Streetlights and Insects Research assigned by the
City of Vienna 2005
Lighttraps Lobau 2005/06 Christoph Unger

Lamps and Catchesat a standardized luminous flux
  • Fluorescent Lamp 1558
  • High-Pressure Sodium Lamp 1813
  • Metal Halide Lamp 1883
  • Metal Halide Lamp blue 4059
  • High-Pressure Mercury Lamp 6176

Nightly migrating Birds
Especially at low visibility and cloudy sky
nightly migrating birds are attracted by punctual
lightsources and the dome light of big cities.
20
Ulrichstein/Hessen 1998
  • In 1998 some 2000 cranes were attracted by the
    floodlights of the castle ruin Ulrichstein in
    Hessen/Germany. Several animals died colliding
    with the castlewalls.

21
Skybeamers
  • Skybeamers affrighten migrating birds and make
    them depart their migrating route. So they loose
    precious energy and time.

22
Multi-storey Buildings

Every year millions of birds die at collisions
with office buildings during migration season.

24
Seaturtles
Hatching seaturtles orient themselfes by the
moon-and starlight rerflected on the sea.
Artificial light on the shore can become a deadly
trap.

25
Toads
  • Toads are attracted by artificial light, where
    they find food but on the other hand easily
    become road casualities.

26
Bats

Insects attracted by streetlights are easy prey
for bats, but on the long term the depletion of
the insect fauna might cause them serious
problems.
27
Nocturnal Mammals

Nocturnal mammals like deer, badgers and foxes
avoid illuminated areas, so they loose living
space.
28
Plants

The biological clock of plants is manipulated by
artificial light. If the shooting of leaves and
blossoms starts too early frost damage may occur.
29
Waterbodies
  • Disturbed by artificial light water flea stop
    grazeing algae at the watersurface, so algae
    flourish.

High pressure mercury lamp
High pressure sodium lamp
31
  • Advantages of high pressure sodium lamps
  • versus
  • high pressure mercury lamps
  • Higher lamp output (30 40 potential energy
    savings)
  • Greater range (especially in misty conditions)
  • Lower maintenance requirements (reduction in dirt
    accumulations caused by insects)
  • Reduced lamp lumen depreciation (loss of power)
  • Lower mercury content (high-pressure NAV lamps)

32
Types of Luminaires
33
Construction of luminaires
  • Shielding light fixtures in species-rich areas
  • Reducing fixture height to 4 meters
  • Using enclosed housings for the lamps
  • Ban on sky-beamers and big-screen illuminated
    advertising systems

34
Operation of luminaries
  • Single-lamp operation of twin-lamp luminaires
    results in up to 50 energy saving
  • Dimming circuit results in up to 50 energy
    saving
  • Luminaire management, e.g. limiting hours of
    operation

35
Bright examples
  • Several communities and municipalities in Austria
    followed the Tyrolean example (including Vienna)
  • Regional government of the country of Vorarlberg
    recommended communities change of lighting
    systems
  • The Austrian railway company accelerated the
    process of lighting change from HQL to NAV
  • The government of the Italian province of South
    Tyrol suggested modifications of lighting in the
    sense of the project
  • Ford company used biocompatible lighting systems
    in new productions facilities
