technology overview luminus big chip leds? beneft from innovations in device technology, chip packaging and thermal management. this suite of technologies give engineers and system designers the freedom to develop solutions both high in power and efciency. 2 pds-001574 rev 01 ? 2011 luminus devices, inc. - all rights reserved CBT-120-UV product datasheet photonic lattice technology luminus photonic lattice technology enables large area led chips to emit photons uniformly over the entire led chip surface. the intense optical power density produced by these uv big chip leds? facilitate designs which replace arc and halogen lamps where arrays of traditional high power leds cannot. for uv devices, luminus engineers the photonic lattice to maximize light extraction and to emit with a lambertian far-feld distribution pattern. the design maximizes efciency and allows for fexible optical designs. packaging technology thermal management is critical in high power led applications. with a thermal resistance from junction to heat sink of 0.7 c/w, luminus CBT-120-UV leds have the lowest thermal resistance of any led on the market. this allows the led to be driven at higher current densities while maintaining a low junction temperature, thereby resulting in brighter solutions and longer lifetimes. reliability designed from the ground up, luminus big chip leds are one of the most reliable light sources in the world today. big chip leds have passed a rigorous suite of environmental and mechanical stress tests, including mechanical shock, vibration, temperature cycling and humidity, and have been fully qualifed for use in extreme high power and high current applications. with very low failure rates and median lifetimes that typically exceed 10,000 hours, luminus big chip leds are ready for even the most demanding applications. environmental benefts luminus leds help reduce power consumption and the amount of hazardous waste entering the environment. all big chip led products manufactured by luminus are rohs compliant and free of hazardous materials, including lead and mercury. understanding big chip led test specifcations every luminus led is fully tested to ensure that it meets the high quality standards expected from luminus products. testing temperature luminus core board products are typically measured in such a way that the characteristics reported agree with how the devices will actually perform when incorporated into a system. this measurement is accomplished by mounting the devices on a 40oc heat sink and allowing the device to reach thermal equilibrium while fully powered. only after the device reaches equilibrium are the measurements taken. this method of measurement ensures that luminus big chip leds perform in the feld just as they are specifed. multiple operating points (4.2 a, 18 a, 30 a) the tables on the following pages provide typical optical and electrical characteristics. since the leds can be operated over a wide range of drive conditions(currents from <1a to 30 a, and duty cycle from <1% to 100%), multiple drive conditions are listed. CBT-120-UV devices are production specifed at 18 a. the values shown at 4.2 a and 30 a are for additional reference at other possible drive conditions. driving devices beyond recommended driving conditions shortens lifetime (see derating curves on page 5). luminus devices, inc. ? t 978.528.8000 ? www.luminus.com 1100 technology park drive ? billerica, ma 01821

CBT-120-UV devices can be driven at currents ranging from <1 a to 30 a and at duty cycles ranging from 1% to 100%. drive current and duty cycle should be adjusted as necessary to maintain the junction temperature desired to meet application lifetime requirements. note 4: unless otherwise noted, values listed are typical. devices are production tested and specifed at 18 a. values at 4.2 a and 30 a are for reference only. note 5: total fux from emitting area at listed peak wavelength. reported performance is included to show trends for a selected power level. for specifc minimum and maximum values, use bin tables. for product roadmap and future performance of devices, contact luminus. note 6: CBT-120-UV leds are designed for operation to an absolute maximum current as specifed above. product lifetime data is specifed at recommended forward drive currents. sustained operation at or beyond absolute maximum currents will result in a reduction of device life time compared to recommended forward drive currents. actual device lifetimes will also depend on junction temperature. refer to the lifetime derating curves for further information. in pulsed operation, rise time from 10-90% of forward current should be longer than 0.5?seconds. note 7: lifetime dependent on led junction temperature. input power and thermal system must be properly managed to ensure lifetime. see charts on page?5 for further information. note 8: special design considerations must be observed for operation under 1 a. please contact luminus for further information. note 9: caution must be taken not to stare at the light emitted from these leds. under special circumstances, the high intensity could damage the eye. luminus devices, inc. ? t 978.528.8000 ? www.luminus.com 1100 technology park drive ? billerica, ma 01821 cbt-120 product datasheet
