Circuit board structure with modulized luminous diode

The utility model relates to a circuit board structure provided with modularization luminous diode, single or plural luminous diode modules are arranged correspondingly inside the single or plural through holes of the circuit board, and is directly contacted with the rear metal cooling plate so as to cool the heat generated by the luminous diode module directly through the metal cooling plate, thereby improving the cooling efficiency of the integrated structure. In addition, the luminous diode of the utility model adopts module group design, so that only by briefly changing different wiring circuit board and correspondingly placing the luminous diodes to the through hole of the same quantity, various of luminous diode circuit board structures can be matched and combined. The utility model provides a modularization design which is extremely convenient in design and assembly, and can effectively simplify the manufacture procedure and reduce the cost.
