Abstract
An LED bar lighting and an exhibition includes a receiving chamber and at least one LED bar lighting. The receiving chamber includes a mounting reference line. Each of the at least one LED bar lighting includes a bar house, a plurality of LED chips, and a lens column. Each of the LED chips includes a chip optical axis. The lens column includes a lens optical axis parallel to the chip optical axis, a first light emitting surface intersected with the lens optical axis, and a second light emitting surface. The first light emitting surface is a condensing lens. The second light emitting surface includes a convex lens, and a plane surface located between the first light emitting surface and convex lens. An angle between the lens axis and the mounting reference line in the cross section perpendicular to the axial direction of the bar house is an acute angle.
