Problems solved by technology

The size of the PCB board is directly related to the number of electronic components and electronic circuits installed on the PCB, as well as the number of LED light-emitting diodes installed. When the area of ​​the PCB board is too large, it will appear very bulky, affecting the application of LED lighting. and installation inconvenience
In addition, the single-layer PCB board has very large restrictions on the installation and arrangement of LEDs and other electronic components and electronic circuits. The installation and arrangement are very simple and not flexible enough.

Embodiment Construction

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] The PCB composite board of the present invention is at least a 2-layer PCB board, and the preferred PCB composite board is a 3-10-layer PCB board. In the 3 to 10-layer PCB composite boards, each layer of the PCB board includes an insulating substrate and a conductive pattern layer printed on the insulating substrate. A single-sided PCB board is printed with a conductive pattern layer on one surface of the insulating substrate, and a double-sided PCB board is printed with a conductive pattern layer on both surfaces of the insulating substrate. It can be composed of single-sided PCB boards, or only double-sided PCB boards, or a combination of single-sided PCB boards and double-sided PCB boards. The specific composition is determined according to specific needs. An insulating adhesive sheet is arranged between two adjacent PCB blocks, and ...

Abstract

The invention discloses a LED unit which comprises LEDs and a PCB composite board mounted on the LED; the PCB composite board is the PCB board provided with at least two layers; parts of the PCB boards in the layers are superposed mutually; the LEDs are arranged and distributed on the PCB board on each layer. The LED unit has the advantages that large quantity of electronic components and electronic circuits can be distributed and arranged in a smaller space; the LED mounting and distribution become flexible while the mounting and distribution mode is diverse.

Description

technical field [0001] The present invention relates to an LED lighting device, in particular, to an LED unit constituting the LED lighting device. Background technique [0002] In the LED industry, the PCB board, as the carrier of the light source, directly affects the life and failure rate of the LED. In LED lighting products, in order to ensure the good performance and quality of the product, increase the service life of the product and reduce the failure rate, a large number of electronic components are generally set in the circuit on the PCB board, such as: the installation of resistors acts as a current limiter, which can Prevent the LED from burning out due to excessive current. In the prior art, the PCB boards used in the LED industry are all single-layer PCB boards or double-layer PCB boards, that is, a conductive pattern layer is printed on one surface (single-layer) or two surfaces (double-layer) of an insulating substrate. , and then install LED light-emitting ...
