Description

An LED light fixture that can be bent and twisted at will. Technical Field

[0001] This invention relates to the field of LED lighting technology, and more particularly to an LED lighting fixture that can be bent and twisted arbitrarily. Background Technology

[0002] Currently, LED lights, in terms of appearance, are long, strip-shaped lights with a waterproof shell and uniform light output. Because their waterproof shells are made of soft materials such as silicone, PVC, and TPU / TPE, these lights are generally called "silicone light strips," "neon light strips," or "flexible light strips" in the LED industry. They are generally used for architectural outlining, urban lighting, and landscape lighting, requiring linear lighting to achieve lighting outlining and beautification effects. They belong to a category of linear lighting products in the industry. Currently, the linear application of these products in the market mainly manifests as straight line applications, side-curved plane curve applications, and top-curved plane curve applications, and there are also some products for spatial curve applications.

[0003] However, in the existing technology, the installation reliability of products using spatial curves is not good. During the installation process, functional failures such as partial product failure to light up are easily caused. With changes in ambient temperature, the product will expand and contract with temperature, which will lead to PCB breakage and product functional failure. The product characteristics of single left-right or up-down bending planar curves restrict installation behavior and limit application scenarios.

[0004] Summary of the Invention

[0005] The purpose of this invention is to provide an LED lamp that can be arbitrarily bent and twisted, aiming to solve the problems of poor installation reliability of products using spatial curves in the prior art, which can easily cause functional failures such as partial product failure during installation. As the ambient temperature changes, the product will expand and contract with temperature changes, resulting in PCB breakage and product functional failure. The product characteristics of single left-right or up-down bending planar curves restrict installation behavior and limit application scenarios.

[0006] To achieve the above objectives, the present invention employs an LED lamp that can be arbitrarily bent and twisted, comprising a flexible light strip, mounting slots, a plug, a wire outlet plug, a water-blocking ring, and a power cord.
