Description

Lamp unit for landing induction of helicopter at night}

The present invention relates to a helicopter night landing guidance lamp unit, and more particularly, to a helicopter night landing guidance lamp unit for guiding a helicopter to a helideck installed on a floating structure floating on water such as a ship at night.

In general, offshore plants such as drill ships or FPSO (Floating, Production, Storage and Offloading) or ships that need to stay at sea for a long time must operate helicopters to move personnel. , This requires the installation of a helideck at the bow or stern.

A helideck may generally be composed of a pancake portion forming a deck floor on which helicopters take off and land, and a pancake support portion supporting the pancake portion. The pancake part may be formed by connecting a plurality of planks to each other so as to support the helicopter. The pancake support may include H-shaped beams capable of supporting the pancake portion.

On the other hand, the helideck has a perimeter light that irradiates light upward to indicate the outline of the helideck to help landing when the helicopter is operated at night, and a light that irradiates sideways for embarkation and disembarkation of the helicopter. Lighting such as floodlights are installed.

However, it is difficult for the pilot of the helicopter to determine the exact landing position because the painted H mark and touch down/positioning making circle are not clearly visible with only the perimeter light and flood light. there was As a way to improve this problem, by inserting and installing a recessed lighting unit at the bottom of the Hmark to irradiate light upward of the helideck, the H mark and the touch-down/positioning marking circle are more clearly visible. It is structured to reveal.

However, the lighting configured in the conventional helideck is only on / off for the purpose of revealing the H mark and the touchdown / positioning marking circle more clearly so that the pilot of the helicopter can estimate the exact landing position. It is provided only as a function of a simple driving light, showing limitations in its use.

In particular, in the case of a helideck operating at sea, it is very difficult to safely land a helicopter on the helideck because the helideck itself moves horizontally and vertically as well as the effect of the wind. It is difficult to finely adjust the movement of a floating structure or a ship in which a helideck is actually installed for landing of a helicopter, and currently, it depends on the pilot's piloting skills.

However, sea conditions are basically characterized by strong winds, strong waves, and rapidly changing characteristics, so it is not easy to safely cope with unexpected situations, even if you are a skilled pilot. In particular, the risk is further increased in the case of poor weather conditions or at night.

Therefore, when a helicopter lands on a helideck operated at sea at night, an additional device that can assist in landing more safely is required.

The present applicant has developed a helicopter night landing guidance lamp unit as disclosed in Korean Patent Registration No. 10-2143218 in order to solve the above problems.

a light source unit for laterally irradiating a plurality of guided lights of different colors stacked up and down in order to guide a pilot of a helicopter approaching the helideck of a floating structure on a safe path for landing on the helideck; A housing in which the light source unit is mounted and which guides a plurality of the guided lights irradiated from the light source unit to be partitioned and irradiated in parallel;
The light source unit
A center light source unit installed at the center of the housing to irradiate a first guiding light indicating a safe flight area among the safe routes for landing on the helideck, and installed in the housing to be positioned above the center light source unit, An upper light source unit displaying an upper guide line of the safety route by radiating a second guiding light of a different color from the first guiding light upward to the safe flight area, and installed in the housing to be positioned below the center light source unit, A lower light source unit for displaying a lower guideline of the safety path by radiating a first guiding light and a third guiding light having a different color from the second guiding light downward to the safe flight area;
The center light source part, the upper light source part and the lower light source part
An LED module assembly for irradiating first, second or third guided light and a collimating lens for refracting the first, second or third guided light, respectively,
The collimating lenses are each elongated to have an arcuate curvature with a constant width in the left and right directions intersecting the direction in which the first, second, or third guided light is irradiated, and the central side in the width direction is closer to the front than both sides in the width direction. It is formed in a convex shape to be located in,
A beam width adjusting unit mounted in the housing to be positioned in front of the collimating lens and refracting the first to third guided lights to narrow in width; further comprising,
The beam width adjusting unit
The center light source part, the upper light source part, and the lower light source part are each positioned in front of the collimating lens horizontally, have a constant width in the vertical direction, and are convex in the direction in which the first, second, or third guided light is irradiated. It extends in an arc shape in the left and right directions and has a constant width in the vertical direction to limit irradiation to the outside of the edge side of the area where the first, second, or third guided light is irradiated, and is far from the collimating lens. A plurality of beam width adjusting blocks having beam width adjusting holes formed therethrough so as to expand the recording width and coupled to the housing;
The beam width control block located in the horizontal front of the center light source unit
In a plate shape having a width in the vertical direction and extending in the direction in which the first, second, or third guided light is irradiated so that the first, second, or third guided light is irradiated in a left-right direction disconnected from the outside of the housing. Formed and installed in the beam width adjustment hole to be spaced apart from each other in the left and right directions, the helicopter night landing guidance lamp unit, characterized in that it is provided with a plurality of beam partition partitions partitioning the beam width adjustment hole in the left and right directions. delete delete delete delete
