Description

Lighting combined use speaker {AN ILLUMINATION COMBINED USE SCHILLING SPEAKER}

The present invention is to be installed on the ceiling in a spacious room, such as a lecture room or a conference room, a plurality of LED light emitting body is equipped with a speaker in a housing consisting of a single body in a combined lighting speaker that can simultaneously exhibit the speaker function and lighting function It is about.

In indoor spaces such as lecture rooms and conference rooms, lighting fixtures such as fluorescent lamps are installed on the ceiling for indoor lighting. There are various kinds of lighting fixtures according to their structure or form, but they are generally installed by installing them on the ceiling.

On the other hand, in addition to the above-described lighting fixtures, ceiling speakers are also installed on the ceiling, and since the lighting fixtures and the speaker installation work are separately performed according to the building plan, a construction cost is required accordingly, and the lighting fixtures are first installed. In this case, it was necessary to install the sealing speaker at the place different from the location, and it was inconvenient for the wiring work to install the speaker without affecting the wiring of the lighting fixture.

In addition, when the lighting fixture is already installed on the ceiling, there is a problem that the ceiling tex is broken because it is fixed to the ceiling tex to install a sealing speaker between the luminaires arranged in close proximity.

The present invention is to solve the above problems, the object is to install a plurality of LED emitters with a speaker in a housing consisting of a single body to simultaneously exhibit the lighting function and speaker function, to install the lighting and speakers To provide a combined lighting speaker that can be carried out at once.

In addition, the present invention provides a lighting combined speaker that is made of a combination structure of the speaker and the LED light emitting body to easily fix the speaker and the LED light emitting body to the housing.

In addition, even if the ceiling is already equipped with a lighting system to provide a ceiling-mounted sealing speaker that can be easily installed in the ceiling structure where necessary, for example, where the lighting is poorly illuminated or where the sound of the speaker is difficult to transmit. have.

In addition, by focusing the light towards the desired place, it can help the listener to focus on the speaker by shining on the speaker or the blackboard, and the light crosses a wider range in one installation location. It is possible to achieve the effect that is visible, and by providing the sound generated from the speaker in a different direction, to provide a combined lighting speaker that can hear the sound in a wider range.

In addition, the inner surface of the housing can also reflect the light to serve as a reflector to provide a light-emitting sealing speaker that can intensively illuminate the desired area by the light emitted from the LED light emitting far.

The combined lighting speaker according to the present invention for achieving the above object has an inner surface that goes into the rear so that the inner space is formed, the inner surface is formed in the plane between the inclined surface facing each other, the ceiling structure, the ceiling structure A housing having an outer edge formed with a perforated coupling hole to be fixed to the fixing screw; It characterized in that it comprises a speaker and an LED light emitting body is mounted at a predetermined position on the inner surface of the housing.

In addition, the speaker and the LED light-emitting body is mounted on the inner surface of the housing, respectively, one pair, the speaker is formed in each of the perforations on the inclined surfaces facing each other, the speaker unit is in close contact with the back of the corresponding perforations grill cover coupled to the grill on the inclined surface It is fixed to be exposed, the LED light-emitting body is characterized in that forming a perforation at a predetermined height in the plane and fixed to the corresponding perforation.

In addition, at least one speaker and at least two LED light-emitting body is mounted on the inner surface of the housing, the speaker is formed at least one or more perforations in a predetermined position of the plane and the speaker unit behind the corresponding perforations The grill cover is tightly coupled so that the grill cover is exposed in a plane, and the LED light emitters are formed on the inclined surfaces facing each other and are fixed to the corresponding perforations.

In addition, the grill cover has a grill seating portion is formed the grill is fitted, a through hole is formed in the center of the grill seating portion, the coupling hole is drilled outwards, the coupling hole is drilled out of the perforations formed on the inner surface, A coupling hole is formed in the front edge of the speaker unit, and includes a dustproof port having a coupling hole formed in a shape corresponding to the front edge. Passing through the respective coupling holes formed in the characterized in that the fastening with a nut.

In addition, the inner surface of the housing is formed by including a plurality of sound absorbing holes, the sound absorbing hole is characterized in that the inner surface is perforated, the sound absorbing material of a material such as polyurethane is attached to the back surface of the perforated network.

There are some differences in the ratio difference of the plane 2c and the covering of the sound absorption hole 5 with the perforation network 9.

In FIG. 1, one speaker 10 is positioned on each of the inclined surfaces 2a and 2b, and two LED emitters 20 are positioned in the plane 2c. In FIG. 10, the speaker 10 is disposed in the plane 2c. 1, the LED light emitting unit 20 is formed on each of the perforations (8) to form a perforation (8) at a certain height on the inclined surfaces (2a, 2b) facing each other and mounted on the corresponding perforations (8) 2 each in 2b).

At least one speaker 10 may be mounted at a predetermined position on the plane 2c, and one LED light emitting body 20 may be mounted on each of the inclined surfaces 2a and 2b to mount at least two or more speakers. Can be.

Since the speaker 10 has a large space because of its size, the width of the plane 2c can be made larger than that of the inclined surfaces 2a and 2b.

On the other hand, the perforated network (9) to prevent the inflow of dust into the sound absorbing hole (5) to look good in appearance, the position between the LED light emitting body 20 located above and below the inclined surface (2a) (2b) In the plane 2c, the speaker 10 may be positioned above and below the speaker 10.

In this embodiment, since the LED light-emitting body 20 is located on the inclined surfaces 2a and 2b of the housing 1, the light is concentrated in one direction depending on the angle formed by the inclined surfaces 2a and 2b. Can help the listener to focus on the speaker by illuminating the speaker or blackboard. On the other hand, in the case where the angle formed by the inclined surfaces 2a and 2b is wide, it is possible to exert an effect that the light is reflected while crossing a wide range.

In addition, the combined lighting speaker according to the present invention can be easily installed even if the ceiling is already equipped with lighting facilities, for example, where the lighting is not well illuminated or where the sound of the speaker is not transmitted well. At the time of construction, a plurality of the present invention can be arranged and installed at regular intervals, and wiring work according to lighting and speaker installation can also be performed at the same time.

As described above with reference to the drawings illustrating an LED light-emitting body according to the present invention and an illumination combined speaker using the same, but the present invention is not limited by the embodiments and drawings disclosed herein, the description of the present invention Of course, various modifications may be made by those skilled in the art within the scope of the idea.
