LiFi, or visible-light communication, has significant advantages over WiFi, such as data-transmission speed and the data security it offers because light does not penetrate walls. But wide adoption is constrained primarily because of interference between devices using LiFi networks and LiFi’s resulting poor performance in large areas. To solve this issue, researchers at CEA-Leti have designed a LiFi-multicell system which they believe is the first-ever smart interference orchestrator that automatically detects interference between lighting zones in networks and optimizes data transmi ..read more

Reviewing the 24 5G smartphones brought to market so far, Display Supply Chain Consultants (DSCC) observed that 20 of them or 83% are using an OLED. Why is the OLED adoption attach rate so high? The analysts ask, before offering some explanations. First, argues DSCC, because 5G smartphones are high-end phones, buyers are willing to spend more and expect the best display technology. Second, in China, the government is subsidizing the adoption of 5G by providing a subsidy of ~$100 to carriers and smartphone brands which makes it easier to afford the cost of a rigid or flexible OLED dis ..read more

Diodes Incorporated’s AL8843Q and AL8862Q automotive-compliant DC-DC buck converters are designed for driving single LEDs and multiple LED strings in and around vehicles. Applications include daytime running lights (DRL), which many manufacturers now offer as standard, as well as fog lights, turn lights, and brake/stop lights. With a supply voltage from 4.5V and to at least 40V (AL8862Q up to 55V), the AL8843Q and AL8862Q can withstand even severe voltage variations, such as load dumps during low cranking or stop-start operation, without suffering any corresponding degradation in th ..read more

The OptoArray launched by Optoscribe is a new range of precision fibre alignment structures, said to offer unrivalled levels of optical performance through the precise alignment of optical fibres. The OptoArray solutions can help reduce losses in optical circuits through the precise and stable alignment of fibres. This is particularly important given the demand for increasing levels of high density optical fibre in a wide variety of applications, including multi-fibre connectors, arrays for interfacing to optical switching hardware such as reconfigurable optical add drop multiplexers ..read more

Zytronic has developed a video wall demonstrator consisting of four multi-touch screens that are innovatively linked to enable seamless touch transition between screen tiles. Each of the four 55” multi-touch sensors in the 2x2 array features an ultra-narrow border, creating a sleek appearance by using the maximum display area. To build an interactive video wall, designers typically fix protective glass panels to each display and then use a clip-on infra-red or camera-based touch detection system around the tiled, narrow border screens, which creates an unsightly “protruding bezel ..read more

According to market research firm Yole Développement, the automotive lighting market is booming and expected to grow at a 4.9% CAGR between 2018 and 2024, from US$29 billion in 2018 to US$38.8 billion in 2024. “This growth is driven by natural LED cost erosion, coupled with standardization and optimization of LED modules, resulting in more vehicles equipped with this technology,” analyzes Martin Vallo, PhD. Technology & Market Analyst, Solid-State Lighting at Yole. “Today, automotive lighting is becoming one potential critical node for autonomous driving. Indeed lighting systems ..read more

On November 29, 2019, the Forum Groningen opened its doors. The new building includes a ten-story multifunctional meeting place, library, art cinema, an exhibition, restaurant, and study room for small groups. Also, it is one of the largest public buildings with tunable white luminaires throughout the entire space that can be dimmed to 0.1% and provide continuous dynamic adjustment of the light from 2500K to 4000K throughout the day. Using eldoLED drivers supporting the new DALI Device Type (DT) 8 standard and with integrated LightShape technology, precise control of the color and li ..read more

Telensa and LIGMAN announced that they have signed a partnership agreement to combine leading aesthetic LED luminaires and wireless controls. With energy and carbon reduction increasingly in the forefront of many cities’ agendas, switching lighting to LED is an obvious next step. Including wireless controls maximises the benefits of LEDs, generating further energy and maintenance cost-savings, and futureproofing further smart city sensing. “Cities across Asia Pacific are increasingly adopting wireless controls. Over the past couple of years Telensa has deployed smart street lighting ..read more

Rensselaer’s Lighting Research Center has partnered with Eaton Corporation on a project to develop a complete, additively manufactured, LED-integrated luminaire. Under funding from the United States Department of Energy, the project will address the main barriers to widespread adoption of additive manufacturing technology (also known as 3D printing) as applied to solid-state lighting. Over the next two years, the project partners will conduct material science, electronics, optics, and advanced manufacturing research to investigate the transformational potential of a fully additively ..read more

In an extensive digital signage installation project aboard cruise ship MSC Grandiosa, the latest and largest flagship of MSC Cruises, Samsung provided interactive touchscreens, digital signage and over 2,400 in-cabin TVs. The project’s crowning achievement is located at the ship’s indoor promenade, the central social hub of the ship, where a custom 93-meter Samsung curved LED IF040H-D display is installed on the ceiling. The display has been dynamically designed to create an awe-inspiring atmosphere at all times, and it showcases mesmerizing visual performances three times a day. “T ..read more
