It should be appreciated that the present application can be embodied in various forms without departing from the spirit or central characteristics thereof, and that the description and drawings are to be considered in an illustrative sense and not for the purpose of restriction.

[0035] In the description of the present application, it needs to be understood that in the embodiments shown in the drawings, the indication of direction or positional relationship (such as up, down, left, right, front and back, etc.) is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation. When the position of these elements is changed, the indication of these directions is also changed accordingly.

[0036] In addition, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0037] Referring to FIGS. 1 and 2, an embodiment of the present application provides a soft light air cushion 100 for cooperating with a lamp 200 to perform soft light processing on light emitted by the lamp 200. The soft light air cushion 100 of the present application includes a cushion main body 10 and a pressure relief valve 30.

[0038] The cushion main body 10 is used to perform soft light processing on light, and an air filling cavity 101 is arranged inside the cushion main body 10, which is used for air filling to enable the cushion main body 10 to be full and swollen.

[0039] The pressure relief valve 30 is arranged on the cushion main body 10, and the pressure relief valve 30 includes a valve main body 31, an adjusting column 33, and a sealing member 34. The valve main body 31 is connected with the cushion main body 10, and an air pressure relief passage 311 is arranged inside the valve main body 31 and communicates with the air filling cavity 101. A pressure relief port 312 is arranged on the valve main body 31 and communicates with the air pressure relief passage 311. The sealing member 34 is connected to the end of the adjusting column 33, the adjusting column 33 is movably arranged in the air pressure relief passage 311 through the pressure relief port 312, and the sealing member 34 can seal the pressure relief port 312. When the air pressure in the air filling cavity 101 exceeds a set threshold, the adjusting column 33 can move relative to the valve main body 31 to make the sealing member 34 disengage from the pressure relief port 312, so that the pressure relief valve 30 performs pressure relief.

[0040] In some embodiments of the present application, the opposite surfaces of the two sides of the cushion main body 10 are a light transmission surface 11 and a soft light surface 12, respectively. The light transmission surface 11 is transparently arranged and used for the transmission of light. The soft light surface 12 is arranged opposite to the light transmission surface 11, and is used for soft light processing on light.

[0041] In some examples, the light-transmitting surface 11 of the cushion body 10 can be made of thermoplastic polyurethane elastomer (TPU for short), which has high strength, high toughness, wear resistance, oil resistance and other excellent comprehensive performance, and can not only ensure the effective transmission of light, but also ensure the elasticity and toughness of the cushion body 10 as a whole.

[0042] In some examples, the soft light surface 12 of the cushion body 10 can be made of soft light lattice cloth. When light is incident on the soft light surface 12 of the cushion body 10, the texture and structure of the soft light lattice cloth can cause the light to be reflected and refracted multiple times, making the light softer and more uniform.

[0043] In some embodiments of the present application, the cushion body 10 can be made of thermoplastic polyurethane elastomer and soft light lattice cloth to form the light-transmitting surface 11 part and the soft light surface 12 part, respectively, and then the two parts are connected together by sewing or bonding.

[0044] The light-transmitting surface 11 of the cushion body 10 is used to connect with the lamp 200, and the light emitted by the lamp 200 can enter the inside of the cushion body 10 through the light-transmitting surface 11, and then be processed by the soft light surface 12 to be emitted from the soft light surface 12 of the cushion body 10.

[0045] In some examples, the light-transmitting surface 11 of the cushion body 10 can be provided with a wave-shaped outer contour. In some examples, the soft light surface 12 of the cushion body 10 can be provided with a wave-shaped outer contour, or a planar outer contour.

[0046] In some embodiments of the present application, an air port 13 can be provided on the cushion body 10, and the air port 13 is in communication with the inflation cavity 101. The air port 13 is used for the inflation device to deliver gas into the inflation cavity 101 to achieve the fullness of the cushion body 10.

[0047] In some examples, the soft light air cushion 100 further comprises an air nozzle 14 movably arranged at the air port 13 to open or close the air port 13. When it is necessary to inflate the inflation cavity 101, the air port 13 can be opened by the air nozzle 14, and the inflation device is connected to inflate the inflation cavity 101. When the cushion body 10 is inflated to the working state, the air port 13 can be closed by the air nozzle 14 to ensure the sealing of the inflation cavity 101.

[0048] 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 cushion body 10 to open or close the air port 13. In some examples, the air nozzle 14 can also be arranged in a plug-in structure relative to the air port 13, and the air nozzle 14 is inserted into the air port 13 to close the air port 13, and the air nozzle 14 is separated from the air port 13 to open the air port 13.

[0049] Further, in combination with FIGS. 3-5, in some embodiments of the present application, the soft light air cushion 100 further comprises a pressure relief valve 30, which can automatically relieve the pressure of the inflation cavity 101 to avoid damage to the cushion body 10 due to excessive pressure.

[0050] In some examples, the pressure relief valve 30 can be provided in more than one, and multiple pressure relief valves 30 work together to enhance the pressure relief efficiency.

[0051] The pressure relief valve 30 is arranged on the cushion body 10, and the pressure relief valve 30 comprises a valve body 31, an adjusting column 33, and a sealing member 34. The valve body 31 is connected with the cushion body 10, and the valve body 31 is internally provided with a pressure relief passage 311 in communication with the inflation cavity 101. The valve body 31 is provided with a pressure relief port 312 in communication with the pressure relief passage 311. The sealing member 34 is connected to the end of the adjusting column 33, the adjusting column 33 is movably arranged in the pressure relief passage 311 through the pressure relief port 312, and the sealing member 34 can seal the pressure relief port 312. When the air pressure in the inflation cavity 101 exceeds a set threshold, the adjusting column 33 can move relative to the valve body 31 to make the sealing member 34 disengage from the pressure relief port 312, so that the pressure relief valve 30 relieves pressure.

[0052] In some examples, as shown in FIG. 1, the cushion body 10 can be provided with a mounting port 16, which is in communication with the inflation cavity 101. The pressure relief valve 30 is fixed at the mounting port 16. The inner wall of the mounting port 16 can be provided with a sealing structure to ensure the sealing of the connection between the pressure relief valve 30 and the cushion body 10.

[0053] In some embodiments of the present application, referring to FIG. 5, the valve body 31 can comprise a main body portion 313 and a boss portion 314. The main body portion 313 is open at both ends and hollow inside, and the internal space of the main body portion 313 forms a mounting cavity 315. The two ends of the main body portion 313 are respectively a valve port 316 and a through port 317.

[0054] The boss portion 314 is arranged on the inner side wall of the main body portion 313, and the boss portion 314 protrudes from the inner side wall of the main body portion 313. The boss portion 314 is annular, and the interior of the boss portion 314 forms the pressure relief port 312.

[0055] The boss portion 314 is arranged in the interior of the main body portion 313 to separate the mounting cavity 315 in the interior of the main body portion 313 into a transition passage 318 and a pressure relief passage 311. The transition passage 318 and the pressure relief passage 311 are arranged on the two sides of the boss portion 314 respectively, and the transition passage 318 communicates with the pressure relief passage 311 through the pressure relief port 312. Among them, the transition passage 318 is arranged close to the valve port 316, and the pressure relief passage 311 is arranged close to the through port 317.

[0056] In some embodiments of the present application, the valve body 31 can further comprise a connecting seat 319. The connecting seat 319 is arranged inside the body portion 313 and close to the through opening 317 of the body portion 313. The outer wall of the connecting seat 319 is fixed to the inner bottom wall of the body portion 313, and the connecting seat 319 is provided with a through opening communicated with the mounting cavity 315.

[0057] In some examples, the valve body 31 can further comprise a guide portion 320. The guide portion 320 is fixed to the connecting seat 319, and the guide portion 320 is arranged on the side of the connecting seat 319 facing the valve port 316. The guide portion 320 is internally provided with a guide channel 321 communicated with the mounting cavity 315.

[0058] In some embodiments of the present application, the adjusting column 33 can comprise a column body 331 and a connecting body 332. The connecting body 332 is plate-shaped and can abut against the surface of the boss portion 314. One end of the column body 331 is connected to the surface of the connecting body 332, and the other end of the column body 331 is arranged in the guide channel 321 of the guide portion 320.

[0059] In some examples, the pressure relief valve 30 further comprises a sealing member 34. The sealing member 34 is sleeved on the column body 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 through the pressure relief port 312, the connecting body 332 can abut against the boss portion 314 through the sealing member 34 to seal the pressure relief port 312, or the connecting body 332 drives the sealing member 34 to move away from the pressure relief port 312 to release the pressure of the pressure relief valve 30.

[0060] The sealing member 34 can be made of flexible materials such as silica gel or rubber. The sealing member 34 can comprise a first sealing portion 341 in the shape of a column and a second sealing portion 342 in the shape of a ring. The first sealing portion 341 is open at both ends and hollow inside, and the second sealing portion 342 is arranged close to one end of the first sealing portion 341 and annularly arranged outside the first sealing portion 341.

[0061] When the sealing member 34 is assembled with the adjusting column 33, the first sealing portion 341 is sleeved on the outside of the column body 331, and the surface of the second sealing 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 sealing portion 342 away from the surface of the connecting body 332 is used to abut against or move away from the surface of the boss portion 314.

[0062] In addition, in some examples, the adjusting column 33 can further comprise an adjusting button 333. The adjusting button 333 is arranged on the side surface of the connecting body 332 away from the column body 331, and the adjusting button 333 protrudes from the surface of the connecting body 332.

[0063] When the adjusting column 33 and the sealing member 34 are assembled in the valve body 31, the column body 331 and the first sealing part 341 are arranged in the pressure relief opening 312 of the boss part 314, the connecting body 332 and the second sealing part 342 are arranged in the transition passage 318, and part of the column body 331 is arranged in the pressure relief passage 311, and the end of the column body 331 away from the connecting body 332 is movably arranged in the guide passage 321.

[0064] When the adjusting column 33 moves relative to the valve body 31, the guide passage 321 can provide positioning and guidance for the adjusting column 33, so as to ensure the stability of the movement of the adjusting column 33 relative to the valve body 31.

[0065] When the pressure relief valve 30 is installed in the cushion body 10, the installation cavity 315 of the pressure relief valve 30 is in communication with the inflation cavity 101 of the cushion body 10, that is, the inflation cavity 101 of the cushion body 10 is in communication with the pressure relief passage 311 through the opening of the valve body 31 and the transition passage of the connecting seat 319. When the air pressure in the inflation cavity 101 of the cushion body 10 is too large, that is, exceeds the pressure relief value of the pressure relief valve 30, the air pressure in the interior of 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 sealing of the pressure relief opening 312, so that the inflation cavity 101 is in communication with the external environment through the pressure relief passage 311 and the pressure relief opening 312, thereby realizing the pressure relief of the pressure relief valve 30.

[0066] In some embodiments of the present application, the pressure relief valve 30 can further include a spring 35, the spring 35 is arranged in the pressure relief passage 311 and is sleeved 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 at the position where the pressure relief opening 312 is arranged. Specifically, the spring 35 can abut against the inner top wall of the main body part 313 of the valve body 31, and can also abut against the bottom wall of the boss part 314. The spring 35 is sleeved on the outside of the column body 331 of the adjusting column 33, and the end of the spring 35 abuts against the surface of the boss part 314 facing the opening 317.

[0067] When the pressure relief valve 30 is in pressure relief, 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 of the pressure relief valve 30 is completed, that is, the air pressure in the inflation cavity 101 is smaller than the pressure relief value of the pressure relief valve 30, the spring 35 is elastically stretched to reset the adjusting column 33, so as to realize the sealing of the sealing member 34 to the pressure relief opening 312.

[0068] In some examples, the valve body 31 can further include a column shell 322, and the column shell 322 is arranged in the pressure relief passage 311. Part of the adjusting column 33 arranged in the pressure relief passage 311 is arranged in the column shell 322, the spring 35 is arranged in the interior of the column shell 322, and the end of the column shell 322 abuts against the inner wall of the valve body 31 at the position where the pressure relief opening 312 is arranged, so as to realize the assembly of the spring 35 on the adjusting column 33.

[0069] In addition, in some examples, the valve body 31 can further include a brim portion 323 and a valve cover 324. The brim portion 323 is annular, and the brim portion 323 is annularly arranged at the end of the body portion 313 where the valve port 316 is arranged.

[0070] The valve cover 324 is arranged at the valve port 316 of the body portion 313, and the valve cover 324 is provided with a vent hole 325. The pressure relief channel 311 can be in communication with the external environment through the pressure relief port 312, the transition channel 318, and the vent hole 325. In some examples, multiple vent holes 325 can be arranged on the valve cover 324.

[0071] In some embodiments of the present application, the pressure relief valve 30 can further include a valve shell 36. The valve body 31 can be connected to the pad body 10 through the valve shell 36.

[0072] The valve shell 36 is open at both ends and hollow inside, and the valve shell 36 is fixedly arranged in the mounting port 16. The inside of the valve shell 36 is in communication with the inflation cavity 101 of the pad body 10 through the end opening of the valve shell 36.

[0073] In some examples, the inner wall of the valve shell 36 is provided with an internal thread, and the outer wall of the valve body 31 is provided with an external thread that is screw-fitted to the internal thread. Through the screw-fitting of the external thread and the internal thread, the valve body 31 can be screw-fitted in the inside of the valve shell 36.

[0074] In other examples, the valve body 31 and the valve shell 36 can also be detachably connected in other forms, such as being fixed by snap-fitting between the valve body 31 and the valve shell 36 through buckles and slots, or being fixed by interference fit between the valve body 31 and the valve shell 36.

[0075] When the pressure relief valve 30 of the present embodiment is connected to the pad body 10, the valve shell 36 can be first connected to the mounting port 16 of the pad body 10. A sealing structure is arranged at the connection between the valve shell 36 and the pad body 10 to ensure the sealing of the connection of the valve shell 36 at the mounting port 16. After the valve shell 36 is fixed to the pad body 10, the valve body 31 is installed in the inside of the valve shell 36 through the butt joint of the internal thread and the external thread, thereby completing the assembly of the pressure relief valve 30 on the pad body 10.

[0076] In some examples, the pressure relief valve 30 further includes a sealing ring 37, which can be made of rubber or silicone. The sealing ring 37 is arranged between the brim portion 323 of the valve body 31 and the end face of the valve shell 36 to ensure the sealing of the connection between the valve body 31 and the valve shell 36.

[0077] Referring to FIGS. 6 and 7, the embodiment of the present application further provides a light system 1000, which comprises the lamp 200 and the soft light air cushion 100. The structure of the soft light air cushion 100 has been described above and will not be repeated here. The lamp 200 is connected to the cushion main body 10, and the light emitted by the lamp 200 is soft light processed by the soft light surface 12 of the cushion main body 10 and then emitted from the soft light surface 12 of the cushion main body 10.

[0078] In some embodiments of the present application, the lamp 200 can be a cloth lamp, a panel lamp, or a light emitting element in other structures.

[0079] When the lamp 200 is a cloth lamp, it can comprise a lamp main body 201 and a lamp strip arranged on the lamp main body 201. The lamp strip can emit light, and is fixed on one side surface of the lamp main body 201. The lamp main body 201 can comprise a waterproof cloth, a flexible support and a power board.

[0080] The waterproof cloth can prevent external liquid from entering the inside of the cloth lamp, ensure the normal and effective use of the cloth lamp, and ensure the 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, thereby facilitating the user to transport and store. The power board is electrically connected with the lamp strip, so as to realize the light emission of the lamp strip.

[0081] In some examples, the lamp 200 can further comprise a connecting plug 202. One end of the connecting plug 202 can be electrically connected with the power board, and the other end of the connecting plug 202 can be electrically connected with an external power source, so as to realize the power supply of the lamp 200 and ensure the normal light emission of the lamp strip.

[0082] When the cloth lamp is connected with the soft light air cushion 100, the cloth lamp is connected on the outside of the light transmission surface 11 of the cushion main body 10. The cloth lamp can be fixed on the cushion main body 10 by adhesion, or can be fixed on the cushion main body 10 by being sleeved on the pressure relief valve 30 and the air nozzle 14 through the connecting hole, or can be connected with the cushion main body 10 by other connection modes, such as buckle clamping, fastener fixing, etc.

[0083] When the cloth lamp is connected on the surface of the cushion main body 10, the lamp strip of the cloth lamp faces the light transmission surface 11 of the cushion main body 10. The light emitted by the lamp strip can enter the inflation cavity 101 through the light transmission surface 11 of the cushion main body 10, and then is soft light processed by the soft light surface 12 and emitted from the soft light surface 12 of the cushion main body 10.

[0084] Referring to FIG. 8, in some embodiments of the present application, the lamp 200 can also be a lamp bead arranged in an array. The lamp bead is arranged in the inflation cavity 101 of the cushion main body 10.

[0085] The lamp bead can be directly fixed on the inner side wall of the pad main body 10, and the light-emitting surface of the lamp bead faces the soft light surface 12 of the pad main body 10. The light emitted by the lamp bead can be emitted to the soft light surface 12 and then emitted to the outside of the pad main body 10 through the soft light processing of the soft light surface 12 of the pad main body 10.

[0086] For the soft light air cushion 100 and the light system 1000 of the present application, the light system 1000 comprises 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 soft light processed through the soft light air cushion 100. The soft light air cushion 100 comprises the pad main body 10 and the pressure relief valve 30, and the pressure relief valve 30 comprises the valve main body 31, the adjusting column 33 and the sealing piece 34. When the air pressure in the inflation cavity 101 of the pad main body 10 exceeds the set threshold value, the adjusting column 33 can move relative to the valve main body 31 to make the sealing piece 34 separate from the pressure relief port 312 of the valve main body 31 to release pressure. Thus, the internal air pressure of the pad main body 10 can be effectively regulated and controlled through the pressure relief valve 30, so as to avoid the case that the pad main body 10 is damaged due to excessive pressure, ensure that the soft light air cushion 100 is normally and effectively used, and ensure that the light system 1000 can provide high-quality light and shadow effect for photography and videography work.

[0087] Referring to FIGS. 9 and 10, an embodiment of the present application provides a soft light air cushion 100 for cooperating with a lamp 200 to soft light process the light emitted by the lamp 200. The soft light air cushion 100 of the present application comprises a pad main body 10 and an air passage module 20.

[0088] The pad main body 10 is used for soft light processing of light. The pad main body 10 is internally provided with an inflation cavity 101, and the inflation cavity 101 is used for inflation so that the pad main body 10 can be filled and inflated.

The light-transmitting surface 11 is transparently arranged and used for light transmission. The soft light surface 12 is oppositely arranged with the light-transmitting surface 11 and is used for soft light processing of light.

[0091] When the pad body 10 is matched with the lamp 200, the lamp 200 can be assembled to the light-transmitting surface 11 of the pad body 10, or can be assembled to the inside of the pad body 10. The light emitted by the lamp 200 is directed to the soft light surface 12 of the pad body 10, and is directed to the outside of the pad body 10 after being processed by the soft light surface 12.

[0092] 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 performance such as high strength, high toughness, wear resistance, and oil resistance, and can not only ensure the effective transmission of light, but also ensure the elasticity and toughness of the pad body 10 as a whole.

[0093] In some examples, the soft light surface 12 of the pad body 10 can be made of soft light lattice cloth. When the light is directed to the soft light surface 12 of the pad body 10, the texture and structure of the soft light lattice cloth can cause the light to be reflected and refracted multiple times, making the light softer and more uniform.

[0094] In some embodiments of the present application, the pad body 10 can be made of thermoplastic polyurethane elastomer and soft light lattice cloth to form the light-transmitting surface 11 part and the soft light surface 12 part respectively, and then the two parts are connected together by sewing or bonding.

[0096] In some examples, the lamp 200 can be detachably connected to the pad body 10, for example, the lamp 200 can be bonded and fixed to the pad body 10 by magic tape, or the connection between the lamp 200 and the pad body 10 can be achieved by clamping the buckle clamping hole. In other examples, the lamp 200 and the pad body 10 can be arranged in an inseparable integrated structure to ensure the stability of the connection structure of the soft light air cushion 100 and the lamp 200 as a whole.

[0097] In some examples, the light-transmitting surface 11 of the pad body 10 can be arranged in a wave-shaped outer contour. In some examples, the soft light surface 12 of the pad body 10 can be arranged in a wave-shaped outer contour, or in a planar outer contour.

[0098] In some embodiments of the present application, an air port 13 can be arranged on the pad body 10, and the air port 13 communicates with the inflation cavity 101. The air port 13 is used for the inflation device to deliver gas into the inflation cavity 101 to achieve the fullness of the pad body 10.

[0099] In some examples, the soft light air cushion 100 further comprises an air nozzle 14 movably arranged at the air port 13 to open or close the air port 13. When the air chamber 101 needs to be inflated, the air nozzle 14 can be used to open the air port 13, and the inflation device is connected to inflate the air chamber 101. When the cushion body 10 is inflated to the working state, the air nozzle 14 can be used to close the air port 13 to ensure the sealing of the air chamber 101.

By using the air port 13 to install the ventilation pump 21, the fitting port 15 can be omitted to effectively ensure the sealing and structural stability of the entire cushion body 10.

[0105] The air pump 21 can be arranged on the light-transmitting surface 11 of the cushion main body 10 or the soft light surface 12 of the cushion main body 10. When the air pump 21 is arranged on the light-transmitting surface 11, the soft light surface 12 of the cushion main body 10 can be avoided, and the high-quality soft light effect of the soft light air cushion 100 can be ensured. When the air pump 21 is arranged on the soft light surface 12, the lamp 200 and the cushion main body 10 can be effectively and closely assembled on the light-transmitting surface 11 of the cushion main body 10, and the light can be effectively transmitted to the inside of the cushion main body 10 through the light-transmitting surface 11.

When the air pump 21 is turned on, the gas in the external environment can be delivered to the inflation cavity 101 through the second ventilation opening 212 and the first ventilation opening 211, so as to realize the inflation of the inflation cavity 101.

[0110] In some embodiments of the present application, the air pump 21 can further include an air pump motor 214, and the air pump motor 214 is arranged in the inside of the pump shell 213.

[0111] The air pump motor 214 includes a motor body 2141 and a blade 2142 arranged on the motor body 2141. The blade 2142 is in a curved arc shape, and multiple blades 2142 are arranged on the side wall of the motor body 2141 in a circumferential direction.

When the air pressure in the inflation cavity 101 of the pad body 10 is too large, that is, exceeds the pressure relief threshold of the pressure relief valve 30, the air pressure inside the pad body 10 can drive the adjusting column 33 to move relative to the valve body 31, so that the sealing member 34 moves away from the sealing of the pressure relief opening 312, so that the inflation cavity 101 is in communication with the external environment through the pressure relief passage 311 and the pressure relief opening 312, thereby realizing the pressure relief of the pressure relief valve 30.

[0146] In some embodiments of the present application, the pressure relief valve 30 can further include a spring 35, which is arranged in the pressure relief channel 311 and sleeved on the outside of the adjusting column 33, and the end of the spring 35 abuts against the inner wall at the position of the pressure relief port 312 of the valve body 31. The spring 35 is sleeved on the outside of the column body 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.

[0147] When the pressure relief valve 30 is in pressure relief, 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 completes the pressure relief, i.e., the air pressure in the inflation cavity 101 is less than the pressure relief valve value, the spring 35 is elastically elongated to reset the adjusting column 33, so as to realize the sealing of the sealing member 34 to the pressure relief port 312.

[0148] In use of the air pump 21 of the present example, the pressure sensor 22 detects that the pressure value in the inflation cavity 101 is lower than the set pressure value, and the mat body 10 under the set pressure value can ensure the inflation state. 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 air pump motor 214 to make the air pump motor 214 open, so that the blade 2142 rotates to make the air in the external environment pass through the through hole 2173 on the shell 217 and the second air vent 212 of the pump housing 213, pass through the inside of the pump housing 213, pass through the first air vent 211 of the pump housing 213 and the through hole 2173 on the shell 217 into the inflation cavity 101 of the mat body 10, and realize the inflation of the mat body 10.

[0149] When the air pressure in the inflation cavity 101 of the mat body 10 is too large, i.e., exceeds the pressure relief valve value of the pressure relief valve 30, the air pressure in the inside of the mat 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 sealing of the pressure relief port 312, so that the inflation cavity 101 is communicated 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.

[0150] In some examples, as shown in FIG. 14, the pressure relief valve 30 can be cancelled in the soft light air cushion 100, and the deflation of the mat body 10 is realized by the air pump 21. That is, the air pump 21 can be opened according to the pressure value signal, and can deflate the inflation cavity 101 through the second air vent 212. The pressure relief control of the air pump 21 is more accurate and intelligent, and can effectively and timely respond to the pressure relief operation.

[0151] Specifically, when the pressure sensor 22 detects that the pressure value in the inflation cavity 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 make the ventilation motor 214 open, so that the blade 2142 rotates to make the gas in the inflation cavity 101 pass through the through hole 2173 on the shell 217 and the first ventilation port 211 of the pump shell 213, pass through the inside of the pump shell 213, pass through the second ventilation port 212 of the pump shell 213 and the through hole 2173 on the shell 217, and be transported to the external environment, so as to realize the deflation of the pad body 10.

[0152] Referring to FIGS. 15 and 16, the embodiment of the present application further provides a light system 1000, which comprises the lamp 200 and the soft light air cushion 100. The structure of the soft light air cushion 100 has been described above and will not be repeated here. The lamp 200 is connected to the pad body 10, and the light emitted by the lamp 200 is soft light processed by the soft light surface 12 of the pad body 10 and emitted from the soft light surface 12 of the pad body 10.

[0153] In some embodiments of the present application, the lamp 200 can be a cloth lamp, can be a panel lamp, and can also be a light emitting element in different structural forms.

[0154] When the lamp 200 is a cloth lamp, it can comprise a lamp body 201 and a lamp strip arranged on the lamp body 201. The lamp strip can emit light, and is fixed on one side surface of the lamp body 201. The lamp body 201 can comprise a waterproof cloth, a flexible support and a power board.

[0155] The waterproof cloth can prevent external liquid from entering the inside of the cloth lamp, ensure the normal and effective use of the cloth lamp, and ensure the 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, thereby facilitating the user to transport and store. The power board is electrically connected with the lamp strip, so as to realize the light emission of the lamp strip.

[0156] In some examples, the lamp 200 can further comprise a connection plug 202. One end of the connection plug 202 can be electrically connected with the power board, and the other end of the connection plug 202 can be electrically connected with an external power supply, so as to realize the power supply of the lamp 200 and ensure the normal light emission of the lamp strip.

[0157] In some examples, the lamp 200 can be detachably connected to the pad body 10. For example, the lamp 200 can be fixed on the pad body 10 by magic tape, or the connection between the lamp 200 and the pad body 10 can be realized by clamping the buckle clamping hole. In other examples, the lamp 200 and the pad body 10 can be arranged in an inseparable integrated structure, so as to ensure the stability of the connection structure of the soft light air cushion 100 and the lamp 200 as a whole.

[0158] When the cloth lamp is connected with the soft light air cushion 100, the cloth lamp can be detachably connected outside the light-transmitting surface 11 of the cushion main body 10. The cloth lamp can be fixed on the cushion main body 10 by adhesion, or can be fixed on the cushion main body 10 by being sleeved on the pressure relief valve 30 and the air nozzle 14 through the connecting hole, or can be connected with the cushion main body 10 by other connection modes, such as buckle clamping, fastener fixing, etc.

[0159] When the cloth lamp and the soft light air cushion 100 are set as an integral structure which cannot be detached, the air pump 21 and the pressure relief valve 30 can be directly fixed and connected on the cloth lamp.

[0160] When the cloth lamp is connected on the surface of the cushion main body 10, the lamp strip of the cloth lamp faces the light-transmitting surface 11 of the cushion main body 10. The light emitted by the lamp strip can enter the air filling cavity 101 through the light-transmitting surface 11 of the cushion main body 10, and then is processed by the soft light surface 12 to be emitted from the soft light surface 12 of the cushion main body 10.

[0161] In some embodiments of the present application, the control module for regulating the opening or closing of the air pump 21 can be electrically connected with the power board, so as to control the opening or closing of the lamp strip. In some examples, the cloth lamp can be independently provided with a regulating module, which is independently provided relative to the control module. The regulating module is electrically connected with the power board to control the opening or closing of the lamp strip.

[0162] Referring to FIG. 17, in some embodiments of the present application, the lamp 200 can also be a lamp bead arranged in an array. The lamp bead is arranged in the air filling cavity 101 of the cushion main body 10.

[0163] The lamp bead can be directly fixed on the inner side wall of the cushion main body 10, and the light-emitting surface of the lamp bead faces the soft light surface 12 of the cushion main body 10. The light emitted by the lamp bead can be emitted to the soft light surface 12, and then is emitted to the outside of the cushion main body 10 through the soft light processing of the soft light surface 12 of the cushion main body 10.

[0164] For the soft light air cushion 100 and the light system 1000 of the present application, the light system 1000 comprises 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 soft light processed through the soft light air cushion 100. The soft light air cushion 100 comprises a cushion main body 10 and an air passage module 20, and the air passage module 20 comprises an air passage pump 21 and a pressure sensor 22. The pressure sensor 22 can measure the pressure value of the air filling cavity 101 inside the cushion main body 10, and the air passage pump 21 comprises a first air passage 211 connected with the air filling cavity 101 and a second air passage 212 in communication with the external environment. The air passage pump 21 is electrically connected with the pressure sensor 22, and is opened or closed according to the pressure value signal. When the air passage pump 21 is opened, the air filling cavity 101 can be inflated through the first air passage 211, so that when the pressure of the cushion main body 10 is insufficient, the pressure sensor 22 can cooperate with the air passage pump 21 to timely and effectively regulate the internal air pressure of the cushion main body 10, ensure the fullness of the cushion main 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 effect for photography and videography work.

[0165] In the present application, the lamp can be a flexible lamp. The flexible lamp can include a non-curlable cloth lamp and a curlable cloth lamp.

[0166] The lamp can also be a rigid lamp. The rigid lamp can include a rigid support frame. The rigid support frame can keep the shape of the lamp fixed, thereby keeping the rigidity of the lamp.

[0167] For the sake of description and understanding, the following will be illustrated by taking the flexible lamp as an example.

[0168] As shown in FIG. 18, the light system 1000 comprises the soft light air cushion 100 and the lamp 200. The lamp 200 can be connected to the soft light air cushion 100, and the light emitted by the lamp 200 can pass through the soft light air cushion 100 to irradiate to the external environment. On the one hand, the soft light air cushion 100 can effectively soften the light emitted by the lamp 200, thereby improving the illumination effect of the lamp 200. On the other hand, the soft light air cushion 100 facilitates the flat use of the lamp 200, and facilitates the adjustment of the installation position and the irradiation angle of the lamp 200, thereby greatly improving the convenience and flexibility of the lamp 200.

[0169] FIG. 18 is a structural schematic view of the lamp 200 of the light system 1000 of the present application when connected to the soft light air cushion 100. FIG. 19 is a sectional view of the structure shown in FIG. 18. FIG. 20 is a structural schematic view of the lamp 200 of the light system 1000 of the present application when separated from the soft light air cushion 100.

[0170] Referring to FIGS. 18-20, the present application provides a lamp 200 which can be connected with the soft light air cushion 100. The lamp 200 comprises a lamp body 201, a light emitting element 300 and an air exchange device 400. The lamp body 201 comprises a surface layer 210 and a bottom layer 220 which are oppositely arranged. The surface layer 210 is used to connect with the soft light air cushion 100. When the soft light air cushion 100 is matched with the lamp 200, the soft light air cushion 100 is arranged on the surface layer 210 of the lamp 200. The light emitting element 300 is arranged between the surface layer 210 and the bottom layer 220. The light emitted by the light emitting element 300 can pass through the surface layer 210 and irradiate to the external environment. The air exchange device 400 is arranged on the lamp body 201. The air exchange device 400 is located outside the light emitting element 300. The air exchange device 400 can be used to communicate with the soft light air cushion 100 to inflate the soft light air cushion 100.

[0171] When the lamp 200 is used, the lamp 200 is connected with the soft light air cushion 100. The light emitting element 300 can emit light to irradiate to the external environment. On the one hand, the surface layer 210 is attached to the soft light air cushion 100 to soften the light emitted by the lamp 200. On the other hand, the lamp 200 is laid on the soft light air cushion 100 so that the lamp 200 and the soft light air cushion 100 can move and rotate synchronously. This facilitates the staff to adjust the light emitting angle and the uniformity of the light of the lamp 200 and improves the lighting effect.

[0172] When the lamp 200 is connected with the soft light air cushion 100, the air exchange device 400 communicates with the soft light air cushion 100. The air exchange device 400 can inflate the soft light air cushion 100 so that the soft light air cushion 100 is inflated. On the one hand, the air exchange device 400 can directly input external air into the soft light air cushion 100 without the staff using the air pump to inflate the soft light air cushion 100. Thus, the operation steps of inflating the soft light air cushion 100 can be effectively simplified and the work efficiency is improved. On the other hand, the air exchange device 400 is integrated on the soft light air cushion 100. This facilitates the adaptation of the air exchange device 400 and the soft light air cushion 100 and reduces the overall volume of the lamp 200 and the soft light air cushion 100.

[0173] Referring to FIGS. 18-20, in this embodiment, the lamp 200 can comprise the light emitting element 300. The light emitting element 300 is accommodated between the surface layer 210 and the bottom layer 220. The light emitting element 300 can emit light towards the surface layer 210.

[0199] When the air pressure in the soft light air cushion 100 is insufficient and needs to be inflated, the air exchanger 420 can inflate the soft light air cushion 100 with external air through the first air vent 411, thereby effectively improving the inflation efficiency of the soft light air cushion 100 and improving the use efficiency of the lamp 200.

[0200] The housing 410 can be provided with a second air vent 412. The second air vent 412 is used for air exchange with the external environment, so that external air can enter the housing 410 through the second air vent 412.

[0201] The air exchanger 420 comprises a motor (not shown in the figure), a rotating wheel 421, and a plurality of fan blades 422 arranged on the rotating wheel 421.

In other embodiments, the ventilator 420 can be directly electrically connected with the connection plug 202 through an electric connection line.

[0209] The first air vent 411 of the shell 410 can be provided with an air valve 450 to control the opening and closing of the first air vent 411, thereby improving the reliability and stability of the ventilation device 400.

[0210] In some embodiments, the air valve 450 is a one-way stop valve, so that gas can only be output from the shell 410 to the soft light air cushion 100 through the air outlet, thereby preventing the gas in the soft light air cushion 100 from leaking out of the soft light air cushion 100 through the first air vent 411.

[0211] In other embodiments, the air valve 450 is an automatic stop valve. The automatic stop valve can be electrically connected with the ventilation control module 430 or the main control module. The ventilation control module 430 or the main control module can control the automatic stop valve to open or close the first air vent 411.

[0212] In other embodiments, when the ventilation device 400 is deflated for the soft light air cushion 100, the automatic stop valve is opened to enable the gas in the soft light air cushion 100 to be released to the outside.

[0213] In some embodiments, the ventilation device 400 can be arranged in the bottom layer 220 and the surface layer 210. The shell 410 is arranged in the bottom layer 220 and the surface layer 210. One end of the shell 410 protrudes outward beyond the surface of the bottom layer 220, and the end of the shell 410 protruding beyond the surface layer 210 can be accommodated in the inflation cavity 101 of the soft light air cushion 100. The first air vent 411 is arranged on the end of the shell 410 accommodated in the soft light air cushion 100, and the second air vent 412 is arranged on the end of the shell 410 protruding beyond the surface of the bottom layer 220.

[0214] The second air vent 412 of the shell 410 can be located on the side of the bottom layer 220 away from the surface layer 210. The first air vent 411 of the shell 410 can be located on the side of the surface layer 210 away from the bottom layer 220. The air exchange device 400 is sealingly connected to the soft light air cushion 100. Part of the air exchange device 400 can extend into the soft light air cushion 100, and the first air vent 411 extends into the interior of the soft light air cushion 100. Thus, after the lamp 200 and the soft light air cushion 100 are assembled, the air exchange device 400 can quickly inflate the soft light air cushion 100 through the first air vent 411, thereby effectively improving the inflation efficiency of the soft light air cushion 100, and improving the use efficiency of the lamp 200 and the soft light air cushion 100.

[0215] In some embodiments, the air exchange device 400 can be arranged on the bottom layer 220. The air exchange device 400 extends in a direction away from the surface layer 210. The first air vent 411 of the air exchange device 400 is provided with an air exchange pipe, and one end of the air exchange pipe away from the air exchange device 400 is in communication with the soft light air cushion 100, thereby facilitating the inflation of the soft light air cushion 100. Moreover, the air exchange device 400 arranged on the bottom layer 220 does not interfere with the arrangement of the light emitting element 300, can expand the light emitting area of the light emitting element 300, and improve the lighting effect.

[0216] In the present embodiment, the lamp 200 can further include a pressure sensor. The pressure sensor is used to detect and obtain a pressure value signal of the soft light air cushion 100. The pressure sensor can be electrically connected to the air exchange control module 430 to transmit the pressure value signal to the air exchange control module 430. The air exchange control module 430 can control the air exchanger 420 according to the pressure value signal to start or stop the air exchanger 420.

[0217] The air pressure in the soft light air cushion 100 is in a preset pressure range, thereby ensuring the softening effect of the soft light air cushion 100 on the light emitted by the lamp 200.

[0218] The pressure sensor can detect and obtain the pressure value signal of the soft light air cushion 100 and transmit the pressure value signal to the air exchange control module 430 and / or the main body control module. After receiving the pressure value signal, the air exchange control module 430 and / or the main body control module can determine whether the pressure value signal is within the preset pressure range.

[0219] If the pressure value signal is lower than the preset pressure range, the air exchange control module 430 and / or the main body control module can control the air exchanger 420 to start, thereby inflating the soft light air cushion 100.

[0220] If the pressure value signal is within the preset pressure range, the air exchange control module 430 and / or the main body control module can control the air exchanger 420 to stop working, thereby stopping the inflation of the soft light air cushion 100.

[0221] If the pressure value signal is higher than the preset pressure range, the ventilation control module 430 and / or the main body control module can control the air valve 450 to open to deflate the soft light air cushion 100.

[0222] In some embodiments, the pressure sensor can be arranged in the housing 410. The pressure sensor can extend into the soft light air cushion 100 along with the housing 410, so as to facilitate detection of the pressure value signal in the soft light air cushion 100. In other embodiments, the pressure sensor can be in communication with the inside of the soft light air cushion 100 through the air outlet, so as to be able to detect and obtain the pressure value signal in the soft light air cushion 100.

[0223] In other embodiments, the pressure sensor can be arranged outside the ventilation device 400. The pressure sensor is located between the soft light air cushion 100 and the surface layer 210. When the soft light air cushion 100 is inflated and expanded, the soft light air cushion 100 presses the pressure sensor on the lamp 200, so that the pressure sensor can detect the pressure parameter of the pressure exerted by the soft light air cushion 100 on the lamp 200, thereby obtaining the pressure value signal in the soft light air cushion 100.

[0224] In other embodiments, the pressure sensor is arranged in the soft light air cushion 100. The main body control module and / or the ventilation control module 430 can further include a wireless signal module. The pressure value signal obtained by the pressure sensor can be transmitted to the main body control module and / or the ventilation control module 430 through the wireless signal module.

[0225] In the related art, as the lamp 200 is used, the lamp 200 will heat up. The heat generated when the lamp 200 is used will be transmitted to the soft light air cushion 100, so that the gas in the soft light air cushion 100 expands, thereby causing the pressure value in the soft light air cushion 100 to exceed the preset pressure range. On the one hand, the expansion of the gas in the soft light air cushion 100 will affect the softening effect of the light emitted by the soft light air cushion 100 on the lamp 200; on the other hand, the expansion of the gas in the soft light air cushion 100 will affect the safety and service life of the soft light air cushion 100.

[0226] FIG. 22 is an enlarged view of the structure at A in FIG. 19.

[0227] Referring to FIGS. 18-20 and 22, in the present embodiment, the lamp 200 can further include a deflation device 500. The deflation device 500 can be arranged on the lamp main body 201. The deflation device 500 can be located outside the light emitting element 300. The deflation device 500 is used to communicate with the soft light air cushion 100 to be able to deflate the gas in the soft light air cushion 100.

[0228] The deflation device 500 comprises a valve body 510 and a valve core 520. The valve body 510 is provided with a release passage 511 which communicates the soft light air cushion 100 with the external environment. The valve core 520 is movably arranged in the release passage 511 to enable the release passage 511 to be opened or closed. When the air pressure in the soft light air cushion 100 exceeds the preset pressure range, the valve core 520 moves to open the release passage 511, so that the air in the soft light air cushion 100 can be released to the outside through the release passage 511.

[0229] Referring to FIGS. 19 and 22, in the present embodiment, the valve body 510 is provided with an abutting plate 512 in the release passage 511. The outer peripheral wall of the abutting plate 512 abuts against the inner peripheral wall of the release passage 511. The abutting plate 512 is provided with a third air vent. The opening and closing of the third air vent can enable the release passage 511 to be opened or closed.

[0230] The valve core 520 comprises a shielding plate 521, an extension column 522 and an elastic member 523. The shielding plate 521 is arranged on the side of the abutting plate 512 away from the soft light air cushion 100. The shielding plate 521 is arranged relative to the third air vent to be capable of covering the third air vent. The extension column 522 extends along the extension direction of the release passage 511. One end of the extension column 522 is connected to the shielding plate 521, and the other end of the extension column 522 passes through the third air vent. The elastic member 523 is located on the side of the abutting plate 512 close to the soft light air cushion 100. One end of the elastic member 523 is connected to the valve body 510, and the other end of the elastic member 523 is connected to the extension column 522. The elastic member 523 can exert a force on the extension column 522 to enable the shielding plate 521 to cover the third air vent, thereby closing the third air vent.

[0231] When the pressure value of the air in the soft light air cushion 100 exceeds the preset pressure range, the air in the soft light air cushion 100 exerts a pressure on the shielding plate 521. The pressure is greater than the elastic force exerted by the elastic member 523 on the extension column 522, so that the shielding plate 521 is opened, and the air in the soft light air cushion 100 is released to the outside through the release passage 511.

[0232] When the pressure value of the air in the soft light air cushion 100 decreases to within the preset pressure range, the elastic force exerted by the elastic member 523 on the extension column 522 is greater than the pressure of the air in the soft light air cushion 100, so that the shielding plate 521 covers the abutting plate 512, the third air vent is closed, and the release passage 511 is disconnected, thereby preventing the air in the soft light air cushion 100 from being released to the outside through the release passage 511.

[0233] In some embodiments, the elastic member 523 can be a spring, an elastic silica gel member, an elastic rubber member, etc.

[0234] In some embodiments, the air release device 500 can be an automatic pressure relief valve. The automatic pressure relief valve can be electrically connected with the ventilation control module 430 and / or the main body control module, so that the ventilation control module 430 and / or the main body control module can determine whether to release the gas according to the pressure value signal detected by the pressure sensor.

[0235] The automatic pressure relief valve includes a valve body 510, a valve core 520, and a motor (not shown in the figure). The valve body 510 is provided with a release passage 511, and the valve core 520 is movably arranged in the release passage 511. In other embodiments, the motor is electrically connected with the ventilation control module 430 and / or the main body control module. The ventilation control module 430 and / or the main body control module can drive the valve core 520 to move through the motor, so as to control the opening and closing of the release passage 511.

[0236] The air release device 500 can be arranged through the bottom layer 220 and the surface layer 210. The gas inlet of the release passage 511 can be located on the side of the surface layer 210 away from the bottom layer 220. The gas outlet of the release passage 511 can be located on the side of the bottom layer 220 away from the surface layer 210.

[0237] In some embodiments, the air release device 500 can be arranged on the surface layer 210. The air release device 500 extends in the direction away from the bottom layer 220 of the surface layer 210. The gas inlet of the release passage 511 can be arranged at one end of the air release device 500 away from the surface layer 210. The gas outlet of the release passage 511 can be arranged on the circumferential wall of the valve body 510.

[0238] In other embodiments, the air release device 500 can be arranged on the bottom layer 220. The gas inlet of the release passage 511 can be connected with the soft light air cushion 100 through a pipeline, so that the gas in the soft light air cushion 100 can be released to the outside through the pipeline and the release passage 511.

[0239] Referring to FIGS. 18-22, in the present application, when the lamp 200 is used in cooperation with the soft light air cushion 100, the lamp 200 is connected to the soft light air cushion 100.

[0240] The ventilation device 400 is connected with the soft light air cushion 100. The ventilation device 400 is started to inflate the soft light air cushion 100. Thus, the soft light air cushion 100 can be quickly inflated, the operation steps of the lamp 200 and the soft light air cushion 100 are simplified, the use efficiency and convenience of the lamp 200 and the soft light air cushion 100 are improved, and the working intensity of the workers is reduced.

[0241] The pressure sensor transmits the pressure value signal of the soft light air cushion 100 detected and obtained to the ventilation control module 430. When the ventilation control module 430 determines that the pressure value signal is within the preset pressure range, the ventilation control module 430 controls the ventilator 420 to stop running, so as to complete the inflation of the soft light air cushion 100.

[0242] When the pressure of the soft light air cushion 100 exceeds the preset pressure range, the air release device 500 releases the gas in the soft light air cushion 100. Thus, the air pressure in the soft light air cushion 100 is reduced, so that the air pressure is maintained within the preset pressure range. Thus, the convenience, safety, reliability and stability of the lamp 200 in use can be ensured.

[0243] Referring to FIGS. 18 and 20, the present application also provides a light system 1000, which can include the soft light air cushion 100 and the lamp 200 as described above. The soft light air cushion 100 is provided with an air charging cavity 101. The lamp 200 is connected to the soft light air cushion 100. The air exchange device can be in communication with the air charging cavity 101 to charge the air charging cavity 101.

[0244] As shown in FIG. 20, the soft light air cushion 100 can be provided with a first mounting hole 17. The air exchange device 400 can be accommodated and fixed in the first mounting hole 17, so that the soft light air cushion 100 and the air exchange device 400 are sealingly connected.

[0245] When the air exchange device 400 is engaged in the first mounting hole 17, the air exchange device 400 can suck the external gas into the shell 410 through the second air inlet 412, and then transmit the gas to the soft light air cushion 100 through the first air inlet 411. Thus, the soft light air cushion 100 can be supplied with gas.

[0246] The soft light air cushion 100 can be provided with a second mounting hole 18. The air release device 500 can be accommodated and engaged in the second mounting hole 18, so that the air release device 500 and the soft light air cushion 100 are sealingly connected.

[0247] Referring to FIG. 20, the soft light air cushion 100 is further provided with a magic tape 19. When the air exchange device 400 is engaged in the first mounting hole 17 and the air release device 500 is engaged in the second air release groove, the magic tape 19 can be bent towards the lamp 200, and the magic tape 19 can be attached to the edge 230 to connect and limit the lamp 200 on the soft light air cushion 100, so that the connection strength of the soft light air cushion 100 and the lamp 200 can be improved.

[0248] When the lamp 200 is connected to the soft light air cushion, the air exchange device 400 is inserted into and engaged in the first mounting hole 17. The air exchanger 420 is started to suck the external gas into the shell 410 through the second air inlet, and then input the gas into the soft light air cushion through the first air inlet. The air exchange device 400 is adapted to the soft light air cushion to quickly and efficiently charge the soft light air cushion, effectively simplifying the air charging steps of the soft light air cushion 100 and improving the working efficiency of the soft light air cushion 100 and the lamp 200.

[0249] When the lamp 200 is connected to the flexible air cushion, the air release device 500 extends into and engages with the second mounting hole 18. During use of the light system 1000, after the flexible air cushion expands due to heat, the gas in the flexible air cushion will exert pressure on the shielding plate 521 to cause the third air vent to open, thereby allowing the gas in the flexible air cushion to be discharged to the outside through the release passage 511.
