CBT-120-UV Product Datasheet
Technology Overview
Luminus Big Chip LEDs™ benefit 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 efficiency.
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-field distribution pattern. The design maximizes efficiency
and allows for flexible optical designs.
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 qualified 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 Benefits
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.
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 Specifications
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 field just as they are specified.
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 specified 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).

Listed drive conditions are typical for common applications. 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.
Unless otherwise noted, values listed are typical. Devices are production tested and specified at 18 A. Values at 4.2 A and 30 A are for reference only.
Total flux from emitting area at listed peak wavelength. Reported performance is included to show trends for a selected power level. For specific
minimum and maximum values, use bin tables. For product roadmap and future performance of devices, contact Luminus.
CBT-120-UV LEDs are designed for operation to an absolute maximum current as specified above. Product lifetime data is specified 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 μseconds.
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.
Special design considerations must be observed for operation under 1 A. Please contact Luminus for further information.
Caution must be taken not to stare at the light emitted from these LEDs. Under special circumstances, the high intensity could damage the eye.
