Marine interior lights provide general and task illumination of cabins and compartments. These light fixtures include dome lights, ceiling lights, downlights, wall lights, reading lights, undercabinet lights, rail lights, floodlights, and spotlights. The interior spaces of watercraft may incorporate different types of lighting to satisfy multiple illumination requirements. General lighting, also referred to as ambient lighting, fills spaces with a soft level of overall light to meet the necessary requirements for easy, hazard-free movement throughout a room and to allow other basic visual recognition. Task lights illuminate specific areas to provide targeted illumination for accomplishing tasks. In some applications, the ambient lighting also works as the primary source of task lighting.
LEDs are the universal choice of light source for marine interior lights. These semiconductor emitters convert electrical power to visible light through injection electroluminescence and photoluminescence within semiconductor packages. This technology allows them to operate more efficiently and last longer than conventional light sources. In addition, the solid-state nature of LEDs provides for greater resistance to shock and vibration. Reduced size and optical directionality enable more freedom in creating form factors suitable for use in ship compartments.
