Circle & H Lighting for Helideck

TD/PM CIRCLE & H Identification Lighting System CAP 437

 
The lighting system is composed by a dashed circle and a H letter
overimposed the corresponding markers of the helideck.
The light elements are extremely thin (20mm) for over–the-deck surface
mounting and resistant to harsh environment and helicopter loads.

A full CAP437 compliant with superior display is achieved by the
special design which guarantees a regular light elements spacing,
free from any junction boxes obstructing the lighting spots.

A double independent power supply circuit and LED bypass devices
ensure that a failure of a single LED has local effect.

Cable penetration in the deck for below-deck cable routing is made
by small circular holes.

The number of the circle element is depending of the D-value. According to the CAP437 chapter 4, the system has to cover between 50% and 75% of the main radius of the painted circle. The following table provides the correct number of light segments for your system.
