Description

 Light bar structure

 The present invention relates to a light bar structure, and more particularly, to a light bar structure having a matrix arrangement circuit and a flexible use effect that can be flexibly bent.

Background technique

 Generally, the display devices made of LEDs are all made in a flat shape. Although this display device has a considerable degree of display function, it is not suitable for bending use because it is a flat device. For example, a flat-type LED display device is not suitable for being flexibly arranged at a corner of an eave, or a corner of an outer edge of an advertising signboard, or a corner of a car body.

 However, in daily life, there are indeed many corner positions that need to be warned or marked with light-emitting elements. Therefore, providing a flexible light-emitting display device is in line with practical needs, and a strip-shaped strip light structure is the best. Device. But because the light-emitting elements on the strip are arranged in a single row, the light-emitting elements in the strip structure can be connected in series, but this series circuit structure can make each light-emitting element normal unless it needs a larger voltage. In addition, if any light-emitting element is damaged, it will cause the entire string of lights to fail, so this is not the optimal configuration.

 In the present invention, a plurality of segmented strip-shaped conductors are arranged on a flexible insulating strip, and then a plurality of light-emitting elements (such as LEDs) are arranged on the conductor to form a matrix circuit.

 The above-mentioned arrangement of the conductor includes two ways. One is to arrange a plurality of staggered corresponding conductors on both sides of one surface of the insulator to form two rows on the same side and the conductors are staggered; or The two opposite surfaces of the insulator are arranged in a row with a plurality of conductors, the adjacent conductors in the same row have a space between them, and the conductors on the opposite sides form an offset arrangement with each other.
