摘要： A light emitting unit may include a housing having a bottom portion parallel to an xz plane and an opened top opposite to the bottom portion, a light emitting chip on the bottom portion and generating light, and a lens which overlaps the opened top of the housing. The lens may have a convex structure with respect to the xz plane when viewed from a cross section parallel to an xy plane and a concave structure with respect to the xz plane when viewed from a cross section parallel to a yz plane.
