number of sound-diffusing structures equipped with a light source in the room.

The invention is illustrated by drawings. In FIG. 1 is a front view of the present invention. The sound diffusing structure, equipped with a light source, is a parallelepiped-shaped structure. Four of the six faces of the box are represented by the side walls (1) - upper, lower, right and left. The side walls (1) are made of sheet materials, such as plywood, fiberboard, chipboard, etc. The front and rear faces of the box are absent, or can be represented in front by acoustic fabric and rear by the back cover, respectively.

Acoustic fabric is a translucent material, the main feature of which is the ability not to affect the propagation of sound waves in a wide range of frequencies, i.e. Do not weaken their characteristics and do not distort the direction. The acoustic fabric is made from polyester or polyolefin. The creation of a material with the indicated properties is achieved due to the special capture of the threads. The main task of acoustic tissue is to perform decorative functions, without affecting the propagation of sound waves.

Between the right and left side walls (1) and / or the upper and lower side walls (1) are parallel ribs (2). The ribs (2) can be made of the same materials as the side walls (1). Between the four surfaces, which are ribs (2) or ribs (2) and side walls (1), front panels (3) are located. Front panels (3) are made of optically transparent material. The term "optically transparent material" should be understood as natural and synthetic materials that completely or partially transmit light. The number of front panels (3) must be at least three, while at least one third of the front panels (3) must be located at an excellent distance relative to the front face of the box. Behind the front panels (3) is the light source (4). An incandescent lamp, gas discharge lamp, LED lamp, etc. can act as a light source (4).

In FIG. 2 and FIG. 3 shows front and rear views, respectively, of an embodiment of a sound diffusing structure equipped with a light source. A sound diffusing structure equipped with a light source is a rectangular parallelepiped structure with sides of 596 × 596 × 221 mm. Four of the six faces of the parallelepiped are represented by side walls (1) made of plywood 8 mm thick. The front face of the parallelepiped is absent, and the back is a rear cover made of plywood 8 mm thick (9). In the back cover (9) there are four holes for mounting on the wall (10) and four holes for mounting the back cover (11) with bolts (12). The presence of four holes for mounting on the wall (10) allows you to mount a sound-diffusing structure equipped with a light source on the wall both in the indicated position and with a rotation of 90, 180, 270 degrees relative to it. This feature allows you to orient in the necessary way the placement of sound-diffusing structures equipped with a light source, creating an individual room design. Between the right and left side walls (1) are parallel ribs (2) in the amount of six pieces, made of plywood with a thickness of 8 mm. Between the side walls (1) and the ribs (2) there are 14 cubic supports (5) of various sizes made of a bar and seven front panels (3) fixed in them made of frosted glass measuring 496 × 76 × 4 mm. The first, second, third and seventh front panels (3) are located at an excellent distance relative to the front face of the box. Behind the front panels (3) there are 14 light sources (4), which are segments of the LED strip mounted on each of the cubic supports (5). On the first, seventh, eighth and fourteenth cubic supports (5), metal plates (15) fixed in them with self-tapping screws (17) are located. Threaded nuts (16) are installed on metal plates (15) for fastening the back cover (9) with bolts (12), as well as an opening for mounting a sound-diffusing structure equipped with a light source on the wall using a recess (18) in a cubic support (5) ) Between the third and tenth cubic supports (5), there is a Din rail (6) made of galvanized steel, on which a zero bus (7) and a power source (8) are fixed. The power source is connected to an alternating current network with a voltage of 220 V using a 220 V cable (13). The direct current created by the power supply with a voltage of 12 V is supplied to the zero bus (7), to which all light sources (4) are connected using a 12 V cable (14).
