delete delete delete The method according to claim 1,
The LED is an attachment-based illuminated sign assembly, characterized in that it is arranged in a plurality of rows and columns on the silver foil reflective sheet.
The method according to claim 1,
The third unit is
a sealing groove formed on the inner surface along the formation direction of the lock member so as to simultaneously cover the edge of the surface of the high-brightness reflective film and the edge of the back of the sign
a bent extension groove that protrudes from the outer surface of the lock member and communicates with the sealing groove and allows air circulation between the high-brightness reflective film and the sign;
Attachment-based illuminated sign, formed on the locking member so that both ends of the locking member meet at a point on the edge of the high-brightness reflective film and the sign, further comprising a locking member for fixing both ends of the locking member assembly.
