TestingTemperature

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 (3.15, 9.0 A and above)

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 1.0 A to

18.0 A, and duty cycle from <1% to 100%), multiple drive

conditions are listed.

SST-90 LEDs are production tested at 3.15 A. The values shown

at 9.0 A are for additional reference at other possible drive

conditions.

Understanding Luminus LED Test Specifications

Every Luminus LED is fully tested to ensure that it meets the high quality standards expected from Luminus’products.

SST-90-R Product Datasheet

LuminusTechnology

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.

PackagingTechnology

Thermal management is critical in high power LED applications.

With a thermal resistance from junction to case of 0.5°C/W.

Luminus SST-90 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 chip technology, packaging and thermal management. These

breakthroughs allow illumination engineers and designers to achieve solutions that are high brightness and high efficiency.
