Special SMD emitting diode

The utility model relates to a light -emitting diode technology field, and disclose a special SMD emitting diode, which comprises a substrate, the front of base plate is passed through the connectingpiece and is articulated with the connecting block, the bottom fixedly connected with safety cover of connecting block, the joint groove has been seted up in the front of base plate, the bottom fixedly connected with joint board of safety cover, the joint board is located the inside in joint groove. This special SMD emitting diode, accomodate the piece through the setting, the movable rod, springand push pedal, promote the push pedal, relieve movable rod and buffer fixing the joint board, thereby accomplish the change to the chip, utilize the spring from the dynamic resilience, make the movable rod kick -back automatically, restrict the joint board between movable rod and buffer, thereby accomplish fixing the safety cover, the encapsulation of adoption plastic lens has been avoided, thereby the mesh of the change
