Why LEDs for Street LightingLightingLightingLighting?

Luminous efficiency (lm/W) of LED reached a level where it

makes sense to use for Street Light Applications

- from technical and economical point of view

LED street lights consume less energy

LED street lights last longer than conventional light sources

6

LED street lights last longer than conventional light sources

LED street lights need less maintenance than conventional

luminaires with bulbs (mercury, sodium, metal halide)

LED street lights can be dimmed

LED street lights produce white light

Less power consumption and less maintenance lead to less

green house gas emissions


…. More advantages of LED-Street Lights

Multi-Layer-Lighting Technology is possible

Modular concept in similar type of fixture to fit most lighting applications

Constant Light Output through Intelligent Degradation Compensation

Thermo sensor to avoid useless degradation

Standard Dimming features – similar to existing fixture types


Standard Dimming features – similar to existing fixture types

Combined post top or side entry mounting & tilting

High quality materials & high end design

Easy replacement of power supply

Dark Sky Friendly

Capsulate & Maintenance free light units (housing LED- modules)

Different Lighting Technologies

Clip-In Off-The-Shelf Modules

Lens Systems


Lens + Reflector systems

Clip-In Off-The-Shelf Modules

+ Cheap solution

+ Capsulated LED-Module

+ Easy exchange of LED-modules inside LED-unit

- No capsulation of the LED-Unit causes ingress of dust, insects etc.

- Less optimized heat management → increased degradation


- Less optimized heat management → increased degradation

- Less efficient light performance than other systems

Application in traditional lighting fixture as “retrofit” from bulb to LED

Lens Systems

~ Each LED or LED-cluster covered by one lens

~ available in several levels of quality and prices

+ Good light distribution (directed light)

+ Customized light distribution available by some manufacturers

- lower quality lenses will show increased cloudiness in short time,


caused by influence of temperature and UV radiation (> 4500°K)

~ Quality of heat management depending on system design – coupling

of LED-PCB to the housing

Lens + Reflector Technology

New and quite revolutionary technology

Each LED is lighting the entire street

surface

By adding more LEDs the light level on

the street is increased – Multi Layer

Lighting Technology


Lighting Technology

Several LEDs are put together in a so-

called light module

No dark spots on the surface!

By using more light modules the

lightoutput can be adopted to the

requirement acc. EN13201

Multi Layer Lighting


Capsulated Light Unit

Light modules fully capsulated

during production process

No water, dust, sand or any

other environmental material

can ingress into light unit


This ensures that the light

output is not decreased and

that the light unit itself is

maintenance free

Intelligent Degradation Compensation

Sustainable mechanical, thermal and electronic design is the key

to keep degradation of the LEDs to an unavoidable minimum

The small amount of degradation that appears can be fully

compensated by intelligent degradation compensation systems

This ensures constant light output after years of operation as


This ensures constant light output after years of operation as

on day one at installation

To prevent damages to the LEDs by high temperatures (e.g.

switching on during hot daytime for checking) LED Street Lights

must be equipped with thermal sensors that automatically dim

down the luminaires before damage can occur to the LEDs

Dimming

Modern LED Street Lights are equipped with the following standard

dimming features, that are most commonly used:

Voltage Drop

Switched Phase

Ensures full replacability of conventional luminaires


Ensures full replacability of conventional luminaires

Gives additional energy savings

Further decreases degradation of LEDs

Mounting Options in Europe

Combined post-top and side entry

Pole diameters from 42 to 76mm

Easy Replacement of old luminaires (retrofit)


Replacement of Power Supply

Some LED Street Lights

provide easy and fast access to

the power supply which can be

easily replaced even during

operation as the power supply is

fully capsulated within a plastic


fully capsulated within a plastic

box

Dark Sky Friendlyness


Dark Sky Friendlyness

Light pollution has become a serious issue already

LED-Streetlights MUST NOT emit ANY light above the horizon, to

be dark-sky-friendly and to be compliant already today to the

requirements of tomorrow


Retrofit Market vs. New Installations

� Only the luminaires are replaced

� Poles & Cables remain

New Installations

� Complete Lighting calculation is

done (light level, uniformity, …)

� Only 10-20% of costs are above the surface (luminaires & poles)
