Abstract:
1. An LED lamp comprising: a housing made of a heat conductive material, the housing comprising an elongate base plate and first and second sidewalls extending downwardly from two opposite edges of the base plate, respectively, a light emitting window being defined between free ends of the first and the second sidewalls and located under the base plate, the base plate having a heat absorbing surface facing the light emitting window and a heat dissipating surface opposite to the heat absorbing surface; an LED module received in the housing and comprising a printed circuit board mounted on the heat absorbing surface of the base plate and a plurality of LED components mounted on the printed circuit board, the LED components facing the light emitting window; a fixing bracket mounted on the housing and facing the heat dissipating surface of the base plate, the fixing bracket having a longitudinal length shorter than that of the base plate of the housing, the fixing bracket and the base plate of the housing cooperatively defining a receiving space with two openings at two opposite longitudinal ends of the receiving space; a power driver source being provided for supplying electrical power for the LED components, the power driver source being mounted to the fixing bracket and received in the receiving space; and an optical lens being disposed at the light emitting window; wherein a plurality of fins are formed on the heat dissipating surface of the base plate, an airflow channel being defined between every two adjacent fins; wherein the first sidewall has a C-shape, and the second sidewall has an inverted C-shape, an open side of the first sidewall facing an open side of the second sidewall; wherein the free end of the first sidewall and the free end of the second sidewall each define a first latching groove, and two lateral edges of the optical lens are received in the two first latching grooves, respectively; and wherein two opposite lateral sides of the fixing bracket each form a securing portion, the housing further comprising two connecting plates corresponding to the two securing portions, each of the two connecting plates extending inwardly and upwardly from one of the two opposite edges of the base plate, each of the two connecting plates and the base plate of the housing cooperatively defining a second latching groove, each of the two securing portions being engaged in a corresponding second latching groove.
