Beschreibung
Zusammenfassung:	The invention relates to a strip-type LED (Light-Emitting Diode) lamp with symmetric light distribution, wherein a substrate is arranged in a lamp housing and is provided with a plurality of LED light sources, the plurality of LED light sources are arranged in a length direction of a lamp body and directly face transparent members, the transparent members are symmetric to a midplane, and the midplane is a plane which is passed through the LED light sources and is vertical to the substrate; the inner surfaces and/or the outer surfaces of the transparent members are free curved surfaces which are stretched in a length direction of the lamp body, and the light rays generated by the LED light source are symmetrically distributed to be symmetric to the midplane after the light rays are reflected through the transparent members. The strip-type LED lamp provided by the invention is simple in structure, the symmetric light distribution is carried out on the LED light sources through lens members, additional optical e
