PrevaLED® Compact Z2 | Introduction

1 Introduction

1.1 System overview Well-designed LED outdoor and industry luminaires can

provide the required surface illumination with an improved

uniformity, energy effi ciency and lifetime compared to tradi-

tional light sources. This means that today no compromises

need to be made when choosing LEDs for these applications.

In order to be able to offer outstanding LED modules,

OSRAM capitalizes on its decades of ex perience in the

lighting business. As a result, the PrevaLED® Compact

series is specifi cally designed for outdoor and high-bay

lighting applications and offers very high performance in

a small form factor for a most fl exible luminaire design.

Benefi ts of PrevaLED® Compact LED modules: — Extremely effi cient: With an LED module performance

of up to 140 lm/W.

— Highly reliable: The expected lifetime is 100000 hours

at L80B10, with a max. tc of 80 °C.

— Versatile: A wide range of lumen packages and color

temperatures provides the right products for various

applications.

— Plug-and-play devices: Via the LEDset interface, the

operating current and temperature protection are auto-

matically programmed to the right values.

— Future-proof and interchangeable: Together with

OPTOTRONIC® LED power supplies with LEDset

interface and a dedicated cable, they form a light

engine according to Zhaga book 4.

This technical application guide focuses on the utilization of

the PrevaLED® Compact family within the luminaire design.

2.3 Thermal considerations

Note:A safe and reliable operation can only be realized with

suffi cient thermal management.

PrevaLED® Compact LED modules work with the smallest

thermal losses possible. However, a certain amount of the

LED module’s power must be dissipated through the back

of the LED module as waste heat.

For most applications, passive cooling is suffi cient. In case

of critical environments, an active cooling combined with a

heat sink can maximize cooling.

2.3.1 Heat sink material and sizeFor each LED module, the thermal power to be dissipated

is listed in the corresponding data sheet. All data sheets

are available at www.osram.com.

The selection of a suitable heat sink is normally carried out

through the following steps:

As an example, the diagram below can be used to estimate

the cooling performance of given aluminium heat sinks of

different sizes or to determine the approximate size of a heat

sink required for given ambient temperatures. Simulations

were carried out without any airfl ow turbulence. During

testing, the PrevaLED® Compact LED modules (size 3) were

facing downwards.

Use the estimated RthCA as a target for a possible heat sink profile and material. Depending on the location of the particular

application, it can be an advantage to use black anodized heat sinks to achieve the best heat transfer to the ambient air.

Sample heat sink dimensioningConsidering a 0.3 m2 heat sink, the ta to tc temperature

difference diagram indicates a delta temperature of

approximately 40 °C from the tc point to the ambient

temperatures for a 6000 lm LED module.

In reverse direction, with the given tc temperature of 70 °C

(max.) and an ambient temperature of 10 °C, the resulting

temperature difference of 60 °C can be used to fi nd the

approximate needed heat sink size for stable operation.

For the given temperatures and a PrevaLED® Compact

with 10000 lm, this leads to an aluminium heat sink with

a surface of approximately 0.27 m2.

The list below shows a selection of suppliers of different

cooling solutions:

If, for example, AVC is considered as a supplier, the

following AVC heat sinks could be appropriate for the

approximation above:

2.3.2 Thermal interface material PrevaLED® Compact LED modules installed within a

luminaire with a well-working thermal dissipation system

do not require the use of thermal interface material (TIM).

For demanding applications, however, a TIM can be applied

between the back of the LED module and the luminaire

housing or heat sink. The material has to be as thin as

possible and should reach the desired thermal conductivity

between the surface of the LED module and the surface of

the luminaire housing or heat sink. For this purpose, the con-

tact surfaces should be as fl at and as smooth as possible.

The list below shows a selection of suppliers of different

thermal interface materials.

The temperature at the tc point can be measured by using a

thermocouple which can be glued or soldered to the LED

module. Please make sure that the thermocouple is fi xed to

the tc point with a direct contact. Examples of recommended

thermocouples are shown below.

2.3.3 tc location and temperature measurementThe thermal conductivity between the LED module and the

luminaire housing or heat sink has to be verifi ed by measuring

the temperature at the tc point. The tc point is located on the

back of the PCB, centered underneath the LED’s light-

emitting surface (see fi gure below).

For measuring the temperature while ensuring a good

thermal coupling between the LED module and the heat

sink, it is possible to create a small groove along the top

surface of the heat sink.

If it isn’t possible to reach the back of the PCB, the tem-

perature can be measured between the NTC and the LEDs

with a thermocouple installed at 1 mm from the NTC (see

fi gure below). The temperature measured at this point will

be 2–3 °C lower than the one present at the tc point.

Note: Do not fi x the thermocouple on an electrical contact, as this

could distort the measurements and electrical functionality.

Do not use glue with acrylic compounds for hardening.

The best solution to measure the temperature at the tc

point is to use a sprung thermocouple and insert it inside

the heat sink as shown in the fi gure below.

If a thermal interface material is installed between the LED

module and the heat sink, it is necessary to create a small

hole in it to ensure the direct contact of the thermocouple to

the metal-core PCB.

13


2.3.4 Overtemperature protectionTo ensure best performance and a long lifetime of all

components, PrevaLED® Compact features an embedded

electronic circuit which decreases the input current when

the temperature at the tc point reaches the critical value of

95 °C. The LED module switches off when a temperature of

105 °C is reached and switches back on as soon as the

LED module has cooled down below 90 °C.

Please consider that this protection only works if the

LEDset interface of the PrevaLED® Compact LED module is

properly connected to an OSRAM OPTOTRONIC® LEDset

power supply.

2.3.5 Creepage and clearanceIn order to meet safety requirements during luminaire

design with PrevaLED® Compact LED modules, particular

attention must be paid to creepage and clearance distances

(according to IEC 60598).

The orange-marked areas on the PrevaLED® Compact LED

module shown below are the live parts of the module.

Creepage and clearance distances to these live parts need

to be maintained at all times.

Note:All metal contacts of the electronic components, all test

points and also the copper traces covered with solder mask

have to be considered live parts. The distances between the

mounting screw heads and the live parts also have to be

considered. The distances D1, D2 and D3 to the covered

live parts can be found in the table below.

2.4.2 Insulation coordination for OPTOTRONIC® LED power suppliesOPTOTRONIC® LED power supplies fulfi ll the following

insulation require ments according to IEC 61347-2-13. These

parameters have to be respected in luminaire design. For

further details, please consult the corresponding data and

instruction sheets.

To ensure a long lifetime and a safe handling of the

LED power supply and the LED module, OPTOTRONIC®

LED power supplies are provided with the following

features:

— Overtemperature protection

— Short circuit protection

— Overload protection

For more information, please refer to the corresponding

OPTOTRONIC® data sheets.

* Maximum possible output voltage. The real maximum allowed operating voltage can be lower, see data sheet.

2.4 Electrical considerations

2.4.1 Insulation coordinationAll tests validating the information given in this chapter were

carried out with OPTOTRONIC® LED power supplies.

PrevaLED® Compact LED modules are suitable for working

voltages below 350 V and have basic insulation.

Regarding electromagnetic compatibility, PrevaLED® Compact

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 perfor-

mance criterion A (according to EN 61547). For the fi xation of

the LED module (see chapter 3.1), it is mandatory to use a

fi xing system that maintains proper creepage and clearance

distances from live parts (see chapter 2.3.5).

2.4.4 Electrostatic discharge (ESD)

Note:PrevaLED® Compact LED modules require special ESD-

safe handling procedures in a production environment.

To improve ESD and surge protection of the system, a

thermal interface material can be used between the LED

module and the luminaire housing or heat sink. Details on

installation can be found in chapter 3.

Note:For 3DIMLT and 3DIMLT+, the LEDset protection needs

to be enabled via the 3DIM Tool in the OPTOTRONIC®

confi guration tab. For the LT version, the LEDset protection

is enabled by default. The LEDset protection automatically

switches off the LED power supply in case of a broken wire

to avoid any thermal damage to the LED module due to

high currents.

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 order to comply with the Zhaga standard, we recommend

not to use cables longer than 600 mm. If it should become

necessary to use a longer cable, however, the cabling can

be extended to up to 2 m.

All combinations are affected by the maximum length of the

cabling. The maximum cable length from the OPTOTRONIC®

LED power supply to all LED modules connected in series

must not be longer than 2 m.

17


2.4.5 Current setting and thermal protection PrevaLED® Compact LED modules feature an on-board

electronic circuit that sets the current needed to ensure the

specifi c lumen output of the LED module. In addition, this

circuit monitors the temperature of the module and reduces

the current if required. These two features are available

only if the LED module is connected to an OPTOTRONIC®

LED power supply via LEDset interface.

As a reference, the used fl ux bin is stated on the module label.

Example:For a PrevaLED® Compact LED module, it is required to

have a fl ux of 5400 lm instead of a nominal fl ux of 6000 lm

(-10 %). The nominal fl ux is achieved at Ityp = 500 mA. By

using the graph, it can be easily determined that the LED

current has to be reduced from 500 mA to about 425 mA.

Please refer to the PrevaLED® Compact data sheet for the

Ityp values.

In dependent of the luminaire class, it is highly recommended

to connect the equipotential pin (pink color) to the heat sink

of the LED module. This connection allows for achieving a

better protection of the LED module in case of asymmetric

over-voltages or surges on the main supply (between L/N

and earth (ground)).

Class I luminairesThe PE wire must be connected to touchable metal parts of

the luminaire. It is highly recommended to connect the PE

of the luminaire to the equipotential pin (pink color) of the

OPTOTRONIC® 3DIMLT+ E as well.

Class II luminairesNo PE wire is used in these installations. It is necessary to

connect the equipotential pin (pink color) of the

OPTOTRONIC® 3DIMLT+ E to the heat sink of the LED

module to achieve the best possible surge withstand

capability of the LED module.

3 Installation guide

3.1 Installation of one LED module inside a luminaireThe installation of LED systems (LED modules and power

supplies) needs to be carried out in compliance with all

applicable electrical and safety standards. Only qualifi ed

personnel should perform installations.

The PrevaLED® Compact LED module is fi xed by four M3

screws according to ISO 68-1. These screws should be

fi xed using a torque in the range of 0.3–0.5 Nm. The usage

of a TIM does not change the torque needed.

Note:Excessive torque on the mounting screws may cause

damage to the LED module.

The actual mounting of PrevaLED® Compact is similar to

other LED systems: First the mechanical, then the electrical

connections should be established. For the appropriate

screws and torque levels to mount the LED power supplies,

please refer to the corresponding data sheet.

3.2 Installation of more than one LED moduleinside a luminaireIf more than one PrevaLED® Compact LED module is

installed within one luminaire using the same LED power

supply, the modules need to be connected in series. In this

case, only the LEDset interface of the module reaching the

highest temperatures shall be connected to the power

supply. All remaining wires of the unused LEDset interfaces

need to be insulated (see the illustration at top right).

Lmax. = 2 x 2 m

Each wire has to be

insulated separately

Note:Never wire PrevaLED® Compact LED modules with

different lumen packages to the same LED power supply

as this might destroy the modules.

3.3 IP ratingPrevaLED® Compact LED modules have no special IP rating.

In outdoor use, the luminaire has to provide the appropriate

IP rating for the respective application.

Note:OSRAM products must never be directly exposed to

external infl uences. Always provide adequate protection for

relevant outdoor applications (covers, housings etc.) and

never operate the products in or under water. For more

information on ingress protection, please see the technical

application guide “IP codes in accordance with IEC 60529”

at www.osram.com.

3.4 Protection against corrosionTo avoid corrosion of electronic parts (such as LEDs), it is

necessary to avoid a corrosive atmosphere around the

components. In case of LEDs, e.g. H2S is a highly corrosive

substance which could lead to a drastically shortened

product lifetime. The source for H2S are sulfur-cross-linked

polymers – such as rubber. To ensure the absence of H2S,

we recommend using peroxide-cross-linked materials,

which are available on the market as an alternative to

sulfur-cross-linked versions.

Protection from corrosion by moisture has to be ensured by

selecting and using the appropriate luminaire housing.

3.5 Constant lumen module (CLM)In some applications, it can be useful to compensate the

normal lumen output degradation of LED modules with a

programmed current increase. By means of the 3DIM Tool

software, the operating current can be set to compensate

the lumen degradation over the lifetime, thus lowering the

initial operating current and power consumption and saving

up to 16 % of energy over the luminaire service life.

The following table helps identifying the power level that

has to be set in the OPTOTRONIC® 3DIM power supply:

Note:With a set current exceeding the nominal current of the

LED module, the warranty does not apply.

With CLM, the operating current of the LED module can be

reduced down to 70 % of the nominal current (100 %).

The initial current of a PL-CP-Z2-4000-740 with an active

CLM and a programmed light level of 3400 lm, for instance,

is 17 % lower than the typical nominal value, therefore

requiring a constant lumen module (CLM) starting value

of 83 %.

4.2 Photobiological safetyThe evaluation of photobiological safety is carried out according to IEC 62471:2006 (“Photo biological

safety of lamps and lamp systems”). Following the defi nition of the risk grouping system of the mentioned

IEC standard, the LEDs mounted on PrevaLED® Compact LED modules belong to “Moderate risk (RG2 –

max. exposure time: 59 s)”.

Under real circumstances (regarding exposure time, pupils, observation distance), it is assumed that

there is no endangerment to the eye from these devices. As a matter of principle, however, it should

be mentioned that intense light sources have a high secondary exposure potential due to their blinding

effect.

For this kind of product, the marking “Caution! Possibly hazardous optical radiation emittedfrom this product” is necessary.
