CBT-90-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.
Luminus Technology
Luminus’ 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 LEDs™ facilitate
designs which replace arc and halogen lamps where arrays of
traditional high power LEDs cannot.
For UV devices, Luminus engineers the LEDs™ 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 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.
Packaging Technology
Thermal management is critical in high power LED applications.
With a thermal resistance from junction to heat sink of 0.9°C/W,
Luminus CBT-90-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.
Environmental Benefits
Luminus LEDs help reduce power consumption and the amount
of hazardous waste entering the environment. All 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 measuring the device while fully powered.
This method of measurement ensures that Luminus Big Chip
LEDs perform in the field just as they are specified.
Multiple Operating Points
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 22.5 A, and
duty cycle from <1% to 100%), multiple drive conditions
maybe listed.
CBT-90-UV devices are production specified at 13.5 A. Driving
devices beyond recommended driving conditions shortens
lifetime (see derating curves on page 6).

Data verified with NIST calibration standard.
All data are based on test conditions with a constant heat sink temperature T
hs
= 40°C under pulse testing conditions. Listed drive conditions are
typical for common applications. CBT-90-UV devices can be driven at currents ranging from <1 A to 22.5 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. See Thermal Resistance section for T
j
and T
hs
definition.
Unless otherwise noted, values listed are typical. Devices are production tested and specified at 13.5 A.
Total flux from emitting area at listed peak wavelength. Reported performance is included to show trends for a selected power level. For product
roadmap and future performance of devices, contact Luminus.
CBT-90-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 6 for further information.
Special design considerations must be observed for operation under 1 A. Please contact Luminus for further information.
