Passenger Cabin

The passenger cabins on a cruise vessel are designed to offer comfort and relaxation to the residents. On the one hand, the passengers should be made to feel comfortable in their holiday quarters, but equally, it is important that an effective lighting system enables them to enjoy their various activities in the cabin during the course of the day. From getting dressed in the morning to reading a book before switching off for the night, the appropriate lighting setup makes life on-board easy.
Different areas on the ship have special lighting requirements
Feeling comfortable is one of the most important factors for passengers in order to enjoy their cruise journey. This can be achieved by installing appropriate modern lighting solutions in their personal surroundings such as the cabin. This also includes, for example, nightlights for totally enclosed cabins, vibration-resistant luminaires and reduced glare. In order to create a homely ambience, LED luminaires can be equipped with a “dim-to-warm” feature that changes the light colour to a warmer tone when the light is dimmed. To ensure safety on-board, passengers must be able to locate emergency exits quickly throughout the entire ship, even in complete darkness. As a result of these high demands placed on the quality and durability of its products, the Glamox Group operates modern assessment and testing laboratories in Norway and Germany for the simulation of a wide variety of environmental conditions.

Important factors when working with lighting solutions for cabins:
 
- Design, functionality and comfort.
- Mechanical design.
- Low or zero maintenance and reduced power consumption/high energy efficiency

Design and comfort
For an overall harmonised style, the luminaires themselves must also match the interior design of the cabin. Decorative elements for downlights such as trim or decor rings should therefore follow the expectations of today’s designers and architects. Luminaires for different areas of the cabin can be provided in a similar modern style to match the look-and-feel of the cabin. Selecting lighting with an appropriate Kelvin factor will ensure a good balance between light output and human comfort, resulting in a relaxing atmosphere. When dimming is applied, a “dim-to-warm” LED module should be selected to create a warmer light temperature in dimmed conditions. The “nightlight” option sets a very low light level to offer just enough light for orientation in the cabin when a nighttime need occurs. In cabins without daylight, the colour-rendering index (CRI) factor should be above 80 in order to ensure good light quality that is visible to the human eye. The goal of the cabin design should always be to ensure a low uniform glare ratio (UGR). Glare is an important factor in ensuring a comfortable environment. Glamox luminaires have features such as trim rings, décors, diffusers and unique reflector designs to limit this glare. Optimised lighting designs using light calculation programs such as Optiwin® and the application of high quality light luminaires limit the effects of shadowing. Flexible light distribution is provided by using adjustable technologies combined with dimming functions such as analogue, Dali or phase cut.
 
Mechanical design
Low ceiling heights in cabins require low surface mounted or recessed luminaires designed to fit different ceiling thicknesses, which can vary between 0.6mm and 50mm. The Fire classification of ceilings must also be taken into consideration in order to avoid additional fire protection inside ceilings. Glamox recommends the use of dedicated downlights for B15 approved ceilings or surface mounted fixtures if possible. All plastic parts should be flame-retardant materials in order to prevent the spreading of fire and toxic gases. The European standard IEC 60092 requires luminaires installed in cabins to be designed for ambient temperatures up to 45°C. As vibration can generate disturbing noises from the luminaires, it is also important to select marine-approved products that are designed to prevent excessive noise levels. Loose internal wiring due to vibration can be dangerous and could lead to short-circuits. Therefore, the luminaires should be designed according to marine standards. To avoid lengthy installation times and to reduce maintenance costs, it is recommended to use quick connectors. Dust protection is important during the cabin construction phase in order to prevent ingress of dirt and dust to the luminaires, as well as the ingress of dust and insects during normal ship operations.

No maintenance and reduced power consumption
An important requirement on-board a cruise vessel is to install luminaires that are virtually maintenance-free. This reduces or eliminates labour costs, primarily associated with the maintenance, servicing and replacement of luminaires in a cabin. The luminaires should consume as little energy as possible in order to reduce the size of power generators, save energy and to minimise emissions/pollution. The efficiency and life span of LED lighting continues to improve. LED luminaires are virtually maintenance-free, which means that vessels with LED lighting will have lower operating costs compared to vessels with conventional luminaires. In addition, the reduced power consumption of LED lighting onboard has a positive impact on the cruise vessel’s Air Conditioning system, as less heat is emitted from the lighting, which means less AC power is needed and fuel consumption is reduced. The initial investment of the LED installation may be higher than a traditional lighting installation, but the reduced energy consumption and lower maintenance costs of LED lighting means that this price difference will be quickly recouped and payback on the investment is recovered quickly.


In passenger cabins, all lighting products should be designed in accordance with marine standards and regulations.
