Looking for the Best Thermal Solution for CSP Module Designs

Looking for the Best Thermal Solution for CSP Module Designs Chip Scale Package (CSP) LED technology is not new but while it has been used for a while in TV backlighting applications, it is relatively new to lighting applications. In many respect CSPs are a new world for lighting module manufacturers as they are smaller, usually don’t have any ESD protection, have different light distribution, and, last but not least, have a smaller heat dissipation area. The latter asks for re-thinking the traditional thermal design for modules. Dr. Giles Humpston, Applications Engineer at Cambridge Nanotherm, explains in detail why CSP LEDs present a significant thermal challenge for module designers and outlines some fundamentals in calculating the thermal flow required to keep CSP LEDs cool.

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.

Prof. Shuji Nakamura - The Future is Laser Lighting

Prof. Shuji Nakamura - The Future is Laser Lighting PROF. NAKAMURA SAID: "For violet LEDs we reach about 50-100 Acm-2 but the laser diode uses 3-10 kAcm-2 which is about 1,000 times higher than blue LEDs. This leads to very tiny chips in combination with the same phosphors such as YAG types. The light output is about 1,000 times higher than conventional LEDs with the same chip-size". Read more »
