Description

Technical Field

[0001] The utility model belongs to the technical field of LED light strips and relates to an ultra-low temperature resistant cable used for LED light strips. Background Art

[0002] LED light strips refer to LEDs assembled on a strip-shaped FPC or PCB hard board. They are named because their product shape resembles a strip. LED light strips are generally divided into two types: flexible LED light strips and LED hard light strips. Flexible LED light strips use FPC as the assembly circuit board and SMD LEDs for assembly, making the product only 0.1CM thick and taking up no space. LED hard light strips, on the other hand, use PCB hard boards as the assembly circuit board. LEDs are assembled with SMD LEDs or with plug-in LEDs. Different components are used depending on the needs. The low temperature of the components during use will have a greater impact on their working efficiency, so the impact of low temperature on LED light strip cables cannot be ignored. Due to the lack of effective low-temperature protection measures, the following problems may occur:

[0003] First, as the temperature drops, the insulation material of the cable may become brittle and prone to cracking or damage, causing safety accidents such as short circuits or electric shocks. Second, in a low temperature environment, the resistance and capacitance of the cable will also change, which may cause current instability and affect the normal lighting of the LED light strip.

[0004] In addition, due to the thermal expansion and contraction effect, the cable may expand and contract when the temperature changes, which may cause the connection part to loosen or fall off, affecting the normal use of the light strip. Finally, low temperature will also accelerate the aging process of the cable material, resulting in a shortened service life of the cable. Therefore, there is an urgent need for an ultra-low temperature resistant cable for LED light strips to solve the above problems. Utility Model Content
