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 board, and adopt solder hole type installation, the installation is relatively stable, because each control module, drive module and each LED are often provided by different manufacturers, therefore, once a problem occurs, the disassembly and maintenance of each control module If the control modules are directly surface-mounted and welded to make them easy to disassemble and maintain, the installation of each control module will be unstable, and it will easily fall off during use, resulting in unstable control

Abstract

The invention discloses a pin-type welded PCB (printed circuit board) and an LED (light-emitting diode) display device. The PCB (printed circuit board) comprises a PCB mainboard, at least one PCB control board, and at least one control module; each control module is fixedly arranged on the first side surface of the PCB control board; the PCB control board is provided with a plurality of copper column welding holes; each control module penetrates the copper column welding holes through pins of the control module, and is welded on the copper column welding holes; the second side surface of the PCB control board is also provided with a plurality of pin-type weld legs; each pin-type weld leg comprises a connecting part and a welding part; the connecting part is fixedly connected with the PCB control board; the PCB control board is welded and fixed with the PCB mainboard through each welding part; an included angle a is formed between the connecting part and the welding part, wherein a is more than 0 and is equal to or less than 180 degrees; the LED display device comprises an LED lamp board, a drive board, and the PCB. The control modules in the pin-type welded PCB are stable to mount, and are convenient to weld, mount and dismount.

Description

technical field [0001] The invention relates to an illuminating device, in particular to a pin-welded PCB board and an LED display device using the PCB board. 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 adopt solder hole type installation, the installation is relatively stable, because each control module, drive module and each LED are often provided by different manufacturers, ther...
