[0035] See also Figure 1 and Figure 2 In one embodiment of the present application, a soft light air cushion 10 is provided. The soft light air cushion 10 is used to cooperate with a lamp 20 to perform soft light processing on the light emitted by the lamp 20. The soft light air cushion 10 of the present application includes a cushion body 11 and a pressure relief valve 12.

[0036] The pad body 11 is used for softening the light, and an air-filled cavity 110 is provided inside the pad body 11 . The air-filled cavity 110 is used for inflating so that the pad body 11 can be filled and expanded.

[0037] The pressure relief valve 12 is arranged on the cushion body 11, and the pressure relief valve 12 includes a valve body 121, an adjusting column 123 and a sealing member 124. The valve body 121 is connected to the cushion body 11, and a pressure relief channel 1211 communicating with the inflation chamber 110 is arranged inside the valve body 121, and a pressure relief port 1212 communicating with the pressure relief channel 1211 is opened on the valve body 121. The sealing member 124 is connected to the end of the adjusting column 123, and the adjusting column 123 is movably arranged in the pressure relief channel 1211 through the pressure relief port 1212, and the sealing member 124 can seal the pressure relief port 1212. When the air pressure in the inflation chamber 110 exceeds the set threshold value, the adjusting column 123 can move relative to the valve body 121 to disengage the sealing member 124 from the pressure relief port 1212, so that the pressure relief valve 12 can release the pressure.

[0038] In some embodiments of the present application, the two opposite surfaces of the pad body 11 are respectively a light-transmitting surface 111 and a light-softening surface 112. The light-transmitting surface 111 is transparent and is used for light to pass through. The light-softening surface 112 is arranged opposite to the light-transmitting surface 111 and is used for light softening.

[0039] In some examples, the light-transmitting surface 111 of the pad body 11 can be made of thermoplastic polyurethane elastomer (TPU for short), which has excellent comprehensive properties such as high strength, high toughness, wear resistance, and oil resistance. It can not only ensure the effective passage of light, but also ensure the overall elasticity and toughness of the pad body 11.

[0040] In some examples, the soft light surface 112 of the pad body 11 can be made of soft light checkered cloth. When light is emitted to the soft light surface 112 of the pad body 11, the texture and structure of the soft light checkered cloth can cause the light to be reflected and refracted multiple times, making the light softer and more uniform.

[0041] In some embodiments of the present application, the pad body 11 can be made of thermoplastic polyurethane elastomer and soft light checkered cloth to respectively form a light-transmitting surface 111 part and a soft light surface 112 part, and then the two parts are connected together by sewing or bonding.

[0042] The light-transmitting surface 111 of the pad body 11 is used to be connected to the lamp 20 . The light emitted by the lamp 20 can enter the interior of the pad body 11 through the light-transmitting surface 111 , and then be softened by the soft light surface 112 and emitted from the soft light surface 112 of the pad body 11 .

[0043] In some examples, the light-transmitting surface 111 of the pad body 11 can be set to a wavy outer contour. In some examples, the light-softening surface 112 of the pad body 11 can be set to a wavy outer contour, or a planar outer contour.

[0044] In some embodiments of the present application, a gas port 113 may be provided on the cushion body 11, and the gas port 113 is connected to the inflation cavity 110. The gas port 113 is used for the inflation device to deliver gas to the inflation cavity 110 to achieve full filling of the cushion body 11.

[0045] In some examples, the soft light air cushion 10 further includes an air nozzle 13, which is movably disposed at the air port 113 to open or close the air port 113. When the inflatable cavity 110 needs to be inflated, the air port 113 can be opened through the air nozzle 13, and the inflatable device can be turned on to inflate the inflatable cavity 110. When the cushion body 11 is expanded to a working state, the air port 113 can be closed through the air nozzle 13 to ensure the sealing of the inflatable cavity 110.

[0046] In some examples, the air nozzle 13 can be rotatably arranged at the air port 113, and the air nozzle 13 can be rotated counterclockwise or clockwise relative to the pad body 11 to open or close the air port 113. In some examples, the air nozzle 13 can also be arranged in a pluggable structure relative to the air port 113, and the air nozzle 13 can be plugged into the air port 113 to close the air port 113, and the air nozzle 13 can be opened when it is detached from the air port 113.

[0047] Furthermore, combined with Figures 3 to 5 In some embodiments of the present application, the soft light air cushion 10 further includes a pressure relief valve 12, which can automatically relieve pressure in the inflation cavity 110 to prevent the cushion body 11 from being damaged due to excessive pressure.

[0048] In some examples, more than one pressure relief valve 12 may be provided, and multiple pressure relief valves 12 may cooperate to enhance the pressure relief efficiency.

[0049] The pressure relief valve 12 is arranged on the cushion body 11, and the pressure relief valve 12 includes a valve body 121, an adjusting column 123 and a sealing member 124. The valve body 121 is connected to the cushion body 11, and a pressure relief channel 1211 communicating with the inflation chamber 110 is arranged inside the valve body 121, and a pressure relief port 1212 communicating with the pressure relief channel 1211 is opened on the valve body 121.

When the air pressure in the inflation chamber 110 exceeds the set threshold value, the adjusting column 123 can move relative to the valve body 121 to disengage the sealing member 124 from the pressure relief port 1212, so that the pressure relief valve 12 can release the pressure.

[0050] In some examples, the cushion body 11 may be provided with an installation port 114, which is in communication with the inflation chamber 110. The pressure relief valve 12 is fixed at the installation port 114. The inner wall of the installation port 114 may be provided with a sealing structure to ensure the sealing of the connection between the pressure relief valve 12 and the cushion body 11.

[0051] In some embodiments of the present application, the valve body 121 may include a main body 1213 and a boss 1214. The main body 1213 is open at both ends and hollow inside, and the internal space of the main body 1213 forms a mounting cavity 1215. The openings at both ends of the main body 1213 are valve ports 1216 and through ports 1217, respectively.

[0052] The boss portion 1214 is disposed on the inner side wall of the main body portion 1213, and the boss portion 1214 protrudes from the inner side wall of the main body portion 1213. The boss portion 1214 is annular, and a pressure relief port 1212 is formed inside the boss portion 1214.

[0053] The boss portion 1214 is arranged inside the main body portion 1213 to separate the installation cavity 1215 inside the main body portion 1213 into a transition channel 1218 and a pressure relief channel 1211. The transition channel 1218 and the pressure relief channel 1211 are arranged on both sides of the boss portion 1214, respectively, and the transition channel 1218 is connected to the pressure relief channel 1211 through the pressure relief port 1212. Among them, the transition channel 1218 is arranged close to the valve port 1216, and the pressure relief channel 1211 is arranged close to the through port 1217.

[0054] In some embodiments of the present application, the valve body 121 may further include a connection seat 1219. The connection seat 1219 is disposed inside the main body 1213 and is disposed close to the through opening 1217 of the main body 1213. The outer wall of the connection seat 1219 is fixed to the inner bottom wall of the main body 1213, and the connection seat 1219 is provided with a through opening communicating with the installation cavity 1215.

[0055] In some examples, the valve body 121 may further include a guide portion 1220. The guide portion 1220 is fixed on the connection seat 1219 and is disposed on the side of the connection seat 1219 facing the valve port 1216. A guide channel 1221 is provided inside the guide portion 1220 and is communicated with the installation cavity 1215.

[0056] In some embodiments of the present application, the adjustment column 123 may include a column 1231 and a connector 1232, wherein the connector 1232 is plate-shaped and can abut against the surface of the boss portion 1214. One end of the column 1231 is connected to the surface of the connector 1232, and the other end of the column 1231 is inserted into the guide channel 1221 of the guide portion 1220.

[0057] In some examples, the pressure relief valve 12 further includes a sealing member 124. The sealing member 124 is sleeved on the column 1231 of the adjusting column 123, and the surface of the sealing member 124 can abut against the surface of the connecting body 1232. When the adjusting column 123 is movably arranged in the pressure relief channel 1211 from the pressure relief port 1212, the connecting body 1232 can abut against the boss portion 1214 through the sealing member 124 so that the sealing member 124 seals the pressure relief port 1212, or the connecting body 1232 drives the sealing member 124 to separate from the pressure relief port 1212 so that the pressure relief valve 12 is relieved.

[0058] The seal 124 can be made of a flexible material such as silicone or rubber. The seal 124 can include a columnar first seal portion 1241 and an annular second seal portion 1242. The first seal portion 1241 is open at both ends and hollow inside, and the second seal portion 1242 is disposed near an end of the first seal portion 1241 and is disposed around the outer periphery of the first seal portion 1241.

[0059] When the seal 124 is assembled with the adjusting column 123, the first seal portion 1241 is sleeved on the outside of the column 1231, and the surface of the second seal portion 1242 abuts against the surface of the connecting body 1232. When the adjusting column 123 moves relative to the valve body 121, the surface of the second seal portion 1242 away from the connecting body 1232 is used to abut against or disengage from the surface of the boss portion 1214.

[0060] In addition, in some examples, the adjustment column 123 may further include an adjustment button 1233 . The adjustment button 1233 is disposed on a surface of the connecting body 1232 that is away from the column 1231 , and the adjustment button 1233 is protruded from the surface of the connecting body 1232 .

[0061] When the regulating column 123 and the sealing member 124 of the present application are assembled in the valve body 121, the column 1231 and the first sealing portion 1241 are inserted into the pressure relief port 1212 of the boss portion 1214, the connecting body 1232 and the second sealing portion 1242 are arranged in the transition channel 1218, a partial area of ​​the column 1231 is accommodated in the pressure relief channel 1211, and the column 1231 is movably inserted into the guide channel 1221 away from the end of the connecting body 1232.

[0062] When the adjusting column 123 moves relative to the valve body 121 , the guide channel 1221 can provide a certain positioning guide for the adjusting column 123 , thereby ensuring the stability of the movement of the adjusting column 123 relative to the valve body 121 .

[0063] After the pressure relief valve 12 is installed on the cushion body 11, the installation cavity 1215 of the pressure relief valve 12 is connected with the inflation cavity 110 of the cushion body 11, that is, the inflation cavity 110 of the cushion body 11 is connected with the pressure relief channel 1211 through the through port 1217 of the valve body 121 and the through port of the connecting seat 1219. When the air pressure in the inflation cavity 110 of the cushion body 11 is too high, that is, exceeds the pressure relief valve 12 value of the pressure relief valve 12, the air pressure inside the cushion body 11 can push the regulating column 123 to move relative to the valve body 121, so that the sealing member 124 is separated from the seal of the pressure relief port 1212, so that the inflation cavity 110 is connected with the external environment through the pressure relief channel 1211 and the pressure relief port 1212, thereby realizing the pressure relief of the pressure relief valve 12.

[0064] In some embodiments of the present application, the pressure relief valve 12 may further include a spring 125, which is disposed in the pressure relief channel 1211 and sleeved and fixed on the outside of the adjusting column 123, and the end of the spring 125 abuts against the inner wall of the valve body 121 where the pressure relief port 1212 is provided. Specifically, the spring 125 may abut against the inner top wall of the main body 1213 of the valve body 121, and may also abut against the bottom wall of the boss portion 1214. The spring 125 is sleeved on the outside of the column 1231 of the adjusting column 123, and the end of the spring 125 abuts against the surface of the boss portion 1214 facing the through port 1217.

[0065] When the pressure relief valve 12 is relieving pressure, the adjusting column 123 moves relative to the valve body 121, which can cause the spring 125 to be elastically compressed. When the pressure relief valve 12 has completed the pressure relief, that is, the air pressure in the inflation chamber 110 is less than the pressure relief valve 12, the spring 125 elastically stretches to reset the adjusting column 123, thereby achieving the sealing of the pressure relief port 1212 by the sealing member 124.

[0066] In some examples, the valve body 121 may further include a column housing 1222, which is arranged in the pressure relief channel 1211. The portion of the regulating column 123 located in the pressure relief channel 1211 is penetrated in the column housing 1222, the spring 125 is arranged inside the column housing 1222, and the end of the column housing 1222 abuts against the inner wall of the valve body 121 where the pressure relief port 1212 is provided, thereby realizing the assembly of the spring 125 on the regulating column 123.

[0067] In addition, in some examples, the valve body 121 may further include a brim portion 1223 and a valve cover 1224. The brim portion 1223 is annular and is disposed around the end of the body portion 1213 where the valve port 1216 is disposed.

[0068] The valve cover 1224 is disposed at the valve port 1216 of the main body 1213, and a vent hole 1225 is disposed on the valve cover 1224. The pressure relief channel 1211 can communicate with the external environment through the pressure relief port 1212, the transition channel 1218, and the vent hole 1225. In some examples, a plurality of vent holes 1225 can be provided, and the plurality of vent holes 1225 are arranged at intervals on the valve cover 1224.

[0069] In some embodiments of the present application, the pressure relief valve 12 may further include a valve housing 126. The valve body 121 may be connected to the pad body 11 through the valve housing 126.

[0070] The valve housing 126 is open at both ends and hollow inside. The valve housing 126 is inserted and fixed in the mounting port 114 . The inside of the valve housing 126 is connected to the inflation cavity 110 of the cushion body 11 through its own end openings.

[0071] In some examples, the inner wall of the valve housing 126 is provided with an internal thread, and the outer wall of the valve body 121 is provided with an external thread threadedly matched with the internal thread. Through the threaded matching of the external thread and the internal thread, the valve body 121 can be threadedly fixed inside the valve housing 126.

[0072] In other examples, the valve body 121 and the valve housing 126 may also be detachably connected in other forms, such as the valve body 121 and the valve housing 126 are fixed by snapping together with a snap fit; or, the valve body 121 and the valve housing 126 are fixed by interference fit.

[0073] When the pressure relief valve 12 of this embodiment is connected to the cushion body 11, the valve housing 126 can be first connected to the installation port 114 of the cushion body 11. A sealing structure is provided at the connection between the valve housing 126 and the cushion body 11 to ensure the sealing of the valve housing 126 at the installation port 114. After the valve housing 126 is fixed to the cushion body 11, the valve body 121 is installed inside the valve housing 126 by connecting the internal thread with the external thread, thereby completing the assembly of the pressure relief valve 12 on the cushion body 11.

[0074] In some examples, the pressure relief valve 12 further includes a sealing ring 127, which can be made of rubber or silicone. The sealing ring 127 is arranged between the brim portion 1223 of the valve body 121 and the end surface of the valve housing 126 to ensure the sealing of the connection between the valve body 121 and the valve housing 126.

[0076] In some embodiments of the present application, the lamp 20 may be a cloth lamp, a panel lamp, or a light-emitting element of different structural forms.

[0077] When the lamp 20 is a cloth lamp, it may include a lamp body 21 and a light bar disposed on the lamp body 21, the light bar can emit light, and the light bar is fixed to a side surface of the lamp body 21. The lamp body 21 may include a waterproof cloth that fits well, a flexible support member, and a power board.

[0078] The waterproof cloth can prevent external liquid from entering the interior of the cloth lamp, ensuring the normal and effective use of the cloth lamp and ensuring a long service life of the cloth lamp. The flexible support can realize the bending deformation of the cloth lamp, so that the cloth lamp can be bent and stored for easy transportation and storage by users. The power board is electrically connected to the light strip to realize the light emission of the light strip.

[0079] In some examples, the lamp 20 may further include a connection plug 22. One end of the connection plug 22 may be electrically connected to a power board, and the other end of the connection plug 22 may be electrically connected to an external power source to supply power to the lamp 20 and ensure that the light bar can emit light normally.

[0080] When the cloth lamp is connected to the soft light air cushion 10, the cloth lamp is connected to the outer side of the light-transmitting surface 111 of the cushion body 11. The cloth lamp can be fixed to the cushion body 11 by bonding, or can be fixed to the cushion body 11 by being set on the pressure relief valve 12 and the air nozzle 13 through the connection hole, or can be connected to the cushion body 11 by other connection methods, such as snap-on connection and fastener fixation.

[0081] When the light strip is connected to the surface of the pad body 11, the light strip faces the light-transmitting surface 111 of the pad body 11. The light from the light strip can enter the air-filled cavity 110 through the light-transmitting surface 111 of the pad body 11, and then be softly treated by the soft light surface 112 and emitted from the soft light surface 112 of the pad body 11.

[0082] See also Figure 8 In some embodiments of the present application, the lamp 20 may also be lamp beads arranged in an array. The lamp beads are arranged in the air-filled cavity 110 of the pad body 11 .

[0083] The lamp beads can be directly fixed on the inner wall of the pad body 11, and the light-emitting surface of the lamp beads faces the soft light surface 112 of the pad body 11. The light emitted by the lamp beads can be directed to the soft light surface 112, and then be directed to the outside of the pad body 11 through the soft light treatment of the soft light surface 112 of the pad body 11.

[0084] For the soft light cushion 10 and the lighting system 100 of the present application, the lighting system 100 includes the soft light cushion 10 and the lamp 20 arranged on the soft light cushion 10, and the light emitted by the lamp 20 can be softly treated by the soft light cushion 10. The soft light cushion 10 includes a cushion body 11 and a pressure relief valve 12, and the pressure relief valve 12 includes a valve body 121, an adjusting column 123 and a sealing member 124. When the air pressure in the inflation cavity 110 of the cushion body 11 exceeds the set threshold, the adjusting column 123 can move relative to the valve body 121 so that the sealing member 124 is separated from the pressure relief port 1212 of the valve body 121 to release the pressure, so that the internal air pressure of the cushion body 11 can be effectively regulated by the pressure relief valve 12, and the situation that the cushion body 11 is damaged due to excessive pressure is avoided, so as to ensure the normal and effective use of the soft light cushion 10 and ensure that the lighting system 100 can provide high-quality light and shadow effects for photography and videography.
