Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and in particular to an LED neon light with an auxiliary power supply interface. Background Technology

[0002] Light-emitting diode (LED) lighting technology is increasingly widely used in modern life. Flexible LED light strips, based on flexible printed circuit boards (FPCs), have been widely applied in various fields such as interior and exterior decoration, advertising signage, and creative design due to their flexibility and bendability. With the increasing demand for long-distance continuous lighting in commercial spaces and building facades, the application length of flexible LED light strips continues to grow. However, the resulting technical challenges are gradually emerging.

[0003] Because the copper foil thickness of FPC flexible circuit boards is typically 5-35μm, the cross-sectional area of ​​the conductors is limited. When the connection length exceeds a certain threshold, the IR voltage drop caused by the friction loss becomes increasingly prominent. In practical applications, it is common to see a situation where the voltage at the beginning of a neon light is 12V, but drops to 10.5V at the end, resulting in a brightness difference of more than 15% between the beginning and end, severely affecting the consistency and aesthetics of the lighting effect. Currently, the industry generally adopts the method of limiting the maximum usable length of products, such as controlling the length of a single neon light to within 5 meters, in order to alleviate voltage attenuation. However, this creates a sharp contradiction with the need for continuous lighting of tens of meters in large-scale projects.

[0004] Therefore, how to solve the voltage attenuation problem during long-distance lighting, while simplifying the on-site processing procedures after cutting and improving installation efficiency and structural reliability, has become a technical bottleneck that urgently needs to be overcome in the field of LED neon lights. Utility Model Content

[0035] Example 1

[0036] like Figures 1 to 9 As shown, this utility model provides an LED neon light with an auxiliary power supply interface, including a lamp housing 1, a white light-shielding silicone layer 2, a transparent silicone layer 3, an LED light strip 4, a pre-set soldering wire 5, and an electrical connection wire 6.

[0037] The lamp housing 1 is a long, rectangular hemispherical shape with a hollow internal cavity 101. It is made of colored, translucent silicone using an extrusion process. Colors include, but are not limited to, white, red, blue, green, orange, and yellow, and can be customized according to user needs. It has good flexibility and aesthetics. One end of the hemispherical arc surface of the lamp housing 1 has a through-hole 105 that runs horizontally through the light source, which helps to evenly diffuse the light and improve the lighting effect. It also saves materials and reduces costs. Clamping grooves 106 are provided on both sides of the lamp housing 1 for use with U-shaped fasteners (not shown in the figure). The U-shaped fasteners have limiting protrusions that fit the clamping grooves 106. The limiting protrusions are slidably fixed in the clamping grooves 106. The U-shaped fasteners can press the lamp housing 1 tightly to prevent the transparent silicone layer 3 installed in the cavity 101 from falling out, thus ensuring the stability of the structure.

[0038] The white light-shielding silicone layer 2 is made of white light-shielding silicone (which can be called a white light-shielding layer, diffusion silicone, or reflective silicone), and its main function is to block and reflect light. This layer wraps around the bottom or side of the transparent silicone layer and the LED light strip, and is U-shaped in overall shape. It can effectively prevent the light emitted by the LED from leaking to the back or side of the light strip, thereby improving luminous efficiency. The high reflectivity of the white material can reflect the downward or outward scattered light back to the front of the light strip, enhancing the brightness and uniformity of the light emitted from the front. At the same time, as part of the light strip housing, the white light-shielding silicone layer can enhance the overall mechanical strength and protect the internal FPC and LED components from external environmental influences such as water, dust, and mechanical damage. In this embodiment, the white light-shielding silicone layer 2 is U-shaped in overall shape, adheres to the outer surface of the transparent silicone layer, and is disposed inside the light housing 1, so that the light is scattered from the spherical side of the top of the light housing 1.

[0039] The transparent silicone layer 3, made of transparent silicone, wraps around the LED light strip. Its main function is to encapsulate and protect the internal structure of the LED light strip, while also softening and uniformly distributing the light, resulting in a flexible, durable, and high-brightness neon light strip. The transparent silicone layer can be manufactured using extrusion or injection molding processes to give the light strip various cross-sectional shapes such as round, flat, C-shaped, and U-shaped, while maintaining flexibility for easy shaping and installation. In this embodiment, the transparent silicone layer 3 encapsulates the LED light strip and is formed together with the white light-shielding silicone layer using an extrusion process.

[0040] The LED light strip 4 is a flexible light strip that combines LEDs with a flexible printed circuit board (FPC), making it bendable, cuttable, and easy to install, adaptable to different installation environments. The LED light strip 4 includes an FPC flexible circuit board and LEDs integrated thereon. Several pre-set bonding wires 5 are provided in the middle of the light strip for subsequent power connection to prevent voltage attenuation during long-distance lighting.

[0041] The transparent silicone layer 3 has an anti-color drift hole 102 (also known as a "light-shielding hole" or "optical isolation hole") at the position of the LED light strip and the transparent silicone layer 3 near the LED. Its function is to prevent color drift (color temperature drift / color deviation) problems caused by silicone sticking to the surface of the LED beads.

[0042] The white light-shielding silicone layer 2 is attached to part of the surface of the transparent silicone layer 3 according to the requirements of light shielding and reflection. The whole is U-shaped. The two are extruded together by extrusion process to wrap the LED light strip inside, forming a semi-finished product.

[0043] The lamp housing 1 encloses the white light-shielding silicone layer 2, the transparent silicone layer 3, and the LED light strip 4 within the internal receiving cavity 101, and is integrally formed using an extrusion process. Using the clamping groove 106 and the light-transmitting through hole 105 of the lamp housing 1, matching plugs 7 are installed at both ends to seal the internal receiving cavity 101 and prevent water, dust, etc. from entering.

[0044] The pre-installed solder wire 5 serves as an auxiliary power supply interface, including positive and negative terminals, and is electrically connected to the FPC flexible circuit board. To facilitate subsequent power connection, several lead-through holes 104 are provided on the lamp housing 1, the white light-shielding silicone layer 2, and the transparent silicone layer 3 for extending the pre-installed solder wire 5 (positive and negative terminals) and connecting to external electrical connections, thus solving the voltage attenuation problem during long-distance lighting. This structure supports parallel power supply via pre-installed solder wires on the LED strip surface, reducing voltage attenuation during long-distance lighting and improving power supply reliability and installation flexibility.

[0045] In actual production, the pre-set bonding wires 5 are arranged in a spaced array on the FPC flexible circuit board. The specific spacing is determined comprehensively based on parameters such as the neon light design length, the power of the LED strip 4, and the allowable voltage drop. For example, when the neon light design length is 10 meters and the LED strip 4 power is 10W per meter, the spacing of the pre-set bonding wires 5 can be set to 1 meter. Uniform arrangement can make the current transmission more uniform, reduce the IR voltage drop caused by friction loss, and ensure the brightness consistency of each part of the strip. When the LED strip 4, the pre-set bonding wires 5, and the external silicone material are extruded together, high-precision molds and positioning devices are used to ensure that the pre-set bonding wires 5 are accurately positioned in the predetermined array within the FPC flexible circuit board, ensuring structural stability and electrical connection reliability.

[0046] The LED light strip includes an electrical connection wire 6, which is electrically connected to the FPC flexible circuit board. The lamp housing 1, the white light-shielding silicone layer 2, and the transparent silicone layer 3 are provided with lead wire through holes 104 to facilitate the extension of the electrical connection wire 6, so as to realize the electrical connection between the FPC flexible circuit board and the external power supply or other electrical units.

[0047] The preferred LED is a white LED, but users can also choose LEDs with matching colors, such as red, green, blue, orange, and yellow, according to their color requirements.

[0048] Example 2

[0049] Based on Embodiment 1, the difference lies in the auxiliary power supply interface. The pre-set solder wire 5 and the corresponding lead through-hole 104 structure on the lamp housing 1, white light-shielding silicone layer 2, and transparent silicone layer 3 are removed. Instead, an FPC flexible circuit board is used to integrate positive and negative terminals (pre-set solder pads). Several positive and negative terminals can be set at intervals with reference to the position of the pre-set solder wire 5. The white light-shielding silicone layer and transparent silicone layer 3 have pre-set wiring grooves 103 on the back of the LED light strip to facilitate subsequent wiring, reserving space for wiring operations.

[0050] When it is necessary to solve the voltage attenuation problem of long-distance lighting, users can cut open the lamp housing 1, the white light-shielding silicone layer 2, and the transparent silicone layer 3 at the terminal block. The wires are then connected to the positive and negative terminals by plugging or soldering. After completing the electrical connection, the cut-open part is sealed with glue to ensure the overall protection level.

[0051] Compared to Embodiment 1, this embodiment uses an FPC flexible circuit board to integrate positive and negative terminals for the auxiliary power supply interface, eliminating the need for pre-set soldering wires and lead-through holes 104. Pre-set wiring grooves 103 in a white light-shielding silicone layer and a transparent silicone layer facilitate subsequent power connection operations. After the user completes the wiring or soldering connection and seals it, the voltage attenuation problem is effectively solved, improving the ease of installation and structural integrity of the light strip. In terms of manufacturing process, this solution reduces production steps, allowing users to connect as needed, improving product aesthetics and reducing overall costs.

[0052] Working Principle: The LED light strip is electrically connected to an external power supply via a pre-set auxiliary power supply interface. When the distance of the light strip is too long, causing voltage attenuation and uneven brightness, an external power supply (auxiliary power supply interface) can be connected at a low voltage location via a pre-set solder wire or positive and negative terminals to achieve parallel power supply, solving the problems of voltage attenuation and uneven brightness during long-distance transmission and ensuring consistent brightness throughout the entire light strip. After power-on, the white LEDs on the FPC flexible circuit board emit light. The light is softened and diffused by the transparent silicone layer before being emitted evenly. The white light-shielding silicone layer reflects some of the light back to the emitting surface, enhancing the brightness and uniformity of the front. The softened light passes through the colored transparent lamp housing, presenting different color light emission effects. The hemispherical lamp housing structure allows the light to overflow from the hemispherical surface, achieving multi-angle and wide-range illumination.

[0053] In summary, this utility model achieves uniform brightness and colorful light emission effects under long-distance illumination through a multi-point parallel power supply structure and a high-efficiency light mixing and emission structure. The structural design takes into account both optical performance and ease of installation.

[0054] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the specifications and drawings; the specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art; the machinery, parts, and equipment all adopt conventional models in the prior art; the control method is automatic control through a controller, and the control circuit can be implemented by simple programming by those skilled in the art, which is common knowledge. This application mainly protects mechanical devices, so the control method and circuit connection will not be explained in detail.

[0055] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any person skilled in the art can make some modifications or alterations to the disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model, without departing from the scope of the present utility model, shall still fall within the scope of the present utility model.
