[0032] See also Figure 1 An embodiment of the present application provides a light emitting device 100, which can provide lighting for users to take photos and videos, and improve the quality of image capture. The light emitting device 100 includes a lamp body 10 and a light source 20.

[0033] Among them, a sealed inflatable cavity 101 is provided inside the lamp body 10. An air port 102 connected to the inflatable cavity 101 is provided on the lamp body 10, and the air port 102 can be used to inflate to expand the lamp body 10. The light source 20 is arranged on the lamp body 10, and the light source 20 includes a lamp board 21, lamp beads 22 and a focusing lens 23. There are multiple lamp beads 22 and focusing lenses 23, and multiple lamp beads 22 are arranged at intervals on the lamp board 21. The opposite side surfaces of the lamp beads 22 are respectively a mounting surface 221 and a light-emitting surface 222, and the mounting surface 221 of the lamp beads 22 is connected to the lamp board 21; the light-emitting surface 222 of each lamp bead 22 is provided with a focusing lens 23, and the light emitted by the lamp bead 22 is focused by the focusing lens 23 and then emitted through the lamp body 10.

[0034] In some embodiments of the present application, Figure 2 As shown, the lamp body 10 is generally columnar, and can be configured to be a cylindrical shape, a square column shape, etc.

[0035] The shape of the lamp body 10 can be determined according to actual usage requirements. In some examples, the lamp body 10 can also be set to a spherical shape, a cubic shape, or other regular polyhedron shapes, irregular three-dimensional shapes, etc.

[0036] In some embodiments of the present application, the lamp body 10 may be made of a flexible material, such as cloth, silicone, rubber, etc. A sealed gas-filled cavity 101 is formed inside the lamp body 10 , and an air port 102 communicating with the gas-filled cavity 101 is formed on the lamp body 10 .

[0037] Gas can be filled into the inflation cavity 101 through the air port 102, and the lamp body 10 is deformed and expanded into a columnar structure after being inflated; the gas in the inflation cavity 101 can also be discharged through the air port 102, so that the lamp body 10 is deformed and can be compressed, which is convenient for users to store and carry.

[0038] In addition, in addition to the gas column lamp and the air cushion lamp shown in the above embodiments, the light emitting device 100 can also be a cloth lamp, that is, there is no need to set an air outlet on the lamp body 10, and the lamp body 10 can be directly made of soft light cloth.

[0039] In some embodiments of the present application, the lamp body 10 includes a cylindrical main body 11 and end caps connected to both ends of the main body 11. Both end caps are hemispherical, and the two end caps are respectively a first end cap 12 and a second end cap 13.

[0040] In some examples, the gas port 102 is disposed on the main body 11 and is disposed near a connection between the first end portion 12 and the main body 11 , or is disposed near a connection between the second end portion 13 and the main body 11 .

[0041] The first end cap 12 and the second end cap 13 can be connected to both ends of the main body 11 by sewing, or can be integrally connected to the end of the main body 11. The first end cap 12, the second end cap 13 and the main body 11 enclose a gas-filled cavity 101.

[0042] Combination Figure 3 and Figure 4 As shown, in some embodiments of the present application, the light emitting device 100 further includes a light source 20 , which is disposed on the lamp body 10 , and includes a lamp board 21 , lamp beads 22 and a focusing lens 23 .

[0043] There are multiple lamp beads 22 and condenser lenses 23, and multiple lamp beads 22 are arranged at intervals on the lamp board 21. The two opposite surfaces of the lamp beads 22 are respectively a mounting surface 221 and a light-emitting surface 222, and the mounting surface 221 of the lamp beads 22 is connected to the lamp board 21. A condenser lens 23 is provided on the light-emitting surface 222 of each lamp bead 22, and the light emitted by the lamp bead 22 is condensed by the condenser lens 23 and then emitted through the lamp body 10.

[0044] In some examples, the light source 20 can be disposed inside the lamp body 10, that is, arranged in the gas-filled cavity 101. The light board 21 of the light source 20 is fixed on the inner wall of the main body 11, and the length direction of the light board 21 is consistent with the axial direction of the main body 11. The light board 21 and the inner wall of the main body 11 can be fixed by adhesive or Velcro, and a detachable connection can be achieved by docking of buckles and slots, fastener connection, etc.

[0045] The detachable connection between the lamp panel 21 and the lamp body 10 not only facilitates the assembly of the light source 20 on the lamp body 10, but also facilitates the replacement and maintenance of the light source 20, which is convenient for users. In addition, the lamp panel 21 can also be non-detachable from the lamp body 10 to ensure the stability of the overall structure of the light emitting device 100.

[0046] When the light source 20 is disposed inside the lamp body 10 , the light emitted by the lamp beads 22 is first focused by the focusing lens 23 , and then passes through the lamp body 10 , thereby being emitted to the outside of the lamp body 10 .

[0047] In this example, the lamp body 10 may be a soft light cloth. When the light emitted by the lamp beads 22 passes through the lamp body 10, the soft light cloth can soften the light, making the light softer and providing a better fill light effect.

[0048] In addition, in some other examples, the light emitting device 100 may further include a soft light member. The soft light member is disposed on the lamp body 10, and the soft light member may be disposed on the inner wall of the lamp body 10, or on the outer surface of the lamp body 10. The light emitting surface 222 of the lamp bead 22 faces the soft light member, and the soft light cloth can perform soft light processing on the light, making the light softer and enhancing the fill light effect of the light emitting device 100.

[0049] In some examples, the light source 20 may also be disposed outside the lamp body 10 . The lamp board 21 may be detachably fixed on the outer surface of the main body 11 , and the length direction of the lamp board 21 is consistent with the axial direction of the main body 11 .

[0050] The light source 20 is installed outside the lamp body 10. When the light emitting device 100 needs to be stored, the light source 20 can be removed from the lamp body 10 first, and then the lamp body 10 is deflated, and then the lamp body 10 and the light source 20 are stored. This arrangement prevents the light source 20 from being folded and pulled as the lamp body 10 is inflated and deflated, effectively reducing the number of times the light source 20 is folded and pulled, avoiding damage to the circuit of the light source 20 caused by pulling, and extending the service life of the light source 20.

[0051] The light panel 21 and the outer surface of the main body 11 can be fixed by adhesive or Velcro, and can be detachably connected by docking buckles and slots, connecting with fasteners, etc.

[0052] Furthermore, the structure in which the light source 20 is detachably connected to the outside of the main body 11 can also facilitate users to replace light sources 20 with different lighting effects according to actual usage requirements, thereby enriching the overall usage effect of the light-emitting device 100 and increasing the application range of the light-emitting device 100.

[0053] In this example, the lamp body 10 may include a light-transmitting area and a soft light area that can soften the light. The light source 20 is arranged on the outer surface of the lamp body 10 and corresponds to the light-transmitting area. The light-emitting surface 222 of the lamp bead 22 faces the soft light area.

[0054] The light emitted by the lamp bead 22 first passes through the light-transmitting area and then passes through the soft light area. The soft light area can soften the light, making the light softer and enhancing the fill light effect of the light emitting device 100.

[0055] See also Figure 3 and Figure 4 In some embodiments of the present application, a plurality of lamp beads 22 in a light source 20 are arranged at intervals on a lamp board 21. The lamp board 21 may be a flexible circuit board. The two opposite surfaces of the lamp beads 22 are a mounting surface 221 and a light emitting surface 222, respectively.

[0056] The mounting surface 221 of the lamp bead 22 is connected to the lamp board 21 . The light emitting surface 222 of each lamp bead 22 is provided with a condenser. The light emitted by the lamp bead 22 is condensed by the condenser and then emitted through the lamp body 10 .

[0057] In some examples, the focusing lens 23 may be made of silicone material, which may be formed on the light emitting surface 222 of the lamp bead 22 by a molding process.

[0058] The condenser lens 23 may be hemispherical, and the outer surface of the condenser lens 23 includes a curved condenser surface 231 and a flat connection surface 232. The connection surface 232 of the condenser lens 23 is connected to the light-emitting surface 222 of the lamp bead 22, and the periphery of the connection surface 232 of the condenser lens 23 is flush with the periphery of the light-emitting surface 222 of the lamp bead 22.

[0059] The focusing lens 23 can focus the light emitted by the lamp bead 22 at the light emitting surface 222 into a smaller light emitting angle, which is no greater than 120°, so that the forward light emitting brightness is enhanced. The light emitting angle refers to the angle between the two directions where the light intensity is half of the central intensity.

[0060] By setting the focusing lens 23, the focusing lens 23 can compress the light-emitting angle of the lamp bead 22, so that the light intensity at the center is gradually enhanced. Combined with the soft light effect of the lamp body 10, the center intensity can be further enhanced to improve the fill light illumination effect of the light-emitting device 100.

[0061] In some embodiments of the present application, the lamp beads 22 include multiple white light LED chips 201, multiple yellow light LED chips 202, and multiple RGB LED chips 203. The same type of lamp beads 22 have the same light emission angle after focusing processing by the focusing lens 23.

[0062] In some examples, the light-emitting angles of each lamp bead 22 after being focused by the focusing lens 23 are the same, or the light-emitting angles of multiple lamp beads 22 after being focused by the focusing lens 23 are different, or the light-emitting angles of multiple lamp beads 22 after being focused by the focusing lens 23 may be partially the same.

[0063] Among them, it can be arranged that the light emitted by some lamp beads 22 after being focused by the focusing lens 23 has a luminous angle of no more than 90°, and the light emitted by the remaining part of the lamp beads 22 after being focused by the focusing lens 23 has a luminous angle of no more than 100°.

[0064] In addition, the focusing lenses 23 with different angles can be set according to actual usage requirements, such as according to factors such as the luminous power of the lamp beads 22 and the light emission angle of the lamp beads 22.

[0065] See also Figure 1 In some embodiments of the present application, the light emitting device 100 further includes an electrical connection assembly 30 , which includes an electrical plug interface 31 disposed on the lamp body 10 and an electrical connection circuit board 32 electrically connected to the electrical plug interface 31 .

[0066] The electrical plug interface 31 is used to connect with the control component and the power component to realize charging and power supply to the light emitting device 100. The light emitting device 100 also includes a power line 40, and the electrical connection circuit board 32 is electrically connected to the light board 21 through the power line 40 to realize circuit conduction between the electrical plug interface 31 and the light board 21.

[0067] The electrical plug interface 31 is arranged on the lamp body 10 , so that the integration of the components in the light emitting device 100 is higher, the connection stability of the components is stronger, and the overall storage and carrying of the light emitting device 100 is also convenient.

[0068] In other embodiments of the present application, Figure 5As shown, the lighting device 100 includes an operation control component 50 and an electrical plug interface 31 electrically connected to the operation control component 50, and the operation control component 50 and the electrical plug interface 31 are both arranged outside the lamp body 10. The electrical plug interface 31 is used to dock with the power supply component to realize charging and power supply to the lighting device 100.

[0069] The lighting device 100 further includes an electrical connection wire 60, which is passed through the lamp body 10. One end of the electrical connection wire 60 is connected to the lamp board 21, and the other end of the electrical connection wire 60 is connected to the operation control component 50, so as to realize the electrical connection between the operation control component 50 and the lamp board 21.

[0070] The operation control component 50 can be used by the user to adjust the light source 20, such as turning on or off the light source 20, adjusting its brightness, turning it on or off in different areas, etc. The operation control component 50 and the electrical plug interface 31 are arranged outside the lamp body 10, which can facilitate the user's operation and use.

[0071] In addition, the lighting device 100 further includes a gas charging and discharging valve 70 , which is disposed at the gas inlet 102 of the lamp body 10 . The gas charging and discharging valve 70 can be used for inflating and deflating the lamp body 10 .

[0072] When the light emitting device 100 is to be used, the light body 10 can be inflated through the inflating and discharging valve 70 to expand and fill the light body 10. After the light emitting device 100 is used, the light body 10 can be deflated through the inflating and discharging valve 70 to facilitate the user to store and carry.
