darkTECH | The DarkLIGHT Concept

A concept designed to have a discrete lighting setup enough to see the light, without seeing the light source.

DarkLIGHT concept is a means of controlling light from the luminaire whilst reducing glare from light dominating a space, from a source that can only be identified when standing directly under it looking up.

 

DarkLIGHT has 3 main focus areas:

  1.  Up to 30° = Beam Angle Within Light Source
  2.  Between 30° & 60° = Beam Angle Glare Limit
  3.  More than 60° = DarkLIGHT Zone

 

Requirements for DarkLIGHT Limit:

< 200 cd/lm2 above 60-degree viewing angle.

TYPICAL FIELD OF VISION

An average person has :

Horizontal peripheral vision of +-90° per eye.

Vertical peripheral vision of less than 60°

Horizontal Peripheral vision

Vertical Peripheral vision

Requirements for DarkLIGHT Limit:
< 200 cd/lm2 above 60-degree viewing angle.

 

 Standing within the beam of light.
Can see the luminaire & the light source.
(Full light intensities visible).

Standing in the glare limit
Can see the luminaire & the light source.
(Mild light intensities visible).

Standing outside the beam of light
(beyond the darkLIGHT limit).
Can see the luminaire, but cannot determine the light source.
