[0024] Reference below Figure 1 and Figure 2 The invention describes a ring-shaped sound-absorbing lamp according to an embodiment of the present invention.

[0025] The annular sound-absorbing lamp of the embodiment of the utility model includes a lamp body 400, which is annular and has a vertical axis. The upper and lower sides of the lamp body 400 are respectively covered with an upper sealing plate 320 and a lower sealing plate 500, so that an inner cavity 001 is formed between the lamp body 400, the upper sealing plate 320 and the lower sealing plate 500, and the upper sealing plate 320 and the lower sealing plate 500 are both made of sound-absorbing material components.

[0026] For example, Figure 1 As shown, the annular sound-absorbing lamp is in the shape of a horizontally arranged sheet as a whole, the lamp body 400 is located at the edge of the annular sound-absorbing lamp, the edge of the lower sealing plate 500 is connected to the inner wall of the lamp body 400 to prevent the lower sealing plate 500 from blocking the light emission of the lamp body 400, and the edge of the upper sealing plate 320 is stacked on the upper side of the top of the lamp body 400. Figure 2The lamp body 400 has a lamp housing, an LED light bar and a light-transmitting plate. A lamp cavity is provided inside the lamp housing. The LED light bar is provided in the lamp cavity. The bottom of the lamp cavity is opened to form a lighting opening so that the light emitted by the LED light bar can be emitted downward. The light-transmitting plate is provided to cover the lighting opening to prevent dust from entering the lamp cavity. In addition, the ring-shaped sound-absorbing lamp also has the advantage of reducing shadows under the lamp.

[0027] By providing an upper sealing plate 320 and a lower sealing plate 500 made of sound-absorbing material, the annular sound-absorbing lamp can absorb sound waves above 1600 Hz. At the same time, a closed cavity is formed between the upper sealing plate 320, the lower sealing plate 500 and the lamp body 400, so that the entire structure of the annular sound-absorbing lamp forms a resonant sound-absorbing structure that can absorb medium and low frequency sounds of 355-1400 Hz, thereby broadening the sound absorption frequency range of the entire sound-absorbing lamp to meet the needs of indoor sound environment design; the annular sound-absorbing lamp is used indoors, which is conducive to improving the indoor language clarity and the efficiency of communication, and has a good application value in the sound and light environment design of office space and classroom space.

[0028] In some embodiments of the present invention, a ring-shaped outer sleeve 310 is disposed on the outer periphery of the lamp body 400, and the outer sleeve 310 is a sound-absorbing material component, which can further improve the absorption effect of high-frequency sound waves.

[0029] In some embodiments of the present invention, the outer sleeve 310 and the upper sealing plate 320 are an integral component, which is convenient for production.

[0030] In some embodiments of the utility model, the outer set 310 and the upper sealing plate 320 are collectively referred to as an outer shell, and the outer shell is provided with a plurality of heat dissipation through holes 330, and the heat dissipation through holes 330 are provided above the lamp body 400. The plurality of heat dissipation through holes 330 are sequentially arranged at intervals along the circumference of the lamp body 400, and the heat dissipation through holes 330 are not connected to the inner cavity 001, and the arrangement of the heat dissipation through holes 330 is conducive to the heat dissipation of the lamp body 400.

[0031] In some embodiments of the present invention, the lamp body 400 is in a polygonal ring shape, and the outer set 310 includes a plurality of strips. The number of sides of the lamp body 400 is equal to the number of strips. The plurality of strips are sequentially arranged along the circumference of the lamp body 400, and each strip is connected to the upper sealing plate 320, and two adjacent strips are in contact. The plurality of strips are attached to the plurality of sides of the lamp body 400 in a one-to-one correspondence; in this way, during production, the edge of the upper sealing plate 320 can be bent downward to form the strips, and the outer shell can be made by cutting and bending the purchased polyester fiber board, which is convenient for the production of the outer shell.

[0032] In some embodiments of the utility model, the lamp body 400 is in a hexagonal ring shape. In this way, the ring-shaped sound-absorbing lamp can be closer to a circle, and the number of strips included in the outer set 310 is small, and the number of times the edge of the upper sealing plate 320 needs to be bent during production is small, which is convenient for production.

[0033] In some embodiments of the utility model, the upper sealing plate 320 and the lower sealing plate 500 are respectively bonded to the lamp body 400. The strips can also be connected to the lamp body 400 by bonding to make the structure more stable. In this way, the surface of the lamp body 400 can be connected to the upper sealing plate 320 and the lower sealing plate 500 without setting a special connection structure, and the lamp body 400 can be a ring lamp directly purchased on the market, and the ring sound-absorbing lamp can be further made from the existing ring lamp, which is convenient for promotion and use.

[0034] In some embodiments of the utility model, the lamp body 400 is in a ring shape. It should be noted that when the annular sound-absorbing lamp faces a certain sound source, the wavefront of the sound source is a spherical surface, and the projection onto the annular sound-absorbing lamp is a circle; this embodiment, by setting the lamp body 400 in a ring shape and the inner cavity 001 as a cylindrical resonance cavity, can effectively broaden the frequency band of the resonance sound absorption, making the frequency bandwidth of the resonance sound absorption wider, and the sound absorption coefficient changes more smoothly with the frequency in the designed frequency range, which can make the sound quality smoother and reduce the distortion of the sound when used in some sound quality control scenarios.

[0035] In some embodiments of the present invention, the upper sealing plate 320 and the lower sealing plate 500 are both made of polyester fiber material. Polyester fiber has good sound absorption effect and is easy to process, and is suitable as the material of the upper sealing plate 320 and the lower sealing plate 500.

[0036] In some embodiments of the utility model, the annular sound-absorbing lamp further comprises a hanging seat 100, which is arranged above the lamp body 400. The hanging seat 100 is provided with a plurality of slings 200, and the lower ends of the slings 200 are connected to the lamp body 400 or the upper cover plate 320. The number of slings 200 can be three, so that the annular sound-absorbing lamp can also be applied to indoor spaces with a large floor height, thereby increasing the scope of application. The slings 200 can be connected to the top edge of the housing. Of course, the sling 200 can also be connected to the lamp body 400. The lamp body 400 is provided with a hanging point corresponding to each sling 200. Multiple slings 200 are connected to multiple hanging points one by one, and multiple hanging points are evenly arranged on the top of the lamp body 400. When the outer casing 310 and the upper cover plate 320 are an integral component and are provided with a heat dissipation through hole 330, the hanging point can be arranged in the heat dissipation through hole 330, so that the sling 200 can still be connected to the lamp body 400, and the outer casing does not need to bear the weight of the lamp body 400, and the structure is reasonable and stable.
