Seoul Semiconductor Made the Jump to GaN Substrate, nPola May Rock Sapphire Substrate Industry

In July 2012, Seoul Semiconductor (SSC) announces a new LED product called “nPola,” which takes SSC more than ten years to develop. The product features the non-polar technology that increases brightness levels 5 times over existing LEDs. Currently most mass-produced LEDs’ luminous efficacies are around 100lm, but SSC’s nPola product’s luminous efficacy reaching 500lm, five times higher. Simply put, a 60W equivalent LED light bulb usually requires 10-20 LEDs, but it only needs 1-2 LEDs if adopting nPola product. According t...

Introduction to LEDs’ Basics

By Scott Patterson Light bulbs are seemed everywhere, and there are more than 20 billion light bulbs around the world right now. On an average that for every one person, there would be three light bulbs. In the future, we can expect a replacement of all the current lightbulbs with those of LEDs. The reason for the occurrence of this replacement is due to the fact that LEDs’ efficacy is multiple times higher than those of incandescent light bulbs. LED is possible in reproduce the theoretical limit of the conversion from electricity to light set by physics. LEDinsid...

Resistance in Adapting Energy Efficient Lights in the U.S.

By Scott Patterson In the U.S., government and environment activists are pressuring its people to convert from using old traditional incandescent lamps to LEDs (Light-Emitting Diodes) and CFLs (Compact Florescent Lamps). The public resist the notion that their freedom of choosing the type of lights they can use being strip away. Radio talk-show and TV-show hosts have rebelled and said that the new policy is unconstitutional. The government has no rights to tell its people what kind of light they can use.   This adaption process will take time as what we hav...

LED Lighting Regulation in 2012

by Paul Williams Greph Credit: U.S. Department of Energy The Energy Independence and Security Act of 2007 put many changes into motion for the lighting industry. The most significant change is a required 25 percent increase in the energy efficiency of light bulbs. Since manufacturers are currently unable to increase incandescent bulb efficiency by such a large percentage, the end result is essentially the phased elimination of this type of bulb. In January of 2012, the manufacture of 100-watt incandescent light bulbs that fail to meet the new efficiency standard wi...

A Lot Can Happen in Just 20 Years: Where Exterior Lighting Was Then & Where It Is Now

To give you an idea of what the new generation of LED-based exterior lighting can mean to your projects, think back to what your life was like in 1990. That was over 20 years ago. Your cell phone, if you had one, was so big and heavy, carrying it probably qualified as an exercise program. Businesses and governments threw tons of dollars at something known ominously as Y2K, which was supposed to throw us back into the Stone Age. (It didn’t, but they still spent billions on new IT systems).  The washing machine and dryer you bought that year? They’re probabl...

Sizing Up Circuit Protection for LED Strings

By Teddy To, Product Manager and Phillip Havens, Segment Manager • Littelfuse, Inc. As LEDs find their way into more outdoor applications they are at higher risk for ESD and other electrical transients. HB LEDs (those with sapphire or SiC substrates and in the future AlN and GaN substrates) are especially susceptible, and when the first LED in a string fails, the whole string goes dark. Few engineers know all the considerations of specifying circuit protection for LED strings. For example, a recent category of devices, called open LED protecto...
