Constant-current LED drivers suitable for edge lighting
As a result of growing demand for smaller LED lighting installations that also provide high efficiency and ultra-low EMI, Diodes Incorporated has extended its BCR420U and BCR421U families of linear LED drivers to include the BCR420UFD and BCR421UFD devices in the ultra-low profile DFN2020 package, making them suitable for 12 and 24V LED edge-lighting applications.
Minnesota celebrates the big game with LED light show
Philips Lighting will feature a series of dynamic light shows on the I-35W Saint Anthony Falls Bridge on 2nd-4th February 2018, in celebration of this Sunday's Super Bowl taking place at the US Bank Stadium in Minneapolis between the New England Patriots and the Philadelphia Eagles.
SPD module designed for outdoor LED lighting protection
The LSP10GIHP series modules provide coordinated protection for most commercially available LED drivers used today, reducing driver failure more effectively than ever before. Lower clamping voltage and surge let-through current ensure greater luminaire protection.
Meet the founder: Interview with a 'lighting guru'
When you’re designing a commercial or residential space, lighting might be the last thing on your mind. However, it can have a profound effect, on the people living or working there and, for businesses, on the potential customers coming through your door. And the lighting industry is just as ripe for innovation as any other sector. Breakthrough Magazine asked Bruce Weil, Director of Lighting Design Studio, about his light bulb moments.
Boost efficiency and stability of optical rectennas
The research team that announced the first optical rectenna in 2015 is now reporting a two-fold efficiency improvement in the devices — and a switch to air-stable diode materials. The improvements could allow the rectennas – which convert electromagnetic fields at optical frequencies directly to electrical current – to operate low-power devices such as temperature sensors.
Science imitates art: Star Wars-inspired 3D images
In the original Star Wars film, R2D2 projects an image of Princess Leia in distress. The iconic scene includes the line still famous 40 years later: “Help me Obi Wan Kenobi, you’re my only hope.” BYU electrical and computer engineering professor and holography expert Daniel Smalley has long had a goal to create the same type of 3D image projection. In a paper published in Nature, Smalley details the method he has devel...
Thermal camera combines accuracy and sensitivity
Including a thermal sensitivity function which is twice as precise that of the industry standard, the FLIR T1030sc combines an extraordinarily sensitive detector with High Definition (HD)-ready optics, the camera detects temperature differences of less than 20mK at 30°C.
MicroLED-based AR and VR HUD concept displayed at CES 2018
Plessey Semiconductors has successfully demonstrated how its monolithic microLED technology can be used to deliver the next-gen of Head-Up Displays (HUDs), enabling new AR and VR applications. MicroLEDs are emerging as the only technology that can provide high luminance in a small format. All leading manufacturers of wearable technologies are currently pursuing manufactures that can deliver a suitable microLED solution.
