LED Test & Measurement Services
Download BrochureOrb Optronix’ state-of-the-art LED measurement services are performed within Orb’s onsite photometery and radiometery laboratory. We are unique in that we provide complete electrical, thermal and optical characterization of Light Emitting Diodes (LEDs) and LED products. LED light output varies depending upon electrical input characteristics, temperature, lifetime, and manufacturing variability. We help our customers to quantify LED performance as a function of many variables for their LED part qualification testing, product development engineering, incoming inspection and quality control needs. Our photometry and radiometery metrology lab is fully NIST traceable and equipped to handle the demands of LED testing over a wide range of electrical drive and thermal variables. Since LED light output, in terms of wavelength and total flux, is dependent on so many variables, complete LED characterization is often required for product development of products utilizing LEDs. LED Manufacturer’s spec sheets often lack pertinent data about true performance under real operational conditions. Orb Optronix’ LED Test & Measurement Services solves this problem for you.

Common Purposes for Testing LEDs
Product Development Data: Since LED light output, in terms of wavelength and total flux, is dependent on so many variables, complete LED characterization is often required for product development of products utilizing LEDs. Orb Optronix applies LED test and measurement to product development cycle for three reasons:
- Design Optimization
- Product Robustness
- Product Lifetime
LED Qualification Testing: We perform complete LED chanarcterization of discrete LEDs involving flux output, dominant wavelength, peak wavelength, chromaticity coordinates, and spectral bandwidth as a function of forward current, forward voltage, ambient air temperature (Ta), Case Temperature (Tc), and time. This includes electrical input parameters in pulse width modulated mode such as frequency and duty cycle.
Incoming Inspection Testing: We perform LED burn-in for our customers as well as develop incoming test procedures and protocols for LED burn-in for incoming inspection.
Quality Control Inspection: We perform tests of LED device and array output as a function of ambient air temperature to ensure that products and subsystems pass light output characteristics as a function of environmental conditions.
