Dagsljusavkännande

Dagsljusavkännande, often translated as daylight harvesting or daylight sensing, refers to a system designed to optimize the use of natural daylight within buildings. The core principle is to automatically adjust artificial lighting levels based on the amount of available natural light. When sufficient daylight is present, the artificial lights are dimmed or turned off to save energy and reduce electricity consumption. As daylight diminishes, the artificial lights gradually increase to maintain a consistent and comfortable illuminance level for occupants.

These systems typically employ photosensors or light sensors strategically placed within a room or building. These sensors measure the ambient light and send signals to a control system. The control system then communicates with dimmable ballasts or drivers for the artificial lighting fixtures, adjusting their output accordingly. The goal is to provide a uniform and pleasant lighting environment while maximizing energy efficiency.

The benefits of implementing dagsljusavkännande are numerous. Primarily, it leads to significant energy savings, as artificial lighting accounts for a substantial portion of a building's energy usage. It also contributes to reduced carbon emissions and a more sustainable building operation. Furthermore, by maintaining consistent illuminance, it can improve occupant comfort and productivity by reducing eye strain and creating a more natural and appealing atmosphere. Modern systems can often be integrated with building management systems for centralized control and monitoring.
