ABSTRACT:
Disclosed is a lens for an LED outdoor lamp, and a road lamp, a security lamp, a tunnel lamp, a park lamp, a guard lamp, an industrial flood lamp, and an outdoor lamp using the lens. There is an advantage in that the shape of a light field can be a square shape by controlling light distribution. Brightness is very uniform within a available illumination range, and stray light is hardly generated outside of the range.
