Thesis work 30hp Development of LM80 Test Station for LED Light Sources

Introduction:
A diploma work is an excellent way to get closer to Traton R&D and build relationships for the future. Many of today's employees began their Traton career with their diploma project. The subject reflects Traton’s need for development and the results are always highly appreciated. 

Location:
Traton R&D TGREEPCM, Environmental Verification Laboratory, Scania Technical Center, Södertälje. 20 min from Stockholm Central with regional trains (Mälartåg, SJ).

About the Scania group:
The EEPCT group at Scania performs accelerated ageing test of vehicle parts that contain electrical or electronic components. This includes e-machines, lithium-ion propulsion batteries, charging inlets, computer screens, lamps, USB-chargers, LIDAR etc.

Background:
LM80 is a standard used to evaluate the lifetime and light quality of LED light sources over time. To enable in-house testing, we are looking for a motivated thesis student to help design and build a complete LM80 test station.

Objective:
The goal of the project is to design, build, and validate a test environment that enables long-term measurement of LED components according to the LM80 standard. The focus will be on logging and analyzing:
•    Temperature (component and ambient)
•    Current and voltage (to monitor operating conditions)
•    Light quality (intensity, color temperature, color rendering)

Tasks:
•    Design of the test setup based on the 19-inch rack standard, including selection of sensors and measurement equipment
•    Implementation of a data logging system (e.g., using LabVIEW, Python, or similar)
•    Calibration and verification of measurement data
•    Documentation according to LM80 requirements
•    Presentation of results and recommendations for future testing

Job description:
•    Literature study of the field
•    Interviews of internal and external experts
•    Example design of a setup
•    Can data be used for Prognostics and Health Management?
•    Calculate the expected accumulated energy savings with an increased number of EV’ over the coming ten years.
•    Report writing and presentations.
•    The project can be a collaboration with other internal groups at Traton or external stakeholders 
 
Who are you:
You are a master’s student in Electrical Engineering, Engineering Physics, Mechatronics, or a related field. You have:
•    Interest in electronics, measurement technology, and lighting
•    Basic knowledge in programming and data acquisition
•    Preferably knowledge in LIN, CAN and PWM protocols
•    Ability to work independently and in a structured manner
•    Good communication skills in English and/or Swedish

What do we offer:
•    Opportunity to work with real components and test environments
•    Supervision by experienced test engineers
•    Insight into product development in the automotive industry
•    Chance to influence future test strategies
