Such helidecks are provided with various lights as shown in FIG. 1 to assist landing when operating a helicopter at night. In other words, a perimeter light 11 for irradiating light upward to express the contour of the helideck 10 and a flood light 11 for irradiating the helicopter in the lateral direction 12 are installed.

On the other hand, only the pedestrian light 11 and the floodlight 12 can not clearly reveal the H mark 13 painted on the upper side and the touch down / positioning making circle 14 Therefore, there was a problem that the pilot of the helicopter could not accurately estimate the landing position.

In order to solve such a problem, a buried illumination unit is further inserted into the lower end of the H mark 13 so as to irradiate light to the upper side of the helideck so that the H mark 13 and the touchdown / So that the positioning marking circle 14 is more clearly shown.

However, the illumination configured on the conventional heli-deck can be used to turn on / off for the purpose of enabling the pilot of the helicopter to measure the correct landing position by making the H mark 13 and the touchdown / positioning marking circle 14 more clearly visible. (ON / OFF) only, and thus, it shows the limitations of its use.
