Embodiment 1

[0062] Aiming at the problems of thicker thickness and high cost in the existing LED light bar, and the position deviation and easy falling off of the shear marks, this embodiment provides a cutting method that can greatly reduce the thickness and cost of the LED light bar, and set Marking is a more accurate and reliable method for making LED light strips. The flexible circuit board of the produced LED light strips is directly provided with marking holes or marking gaps to mark the cutting position. Compared with printing the cutting marks on the surface of the light strip packaging adhesive layer, There will be no falling off, and the reliability is higher; and because the marking hole is directly set between the adjacent circuit cutting units on the flexible circuit board, the setting position is more accurate and reliable, and the LED light bar after cutting can not work normally; At the same time, the LED light bar can directly arrange the first LED chip on the flexible cir...

example 1

[0083] Example 1: the marking unit includes a first marking unit located on the first side, wherein the first marking unit may be a marking hole or a marking notch.

[0084] For example, see Figure 3A and Figure 3B The shown flexible circuit board 1 includes at least two adjacent line cutting units 11 on the flexible circuit board, and the line cutting unit 11 may include at least one first line light emitting unit (such as Figure 2A to Figure 2C shown, but not limited to Figure 2A to Figure 2C ), each of the first line light-emitting units includes at least two pairs of electrode connection points 14 for electrical connection with the positive and negative electrodes of the LED chip, and the electrical connection relationship between each pair of electrode connection points 14 is shown in the above example , which will not be repeated here. Between adjacent line cutting units 11, a marking notch 12 is provided on the first side in the width direction of the flexible ci...

example 2

[0086] Example 2: The marking unit includes a fourth marking unit and a fifth marking unit which are located on the first side and the second side respectively and opposite to each other. The first marking unit in this example may be a marking hole or a marking notch.

[0087] For example, see Figure 5A and Figure 5B As shown in the flexible circuit board 1, the flexible circuit board includes at least two adjacent line cutting units 11, and the first side and the second side of the width direction of the flexible circuit board are respectively provided with opposite marking gaps 12 , Figure 5A and Figure 5B The marked notch shown is an arc-shaped notch, and the marks 12 at both ends are the notch cut in half. Other figures are similar and will not be repeated here. Of course, it should be understood that the notch in this example can also be a notch of any other shape, such as triangle, polygon, etc., and the size of the notch can be flexibly set according to specific...

Abstract

The invention discloses an LED light bar and a manufacturing method thereof. The objective of the invention is to solve problems that an existing LED light bar is thick, cost is high, and the shear marks are prone to position deviation and falling off; according to the LED light bar manufactured through the LED light bar manufacturing method, mark holes or mark notches are directly formed in the flexible circuit board to mark the shearing position, and compared with the mode that shearing marks are printed on the surface of a light bar packaging adhesive layer, the situation of falling cannotoccur, and reliability is higher; the marking holes are directly formed between the adjacent line shearing units on the flexible circuit board, so that the arrangement position is more accurate and reliable, and the situation that the sheared LED light bar cannot work normally is avoided; meanwhile, according to the LED light bar, the first LED chip can be directly arranged on the flexible circuitboard to be packaged; compared with an existing LED light bar, the manufacturing process of an LED support and LED light beads can be omitted, the manufacturing efficiency is higher, the cost is lower, the obtained LED light bar is a COB light bar, the thickness is smaller, and the requirements of various application scenes can be better met.

Description

technical field [0001] The present invention relates to the field of COB (Chip On Board Light, high-power integrated surface light source) light bar, in particular to an LED light bar and a manufacturing method thereof. Background technique [0002] With the increasing application of LED light bars, higher and higher requirements are put forward for the thickness of LED light bars. The current LED light bar generally consists of a flexible circuit board, LED lamp beads arranged on the flexible circuit board, and packaging glue covering the LED lamp beads on the flexible circuit board. Wherein, the LED lamp bead is composed of an LED bracket, an LED chip placed in the LED bracket, and an encapsulant that encapsulates the LED in the bracket, resulting in a thicker light bar, high cost and low production efficiency. [0003] During the use of the LED light bar, the length of the light bar required by different application scenarios may be different, but the length of the manuf...
