Abstract

An LED lighting appliance (1,26) is provided with; a housing (6) having an open end and a bottom (6a), an LED (2), a lens (3), and a lighting device (8,27) for lighting the LED (2), respectively accommodated in the housing (6), wherein the LED (2) is placed to the bottom (6a) of the housing (6), the lens (3) has a barrel-shape body having a concave incidence end (3a) directly facing the LED (2), a generally flat exit end (3b) exposing to the open end and a sidewall (3c) bulging in a barrel-shaped, wherein the concave incidence end (3a) is defined that a light, emitted from the LED (2) and entered in the barrel-shape body at around the center of the concave surface (3a), performs substantially a total reflection on a major portion of an interface defined by the sidewall (3c), and the reflected light refracts at the exit end (3b) and exits from the barrel-shape body in the receding direction from a central axis of the barrel-shape body.
