Smart LED System in Package through Wafer Level Integration Approach

Smart LED System in Package through Wafer Level Integration Approach It is believed that LEDs will dominate all lighting applications in the near future. Integration and packaging are the two critical issues that, if resolved, will enable efficient and reliable solutions for lighting requirements. Z. Kolahdouz, H. van Zeijl, and G. Q. Zhang from the Institute of Microsystems and Nanoelectronics (DIMES) at the Delft University of Technology, and M. Kolahdouz from the Thin Film Laboratory and Nano-Electronics at the Department of Electrical and Computer Engineering of the University of Tehran show that wafer level packaging is a promising method to ensure lower cost, higher scale, and superior yield. A new integration approach of a smart unit of LED lighting is introduced: LED System in Package (SiP). Read more »

A Standardized Open Platform Is Key to the Future of Smart Lighting System Design

A Standardized Open Platform Is Key to the Future of Smart Lighting System Design The LED industry’s pace of evolution is more prevalent now than it has ever been. The shift from traditional standalone LED bulb lighting to fully connected digital LED systems is upon us and is transforming the industry for the better. For years, LED manufacturers have focused on driving cost down rather than focusing on improving quality, but with the advent of connected lighting, smart lighting and human-centric lighting, the focus has shifted back onto quality. Dr. Kyeongik Min, Principal Engineer in the LED business team at Samsung Electronics, explores how the LED industry can accelerate the transition from standalone lighting to fully connected lighting through a deeper understanding of current market trends.

Lighting Up Smart Cities, Dr. Wu Chou, Huawei

Lighting Up Smart Cities, Dr. Wu Chou, Huawei Although streetlights have been associated with cities for more than a thousand years, they are rarely considered for functions other than luminary purposes. One of the distinct features of streetlights is their geographic location. In particular, streetlights follow the roads and streets that are the arteries of the city, and at night they outline the city so it can be seen from many miles away. Read more »

Flicker: Standards and Test Methods

Flicker: Standards and Test Methods Much has been written and said about Temporal Light Artifacts (TLAs). What is essential about TLAs is that they consist of flicker and/or stroboscopic effects induced by a light stimulus whose luminance or spectral distribution fluctuates with time and causes undesired changes in visual perception for an observer in a certain environment. Walter Parmiami, Senior Engineer at UL International Italia S.r.l., discusses the current status of regulations and measurement standards and proposes a certification to help manufacturers to generate user confidence, and consumers and specifiers to find the right product for an application Read more »
