4 Introduction to the Fortimo LED Twistable Downlight Module (TDLM) Gen 2 Applications Philips Fortimo LED Twistable Downlight Module Gen 2 has been primarily designed for indoor applications but may, in certain circumstances, be used in certain damp location (provided all applicable laws and regulations are followed, including UL 1598). The Philips Fortimo LED TDLM, as the name suggests, is designed and intended for general downlight in accordance with North American luminaire standard, UL TDLM 1100 lm Module 1 Examples of applications include: Hospitality (hotels representative areas such as receptions, boardrooms, restaurants, etc.) Cruise ships (corridors, cabins) Public buildings (schools, cinemas, theaters, exhibition halls) Office (Corridors, reception/lobbies, waiting area) Urban outdoor lighting (ground lighting, post-top lanterns) Retail (corridors, general waiting area, dressing room area, mall facades) Product description To operate a system the following products are needed: A Philips Fortimo LED TDLM Module Gen 2 A heatsink (sold separately) A reflector (depending on the application) (sold separately) Lampholder (sold separately) TDLM 2000 lm Module Classification The Philips Fortimo LED Twistable Downlight Module Gen 2 can be used in: Non Class 2 system (luminaire heat sink must be grounded) Neither the Philips Fortimo LED Twistable Downlight Module Gen 2 nor its lampholder can be used for wet location applications. So if an OEM decides to use the system in a luminaire for outdoor applications, the OEM is solely responsible for relevant approbation design as well as compliance with any and all laws, standards and regulations. About the module The protective housing allows easy handling during transport and installation. It also protects the LEDs from direct access/damage once mounted, and ensures the appropriate safety distance between the LEDs and any metal objects (for example a reflector). The connector allows quick and easy installation and replacement of the module. 4 Design In Guide Philips Fortimo LED Twistable Downlight Module Gen 2

5 Generation 2 Philips is continuously improving its Fortimo products. The second generation of the Fortimo LED Twistable Downlight Modules has been developed to enable LED adoption and upgrades very easily. The range aimed at energy efficiency has a very good Total Cost of Ownership and is easy to install. There is no training and tooling required resulting in low maintenance thus reduced running costs over the lifetime of the luminaire. This range changed from remote phosphor to white LEDs to help deliver better efficiency. The quality of LEDs does not require the phosphor plate anymore. The modules will continue to ensure the same high quality. Finally, the 1100 lumen module is Zhaga 1 certified, the full range of TDLMs will be Zhaga certified from Q onwards.

6 LEDs powering Fortimo LED Twistable Downlight Module Gen 2 The development of Light Emitting Diodes (LEDs) is progressing at such a pace that they are rapidly gaining a majority of use for lighting applications. To most people, the term LED still only means the small indicator lights that show whether the TV set is switched on. These tiny light sources barely emit enough light to make themselves visible. In the Fortimo LED Twistable Downlight Module Gen 2 system, multi-die white LEDs are used. This package enables high efficiency, high lumens, and minimum CRI of What is LED? LEDs are solid-state devices, built up from crystalline layers of semiconductor material. The light generation process makes use of the special electronic properties of crystalline semiconductors in a process called injection luminescence. In brief, this means the injection of charged particles by an electric field from one semiconductor layer into another, where they are able to relax to a lower- energy state by emitting visible light. LEDs produce narrow light spectra. The bandwidth remains limited to a few tens of nanometers, and is therefore perceived by the human eye as a single, deeply saturated color. LEDs are now available in all wavelengths of the visible spectrum; yellow is the only region in which no high-power LED is currently available. White light can be produced by combining LEDs of different colors (for instance red, green and blue), or by applying phosphor coatings on blue or ultraviolet LEDs. Like many other lamps, LEDs cannot be connected directly to the mains. The LEDs have to be operated at a stabilized low voltage, which is provided by driver electronics. However, LEDs do not need ignition and can be switched on/off within milliseconds. LEDs do not generate nearly as much heat as many other lamps, but that does not mean that thermal design is not important. LEDs do produce heat when they operate, and are themselves relatively sensitive to temperature. Thermal considerations are therefore very important aspects of luminaire design that incorporates LEDs. 6 Design In Guide Philips Fortimo LED Twistable Downlight Module Gen 2

7 LED packaging The bare LED die is still a very sensitive and fragile device that must be handled in a clean room environment. Before bringing them outside, they must be packaged. The light flux of conventional LEDs, for example those used as indicator lights on TV sets, is severely limited by the amount of heat generated. In practice, conventional LED packages are limited to about 0.15 W at most, and emit only a few lumens. The LEDs used in Fortimo LED Twistable Downlight Module Gen 2 are middle power single-die packaged, composed of blue dies with phosphor. Binning The subject of binning should be explained because of its importance in LED system design. As in other semiconductor manufacturing processes, in LED production the number of parameters of the epitaxial process is very large and the process window small (for example, the temperature must be controlled to within 0.5 C (<1 F) across the wafer at temperatures of ~800 C/1470 F).The difficulty of achieving such a high degree of control means that the properties of the LEDs may vary significantly within single production runs and even on the same wafer. To obtain consistency for a given application, binning (= selection in bins) is mandatory. Binning involves characterization of the LEDs by measurement and subsequently categorizing them into several specific bins. To keep the cost per LED down, LED manufacturers must sell the full production distribution. At the same time they cannot guarantee the availability of all bins at all times. There is a trade-off between logistics and cost price on the one hand, and the application requirements on the other. Setting the specification too tightly will increase the cost price and may lead to logistics problems. System design should therefore try to combine LEDs from different bins intelligently to obtain the required system performance at a reasonable price and with reasonable delivery reliability. Mid-power LED The binning of the Mid-power LED was done at 65mA, 25C condition. Bins of color, Vf, and flux are properly mixed to achieve a good color consistency, a tight Vf and flux tolerance. Miniaturization LEDs are typically much smaller than conventional light sources. Lighting designers and specifiers immediately recognized the fact that LEDs allow dramatically different lighting designs that capitalize on these tiny, unobtrusive light sources. This is understandable, but care must also be taken to deal with the heat produced by power LEDs. Proper heat management places limits on miniaturization.

12 Lighting characteristics Light distribution The light distribution of the Fortimo TDLM is near lambertian and can be used for a multitude of applications. The light distribution can best be controlled using a specular/ near-specular reflector. Optical files On the Philips website ( optical files can be downloaded in the following formats: IES, including a file with Ray-sets. Photometric files can be used to check the modules far-field intensity distribution. The initial reflector or luminaire design can be carried out using a lambertian emitter to gain simulation speed. The final design should always be verified using a simulation executed with a rayset for the Fortimo Twistable Downlight Module.

15 Color consistency (SDCM) The target specification of the Philips Fortimo LED Twistable TDLM Module Gen 2 range for colour consistency is within 4 SDCM 2 ellipse inside ANSI quadrangle. SDCM stands for Standard Deviation of Color Matching and the value 4 refers to the size of an ellipse around the black body locus. Note: Philips maintains a tolerance of ± 0,005 on x, y color points measurements. This figure shows color targets for the different color temperatures of the Fortimo LED Twistable Downlight Module Gen 2 Modules. These are specified in the operating conditions (Tc 65 C). In the application a color shift is possible if the Tc temperature is significantly lower than in these targets. Reflector design The reflector design can be done by the OEM or can be supplied by a complementary partner. If the OEM wants to design its own reflector, raysets can be downloaded from the Fortimo website ( If more support is needed, please contact the key account manager or your local Philips sales representative. Different reflector suppliers have designed a reflector that fits the Philips Fortimo LED Twistable Downlight Module Gen 2; Jordan, ACL, Alux Luxar and NATA. These companies can be contacted via their website. Design In Guide Philips Fortimo LED Twistable Downlight Module Gen 2 15

16 Thermal management The critical thermal management points for the module and driver are set out in this chapter in order to facilitate the design-in of Fortimo LED Twistable Downlight Module Gen 2. Keeping these thermal points in mind will help to ensure optimal performance and lifetime of the system. Temperature test point at bottom PCB Operating temperatures Definitions Module temperature: temperature measured on the Tc point of the module Module Ambient Type temperature: temperature outside the 1100 luminaire lm 2000 lm Max Tcase 70 C (all CCTs) 70 C (all CCTs) Typical Tcase 65 C (all CCTs) 65 C (all CCTs) Max Thermal Power at thermal 2700 K 10.6W 19.1W Max Thermal Power at thermal 3000 K 9.7 W 18.5W Max Thermal Power at thermal 3500 K 9.7W 18.4W Tambient 45 C 45 C Test requirements The test results of T case and T ambient case of the Module in open air or in the standard wooden box will give different results. The worst case test is the wooden box with T ambient 45 ºC. Temperature measurements should only be performed when the luminaire is thermally stable, which may take 0.5 to 2 hours depending on the thermal capacity of the luminaire. For all measurements such as temperature, luminous flux and power, a stabilization period of at least half an hour must be allowed before any reliable data can be obtained. Measurements must be performed by means of thermocouples that are firmly glued to the surface (and not, for example, secured with adhesive tape). Maximum Temperature Because LEDs are temperature-sensitive, LED modules require a different approach with respect to the maximum permissible component temperature. This is different than most other types of light sources. Some of the LED modules have a shut down circuit when temperature becomes to high. The Fortimo LED Twistable Downlight Module Gen 2 has no shut down circuit and therefore requires proper thermal design. Critical measurements Tc point For LEDs the junction temperature is the critical factor for operation. Since there is a direct relation between the case temperature and the LED junction temperature it is sufficient to measure the bottom side of the module. The critical point is on the back surface of the LED module. If the case temperature (Tc) at the critical measurement point is too high (exceeding 70 C), the performance of the LEDs will be adversely affected, for example in terms of light output, lifetime or lumen maintenance. 16 Design In Guide Philips Fortimo LED Twistable Downlight Module Gen 2

17 Case temperature To ensure the performance and to enable temperature measurement in a luminaire, a Tcase point has been defined at the back surface on the Fortimo Twistable Downlight Module Gen 2. Module with closed heat sink Where to pay attention? Tcase can be measured on the heat sink, either by making a v-groove in the heat sink (Tcase 1) OR making a drill hole in the heat sink (Tcase 2) (gluing the thermocouple-wire to the heat sink is strongly recommended). The Thermal Interface Material (TIM) stays on the twist and makes thermal contact with the heat sink. Module with open heat sink Where to pay attention? Tcase can be measured on the heat sink, by making a v-groove in the heat sink (Tcase 1) (gluing the thermocouple-wire to the heat sink is strongly recommended). The Thermal Interface Material (TIM) stays on the twist and makes thermal contact with the heat sink. Design In Guide Philips Fortimo LED Twistable Downlight Module Gen 2 17

18 Thermal management Operation under built-in conditions The heat produced by LED module in the luminaire (or similar housing) must be dissipated to the surroundings. If a luminaire is physically insulated by a ceiling, wall or insulation blanket, the heat produced cannot easily be dissipated. This will result in heating of the LED module in the luminaire, which in turn can have an adverse effect on system performance and lifetime. For optimum performance and lifetime it is important that: air can flow freely around the luminaries; and airflow through the luminaire, around the modules, has a positive effect on temperature control and hence on performance and lifetime. Thermal interface In the Fortimo LED the thermal interface is already attached on the module. Do not remove the thermal interface material. Heatsink design To ensure that housing temperatures do not exceed the specified maximum values, a luminaire can act as an additional heat sink. The applicable heat transport mechanisms are conduction via the heat sink and convection and thermal radiation to the surroundings. The objective of this chapter is not to indicate exactly how to calculate a heat sink, but to give some guidelines on how to improve its performance. Although a heat sink can have many (complex) shapes, the following discussion is based on a disk type of heat sink. The results for square plates, etc., may be similar provided the surface areas are equal. The type of material used has a relatively large influence on the final result. For example, a comparison of the thermal conductivity (k) of copper with that of corrosion- resistant steel (see table left) shows that a substantially smaller heat sink can be made with copper. In practice the best material for heat sinks is (soft) aluminum. The thickness (d) of the heat sink disk is also of major importance. Assuming the use of different heat sinks of the same diameter but made from different materials, the same effect in terms of temperature difference will be achieved if the product of thermal conductivity (k) and disk thickness (d) is constant. This means a similar result is obtained with a disk of 1 mm copper, 2 mm aluminum, 4 mm brass, 8 mm steel or 26 mm corrosion-resistant steel. Increasing the diameter, and thereby also the surface area, of the heat sink disk also leads to an improvement, but the effect is smaller for larger diameters and depends on the thermal conductivity (k) of the material and the thickness (d).thermal radiation can also form a substantial part of the total heat transfer, and is of the same order as for convection. This depends strongly on the emission coefficient of the surface, which lies between 0 and 1. For example, a polished aluminum surface has a very low emission coefficient, while that of a painted surface is very high. For passive cooling, high emission coefficient is preferred. 18 Design In Guide Philips Fortimo LED Twistable Downlight Module Gen 2

19 Thermal Conductivity Material W/mK Copper 400 Aluminium 200 Brass 100 Steel 50 Corrosion-resistant steel 15 Emission Material Surface Emission coefficient Aluminium New/polished Oxidized Anodized 0.8 Steel Painted New/Polished Heavy oxidized Thermal de-rating system The Fortimo LED Twistable Downlight Module Gen 2 has no shutdown circuit and therefore requires proper thermal design. Size of heatsink & Thermal Interface Material (TIM) The module contains a built-in heat spreader. The module must be connected to the heat sink with a thermal interface material (TIM) in between which makes sure of a perfect contact between the module and the heat sink. The module has a thermal power that needs to be taken away. The spreader at the back of the module is the contact area for the external heat sink. The performance (life time and amount of light) of the module depends heavily on the thermal management. Therefore the temperature of the test point (Tc) is important. During the thermal design process, the aim is to keep the Tc temperature at the stated range. Thermal Interface Materials (TIM) are thermally conductive materials, which are applied to increase Thermal contact conductance across jointed solid surfaces, such as between microprocessors and heatsinks, in order to increase thermal transfer efficiency. Without a TIM the heat that is generated by the module cannot be managed effectively by the heat sink. This will result in poor performance or total failure of the module or fixture. Please note that in an assembly scenario where metal screws are not used to fix the heat sink to the module, then a non-isolated thermal interface material (also known as electrically conductive TIMs) must be used to ensure proper grounding. Design In Guide Philips Fortimo LED Twistable Downlight Module Gen 2 19

20 Thermal management Air flow Before starting with any calculation, an important point to consider is the airflow. In general hot air is moving upwards with relatively low speed. The form and position of the heat sink is influencing the airflow. If the fins are perpendicular to the airflow which reduces the efficiency of the heat sink. This situation should be avoided. A better way to position the fins is to have the fins parallel to the airflow direction. Closing the top of the profile will reduce the efficiency of the heat sink as well, and should be avoided during design and installation. Thermal model Standard STATIC thermal situations can be modelled with so-called thermal resistances. These resistances behave like electrical resistors. Below the analogy between electrical and thermal resistors is explained. Where on the left the electrical units are mentioned, on the right the thermal equivalent is set. With a known voltage difference at a certain current it is possible to calculate an electrical resistor with Ohm s law. The same is possible with a thermal resistor. If the temperature difference and the thermal power is known, the thermal resistance can be calculated with thermal Ohm s law. Analogy between electrical and thermal resistance Thermal model 20 Design In Guide Philips Fortimo LED Twistable Downlight Module Gen 2

21 Calculating your heat sink We start with a thermal calculation formula: Formula (f1) the relation between temperature difference, thermal power and thermal resistance. With this formula the needed thermal resistance can be calculated when the thermal power and temperature difference are known. Formulas: Thermal: Δ T = Rth x Pth (f1) Next we gather all available information, as can be found in the datasheet, application details and design choices. Below we calculate the needed thermal resistance of the heat sink, such that in typical situations, the typical temperature of the test point Tc, is below its maximum. Available information Tc-typ = 65ºC Pth- Twistable DLM 2000 lm, 3000 K = 19.1 W Tambient-max in application = 45ºC Below we show an example of how to calculate the needed thermal resistance of the heat sink, such that in worst case situations, the maximum temperature of the test point Tc, is below its maximum. Calculation of total maximum thermal resistance: (f1) ΔT - Tlmb = = 20ºC Rth = ΔT / Pth = 20/19 = 1.05 K/W Now we know the thermal resistance of the needed heat sink. This heat sink dimension is such that at maximum power and maximum ambient temperature claimed by the luminaire makers, the temperature of the test point Tc should be below 70 C. This assures that lifetime, color temperature, and light output will be according to specifications. The heat sink dimension can be smaller if the luminaire maker claims a Tambient-max less than 45ºC. Calculation would be carried out according to a similar methodology. Interested in the heatsink complementary partners: Three of the heatsink partners that have been working with Philips are Nuventix, AVC, and Sunon. All three have made heatsinks specifically for Fortimo LED Twistable Downlight Modules according to the reference heatsink design from Philips. The following are suggestions of products that can be used with certain Philips Fortimo LED Twistable Downlight Modules. References to these products does not constitute their endorsement by Philips. Philips makes no warranties regarding these products and assumes no legal liability or responsibility for loss or damage resulting from the use of the information herein Design In Guide Philips Fortimo LED Twistable Downlight Module Gen 2 21

22 Electrical design Wiring The mains supply cale must be connected to the lampholder. The earth connector needs to be connected to the heatsink/luminaire because the Fortimo LED Twistable Downlight Module Gen 2 is specified as class I. The lampholder is screwed with 3x M3 metal screws to the heatsink. In an assembly scenario where metal screws are not used to fix the heat sink to the module, then a non-isolated thermal interface material (also known as electrically conductive TIMs) must be used to ensure proper grounding. Length of mains cable The length of the mains supply cable from the module is approximately 25 cm. The length of the extension cable outside of the luminaire is not specified. Starting characteristics The system can be switched on in milliseconds, which is a general characteristic of LED based systems. Unlike conventional CFL s, there is no observable start up time. Low and overvoltage The modules can withstand a voltage fluctuation of +/- 10% with no safety issue and no abnormal early failures. Inrush current The current that flows during the very first few milliseconds when switching on a luminaire or an entire lighting installation is called the inrush current. This current is very important when making the right choice of switch gear and fusing, e.g. circuit breakers, miniature circuit breakers (MCB). The inrush current is determined in part by the circuitry in use and in part by the properties of the mains supply, viz. the mainssupply impedance and the supply-cable resistance. The moment of switching in relation to the sine wave of the supply voltage also determines the value of the inrush current. The highest inrush current is when the driver is connected to the mains at the peak of the mains voltage. 22 Design In Guide Philips Fortimo LED Twistable Downlight Module Gen 2
