Open slot type LED (Light-emitting Diode) flexible neon lamp

Abstract

The invention discloses an open slot type LED (Light-emitting Diode) flexible neon lamp comprising a banded flexible circuit board, LEDs arranged on the banded flexible circuit board and a covering layer arranged on the periphery of the banded flexible circuit board and the LEDs, wherein the banded flexible circuit board comprises a conducting region and a non-conducting region; the non-conducting region of the banded flexible circuit board is provided with an open slot and the open slot penetrates through the banded flexible circuit board; the open slot is arranged on the non-conducting region of the banded flexible circuit board and the banded flexible circuit board is separated from the adjacent conducting regions along the length direction, so that the stressing of each conducting region between the two adjacent LEDs is not influenced when the conducting region is bent and the stressing degree is greatly reduced when the conducting region is bent; on the other hand, the banded flexible circuit board between the two adjacent LEDs is placed in an arc shape and the circuit board has enough length to be stretched and bent when the circuit board is bent, so that the banded flexible circuit board can be prevented from breaking off a copper skin in a larger bending angle; and therefore, the quality of the finished LED neon lamp is guaranteed.

Description

technical field [0001] The invention relates to a decorative lighting device, in particular to a slotted LED flexible neon lamp. Background technique [0002] With the acceleration of the urbanization process, the decorative lighting of urban night scenes has also received great attention. Traditional neon lights have been widely favored by people due to the advantages of uniform and continuous light, high brightness, and bright colors. Damage, difficult transportation and installation, and high maintenance costs have been gradually restricted in big cities where electricity is in short supply; on the other hand, due to the advantages of energy saving, environmental protection, long life, and various colors, LEDs have been used in recent years. The neon light of luminous light source has also been developed rapidly, basically achieving the effect of uniform and continuous luminescence, high brightness, etc., and can be shaped arbitrarily, and can be conveniently cut and ext...

Problems solved by technology

[0003] The structure of LED neon lights currently on the market is generally to connect multiple LEDs in series and parallel, and cover the outside of the light string with a flexible plastic layer for waterproof and astigmatism. The LEDs are usually connected by electronic connecting wires and strip-shaped flexible circuit boards. These two methods have their own advantages and disadvantages: 1. The use of electronic connecting wires can ensure the quality, so that the finished LED neon lights will not break when they are bent and shaped, but it uses manual welding. Soldering the LEDs to the electronic wires is low in production efficiency. Of course, there are related machines and equipment that can realize the soldering of the electronic connecting wires to the LEDs. However, due to the immature technology, the LED light strings welded by the machine often have false soldering and false welding. Welding phenomenon seriously affects the quality of the product; 2. The strip-shaped flexible circuit board is used as the LED connection carrier. SMT technology can realize large-scale automated production, improve production efficiency, and reduce labor costs. However, because LEDD neon lights are slender, there will be multiple bends during production, packaging, transportation and installation, especially when installed on concave and convex. When the surface of the object is not flat, such as the surface of a sphere, the lamp body is bent up, down, left, and right at the same time, causing the conductive copper on the strip-shaped flexible circuit board to break, causing one or more sections of the LED neon light to be off, and the product quality cannot be guaranteed.
