The present invention relates to an LED lens for a floodlight of a signboard, which can diffuse light from an LED light source to the overall surface of a wide signboard evenly. The LED lens, which is prepared over an LED of a floodlight of a signboard to diffuse light from the LED to the signboard evenly, comprises: a bottom surface being symmetrical to a y-axis and including a light entrance surface into which the light from the LED comes; a light exit surface being symmetrical to the y-axis and configured to diffuse the light that was emitted from the LED and came into the light entrance surface to both sides of the y-axis; and a reflector unit being symmetrical to the y-axis and provided at the front of the light exit surface to reflect some of light exiting from the light exit surface to an upper portion of the signboard, wherein an x-axis is a transverse axis horizontally crossing an optical axis of the LED and the y-axis is a longitudinal axis vertically crossing the optical axis.
