illumia®Pro3LED Characterization System
Simultaneous thermal,
optical, and electricalcharacterizationof LEDs

The illumiaPro3 is an integrating sphere spectroradiometer
designed specifically for the testing and characterizationof high-power LEDs. With Labsphere’s powerful Integral®
software control, it’s a turnkey solution with embedded
routines that guide the user through industry test methods
and standards, yet completely flexible for research,development, and quality inspection.
The 0.5 m integrating sphere spectrometer, coated withLabsphere’s Spectraflect® diffuse white coating, comesstandard with a 2π measurement geometry and is fittedwith a thermal tech controller, industry-leading source
meter, and Labsphere’s stray light corrected spectrometer,
for LIVT, pulsed modes, and DC testing of high-power LEDs.

Integral Software
Included with the illumiaPro3 System, Integral provides apowerful, yet easy-to-use menu-driven operating environment.
It allows users to control the LED temperature and operating
current and voltage at specified ranges. This control enables thesoftware to measure and characterize the device under test (DUT)
over a wide range of temperatures. The software simultaneously
collects electrical, optical, thermal and total spectral flux data
which is graphed and viewed on screen or can be exported forfurther analysis.

LED LIVT with illumiaPro3
Fully characterize LEDs with independent control andtest of forward and reverse voltage, LED drive current
and temperature, and lumens with illumiaPro3 LIVT
sweep features.
Measurement Functions:• ILV @ constant T: step & control I, stabilize T, measure L & V• VLI @ constant T: step & control V, stabilize T, measure L & I• TLV @ constant I: step & control T, stabilize T, measure L & V• TLI @ constant V: step & control T, stabilize T, measure L & I• ILV/T: perform ILV @ constant T, step T and repeat at each T• VLI/T: perform VLI @ constant T, step T and repeat at each T
Key: L = Lumens, V = Voltage, I = Current, T = Temperature

LM-85 Testing with illumiaPro3
The photometric measurement of high-power LEDs can bedifficult because they are highly sensitive to thermal operating
conditions. LED manufacturers normally use pulse operation,
however, highpower LEDs in actual lighting products, areoperating in DC and at much higher temperatures where theirphotometric and colorimetric values tend to deviate significantly
from those at the room temperature condition. To assist users,
LED manufacturers make efforts to provide data on thermal
characteristics for higher operating temperatures; however,
because LEDs are usually binned by LED manufacturers fortheir optical and electrical characteristics at Tj equal to 25 °C,
manufacturer data for higher operating temperatures is oflimited use. To address the issue LM-85 was created to provide
reproducible measurement methods of LEDs at a given junction
temperature in pulse or DC mode and provides the grounds forthe specification of LEDs at high-temperature conditions.
LM-85 describes the procedures to be followed and precautions
to be observed in performing accurate measurements of totalluminous flux, total radiant flux (optical power), total photon
flux, electrical power, luminous efficacy, color quantities, andwavelength characteristics of high-power LEDs, including whiteLEDs and single-color LEDs. It covers LED packages, including
those with multiple chips and remote phosphor LED packages.
It also covers LED arrays or modules including remote-phosphor
LED arrays or modules. IllumiaPlus3 guides users through LM-85
stabilization, electrical, optical, and thermal control for pulse
operation as well as steady DC operation of LEDs.
