converted for LED production with a small modification. These companies already have in-house expertise and technology associated with silicon-based processes.
“Many of the CMOS semiconductor manufacturers already have excellent inspection tools, unlike traditional LED companies,” Cho explains. “This could help increase their process yield through in-situ monitoring. However, it is unlikely the repurposing will happen overnight; instead we forecast a shift during the coming years.”
US demand for LED lighting to rise more than 10 percent annually
The lighting market is predicted to increase to $11.7 billion in 2017
According toFreedonia Industry Market Research’s report, “LEDs & High Efficiency Lighting,” US demand for high efficiency lighting is forecast to increase more than 10 percent annually to $11.7 billion in 2017.
This will be supported by technological improvements and regulatory changes designed to lower electricity used in lighting applications.
The US market for high efficiency lighting continues to adjust to the provisions of the Energy Independence and Security Act (EISA) of 2007, which is leading to a phase- out of traditional incandescent lamps and supporting demand for products such as LEDs and compact fluorescent lamps.
Technological innovations that are improving the performance of LEDs and many types of high efficiency lamps are also supporting demand. In addition, particularly in the LED segment, improvements in manufacturing are leading to lower purchase prices for many products, thereby boosting market penetration for these efficient lighting products.
However, because high efficiency lighting products have much longer useful lives, the average replacement rate will decrease over time, eventually depressing high efficiency lighting demand.
LEDs to be fastest growing high efficiency lighting
Demand for LEDs will grow the fastest of any high efficiency lighting product through 2017. Increased penetration in many residential and non-residential building applications, as well as in the outdoor lighting market, will support advances. While the high initial price of LEDs has hindered their adoption in many traditional
On November 22nd, 2013, Nichia Corporation filed an amended complaint in its on-going patent infringement lawsuit against Taiwanese LED manufacturer Everlight Electronics Co., Ltd. and Everlight’s U.S. subsidiary

lighting applications, technological innovations that reduce costs and improve performance will make these products increasingly competitive.
The market for other energy efficient linear fluorescent lamps will also register strong growth, supported by heightened penetration of T5 and T8 lamps, in place of less efficient T12 products. In addition, the rebound in non-residential building construction will provide some prospects.
Building market to offer best growth opportunities
Through 2017, the building market for high efficiency lighting products will post especially strong growth, supported by a shift to higher value, longer lasting lighting products and driven in part by rising efficiency standards for lamps.
Residential demand will be bolstered by the replacement of less efficient lighting that has been phased out due to EISA. Businesses, institutions, and government entities will turn to high efficiency lighting products to lower energy expenses and to reduce the labour costs of replacing lighting products. Over the longer term, the market will be restrained by the longer service lives of LEDs and newer lamp products, which will limit replacement demand.
Nichia ups the ante in patent war with Everlight
The Japanese firm has added another three patents and two more defendants in its patent infringement lawsuit against Everlight in the United States
