Samsung Electronics Co., Ltd. today announced that it has begun mass producing a new mid-power LED package, the LM301B, which features the industry’s highest luminous efficacy of 220 lumens per watt. The package is well suited for a range of LED lighting applications including ambient lighting, downlights and most retrofit lamps.

Samsung was able to achieve its industry-leading efficacy (@ 65mA, 5000K, CRI 80+) by incorporating an advanced flip-chip package design and state-of-the-art phosphor technology. The LM301B’s flip-chip design uses a highly reflective layer-formation technology to enhance light efficacy at the chip level. Also, a complete separation between its red phosphor film and green phosphors allows minimal interference during the phosphor conversion process, resulting in higher efficacy than conventional phosphor structures. These combined technology enhancements enable a 10-percent increase in overall efficacy compared to competing 3030 platform packages, without compromising on premium-quality light output.

“With our LM301B, we are able to deliver even greater mid-power value and help lower the total cost of ownership for LED lighting manufacturers,” said Jacob Tarn, Executive Vice President of LED Business Team at Samsung Electronics. “Thanks to advancements like the LM301B, Samsung will continue to drive innovation in next-generation LED technologies.”

Samples of the LM301B are available now.

LG Innotek succeeded in mass-producing ultraviolet (UV) LED module that sterilizes the inside of water purifier faucet aerators.

The company started to mass-produce the UV LED module for sterilizing water purifier faucet aerators at the end of the last month. This product is built in LG Electronics’ new direct water purifier “PuriCare Slim Updown” launched in March in the Republic of Korea.

A water purifiers faucet aerator always holds a small amount of water. This part is prone to contamination due to the growth of germs that come in with the influx of air. However, it was difficult to install a sterilizer inside a faucet aerator because its space is too narrow.

LG Innotek developed a UV LED module customized for the faucet aerator that has strong sterilizing power and is harmless.

This module directly sterilizes the water inside faucet aerator with ultraviolet rays. The product is 1.5cm in width and 3.7cm in length and can be mounted in the small space inside the water purifier.

The product kills 99.98% of germs when a faucet aerator is exposed to ultraviolet rays for 5 minutes. This result was obtained by sterilizing a faucet aerator with 278nm wavelength.

UV LED module is also harmless since it uses only ultraviolet rays for sterilization without any chemicals or heavy metals. Also, unlike a mercury UV lamp, you don’t need to worry about breaking it.

This product is convenient to use as it allows you to control ultraviolet rays quickly and accurately. As soon as its sterilization function is activated, ultraviolet rays are released at peak performance. On the contrary, a mercury UV lamp requires about 2 minutes of warming period.

LG Electronics’ direct water purifier installed with this module allows you to sterilize faucets in an instant by pressing the “Self Care” button anytime. It also performs automatic sterilization every 1 hour.

LG Innotek plans to actively expand the application of UV LEDs to various products. The company already developed a 280nm UV-C LED that has the power of 70mW for the first time in the world.

The company has already secured a product line-up with products that are optimized for different applications, including 365nm, 385nm, 395nm and 405nm UV-A LEDs for general industry and 305nm UV-B LED for biomedical field as well as 280nm UV-C LED for sterilization.

Ho-rim Jung, the vice president of LED marketing division, said, “Our UV LEDs will increase the value of the end products that are installed with them and allow us to care for the health of users in a smart way.”

According to Yole Development, a market research firm, the global market for UV LEDs is expected to grow more than seven folds from USD 130 million in 2015 to USD 1 billion in 2021. Especially, the UV LEDs for water purification is expected to occupy 60% of the said UV LED market.

On March 31, 2017, Seoul Semiconductor Co., Ltd (Seoul) filed a patent infringement lawsuit in Germany in the District Court of Düsseldorf against Mouser Electronics Inc. (Mouser), a global electronic components distributor, asserting infringement of an LED patent.

According to the complaint, the infringement involves products from Mouser – LEDs for high-power light emission – manufactured by multiple LED companies, including Everlight Electronics Co., Ltd, a global top-10 LED maker. In the lawsuit, Seoul has sought a permanent injunction, damages, and recall and destruction of the alleged infringing products.

The asserted patented technology serves to efficiently extract light emitted from the internal LED structure by treating LED chip surfaces, thereby significantly improving light intensity and brightness. This patented technology has been widely used for various high-power LED applications, such as automobile lighting, cell phone flash lights, outdoor lighting, UV LED appliances, and others.

“The asserted patent is considered an essential technology for manufacturing high-power LEDs and has been widely used in various LED applications,” said Ki-bum Nam, Vice President of the Lighting Business Department at Seoul Semiconductor. “Seoul has actively enforced our patent rights against products that infringe high power LED technology. To create fair market competition and promote technological innovation, we continually take actions necessary to deter such infringement and protect our intellectual property,” Nam added.

According to the Institute of Electrical and Electronics Engineers (IEEE), among the companies that exclusively manufacture LED components, Seoul Semiconductor was the only one to be selected in the 2013 Semiconductor Manufacturing Patent Power Ranking. Seoul Semiconductor was also selected for the same category in 2012. IEEE’s patent power scorecards for each industry segment are based on the evaluation of the patent portfolios of more than 5000 leading commercial enterprises, academic institutions, nonprofit organizations, and government agencies worldwide. They take into account not only the size of the organizations’ patent portfolios, but also the quality of their patents with regard to growth index, impact of their patents, originality, and general applicability of the patents.

According to market research firm IHS, the LED penetration rate in automobile headlamps is expected to increase sharply to 32.3 % by 2021 from the current penetration rate of 16.4%. This high-power LED technology is already being used for exterior automobile lighting including headlights and daytime running lights. Furthermore, it is expected to become a significant technology for electric vehicles and autonomous vehicles, which require high-power LED lighting with high heat dissipation for energy efficiency.

In addition, this high-power LED technology applies to LEDs for mobile phone flash lights, which require higher light intensity. Because margins for LEDs used in flash applications are higher than those for backlights, this segment of the LED market for mobile phones has still grown steadily despite the overall decline in the IT sector LED market.

Further, this high-power LED technology is widely applicable to general lighting products for outdoor illumination, as well as commercial and industrial lighting systems, because such technology substantially enhances light efficiency and improves the brightness per unit area obtained from the LED. The technology is also widely used in manufacturing UV LEDs for sterilization, purification and curing processes. The UV LED application market is expected to grow rapidly, reaching $800 million by 2020.

Combined sales for optoelectronics, sensors and actuators, and discrete semiconductors increased 2% in 2016 to reach a seventh consecutive record-high level of $67.9 billion, but growth rates in the three market segments were all over the map last year. Optoelectronics sales fell 4% in 2016, primarily because of the first decline in lamp devices in 15 years due to an oversupply of high-brightness light-emitting diodes (LEDs) for solid-state lighting applications, but the slump was offset by a 16% increase in revenues for sensors and actuators along with a modest 4% rise in discretes, according to IC Insights’ new 2017 O-S-D Report—A Market Analysis and Forecast for Optoelectronics, Sensors/Actuators, and Discretes.

The new 360-page report shows O-S-D products generated 19% of total semiconductor sales in 2016, with the rest of the dollar volume coming in integrated circuits ($297.7 billion, which was a 4% increase from 2015).  IC Insights believes optoelectronics, sensors/actuators, and discretes sales will stabilize in 2017 and gradually return to more normal growth rates in the 2016-2021 forecast period of the new O-S-D Report (Figure 1).

Slight improvements in the weak global economy, steady increases in electronics production, and new end-use applications—such as wearable systems, billions of connections to the Internet of Things (IoT), the spread of image recognition in all types of equipment, and the proliferation of LED lighting around the world—are forecast to lift the three O-S-D markets in the next five years to $92.2 billion, which is a compound annual growth rate (CAGR) of 6.3% from 2016 compared to a projected CAGR of 5.7% for ICs.  The newly released 2017 O-S-D Report offers detailed market forecasts of the optoelectronics, sensor/actuator, and discretes market segments through 2021. A summary of how the three O-S-D market segments performed in 2016 and their outlooks for 2017 are shown below.

Optoelectronics sales fell 3.6% in 2016 to $33.9 billion, suffering their first setback in eight years. Sales of lamp devices, the largest optoelectronics product category, declined 8%.  Meanwhile, an oversupply of high-brightness LEDs for solid-state lighting applications also dragged the market down. The downturn is expected to be short lived as image sensors, especially those made with CMOS technology, are in the midst of a major new wave of growth, driven by new embedded cameras and digital imaging applications in automotive, medical, machine vision, security, wearable systems, and user-recognition interfaces.  Laser transmitters are also hitting new record-high sales because of the build-out of high-speed optical networks for huge increases in Internet traffic, digital video transmissions, cloud-computing services, and billions of new IoT connections in the coming years. Total optoelectronics sales are expected to grow 7.5% in 2017 to reach a new record high of $36.5 billion.

Sensors/Actuators, the smallest and until recently the fastest-increasing semiconductor market, ended four straight years of severe price erosion in 2016 and finally benefitted from strong unit growth. Sensors/actuator sales climbed 15.9% to a record-high $11.9 billion.  All major sensor product categories (pressure, acceleration/yaw, and magnetic sensors) and the large actuator segment saw double-digit sales growth in 2016.  The sensors/actuators market is projected to rise 7.8% in 2017 to reach a new record-high level of $12.8 billion.  In the next five years, sensors/actuators sales are forecast to be driven by the spread of automated embedded-control functions in vehicles (including autonomous driving capabilities), flying drones, industrial and robotic systems, home electronics, and measurement units being tied to IoT.

Discretes, the semiconductor industry’s oldest market, returned to normal growth in 2016 with sales increasing 4.2% to $22.1 billion.  In the last seven years, worldwide discretes sales have swung back and forth between strong increases and declines because systems manufacturers tend to abruptly cancel purchases whenever the economy and end-use product markets appears to be slowing, but then quickly resume buying to replenish factory inventories once the outlook improves.  With inventories being replenished in much of 2016, growth returned to five out of the six discretes product categories—power transistors, small-signal transistors, diodes, rectifiers, and miscellaneous “other” discretes group. The only sales drop in discretes was recorded by thyristors.  Total discretes revenues are forecast to rise 4.7% in 2017 to a new record-high $23.1 billion.
