Technical Field

The utility model relates to LED circuit board subassembly technical field, concretely relates to novel circuit board subassembly suitable for multiple LED.

Background

The LED circuit board is a PCB circuit board for mounting an LED lamp, and usually an aluminum substrate is used as a substrate thereof, and a light emitting diode and other electronic components are soldered on the substrate. After an LED circuit board is produced, the positions and sizes of holes for inserting light emitting diodes and other electronic components are basically fixed. On one LED circuit board, for other electronic components, the possibility of changing the model specification is not great, so the position of the hole is fixed and has no obstacle; however, for the LEDs on one LED circuit board, since different users have different preferences and different requirements for the light emitting color and the light emitting power of the LEDs, the LEDs with different colors and powers can be selected. Because the specifications of the light-emitting diodes with different colors and powers are not always the same, namely, some pins are thick, some pins are thin, the distance between some two pins is larger, and the distance between some two pins is smaller, the position for installing the LED lamp beads on one LED circuit board is probably not suitable for installing the LEDs with different specifications (although the LED can be forcibly inserted in a pin bending mode, the pins can be damaged by the bending pins to further influence the service life of the LED, and meanwhile, the pins are also influenced to be attractive), so that the use of the LED circuit board is limited to a certain extent.
