Dining on a cruise vessel is a joyful celebration in the truest sense. To amplify this experience with all senses, the lighting installations in a restaurant or dining area should provide atmospheric lighting and turn the location into a cozy, relaxing ambience.
Following its use as a dining area for passengers, the process of then rearranging tables and cleaning the restaurant areas requires a very different lighting scenario with higher brightness in all corners and a light temperature of 4000 Kelvin.
Different areas on a ship require special demands on the lighting
In order to enjoy the lunch or dining experience, one of the most important factors for the passengers is that they feel comfortable and relaxed at all times. This can be achieved by installing suitable lighting and modern designs of luminaires in their surroundings. For example, this may also include installing vibration-resistant luminaires or lighting with reduced glare light output. As a result of the 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 restaurant/dining areas:
- Functionality and comfort.
- Mechanical design/impact resistance.
- No maintenance and reduced power consumption (high energy efficiency).
- Flexibility in setting different lighting scenarios e.g. dinner, breakfast or post-cleaning process.
Functionality and comfort
For a harmonised style in the restaurant areas, the luminaires must match the overall interior design, including both ceiling- and wall-mounted luminaires. Light fittings for different areas in the restaurant can be provided in the same style. A suitable Kelvin factor for lighting ensures a good balance between the light output and comfort for human eyes. Indirect lighting can be achieved by using LED strips, either in fixed colours or as RGB-application. Flexible light distribution can be provided using adjustable technology combined with dimming functions such as analogue, Dali or phase cut. When dimming is applied, a “dim-to-warm” LED module should be selected in order to create a warmer light temperature in dimmed conditions. This results in a cozy and relaxing atmosphere. The colour-rendering index (CRI) factor should be above 80 in order to provide good quality light. Glare is an important factor in ensuring a comfortable environment for passengers. Glamox luminaires provide features such as trim rings, decors, diffusers and unique reflector designs to limit this glare. Lighting designs can be optimised by using light calculation programs such as Optiwin® and by using high quality light luminaires that will limit the effects of shadowing.
Low ceiling heights in the restaurant areas may require low surface-mounted or recessed luminaires that are designed to fit different ceiling thicknesses. All plastic parts should be flame-retardant materials to prevent fire and toxic gases from spreading. The European standard, IEC 60092, requires that lighting installed inside restaurant and dining areas should be designed for ambient temperatures of 45°C. As vibration can cause disturbing noise levels from the luminaires, it is also important to choose marine-approved products that are designed to prevent noise (i.e. vibration-resistant). Loose internal wiring due to vibration is dangerous and can cause short-circuits. The luminaires should therefore be designed according to the relevant marine standards. To avoid lengthy installation times and to reduce maintenance costs, Glamox recommends the use of quick, plug-and-play connectors. Dust protection is also important during the ship construction/fitting phase in order to prevent dirt getting inside the luminaires, as well as later during normal ship operations to prevent the ingress of dust and insects to the fixtures.
No maintenance and reduced power consumption
Maintenance-free, easy installation and various mounting options ensure flexibility and time savings, primarily because some lights may be located in areas that are difficult to reach or often with no access at all. The luminaires should consume as little energy as possible in order to reduce the size of power generators, to save energy and to reduce pollution/emissions. Therefore, LED lighting is recommended. LED luminaires are virtually maintenance-free, which means that cruise 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.
All lighting products in a restaurant area should be designed in accordance with marine standards and regulations.
