Description

Technical Field

[0001] This utility model relates to the field of neon light strip technology, and in particular to a splicing silicone neon light strip with no pressure drop. Background Technology

[0002] Standard low-voltage silicone neon light strips are available in 12V and 24V versions. They are co-extruded from FPC light boards and silicone. When powered by a single end, the standard 12V light strip is 5 meters long and the 24V light strip is 10 meters long. If a 12V light strip is spliced ​​to a 10-meter length or a 24V light strip is spliced ​​to a 20-meter length, a voltage drop will occur at the beginning and end of the product, resulting in a noticeable difference in brightness between the beginning and end, which affects the performance.

[0003] This type of LED strip uses an internal FPC flexible circuit board. To allow for easy bending, the copper thickness of the internal light board generally cannot be too thick; otherwise, the product is prone to breakage or the cost is too high. When the product is too long, during power transmission from the head to the tail, energy loss will cause a voltage difference between the two ends. The longer the product, the greater this voltage difference will be, resulting in a greater difference in brightness between the two ends and thus affecting the product's performance.

[0004] Typically, solutions for this type of product use power supply at both ends. However, this makes wiring difficult in some applications, or prevents the product from being flexibly spliced ​​and plugged in for different lengths. To address these issues, a splicing, voltage-drop-free silicone neon light strip is needed. Utility Model Content

[0006] This utility model proposes a splicing, pressure-drop-free silicone neon light strip, including a silicone shell, an internal light board and a copper strip, both of which are integrally formed with the silicone shell through an extrusion molding process. The copper strip is located on the back of the light board, and both ends of the light board are provided with electrically conductive copper sheets, which are welded to the copper strip.

[0007] Preferably, the silicone shell is composed of a silicone diffusion shell and a silicone light-shielding shell spliced ​​together. The cross-section of the silicone light-shielding shell is U-shaped, and the U-shaped end of the silicone light-shielding shell wraps around one end of the silicone diffusion shell.

[0008] Preferably, both ends of the plurality of lamp panels are electrically welded to the copper via positive and negative electrodes using electrically conductive copper sheets.

[0009] Preferably, both the lamp plate and the copper strip are located inside the left end groove of the silicone diffusion shell, and the copper strip is located on the left side of the lamp plate.
