Patent ID: 8220976

Claim:
An LED (light emitting diode) lamp comprising: a heat sink; an LED module mounted on a top side of the heat sink; a driving circuit module mounted on a bottom side of the heat sink; a top cover slidably engaging with the heat sink and covering the LED module; and a bottom cover slidably engaging with the heat sink and covering the driving circuit module; wherein the heat sink comprises two spaced heat dissipating plates and a heat absorbing plate sandwiched between the two heat dissipating plates and connecting with central portions of the heat dissipating plates, respectively, the LED module is mounted on a top surface of the heat absorbing plate, and the driving circuit board module is mounted on a bottom surface of the heat absorbing plate; and wherein two extending portions extend from top and bottom ends of each of the heat dissipating plates to define two guiding grooves between the extending portions and the heat absorbing plate, opposite lateral sides of the top cover and opposite lateral sides of the bottom cover are slidably received in corresponding guiding grooves.
