Progress in lighting technology comes in waves: As the LED is emerging as the winner from the current wave, the digital transformation is pushing the limits of technical possibilities of lighting once more, as it gives access to more degrees of freedom in lighting. Advances over the last decade have significantly expanded the scope of lighting technology: ‘Intelligent Lighting’ yields several new opportunities. Through the advantageous properties of LEDs electric light will be a carrier for optical wireless communication. It finally will provide its users the lost qualities of a natural dynamic light environment as a surrogate of sunlight with all its stimulating effects, thus a ‘Human Centric Lighting’ addressing the biological needs of a ship’s crew with limited access to daylight, increasing their well-being, health and performance on the job.
