  • Page 9: System Description

    A signal output from the TunnelTech 601 is fed to a suitable controller to adjust the level of light intensity inside the road tunnel to the light intensity outside, The TunnelTech 601 Luminance Photometer fully complies with CIE recommendations for road tunnel lighting control.

  • Page 10: Principles Of Operation

    Operation and Maintenance 2 Principles of Operation The TunnelTech 601 is built around a metal/glass encased reverse biased silicon diode photocell that determines the luminance levels of a given area, together with an eye response optical filter with a 20° viewing angle. Optical filters are used to provide measurements of luminance to the required standard human visible spectral response.
