4. Mounting instructions

MOUNTING INSTRUCTIONS

4.1. General information • During the entire installation process, the personnel must be ESD-protected.

• For effective thermal management, the distance between two LED modules has to be at least 100 mm at a

Ta (ambient temperature) of 25 °C max.

4.2. Assembly of DC24B-XX modules in a mounting profi le

Place the module in the mounting profi le. The module can

be inserted into the mounting profi le from the top or from

the side.

Insert the open ends of the mounting clip into one side of

the mounting profi le, with the nose in the middle of the

mounting clip pointing upwards. Make sure that the

mounting clip is centered above the lateral holes in the

LED module. It must be ensured that a Tc temperature of

75 °C is not exceeded.

1 2

Push the nose of the mounting clip down until it snaps into

the opposite side of the profi le. This can be done by hand

(without tools).

The module is now assembled. Make sure that the V-

shaped angles of the mounting clip are engaged in the

module’s holes.

After assembly, the module can be shifted back and forth

within the mounting profi le.

MOUNTING INSTRUCTIONS

4.3. Fastening cables with mounting clips

1 2

3

In order to avoid shadowing effects in the fi nal application,

the cables between the LED modules can be folded on top

of each other. The ribbon cables may be bended (folded)

only once per position.

Insert the open ends of the mounting clip into one side of

the mounting profi le, with the nose in the middle of the

mounting clip pointing upwards.

Push the nose of the mounting clip down until it snaps

into the opposite side of the profi le. The cable should be

pressed down by both sides of the clip. Repeat this

procedure with all fl at cables between the LED modules.

4

The cables are now fastened.

Please note: The mounting clip is no substitute for a strain relief for the ribbon cables between the LED modules or

for the feed cable of the fi rst LED module. The maximum temperature ranges have to be maintained.

17

MOUNTING INSTRUCTIONS

1 2

3

Grasp the mounting clip with long-nosed pliers, as shown

in fi gure 1.

Carefully pull the nose of the mounting clip out of the

profi le.

The mounting clip is now disassembled. Please check the

clip for deformations before using it again.

Clean the mounting surface on the heat sink with alcoholic

liquid. Rub down to avoid liquid residues on the heat sink.

The DC24B module has to be fastened with M4 screws. It

is recommended to use cylinder head screws. Additionally,

PVC lining disks should be used to protect the copper layer

against mechanical stress.

Together with the heat sink, the DC24B module can now

be mounted onto any kind of surface without the need of a

special thermal interface.

Fasten the module onto the heat sink with both screws.

Dispense heat-conductive material on the mounting surface.

19

1 2

3

Screw the mounting brackets (LD-MB) onto the desired

surface. The brackets have to be in line to each other.

Please use chipboard screws with countersunk head

and a maximum diameter of 4 mm for the fi xation of the

mounting brackets.

Place the mounting profi le on the mounting brackets.

Please use a mounting bracket every 500 mm. At least two

mounting brackets have to be applied for profi les shorter

than 500 mm.

Push the mounting profi le onto the mounting brackets until

it snaps in. Make sure that no pressure is applied on the

LED modules.

4.6. Assembly of the mounting profi le with mounting brackets

4

The mounting profi le is now installed and can be shifted

back and forth on the mounting brackets.

Please make sure that there is enough air space present

around the profi le to ensure an effective thermal manage-

ment. There should be a minimum distance of 50 mm

between two profi les which are mounted in parallel. Both

with and without a mounting profi le, it must be ensured

that a Tc temperature of 75 °C is not exceeded.

MOUNTING INSTRUCTIONS

20

MOUNTING INSTRUCTIONS

1 2

3

Drill M4 threads into the metal surface. The M4 holes have

to be located directly under the countersunk holes in the

DRAGONchain® mounting profi le (DC-MP).

Please use M4 metal screws with countersunk head to fi x

the mounting profi le onto the metal surface.

Please use all available screw holes in the profi le for

mounting.

4.7. Assembly of the mounting profi le on a metal surface

4

By mounting the DC-MP on a metal surface, the heat sink

is extended. Therefore, in combination with a thermal

measurement at the Tc point of the module, the distance

between two modules can now also be less than 100 mm.

A Tc temperature of 75 °C, however, must not be exceeded.

Please make sure that the profi le is mounted on a plain

metal surface. For optimal heat conduction, there should

be no distance between the profi le and the mounting

surface.

When heat sinks, mounting profi les or other systems are

used, it must be ensured that the LED modules are ope r-

ated at a maximum Tc temperature of 75 °C.

Please note:The values on page 21 and above are only an approxima-

tion! The luminance and uniformity results can deviate be-

cause of different application parameters, e.g. refl ection of

the inner surface, parameters of the light-emitting surface

etc. Prior to installation, all applications should be checked

for acceptance in terms of color quality, uniformity, lumi-

nance level and functionality.

6. Thermal properties

THERMAL PROPERTIES

6.1. Casing temperature at the Tc point The casing temperature is the temperature at a defi ned

point on the LED casing, the Tc point. The maximum Tc

temperature is the highest permitted temperature that may

occur at the Tc point under the planned ambient and

operating conditions in the thermally steady state.

If the maximum permitted Tc temperature is exceeded, the

LED module may go into a state in which the load limits on

the module (LED, PCB, optics and electrical components)

are reached. A thermal link between the DRAGONchain®

modules and the mounting surface is not absolutely essential.

6.2. Measuring the Tc temperature

The indicated lifetime can only be achieved if the permitted

operating temperatures at the Tc point are maintained. After

the LED modules have been installed in an application, the Tc

temperature must be measured under the planned ambient

and operating conditions in the thermally steady state. To

do this, attach a temperature sensor to the Tc point with a

suitable adhesive (cyanoacrylate-free). The illustration

below shows the Tc reference point, marked by a small

rectangle on the front of the LED module.

Possible suppliers of such temperature sensors include OMEGA: www.omega.de and B+B Thermo-Technik: www.bubthermo.de

*If the maximum temperature limits are exceeded, the lifetime of the

module will be greatly reduced or the module may be destroyed. The

temperature of the LED module at the Tc point should be measured in

the thermally steady state by means of a temperature sensor or tem-

perature-sensitive sticker in accordance with EN 60598-1. For the

precise position of the Tc point, see the illustration on the left.

8. Notes

NOTES

8.1. General notes • The LED chains must not be used where they may be

directly exposed to the weather without adequate pro-

tection. In outdoor applications, the LED chains must

therefore be protected by suitable housings or covers.

The equipment must not be used in or under water.

• Safe operation is guaranteed only if the LED chains are

connected in parallel. Connecting the LED chains in

series is not recommended. Unbalanced voltage drops

may lead to serious overloads and destruction of individual

modules.

• Make sure to take suitable ESD (electrostatic discharge)

precautions when installing the modules.

• If drivers other than OSRAM OPTOTRONIC® power

supplies are used, the output voltage must be 24 V to

ensure safe operation of the modules.

8.2. Guarantee information

System+ Guarantee from OSRAM. Systematic quality from a single source.LED modules from OSRAM achieve their optimum functio-

nality when operating as a system in conjunction with

OSRAM power supplies, as both components are always

perfectly matched to one another. In addition, OSRAM

offers a guarantee of fi ve years on LMS products used

with OSRAM light management systems or components.

That’s why we offer a comprehensive guarantee for power

supplies, LED modules and LMS components from OSRAM *.

All details on the relevant products and systems, registration

and the general guarantee requirements can be found at:

www.osram.com/system-guarantee

*After registering the system and under certain conditions of use.

8.3. Safety information • The LED module itself and all its components must not

be mechanically stressed.

• Assembly must not damage or destroy conducting paths

on the circuit board.

• The PCBs must be connected ideally to a thermally

conducting surface. Otherwise the lifetime of the

modules shortens.

• The maximum temperature ranges are to be maintained.

• Parallel connection is highly recommended as a safe

electrical operation mode.

• Serial connection is not recommended. Unbalanced voltage

drop can cause hazardous overload and damage the

LED module.

• Observe correct polarity! Depending on the product,

incorrect polarity will lead to emission of red or no light.

The module can be destroyed! Correct the polarity

immediately!

• Installation of LED modules (with power supplies) has to

be carried out with regard to all applicable electrical and

safety standards. Only qualifi ed personnel should be

allowed to perform installations.

• The chain must not be divided.

• Dimming/color control is only possible with PWM.

• Ideally, the DRAGONchain® RGBW/TW is operated by

OSRAM OPTOTRONIC® power supplies and control

gears. Control gears are available with 1…10-V, DALI or

DMX interfaces.

• During dimming operation, the module may produce

interfering noise. In case dimming operation is requested

or required, it is therefore recommended to check the

dimming operation for interfering noise prior to fi nal

installation.

• The power supply has to be short-circuit-proof.

• Please do not look into the LED light source directly and/

or for a longer time.

For the safe application of OSRAM LED modules, it is absolutely necessary to operate them with an electron-ically stabilized power supply which protects them against short circuits, overload and overheating.

OSRAM OPTOTRONIC® electronic control gears guarantee safe operation and comply with all relevant standards.
