Utilitarian LED lighting. Lighting of streets and highways of any category, lighting of bridges and railway platforms.

1. DEG Licht GmbH, Germany.
CASE
Utilitarian LED lighting.
Lighting of streets and highways of any category, lighting of
bridges and railway platforms.

2. The modern market offers countless street lamps. The price range is also very wide.
However, the strong problem remains related to price/quality ratio: light-technical
parameters, reliability, service life - important parameters that many manufacturers simply
do not pay attention to:
Modern outdoor lighting
Outdoor LED luminaires should have proper
IDC, which allows their use for lighting of class A
highways and federal roads.
The design of the lamp must have
characteristics capable of providing protection
against aggressive environment, minimizing the
risk of affect to electronics and the LEDs.
Service life of the lamp – the real one often
does not comply to that claimed by a
manufacturer.
Efficiency and economy: the ratio of lumens/watt;
lumens/dollar: many manufacturers with high
performance of lumen/watt (100 or more) do not
mention the ultimate value of a unit of light (ie,
lumens / €).

3. PROBLEM 1. Aggressive external environment: rain, dust, soot, exhaust gases,
particles of oil, antifreeze, unburned fuel.
Aggressive environment affects the body of the lamp, electronics, and optics (penetrating into the internal cavities).
premature failure of electronic
components
reduction in the efficiency of the
optics
destruction of internal elements of the
luminaire (even appearance of the phase
voltage on the housing).
Standard LED floodlight
• Aluminum alloy housing is not protected by oxidation.
• Direct contact between different metals accelerates
electrochemical corrosion.
• Simple pressurization of the internal part by sealants.
• Standard optics PMMA или PC.
• Unprotected electronics assembly.
«Four light» solution
• Double thickness aluminum alloy housing or oxide coated.
• All contacts between different metals pass only through
insulating spacers.
• Soft mount a protective polycarbonate glass with a relief
valve.
• Optics is not used. The use of high-quality reflectors.
• Electronic circuit boards are covered with a special varnish.
• Compliance with IP65.

4. PROBLEM 2. Distribution of light
uneven or stray light. decrease in efficiency of useful light flood
Standard LED floodlight
• Non compliance/non full compliance with the recommended
Luminous Intensity Distribution Curves (IDC).
• The high proportion of stray light.
• High level of light pollution, ecological damage.
• Stray lighting of dwellings.
«Four light» solution
• Full compliance with the claimed IDC.
• The choice between 4 IDC types for each particular object.
• The special shape of the floodlight and reflectors for an
optimal uniform light flux.
Excessive light flood.
Increase in light pollution level damage to light ecology of
the city

5. PROBLEM 3. Blinding of drivers
Exceeding the threshold brightness --- >> Temporary blindness of the driver --- >> extremely dangerous situation on the road.
Standard LED floodlight
• The use of powerful diodes and secondary optics creates a
highly efficient flow of light.
• The absence of a blend, a simple form of the housing leads to
the direct illumination of the driver's eyes above the threshold
brightness.
DEG Licht solution
• The side of the lamp shields the LEDs light from getting
into the driver's eyes. With this technical solution, the driver
sees only a minimal part of the luminous surface of the
lamp, with no loss of quality of illumination of the road
(average luminance, average brightness and uniformity of
illumination).
• Threshold increment of brightness is set to 8%, which
means there is no blindness (at demand of ≤15%).

6. PROBLEM 4. Energy efficiency (increased light output). Low color rendering index
Low rate lm/W = inefficient use of electricity.
The lower the color rendering index, the less reliable the
human eye perceives the situation on the road.
Standard LED floodlight
• The use of cheap LEDs light with output less than 120
lm / W.
• The loss on the secondary optics up to 10% of the
luminous flux.
• The use of super bright diodes with a temperature
above 6000° K .
• The use of diodes with a low color rendering index.
DEG Licht solution
• LEDs from the leading manufacturer CREE are used, the series
XML with light flux 160 lm/W and color temperature 3000 to
6000 K.

7. PROBLEM 5. Economical efficiency.
Economical efficiency ≠ price of the lamp.
Economical efficiency
• efficiency (lm/W)
• Installation cost
• the frequency and cost of maintenance
• number of lamps per object
• «price for lumen» (or «€/lumen»).
«DEG Licht» solution
Number of pillars per 1 km 18,5 pcs.
Number of lamps per 1 km 37 pcs.
Cost of lighting installation* per
1 km
33 500 €
Cost of the lamp* 600 €
Cost of installation* 600 €
Energy cost for 10 years*
*The calculations shown are approximate.
For each particular project characteristics
may differ.
30 000 €

8. PROBLEM 6. Vibration and wind affect over the lamps functioning
Vibration effects from vehicles and other external factors
Strong wind creates a
variable load on the lamp
decrease in the stability of
its fixation
Standard LED floodlight DEG Licht solution
• Lightweight constructions
of the housing (in order to
save materials) are more
susceptible to the effects of
vibration.
• Weighted design of the
luminaire is less prone
to the effects of
alternating wind loads.
