Description

Technical Field

[0001] The present application relates to the application fields of LED lamp lighting technology and NFC technology, and in particular to an LED light string with NFC function. Background Art

[0002] LED is a light-emitting diode. LED light strings are made up of a certain number of LED lamp beads connected in series. They can be used for decorative scenes. For example, they can be placed on flowers or gifts to set off the flowers and gifts to a certain extent.

[0003] Existing LED light strings used with flowers and gifts are powered by a small white box battery compartment, typically containing three LR44 1.5V button cells. However, light strings used with flowers and gifts are typically disposable, requiring only 12-24 hours of continuous illumination. Therefore, two 3V batteries are sufficient. The small white box is also unsightly and stands out among gifts and flowers, leaving much room for improvement. Utility Model Content

[0004] The utility model provides a heart-shaped LED light string with an NFC function. Two button batteries are arranged in the heart-shaped battery compartment, which can save resources.

[0005] The utility model adopts the following technical solutions:

[0006] An LED light string includes an LED lamp string and a battery box, and also includes an NFC chip. The battery box is heart-shaped and is formed by an upper box and a lower box that are clamped together. A fixing seat is provided in the lower box. Two button batteries are fixed by the battery seat to form an upper and lower series connection and contact with PCB board contacts. The PCB board is conductively connected to the battery. A chip that controls the flashing and constant lighting of the LED lamp string is provided on the PCB board. The LED lamp string is welded to the PCB board. The NFC chip is fitted on the inner wall of the upper box of the battery box.

[0007] A battery insulating sheet is arranged between the two button batteries. The battery insulating sheet includes an insertion portion and a handle portion. The insertion portion and the handle portion are integrally formed. The insulating sheet is passed through or inserted into the hole between the upper box and the lower box through the handle portion.

[0008] The insert is heart-shaped and the handle is feather-shaped.

[0009] A fixing post is provided in the upper box, and a fixing groove is provided in the lower box. The fixing post is inserted into the fixing groove and matched with the fixing groove. Through the tight match between the fixing post and the fixing groove, the upper box and the lower box are fixed as one.

[0010] The heart-shaped battery box is beautiful and unobtrusive, making it a perfect match for flower gifting. The original three 1.5V button batteries are replaced with two, ensuring maximum usability while saving resources and avoiding excessive environmental impact.

[0011] This utility model uses an NFC chip, which can be programmed with text, images, audio, video, or web pages to convey emotional content. When a mobile phone with NFC software or an NFC applet installed touches the battery case, the NFC chip senses the pre-written text, image, audio, video, or web page and reads it. When this utility model is used in scenarios such as flowers and gifts, the recipient can touch the heart-shaped battery case with their phone to sense the NFC chip, thereby conveying emotional content.

[0020] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0021] Example

[0022] like Figure 1-4As shown, an LED light string includes an LED string 1, a battery box 2, and an NFC chip 6. The battery box 2 is heart-shaped and consists of an upper box 21 and a lower box 22 that snap together. Two button batteries are secured by a battery holder 4, forming a vertical series connection and contacting the PCB board contacts. PCB 71 is connected to the battery contacts. PCB 71 is a conventional PCB used in light strings and is equipped with a chip 72 that controls the LED string's flashing and steady lighting. The LED string is soldered to the PCB with the chip, forming a power circuit. Chip 72 on PCB 71 is a commercially available product, such as a bonding chip or other common light string control chip.

[0023] An NFC chip 6 is provided above the button battery and is attached to the inner wall of the battery box upper case 21. The NFC chip 6 does not require power supply.

[0024] like Figure 1 、 Figure 2 and Figure 7 As shown, a movable battery insulating sheet 5 is provided between the button battery 31 and the button battery 32, and the battery insulating sheet 5 is inserted or passed through the hole 8 between the upper box 21 and the lower box 22. Figure 5 As shown, the battery insulating sheet 5 includes an insert portion 51 and a handle portion 52. The insert portion 51 and the handle portion 52 are integrally formed. The insert portion 51 is larger than or equal to the negative terminal of the button battery. The insert portion 51 of the battery insulating sheet 5 is heart-shaped, and the handle portion 52 is arrow-shaped.

[0025] like Figure 2 、 Figure 6 and Figure 7 As shown, the handle portion 52 is inserted or extended between the upper box 21 and the lower box 22. By applying force to the handle portion 52 of the battery insulating sheet, the battery insulating sheet can be pulled out, and the LED lamp string can be constantly lit or flashing. If you need to turn off the light, just insert the battery insulating sheet 5.

[0026] A fixing post 211 is provided in the upper box 21, and a fixing groove 221 is provided in the lower box 22. The fixing post 211 is inserted into and matched with the fixing groove 221. By the tight fit between the fixing post 211 and the fixing groove 221, the upper box 21 and the lower box 22 are fixed as one.

[0027] NFC chips and supporting software are existing technologies. The present invention is not intended to protect the NFC chips and supporting software themselves, but to protect the LED light strings with the NFC chips. NFC chips are commercially available products.

[0028] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
