Almost every light application can be served by different color temperatures, including 27 K, 3 K, 4 K, 5 K and 65 K. The color rendering index of all PrevaLED Linear G4 LED module types is > 8. Additionally, a high light quality with a CRI of > 9 is achieved by PrevaLED Linear G4 LED modules with a luminous fl ux of 11 lm, 2 lm, 22 lm or 4 lm. The LED module nomenclature is explained below for the example of an LED module with the following characteristics: CCT = 4 K, CRI > 8, nominal luminous flux = 11 lm, length = 28 mm, width = 2 mm.

9 PrevaLED Linear G4 Introduction 1.6 Luminous flux as a function of forward current The luminous flux of the LED modules depends on the applied forward current. It is possible, however, to vary between the nominal and absolute maximum current values for each module type and also below the nominal current, e.g. to exactly set a requested value for the luminous flux. The diagrams below show the luminous flux at nominal conditions (t p = 55 C) for different currents. 2-mm module, CRI > 8, 55 lm 2-mm module, CRI > 8, 11 lm Luminous fl ux [lm] Luminous fl ux [lm] Operating current I f [ma] Operating current I f [ma] 2-mm module, CRI > 8, 2 lm 2-mm module, CRI > 8, 22 lm Luminous fl ux [lm] Luminous fl ux [lm] Operating current I f [ma] Operating current I f [ma] 2-mm module, CRI > 8, 4 lm Luminous fl ux [lm] By choosing the requested luminous flux on the y-axis of the diagram, you can derive the needed forward current that has to be applied to the LED module on the x-axis. Needless to say, this also works the other way around: For a set current, you can read the corresponding luminous flux on the y-axis Operating current I f [ma] 9

12 PrevaLED Linear G4 Introduction 1.7 Luminous flux and efficiency as a function of t c point temperature All tables and diagrams shown up to now were measured or calculated for a t c point temperature of 55 C, the nominal temperature condition of the PrevaLED Linear G4 LED modules. It is of course realistic and likely that the t c point temperature in a given luminaire differs from the nominal conditions and that this has an impact on the luminous flux and efficiency. If the t c point temperature on the LED module is lower than the nominal temperature of 55 C, the relative luminous flux and relative efficiency are increased. If the t c point temperature on the LED module is higher than the nominal temperature of 55 C, the relative luminous fl ux and relative effi ciency are decreased. The diagram below shows the correlation between the t c point temperature and relative luminous flux/efficiency. Since it shows only relative values, the diagram gives an approximation that can be used for all the different module types (e.g. different color temperatures, different module lengths).* Luminous flux and efficiency as functions of the t c point temperature Relative value [%] Luminous fl ux Effi ciency t c point temperature [ C] * Of course, all tolerances given in the datasheet of the PrevaLED Linear G4 LED modules are still valid. 12

16 PrevaLED Linear G4 Electrical considerations 3 Electrical considerations 3.1 Wiring information The connector used on the the PrevaLED Linear G4 LED modules (pictured above) can handle solid wires and finestranded wires with cross-sections from.2 to.75 mm 2 (AWG 24 18). The use of solid wires is recommended. 3.2 Disconnecting the wire from the connector The connector on the PrevaLED Linear G4 LED module has an easy and simple poke-in and release mechanism. Solid wires can simply be plugged into the connector. If fine stranded wires are used, it is recommended to use the release button on top of the module also for easier insertion. The wires/cables can be removed by pressing the release button on top of the connector and pulling the wires/cables out. The pictures below show how to disconnect a wire from the connector. Trim length The stripped length is recommended to be 8 to 9 mm. Please insert wires in orientation into the PCB. All PrevaLED Linear G4 LED modules, both 2-mm and 33-mm types, are equipped with a populated isolated connector. Moreover, we have now equipped selected LED modules with a connector on the back (see following pictures). This makes wiring even easier and quicker, and the wires are not visible on the top. 3.3 Electrostatic discharge (ESD) PrevaLED Linear G4 LED modules fulfill the requirement of the immunity standard IEC/EN Please note that an electrostatic discharge of more than 2 kv HBM can cause damage, ranging from performance degradation to complete device failure. OSRAM recommends to handle and store all PrevaLED Linear G4 LED modules using appropriate ESD protection methods. PrevaLED Linear G4 2-mm types are designed with a cut-out area in front of the connector (see following picture). This allows you to insert the wires into the connector from the back, avoiding unwanted shadowing by the wires. 16

17 PrevaLED Linear G4 Electrical considerations 3.4 Forward voltage as a function of forward current* The diagrams below show the relative dependence of the forward voltage (V f ) on the forward current (I f ) at different temperatures (from 25 C to 75 C) for the different PrevaLED Linear G4 LED modules. They show only the area that is of interest for lighting applications, which is in first approximation linear. The different colors show different t p temperatures, the numbers below the diagram represent the scaling for different LED module types (the 55-lm and 65-lm LED modules as well as the 11-lm and 13-lm LED modules use the same scale). CRI > 8 Forward voltage V f [V] 25 C 45 C 55 C 65 C 75 C Forward voltage V f [V] 25 C 45 C 55 C 65 C 75 C /65 lm 11/13 lm 22 lm Forward current I f [ma] 2 lm 4 lm Forward current I f [ma] Forward voltage V f [V] 25 C 45 C 55 C 65 C 75 C Forward voltage V f [V] 25 C 45 C 55 C 65 C 75 C lm Forward current I f [ma] 55 lm Forward current I f [ma] * Of course, all tolerances given in the datasheet of the PrevaLED Linear G4 LED modules are still valid. 17

19 PrevaLED Linear G4 LED systems: PrevaLED Linear G4 and OPTOTRONIC LED drivers 4 LED systems: PrevaLED Linear G4 and OPTOTRONIC LED drivers 4.1 LED module/driver combinations PrevaLED Linear G4 LED modules are designed to be used together with OSRAM OPTOTRONIC LED drivers both in the SELV (V f < 54 V) and non-selv (V f > 54 V) range. A single LED module is within the SELV range. By connecting more than one module in series, the voltage reaches the range of the OPTOTRONIC non-selv LED drivers. Series and parallel connection PrevaLED Linear G4 LED modules can be connected either in parallel or in series, as shown in the pictures below. PrevaLED Linear G4 LED modules connected in parallel to an LED driver If LED modules are connected in parallel, the + of one LED module is connected to the + of the following LED module and the - of one LED module is connected to the - of the following LED module. The last LED module in the chain is connected to the LED driver (here again, the + of the LED module is connected with the + of the LED driver and the - of the LED module with the - of the LED driver. A schematic of four LED modules connected in parallel to an LED driver is shown below, together with a picture of two modules connected in parallel. PrevaLED Linear G4 LED modules connected in parallel to an OPTOTRONIC LED driver Example: Parallel connection of two PrevaLED Linear G4 LED modules PrevaLED Linear G4 LED modules connected in series to an LED driver LED modules can also be connected in series to LED drivers. A schematic of four modules connected in series is shown below. PrevaLED Linear G4 LED modules connected in series to an OPTOTRONIC LED driver 19

20 PrevaLED Linear G4 LED systems: PrevaLED Linear G4 and OPTOTRONIC LED drivers Example: Series connection of two PrevaLED Linear G4 LED modules PrevaLED Linear G4 LED modules connected in series to an LED driver with one rotated module If every second module in the chain connected in series is rotated by 18, the wiring can be done with one straight wire (in this case, no S shape is needed). This can reduce the wiring effort and simplify module installation. Example: Simplified series connection of two PrevaLED Linear G4 LED modules Electrically, parallel and/or series connections of PrevaLED Linear G4 LED modules have the following impacts on the electrical parameters: When connecting two modules in parallel: V f (two modules) = V f (single module) I f (two modules) = 2 x I f (single module) When connecting two modules in series: V f (two modules) = 2 x V f (single module) I f (two modules) = I f (single module) When connecting N modules in parallel: V f (N modules) = V f (single module) I f (N modules) = N x I f (single module) When connecting N modules in series: V f (N modules) = N x V f (single module) I f (N modules ) = I f (single module) OSRAM OPTOTRONIC SELV LED drivers cover a voltage range up to 54 V. This means that for using SELV LED drivers, a parallel-only wiring of the PrevaLED Linear G4 LED modules to the LED driver is necessary. When using LED drivers from the non-selv/non-isolated portfolio (voltage range from 54 V to 15 V 24 V), it is possible to connect the LED modules in series to the LED driver or to use a combination of parallel and series connection. Definition of the XsYp notation: The tables in the datasheets and in section 4.3 (see here) use the XsYp notation with X representing the number of LED modules that are connected in series and Y representing the number of LED modules connected in parallel. 2

21 PrevaLED Linear G4 LED systems: PrevaLED Linear G4 and OPTOTRONIC LED drivers XsYp notation Yp Xs The tables in the datasheets do not only provide information about how many LED modules can be connected to an OPTOTRONIC constant-current LED driver, but they also show the exact wiring schematics. 4.2 Installation examples Connection scenarios of the PrevaLED Linear G4 LED modules as shown below are based on the most common applications. Many other scenarios, e.g. three LED modules (1s3p or 3s1p) are possible. If you have any further questions about the installation of PrevaLED Linear G4 LED modules, please consult your local OSRAM sales representative. Please note: The following calculations were done using nominal conditions (if not mentioned otherwise) for forward current (I f ), luminous flux, etc. These settings can, of course, be adjusted. This can change the LED module/led driver combinations listed in the examples. Example 1: 1s5p Five LED modules connected in parallel to an OPTOTRONIC SELV LED driver Application example: 5-ft damp-proof luminaire Example components: PrevaLED Linear G4: PL-LIN-Z X2, five modules Five LED modules connected in parallel to an OPTOTRONIC SELV LED driver Electrical parameters of one PL-LIN-Z X2: Forward current (I f ) = 175 ma, forward voltage (V f ) = 33.2 V Five LED modules connected in parallel: Forward voltage: V f (five modules) = V f (one module) = 33.2 V Forward current: I f (five modules) = 5 x I f (one module) = 875 ma From the OSRAM LED driver portfolio, there are some drivers that would fit, e.g.: OT FIT 55/22-24/1A CS L G2 (as a linear on/off driver) OTi DALI 5/22-24/1A4 LT2 L (as a linear dimmable DALI driver) 21

22 PrevaLED Linear G4 LED systems: PrevaLED Linear G4 and OPTOTRONIC LED drivers Please note: If the LED modules are connected in parallel to the LED driver, it is possible to combine 28-mm LED modules and 56-mm LED modules with the same LED pitch (i.e. 65-lm LED modules with 13-lm LED modules and 11-lm LED modules with 22-lm LED modules). The main benefit is that less components have to be connected and assembled. (There can also be a price advantage.) The electrical parameters remain unchanged. For our example, this means: Electrical parameters of one PL-LIN-Z X2: I f = 175 ma, U f = 33.2 V, of one PL-LIN-Z X2: I f = 35 ma, U f = 33.2 V Parallel connection of 2 x PL-LIN-Z X2 + 1 x PL-LIN-Z X2: U f (2 x PL-LIN-Z X2 + 1 x PL-LIN-Z X2) = U f (one module) = 33.2 V (same as before) I f (2 x PL-LIN-Z X2 + 1 x PL-LIN-Z X2) = 2 x I f (PL-LIN-Z X2) + 1 x I f (PL-LIN-Z X2) = 2 x 35 ma + 1 x 175 ma = 875 ma (same as before) Example 2: 4s1p Four LED modules connected in series to an OPTOTRONIC non-selv LED driver Application example: 4-ft damp-proof luminaire Example components: PrevaLED Linear G4: PL-LIN-Z X2, four modules Four LED modules connected in series to an OPTOTRONIC non-selv LED driver Electrical parameters of one PL-LIN-Z X2: I f = 175 ma, U f = 33.2 V Four LED modules connected in series: U f (four modules) = 4 x U f (one module) = V I f (four modules) = I f (one module) = 175 ma From the OSRAM LED driver portfolio, there are some drivers that would fit, e.g.: OT FIT 35/22-24/35 D LT2 L (as a linear on/off driver) OTi DALI 35/22-24/4 D LT2 L (as a linear dimmable DALI driver) 22

28 PrevaLED Linear G4 Thermal considerations 5 Thermal considerations At nominal operating conditions, with the PrevaLED Linear G4 mounted onto or into a luminaire housing with heat exchange to the environment, no special additional heat sink is needed to avoid exceeding t c max = 75 C. To avoid overheating, it is nevertheless strongly recommended to check the LED module temperature in any newly designed luminaires. It should also be mentioned here that lower t c point temperatures on the LED module increase the module s efficiency. Therefore, providing efficient cooling for the PrevaLED Linear G4 LED modules increases the system efficiency of the luminaire/application. 5.1 Introduction and definitions For any LED module, including the PrevaLED Linear G4 family, different temperatures (t p, t c, t c max etc.) are mentioned in the datasheet. They are sometimes confused, therefore a short overview should be given at the beginning of this chapter: All the temperatures mentioned above are measured at the same point on the LED module, which is (mostly for historical reasons) called the t c point of the LED module. Its position on the PrevaLED Linear G4 LED modules is shown below. 5.2 t c location and measurement Proper thermal design of an LED luminaire is critical for achieving best performance and ensuring long lifetime of all components. To achieve a lifetime of 5 hours (L8B1), the sufficient heat exchange and thermal conduction between the light engine and the luminaire housing has to be verified by measuring the temperature at the t c point. The maximum temperature reached at the t c point must not exceed 75 C. This reference point for PrevaLED Linear G4 is shown in the image below for the 11-lm/28-mm LED module type (for the other LED module types, the position is similar). t p is the performance temperature of the module. That means that all the tables, diagrams and numbers in the datasheet (and in this technical application guide) refer to the performance temperature t p (if not mentioned otherwise). t c is the critical module temperature of the LED module. Up to this temperature, one special feature can be guaranteed (e.g. the efficiency of the LED module at nominal current is higher than 15 lm/w up to a temperature of t c = 55 C). t c max is the absolute maximum temperature up to which the operation of the LED module is recommended. Position of the t c measurement point on PrevaLED Linear G4 LED modules t c measurement point The easiest way to measure the temperature at the t c point is by using a thermocouple. It is recommended to use a thermocouple that can be glued onto the LED module. Make sure that the thermocouple is fixed with direct contact to the t c point. 28

The voltage increases with decreasing temperature. Therefore, when looking for a suitable LED driver, the forward voltage of the cold system at the coldest specified temperature has to be considered.

30 PrevaLED Linear G4 Lifetime and lumen maintenance 6 Lifetime and lumen maintenance For the definition of the lifetime of an LED module, see IEC/PAS 62717, where the following types are defined: The luminous flux of an LED module decreases over its lifespan. This decrease is specified by the L value. LXX means that XX % of the initial light output is emitted by the LED module (e.g. L7 = 7 %). The L value is always connected to an operating time and defines the lifetime of an LED module. Please be aware that the L value is a statistical value. Therefore, the decrease in light output can and will vary for different modules. Average lifetime vs. t c at CRI > 8 Lifetime [h] L8B1 The B value specifies how many LED modules are below a stated limit, e.g. B5 means that 5 % of the LED modules are below a given L value. The C value gives the number of fatal failures, meaning the number of LED modules that are destroyed and do not emit any light at all (e.g. C1 after 5 hours means that after 5 hours in operation, 1 % of the LED modules do not emit any light). The F value is the combination of the B and C value, meaning that both fatal failures and degradation are considered. Some examples: LC1 is the lifetime where the light output is % for 1 % of the LED modules. L7B5 is the lifetime where the light output is 7 % for 5 % of the LED modules. The B value includes only gradual reduction of lumen output over time (not the abrupt flux degradation). L7F5 is the lifetime where the light output is 7 % for 5 % of the LED modules. The F value includes reduction of lumen output over time including abrupt degradation (flux = ) t c temperature [ C] Average lifetime vs. t c at CRI > 9 Lifetime [h] L8B t c temperature [ C] PrevaLED Linear G4 LED CRI > 8 modules have a lifetime of 5 hours (L8B1) at a t c point temperature of 55 C. This means that after 5 hours, a minimum of 9 % of the utilized LED modules will maintain at least 8 % of the initial luminous fl ux. PrevaLED Linear G4 LED CRI > 9 modules have a lifetime of 5 hours (L8B5) at a t c point temperature of 55 C. This means that after 5 hours, a minimum of 5 % of the utilized LED modules will maintain at least 8 % of the initial luminous fl ux. Please note: A higher t c temperature leads to a shorter lifetime of the LED module. Moreover, the failure rate will also increase. 3

The LED module has to be protected by a suitable IP rating of the luminaire housing. Please consider the luminaire standard IEC 6598 as well as the different requirements. 7.4 Mounting instructions Please apply force only to the dedicated mounting positions. Strong mechanical stress can lead to irreversible damage of the LED module. To fi x the module to the fi xture, you can use M4 screws according to DIN 7984 or DIN EN ISO. The maximum allowed screw head diameter without using an isolating washer between the screw and the mounting hole is 7.5 mm. With larger screw heads, the minimum distance between the screw and other conductive parts on the PrevaLED Linear G4 LED module can be below the limit for creepage distances. The maximum torque that should be applied on the screws depends on factors such as the screw type and the luminaire material. It is also infl uenced by the usage of washers. In most cases, a torque between.5 Nm and 1 Nm is enough to fi x the LED module in the luminaire housing and will not damage the module. Possible screws Cylinder head, torx drive M4 screw (ISO 4762) Diameter 4. mm Head diameter 7. mm Head height 4. mm Flat head, button head M4 screw (ISO 738) Torx drive, hex drive Diameter 4. mm Head diameter 7.5 mm Head height 2.1 mm It is also possible to use clips instead of screws, e.g. the push-to-fi x (P2F) connectors from BJB: To achieve optimal fi xation of the LED module and also optimal thermal management, it is recommended to use all mounting holes in the PrevaLED Linear G4 LED modules. Nevertheless, it is possible to reduce the number of screws, but in that case thermal behavior and mechanical strength has to be verifi ed. In any case, it is strongly recommended to perform mechanical and thermal testing of the LED modules in the luminaire. 37
