  • Publication number: 20090180287
    Abstract: The present invention provides an improved lampshade for a light-emitting diode (LED) lamp, which is assembled onto the port of a hold tank on the main body of the LED lamp. The light-reflection modules, located between a port of a hold tank and LED modules in the hold tank, are positioned securely. The lampshade include a circumferential locating edge and a limitation surface. The circumferential locating edge is adapted to the wall edge of hold tank to define an inner edge and an external edge. The limitation surface is recessed into an inner edge of the circumferential locating edge and is provided with through-holes for sleeving and limitation of the light-reflection modules. A snapping portion is placed at the coupling portion of the circumferential locating edge and wall edge of the hold tank for positioning the lampshade.
