The use of LED emitters from a to generate statistical data. These forward single forward voltage category allows LED voltage categories have been identified as emitters to be connected in parallel to simplify “insufficient” data in the tables. external drive circuitry. For complete details on the Lumileds Lighting SuperFlux LED emitter A wide variety of forward current models can category ranges, please see AB207. be generated using the forward voltage data shown. Linear forward voltage models can The data shown below represents production be generated using two adjacent test currents forward voltage test data taken at five forward (i.e. 70 and 150 mA, 32 mA and 70 mA, or 8 currents for the SuperFlux emitters—30µA, 1 mA and 32 mA) using the equations shown in mA, 8 mA, 32 mA, and 70 mA for emitters built AB203. Diode equation forward voltage from 8/01 to 12/01 and future data is subject to models (as described in AB203A) can be change. For the SnapLed150 emitters, generated using three adjacent test currents production forward voltage test data is taken at (i.e. 32, 70 mA, and 150 mA; 8 mA, 32 mA, six forward currents—30µA, 1 mA, 8 mA, 32 and 70 mA; or 1 mA, 8 mA, 32 mA) using the mA, 70 mA, and 150 mA for emitters built from equations shown in AB203A. 8/01 to 10/01 and future data is subject to change. While this data was only taken on Nominal forward voltage models would be SuperFlux and SnapLED150 emitters, the generated using the “mean” or “50%tile” values SuperFlux data would also apply for SnapLED of forward voltage at the desired test currents. 70 emitters. “Worstcase” circuit analyses can be generated with two forward voltage models that simulate For each SuperFlux and SnapLED150 product the lowest forward voltage and the highest type, the data for these units were sorted into forward voltage at any forward current. For the different forward voltage categories using example the minimum forward voltage can be the non guardbanded production test limits. estimated using the “0.1%tile” or the “1%tile” Then, the statistics (i.e. mean, standard forward voltage values and the maximum deviation, minimum and maximum) were forward voltage can be estimated using the compiled for each forward voltage category. “99.9%tile” or the “99%tile” forward voltage values. Note that the number of units Note that the data represents production data corresponding to a normal distribution +/ 3 for about 60,000 to 130,000 units and 10 to 25 standard deviations (i.e. 99.74% of the total production lots per part number. The data was population) corresponds roughly to the number chosen such that each lot represents a different of units in the range from “0.1%tile” to “99.9% AlInGaP wafer. tile” (i.e. 99.8% of the total population). 2 For Monte Carlo simulations, individual test unit Linear or diode equation forward voltage data is available from Lumileds Lighting. This models can be constructed for each unit. Then data consists of the actual forward voltages of the Monte Carlo simulation would randomly the test units used to generate the statistical select combinations of units for each test data shown below. Thus, each datalogged unit simulation. has five or six values of forward voltage at the different test currents [30µA, 1 mA, 8 mA, 32 mA, 70 mA, and 150 mA (SnapLED150 only)].
