Product of the Month: July 2015

ZF Electronics Corp., Pleasant Prairie, WI, announced CHERRY energy-harvesting products that include an energy harvesting generator, as well as a snap-action micro-switch and rocker switch. The energy-harvesting generator is able to generate its own power, store the power in a chip, and transmit a signal via RF technology without the use of wires or batteries. The generator can be housed in a standard CHERRY switch product or a custom assembly. The AFIS wireless snap switch and momentary rocker switch provide data transfer via RF technology, eliminating the need for complex wire assemblies, and enabling use in inaccessible locations. The required energy is generated by mechanical actuation of the switch, eliminating the need for batteries. Flexible pairing allows operation of several switches with one receiver and vice-versa, and the switch “Unique ID” provides clear identification while operating several switches at once.

NASA Releases Global Climate Change Projections

NASA has released data showing how temperature and rainfall patterns worldwide may change through the year 2100 because of growing concentrations of greenhouse gases in Earth’s atmosphere. The data shows projected changes worldwide on a regional level in response to different scenarios of increasing carbon dioxide simulated by 21 climate models.

RoboSimian Drives, Walks, and Drills

The ape-like RoboSimian robot, developed at NASA’s Jet Propulsion Laboratory, took fifth place in the DARPA Robotics Challenge (DRC) Finals. RoboSimian squared off against 22 other robots in the international robotics competition, which promoted the development of robots that could respond to disaster scenarios too dangerous for humans.

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.
