CASEUtilitarian LED lighting.

Lighting of streets and highways of any category, lighting of

bridges and railway platforms.

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 / €).

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

componentsreduction 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.

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

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%).

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.

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»).

Number of lamps per 1 km 37 pcs.

Cost of the lamp* 600 €

Cost of installation* 600 €

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.
