How to Use LED Linear systems in outdoor luminairesNeither the LED modules nor the indoor Linear LED driverhave an IP classification IP20. Furthermore for outdoorluminaires, compliance to a higher mains surge standard isrequired than the indoor standard LED module is testedagainst. Not complying with the outdoor standard will leadto damaged LEDs. If deciding to use these products in aluminaire for outdoor applications the OEM will beresponsible for ensuring proper IP protection, adequatemains surge protection and approbation of the luminaire.Please consult Philips if you wish to deviate from thedesign rules described in this guide (see last page forcontact details).Commercial naming of the Philips LED Linear modulesThe names of Philips LED Linear are defined as shown inunderneath example.

T8650 and 1000 lm/ftT5 HE 700 lm/ftT5 HO 1000 and 1300 lm/ftWhy replacing fluorescent by smart LED building blocksInstead of replacing hundreds of unique ballastfluorescent tube combinations, as the fluorescent market isused to for decades Philips has chosen in the LEDapproach to use smart building blocks.These are the Philips LED Linear modules in combinationwith the Philips Window drivers – strong in flexibility.LED Linear 650, 1100, 2000 lm/ftRelation between fluorescent lumen and LED Linear lumen.Characteristics of these building blocks are Lengths mimic fluorescent lamps(0.5 ft, 1 ft and 2ft blocks). Driver dimensions mimic conventional ballasts. Various LED lay-outs enabling glare and beam control. Lumen-ranges cover fluorescent lumen packages.By analyzing the mainstream fluorescent lumen packages(amount of lumen per unit length [lm/ft]) three main valuescan be noted as can be seen in the table on the left; 650,1100 and 2000 lm/ft. For reference please see table inAppendix A.However, with the ability to select and set the drive currenton the LED driver you are able to select your light output(lumen) different than the default. This degree of freedomand flexibility we call tuning and will be explained in a latersection.How to Convert to your preferred LED Linear solutionThis section is to help you find your preferred LED Linearsystem solution, starting from your familiar fluorescentsystem.

Electrical design-inIn this section you will find all of the electrical design-ininformation needed to design your configuration based onthe Philips LED Linear system.Short introduction to operating LEDsThe LED is a semi-conductor device which, when anelectrical current (Amperes) flows through it, emits light.The current cannot flow without a Voltage over the LED,called the forward Voltage (Vf). Forward Voltage (Vf) is theforce to open the gate, allowing the current to flow throughthe LED. Drive current (Idrive) is transformed into light bythe LED. The amount of light (luminous flux [lm]) isproportional to the amount of current.Reasons why to set your drive currentWith LED as a light source more flexibility in your luminairedesign is enabled with respect to conventional light likefluorescent. We would like to explain to you why youwould want to determine and set your drive current troughthe LEDs.Each LED module needs an electrical current to be able toemit light. In fact, the amount of light – flux [lm] – isproportional to the electrical current flowing through theLEDs.1. For starters, any LED module needs it specific drivecurrent to emit a given amount of light (lm).2. With a generation update, lumen per Watt (lm/W) willimprove, hence the required current to achieve itsluminous flux (lm) will decrease resulting in a lowerrequired drive current.3. Opposite to lamps, LED modules allow composition oflight lines into a system, comprising from one up tomany LED modules in that system. Differentcombinations require different currents and Voltages.4. Changing the drive current through to system (hence it’sLEDs) will enable you to tune to a desired light outputother than the nominal flux specified at the nominaldrive current.14Design-in Guide - Philips LED Linear systems LV & HV - May 2019

Philips Indoor Linear LED driversFor the drivers, the same documentation philosophy holdsas for the LED modules, meaning that also threedocuments make up the full information set of the drivers.DatasheetFor detailed info, please refer to the Commercial Leaflet ofthe Indoor LED drivers, the Design-In Guide for XitaniumIndoor Linear LED drivers and the associated driver’sdatasheet on t voltage [V]Commercial leafletDesign-in Guide2505200131504100502000.10.20.30.40.5Output current [A]Example of a Driver Operating Window1.2.3.4.5.Required set point for the LED solution.Current can be set to needs within range.Driver adapts to required voltage within range.Driver minimum power limit to guard driverperformance.Driver maximum power limit to guard driverperformance.Note: Power (W) Voltage (V) x Current (A).Note: by means of dimming it is possible to go belowthe minimum value of the specified output current.Xitanium driver operating windowLED technology is rapidly evolving. Using more efficientLEDs in a next generation means the same light output canbe achieved with less power, hence lower drive currents. Atthe same time, LEDs can be driven at different currentslevels based on the application requirement. Typically, LEDdrivers are available in discrete current levels e.g. 350 mA,500 mA or 700 mA. It is often necessary to replacea driver when more efficient LEDs or different LEDmodules become available.One of the key features of the Xitanium LED drivers is theadjustable output current (AOC), offering flexibility,differentiation for the OEM and future-proof luminairedesign. The Xitanium drivers can operate in a so called“operating window”. This power window is defined by themaximum and minimum voltage (V), current (A) and power(W) that the driver can handle. An example of an operatingwindow is shown on the left. The area indicates thepossible current /voltage combinations. The current youselect will depend on the type and manufacturer of theLEDs, the specific LED configuration of the PCB design andthe desired output (lm) per LED.The voltage required is the sum of the LEDs used (total Vfstring). Within the driver window’s range the driver willadapt to the Voltage requirement. Both the operatingwindow and default current setting of every driver can befound in the datasheets in the download section onwww.philips.com/technology.Design-in Guide - Philips LED Linear systems LV & HV - May 201915

Single channel driverCurrently all the Philips Indoor Linear LED drivers are singlechannel drivers. This means for drivers with a double “ ”and “-“ output, that these outputs are in parallel inside thedriver allowing easy connection of parallel LED chains.System configurations with LED LinearAs the default current of the drivers does not necessarilymatch your system drive current requirement, please besure to set and check the current on the driver, e.g. bymeans of current measurement. When configuring thesystem with the Philips driver and Philips LED modules, theselected driver operating point needs to be within thedriver operating window. In case of questions, contact yourlocal Philips representative or the Philips Design-In Team.Setting the driver output currentCertaDrive LED drivers have a fixed output current, nonselectable. Xitanium drivers do have an operating window,allowing to select the output LED drive current. The outputcurrent of these drivers can be set in two ways.1. By connecting a specific resistor value to the driver’sRset input.2. TD driver versions can be programmed via theMultiOne interface in order to set the desired current(www.philips.com/multione).For more information on programming these driversplease check the Design-In Guide of Xitanium IndoorLinear LED drivers in the download section onwww.philips.com/technology.How to determine what value the output current should beset at will be explained in the upcoming sections.Insulation safety indicated by working voltageThe working voltage is the highest voltage that may occuracross any insulation of the module without compromisingthe safety of the module. Any driver with an open load/circuit voltage below the working voltage of the modulecan be safely used in combination with the module.16Design-in Guide - Philips LED Linear systems LV & HV - May 2019

* N ote: when connecting Philips LED modules to thedriver, the type of LED module (LV or HV) determines thisrequirement. Hybrid LED modules (HV/LV in the name)can be used on both type of drivers, indicated inCommercial Leaflet, to be found in the downloadsection of www.philips.com/technology.** Note: Philips LED Linear standard system configurations,driven at nominal current, are stated in the CommercialLeaflet, to be found in the download section ofwww.philips.com/technology. ote: for a HV scenario that allows a 2 chain parallelNsolution, you are likely to find with steps described alower rated driver power (e.g. 75 W for 1 chain versus36 W for 2 chain solution).Power [W] Voltage [V] x Current [A]How to Select an appropriate driverDepending on your requirements several drivers can befound as a solution for you. The following steps can helpselecting the preferred driver.For a full overview of available driver models, please referto the commercial leaflet Xitanium indoor linear LEDdrivers, to be found in the download section ofwww.philips.com/technology, as are the datasheetsassociated with the drivers you intend to use.1. Determine your required drive current (Idrive) andvoltage (Vf).2. Calculate required power via:Pdrive (W) Vf (V) x Idrive (A).3. Determine which type* of driver you do need; Isolated(LV system, Class II/SELV) or Non-isolated (HV system,Class I).Collect the associated datasheets from the website.4. Does required current fit current range of driver?- Idriver minimum Idrive Idriver maximum?5. Does required voltage fit voltage range of driver?- Vdriver minimum Vf Vdriver maximum?6. Does required power fit power range of driver?- Pdriver minimum Pdrive Pdriver maximum?7.

INOUTINOUT---LV LED moduleLV LED moduleHow to Configure an LV systemLV systems typically use LV LED modules or Hybrid LEDmodules suitable for LV usage, connected to an isolateddriver. LV products make a parallel system; adding a LEDmodule requires a higher current.1. Determine the operating current for the desired flux perLED module, using the datasheet. Make sure theoperating current does not exceed the specified valuefor lifetime.2. Drive current from the driver is the sum of the currentrequired per LED module.3. Check whether the resulting total current is within thedriver’s current range. If the current is too low, you candecide to select a driver with a lower output power. Ifthe current is too high for the selected driver, a driverwith a higher output power may provide a solution.4. Connecting too many LV LED modules in a single chainmay lead to flux imbalance. Check the advisedmaximum number of LED modules per chain in theassociated LED module datasheet. If the number of LEDmodules in your system exceeds the specified maximumvalue it is advised to create a second chain.-Schematic representation of the wiring of 2 connected LV LEDmodules in an LV system, not needing a Return-End cableIdrive Inom [A] x # modulesRequired drive current equals nominal current ofone LED module times number of LED modules.Vdrive Vf [V]Required drive voltage equals forward voltage ofone LED module.Note: That the number of LED modules per chain does nothave to be the same for all chains, since all LED modulesare electrically connected in parallel.Note: For your convenience isolated drivers (LV system)comprise a duplicate – parallel
