Problems solved by technology

However, the LED lamp panels in the prior art cannot be cut according to any shape due to the limitation of the connection method and the like.
Therefore, when corresponding to the application of a specific shape, the LED light board must be specially made according to the specific shape, which makes the use of the LED light board inconvenient and correspondingly increases the manufacturing cost

Abstract

The invention provides an LED lamp panel. The LED lamp panel comprises a plurality of LED units, a first conducting layer, a second conducting layer and a substrate layer. Each LED unit comprises an LED chip, the positive electrode of each LED unit is electrically connected with one of the first conducting layer and the second conducting layer, and the negative electrode of each LED unit is electrically connected with the other one of the first conducting layer and the second conducting layer. The LED units are placed on the substrate layer. Predetermined gaps are reserved in the positions, corresponding to the LED units, of the first conducting layer and / or the second conducting layer. The LED lamp panel has the advantages that as long as it is guaranteed that the first conducting layer and the second conducting layer can conduct electricity continuously, the LED lamp panel can correspond to various specific shapes for use, and thus the LED lamp panel can be used in lamp boxes of different dimensions more flexibly.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an LED lamp board. Background technique [0002] LED lights are widely used in the field of lighting because of their power saving, long life, small size, and ability to emit light in various colors. [0003] In some background lighting applications, especially in the background lighting applications of billboards, light boxes, etc., LED light panels composed of LED arrays have begun to be widely used. However, the LED lamp panels in the prior art cannot be cut according to arbitrary shapes due to limitations such as their connection methods. Therefore, when corresponding to the application of a specific shape, it is necessary to specially manufacture the LED light board according to the specific shape, which makes the use of the LED light board inconvenient and correspondingly increases the manufacturing cost. [0004] The information disclosed in the Background of the Invent...
