The quest for the perfect port light source
Prismalence light system improves: efficiency, life span, safety and reduces energy costs

Those of us that have spent many a long (and often chilly) night at a port or on a terminal will be aware of the surreal contrast of the light and shadows cast by standard port lighting systems. The lighting looks bright, but it's still difficult to see clearly and there are large areas that the light just doesn't reach. If it's raining and one is tired and straining to see through a greasy windscreen, it's easy to miss what are, in daylight, highly visible objects.

It's not surprising therefore that despite all the health and safely training, there are still embarrassing accidents that afterwards prove difficult to explain. So what's happening here?

Adapting the light to the human eye

During daylight conditions, the maximum sensitivity of the human eye is at 555 nm yellowish-green. During dark conditions, the eye adapts to night vision - a state in which we see fewer colours, but become more sensitive to light overall. The maximum sensitivity of the eye shifts to 507 nm bluish-green and the eye responds not only to brightness, but to the spectral distribution of incoming light. This means that a weak light source of a more yellowish tint may have a greater dazzling effect - reducing night time visibility - than that of a more powerful light source with a bluish tint. Given this information, it seems strange that yellow low pressure sodium lamps are so widely used.

Light sources should also be designed in accordance with human physiology. Logically, lighting for vehicle headlights, plant machinery cargo handling equipment and road or terminal lighting, etc. should have a spectral distribution peaking at bluish-green for maximum visibility and safety with the lowest amount of energy input.

This basic issue has, for a long time, been overlooked. That is, until now. In the quest for the ultimate, the perfect light source would be infinitely small with an infinitely variable brightness, a spectral distribution identical to the sun and the ability to convert 100% of its energy input into pure visible light, without heat loss. This dream may not be true just yet, but the new Prismalence range certainly brings us much closer.

Prismalence - how does it work?

Developed in Sweden, the Prismalence light system is based on a revolutionary technology: a highly efficient broad-spectrum CDM light source and a unique optical system, in which the near parallel light beams from the reflector are evenly distributed across a precisely defined rectangular area by means of an asymmetrical lens.

The resulting visibility, colour reproduction, power efficiency and the long life span makes Prismalence Light Systems the highest quality choice on the market for the ports and maritime industry, where the combination of safety, reliability and energy cost savings can give port operators a huge benefit. The design also goes a long way to improve human night time vision and reduce eye strain.

Other benefits of Prismalence include: -

  • Energy savings of 50% to over 1000%
  • Better light quality through a wide daylight-like spectrum
  • Long life span of the light source, over 16,000 hours, and 30 years for the armature
  • Even spread of light over a precisely defined rectangular area

Prismalence provides a daylight white light that dramatically improves clarity, security and CCTV screen images, while requiring less than half the power. It produces significant energy costs savings, as well as a providing a light unit with a considerably extended life span.

Prismalence units have been approved by the Swedish Highways Authority and are in already in operation at the Port of Rotterdam, and in Amsterdam. The national authority for the Brenner Pass tunnels between Italy and Austria is also installing Prismalence lighting. As well as the Netherlands and other EU Countries, Prismalence products are also in use in Scandinavia, Eastern Europe, East and Central Africa and some Middle East Countries.

Exciting new trials

Glasshouse lightsAs well as one of the large RoRo car carrier operators of in the world, other trials being discussed include : anti terrorist lighting systems for gas carrier operators, customs entry and exit inspection points, high security sites, car and rail terminals, vessel docking spot lights and Ice Breaker search lights. Other industry sectors include: mining, warehousing, agriculture and greenhouses, local government and public buildings and the leisure industry and ski slopes.

Prismalence lighting and its PR is being marketed to the maritime industry by Cameron Maritime Resources.
