| Abstract |
In this paper, we studied the customized design for LED berth light of ship cabin based on the user's behavior pattern analysis and lighting environment investigation. We studied the lighting design target, product design, design simulation, preparation of a prototype with a bidirectional radiation luminaire, and then measured and analyzed the lighting characteristics and lighting atmosphere. Upward lighting provides indirect illumination through the reflection to ceiling of the bed for the rest or sleep activities, whereas downward lighting provides enough illumination to the bed plane for the working or reading activities. In addition, illuminance and correlated color temperature (CCT) control was enabled by adopting warm and cool white LEDs with dimming. The prototype had the enhanced performance with α, δ, θ brain wave effect depending on the user's behavior pattern and the improved berth lighting atmosphere was closely matched to user's behavior patterns. The prototype was shown the better lighting performance with high flux, reduced glare and increased lighting efficiency compared to the conventional lighting fixtures. |
