A plurality of LEDs are arranged continuously in a row and a transparent LED cover is disposed over the front surface of the LEDs. The LED cover extends in the longitudinal direction of the arrangement of LEDs and is curved in an arc shape that is perpendicular to the longitudinal direction of arrangement of LEDs. The cover does not contain light diffusion material, but has a corrugated surface around the arc shape. The corrugated surface extends in the longitudinal direction of the arrangement of LEDs. |
