Lighting & LED

EAG’s analytical support services for lighting result in production cost savings, improved lot-to-lot product performance and accelerated product development. We provide world-leading support of research, development and fast-response production monitoring for both conventional and LED lighting manufacturing.

EAG’s laboratory in Eindhoven, The Netherlands has a long history in the field of lighting testing and analysis, supporting both conventional and LED lighting product development. Our Eindhoven experts provide consulting services for lighting products and raw materials, due to our vast knowledge of application conditions and regulations for lighting materials.

For both conventional and LED applications we offer:

Chemical compatibility

Testing of materials/components for their suitability to be used in a “chemical environment” (e.g. in industrial areas, by the sea, agricultural applications, hospitals, etc.)
Testing of materials/components resistance against cleaning agents, disinfection agents, aggressive gases or other chemicals.

Failure analysis and problem solving

Forensic analysis (in the lab) and on-site investigation to identify and understand the root cause(s) of failure
Root cause generation (conformation) in our reliability and materials laboratories
Support to address problems via material and/or process consultancy
Proving the validity of proposed solutions or hypotheses in our test laboratories

Materials reliability

Testing of material, component or product reliability (IP testing, salt mist exposure, HALT, drop & vibration testing)
Environmental testing (thermo shock & cycle, damp-heat test, UV & solar test)

LED Analysis and Consulting

We support LED analysis at all levels:

Level 0: LED wafer/die/chip
Level 1: Packaged LED die
Level 2: LEDs on PCB mounts
Level 3: LED modules or LED bulbs
Level 4: Luminaires

We offer the following range of services to answer questions and address issues related to all LED product component and materials at different manufacturing stages.

Compositional analysis

Identification and compositional analysis of polymers (e.g. silicones), metals, gases, LED phosphors, quantum dots, ceramics, contaminants, electrical components.

Contamination identification and control

Analysis of contamination in gases (e.g. gas composition in filled LED bulbs; air quality/cleanliness in industrial manufacturing areas)
Analysis of material outgassing (e.g. potentially harmful substances from cables, drivers, PCBs or other components)
Measuring cleanliness of products beyond just visual inspection
Witness testing to verify your product will meet industry, company or customer specifications. We are experts in testing if components and/or environmental conditions have negative interactions that may negatively influence product performance

Measurement of light technical parameters

Measurement of light technical parameters of a single LED and complete modules before, during and after testing (e.g. color temperature, color point, luminous intensity, radiation pattern, color over angle, etc.).

Other applications

Our lighting and LED expertise also enables us to successfully address issues in related industries which have components containing similar materials or where the products may also be exposed to harsh environments, e.g. automotive components, including lighting; photovoltaic/solar cells, thermal/solar concentrators/mirrors etc.

Conventional Lighting Analysis and Consulting

Our conventional lighting experts have years of experience troubleshooting and testing conventional lighting products, including:

(Ultra) high pressure discharge lamps
Fluorescent lamps
Disinfection UV lamps
Halogen lamps

These types of products often require compositional analyses, such as identifying and characterizing such components of conventional lighting materials:

Metals
Gases
Fluorescent powders
Emitter
Mercury consumption
Tungsten electrodes/materials
Pre-coats
Feed-through materials
Ceramics
Glass
Contaminants
Electrical components

Examples of quality control and contamination studies for conventional lighting products:

Analysis of gas composition and contamination in gas filled lamp (even in burning mode); inner and outer bulbs, air quality/cleanliness in industrial manufacturing areas and oven processes
Analysis of material outgassing, bake-out tests of volatile, potential harmful, substances from cables, drivers, PCBs or other components
Measuring cleanliness of products beyond just visual inspection
Support quality processes in production

Consultancy, training and coaching

Material consultancy
Training on site; for example, operation procedure handheld XRF instrument
Consultancy concerning international test standards on hazardous/certain substances
RoHS – REACH support

Surface Analysis for Lighting and LEDs

EAG offers surface and thin film characterization, to understand composition, surface contamination andsurface topography, as well as measuring thin film thickness, defects and optical properties.

Our analytical support for LED R&D includes packaging development and contamination analysis, in addition to burn-in and reliability testing to LM-80 standards.

EAG scientists are experts in the characterization of epitaxial films for identity, structure, grain size and orientation, composition, dopants and contaminants.

We offer a broad range of analytical services developed exclusively for LED characterization:

Layer thickness and density determination
Full wafer layer thickness mapping
Stress in epitaxial layers
Crystalline orientation
Depth profiling dopants and impurities
Measuring layer thickness and composition
Controlling common impurities (e.g. H, C and O) in MOCVD epitaxy with very low detection limits
Characterization of crystal quality of AlInGaP and InGaN MQWs
Cross-sectional analysis of the structure of LEDs
Examining the cross-sectional structure of LEDs
Full reverse engineering of finished LEDs
Problem solving in adhesion of metal stack onto semiconductor material
