Description

Technical Field

[0001] The utility model relates to a decorative ball, in particular to a foam photosensitive Christmas ball. Background Art

[0002] During the Christmas season, foam Christmas balls are a widely used holiday decoration and are very popular among users. However, traditional foam Christmas balls are mostly solid structures, lacking internal cavities or lighting components, and cannot be installed with light-emitting elements such as LEDs. This design results in the Christmas balls being unable to emit light at night, making it difficult to create a festive atmosphere. At the same time, due to the limitations of the foam material itself, if you try to use a high-voltage power supply (such as 110V or 220V) to connect lighting equipment through wires, the installation process not only increases the wiring workload, but also faces potential safety hazards such as waterproofing and leakage. Therefore, existing foam Christmas balls have major defects in providing nighttime decorative effects.

[0003] While some small LED lamps are currently available for holiday decorations, they often rely on wired connections and high-voltage power supplies, making them difficult to integrate with foam Christmas balls. Furthermore, these solutions often lack automatic light-sensing control, meaning they can't automatically turn the lights on and off based on ambient light levels. This results in high energy consumption and negatively impacts energy conservation and environmental protection. While battery-powered portable lighting devices can address some of the convenience issues, they often require manual switching, lack intelligent light-sensing control, and are difficult to operate and not suitable for extended use. Summary of the Invention

[0004] In order to solve the above problems, the utility model provides a foam photosensitive Christmas ball, which can be equipped with a low-voltage power supply lighting component inside the foam Christmas ball. It also has a photosensitive automatic switch function to automatically light up at night and automatically turn off during the day, making it easy to disassemble and separate.

[0005] The utility model is realized through the following technical solutions: a foam photosensitive Christmas ball, comprising:

[0006] A foam sphere, wherein a hollow cavity is formed inside the foam sphere and a lighting assembly is installed therein for lighting the foam sphere;

[0007] A lamp holder, which is detachably mounted on one side of the foam sphere, has a mainboard and a battery installed therein, is in electrical contact with the lighting assembly, and the battery is connected to the mainboard;

[0008] A photosensitive chip is installed on the mainboard, and the photosensitive chip is used to detect the intensity of external light and control the switch of the lighting component through the mainboard.

[0010] As a preferred technical solution, a conductive contact is provided at the bottom of the mainboard corresponding to the conductive end of the lighting assembly, and the conductive contact is in conductive contact with the conductive end of the lighting assembly.

[0011] As a preferred technical solution, the lighting assembly includes a lamp post and a light strip installed on the lamp post. The interior of the lamp post is hollow for laying out the power connection line. A conductive column is set on the top of the lamp post. When the foam sphere and the lamp head are assembled with each other, the conductive column is in conductive contact with the conductive contact.

[0012] As a preferred technical solution, a plurality of magnetic blocks are provided at the bottom of the lamp holder, a metal block is embedded in the foam sphere, and the lamp holder and the foam sphere are magnetically attracted.

[0013] As a preferred technical solution, the magnetic blocks are arranged around the lamp holder in a circle, and each magnetic block corresponds to a metal block.

[0015] The beneficial effects of the utility model are as follows: the foam photosensitive Christmas ball of the utility model can automatically light up at night and automatically go out during the day by designing a built-in lighting component and an automatic photosensitive control circuit, which greatly enhances the festive atmosphere of the Christmas ball. The design adopts a button battery low-voltage power supply, eliminating complicated wiring and high-voltage power supply devices, avoiding leakage and waterproof problems, and is safe and reliable.

[0016] At the same time, the foam Christmas ball has a structure that is easy to assemble and disassemble. Users can replace the battery with simple operations, which greatly improves convenience and service life. The device can be stably fixed in the foam Christmas ball through a magnetic connection or a snap structure, making the electrical connection between the lamp head and the foam ball more secure.

It does not require manual operation and is more convenient and environmentally friendly to use. It not only increases the use scenarios and visual effects of Christmas decorations, but also provides users with a new experience of safety, ease of use and energy saving.

[0025] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0026] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0027] like Figure 1-Figure 4 As shown, a foam Christmas ball with a light-sensitive structure is designed. By adding a hollow cavity 10 within the foam ball body 1 and housing a lighting assembly, the ball automatically illuminates at night to enhance the festive atmosphere. The foam ball body 1 is a circular structure with a hollow cavity 10 formed inside for mounting the lighting assembly.

[0028] The lighting assembly includes a lamp post 9 and a light strip 11 fixed on the lamp post 9. The lamp post 9 is hollow to accommodate the layout of the power connection line, so that the light strip 11 can be stably installed inside the foam sphere 1, so that the lighting assembly can evenly distribute light inside the foam sphere 1, thereby providing a good lighting effect.

[0029] A removable lamp holder 2 is mounted on one side of the foam Christmas ball, connected to the foam sphere 1 via a magnetic block 12 and a metal block. The lamp holder 2 houses a motherboard 5 and a battery, which is connected to the motherboard 5 via a circuit to provide low-voltage power to the Christmas ball's lighting components.

[0030] The battery, a button cell 6, is installed in a battery compartment inside the lamp base 2. The lamp base 2 has a slot 3 for the button cell 6. An insulating sheet is inserted into the slot 3 to disconnect the button cell 6 from the circuit. When in use, the user can simply remove the insulating sheet to connect the button cell 6 to the circuit, easily and conveniently activating the Christmas ball's lighting function.

[0031] The mainboard 5 of the lamp head 2 is equipped with a photosensitive chip that detects the intensity of external light. When the light is low, the photosensitive chip controls the lighting assembly through the mainboard 5, automatically illuminating the LED light strip 11. Conversely, when the light is sufficient, the LED light strip 11 automatically turns off to save power. This automatic light-sensitive switch design eliminates the need for manual operation by the user, ensuring energy savings.

[0032] like Figure 3 As shown, the bottom of the lamp holder 2 is equipped with multiple magnetic blocks 12, which form a magnetic connection with the metal blocks on the foam sphere 1. The magnetic blocks 12 are arranged in a circle around the lamp holder 2, with each magnetic block 12 corresponding to a metal block on the foam sphere 1. This magnetic connection structure ensures that the lamp holder 2 is firmly fixed to the foam sphere 1, while also allowing for easy removal for battery replacement and maintenance of internal components. A hanging strap 4 is installed on the top of the lamp holder 2, allowing users to easily hang the foam Christmas ball on tree branches, windows, and other locations.

[0033] The bottom of the foam sphere 1 is also designed with a wiring hole 13, which can connect the Christmas balls up and down to make them hang in series and use them as a light string. Of course, you can also use only the top hanging belt 4 and use it alone.

[0034] When the foam sphere 1 is connected to the lamp holder 2, the conductive column 8 on the top of the lamp post 9 will contact the conductive contact 7 at the bottom of the main board 5 to conduct electricity, so that the current is transferred from the battery in the lamp holder 2 to the LED light strip 11 of the lighting assembly, ensuring the consistency of power supply and lighting effect.

[0035] like Figure 4 In the circuit shown in Figure 1, R1 and R2 are voltage-divider resistors used to detect ambient light intensity. When the light is strong (such as during the day), the photosensitive chip detects the light signal. The voltage between R1 and R2 controls the base voltage of transistor T1, turning it on. When T1 turns on, its collector potential drops, causing the base voltage of T2 to drop, turning T2 off and turning the LED off.

[0036] When the external light becomes dim (such as at night), the photosensitive chip detects a lower light intensity. The voltage divider between R1 and R2 reduces the base voltage of T1, causing T1 to be cut off. At this time, the base potential of T2 increases, turning on T2, causing the LED to glow when powered, thereby lighting up the foam Christmas ball.

[0037] In summary, this circuit automatically controls the conduction state of T1 and T2 by detecting the intensity of ambient light, thereby realizing automatic switching of the LED light. The LED is off during the day and automatically lights up at night, achieving the purpose of energy saving and intelligent control.

[0038] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
