Description

Technical Field

[0001] The utility model belongs to the technical field of light strips, in particular to a multi-zoned COB light strip. Background Art

[0002] Light strips, also called light bars, are a type of LED lighting product. They are characterized by cold light sources, low heat generation, high efficiency and energy saving.

[0003] COB light strip is an LED light strip manufactured using COB technology. COB technology integrates multiple LED chips on a substrate and connects the lamp beads through connecting lines to achieve high brightness, high uniformity and high energy efficiency. This makes COB light strips have higher brightness and better color reproduction, and more energy-efficient than traditional LED light strips;

[0004] like Figure 7 and Figure 8 As shown in the figure, it is the existing COB light strip structure. The general COB light strip is as follows Figure 7 As shown, the light emitted by the light source chip 2 diffuses in all directions, passes through the adhesive layer 31 mixed with fluorescent powder, and displays different colors.

[0005] The structure for controlling the light strip to emit light in two directions is as follows Figure 8 As shown, two flexible circuit boards in different directions are arranged to emit light in two directions.

[0006] After research, it was found that the above solution has certain drawbacks when used;

[0007] When the above solution is used, the main light emitted by the light strip is always directly opposite to the light source chip 2. However, in some special scenarios, the light direction of the light strip is limited, and for the convenience of installation, the light does not need to be directly opposite to the light source chip 2. In this case, the existing COB light strip will not meet the requirements.

[0008] In addition, if Figure 8 The light strip structure shown in the figure has two sets of flexible circuit boards that are vertical, which is inconvenient to install and is easily damaged during the rolling and folding process. At the same time, the use of two sets of flexible circuit boards leads to a relatively high cost and does not meet people's usage requirements.

[0009] In summary, the existing multi-partitioned COB light strips have certain drawbacks when used and do not meet people's usage requirements. Therefore, we propose a multi-partitioned COB light strip. Utility Model Content
