It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0032] In the description of the present application, it should be understood that in the embodiments shown in the drawings, the indications of directions or positional relationships (such as up, down, left, right, front and back, etc.) are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0034] See also Figure 1 and Figure 2 In one embodiment of the present application, a soft light air cushion 100 is provided. The soft light air cushion 100 is used to cooperate with a lamp 200 to perform soft light processing on the light emitted by the lamp 200. The soft light air cushion 100 of the present application includes a cushion body 10 and a ventilation module 20.

[0035] The pad body 10 is used for softening the light. An air-filling cavity 101 is provided inside the pad body 10, and the air-filling cavity 101 is used for inflating so that the pad body 10 can be filled and expanded.

[0036] The ventilation module 20 includes a ventilation pump 21 and a pressure sensor 22 arranged on the cushion body 10. The pressure sensor 22 is used to measure the pressure value in the inflation cavity 101. The ventilation pump 21 is electrically connected to the pressure sensor 22 to be opened or closed according to the pressure value signal. The ventilation pump 21 includes a first vent 211 connected to the inflation cavity 101 and a second vent 212 connected to the external environment. When the ventilation pump 21 is turned on, the ventilation pump 21 can inflate the inflation cavity 101 through the first vent 211.

[0037] In some embodiments of the present application, the two opposite surfaces of the pad body 10 are respectively a light-transmitting surface 11 and a light-softening surface 12. The light-transmitting surface 11 is transparent and is used for light to pass through. The light-softening surface 12 is arranged opposite to the light-transmitting surface 11 and is used for light softening.

[0038] When the pad body 10 and the lamp 200 are matched, the lamp 200 can be mounted on the light-transmitting surface 11 of the pad body 10, or can be mounted inside the pad body 10. The light emitted by the lamp 200 is emitted to the soft light surface 12 of the pad body 10, and is emitted to the outside of the pad body 10 after being softened by the soft light surface 12.

[0039] In some examples, the light-transmitting surface 11 of the pad body 10 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 10.

[0040] In some examples, the soft light surface 12 of the pad body 10 can be made of soft light checkered cloth. When light is emitted to the soft light surface 12 of the pad body 10, 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 10 can be made of thermoplastic polyurethane elastomer and soft light checkered cloth to respectively form a light-transmitting surface 11 part and a soft light surface 12 part, and then the two parts are connected together by sewing or bonding.

[0042] The light-transmitting surface 11 of the pad body 10 is used to be connected to the lamp 200 . The light emitted by the lamp 200 can enter the interior of the pad body 10 through the light-transmitting surface 11 , and then be softened by the soft light surface 12 and emitted from the soft light surface 12 of the pad body 10 .

[0043] In some examples, the lamp 200 can be detachably connected to the pad body 10, for example, the lamp 200 can be fixed to the pad body 10 by Velcro, or the lamp 200 can be connected to the pad body 10 by snapping through a snap-on snap-on hole. In other examples, the lamp 200 and the pad body 10 can be set as a non-detachable integrated structure to ensure the overall stability of the connection structure between the soft light air cushion 100 and the lamp 200.

[0044] In some examples, the light-transmitting surface 11 of the pad body 10 can be set to a wavy outer contour. In some examples, the light-softening surface 12 of the pad body 10 can be set to a wavy outer contour, or a flat outer contour.

[0045] In some embodiments of the present application, a gas port 13 may be provided on the cushion body 10, and the gas port 13 is connected to the inflation cavity 101. The gas port 13 is used for the inflation device to deliver gas to the inflation cavity 101 to achieve full filling of the cushion body 10.

[0046] In some examples, the soft light air cushion 100 further includes an air nozzle 14, which is movably disposed at the air port 13 to open or close the air port 13. When the inflatable cavity 101 needs to be inflated, the air port 13 can be opened through the air nozzle 14, and the inflatable device can be turned on to inflate the inflatable cavity 101. When the cushion body 10 is expanded to a working state, the air port 13 can be closed through the air nozzle 14 to ensure the sealing of the inflatable cavity 101.

[0047] In some examples, the air nozzle 14 can be rotatably arranged at the air port 13, and the air nozzle 14 can be rotated counterclockwise or clockwise relative to the pad body 10 to open or close the air port 13. In some examples, the air nozzle 14 can also be arranged in a pluggable structure relative to the air port 13, and the air nozzle 14 can be inserted into the air port 13 to close the air port 13, and the air nozzle 14 can be detached from the air port 13 to open the air port 13.

[0048] Further, see 1 to Figure 4 In some embodiments of the present application, the soft light air cushion 100 may further include a ventilation module 20 , which includes a ventilation pump 21 and a pressure sensor 22 arranged on the cushion body 10 .

[0049] The ventilation pump 21 may include a pump housing 213, and the pump housing 213 is hollow inside. The pump housing 213 may be connected to the cushion body 10, and the cushion body 10 may be provided with an assembly port 15 that communicates with the inflation chamber 101, and the pump housing 213 is connected to the assembly port 15. The inner wall of the assembly port 15 may be provided with a sealing structure to ensure the sealing of the connection between the ventilation pump 21 and the cushion body 10.

[0050] When the ventilation pump 21 is disposed on the cushion body 10, a part of the ventilation pump 21 is accommodated in the inflation cavity 101. The end of the ventilation pump 21 with the first ventilation opening 211 is accommodated in the inflation cavity 101, and the end of the ventilation pump 21 with the second ventilation opening 212 extends out of the cushion body 10.

[0051] In some examples, the assembly port 15 may be omitted from the cushion body 10. The ventilation pump 21 is disposed at the air port 13, and the ventilation pump 21 is assembled through the air port 13. By using the air port 13 to install the ventilation pump 21, the assembly port 15 may be avoided, so as to effectively ensure the sealing and structural stability of the cushion body 10 as a whole.

[0052] The ventilation pump 21 can be arranged on the light-transmitting surface 11 of the pad body 10, or on the soft light surface 12 of the pad body 10. When the ventilation pump 21 is arranged on the light-transmitting surface 11, it can avoid occupying the soft light surface 12 of the pad body 10, and ensure the high-quality soft light effect of the soft light air cushion 100. When the ventilation pump 21 is arranged on the soft light surface 12, it can avoid causing an obstruction between the lamp 200 and the pad body 10, and can ensure that the lamp 200 is effectively fitted and assembled on the light-transmitting surface 11 of the pad body 10, and ensure that light effectively passes through the light-transmitting surface 11 and enters the interior of the pad body 10.

[0053] In some embodiments of the present application, a first vent 211 and a second vent 212 are provided on the pump housing 213 , and both the first vent 211 and the second vent 212 are communicated with the interior of the pump housing 213 .

[0054] The pump housing 213 is cylindrical in shape as a whole, and the second vent 212 and the first vent 211 are respectively arranged on the end faces at the upper and lower ends of the pump housing 213. Among them, a plurality of second vents 212 can be arranged, and the plurality of second vents 212 are arranged on the top end face of the pump housing 213 at intervals along the circumference of the pump housing 213.

[0055] The first vent 211 is disposed on the bottom end surface of the pump housing 213 , and the first vent 211 may be arranged in a fan shape. A plurality of first vents 211 may be disposed on the pump housing 213 , and the plurality of first vents 211 are arranged at intervals along the circumference of the pump housing 213 .

[0056] The first vent 211 is connected to the inflation cavity 101 inside the cushion body 10, and the first vent 211 is connected to the second vent 212 through the inside of the pump housing 213. When the ventilation pump 21 is turned on, the gas in the external environment can be transported to the inflation cavity 101 through the second vent 212 and the first vent 211 to achieve inflation of the inflation cavity 101.

[0057] In some embodiments of the present application, the ventilation pump 21 may further include a ventilation motor 214, which is disposed inside the pump housing 213. When the ventilation motor 214 is working, the ventilation pump 21 can inflate the inflation chamber 101.

[0058] The ventilation motor 214 includes a motor body 2141 and blades 2142 disposed on the motor body 2141. The blades 2142 are curved arc structures, and a plurality of blades 2142 are provided. The plurality of blades 2142 are disposed on the side wall of the motor body 2141 at intervals along the circumference of the motor body 2141. When the ventilation pump 21 is working, the motor body 2141 rotates and drives the blades 2142 to rotate, so that the ventilation motor 214 delivers gas from the external environment to the inflation chamber 101, thereby achieving inflation of the inflation chamber 101.

[0059] In some embodiments of the present application, the ventilation module 20 may further include a pressure sensor 22 and a control unit 215. The pressure sensor 22 is used to measure the pressure value in the inflation cavity 101, and the ventilation pump 21 is electrically connected to the pressure sensor 22 to open or close according to the pressure value signal.

[0060] The control unit 215 is electrically connected to the pressure sensor 22, and the control unit 215 can receive the pressure value signal transmitted by the pressure sensor 22, and form a control signal according to the pressure value signal. The control unit 215 is electrically connected to the ventilation motor 214 of the ventilation pump 21 to transmit the control signal to the ventilation pump 21, so that the ventilation motor 214 is turned on or off according to the control signal.

[0061] In some examples, the pressure sensor 22 and the control unit 215 may both be disposed inside the pump housing 213. The pressure sensor 22 may be connected to the air-filled cavity 101 through the first vent 211 to measure the pressure value in the air-filled cavity 101 and obtain a pressure value signal.

[0062] The pressure sensor 22 and the control unit 215 can be electrically connected through a line inside the pump housing 213, and the pressure sensor 22 can transmit a pressure value signal to the control unit 215. The control unit 215 forms a control signal according to the pressure value signal. That is, when the gas pressure in the inflation cavity 101 of the cushion body 10 is insufficient, the control unit 215 can form a corresponding control signal according to the pressure value signal to control the ventilation pump 21 to open and inflate the inflation cavity 101.

[0063] The pressure sensor 22 is arranged inside the pump housing 213, so that the ventilation pump 21 and the pressure sensor 22 can be integrated. By installing the ventilation pump 21 on the cushion body 10, the pressure sensor 22 can be assembled on the cushion body 10, which not only simplifies the assembly of the ventilation module 20 on the cushion body 10, but also optimizes the overall structure of the soft light air cushion 100.

[0064] In some examples, the pressure sensor 22 can also be provided independently of the ventilation pump 21, that is, the pressure sensor 22 can be provided alone in the inflation cavity 101 of the cushion body 10. The pressure sensor 22 arranged in the inflation cavity 101 can timely and effectively measure the pressure value inside the cushion body 10.

[0065] The pressure sensor 22 disposed in the inflation chamber 101 may be electrically connected to the ventilation motor 214 of the ventilation pump 21 through a line, or may be electrically connected to the ventilation motor 214 through wireless communication.

[0066] That is, the soft light air cushion 100 may further include a wireless communication module, and the pressure sensor 22 is electrically connected to the ventilation motor 214 of the ventilation pump 21 through the wireless communication module. The wireless communication module may be a Wi-Fi module, a wireless Bluetooth module, a ZiBee wireless communication module, an NFC module, etc.

[0067] In addition, the ventilation pump 21 may further include a battery 216 . The battery 216 is disposed inside the pump housing 213 , and the battery 216 may be used to power the ventilation motor 214 and the pressure sensor 22 .

[0069] The housing 217 can protect the pump housing 213 and the components disposed inside the pump housing 213, thereby ensuring the overall structural strength and stability of the ventilation pump 21. When the ventilation pump 21 is connected to the cushion body 10, the housing 217 can be connected to the assembly port 15, and a sealing structure can be provided on the inner wall of the assembly port 15 to ensure the sealing of the connection between the ventilation pump 21 and the cushion body 10.

[0070] In some examples, the housing 217 may include an upper cover 2171 and a lower shell 2172. The upper cover 2171 and the lower shell 2172 may be fixed by a threaded connection or by a buckle and a slot docking.

[0071] The upper cover 2171 is connected to the top of the lower shell 2172, and a through hole 2173 is provided on the upper cover 2171 to communicate with the interior of the outer shell 217. A plurality of through holes 2173 may be provided, and the plurality of through holes 2173 are arranged at intervals on the upper cover 2171. A through hole 2174 is provided on the bottom end surface of the lower shell 2172, and the through hole 2174 is provided corresponding to the first vent 211 of the pump housing 213.

[0072] The through hole 2174 may be arranged in a fan shape corresponding to the first vent 211 , or a plurality of through holes 2174 may be arranged at intervals on the bottom end surface of the lower shell 2172 along the circumferential direction of the outer shell 217 .

[0073] When the ventilation pump 21 is connected to the pad body 10, the inflation chamber 101 of the pad body 10 is connected to the interior of the pump housing 213 through the through hole 2174 of the outer shell 217 and the first ventilation port 211 of the pump housing 213, and then connected to the external environment through the second ventilation port 212 of the pump housing 213 and the through hole 2173 on the outer shell 217.

[0074] In some embodiments of the present application, the ventilation pump 21 may further include a sealing valve plate 218 , and the sealing valve plate 218 is used to prevent the ventilation pump 21 from leaking and ensure the inflation efficiency of the ventilation pump 21 .

[0075] The sealing valve plate 218 may include a plate body 2181 and a connecting column 2182 connected to the plate body 2181. The connecting column 2182 is arranged protruding from the surface of the plate body 2181. The pump housing 213 and the bottom of the housing 217 are both provided with connecting holes at corresponding positions, and the connecting column 2182 is passed through the connecting holes, so that the sealing valve plate 218 is connected to the housing 217, so that the plate body 2181 is stopped at the through hole 2173 of the housing 217.

[0076] In some embodiments of the present application, Figure 5As shown, in addition to the above embodiment where the ventilation pump 21 is connected to the cushion body 10, the ventilation pump 21 can also be arranged outside the cushion body 10. The first ventilation port 211 of the ventilation pump 21 is connected to the inflation cavity 101 of the cushion body 10 through the connecting pipe 23.

[0077] One end of the connecting tube 23 is connected to the first vent 211 via the through hole 2174 of the shell 217, and the other end of the connecting tube 23 is connected to the assembly port 15 of the cushion body 10. The interior of the connecting tube 23 is connected to the inflation chamber 101 via the assembly port 15. By setting the connecting tube 23, the ventilation pump 21 can be placed outside the cushion body 10. This setting can simplify the overall structure of the cushion body 10, and can also realize the separate storage of the cushion body 10 and the ventilation pump 21.

[0078] See also Figure 1 , Figure 2 as well as Figure 6 In some embodiments of the present application, the soft light air cushion 100 may further include a pressure relief valve 30, through which the pressure relief valve 30 is used to relieve the pressure of the cushion body 10, thereby preventing the cushion body 10 from being damaged due to excessive pressure, and ensuring the effective and normal use of the soft light air cushion 100. The pressure relief valve 30 may include a valve body 31, an adjustment column 33, and a sealing member 34.

[0079] The pressure relief valve 30 is arranged on the cushion body 10, and the pressure relief valve 30 includes a valve body 31, an adjusting column 33 and a sealing member 34.

When the air pressure in the inflation chamber 101 exceeds the set threshold value, the adjusting column 33 can move relative to the valve body 31 to disengage the sealing member 34 from the pressure relief port 312, so that the pressure relief valve 30 can release the pressure.

[0080] In some examples, the cushion body 10 may be provided with a mounting port 16, which is connected to the inflation chamber 101. The pressure relief valve 30 is fixed at the mounting port 16. The inner wall of the mounting port 16 may be provided with a sealing structure to ensure the sealing of the connection between the pressure relief valve 30 and the cushion body 10.

[0081] In some embodiments of the present application, the valve body 31 may include a main body 313 and a boss 314. The main body 313 is open at both ends and hollow inside, and the internal space of the main body 313 forms a mounting cavity 315. The openings at both ends of the main body 313 are a valve port 316 and a through port 317, respectively.

[0082] The boss portion 314 is disposed on the inner wall of the main body portion 313, and the boss portion 314 protrudes from the inner wall of the main body portion 313. The boss portion 314 is annular, and a pressure relief port 312 is formed inside the boss portion 314.

[0083] The boss portion 314 is arranged inside the main body portion 313 to separate the installation cavity 315 inside the main body portion 313 into a transition channel 318 and a pressure relief channel 311. The transition channel 318 and the pressure relief channel 311 are arranged on both sides of the boss portion 314, respectively, and the transition channel 318 is connected to the pressure relief channel 311 through the pressure relief port 312. Among them, the transition channel 318 is arranged close to the valve port 316, and the pressure relief channel 311 is arranged close to the through port 317.

[0084] In some embodiments of the present application, the valve body 31 may further include a connection seat 319. The connection seat 319 is disposed inside the main body 313 and is disposed close to the through opening 317 of the main body 313. The outer wall of the connection seat 319 is fixed to the inner wall of the main body 313, and the connection seat 319 is provided with a through opening communicating with the installation cavity 315.

[0085] In some examples, the valve body 31 may further include a guide portion 320. The guide portion 320 is fixed on the connection seat 319 and is disposed on the side of the connection seat 319 facing the valve port 316. A guide channel 321 is provided inside the guide portion 320 and communicates with the installation cavity 315.

[0086] In some embodiments of the present application, the adjustment column 33 may include a column 331 and a connector 332, wherein the connector 332 is plate-shaped and can abut against the surface of the boss portion 314. One end of the column 331 is connected to the surface of the connector 332, and the other end of the column 331 is inserted into the guide channel 321 of the guide portion 320.

[0087] In some examples, the pressure relief valve 30 further includes a sealing member 34. The sealing member 34 is sleeved on the column 331 of the adjusting column 33, and the surface of the sealing member 34 can abut against the surface of the connecting body 332. When the adjusting column 33 is movably arranged in the pressure relief channel 311 from the pressure relief port 312, the connecting body 332 can abut against the boss portion 314 through the sealing member 34 so that the sealing member 34 seals the pressure relief port 312, or the connecting body 332 drives the sealing member 34 to separate from the pressure relief port 312 so that the pressure relief valve 30 releases pressure.

[0088] The seal 34 may be made of a flexible material such as silicone or rubber. The seal 34 may include a columnar first seal portion 341 and an annular second seal portion 342. The first seal portion 341 is open at both ends and hollow inside, and the second seal portion 342 is disposed near an end of the first seal portion 341 and is disposed around the outer periphery of the first seal portion 341.

[0089] When the seal 34 is assembled with the adjusting column 33, the first seal portion 341 is sleeved on the outside of the column 331, and the surface of the second seal portion 342 abuts against the surface of the connecting body 332. When the adjusting column 33 moves relative to the valve body 31, the surface of the second seal portion 342 away from the connecting body 332 is used to abut against or disengage from the surface of the boss portion 314.

[0090] When the regulating column 33 and the sealing member 34 of the present application are assembled in the valve body 31, the column 331 and the first sealing portion 341 are inserted into the pressure relief port 312 of the boss portion 314, the connecting body 332 and the second sealing portion 342 are arranged in the transition channel 318, a partial area of ​​the column 331 is accommodated in the pressure relief channel 311, and the column 331 is movably inserted into the guide channel 321 away from the end of the connecting body 332.

[0091] When the adjusting column 33 moves relative to the valve body 31 , the guide channel 321 can provide a certain positioning guide for the adjusting column 33 , thereby ensuring the stability of the movement of the adjusting column 33 relative to the valve body 31 .

[0092] After the pressure relief valve 30 is installed on the cushion body 10, the installation cavity 315 of the pressure relief valve 30 is connected with the inflation cavity 101 of the cushion body 10, that is, the inflation cavity 101 of the cushion body 10 is connected with the pressure relief channel 311 through the through port 317 of the valve body 31 and the port of the connecting seat 319. When the air pressure in the inflation cavity 101 of the cushion body 10 is too high, that is, exceeds the pressure relief threshold of the pressure relief valve 30, the air pressure inside the cushion body 10 can push the regulating column 33 to move relative to the valve body 31, so that the sealing member 34 is separated from the seal of the pressure relief port 312, so that the inflation cavity 101 is connected with the external environment through the pressure relief channel 311 and the pressure relief port 312, thereby achieving pressure relief of the pressure relief valve 30.

[0093] In some embodiments of the present application, the pressure relief valve 30 may further include a spring 35, which is disposed in the pressure relief channel 311 and sleeved and fixed on the outside of the adjusting column 33, and the end of the spring 35 abuts against the inner wall of the valve body 31 where the pressure relief port 312 is provided. The spring 35 is sleeved on the outside of the column 331 of the adjusting column 33, and the end of the spring 35 abuts against the surface of the boss portion 314 facing the through port 317.

[0094] When the pressure relief valve 30 is relieving pressure, the adjusting column 33 moves relative to the valve body 31, which can cause the spring 35 to be elastically compressed. When the pressure relief valve 30 has completed the pressure relief, that is, when the air pressure in the inflation chamber 101 is less than the pressure relief threshold value, the spring 35 elastically stretches to reset the adjusting column 33, thereby achieving the sealing of the pressure relief port 312 by the sealing member 34.

[0095] When the ventilation pump 21 of this example is in use, the pressure sensor 22 detects that the pressure value in the inflation chamber 101 is lower than the set pressure value. The pad body 10 can ensure the filling state under the set pressure value. The pressure sensor 22 feeds back the pressure value signal to the control unit 215. The control unit 215 generates a control signal according to the pressure value signal and transmits the control signal to the ventilation motor 214 to open the ventilation motor 214, thereby causing the blades 2142 to rotate and allowing the air in the external environment to pass through the through hole 2173 on the outer shell 217 and the second vent 212 of the pump housing 213, and enter the inflation chamber 101 of the pad body 10 through the inside of the pump housing 213, the first vent 211 of the pump housing 213 and the through hole 2173 on the outer shell 217, thereby achieving inflation of the pad body 10.

[0096] When the air pressure in the inflation chamber 101 of the cushion body 10 is too high, that is, exceeds the pressure relief valve 30 value of the pressure relief valve 30, the air pressure inside the cushion body 10 can push the adjusting column 33 to move relative to the valve body 31, so that the sealing member 34 is separated from the seal of the pressure relief port 312, so that the inflation chamber 101 is connected with the external environment through the pressure relief channel 311 and the pressure relief port 312, thereby realizing the pressure relief of the pressure relief valve 30.

[0097] Some examples include Figure 7 As shown, the pressure relief valve 30 can be eliminated in the soft light air cushion 100, and the cushion body 10 can be deflated through the ventilation pump 21. That is, the ventilation pump 21 can be opened according to the pressure value signal, and can deflate the inflation cavity 101 through the second ventilation port 212. The pressure relief control of the ventilation pump 21 is more precise and intelligent, and can effectively and timely respond to the pressure relief operation.

[0098] Specifically, when the pressure sensor 22 detects that the pressure value in the inflation chamber 101 is greater than the set pressure value, the pressure sensor 22 can feed back the pressure value signal to the control unit 215. The control unit 215 generates a control signal according to the pressure value signal and transmits the control signal to the ventilation motor 214 to open the ventilation motor 214, thereby causing the blades 2142 to rotate and causing the gas in the inflation chamber 101 to pass through the through hole 2173 on the outer shell 217 and the first vent 211 of the pump housing 213, and then through the interior of the pump housing 213 and through the second vent 212 of the pump housing 213 and the through hole 2173 on the outer shell 217 to be transported to the external environment, thereby achieving deflation of the pad body 10.

[0099] See also Figure 8 and Fig. 9In one embodiment of the present application, a lighting system 1000 is provided, which includes a lamp 200 and the above-mentioned soft light cushion 100. The structure of the soft light cushion 100 has been described above and will not be repeated here. The lamp 200 is connected to the cushion body 10, and the light emitted by the lamp 200 is softly processed by the soft light surface 12 of the cushion body 10 and emitted from the soft light surface 12 of the cushion body 10.

[0100] In some embodiments of the present application, the lamp 200 may be a cloth lamp, a panel lamp, or a light-emitting element of different structural forms.

[0101] When the lamp 200 is a cloth lamp, it may include a lamp body 201 and a light bar disposed on the lamp body 201, the light bar can emit light, and the light bar is fixed to a side surface of the lamp body 201. The lamp body 201 may include a waterproof cloth that fits well, a flexible support member, and a power board.

[0102] 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.

[0103] In some examples, the lamp 200 may further include a connection plug 202. One end of the connection plug 202 may be electrically connected to a power board, and the other end of the connection plug 202 may be electrically connected to an external power source to supply power to the lamp 200 and ensure that the light bar can emit light normally.

[0104] In some examples, the lamp 200 can be detachably connected to the pad body 10, for example, the lamp 200 can be fixed to the pad body 10 by Velcro, or the lamp 200 can be connected to the pad body 10 by snapping through a snap-on snap-on hole. In other examples, the lamp 200 and the pad body 10 can be set as a non-detachable integrated structure to ensure the overall stability of the connection structure between the soft light air cushion 100 and the lamp 200.

[0105] When the cloth lamp is connected to the soft light air cushion 100, the cloth lamp can be detachably connected to the outer side of the light-transmitting surface 11 of the cushion body 10. The cloth lamp can be fixed to the cushion body 10 by bonding, or can be fixed to the cushion body 10 by being sleeved on the pressure relief valve 30 and the air nozzle 14 through the connection hole, or can be connected to the cushion body 10 by other connection methods, such as snap-on connection or fastener fixation.

[0106] When the light cloth and the soft light air cushion 100 are arranged as a non-detachable integrated structure, the ventilation pump 21 and the pressure relief valve 30 can be directly fixedly connected to the light cloth.

[0107] When the light strip is connected to the surface of the pad body 10, the light strip of the light strip faces the light-transmitting surface 11 of the pad body 10. The light emitted by the light strip can enter the air-filled cavity 101 through the light-transmitting surface 11 of the pad body 10, and then be softly treated by the soft light surface 12 and emitted from the soft light surface 12 of the pad body 10.

[0108] In some embodiments of the present application, the control module for regulating the opening or closing of the ventilation pump 21 can be electrically connected to the power board so that the control module controls the opening or closing of the light bar. In some examples, the light arrangement can be independently provided with a control module, and the control module is independently provided with respect to the control module. The control module is electrically connected to the power board to control the opening or closing of the light bar.

[0109] See also Fig.10 In some embodiments of the present application, the lamp 200 may also be lamp beads arranged in an array. The lamp beads are arranged in the air-filled cavity 101 of the pad body 10 .

[0110] The lamp beads can be directly fixed on the inner wall of the pad body 10, and the light-emitting surface of the lamp beads faces the soft light surface 12 of the pad body 10. The light emitted by the lamp beads can be directed toward the soft light surface 12, and then be directed to the outside of the pad body 10 through the soft light treatment of the soft light surface 12 of the pad body 10.

[0111] For the soft light air cushion 100 and the lighting system 1000 of the present application, the lighting system 1000 includes the soft light air cushion 100 and the lamp 200 arranged on the soft light air cushion 100, and the light emitted by the lamp 200 can be softly treated by the soft light air cushion 100. The soft light air cushion 100 includes a cushion body 10 and a ventilation module 20, and the ventilation module 20 includes a ventilation pump 21 and a pressure sensor 22. The pressure sensor 22 can measure the pressure value of the inflation cavity 101 inside the cushion body 10, and the ventilation pump 21 includes a first ventilation port 211 connected to the inflation cavity 101 and a second ventilation port 212 connected to the external environment. The ventilation pump 21 is electrically connected to the pressure sensor 22 to open or close according to the pressure value signal. When the ventilation pump 21 is turned on, it can inflate the inflation chamber 101 through the first vent 211. In this way, when the pressure of the cushion body 10 is insufficient, the pressure sensor 22 cooperates with the ventilation pump 21 to timely and effectively regulate the internal air pressure of the cushion body 10 to ensure the filling state of the cushion body 10 and ensure the normal and effective use of the soft light air cushion 100, so that the soft light air cushion 100 can not only effectively support the lamp 200, but also provide high-quality light and shadow effects for photography and videography operations.
