Technology Overview
Luminus Big Chip LEDs™ benefit from a suite of innovations in the fields of LED die technology, packaging and thermal management.
These breakthroughs allow illumination engineers and designers to achieve solutions that are high brightness and high efficiency.
Luminus Technology
Luminus’ 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 case of 0.7º C/W,
Luminus SBT-70 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 surface mount LEDs are typically tested with a 20 msec
input pulse and a junction temperature of 25ºC. Expected flux
values in real world operation can be extrapolated based on the
information contained within this product data sheet.
Multiple Operating Points (7.0 A, 10.5 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 from1A to 10.5 A, and
duty cycle from <1% to 100%), multiple drive conditions are
listed.
SBT-70 White LEDs are production tested at 10.5 A. The values
shown at other current conditions are for additional reference at
other possible drive conditions.
