STREETLIGHT IP G1 | Introduction
1 Introduction
LED systems are able to exploit their inherent advantages
in street lighting and outdoor lighting: They provide the
required lighting level with homogeneous illumination and
consume less energy than traditional lamps. The long life-
time of LEDs with only low decreases in luminous fl ux are
also ideal for the long life cycles needed in outdoor lighting.
With STREETLIGHT IP, OSRAM provides an innovative,
IP66-protected LED module for street lighting, enabling
extremely short luminaire development cycles. The innova-
tive refl ector concept ensures standard-compliant lighting
(in accordance with EN 13201) while providing a very high
quality of light and high effi ciency, as well as a future-proof
platform for further advancements in LED technology.
Benefi ts of STREETLIGHT IP — Fast time to market thanks to easy design-in
— Typical effi cacy: 85–100 lm/W (including cover,
even within demanding lighting applications)
— High quality of light, low glare, no scattered light
— Very long lifetime: 100,000 hours with L80/B10
— Very effective thermal management due to uniform
heat dissipation over the complete rear surface
— Plug-and-play: Via the LEDset interface, the operating
current and temperature protection are automatically
programmed to the right values when used with an
OPTOTRONIC® 3DIMLT+ LED driver.
This technical application guide focuses on the utilization
of the STREETLIGHT IP family in luminaire design. Further
information (such as data sheets, EULUMDAT, CAD fi les)
is available at www.osram.com.

STREETLIGHT IP G1 | STREETLIGHT IP design-in
By design, STREETLIGHT IP LED modules offer a very
quick and relaxed luminaire development process, solving
many potential issues already on module level (e.g. optics,
IP, IK, heat dissipation etc.).
3.1 Optical considerationsSTREETLIGHT IP LED modules come with dedicated light
distributions and in various color temperatures. As far as
the optical concept is concerned, the module consists of
several LEDs mounted in groups beneath the refl ector
array, guiding the light to the road surface.
Once more effi cient components are available, this concept
allows reducing the number of LEDs without compromising
the light distribution.
Currently, there are three different color temperatures
available: 3000 K, 4000 K and 5000 K. The nominal color
rendering index (CRI) is 70 for all LED modules. The color
variation from module to module is inside two ANSI bins.

3.2 Mechanical considerationsSTREETLIGHT IP LED modules consist of a metal-core
PCB which is built into an aluminum housing and covered
by a polycarbonate (PC) cover which ensures IP66
protection for the LED module and the refl ector.
3.2.1 LED module dimensionsDetailed CAD models can be downloaded at
www.osram.com.
In addition to the mounting holes depicted above, the LED
modules have four blind holes on the back, which allow an
easy connection to the heat sink using four self-cutting M4
screws.
Note:Mechanical stress can damage the module.

3.2.2 LED driver dimensions 3.3 Thermal considerations
Note:A safe and reliable operation is possible only with suffi cient
thermal management.
While STREETLIGHT IP LED modules operate with the
smallest thermal losses possible, a substantial amount of
the LED module’s power must nevertheless be dissipated
through the back, as specifi ed below.
The thermal power is spread evenly over the aluminum
housing of the module, so that it can be easily cooled in a
passive way.
For each LED module type, the thermal power has to be
dissipated, as listed in the following table:
3.2.3 IK ratingIn compliance with EN 62262, STREETLIGHT IP LED modules
have an IK rating of IK08 on module level. Even higher
ratings can be achieved within the luminaire.

3.3.1 Location of the tc point and temperature measurementThe heat dissipation between the LED module and the heat
sink (often the luminaire housing) has to be verifi ed by
measuring the temperature at the tc point with a tempera-
ture sensor (see fi gure below), according to EN 60598-1 in
thermally settled conditions.
LED module with four refl ector clusters
LED module with two refl ector clusters
The following table provides the operating current limit for
using the module without an additional heat sink, thus
staying below the rated maximum tc temperature of 68 °C.
Apart from the fi xed temperature protection depicted above,
an individual protection logic can be defi ned via the 3DIM
Tool software. The NTC used on the STREETLIGHT IP
module is "EPCOS B57423V2473H".
Further information on the usage and capabilities (e.g.
constant lumen function) of the 3DIM Tool software can
be found at www.osram.com/3dim.
3.3.2 Overtemperature protectionTo ensure the best performance and a long lifetime of all
components, STREETLIGHT IP LED modules feature an
embedded electronic circuit which decreases the input
current when the temperature at the tc point reaches 77 °C.
The LED module switches off when a temperature of 89 °C
is reached and switches back on as soon the LED module
has cooled down below 84 °C.

Note: Exceeding maximum ratings for operating and storage
temperatures will reduce the expected lifetime or destroy
the LED module.
Please consider that this protection only works if the LEDset
interface of the STREETLIGHT IP LED module is properly
connected to an OSRAM OPTOTRONIC® LEDset driver
with NTC terminal.

3.4 Electrical considerations
3.4.1 Insulation coordinationAll tests validating the information given in this chapter were
done with OPTOTRONIC® LED drivers. STREETLIGHT IP LED
modules are suitable for working voltages below 350 V and
provide basic insulation.
Regarding electromagnetic compatibility, STREETLIGHT IP
LED modules show a performance criterion A for contact
electrostatic discharge of up to 4 kV and for air electro-
static discharge of up to 8 kV (according to EN 61000-4-2).
Fast transient disturbance tests were also passed with per-
formance criterion A (according to EN 61547).
3.4.2 Insulation coordination for OPTOTRONIC® LED driversOPTOTRONIC® LED drivers fulfi ll the following insulation
requirements according to EN 61347-2-13. These para-
meters have to be respected in luminaire design. For further
details, please consult the data and instruction sheets.
To ensure a long lifetime and a safe handling of the LED
driver and the LED module, OPTOTRONIC® LED drivers
are provided with the following features:
— Overtemperature protection
— Short circuit protection
— Overload protection
For more information, please consult the corresponding
OPTOTRONIC® data sheets.
* Maximum possible output voltage. The real maximum allowed operating voltage can be lower, see data sheet.

The wire cross sections which have to be used with
OPTOTRONIC® LED drivers are listed in the following table.
For an easy connection of the LED driver and the LED module,
the STREETLIGHT IP LED module comes with pre-stripped
cables. All fi ve wires (for LED driver and LEDset) have the
same colors as the OPTOTRONIC® output cable clamps.
Ensure that the LED module is correctly connected to the
LED driver. The cable is rated for an ambient temperature of
-40 °C to 80 °C.

3.4.4 Electrostatic discharge (ESD)STREETLIGHT IP LED modules require special ESD-safe
handling procedures in a production environment.
3.4.5 Current setting and thermal protectionSTREETLIGHT IP LED modules feature an on-board
electronic circuit that sets the current needed to ensure
the nominal lumen output of the LED module. In addition,
an NTC monitors the temperature of the module and
causes a reduction of the current, if required. Both features
are available only if the LED module is connected to an
OPTOTRONIC® LED driver via LEDset interface with NTC
terminal.
Note:The LEDset protection has to be enabled via the 3DIM Tool
in the OPTOTRONIC® confi guration tab. The LEDset pro-
tection automatically switches off the LED driver in case of a
broken wire to avoid any damages to the LED module due to
overheating.
In case LED+ or LED- is disconnected during operation,
disconnect the mains voltage and wait at least 20 seconds
before reconnecting the LED module. In general, the maxi-
mum cable length from the OPTOTRONIC® LED driver to all
LED modules connected in series must not be longer than
2 m. In case investigations on longer cables are needed,
please contact OSRAM application engineering for support.
Note: Thermal protection won’t be active if the LED module is not
connected to the NTC terminal of the OPTOTRONIC® LED
driver. All information necessary to use the LED module with
other drivers can be found in the STREETLIGHT IP data sheet.

the luminaire. It is strictly recommended to connect the PE
of the luminaire to the equipotential pin (pink color) of the

Class II luminairesNo PE wire is used in these installations. It is strictly
recommended to connect the equipotential pin (pink color)
