They ensure that the team always has a great view. Whether inside or outside, they provide security and remain constant, no matter whether it gets hot, wet or rough. On the occasion of our centenary, we will be presenting our All-Stars team for maritime lighting in more detail.
1919, WISKA begins to manufacture luminaries to meet the new 1917 Handelsschiff-Normenausschusses (HNA) standard. The HNA luminaries were used to protect the incandescent lamps used at the time. These luminaries are excellent for use in extreme conditions, making them the ideal maritime lighting solution.
WISKA presents the SM-Uni-Isolierstof luminaire. It is made of pressed insulating material and has two automatic membrane seals that seal the cable. Simple mounting with only one dowel or one screw ensures quick installation. The luminaire can be ordered with protective glass and protective basket and is suitable for incandescent lamps up to 60 watts. A swivelling lampholder allows easy replacement of the lamp in a compact design.
The first WISKA linear luminaire is registered with the patent office in 1951. The robust and waterproof "Hansa" luminaires are suitable for use on ship walls ceilings, as well as for street lamps. The new fluorescent lamp is well protected against external influences by the housing made of cast light metal. The luminaires are therefore particularly suitable for use in humid and acidic environments and are used in factories, petrol stations and dairy farms.
In 1992, the development of a new corrosion-resistant luminaire, the multi-purpose luminaire 2000, for maritime use is finished. The parts are produced and assembled in-house. The impact-resistant housing made of heat- and seawater-resistant plastic makes the luminaire 2000 ideal for use at sea. Four break-out openings make it possible to use several cable glands for assembly. The luminaire is certified by Germanischer Lloyd (GL) and can be fitted with all common light sources.
In the course of time new light sources are developed. Light-Emitting-Diodes (LEDs for short) now play a leading role in lighting. Low power consumption, high luminous efficiency and a long service life are some of the advantages of LEDs. With the newly developed "LED multi-purpose luminaire 4000", WISKA launches its first LED luminaire on the market. The LED 4000 is resistant to salt water thanks to its plastic components. The multi-purpose luminaire is DNV GL-certified and its reduced design ensures simple and quick installation. The LED multi-purpose luminaire 4000 can be easily supplemented with other high-quality WISKA components, such as the COMBI® series junction boxes or the breathing VentGLAND® cable gland. This makes it an ideal solution for the high demands placed on lighting in the shipping and offshore industries.
The new LED ex luminaire 4200 - A further development of the LED multi-purpose luminaire 4000 for explosion-proof areas (ex-areas). Wherever flammable materials are produced, processed, transported or stored, safety plays a particularly important role. In order to guarantee the highest possible level of safety in these areas. The 4200 luminaire is specially certified for these areas and can be used in Zone 1 hazardous areas. Zone 1 is an area in which an explosive atmosphere consisting of a mixture of air with flammable substances in the form of gas, vapour or mist is likely to occur in normal operation. The luminaire is made of corrosion-free plastic and stainless steel. The reduced design with few components ensures easy mounting, installation and maintenance.
Another new LED development is the floodlight 5000. Previously, aluminium was the preferred material for heat conduction in floodlights. In return for this capability, however, aluminium is susceptible to environmental and mechanical influences. With the aim of solving this problem and driven by many years of plastic expertise, WISKA is developing a completely new LED module with a heat-conducting plastic. The result: a heat-conducting plastic floodlight that is also corrosion-resistant.
Products for hazardous areas have been part of WISKA's fixed product range for many years. The previously available 505 brass light was replaced in 2018 by the further developed 525 brass light. The new feature here is that the light source can be selected thanks to the pressure-encapsulated interior. The product has been recertified for this purpose and has now been approved for the ex type of protection ex de. With its particularly robust construction, the ex 525 is vibration- and shock-resistant, saltwater-resistant, UV-resistant and waterproof.
Following the successful market launch of the LED ex light 4200 and the floodlight 5000, both products will be further optimised in the in-house innovation and development department in 2019. The first prototypes are presented at the Nor-Shipping trade fair in June 2019.
WISKA can look back on a long history of its light products. HNA cast brass luminaires, cast and assembled by WISKA 100 years ago, are still sold today and installed on many ships, while at the same time the use of plastics on board is becoming increasingly attractive and the development of light sources is progressing rapidly.
