Understanding Luminus LED Test Specifications

Every Luminus LED is extensively tested at full current to ensure that it meets the high quality standards expected from Luminus’

products.

Technology Overview

Luminus Devices’Projection Technology (PT) is an innovative solid-state light source created to replace arc lamps in projection systems,

enabling a new category of lamp-free projectors. Enabled by Luminus technology, our LED chipsets represent a major breakthrough in

brightness that delivers all the benefits of solid state light sources in projections applications, including wide color gamut for vivid

colors, exceeds NTSC, Environmentally friendly technology (Mercury-free), instant start and re-start with no more wait time, high

reliability; no more lamp replacement , and electronic control of color points and light intensity on a frame by frame basis. Luminus LED

products benefit from numerous innovations in the domain of packaging, thermal management and optical coupling that allow

designers to achieve efficient light engine designs and deliver high screen brightness.

Testing of Luminus LEDs

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 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.

PackagingTechnology

Thermal management is critical in high power LED applications.

With a thermal resistance from junction to case of 0.4º C/W,

Luminus PT-121 LEDs can be driven at higher current densities

while maintaining a low junction temperature, thereby resulting

in brighter solutions and longer lifetimes.

Reliability

For high power operation, 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. (Please refer to Luminus’ Reliability

application note for more information.)

Environmental Benefits

Luminus LEDs help reduce power consumption and the

amount of hazardous waste entering the environment. All

Luminus LED products are RoHS and REACH compliant and free

of hazardous materials, including lead and mercury.
