CBT-140 Product Datasheet
Technology Overview
Luminus Big Chip LEDs™ benefit from a suite of innovations in the fields of chip technology, packaging and thermal management. These
breakthroughs allow illumination engineers and designers to achieve solutions that are high brightness and high efficiency.
Photonic Lattice Technology
Luminus’ photonic lattice technology enables large area LED
chips with uniform brightness over the entire LED chip
surface. The optical power and brightness produced by these
large monolithic chips enable solutions which replace arc
and halogen lamps where arrays of traditional high power
LEDs cannot.
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
60,000 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 0.25º
C/W, Luminus CBT-140 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 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.
Expected flux values in real world operation can be extrapolated
based on the information contained within this product data
sheet.

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 21.0A, and
duty cycles from <1% to 100%), multiple drive conditions may
be listed.
CBT-140 White LEDs are production tested at 21.0 A.
