    Abstract: An LED module and a manufacturing method thereof are disclosed. The LED module includes a PCB and an LED chip connected with the PCB and a light congregating cup mounted on the PCB. Two ends of the light congregating cup define two hatches, the two hatches run-through each other and form a chip containing space within the light congregating cup. The LED chip is contained in the chip containing space and packaged therein by a packaging colloid. Because the light congregating cup is assembled with the PCB, the operating time of the production machine can be lowered. The defect rate, caused by traditional methods of setting the LED chip in a slantwise concave, can also be reduced. Moreover, the invention also provides a manufacturing method for the LED module.
