The invention discloses a structure for preventing LED conductive adhesive from loosening during soldering or use and relates to the field of LED manufacturing. The structure is characterized by comprising a bracket bowl cup, a cup bottom wire, the conductive adhesive, an LED wafer, a wire and packaging adhesive. At present, for preventing a substrate in a silver layer from affecting use of an LEDdue to oxidation, many manufacturers increase the anti-silver oxidant on the silver layer on a surface of a solid crystal region plate through the existing electroplating technology, however, the anti-silver oxidant solidifies when the anti-silver oxidant does not completely volatilize before the LED is produced, which causes chemical substances in the conductive adhesive to react with the anti-silver oxidant, in the subsequent high-temperature process or daily use, a problem that the LED wafer can not continue to work due to the conductive adhesive loosening away from the solid crystal region plate occurs. For solving the problem, a medium capable of connecting the conductive adhesive and the solid crystal region plate and realizing conduction is added between the conductive adhesive andthe solid crystal region plate, even if the LED wafer is disengaged from the solid crystal region plate due to the lack of adhesion of the conductive adhesive, such a problem of an open dead lamp does not occur.
