Intelligent Back Light

EVT (Karlsruhe, Germany) has introduced a new industrial back light in its BrainLight smart illumination series. The LEDs of the intelligent back light can illuminate in the colors red, green, blue and white. There is a diffusor plate in front of the LEDs so that the light spreads evenly over the object. All together there are 48 full-color LEDs arranged in a tight grid. The BrainLight QC is 30 x 40 mm in size and has an input voltage of +24V. It is modularly expansible, meaning LED rows can be added, depending on application. The customer can choose any of the four available colors and the LEDs can be switched on row by row. Light sequences can be programmed and played successively. To learn more, click here.

Flexible Light Engine Material

Norlux (Elgin, IL) has introduced new NorFlex brand flexible continuous light engine material. The cuttable high-power LED circuits on a semi-rigid material provide 5x the lumen output of low power flex materials. Available on 200-400 ft. reels, the material is cuttable to maximize production flexibility. No special tools required! Most parameters are customizable – width, length, CCTs, LED spacing, power levels, custom components, etc. Both Constant-Current and Constant-Voltage versions are available. NorFlex circuits are designed to provide superior thermal performance, eliminating the need for big heat sinks. Suitable for fixtures with curved surfaces, low profiles or edge-lit.

60V LED Driver

Linear Technology’s (Milpitas, CA) LT3952 is a current mode step-up DC/DC converter with an internal 60V, 4A DMOS power switch. It is specifically designed to drive high power LEDs in multiple configurations. It combines input and output current regulation loops with output voltage regulation to operate as a flexible current/voltage source. Input voltage range is 3V to 42V. The LT3952 can drive up to sixteen 350mA white LEDs from a nominal 12V input, delivering in excess of 15 watts. It incorporates a high side current sense, enabling its use in boost mode, buck mode, buck-boost mode or SEPIC topologies. The LT3952 delivers efficiencies of over 94% in the boost topology, eliminating the need for external heat sinking. To learn more, click here.

Will robots hurt the job market?

This week's Question: In a cover article in this month's issue of The Harvard Business Review, two researchers suggest strategies for remaining gainfully employed in an age of robotics and smarter machines. Although the authors concede the advance of automation, editor at large Julia Kirby and Babson College professor Thomas H. Davenport write that machines will increase possibilities for employment and that “the threat of automation” could be reframed as an “opportunity for augmentation." The authors provide examples of opportunities for humans to collaborate with machines, including big-data drug discovery, precision agriculture, design work, and elder care. Machines and computers, however, already perform tasks formerly done by humans, including factory sorting, manufacturing, and even journalism. What do you think? Will robots hurt the job market?

The Sun’s Surface in Stunning Detail

Located on the Canary Island of La Palma, the Swedish 1-meter Solar Telescope (SST) is the world’s leading facility for high resolution observations of the Sun. It is operated by the Institute for Solar Physics (ISF), which is part of Stockholm University’s department for Astrophysics. Research at the institute primarily aims to gain knowledge about the outer layer of the solar atmosphere, which is dominated by magnetic fields. How do magnetic fields arise? How are they formed and ultimately destroyed or removed from the solar surface? How do they affect the Sun‘s outer atmosphere? How do they give rise to solar storms and the radiant energy that the Sun emits?
