[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] In the description of the present invention, it is necessary to understand that the orientation or position relationship indicated by terms such as "longitudinal", "lateral", "upper", "lower", "vertical", "horizontal", "top", "bottom", "one end", etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] In the present invention, unless otherwise clearly specified and limited, terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be fixedly connected, detachably connected, or integrated; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Example 1 like Figure 1 As shown, the USB light provided in this embodiment is powered by a USB interface, thereby getting rid of the dependence on a high-voltage interface (mains power interface). There are various forms of USB interfaces. In this embodiment, the commonly used USB-A interface 1.1 is selected. In this embodiment, a shell 2 is fixed to the tail end of the USB interface, and a light-emitting component is fixed to the tail end of the shell 2.

[0028] In this embodiment, the light-emitting component adopts a 360° light-emitting LED flexible filament 3, the substrate of the LED flexible filament 3 is a flexible substrate 3.1, the LED chip 3.2 is fixed on the chip and connected by a wire, the positive and negative electrodes are located at the same end of the flexible substrate 3.1 for easy connection, the outside of the flexible substrate 3.1 and the LED chip 3.2 is covered by a rubber coating 3.3, and the rubber coating 3.3 can guide light to achieve 360° light emission, better light uniformity, reduce the phenomenon of uneven light and dark, and improve the lighting quality. The LED flexible filament has good flexibility and can change its shape according to actual use requirements. Falling and slight squeezing during normal use will not affect the performance of the product. By adding a sheath or a braided layer and using partially transparent or translucent braided wire to achieve different light emission effects, a more diverse appearance and lighting effects can be created.

[0029] like Figure 2As shown, in this embodiment, a circuit board 4 is arranged in the housing 2, and the input end of the circuit board 4 is connected to the power pin (VCC, GND) of the USB interface, and the output end is connected to the positive and negative electrodes of the LED flexible filament. The USB interface is usually connected to a voltage of +5V or higher, while the voltage of the LED flexible filament is usually +3V. The circuit board 4 has a voltage conversion function (step-down / step-up), which can step down the +5V to +3V to supply the LED flexible filament for operation. Obviously, if the LED flexible filament used is other voltages, the circuit board 4 can also step down / step up to the corresponding voltage to supply the LED flexible filament for operation.

[0030] The housing 2 is provided with a switch for controlling the output of the circuit board 4. A control signal, such as an on / off signal, can be input to the circuit board 4 through the switch to control turning the light on and off. Considering the small installation space, a touch switch is recommended. The LED flexible filament emits light in a single color or RGB color. In this embodiment, the LED flexible filament may contain one LED chip circuit or multiple circuits. The switching of the circuits can be controlled by the number of times the switch is pressed, and the color of the light output can be switched.

[0031] In this embodiment, the wavelength of the light of the LED flexible filament can be determined according to the application scenario. It can be a commonly used lighting band to meet the needs of reading, night lights, atmosphere lights, etc. It can also use the sensitivity of mosquitoes to light of a specific wavelength. The light wave of the 590nm band can make mosquitoes flee in the opposite direction, which can more effectively repel mosquitoes and has a better mosquito repellent effect. Although its mosquito repellent range is relatively limited, it is sufficient for personal or small-scale use, and there is no open flame, which avoids the risk of fire, has high safety, and has a low risk of chemical pollution. Its mild and safe characteristics make it suitable for a wide range of people. Whether indoors or outdoors, such as bedrooms, living rooms, tents, parks, and the wild, as long as the device is powered by a USB-A interface, it can play a mosquito repellent role.

[0032] In this embodiment, the diameter of the LED flexible filament is ≥0.5 mm. It is small and light, and can be easily put into a backpack, pocket or even hung on a key chain, which is convenient to carry without adding too much burden to travel. In addition, due to its small diameter and good flexibility, it can be integrated with other electronic components or materials to improve the integration and performance of the product, such as wearable devices and micro lighting equipment.

[0033] In this embodiment, when the LED flexible filament needs to be shaped, a metal wire extending along the length direction of the LED flexible filament can be embedded in the LED flexible filament, or a self-adhesive adhesive can be provided on the surface of the LED flexible filament to achieve the shaping function.

[0034] Example 2 like Figure 3As shown, the difference between this embodiment and embodiment 1 is that in this embodiment, a magnetic member 5, such as a magnetic bead, is provided at the end of the LED flexible filament away from the USB interface. The magnetic bead can be adsorbed onto metal materials such as iron to add a support point during modeling, and can also be used to suspend a light lamp or straighten the LED flexible filament.

[0035] Example 3 like Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the USB interface adopts a USB-C interface (Type-C).

[0036] Example 4 like Figure 5 As shown, the difference between this embodiment and embodiment 2 is that the USB interface adopts the USB-C interface 1.2.

[0037] The above is only a preferred embodiment of the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
