Collaboration in the science technology of
lighting post-COST529 Stuart Mucklejohn COST529
UK National Representative British Titanium plc,
24 Old Queen Street, London SW1H 9HP, UK
COST 529 Management Committee meeting 02 April
2006, Mierlo, NL
2
Why was COST 529 successful ?
Ÿ Leadership Ÿ Funding Ÿ The people
involved Ÿ Wide range of scientific technical
interests Ÿ Many nations Ÿ Mix of
academia/industry/government laboratories Ÿ
Willingness to exchange information Ÿ
Willingness to host meetings Ÿ STSM
3
How to continue to be successful ?
Ÿ Retain attractiveness to industrial
partners Ÿ Stay relevant and topical energy
consumption environmental aspects (disposal,
re-cycling) quality of light Ÿ Ensure there
are some tangible outputs Ÿ Avoid the
perception of being academic only Ÿ Do not
divorce light sources from lighting Ÿ
Update-to-date web site Ÿ Be known as a
valuable source of information Ÿ STSM
4
Never going to go away topics
Ÿ Fundamental data Ÿ Diagnostic
measurements Ÿ Solving materials problems Ÿ
Evaluating new materials Ÿ Models Ÿ
Education Ÿ Learning Ÿ Training Ÿ
Conferences
5
New opportunities ?
Ÿ Metal halide lamps with ceramic arctubes Ÿ
Corrosion and other aspects of material
transport Ÿ Chemical kinetics Ÿ Vision in the
mesopic region Ÿ Life cycle assessment
(LCA) Ÿ Other European lighting organisations

The COST standard lamp
Ÿ Diagnostics Ÿ Model validation Ÿ
Electrode design Ÿ Lamp ballast
interaction Ÿ Lamp chemistry ? What about
material transport corrosion ? Ÿ Ceramic
standard lamp Design build
or Commercially available product selected

The mesopic range

• Ÿ Photopic Luminance gt10 cd.m-2
• Ÿ Scotopic Luminance lt0.01 cd.m-2
• Ÿ Mesopic Luminance 10 cd.m-2 to 0.01 cd.m-2
• Ÿ Why is the mesopic range important ?
• Road lighting
• Emergency exit route lighting
• Ÿ No system recommended by CIE for mesopic
  photometry
• Ÿ Why not ?
• No internationally accepted eye sensitivity for
  mesopic range
• Ÿ Why not ?
• ? but the response of the eye does change in
  this range
• Ÿ Can we do anything ?
• Yes !!!!

Embodied energy
From the 2004 CIBSE National Conference Delivering
Sustainable Construction David Arnold (Troup
Bywaters Anders) Embodied energy of a
building is the energy used to acquire raw
materials, manufacture, transport and install
building products in the initial construction of
a building Recurring embodied energy of a
building is the energy required for maintenance,
repair and change of use Operating energy of a
building is the energy required to operate the
building (heating, cooling, ventilation,
lighting, powering equipment)

Embodied energy - Lighting
Suggested definitions Embodied energy of a
lighting system is the energy used to acquire raw
materials, manufacture, transport and initially
install all components of a lighting
system Operating energy of a lighting system
is the energy required to operate the system
including the replacement, removal, transport and
disposal of components Broad themes of
sustainability Environment Economic Social
