[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention. Obviously, the embodiments described in the present invention are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] Embodiment 1: The specific structure of the present invention is as follows:

[0028] Please refer to the attached Figure 1-6 , a USB atmosphere lamp of the present invention includes a flexible strip 101, a bendable LED light strip, and a light-shielding rubber coating layer 103.

[0029] The flexible strip 101 has a placement groove for the bendable LED light strip. One edge of the flexible strip 101 in the length direction is set as a light guide edge 104, and the light guide edge 104 can conduct light. The bendable LED light strip is arranged in the placement groove for the bendable LED light strip. A plurality of parallel-connected lamp beads are arranged on the bendable LED light strip, and each lamp bead is internally provided with an IC and a pad is arranged at every other lamp bead. The light emitted by the bendable LED light strip can be conducted to the light guide edge 104. The light-shielding rubber coating layer 103 is coated on the flexible strip 101 to cover the bendable LED light strip, and only the light guide edge 104 is visible. The light-shielding rubber coating layer 103 is set to be black. The width of the light guide edge 104 ≤ 1 mm.

[0030] Such as Figure 1-4As shown, specifically, the installation process of the USB atmosphere light of the present invention is as follows: patch the circuit board according to the customized circuit board, and after the patch is completed, connect the soldering wire to the first BMW head 106, then put it into the LED light strip placement slot on the flexible belt 101 and wrap it with a light-shielding rubber layer 103, so that the light source can stably and softly emit colorful lights from the 1mm wide light guide edge 104. Finally, lead out the power line and signal line to the second BMW head, and then connect the second BMW head to the USB plug 105. The USB plug 105 can be powered by plugging into the USB in the car or on the computer, and it can be plugged in and light up. Blow the heat shrink tubing 102 at the outlet position of the flexible LED light strip. The heat shrink tubing 102 insulation plays a protective role and can also help manage the wiring harness. The USB atmosphere light of the present invention is a narrow style, and the wiring of the circuit diagram is simple and efficient. Although it is narrow, the wiring line width is exquisitely designed and can withstand large currents without burning the board. The specific width is 2.6mm, and the light guide strip, which is 7.8mm high and 1.3mm thick, allows it to blend seamlessly into the car, achieving a hidden function. Each lamp bead has a built-in IC, and a solder pad is provided for each lamp bead. Even if a lamp bead is cut out, it can still light up. Therefore, this USB ambient light can be cut to adjust the length at will, and the length can be customized according to user needs.

[0031] like Figure 5-6 The IC model is MT1815. The signal input terminal DIN of the first IC is connected to the controller, and its signal output terminal is connected to the signal input terminal DIN of the next IC. The signal output terminal DOUT of the next IC is connected to the signal input terminal DIN of the third IC, and so on, to realize the controller's control of each lamp bead.

[0032] Any lamp bead is connected to a capacitor, the first end of the capacitor is connected to the power input terminal of the IC, and the second end of the capacitor is connected to the ground terminal of the IC. The capacitor is a 104 capacitor.

[0033] Each lamp bead is equipped with RGB three-color LED. Figure 6 As shown, the positive terminal of the RGB tri-color LED is connected to the power supply terminal, and the negative terminal thereof is connected to the OUTR pin of the IC, the OUTG pin of the IC, and the OUTB pin of the IC respectively.

[0034] The IC of the present utility model adopts a single-wire communication mode and sends signals in the form of return-to-zero codes. After power-on reset, the IC receives the data from the DIN terminal. After receiving 24 bits, the DOUT port starts to forward the data to provide input data for the next IC. Before forwarding, the DOUT port is pulled low all the time. At this time, the IC will not receive new data. The three PWM output ports of OUTR, OUTG, and OUTB of the IC send signals with corresponding different duty cycles according to the received 24-bit data, and the signal frequency is 4 kHz. If the input signal at the DIN terminal is a RESET signal, the IC will send the received data for display, and the IC will receive new data again after the signal ends. After receiving the first 24-bit data, it forwards the data through the DOUT port. Before receiving the RESET code, the original outputs of the OUTR, OUTG, and OUTB pins remain unchanged. When receiving a RESET code with a low level of more than 80 μs, the IC outputs the pulse width of the just-received 24-bit PWM data to the OUTR, OUTG, and OUTB pins.

[0035] Embodiment 2:

[0036] The USB atmosphere light of the present utility model can be applied to the center console of an automobile. The thickness and width of the automobile atmosphere light are 7.8 ± 0.05 mm and 1.7 ± 0.05 mm respectively. It is easy to install and can be installed as long as there is a gap without damaging the vehicle. It can be pasted on the center console of the automobile or embedded in the automobile, perfectly hidden without affecting the appearance of the automobile. The USB atmosphere light of the present utility model can have the colors flowing, multiple colors, and multiple modes that can be switched. The brightness can be adjusted conveniently, and the light is soft and not dazzling, protecting the eyes. The USB atmosphere light of the present utility model is provided with APP Bluetooth connection + remote control, which can present a more dynamic and rich lighting effect, enhancing the user experience. The lamp beads have built-in ICs and can be cut one by one. The extra length can be freely cut without affecting the use. The USB interface makes it light up immediately after installation, and it can be used for 99% of vehicle models and can be customized in length according to user needs.

[0037] In summary, the USB atmosphere light of the present utility model is an atmosphere light composed of a flexible strip and a bendable LED light strip, which can be bent and is convenient for installation. The bendable LED light strip of the present utility model is provided with multiple parallel lamp beads, each lamp bead is internally provided with an IC, and a pad is set at every other lamp bead. The bendable LED light strip can be arbitrarily cut in length, and users can DIY the atmosphere light according to their needs. The bendable LED light strip of the present utility model only leaves a light guide edge less than 1 mm wide as the light-emitting edge, and the rest is hidden in the accessories, making the accessories simple.

[0038] The above are only the preferred embodiments of the present utility model, and do not thus limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
