Description

Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to a balloon lamp. Background Art

[0002] In the field of photography and lighting, especially in application scenarios such as outdoor camping or rescue, it is often necessary to place the light source at a higher position to illuminate a larger area. However, in outdoor open-air environments, the lack of suitable fixing points and the inability to fix the lighting fixtures at a high position have become a major challenge.

[0003] The traditional solution is to place the power supply and light source inside the balloon and use the buoyancy of the balloon to suspend the lamp in the air. However, this method has significant limitations. First, the weight of the entire lamp is large. Especially when high-power lighting is required, the weight of the battery is very large, so the balloon cannot provide enough buoyancy to suspend the lamp to the required height. In addition, since all components of the lamp are installed on the balloon, it is not convenient to adjust the light output of the lamp, which greatly limits the practical performance of this method.

[0028] See also Figures 1 to 6 In this embodiment, a balloon lamp 100 is provided, which includes a lamp body 10, a light guide cable 30 connected to the lamp body 10, and a floating member 20 connected to the light guide cable 30.

[0029] Among them, a light outlet 121 is provided on the lamp body 10, and a light source 114 is provided inside the lamp body 10, and the light emitted by the light source 114 can be emitted from the light outlet 121. The floating member 20 is light-transmissive; an air-filled cavity is formed inside the floating member 20, and the air-filled cavity is used to fill gas so that the floating member 20 can float in the air. The two ends of the light guide cable 30 are respectively a light input end and a light output end, and the light input end is arranged at the light outlet 121 of the lamp body 10, and the light output end is arranged in the air-filled cavity of the floating member 20. The light emitted by the light source 114 is emitted from the light input end of the light guide cable 30, transmitted through the light guide cable 30, and transmitted from the light output end to the inside of the floating member 20 to be emitted by the floating member 20.

[0030] The balloon lamp 100 in this embodiment achieves the effect of high-altitude lighting by placing the lamp body 10 partially on the ground and transmitting the light emitted by the lamp body 10 to the floating member 20 floating in the sky through the light guide cable 30. Compared with the traditional method of placing the lamp body 10 inside the balloon, it greatly reduces the overall weight and solves the problem of insufficient buoyancy due to excessive weight. In addition, the user can also adjust the brightness and other parameters of the light source 114 through the lamp body 10 on the ground, which improves practicality and flexibility.

[0031] See also Figure 3 and Figure 4 In some embodiments, the balloon lamp 100 may include a light shielding cover 40 , which is used to connect the lamp body 10 and the light guide cable 30 and shield excess light emitted from the light outlet 121 .

[0032] In some embodiments, the light shielding cover 40 is provided with one or more through holes 42 , and a light guide cable 30 can be passed through each through hole 42 , so that the light input end of the light guide cable 30 is fixed on the light shielding cover 40 and fixedly connected to the light shielding cover 40 .

[0033] One end of the lamp body 10 is provided with a mounting position, the light outlet 121 of the lamp body 10 is located in the mounting position, and the light shielding cover 40 is detachably connected to the mounting position of the lamp body 10. By fixing the light guide cable 30 to the light shielding cover 40, and then detachably connecting the light shielding cover 40 to the lamp body 10, the speed of connecting and disassembling the light guide cable 30 and the lamp body 10 can be effectively improved, and the installation and disassembly of the light guide cable 30 is convenient.

[0034] It is conceivable that in some other embodiments, the light input end of the light guide cable 30 can also be directly fixed to the light outlet 121 of the lamp holder 111 and bonded or fastened to the side wall of the light outlet 121 to achieve fixation of the light guide cable 30 and the lamp holder 111.

[0035] See also Figure 2 and Figure 3 In some embodiments, the lamp body 10 may include a main body portion 11 and a transition portion 12 .

[0036] The end surface of the main body 11 is provided with a light source 114. One end of the adapter 12 is connected to the main body 11, and an installation position is formed at the end of the adapter 12 away from the main body 11. The light outlet 121 is arranged through the installation position of the adapter 12 for connecting the light shielding cover 40.

[0037] The adapter part 12 and the main body 11 can be connected by screws. When the light shielding cover 40 of different sizes needs to be replaced, the adapter part 12 on the main body 11 needs to be replaced together so that the light shielding cover 40 of different sizes can be fixed to the main body 11.

[0038] See also Figure 4 In some embodiments, a plurality of connecting bosses 41 are provided on the peripheral side of the light shielding cover 40. A plurality of connecting blocks 122 are provided on the end surface of the adapter 12 facing the light shielding cover 40, and the plurality of connecting blocks 122 are enclosed to form the installation position. A connecting slot 123 corresponding to the connecting boss 41 is provided on the inner side wall of each connecting block 122 for connecting with the connecting boss 41.

[0039] The connecting slot 123 includes an opening section 1231 extending along the axial direction of the adapter 12 and a locking section 1232 extending along the circumferential direction of the adapter 12. The opening section 1231 and the locking section 1232 are connected to each other to form an L-shaped slot.

[0040] The connecting boss 41 on the light shielding cover 40 can enter the installation position from the opening section 1231, and then rotate a certain angle so that the connecting boss 41 on the light shielding cover 40 is inserted into the locking section 1232 to achieve the connection between the light shielding cover 40 and the lamp holder 111. The size of the locking section 1232 can match the size of the connecting boss 41, so that when the connecting boss 41 is in the locking section 1232, it can be fixed by interference fit. When it is necessary to remove the light shielding cover 40, the light shielding cover 40 can be rotated in the opposite direction with force so that the connecting boss 41 exits the locking section 1232 and moves out of the opening section 1231, so that the adapter 12 of the light shielding cover 40 can be removed.

[0041] It is conceivable that in some other embodiments, the connection boss 41 on the light shielding cover 40 and the connection slot 123 of the adapter 12 can be interchanged. Of course, the light shielding cover 40 and the lamp body 10 can also be connected by magnetic attraction, buckle connection, screw locking, etc.

[0042] In some embodiments, an optical element may be disposed in the light outlet 121 of the adapter 12. The optical element may be a focusing lens, through which the light passes before entering the light inlet end of the light guide cable 30, focusing the light emitted by the light source 114 and changing the incident angle of the light entering the light inlet end of the light guide cable 30.

[0043] In some other embodiments, the optical element may further include an element for changing the light effect, such as a light homogenizer or a light filter.

[0044] See also Figure 3In some embodiments, the main body 11 may include a lamp head 111. The light source 114 may be disposed on the end surface of the lamp head 111. The light source 114 in the lamp head 111 may include one LED point light source 114 or multiple LED point light sources 114. Each LED point light source 114 may be a single color temperature light source 114, a dual color temperature light source 114, an RGB light source 114, or a mixed light source 114, so that the light source 114 can emit light of different colors, different color temperatures, or different brightness under the control of a control signal.

[0045] In some embodiments, the main body 11 may further include a battery module 112 , which is detachably connected to the lamp head 111 , and the batteries in the battery module 112 can supply power to the light source 114 in the lamp head 111 .

[0046] In some embodiments, the main body 11 may further include a control module 113, which may be detachably connected to the battery module 112 or the lamp head 111. The control module 113 is also provided with control buttons, and the user may control the light emitting parameters of the light source 114 in the lamp head 111 through a combination of multiple control buttons.

[0047] For example, the user can press the brightness adjustment button to increase or decrease the brightness of the light emitted by the lamp head 111 to meet different lighting needs. The user can also use the color temperature adjustment button to adjust the color temperature of the light emitted by the lamp head 111. The user can also use the hue adjustment button to change the hue of the light emitted by the lamp head 111, such as switching between red, green, blue (RGB) and other colors, or mixing multiple color effects to suit occasions that require rich light effects such as photography and stage lighting.

[0048] In some embodiments, a power interface is provided on the control module 113 , and the power interface can be connected to an external mobile power source via a power cord so as to supply power to the lamp head 111 or charge the battery module 112 .

[0049] See also Figure 3 In some embodiments, the float 20 includes a float body 21 and an air nozzle 22. The float body 21 encloses a closed inflation cavity. The air nozzle 22 is disposed on the float body 21 and communicates with the inflation cavity so that the air nozzle 22 can inflate the inflation cavity.

[0050] In some embodiments, the floating member 20 may be in a circular, square, rectangular or hot air balloon shape. That is, the outer shape design of the floating member 20 may be diversified to meet different application requirements and aesthetic requirements. The floating member 20 may also be designed in various shapes such as an elliptical shape and a cylindrical shape to achieve different lighting effects and decorative effects. For example, a spherical floating member 20 may provide all-round uniform lighting, while a cylindrical floating member 20 may achieve directional lighting to meet the lighting requirements of a specific area.

[0051] In some embodiments, the floating body 21 can be made of a light and highly light-transmitting material, such as transparent plastic or film. These materials not only have excellent light-transmitting properties, but also have sufficient strength and durability to withstand the influence of the external environment, such as wind and small-scale collisions, making them suitable for outdoor lighting.

[0052] In some embodiments, the floating body 21 may be a soft light cloth that is light-transmissive and scatters the light passing through it, so that the light emitted from the light-emitting end in the inflation cavity can be emitted after being scattered by the soft light cloth.

[0053] The material of the soft light cloth is made of high light transmittance and high strength fiber material, ensuring that it has sufficient strength and durability while providing excellent light transmittance. The surface of the soft light cloth can evenly scatter light, avoid glare and light spots, and provide a soft and uniform lighting effect. The light it emits is softer and more natural, making it more suitable for photography.

[0054] In addition, the material and color of the diffuser can also be customized according to different application requirements, such as using white or milky white diffuser to provide the best diffused light effect. In addition, the flexibility and plasticity of the diffuser material enable the floating body 21 to be easily folded and unfolded, making it easy to carry and store.

[0055] See also Figure 5 and Figure 6 In some embodiments, the air nozzle 22 on the floating member 20 includes a valve body 221 and a sealing plug 222. The valve body 221 is fixed on the floating body 21, and an air hole 2211 is provided in the valve body 221 to connect the inflation cavity with the outside. The sealing plug 222 is detachably connected in the air hole 2211 and seals the air hole 2211.

[0056] Specifically, the air hole 2211 can be designed as a one-way air intake structure, which can allow gas to enter the inflation cavity when inflated, and automatically close when not inflated to prevent gas leakage. The sealing plug 222 can be made of a soft elastic material, and its shape is closely matched with the air hole 2211, and a quick sealing and unsealing operation can be achieved by pressing in and pulling out.

[0057] The outside of the sealing plug 222 is provided with a grip 2221 for the user to operate during inflation and deflation. The inside of the sealing plug 222 can be provided with a sealing ring so that the sealing plug 222 forms a multiple seal after being inserted into the air hole 2211 to ensure that the air hole 2211 is completely sealed to prevent gas leakage.

[0058] During the inflation operation, the user only needs to pull out the sealing plug 222 and insert the nozzle of the inflation device into the air hole 2211 to inflate. After the inflation is completed, the sealing plug 222 is reinserted into the air hole 2211 to ensure that the gas in the inflation cavity does not leak. During the deflation operation, the user only needs to pull out the sealing plug 222, and the gas can be quickly released through the air hole 2211, which is convenient for storage and carrying.

[0059] It should be understood that the gas filled into the inflation chamber of the floating member 20 by the external inflation device can be selected according to the actual situation. It is generally an inert gas with a density less than that of air, so as to achieve the suspension of the floating member 20 while ensuring safety.

[0060] In some embodiments, a mounting hole is provided on the floating body 21, and the mounting hole is a through structure, and its size and shape match the light guide cable 30 to ensure that the light guide cable 30 can be stably inserted into the mounting hole, so that the light output end of the light guide cable 30 can penetrate into the inflation cavity.

[0061] In some embodiments, a sealing ring is further provided on the floating body 21, which is arranged on the mounting hole and sleeved on the light guide cable 30 to seal the connection between the mounting hole and the light guide cable 30, so as to prevent gas leakage from the mounting hole and ensure the airtightness of the inflation cavity.

[0062] In some embodiments, the light guide cable 30 includes an inner core and a cladding covering the inner core, and the refractive index of the inner core is greater than the refractive index of the cladding.

[0063] Specifically, the inner core is made of a material with a high refractive index, which can be quartz glass or optical plastic with a high refractive index, and has good transparency and refractive index characteristics, and can effectively transmit light. The cladding is made of a material with a lower refractive index, so that light can be effectively transmitted in the inner core through total reflection, minimizing light loss. This allows light to be smoothly transmitted from the lamp body 10 to the floating member 20, and then emitted from the floating member 20, to achieve high-altitude lighting.

[0064] It should be understood that in order to allow the light to be totally reflected in the light-guiding optical fiber, it is necessary to control the incident angle of the light emitted by the light source 114 entering the light inlet end to be greater than the critical angle, so as to achieve total reflection of the light in the light-guiding cable 30. The incident angle can be controlled by the focusing lens of the light outlet 121 or directly by the light source 114.

[0065] In some embodiments, a sheath is further provided on the outside of the light guide cable 30 , and the sheath can be sleeved outside the cladding to protect the light guide cable 30 .

[0066] In summary, the balloon lamp 100 of the present embodiment achieves the effect of high-altitude lighting by placing the light source 114 and the power supply part in the lamp body 10 on the ground, and transmitting the light through the light guide cable 30 to the floating member 20 floating in the sky. Compared with the traditional method of placing the power supply and the light source 114 together inside the balloon, the overall weight is greatly reduced, and the problem of insufficient buoyancy due to excessive weight is solved. The balloon lamp 100 can float to a predetermined height more easily while maintaining a stable and efficient lighting effect. In addition, the user can also adjust the brightness and other parameters of the light source 114 through the lamp body 10 on the ground, which improves practicality and flexibility and is suitable for a variety of scenarios such as camping, rescue and photography.
