Abstract
The present disclosure provides a fire resistant LED module, including a metal mask and a printed circuit board (PCB). A layer of flame-retardant glue is coated on one side, facing the PCB, of the metal mask, and the metal mask is pasted with the PCB through the flame-retardant glue. A sub-black insulating surface layer is disposed on the metal mask. The present disclosure further provides a manufacturing method of the fire resistant LED module, including following steps: processing surfaces of the metal mask after etching to form the sub-black insulating surface layer; coating the flame-retardant glue on one surface of the metal mask facing the PCB; and covering the metal mask on the PCB through the flame-retardant glue. The sub-black insulating surface layer is formed through processing the surfaces of the metal mask
