[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] First embodiment:

[0044] Reference Figures 1 to 13 The present invention provides a floating projection decorative lamp 10, including a shell 20 and a light-emitting module 30 arranged in the shell 20, the shell 20 includes a main body 21 and a mapping part 22 connected to the bottom of the main body 21; the mapping part 22 has a transmission pattern 23, and the light-emitting module 30 is used to emit light toward the transmission pattern 23, so that the light passing through the transmission pattern 23 forms a projection pattern corresponding to the transmission pattern 23.

[0045] This new floating projection decorative lamp features a compact light module and a simple lighting method, capable of projecting patterns and light spots into the water. It is inflatable, made of light-transmitting materials, and incorporates an internal solar panel, eliminating the need for charging or battery replacement. Furthermore, it incorporates a sensor that controls the light output based on ambient light levels. This new floating projection decorative lamp offers a simple structure, low cost, and compact size, providing a superior user experience.

[0046] It can be understood that, in one embodiment, the light emitting module disposed in the housing emits light toward the mapping portion, and after the light passes through the transmission pattern on the mapping portion, a projection pattern corresponding to the transmission pattern can be presented in water.

[0047] Furthermore, the main body 21 encloses a first accommodation space 24 , the mapping portion 22 is connected to the bottom of the main body 21 and together with the main body 21 encloses a second accommodation space 25 , and the light emitting module 30 is disposed in the second accommodation space 25 .

[0048] It can be understood that the first accommodating space is above the second accommodating space, and the first accommodating space can be inflated to ensure that the floating projection decorative lamp floats in the water. The light-emitting module is arranged in the second accommodating space so that the position of the light-emitting module can be closer to the transmission pattern, thereby maximizing the utilization of the light emitted by the light-emitting module and reducing light attenuation.

[0049] Furthermore, the main body 21 is made of a flexible inflatable material, and the first accommodating space 24 is used to be filled with air; the mapping portion 22 is made of the same material as the main body 21 , and the second accommodating space 25 is smaller than the first accommodating space 24 .

[0050] It can be understood that the main body 21 can be a flexible inflatable material such as rubber, latex, soft plastic, etc. After the first accommodation space is inflated, it can provide buoyancy to the floating projection decorative lamp. The second accommodation space is smaller than the first accommodation space, which can maximize the reduction of the second accommodation space and make the first accommodation space larger, thereby providing greater buoyancy to the floating projection decorative lamp.

[0051] Furthermore, the light emitting module 30 includes a housing 31 and a first light source 32 disposed in the housing 31 . A light opening 33 is provided on a side of the housing 31 facing the transmission pattern 23 , and the first light source 32 is disposed in the light opening 33 .

[0052] It can be understood that the shell 31 is assembled from two shells, the first light source is relatively close to the light opening, and the area of ​​the light opening is larger. This design allows more light emitted by the first light source to pass through the light opening and illuminate the transmission pattern.

[0053] Furthermore, the light emitting module 30 further includes a circuit board 34 and a battery 35 disposed in the housing 31 . The first light source 32 is disposed on the circuit board 34 . The battery 35 , the circuit board 34 , and the first light source 32 are electrically connected in sequence.

[0054] It can be understood that the battery supplies power to the first light source through the circuit board.

[0055] Furthermore, the light emitting module 30 further includes a solar panel 311 . The solar panel 311 is disposed outside the housing 31 , facing upward, and is electrically connected to the circuit board 34 .

[0056] It can be understood that the solar panel can absorb external light to charge the battery, so that the floating projection decorative light does not need to replace the battery or manually charge, which provides convenience for use.

[0057] Furthermore, the light emitting module 30 further includes a sensing device 37 disposed on the circuit board 34 . A through hole 312 is provided on the housing 31 and is disposed upward. The positions of the sensing device 37 correspond to those of the through hole 312 .

[0058] It can be understood that the sensing device can receive external light changes through the through hole. When the external light is too dark, the sensing device can transmit a signal to the main board, so that the main board powers on all light sources. When the external light is too bright, the sensing device can transmit a signal to the main board, so that the main board cuts off the power to all light sources. In this way, the floating projection decorative lamp automatically turns off the light source during the day and automatically turns on the light source at night, which is more convenient for users to use.

[0059] Furthermore, the light emitting module 30 further includes a light-distributing paper 38 , and the light-distributing paper 38 covers the through hole 312 .

[0060] It can be understood that the light-distributing paper covering the through hole can make the light covered on the light-distributing paper project more evenly onto the sensing device, and can protect the sensing device in the through hole from being damaged.

[0061] Furthermore, the housing 20 is made of a light-transmitting material.

[0062] It can be understood that the outer shell is made of a light-transmitting material, and the solar panels installed inside can receive light to charge the floating projection decorative lights.

[0063] Furthermore, the mapping portion 22 includes a bottom shell 221 , and the transmissive pattern 23 is disposed on the bottom shell 221 .

[0064] It can be understood that in some embodiments, no transmissive pattern is provided on the bottom cover.

[0065] Furthermore, the bottom shell 221 is made of PVC.

[0066] It is understandable that PVC material has a wide range of uses, so the cost is low, and PVC material has the characteristics of high strength and corrosion resistance. The bottom shell is in contact with the water surface for a long time, and the use of PVC material for the bottom shell can increase the service life of the bottom shell.

[0067] Furthermore, the projection pattern 23 is screen-printed on the bottom shell 221 .

[0068] Understandably, the cost of silk screen printing is lower, which can further save costs.

[0069] Furthermore, the shape of the transmission pattern 23 is one or more of an animal shape, a plant shape, a geometric shape, and an irregular shape.

[0070] It is understandable that the transmission pattern can be of various styles. For example, if the transmission pattern is in the shape of a flamingo, the floating projection decorative light can project the pattern of a flamingo in the water, thereby increasing the fun and providing users with more choices.

[0071] Furthermore, the floating projection decorative lamp 10 further includes a protective cover 40 . The protective cover 40 is disposed in the second accommodating space 25 and above the transmissive pattern 23 .

[0072] It can be understood that the protective cover is arranged above the transmissive pattern to protect the transmissive pattern from being crushed.

[0073] Furthermore, the protective cover 40 is made of transparent material.

[0074] It can be understood that using a transparent material for the protective cover can minimize the loss of light intensity.

[0075] Furthermore, the light emitting module 30 further includes a condenser 39 , which is connected to the light opening 33 . A plurality of transparent protrusions 391 are provided on the inner side wall of the condenser 39 .

[0076] In some embodiments, the light-emitting module further includes a focussing cover, and no transmissive pattern is provided on the mapping portion. The focussing cover is made of a transparent material, and the transparent protrusions provided on the inner wall of the focussing cover can converge light, thereby presenting light spots on the water surface after passing through the mapping portion.

[0077] Furthermore, the light emitting module 30 is detachably connected to the main body 21 .

[0078] refer to Figure 14 In the second embodiment, the mapping portion is detachably connected to the second accommodating space at the bottom of the main body portion, the outer shell and the housing are made of a harder plastic material, and the floating projection decorative lamp can float on the water without inflation.

[0079] Furthermore, the light emitting module 30 further includes a second light source 321 . The second light source 321 is electrically connected to the circuit board 34 , and the second light source 321 is disposed toward the main body 21 .

[0080] It can be understood that the second light source is arranged toward the upper main body portion, so the second light source can illuminate the upper portion of the floating projection decorative lamp, providing a better experience for users.

[0081] Furthermore, a first light-transmitting cover 314 is provided on a side wall of the housing 31 facing the main body 21, and the position of the first light-transmitting cover 314 corresponds to the position of the second light source 321; a second light-transmitting cover 313 is provided on a side wall of the housing 31 facing away from the main body 21, and the position of the second light-transmitting cover 313 corresponds to the position of the first light source 32.

[0082] It can be understood that the first light-transmitting cover is made of a transparent material, which allows the light emitted by the second light source to pass through and illuminate the upper part, and the second light-transmitting cover is made of a transparent material, which allows the light emitted by the first light source to pass through and illuminate the water.

[0083] Furthermore, the floating projection decorative lamp 10 further includes an air filling port 50 , which is disposed on the side wall of the main body 21 ; the floating projection decorative lamp 10 further includes a suspension 60 , which is disposed on the top of the floating projection decorative lamp 10 .
