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 .

Packaging Technology

Thermal management is critical in high power LED applications .

With a thermal resistance from junction to case of 0.64º 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 .

Reliability

Designed from the ground up, Luminus LEDs are one of the

most reliable light sources in the world today . Luminus 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 LEDs are ready for even the most

demanding applications .

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 .

Technology Overview

Luminus 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 .

Testing Temperature

Luminus surface mount LEDs are typically tested with a 20 ms 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 .

Note 7: Luminus 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 lifetime 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 larger than 0.5 microseconds.

Note 8: Lifetime dependent on LED junction temperature. Input power and thermal system must be properly managed to ensure lifetime. See charts on pg 9

for further information.

Note 1: Listed drive conditions are typical for common applications . SBT-70 G,B devices can be driven at currents ranging from 1 A to

10.5 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 .

Note 2: All ratings are based on a junction test temperature Tj = 25ºC. See Thermal Resistance section for Tj definition.
