What this means in a practical sense, is that when operating at rated input (1watt approx.) the junction of a die in a cup prod- uct will attain a temperature that is 2 oC higher than a reference point on the mounting surface beneath it. In the case of a 10-watt Matrix product, the maximum temperature difference between any junction and the reference point is 25 oC (2.5 oC/w x 10w). The thermal path thus quantified is a composite of a number of thermally resistive elements in a series and or parallel configuration, but lumped together into a single parameter for convenience. For an end user of LED products then, this constan t allows the junction temperature to be determined by a simple measurement of the temperature of the mounting surface. Optek recommends that the design value of sus- tained die junction temperature be limited to 80 oC. In an ambient temperature of 25 oC, the board temperature of a 10-watt device must be constrained below 55 oC to comply with this recommendation, and for a 1-watt cup the board can theoretically operate at up to 78 oC. From the diagram above it can be seen that the hea t generated in the junction region follows a somewhat serial conductive path through the package to the major radiating surface – which in this example is a single sided PCB. Some additional radiation may occur directly from the upper surface of the package (not shown). This would be conducted upward from the die surface through the transparent encapsulating material to the package surface and be radiated from there. To all practical purposes this is a very minor effect. The polymer encapsulants in normal use are poor conductors of heat.

For the materials above, the respective contribution each makes to the overall thermal resistance (R θ j-b) is a function of the thickness of each material layer, and the surface area. Thermal Conductivity (TC) is defined to be the heat conducted in time (t), through thickness (T) in a direction normal to a surface area (A), due to a temperature difference ( δ T). Therefore TC= q/t x {T/[A x δ T]} and δ T = [Q x T]/[A x TC] where δ T = Temp. difference (K) Q = Power (w) A = Surface area (m 2) T = layer thickness (m) TC = Thermal Conductivity (w/mK) Theoretical Calculation (for 1 watt dissipated in a cup product via a single 40mil die) GaN Thickness approx 10 x 10 -6 = 1 x 10x10 -6/ 10 -6 x 150 Area 10 -6 = 0.07 K Substrate T = 60 x 10 -6 = 1 x 60x10 -6/ 10 -6 x 50 = 1.2 K Die attach T = 20 x 10 -6 = 1 x 20x10 -6 / 2x10 -6 x 10 A = 2 x 10 -6 = 1 Package T = 0.4x10 -3 = 1 x 0.4x10 -3/ 6x10 -6 x 350 A = 6x10 -6 = 0.19 Solder T = 60x10 -6 = 1 x 60x10 -6/6x10 -6 x 25 A = 6x10 -6 = 0.4 Total Calculated δ T = 2.86K

Assuming this is of the order of 200mw, the adjusted value of δ T is 2.29K. The calculation now assumes that all of the dissipation, 800mw of heat, is conducted along the thermal path, thereby ignoring any conduction and subsequent radiation that is not direction- ally normal to the surfaces considered, ie: conduction through the encapsulant material vertically away from the board, and conduction horizontally away from the heat source. The calculation also assumes that there is no contri- bution to thermal resistance at the boundaries between material layers. In practice it is improbable that perfect transfer will occur at these transition regions, even though the bonding between layers in this example are of high quality. In general, the calculation indicates that the measurements below are of the order of magnitude that can be expected. The alternate matrix product range is of a much mo re complicated thermal design, which does not lend it- self to a simple theoretical calculation similar to that shown above. There are multiple incident heat sources, parallel heat conduction paths, and significantly larger surface area for stray radiation, eg. Cup above has a surface area available for stray radiation of approximately, 25mm 2 per watt of input power. A 10-watt matrix product has approxi- mately 92.5mm 2 of exposed surface per input watt. Measurements The key to an accurate measurement of thermal resi stance is to obtain a reliable value for the junction tem- perature (Tj). Since the die itself is, and must be, encapsulated during testing, and the junction is contained within the structure of the die, direct measurement of the junction temperature by normal means is not possible. Two methods of non-contact thermography are available, both of which rely on emitted infrared detection. Infrared imagery by calibrated radiograph is a pos sibility; however, in the instance of a cup product only a small value of δ T is expected which makes accurate estimation of the actual temperature gradient difficult using col- orimetry. The alternative measurement type is digital infrar ed thermography. This means there is an inherent uncer- tainty in the calculation algorithm, which sometimes gives results considered unacceptably inaccurate. In this in- stance absolute accuracy is of secondary importance because the value to be determined is a temperature differ- ence ( δ T) which requires only relative values – any error in a first reading will also be present in subsequent read- ings that are about the same value. The difference between readings is accurate. The other significant drawback to infrared thermometers is a limitation to minimizing the spot size over which the measurement is made. This poses a difficulty for small assemblies like an LED cup, and in particular the added complication that the calculated temperature is an average value for the area being interrogated further com- plicates the issue. Another concern is sometimes raised about the ability of this type of instrument to detect a heated surface beyond the closest transparent radiating surface. This is a significant issue for far field measure- ments; however, it is simple to demonstrate that this does not hold true for the near field, and particularly when the incident beam has a known focal length. 10-Watt Lednium SMD OVTL09LG3x Series
