LUXEON UV U1 Doubles Performance Of Current Smallest UV Emitter In The Industry

The LUXEON UV U1 delivers twice the irradiance power of the previous generation UV LED at 380-390 nm in a miniature 2.2 mm2 SMD package with a 5x greater power density.

Leveraging its leading expertise in chip scale packaging, Lumileds today introduced the LUXEON UV U1 LED for use in UV curing, counterfeit detection, analytical instrumentation, inspections and other UVA and Violet (380-420 nm) applications. This third generation of UV LEDs maintains the same micro package size as LUXEON Z UV, but enables a higher power density. LUXEON UV U1 also features a robust design that eliminates materials like silicone over mold, which tends to yellow and crack upon UV exposure, and the elimination of wire bonds that can lead to catastrophic connection failures. “UV LED customers are reliability driven. They tend to run their equipment 24/7 and demand a proven product that will perform as expected for over 20,000 hours. The LUXEON UV U1 is that reliable product,” said Yan Chai, Product Line Director of Lumileds UV LEDs.

Lumileds Introduces LEDs That Best Accentuate The Freshness Of Fruit And Vegetables With FreshFocus Technology™, Part Of The LUXEON Stylist Series

LEDs with FreshFocus Technology gives produce its freshest, just-picked appearance.

Lumileds today revealed its FreshFocus Technology for produce, LEDs to showcase fruit and vegetables in their freshest and most appealing state. FreshFocus Technology is part of the LUXEON Stylist Series, Lumileds transformative line of LEDs designed to provide the perfect lighting environment to sell products in fashion retail stores, fresh food markets and restaurants.

“Shoppers really buy with their eyes. When you optimize the saturation of the most dominant colors in produce, they appear fresher and more appetizing, leading to higher sales,” said Luis Aceña, Senior Manager, Stylist Series at Lumileds. Typical return on investment for LEDs with FreshFocus Technology is within one year. “LED lighting is so attractive already to supermarkets because of the significant energy savings,” said Aceña. “Now we can help grocers boost sales by making produce as appealing as possible, providing further incentive for market differentiation.”

60V Synchronous Buck Battery Charger Includes Lead-Acid & Li-Ion Charge Algorithms for up to 20A Charge Current

Linear Technology Corporation introduces the LTC4013, a highly integrated, high voltage multi-chemistry synchronous step-down battery charger controller. With a wide input voltage range that spans up to 60V, the LTC4013 uses temperature-compensated 3- and 4-stage charge algorithms to efficiently charge 12V and 24V lead-acid batteries. Alternatively, the LTC4013 will charge a multicell Lithium-based battery stack with float voltages near to the input supply. Mode pins define the float voltage and charge algorithm. Charge current is precision regulated to ±5% and programmable with a single resistor up to 20A (depending on the selection of external components). The LTC4013 features user-adjustable maximum power point tracking (MPPT) circuitry that enables simple power optimization in the case of power-limited sources such as solar panels. The MPPT open-circuit method corrects for panel temperature changes without the inconvenience of adding a solar panel temperature sensor. Applications include portable medical instruments, monitoring equipment, battery backup systems, industrial handhelds, industrial lighting, military equipment, ruggedized notebooks/tablet computers, plus remote powered communication and telemetry systems.

New Cree® MHB-B LED Lowers System Costs for High Performance Lighting Applications

Cree, Inc. (Nasdaq: CREE) introduces the XLamp® MHB-B LED, a new high-power LED that enables a more effective way to deliver lower system costs for high lumen, high-efficiency applications designed to meet the new DesignLights Consortium® (DLC) 4.0 Premium requirements. Leveraging key elements of Cree’s SC5 Technology™ Platform, the ceramic MHB-B LEDs combine high light output, high efficacy and high reliability to enable high lumen LED designs that are not possible with mid-power LEDs. The MHB-B LED delivers up to 931 lumens at 85°C and 13 percent higher LPW than the MHB-A LED in the same 5mm x 5mm package, allowing lighting manufacturers to increase quickly performance for existing MHB designs without any additional investment.

3 Steps Electrical Engineers Should Take to Obtain the Best Electronic BoM Costs

To stay competitive in today’s extremely tough markets, electrical engineers have to not only be technically adept at designing in components that give their products a competitive edge, but they also have to know the best practices in assuring that the Bill of Material (BoM) costs are as low as possible.  As the electronic component BoM cost usually represents the single largest cost element of an end-product, being good at controlling these costs can give companies in saturated markets a competitive edge. 

The field applications engineers at SemiElectronics have come up with the 3 top items that engineers should pay attention to during design process and beyond to leverage the best BoM costs possible.

TRIAC-Dimmable LYTSwitch-7 LED Driver ICs From Power Integrations Cut BOM Count by 40%

Bleeder-less, highly efficient, robust IC family serves bulbs, tubes and fixtures up to 22 W

Power Integrations (Nasdaq:POWI), the leader in high-efficiency, high-reliability LED driver ICs, today announced its LYTSwitch™-7 single-stage, non-isolated, TRIAC-dimmable, buck topology LED driver IC family. Capable of delivering up to 22 watts without a heatsink in a very small SO-8 footprint, these high-efficiency devices are suitable for bulbs, tubes and fixtures. LYTSwitch-7 designs do not require bleeders; employing simple, passive damping for TRIAC management and an off-the-shelf, single-winding inductor, reducing component count to just 20, as compared to approximately 35 parts for typical dimmable LED driver boards.

International Standards Organizations Governing Electronic Products

With thousands of international standards organizations across the world, may aspects of life is subject to standardization, which is a good thing for most people.  Standardizing various processes and systems helps make life safer and even more productive.  The electronics industry, in particular, is subject to thousands of global standards, and hundreds of individual regulatory bodies that create, endorse, and support these standards.

As an electrical engineer working on electronic designs, it’s important to know about some of the international standards organizations that govern electronic products.  Here are some of the well-known organizations that we find engineers work with most frequently:

Z-Wave - Popular Wireless Protocol for Home Automation and Internet of Things Devices stars

As Internet of Things (IoT) becomes the new frontier in technology, all attention seems to be turning to wireless networks for home automation. One of the key players in remote home security and automation is without a doubt the Z-Wave protocol.

Z-Wave, also known as Zwave, is a communication protocol that uses RF signaling to connect and control devices used in home automation. It is a low bandwidth protocol, capable of sending short messages reliably, from one control unit to several slave nodes connected in a network. Z-Wave protocol is made of four layers:
