Disclosed is a high efficiency traffic sign which uniformly emits a light using low electric energy while being applied with an existing photovoltaic generation module. The traffic sign according to the present invention comprises a circular rear plate, a rim plate formed on the front side of the rear plate, a sign plate attached to the front side of the rim plate, and LED lamps installed inside the sign plate, wherein the LED lamps are turned on by the electric energy produced in the external small photovoltaic generation module. The LED lamps are circularly arranged inside the rim plate, and a conical reflection plate is attached to the front side of the rear plate, wherein the reflection plate has a height becoming higher toward the central portion of the sign plate. The reflection plate is manufactured by bonding a cut groove which is shaped into a fan from the central portion of a disc to one side of the disc. |
