16 General application examples
16.1 Lighting of billboards and neon advertising signs
Billboards should be lit up even at night so they are easy to see and grab people's attention. The
SELEKTA top2 automatically controls the lighting of company logos, neon advertising signs and
information boards.
o
Billboards can be lit up 1 hour before sunset (offset -60 minutes) to ensure they are well
visible.
o
To save energy, lighting for advertising signs can be switched off in the early hours of the
morning from 1:00 AM to 4:00 AM, for example, using the night switch-off function.
16.2 Street and facade lighting
If streets are lit up at night, it makes things safer for all road users. Illuminated facades make city
centres light and attract people to look round the shops during the evening.
Street lighting is automatically switched on at sunset and off at sunrise.
o
Tunnel lighting special application : Astro mode is used in reverse here.
Viewing conditions change as you enter a tunnel and the human eye has to get used to the
lower level of light. To ensure the difference in brightness is not too great when entering a
tunnel at night and entering it during the day, only every second lamp in the tunnel is switched
on at night and all lamps are switched on during the day, for example.
In the interests of cost, facade lighting is usually switched off between the hours of 1:00 AM and 4:00
AM; it is then switched back on at 6:00 AM until sunrise.
16.3 Car park lighting
Car parks are lit up to make them safer and suitable for use at night. SELEKTA top2/top3 can be used
to automatically control the lighting of car parks at night. Car park lighting is switched on at sunset and
off at sunrise.
