Understand thermal characterization of high-power LEDs for reliable SSL

Die attach materials used in the assembly of LEDs directly influence device operating temperatures, and of course we know that heat is the enemy of reliable LED components and finished solid-state lighting (SSL) products. Higher thermally conductive materials, such as sintered nano-silver, allow an LED to operate at lower temperatures. This impact leads to higher […]


Quantum Dot Based White LEDs for General Illumination

Colloidal quantum dot based white LEDs can be integrated into commercial products meeting the stringent reliability requirements for general illumination and providing LED efficiency gains of 5% to 15% over commercial phosphor based LEDs at CCT’s ranging from 5000 K to 2700 K. Unlike earlier demonstrations, the QD material is applied in an on-chip configuration […]


Eviyos LED Prototype Revolutionizes Smart Headlights

The Eviyos prototype developed by Osram Opto Semiconductors is the world’s first hybrid LED and represents major progress toward the first market-ready smart controllable high-resolution LED. As soon as oncoming traffic is detected the appropriate pixels are automatically switched off so drivers of oncoming vehicles are not dazzled. The prototype, integrated in a demonstrator from […]


IoT lighting into clothing

Working with Fürth, Germany-based safety and sportswear company uvex, Osram is stitching LEDs into safety vests and work jackets. Osram’s first stab at textile illumination stops short of interactivity. It simply focuses on giving visibility to workers on job sites. “The textile illumination is incorporated into the safety clothing and ensures greater visibility and hence […]


Seoul announces horticultural LEDs; Cree, Lumileds, and Osram show recent newcomers

Seoul horticultural entry The Seoul announcement became what was perhaps the broadest horticultural LED launch in the industry, even surpassing the Lumileds SunPlus announcement last year in breadth. Seoul is the only vendor offering horticultural-centric products spanning the UV range to the near infrared (NIR) bands. Moreover, the company is targeting some LEDs at horticulture […]


Three New Color-Tuning Modules for Lighting Design

MidiMax CTM Bluetooth, Edison Price Lighting • This color control functionality is available in the company’s wallwashers and tracklighting luminaires that use the Lumenetix Araya LED module through the Bluetooth-operated Araya Tunable Color 2.0 smartphone application, which can control dimming, power, hue, and saturation. The module allows for a correlated color temperature (CCT) range of 1650K […]


Bluetooth Mesh Shows Wireless Connectivity in a Whole New Light

Wired lighting infrastructures have a history of providing dependability that, until recently, wireless networks couldn’t match. And while there are other benefits to installing a wired network, many of today’s wireless platforms—especially those supported by a Bluetooth® mesh network—ensure greater flexibility and extensibility at a reduced cost. Wired vs Wireless Advancements in wireless connectivity make it hard […]


SD-WANs growing rapidly

Software-defined wide area networks have only been commercially available for a few years but, according to IDC, worldwide SD-WAN infrastructure and services revenues will see a CAGR of 69.6% and reach $8.05 billion in 2021. The most significant driver of SD-WAN growth over the next five years will be digital transformation (DX) in which enterprises […]
