Problems solved by technology

[0003] In the prior art, the control modules used to control the LEDs in the LED module are generally installed on the same PCB board as the driving modules, or are installed on the same PCB as the driving modules and the LEDs in the way of integrating the lamps and drivers. On the PCB, and in order to make the installation of each control module more stable and not easy to be damaged, each control module is installed with solder holes, and the installation is relatively stable. Since each control module, drive module and each LED are often produced by different manufacturers Provided by the manufacturer. Therefore, once a problem occurs, it is difficult to disassemble the control modules installed in the welding hole type. Therefore, maintenance and replacement of each control module becomes a difficult problem. If the control modules are directly surface-mounted, the maintenance of each control module It is relatively easy to replace and replace, but the installation of the surface-mounted control modules is relatively unstable, and it is easy to partially or completely fall off during use, resulting in unstable control

Abstract

The invention discloses a copper pillar type welded printed circuit board (PCB) and a light-emitting diode (LED) display device. The PCB comprises a PCB mainboard, at least one PCB control panel and at least one control module; the PCB control panel is provided with a plurality of integral copper pillar welding holes; the pins of the PCB control panel are welded on the PCB control panel through the integral copper pillar welding holes; and each side of the PCB control panel is provided with a plurality of partial copper pillar welding holes which are connected with the preset circuits of the PCB mainboard, and are used for welding, fixing and conducting the PCB control panel. The LED display device comprises an LED light panel and the PCB. In the invention, each control module is installed firmly, has less possibility of being damaged and is quite simple and convenient to maintain and replace, flexible in use and lower in manufacturing cost.

Description

technical field [0001] The invention relates to an illuminating device, in particular to a PCB board welded with copper pillars and an LED display device. Background technique [0002] At the present stage, under the circumstances of global pursuit of health, environmental protection pressure, and energy crisis, semiconductor lighting has been recognized by the world as an important way of health, energy saving and environmental protection, and its application scope is expanding at a faster speed. [0003] In the prior art, the control modules used to control the LEDs in the LED module are generally installed on the same PCB board as the driving modules, or are installed on the same PCB as the driving modules and the LEDs in the way of integrating the lamps and drivers. On the PCB board, and in order to make the installation of each control module more stable and not easy to be damaged, each control module is installed with solder holes, and the installation is relatively st...
