1. A lens for an LED outdoor lamp, the lens comprising:
- a recess formed at a first side surface of the lens, the recess having a central part at which an LED can be installed and a wall surface, which is an incident surface;
a light emitting surface formed at a second side surface of the lens, the light emitting surface being shaped like a pillow in such a manner that a central part has an arc-shape; and
a perfect reflection surface formed at the first side surface of the lens, the perfect reflection surface surrounding the recess and reflecting light to the light emitting surface.

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.

4. A lighting device comprising:
-
at least one illumination module; and a frame in which the illumination module is installed, wherein the illumination module includes a cooling part, a substrate having an LED matrix formed thereon so as to be attached onto a bottom surface of an upper part of the cooling part through a thermal conductive insulation pad, a PCB having a through-hole matrix so as to be installed at an upper part of the substrate and connected with each LED terminal on the substrate, and a lens cover having a lens matrix so as to be installed at an upper part of the PCB, wherein a recess, which allows an LED of the LED matrix to be installed in an interior of the recess and has a wall surface to be an incident surface, is formed on a central part of a first side surface of each lens of the lens matrix, a light emitting surface, which protrudes to have an arc-shape similar to a pillow, is formed at a central part of a second side surface, and a perfect reflection surface, which surrounds the recess and reflects light to the light emitting surface, is formed at the first surface of the lens, and wherein the LED passes through a corresponding PCB through-hole on the PCB so as to be installed within the corresponding recess. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11)
