Abstract
An LED lamp (100) includes a lamp enclosure (10) and two LED modules (30). The lamp enclosure has a concave housing (11). The housing includes an elongated bottom plate (111) and two lateral plates (115) extending upwardly from two opposite lengthwise sides of the bottom plate respectively. An opening (156) is defined at a top side of the lamp enclosure. The LED modules each are mounted at a joint between the bottom plate and a corresponding of the lateral plates in such a manner that at least a portion of lights emitted by the LED modules is firstly directed to and reflected by an internal surface of the bottom plate, and then directed to an outside through the opening.
