Embodiment 1

[0062] Aiming at the problems that the existing LED light bar has a relatively thick thickness, high cost, and the shear marks are prone to positional deviation and fall off, this embodiment provides a method that can greatly reduce the thickness and cost of the LED light bar, as well as a cutting A more accurate and reliable LED light bar manufacturing method is provided. The flexible circuit board of the obtained LED light bar is directly provided with a marking hole or a marking notch to mark the cutting position, and the cutting mark is printed on the surface of the light strip packaging adhesive layer, There will be no falling off, and the reliability is better; and because the marking holes are directly set between the adjacent circuit cutting units on the flexible circuit board, the setting position is more accurate and reliable, so as to avoid the cut LED light bar from not working normally; At the same time, the LED light bar can directly set the first LED chip on the ...

example 1

[0083] Example 1: The marking unit includes a first marking unit 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 As shown in the flexible circuit board 1, the flexible circuit board includes at least two adjacent circuit cutting units 11, and the circuit cutting units 11 may include at least one first circuit light-emitting unit (such as 2A to 2C shown, but not limited to 2A to 2C ), each first line light-emitting unit includes at least two pairs of electrode connection points 14 respectively used for electrical connection with the positive electrode and the negative electrode of the LED chip, and the electrical connection relationship between each pair of electrode connection points 14 is shown in the above example. , and will not be repeated here. Between adjacent circuit cutting units 11, a marking notch 12 is provided on the first side in the width direction of the flexible...

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 are 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 circuit cutting units 11, and opposite marking notches 12 are respectively provided on the first side and the second side in the width direction of the flexible circuit board. , Figure 5A and Figure 5B The marked notch shown is an arc-shaped notch, and the marks 12 at both ends are the notch after cutting in half, and other figures are similar, and will not be repeated here. Of course, it should be understood that the gap in this example can also be a gap of any other shape, such as a triangle, a polygon, etc., and the size of the gap can be flexibly set...

Abstract

The invention discloses an LED light bar and a manufacturing method thereof. Aiming at the problems that the existing LED light bar has a thick thickness, high cost, positional deviation and easy falling off of shear marks, the manufacturing method of the LED light bar provided by the present invention makes The flexible circuit board of the obtained LED light strip is directly provided with marked holes or marked gaps to mark the cutting position. Compared with printing cutting marks on the surface of the light strip packaging adhesive layer, there will be no falling off, and the reliability is better; Mark holes are set between adjacent circuit cutting units on the flexible circuit board, and the setting position is more accurate and reliable, so as to avoid the cut LED light bar from not working normally; at the same time, the LED light bar can directly set the first LED chip Encapsulation on a flexible circuit board can omit the production process of LED brackets and LED lamp beads compared to the current LED light strips. The production efficiency is higher and the cost is lower. The obtained LED light strips are COB light strips, which are thinner and can be Better meet the needs of various application scenarios.

Description

technical field [0001] The invention relates to the field of COB (Chip On Board Light, high-power integrated surface light source) light bars, 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 also placed on the thickness of LED light bars. The current LED light bar is generally composed of a flexible circuit board, LED lamp beads disposed on the flexible circuit board, and an encapsulant covering the LED lamp beads on the flexible circuit board. 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 manufacturing efficiency. [0003] In the process of using the LED light bar, the length of the light bar required for different application scenarios may be different, and the length of the produced ...
