The invention relates to a lead frame material band, the combination of an insulated shell and the same and an LED module using the combination. The lead frame material band comprises two first conduction frames and at least two second conduction frame units, wherein the two first conduction frames are mutually spaced, extend along a first direction and are used for connecting an external power supply; the two second conduction frame units are arrayed between the two first conduction frames along a second direction which is different from the first direction, and a first fixed crystalline region is supplied between each first conduction frame and any one second conduction frame unit. Because a printed circuit of a circuit board is replaced by using the conduction frame, the invention solves the problem that public-known luminescent grains are difficult to position and can be difficultly processed, the conduction frames which can be provided with different numbers of luminescent grains can be changed by punching the second conduction frame units with different group numbers and different numbers of second conduction frames so as to manufacture surface light sources with different sizes.
