Description

Technical Field

[0001] This utility model relates to the field of neon light strips, and more particularly to a long cascaded LED neon light strip. Background Technology

[0002] Currently, the outdoor lighting industry is booming, and outdoor building lighting, as a key component, has gained extensive development opportunities. However, a significant shortcoming of existing LED neon light strips on the market is that their connection length is mostly limited to 10 meters. When attempting to exceed this length limit in practical applications, especially in hot weather, the light strips are prone to loosening. This loosening not only significantly reduces the luminous effect of the light strips, failing to achieve the desired lighting presentation, but also greatly increases the complexity and difficulty of construction, creating numerous obstacles to the smooth progress of outdoor building lighting projects.

[0003] To address the aforementioned issues, this application proposes a long cascaded LED neon light strip. Utility Model Content

[0004] (a) Purpose of the utility model

[0005] To address the technical problems existing in the background art, this utility model proposes a long cascaded LED neon light strip. This utility model injects liquid water into the shielding body of the light strip. On the one hand, the liquid water can act as a medium for auxiliary cooling; on the other hand, as the temperature of the light strip rises during operation, the light strip can still remain tight in the long connection state.

[0006] (II) Technical Solution

[0007] To solve the above problems, this utility model provides a long cascaded LED neon light strip, including a light-emitting body, the bottom and both sides of which are wrapped with a light-shielding body so that the remaining surface of the light-emitting body forms a light-transmitting surface;

[0008] The light-emitting element contains interconnected surface-mount LEDs, a constant current IC, and an integrated IC FPC circuit board.

[0009] The light-shielding body has internal wires, and the wires are electrically connected to the integrated IC FPC circuit board;

[0010] The light-shielding body has an internal channel filled with water.

[0011] Preferably, the light-shielding body is provided with a visible cutting window.

[0012] Preferably, both sides of the light-shielding body are provided with mounting clip grooves.

[0013] Preferably, both the light-emitting body and the light-shielding body are provided with a tail plug and a wire outlet plug at their tail ends.

[0014] Preferably, the conductor is connected to a silicone wire, and the silicone wire passes through the outlet plug.

[0015] Preferably, the silicone wire is electrically connected to a low-voltage driving power supply.

[0016] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0017] By injecting liquid water into the shield of the light strip, multiple benefits can be achieved. Firstly, the liquid water acts as an auxiliary cooling medium. When the light strip is used for a long time, especially in high-temperature environments, the water can absorb heat and help lower the temperature of the light strip, thereby reducing the performance loss of the light strip caused by high temperature. Secondly, as the temperature of the light strip rises during operation, the water temperature will also rise accordingly. Water has the property of thermal expansion and contraction. The rise in water temperature causes the liquid to expand, which in turn provides outward tension to the entire light strip. This tension can increase the overall strength of the light strip, allowing it to remain tight even under long-term connection, greatly reducing the probability of loosening and ensuring the stable use of the light strip in outdoor building lighting projects.

[0018] The surface mount LED chips, constant current ICs, and wires are integrally formed using an extrusion machine. During the integral forming process, the wires are tightly attached to the positive and negative polarities on the back of the surface mount LED chips and constant current ICs, which is equivalent to increasing the thickness of the bottom copper foil of the circuit board, thus achieving the requirement of longer cascading.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0024] like Figure 1-3 As shown, the present invention proposes a long cascaded LED neon light strip, including a light-emitting body 1 and a light-shielding body 2. The light-emitting body 1 is a vapor phase gel light-emitting body, and the light-shielding body 2 is a silicone light-shielding body. The light-emitting body 1 is the core light-emitting component, and its bottom and both sides are tightly wrapped by the light-shielding body 2. Through this unique wrapping method, the remaining surface of the light-emitting body 1 other than the wrapped surface forms a light-transmitting surface 101, ensuring that the light can be accurately emitted outward according to the design requirements to achieve the ideal lighting effect.

[0025] Inside the light-emitting element 1, there are interconnected surface-mount LEDs, a constant current IC 4, and an integrated circuit board 5. The surface-mount LEDs are responsible for generating light, and the surface-mount LEDs and constant current IC 4 can precisely control the current to ensure stable light emission. The integrated circuit board 5 plays a key role in integrating circuits and transmitting signals, making the electrical performance of the entire light-emitting element 1 stable and reliable.

[0026] The light-shielding body 2 contains a conductor 6, which is a 2.5 square millimeter copper wire. This conductor 6 is electrically connected to the integrated IC FPC circuit board 5. Its function is to provide a power transmission channel for the electrical components inside the light-emitting body 1, ensuring a stable power supply so that the light strip can emit light normally. At the same time, a channel is specially designed inside the light-shielding body 2, and liquid water is placed in the channel.

[0027] The surface-mount LED chips, constant current IC 4, and lead wire 6 are integrally formed using an extrusion machine. During this process, the lead wire 6 is tightly bonded to the back of the surface-mount LED chips and constant current IC 4, and precisely laid out according to the requirements of positive and negative polarity. This effectively increases the thickness of the bottom copper foil on top of the original circuit board. This structural optimization significantly improves the electrical transmission performance of the light strip, enabling it to meet longer cascading requirements. It effectively overcomes the bottleneck of limited connection length in traditional LED neon light strips, providing a more advantageous lighting solution for applications such as outdoor building lighting.

[0028] On the one hand, when the light strip is in operation for a long time, especially in hot outdoor environments, its temperature will gradually rise over time. At this time, the liquid water in the channel, as an effective medium for auxiliary cooling, can absorb the heat generated by the light strip due to its excellent thermal conductivity, thereby effectively reducing the overall temperature of the light strip, reducing the performance loss of various components of the light strip caused by high temperature, such as surface-mount LEDs and circuit boards, extending the service life of the light strip, and ensuring the continuous and stable operation of outdoor building lighting projects.

[0029] On the other hand, due to the thermal expansion and contraction properties of water, the water temperature increases accordingly as the light strip heats up during operation, causing the liquid water to expand. The outward tension generated by this expansion acts on the entire light strip structure, providing additional support for the light strip. This allows the light strip to remain taut even with long connections, greatly reducing the probability of loosening due to excessive connection length or high temperature, and ensuring the stability of the light strip in outdoor building lighting applications.

[0030] The light-shielding body 2 is equipped with a visible cutting window 3, which greatly facilitates the installation of light strips on site. When the light strip needs to be cut and adjusted according to the actual dimensions of the building, the construction personnel can clearly observe the internal wiring structure through the visible cutting window 3, accurately locate the cutting position, and avoid accidentally cutting the wires 6 or other critical components, thereby improving construction efficiency, reducing construction difficulty, and ensuring that the cut light strip can still work normally.

[0031] Both sides of the light-shielding body 2 are provided with mounting clip slots 7. During the actual installation of outdoor building lighting projects, construction workers can use these mounting clip slots 7 to conveniently fix the light strip to the clips or slots pre-set on the building surface without the need for additional complicated fixing tools or a large amount of adhesive materials. This not only simplifies the installation process and improves the installation speed, but also makes the installation of the light strip more secure and reliable, adapting to various complex outdoor environments.

[0032] Both the light-emitting element 1 and the light-shielding element 2 are equipped with end caps 8 and wire exit plugs 9 at their tail ends. The main function of the end caps 8 is to seal the tail end of the light strip, preventing dust, rainwater, and other external impurities from entering the interior of the light strip and causing corrosion or short circuits to the internal electrical components and wiring, thus ensuring the stability of the internal environment of the light strip and extending its service life. The wire exit plug 9 provides a dedicated channel for the lead-out of the wire 6, ensuring that the wire 6 is effectively protected when passing through the tail end of the light strip, preventing the outer sheath of the wire 6 from being scratched or damaged, which could lead to electrical safety hazards.

[0033] Conductor 6 is connected to silicone wire 10, which passes through outlet plug 9. Silicone wire 10 has good flexibility, high temperature resistance, and insulation properties, enabling it to adapt to complex and variable outdoor weather conditions and ensuring stable power transmission. Silicone wire 10 is electrically connected to low-voltage drive power supply 11, which converts mains power into low-voltage DC power suitable for the light strip's operation, providing a stable and safe power supply for the light strip and further ensuring its reliable operation in outdoor building lighting projects.

[0034] This long cascaded LED neon light strip has significant advantages in structural design, functional implementation, and installation. It can effectively solve the problems of limited connection length, easy loosening, and high construction difficulty of existing LED neon light strips, bringing innovative solutions to the outdoor building lighting industry.
