Abstract:
The present invention relates to a light emitting module, a lens, and a tubular lighting apparatus comprising the same. A light emitting module according to an embodiment of the present invention may comprise: a plurality of light emitting elements disposed on a substrate; and a plurality of lenses disposed above the plurality of light emitting elements, respectively, so as to diffuse light emitted from the light emitting elements, wherein: each of the plurality of lenses includes a light entrance part to which light emitted from each of the light emitting elements is incident and a light exit part from which the incident light is output; when viewed in the plane view thereof, each of the light entrance part and the light exit part has a major axis and a minor axis; and the major axis of the light entrance part and the major axis of the light exit part are arranged to form a predetermined angle with each other. According to the present invention, light emitted from a light emitting element can be diffused in a narrow and long direction through a lens, and thus a shadow or a hotspot does not occur even when a reduced number of light emitting elements are used in a lighting apparatus such as a tubular lighting apparatus.
