Problems solved by technology

Due to the limitations of LED patches, the existing light strips cannot achieve 360-degree lighting around the surface and emit light throughout the body. At the same time, the flexible strip circuit board and coating of the existing light strips can only be bent at a specific angle, and cannot be bent at any angle. bend or twist

Embodiment Construction

[0034] The present invention will be further described below in conjunction with accompanying drawing.

[0035] see Figure 1 to Figure 4 , a flexible LED patch light strip, comprising:

[0036] A core wire 1 is a strip with a predetermined length extruded from flexible plastic. The core wire 1 is embedded with a wire 11. Usually, the working voltage of the wire 11 is the rectified civilian voltage. The wire 11 runs along the core wire 1. Arranged in the length direction and equal to the length of the core wire 1; at least one flexible circuit board 2, and a plurality of LED patches are arranged on the flexible circuit board ( Figure 1-4 omitted, the flexible ribbon circuit board as Figure 9 As shown, there are multiple LED patches 20 and resistors 29), the flexible strip circuit board has leads (not shown in the figure), and the leads are electrically connected to the above-mentioned leads to form the LED patches on the flexible strip circuit board Power supply; a claddi...

Abstract

The invention relates to a decorative illumination device, in particular to a flexible light-emitting diode (LED) surface mount device (SMD) lamp belt. The LED SMD lamp belt comprises a core wire, at least one flexible circuit board and a coating layer. A lead wire is buried inside the core wire and arranged along the length direction of the core wire, and the length of the lead wire is the same as that of the core wire. A plurality of LED SMDs are arranged on the flexible circuit board, the flexible circuit board is provided with a leading wire, and the leading wire is in electric connection with the lead wire to provide power for the LED SMDs arranged on the flexible circuit board. The coating layer coats outside the core wire and the flexible circuit board. The flexible circuit board comprises a belt-shaped body which is arranged along the length direction of the core wire, two long edges of the belt-shaped body are provided with several wing-shaped auxiliary boards in protruding mode, and the wing-shaped auxiliary boards are arranged at intervals and extend along the circumference direction of the core wire. All LED SMDs or some LED SMDs of the flexible circuit board are arranged on the wing-shaped auxiliary boards. The wing-shaped auxiliary boards extend along the circumference direction of the core wire, and therefore the whole circumference surface of the core wire can be provided with LEDs, illumination of 360 degrees can be achieved, and the whole body can emit light and illuminate.

Description

technical field [0001] The invention relates to a decorative lighting device, in particular to a flexible LED patch light strip. Background technique [0002] Flexible LED SMD light strip has the characteristics of high brightness, long service life, energy saving and environmental protection, etc. It is widely used in the decorative lighting market, such as in signboards, subtitle advertisements, outlines of buildings, indoor ceiling lighting, and interior decoration of automobile bodies and other lighting places. The flexible LED patch light strip currently on the market is generally composed of a core wire, a flexible strip-shaped circuit board and a coating layer, and the LED patch is arranged on the flexible strip-shaped circuit board. Due to the limitations of LED patches, the existing light strips cannot achieve 360-degree lighting around the surface and emit light throughout the body. At the same time, the flexible strip circuit board and coating of the existing lig...
