Development of a Workflow for Colored Ray Data

The importance of white LEDs has risen continuously over the past years. In many cases, disturbing color fringes appear on white LEDs with a blue chip and a yellow phosphor. To avoid this, different distribution of the blue and the yellow light has to be described for simulation. This means that colored ray files are necessary. A workflow and method for creating colored ray files is proposed and examined.

Optical Materials

Advanced Optical Plastics Materials for Diffusing Light/LED Lighting Applications

Plastic materials are used for many LED lighting applications. The optical properties of the diffusing material are crucial for designing high quality LED panel lights. Plastics manufacturers are continually improving the transmission rates while maintaining the diffusion properties and other material properties. Improvements allow for thinner optical sheets, resulting in part-weight and material-cost reductions as well as offering a more environmentally friendly solution. The latest developments and current state-of-the-art working toward UL 94 certification of V-0 will be discussed.

Thermal Transient Testing of LEDs for More Reliable SSL Products

An LED device’s reliability, useful operating lifetime and luminous flux are basically determined by the junction temperature; therefore, so is the lifetime and reliability of the final SSL application. Thermal transient testing is now supported by new industrial laboratory testing standards published by JEDEC.  Corner stones of this standard will be explained and application examples discussed. This includes measurement of the RthJC, test-based thermal modeling of the LED package, hot lumens prediction, and monitoring of degradation of the thermal interfaces during life-time test, to name just a few.

Cost Saving Potential with Automation and Well Designed Processes

The manufacturing of modern LED luminaires and conventional fixtures has some similarities as well as some distinct differences that result in added challenges. Automation, in combination with a well-conceived product design and process and well-matched components, allows for economical manufacturing without compromising production quality and, consequently, reliable, high performance, and high quality luminaires. The technical challenges, successful concepts and solutions will be presented, explained and discussed.

Managing Manufacturing and Supply Chain Challenges in LED Luminaire Design

Today’s luminaires are often complicated lighting systems using high powered LEDs which are powered by printed circuit boards. This causes several common challenges that arise in LED manufacturing. Such challenges are preferably mastered by partnering with design and manufacturing firms to leverage technology and improve time to market. The article shows how to manage these design, manufacturing and supply chain challenges and explains how to tackle the thermal management problem through innovations in PCB design and the use of different materials.

Special Topic:
Production Chain and Costs

Cost Issues in the SSL Production Chain - From Substrate to the Luminaire

Estimates of the global capacity for the manufacture of LED lights and output at each stage of production are widely different.  One important factor concerns the production of good dies from the substrate wafers – what fraction of the input sapphire or SiC is discarded? Then how much light is produced from each mm² of good die and how much light is needed to meet global demands? An analysis of the complete value chain, extending to R & D costs, profit margins and sales volumes is used to highlight issues of price premiums over traditional technologies, supply-demand imbalance and regional differences between China, Europe and the USA.
