Light control for outdoor lighting

Outdoor lighting makes our streets and outdoor environments safer and more pleasant, but it is also a large energy consumer. If we turn off the light completely, people will feel unsecure. A good way to handle this challenge is to use dimmable LED lighting that will reduce energy consumption without compromising on safety.

Glamox offers a system where all the light control components are integrated in each luminaire without any need for external accessories to make the lighting control work. We call it Glamox NightDim and there are 2 different pre-set modes.

Mode 1 (ND1): Dimmed down 50% for 6 hours starting from centre point

Normally, the existing system is already controlled by either a timer or a twilight sensor. The NightDim calculates the light cycle’s centre point and dims the light down to 50 % in a period of 6 hours after the centre point.

Example

October
  • In October a street is illuminated for 14 hours, from 6 p.m. to 8 a.m.
  • The centre point is at 1 a.m. (14 hours divided by 2 equals 7 hours which places the centre point 7 hours after 6 p.m.).
  • Light will be turned on 100% at 6 p.m.
  • • At 1 a.m. the lights are dimmed to 50%.
  • At 7 a.m. the lights are back to 100 %
  • At 8 a.m., the lights are turned off.


June

  • In June the same lights are burning for only 6 hours from 10 p.m. to 4 a.m.
  • The centre point is at 1 a.m. (6 hours divided by 2 gives a centre point 3 hours after 10 p.m.)
  • At 10 p.m. the light will be turned on 100%.
  • A 1 a.m. the light will be dimmed to 50%
  • At 4:00 a.m. the light will be turned completely off.

Mode 2 (ND2): Dimmed down 50% for 8 hours, starting 2 hours before centre point

Normally, the existing system is already controlled by either a timer or a twilight sensor. The NightDim calculates the light cycle’s centre point and dims the light down to 50% for a period of 8 hours starting 2 hours before the centre point.

Example 2

  • In October a street is illuminated for 14 hours, from 6 p.m. to 8 a.m. 
  • The centre point is at 1 a.m. (14 hours divided by 2 gives a centre point at 7 hours after 6 p.m.).
  • The light will be turned on 100% at 6 p.m.
  • 2 hours before centre point (11:00 pm) the light will be dimmed down to 50%.
  • At 7 a.m. the lights are back to 100 %
  • At 8 a.m. the lights are turned off.
