SSM-80 Product Datasheet
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
For red, green and blue LEDs, the photonic lattice structures
extract more light and create radiation patterns that are more
collimated than traditional LEDs. Having higher collimation
from the source increases optical collection efficiencies and
simplifies optical designs.
temperature, thereby resulting in brighter solutions and longer
lifetimes. The package is easy to use, and ready to be mounted
in the lighting system.
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.
Thermal management is critical in high power LED applications.
With a thermal resistance from junction to case of
1.0º C/W. Luminus SSM-80 package is designed with high
quality materials to provide customers with industry leading
package thermal conductivity. This allows the LED to be driven
at higher current densities while maintaining a low junction
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.
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.
Luminus surface mount LEDs are typically tested with a 20mSec
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 (0.7A, 1.4A, 2.0 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 less than 350mA
to 2.0 A, and duty cycle from <1% to 100%), multiple drive
conditions are listed.
SSM-80 LEDs are production tested at 1.4 A. The values shown at
0.7A and 2.0A are for additional reference at other possible drive
