Seoul Semiconductor Launches Smart Lighting LED Light Engine

Seoul Semiconductor a global leader in LED technology announced the release of a new LED light engine with Acrich 3 technology on August 27, 2014. The new light engine is comprised of an LED module with Acrich MJT 5050 series LED, Acrich3 IC technology, and an innovative heat sink and secondary optics. The Acrich light engine does not require a complex AC/DC converter and can be operated directly from the AC mains which simplifies designs, reduces component count and improves on the reliability of the luminaire. This new 30W Acrich light engine delivers a typical luminous flux of 3000 lumens at 120VAC operation at 5000K corresponding to a typical efficiency of 100 lumens per watt. When operated in a power compensation mode the Acrich3 technology can adapt to variations in the line-voltage as great as 20% and still deliver power-level regulation within 5% to ensure uniformity of the light output.

Furthermore, the new Acrich3 solution enables smart lighting control systems the Acrich3 technology can interface through a wide variety of wireless networks such as IEEE 802.15.4, WiFi, and Bluetooth to control dimming, and further optimize on energy savings. This IP67 light engine is available in various color temperatures and beam patterns.

Seoul Semiconductor Executive Vice President of Lighting sales division, Jay Kim has stated that, “The payback period for streetlights can be significantly reduced with this new Acrich light engine. By eliminating AC/DC converters in streetlights, maintenance costs can be lowered and reliability can be improved without compromising on price, quality and energy savings to dramatically improve the lighting experience for customers. This product will enable the market to come up with the next generation of high quality, energy efficient and competitively priced LED lamps.”

Copenhagen to Roll Out Smart LED Streetlight Project

Danish city Copenhagen plans to roll out a pilot project featuring smart LED lights, according to a Nature World News Report.

The city authorities recently announced a climate change plan to make Copenhagen “carbon neutral” by 2025 and slashing carbon emissions to insignificant levels. As part of these plans, the city is redesigning its streetlights.

The Danish Outdoor Lighting Lab (DOLL) a GreenLab by Photonics is to be opened within a month and expected to stretch for 5.7 miles (9.2 km) along the roads of suburb Albertslund.

The report highlighted the experiment is “a virtual free-for-all” of competing smart technology designs, about 25 companies have made reservations to field test product, according to Inhbabitat. Each lamp has its own IP address so it can be monitored independently.

In an interview with New Scentist, Robert Karliceck the director of the Smart Lighting Engineering Research Center at Rensselaer Polytechnic Institute in New York, suggested smart street lights can even act as toxin sensors in the air or maybe even survey unusual street activity that require police attention.

"Really smart street light systems are going to be much more about the sensors the street lights have, than the LEDs that happen to be in them. The technology is getting very mature very quickly," he said.

Only 10% of iPhone 6 Will be Using Sapphire Cover Glass

New rumors regarding limited usage of sapphire cover glass usage in iPhone 6 have emerged in Taiwan.

According to a Chinese-language Liberty Times report only one out of 10 of Apple's new iPhone 6 will be using the sapphire cover glass.

The report did not clearly indicate sources it turned to for the information. What can be gathered from the report is global sapphire substrate production capacity fall short of Apple iPhone 6 volume demands. Sapphire ingot manufacturers noted current global 2-inch sapphire substrate production capacity is only 10 million pieces (PCS). If other smartphone brands also follow in Apple’s footsteps and introduce sapphire cover glass into their products it could create sapphire substrate shortages.

The report reasoned, due to the lack of sapphire ingot production capacity (an observation LEDinside analysts have already pointed out last week), only 10 percent of iPhone 6 will be utilizing the material.

Although, Apple turned to GT Advanced Technology for exclusive sapphire ingot supply, it has still created a large supply and demand gap in the sapphire substrate industry, the report went on. Based on past experiences, Apple would be shipping at least 10 million smartphones a month after iPhone 6 hits store shelves. If all these phones come with the hard resilient material, sapphire substrate demands would exceed 40 million PCS per month. GTAT’s current monthly production capacity is about a tenth of that at 4 million PCS. The sapphire manufacturer has reached a production capacity bottleneck, and the estimations are considered generous since yield rates are not taken into consideration. Therefore, industry insiders believe only the high-end version Apple iPhone 6 will be equipped with sapphire glass covers.

In the none-Apple camp, Monocrystal, Rubicon, STC and other manufacturers have a monthly sapphire substrate production capacity of 10 million PCS to supply various applications. The current volume is sufficient to meet LED industry monthly demand of 3 million PCS and smartphone optic applications demands for lens and home buttons 1 million PCS.

Samsung and Chinese smartphone manufacturers tend to go after Apple specs. The sapphire ingot production capacity gap will further once these companies also start launching sapphire cover glass smartphones. Global smartphone demands, excluding Apple smartphones, has a shipment volume of 50 million. If 20 percent of these smartphones use sapphire substrate, sapphire demand will far exceed 40 million PCS, equivalent to four times the global sapphire ingot production capacity.

Many Chinese sapphire ingot manufacturers have started to expand production capacity, but there is no guarantee about the potential quality. This is also the main reason that Apple turned to GTAT for sapphire supplies, instead of searching for existing suppliers. The report pointed out, Apple’s exclusive partnership with GTAT prevents iPhone shipments from being affected by major price upticks and material shortages in the sapphire industry.

Production Issues Restrict Apple’s Sapphire Cover iPhone 6 Release

Despite Apple’s plans of launching the iPhone 6 in late 2014, optical demands in handheld devices failed to generate price upticks in the sapphire substrate industry, according to LEDinside, a research subdivision of market-research organization TrendForce.

Sapphire ingot, substrate and patterned sapphire substrate (PSS) prices have all dropped in July 2014, with some product prices down 5%-10% Quarter-on-Quarter (QoQ). The research organization noted optical demands lagged behind sapphire  manufacturers’ production expansion, and order volumes have fallen short of expectations. In the sapphire ingot industry, 2-inch ingot prices were down to US $3.5-$4.0, while 2-inch sapphire substrate prices were maintained at US $6.8-$7.2. Four-inch sapphire ingot prices also dropped to US $15-$16, while 4-inch sapphire substrate prices were about US $29-US $31. LEDinside, however, upheld a positive outlook for the sapphire industry performance in second half of 2014, pointing out a new wave of sapphire substrate orders could emerge if the iPhone 6 sales performance were good.

The sapphire material is still being applied in new generation Apple smartphones camera lenses and fingerprint recognition readers. If the iPhone 6 keeps up Apple’s previous smartphone models hot selling record, sapphire demands will be driven by the smartphone’s applications till the end of this year. However, the much anticipated sapphire cover glass remains missing from the picture. Analysis of the iPhone 6 supply chain indicates related component suppliers have to start shipping products to OEMs for assembly in June 2014 to meet the September launch date. Yet, the research institute did not discover demands for smartphone cover glass. The sapphire glass version iPhone 6 will be issued in limited volumes this year, mostly because sapphire ingot manufacturers yield rates were lower than forecasts and issues involved in sapphire glass processing.

Meanwhile, further observations will be required to determine whether Apple’s final iWatch will incorporate sapphire glass cover, said a LEDinside analyst, who declined to be identified. Since sapphire glass processing is relatively difficult, it would be problematic to mass produce sapphire watch cover glass if the iWatch is 2.5 D. Additionally, sapphire glass processing will become even more strenuous if the wearable device uses OLED panels.
