A new methodology for the dynamic control of lighting in closed spaces has been patented and developed. The new device can be easily implemented in buildings and allows energy savings up to 85%. Partners to further develop the system and/or to establish commercial agreements along with technical cooperation are sought.
The Challenge
Light is completely essential to perform our daily activities. However, many people are unaware of the high energy consumption because of lighting, especially in buildings. To have the first idea, buildings are 40% of the European energy consumption and 30% of this is caused by the lighting system. Moreover, people are inside buildings for 90% of his life, on average, and this situation is not expected to change in the coming future. Furthermore, the stress in the demand for energy from non-renewal sources is expected to significantly increase the price of electricity in the near future. The optimization of energy consumption is, therefore, a commitment that will inevitably involve lighting systems as it represents an important percentage of the total power consumption.
Technology
The control consists of a position sensor system that is capable to detect the position of users inside the building at any moment. Subsequently, orders for each light are calculated depending on these positions. Additionally, the control includes light sensors that measure incident daylight on the building and dims the generated light according to the regulations.
The current stage of development
The control has been implemented in a working prototype which is based on a rectangular room. The experiments on the prototype were very successful reaching high energy savings.
Applications and Target Market
This control has been developed to be implemented in indoor places. It is highly suitable for large area spaces. Therefore, it is useful in:
· Department stores.
· Universities and schools.
· Offices and industries.
· Hotels and other accommodations.
· Car parks and other underground places.
Innovative advantages
It can be easily implemented in new generation buildings.
Excellent lighting quality.
Energy savings of up to 85%.
Better atmosphere to work.
Able to adapt to different working conditions.
Awareness of the user's position.
