Description

Technical Field

[0001] This utility model relates to the field of flexible LED light strip technology, and in particular to a flexible LED light strip with DC24V power input. Background Technology

[0002] Because LEDs can only conduct electricity in one direction and have non-linear voltage-current characteristics, they cannot be directly powered by 220V AC mains power. A power supply is needed to convert the mains power into a stable DC current.

[0003] A search revealed that Chinese utility model patent CN202321498908.0 discloses a novel LED light strip, comprising a flexible circuit board and a flexible adhesive layer wrapping the flexible circuit board. The flexible circuit board includes several circuit board units, with shear lines between adjacent circuit board units and connecting conductors at the shear lines to electrically connect the circuit board units. Each circuit board unit has multiple LED beads and multiple resistors, with the LED beads and current-limiting resistors connected in series. The light strip is composed of multiple circuit board units connected in parallel, and each circuit board unit operates at 36V. It eliminates the need for capacitors and high-power resistors, and each circuit board unit has relatively low power consumption, allowing the light strip to extend further and accommodate more LED beads, significantly exceeding the capabilities of existing low-voltage light strips, resulting in superior energy efficiency and greater practicality.

[0004] For example, Chinese utility model patent application CN201920821530.0 discloses a resistor-free low-voltage LED light strip, including a flexible circuit board. Positive and negative power lines extending along the length of the circuit board are arranged on both sides of the flexible circuit board. Multiple LEDs are soldered between the positive and negative power lines, and the flexible circuit board and the LEDs are covered by a sheath. The multiple LEDs are connected in series with a constant current chip to form an LED series unit. Multiple LED series units are connected in parallel to the positive and negative power lines. The operating voltage of the LED series unit is 24V. This utility model uses a low-power constant current chip to suppress surges, eliminating the need for high-power resistors. Each LED series unit has relatively low power, allowing the same power supply to drive more LED series units, thus extending the light strip to a longer length. Using this utility model, the light strip can be extended to 20 meters, far exceeding existing low-voltage light strips.

[0005] While the existing flexible LED light strips can meet basic usage needs, their structure is relatively complex, the wiring is not reasonable, they are inconvenient to cut during use, and the user experience is poor. Utility Model Content
