People in a ship’s office work during the day and at night, so lighting installed in these areas must provide good light quality.
Different areas on a ship require special demands on lighting
Just like all areas onboard a Navy or Marine vessel, the office has particular demands on the installed equipment. Working with computers or reading demands glare-free lighting solutions.
Important factors when working with lighting solutions for offices:
- Light quality (colour rendering; task lights to illuminate desks) and glare (Uniform Glare Ratio).
- No maintenance and reduced power consumption (high energy efficiency).
- Mechanical design/impact resistance.
In an office the light output quality is critical due to visual perception and to allow people to distinguish between different colours and details. The colour-rendering index (CRI) should be above 80, the lighting illumination level around 200 lux in order to be able to differentiate and see true colours. To avoid shadowing and to reduce glare (UGR, uniform glare ratio) luminaires with homogeneous light distribution should be installed.
Lighting with a dimming function should be considered for optimal light in the office.
No maintenance and reduced power consumption
Maintenance-free, easy installation and various mounting options ensures 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. The efficiency and operating life of LEDs continues to improve, and LED luminaires are virtually maintenance-free. This means that vessels with LED lighting will have lower operating costs compared to vessels with conventional luminaires. The initial investment in an LED installation may well be higher than that of a traditional lighting installation, but the LED’s lower energy consumption and maintenance costs means that this price difference is quickly recouped and payback on the initial investment is recovered quickly.
Using the correct combination of materials in the luminaire is important in order to ensure robustness and a long operating life. The use of aluminium is vital for LED lighting products to ensure sufficient cooling for continuous operation, low maintenance and a long operating life. Easy installation and various mounting options ensures flexibility and time savings. Friction locks on task lights should be considered in order to avoid unwanted movement of the task light during rough seas or poor weather conditions.
We always recommend Navy and/or Marine-approved lighting products in an office.
