Abstract
A sealing process of LED modules includes a waterproof wire put through a wire-through hole of a heat sink to be connected with a positive-negative solder joints on a PCB board, which are subjected to glue sealing treatment. A waterproof sealing process is operated between the waterproof wire and wire-through hole. The PCB board is fixed on the heat sink. One sealing ring is placed into a groove. A ring of liquid silica gel is evenly applied along the other groove. The heat sink installed with the PCB board and the waterproof wire are inversely buckled on the lens set which is fixed with the solid silica gel ring and liquid silica gel. At least two waterproof sealing rings are used to isolate an LED chip from the outside so as to prevent all water vapor or other harmful gases from corroding the chip and the PCB.
