Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically to a USB light lamp. Background Technology

[0002] Most LED lights such as nightlights, ambient lights, and reading lights on the market are high-voltage products. They are connected to the mains power interface and then stepped down by a driver to achieve a safe driving voltage to light up the product. These light sources usually have a certain size, which is inconvenient to carry when going out. Their application range is also limited by the interface and voltage.

[0003] There are currently some LED portable lights, camping lights, night lights and other LED lamps on the market that use USB interfaces for power supply. They can use the interfaces of devices such as power banks, laptops and mobile phone chargers, and have flexible application scenarios. However, they generally have problems such as uneven and continuous light, uneven brightness and dark areas, and obvious light spots. In addition, these devices still have a certain size, which makes it difficult to meet some application scenarios with high requirements for space and weight, such as miniature lighting devices and wearable devices.

[0005] The technical solution of this utility model is: a USB light lamp, including a housing, a USB interface fixed to one end of the housing, and a light-emitting component fixedly connected to the other end. The light-emitting component is a flexible LED filament with 360° light emission. A circuit board is disposed inside the housing. The input end of the circuit board is connected to the USB interface, and the output end of the circuit board is connected to the power line of the flexible LED filament. The circuit board transforms the voltage supplied by the USB interface and supplies it to the flexible LED filament. In the above technical solution, the USB interface has a wide range of power sources and is not limited by traditional high-voltage interfaces, making its application scenarios flexible. Integrating the circuit board into the housing of the USB interface can minimize the size. The flexible LED filament is lightweight, easy to carry, and can withstand certain pressure and impact without affecting the performance of the product.

[0006] In a further embodiment, the housing is equipped with a switch for controlling the output of the circuit board. In the above technical solution, the output of the circuit board can be controlled by the action of the switch, thereby enabling the power supply to the LED flexible filament to be switched on or off, or the lighting to be changed.

[0007] In a further embodiment, the positive and negative electrodes of the LED flexible filament are arranged at the same end. In this technical solution, arranging the positive and negative electrodes at the same end facilitates connection to the circuit board, and the other end of the LED flexible filament can be freely arranged without needing to be wound back onto the circuit board for connection.

[0008] In a further embodiment, the LED flexible filament emits light in either a single color or RGB colors. In the above technical solutions, the emitted light color can be selected according to the application scenario; RGB colors can achieve a multi-colored effect and create ambient lighting.

[0009] In a further embodiment, the USB interface is either a USB-A interface or a USB-C interface. In the above embodiments, USB-A and USB-C are universal standard interfaces, compact and lightweight, and offer good device compatibility.

[0010] In a further embodiment, the outer wall of the LED flexible filament is provided with a sheath or a braided layer. By adding a sheath or braided layer, a wider variety of appearances and lighting effects can be created.

[0011] In a further embodiment, the wavelength of the light emitted by the flexible LED filament is 590nm. This embodiment utilizes the sensitivity of mosquitoes to light at a specific wavelength of 590nm to more effectively repel them.

[0012] In a further embodiment, a magnetic component is provided at the end of the LED flexible filament furthest from the USB interface. In this embodiment, the magnetic component can attract metal components such as iron, facilitating the hanging of the light fixture or the straightening of the LED flexible filament.

[0013] In a further embodiment, the diameter of the LED flexible filament is ≥0.5mm.

[0014] In a further embodiment, a metal wire extending along the length of the LED flexible filament is embedded within it, or a self-adhesive backing is provided on the surface of the LED flexible filament. In the above embodiments, the metal wire has a certain shaping ability, which allows the LED flexible filament to maintain the desired shape after bending, and the self-adhesive backing can adhere the LED flexible filament to other objects, while also having a certain shaping ability.

[0015] This utility model has the following advantages compared with the prior art:

[0016] (1) This utility model supports universal standard interfaces such as USB-A and USB-C (Type-C), is small and lightweight, has good device compatibility, is not limited by traditional high-voltage interfaces, and USB-C supports reversible insertion, which greatly improves the convenience of use and makes it convenient to use in various scenarios such as indoor and outdoor, such as night lights and camping.

[0018] (3) The flexible LED filament emits light in 360°, resulting in better light uniformity, reducing uneven brightness and improving lighting quality;

[0019] (4) The mosquito repellent effect is highly targeted. By utilizing the sensitivity of mosquitoes to specific wavelengths of light, it can more effectively repel mosquitoes.

[0031] Example 1

[0032] like Figure 1 As shown, the USB light provided in this embodiment is powered by a USB interface, thus eliminating 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 housing 2 is fixed to the tail end of the USB interface, and a light-emitting component is fixed to the tail end of the housing 2.

[0033] In this embodiment, the light-emitting component uses a flexible LED filament 3 with 360° light emission. The substrate of the flexible LED filament 3 is a flexible substrate 3.1. The LED chip 3.2 is fixed on the chip and connected by wires. The positive and negative electrodes are located at the same end of the flexible substrate 3.1 for easy connection. The flexible substrate 3.1 and the LED chip 3.2 are covered by an adhesive layer 3.3, which can guide light to achieve 360° light emission, resulting in better light uniformity, reducing uneven brightness, and improving lighting quality. The flexible LED filament has good flexibility and its shape can be changed according to actual usage needs. Drops and slight compression during normal use will not affect the performance of the product. By adding a sheath or braided layer, and using partially transparent or semi-transparent braided filaments, different light emission effects can be achieved, creating a more diverse range of appearances and lighting effects.

[0034] like Figure 2As shown, in this embodiment, a circuit board 4 is disposed inside the housing 2. The input terminal of the circuit board 4 is connected to the power pins (VCC, GND) of the USB interface, and the output terminal is connected to the positive and negative terminals of the LED flexible filament. The USB interface is typically connected to +5V or a higher voltage, while the voltage of the LED flexible filament is typically +3V. The circuit board 4 has a voltage transformation 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 uses a different voltage, the circuit board 4 can also step down / step up the voltage to the corresponding voltage to supply the LED flexible filament for operation.

[0035] The housing 2 is equipped with a switch for controlling the output of the circuit board 4. Control signals, such as on / off signals, can be input to the circuit board 4 via the switch to control the light on and off. Considering the limited installation space, a touch-sensitive switch is recommended. The LED flexible filament emits monochromatic or RGB light. In this embodiment, the LED flexible filament can contain one LED chip circuit or multiple circuits. The number of times the switch is pressed controls the switching of the circuits, thus changing the emitted light color.

[0036] In this embodiment, the wavelength 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, ambient lighting, etc., or it can utilize the sensitivity of mosquitoes to specific wavelengths of light, using a 590nm wavelength to make mosquitoes flee in the opposite direction, thus more effectively repelling them. While its mosquito-repelling range is relatively limited, it is sufficient for personal or small-scale use. Furthermore, it eliminates the risk of fire due to the absence of open flame, ensuring high safety and low chemical pollution risk. Its gentle and safe characteristics make it suitable for a wide range of people. Whether indoors or outdoors, such as in bedrooms, living rooms, tents, parks, or the wilderness, any device with a USB-A power supply can function as a mosquito repellent.

[0037] In this embodiment, the diameter of the flexible LED filament is ≥0.5mm. Its small size and lightweight design allow it to easily fit into a backpack, pocket, or even be attached to a keychain, making it convenient to carry without adding excessive burden to travel. Furthermore, 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 products, such as wearable devices and miniature lighting devices.

[0038] In this embodiment, when it is necessary to use LED flexible filaments to create shapes, a metal wire extending along its length can be embedded in the LED flexible filament, or a self-adhesive backing can be provided on the surface of the LED flexible filament to achieve the shaping function.

[0039] Example 2

[0040] like Figure 3As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, a magnetic component 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 attracted to metal materials such as iron using its magnetism, adding a support point during shaping, and can also be used to suspend light fixtures or straighten the LED flexible filament.

[0041] Example 3

[0042] like Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the USB interface used is a USB-C interface (Type-C).

[0043] Example 4

[0044] like Figure 5 As shown, the difference between this embodiment and embodiment 2 is that the USB interface used is a USB-C interface 1.2.

[0045] The above description is merely a preferred embodiment of this utility model. For those skilled in the art, various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
