Low Location Lighting (LLL)Example of low location lighting corridor

based on AS-42 Photoluminescent PVC plates

One of the most important elements of safety systems on board ships and offshore drilling platforms is Low Location Lighting. These glow-in-the-dark strips with arrows direct passengers and crew to the nearest Assembly Station and also indicate the location of particular fire safety and first aid equipment (eg. fire-extiguishers, emergency telephones and the overall direction of evacuation).

The use of clearly marked and visible directions limits confusion and the risk of people panicking during emergency situations.

The low location of the photoluminescent strips ie. just above ground level, is due to the fact that during a fire smoke rises gathering near the ceiling. This forces people to move along the ground usually in a crawling or crouched position.

Photoluminescent LLL strips do not need any external energy source. As a result of specific physiochemical properties of strontium aluminate they emit the previously accumulated light becoming visible even in complete darkness.

The A-SPE LLL systems are available in several versions diversified by luminescence strength, length and width of the strips, the material used, application method (ie. how they are fixed in place) and price.

Aluminum Profile for LLL systems

Carrier 1

Aluminum profile

LLL can be fixed in place with the use of a beveled profile so that 50-75mm of the photoluminescent slide-in is visible along all of its length.

Carrier 2

Anchor screws or fixings

LLL strips can also be fixed directly to the wall with appropriate anchor screws. For the effect to be more aesthetic we suggest to cover the heads of the anchor screws with photoluminescent caps after fixing the strips to the wall.

Anchor screws should be purchased separately.

Carrier 3

Self-adhesive mounting foam

The easiest method of fixing LLL strips in place is to stick them to the required surface such as a wall using double-sided self-adhesive foam tape (AS-80*). This method is especially useful when dealing with uneven surfaces or when drilling holes in the given surface is impossible.

* The double sided self-adhesive foam tape can be purchased separately.

Complimentary Stickers for LLL

After fixing the LLL strips in place we mark them with appropriate stickers so that they indicate the actual location of the Assembly Stations, fire-extinguishers and other fire safety and first aid equipment. The list below includes all the most popular pictograms and symbols used as part of the LLL system. We deliver other symbols on demand.
