Abstract
An LED lamp (100) includes a lamp enclosure (10), a heat sink (51) and two LED modules (30). The lamp enclosure has a recess (15) and an opening (156). The heat sink is received in the recess of the lamp enclosure. The LED modules are attached to a bottom of the heat sink and oriented downwardly and outwardly towards an internal surface (1110) of the lamp enclosure. Light emitted by the LED module is firstly directed to the internal surface and other internal surfaces (130, 1130), and then reflected from the internal surfaces to an outside of the LED lamp through the opening.
