Abstract: An improved lampshade of an LED lamp, assembled onto the port of hold tank on the main body of LED lamp so that light-reflection modules located between port of hold tank and LED modules in the hold tank are positioned securely. The lampshade has a circumferential locating surface and a limitation surface. The circumferential locating surface is adapted with the wall edge of hold tank to define an inner edge and an external edge. The limitation surface is recessed into the circumferential locating. A snapping portion is placed at the coupling portion of the circumferential locating surface and wall edge of the hold tank for positioning of the lampshade.

Abstract: The light-emitting diode (LED) lamp of the present invention has a main body with an inner space provided with an open end and inner wall. The LED baseplate is mounted into the inner space. The inner wall is provided with a reducing through-hole, and front and rear stop edges are formed on the wall. The back side of the LED baseplate is sustained by the front stop edge. An insertion portion for plugging into the reducing through-hole is provided with one end of the cooling seat. The end surface of the cooling seat is sustained by the back side of the LED baseplate, and a retaining edge is arranged around the other end of the cooling seat for positioning at the rear stop edge. The LED baseplate and cooling seat are positioned through a locator.
