                    Optimized Shop Windows Lighting through light sensitive switches




                    Value proposition

                    Main drivers
                    • Shop owners need to light up the shop window at nightfall and save energy by automatically switching off the lighting late at night when the streets are empty.
                    • They also want to prevent the lighting from switching on non-working days.

                    Solution in brief
                    • Programmable light-sensitive automatically switch shop-window lighting according to brightness and/or the time of the day.

                    Value proposition
                    • This solution provides significant energy savings by limiting the shop window lighting only when exterior lighting level is below a pre-defined threshold. Compared to permanent lighting, savings can go up to 50% of the energy consumption .
                    • In addition, IC 2000p+ increases energy savings by automatically extinguishing the lighting when there are fewer passers-by (late at night and on non-working days for instance). These additional savings could be as high as a further 25% when switching the light off from 11:00 p.m. to 05:00 a.m.

                    Main Energy Efficiency characteristics

                    In addition to significant energy savings, Automation provides:
                    • Excellent shop-window lighting as soon as night starts to fall.
                    • The shop-window is lit up after the shop is closed to allow window-shoppers to see the products on display.
                    • Implementation is extremely simple.
                    • The "override" function on the front face enables permanent lighting for cleaning and maintenance services.
