Important

Please take the time to read this installation guide before you install this Philips LED product and driver. The guide

contains important information regarding installation and operation.

Warranty

Warranty only applies when the appropriate Philips

LED driver and Philips cabling (as described in this

guide and leaflets)

are used. Please visit our website www.philips.com/

OEM or contact your local sales office for more

information.

Warnings and system restrictions

• Do not switch on the LEDFlex S when on the reel.

• This product may require a heatsink.

• The installation guide does not supersede local or

(inter)national regulations for electrical installations.

• This Philips LED product and LED driver must be

installed by a professional electrician in accordance

with the applicable and appropriate electrical codes

and the instructions provided by Philips.

• Do not connect this LED product directly to mains

voltages.

• This is a 24 V DC product and should always be

connected to a SELV (Safety Extra Low Voltage)

driver. Ensure proper routing of the cable to avoid

cable damage.

• Do not load the power driver beyond 90% of its

rated maximum power.

• Before installation, maintenance or cleaning, always

first switch off or disconnect the power and follow

the appropriate safety procedures.

• Do not apply force on the electrical components

when applying the LEDFlex S.

• These modules are designed with ESD protection

but please take into account the max level indicated

in the datasheet.

• Do not make sharp bends with electrical wires.

• Avoid contact between cables and sharp edges.

• Due to the variety of designs and brands in which

the Philips LED products can be installed, you may

need to use customized mounting accessories to fit

the specific design you are using.

• The fixing/cooling surface must be cleaned before

installing the LEDFlex S modules to remove all dirt,

dust and grease. Please refer to the instructions of

3M™ for best tape fixation (tape type: 5915 of 5952

family).

• Do not mount on Plasticized Vinyl, EVA,

Polyethylene, Polypropylene, PVF, Silicone, and

PTFE. For an indication of materials that are suitable

for mounting refer to the extensive information from

3M™ (tape type: 5915 of 5952 family).

• None of the components of the LEDFlex S

(substrate, LED, electronic components etc.) may be

exposed to tensile or compressive stresses. Use a

strain relief to prevent shear- and peel forces on the

LED module though the connector and/or wiring.

• Connectors can only be used with our Philips

Fortimo LEDFlex S family.

• These connectors are single use.

• Disclaimer: Philips has chosen the the best suitable

tape in the market at the time of product release.

Philips is not liable for loosening of the tape over

time and/or its consequences. The Datasheet of the

3M™ VHB™ Tape 5915 can be found here: https://

www.3m.com/3M/en_US/p/d/b40072037

• If you require further support, please contact your

local Philips sales organization.

System disposal

We recommend that the Fortimo LEDFlex S module

and its components are disposed of in an appropriate

way at the end of their (economic) lifetime. The

modules are in effect normal pieces of electronic

equipment containing components that are currently

not considered to be harmful to the environment. We

therefore recommend that these parts are disposed of

as normal electronic waste, in accordance with local

regulations.

Thermal design

Test Requirements

Measurements shall not be taken until the luminaire has

stabilized thermally, i.e. temperatures are changing at a

rate less than 1 °C per hour (see also the relevant

clauses in IEC 60598-1). For ANSI/UL 8750 the test is to

continue until constant temperatures are obtained. A

temperature is

considered constant if:

a) The test has been running for at least 3 hours, and

b) Three successive readings, taken at 15-minute

intervals, are within 1°C (1.8°F) of one another and are

still not rising.

Module T ambient

The LEDFlex S is a self-cooling product when

used between an ambient temperature of -35 to 50

degrees Celsius, and the light beam of the LEDFlex S is

not covered.

Module Tcase point location

The tc point is located on the accessible silicone surface

of the LEDFlex S module. The thermocouple can be

attached with a high temperature glue or Kapton tape.

Indication of Tc measuring point

Driver Tcase point location

The Tcase point on the driver is indicated by a point or

an asterisk with the Tc caption. Please refer to the driver

datasheet for the exact location. For the thermal

measurements a thermocouple can be attached with a

high temperature glue or Kapton tape.

Introduction

Attention needs to be paid to thermal design-in for

LED-modules and drivers to ensure optimum

performance and life time of the luminaire. The critical

thermal management items for the LED module are set

out in this chapter in order to facilitate the design-in. If

these thermal items are taken into account, this will

help to ensure optimum performance and lifetime of

the LED system.

Relevant definitions are explained along with guidance

on how and where to measure the temperatures.

Key Definitions:

Module temperature: This is the temperature measured

at the specified Tcase or Tc point of the module. This

temperature is directly related to the LED junction

temperature, which is the critical parameter for

operation.

Ambient temperature: This is the temperature of the air

surrounding the luminaire in the test environment or

application. The module and driver temperature

increases, by approximation, linearly with the ambient

temperature. This relation can be used to predict

module and driver temperatures at a different ambient

temperature.

Tc nominal: This is the module temperature at which

the performance is specified.

Tc life: This is the module or driver temperature (equal

or higher than Tc nominal) at which the lifetime of the

module (e.g. lumen maintenance of LxxByy) is

specified.

Tc max: This is the maximum module or driver

temperature

(equal or higher than Tc life) to stay within safety limits.

This temperature must not be exceeded, even in case

of fan failure. The specified Tc nominal, Tc life, and Tc

max are listed in the relevant datasheets that can be

found on our website

philips.com/oem

Thermal design

Cooling

The LEDFlex S is a self-cooling product when

used between an ambient temperature of -35 to 50

degrees Celsius, and the light beam of the LEDFlex S is

not covered. Below you find an indicative table of self

cooling LEDFlex S products when mounted as can be

seen in picture 3. The self cooling values are an

indication only and should alway be verified by a T case

measurement. The self cooling indication is given for a

setup indicated in the below picture (picture 3). Where

the optical efficiency of the cover is 85%.

To warrant the lifetime of the LEDFlex module, two

parameters are key:

1. Ambient operating temperature. The ambient

operating temperature is given in the self cooling

table

2.Tc life: The temperature measured at the Tcase point

located on the accessible silicone surface on the

LEDFlex module. Please refer to the datasheet for the

exact Tc life value.

Drivers

Need to be IP67 rated or build in a IP67 rated driver

compartment. The connection between the driver and

LEDFlex S should be IP67 rated. If placed in the

luminaire drivers are preferably placed as far away as

possible from the modules to prevent heating

interaction. If placed in a separate driver compartment

they are preferably mounted on the inner surface of the

compartment. Do not place the driver on a heat sink that

is used for cooling the modules. If so, it will be heated by

the thermal losses of the LED –modules.

To warrant the lifetime of the driver, two parameters

are key:

1. Ambient operating temperature. The ambient

operating temperature is given in the product

datasheet.

2. Tc life: The temperature measured at the Tcase

point of the driver is located on the top

side. Please refer to the datasheet for the exact Driver

Tcase point location and Tc life value.
