LEDs, with their high performance and long service life, are growing exponentially in popularity. This tendency is even enhanced by the increasing efficiency and falling prices. However, to make the best possible use of all the benefits offered by LEDs, effective thermal management is indispensable.

Dialight today announced the availability of its new Vigilant L-864 Infrared (IR) LED-based Medium Intensity Red Beacon, the first FAA-certified product of its kind, incorporating both red and IR LEDs in a single unit. The IR integration ensures better visibility for aircraft pilots using Night Vision Goggles (NVGs) and Aviator’s Night Vision Imaging Systems (ANVIS) for improved safety near military bases and airfield perimeters within the most...

Its recent upgrade to Dialight high-efficiency LED High and Low Bay fixtures has enabled the City of London Corporation to slash energy use by approximately 70 percent, reduce total fixture count by one-half and virtually eliminate lighting maintenance, all while significantly improving visibility and overall operational efficiency at its quad-level Walbrook Wharf. With a change-out that took less than five minutes per fixture, the Corporation ex...

NXP today announced the SSL2115x series of high-efficiency GreenChip driver ICs for low-cost LED retrofit lamps. The new SSL21151 and SSL21153 are designed for non-dimmable 5W and 10W LED lamps respectively, providing good current control in flyback and buck-boost configurations. The SSL2115x enables small form-factor LED drivers, using primary-side sensing to regulate current, and offering integrated LED open/short protections, an internal 700V ...

OMC has introduced a range of Light Engines designed to simplify LED lighting design. SPECTRALUX light engines enable luminaire manufacturers and other lighting users to produce a vast range of products that deliver excellent illumination and have an extremely long life time at particularly high luminous efficiencies which in many cases exceed 100lm/W.

OMC can now offer bespoke backlights for LCDs based on a new emitter design that provides the brightness of a dual chip emitter but requires only the forward voltage of single chip solution. Therefore, for the first time, users can drive OMC’s white and blue Profiled Backlight range from a 5V source, which OMC say is becoming ever more desirable in modern applications.

GlacialLight has today announced the GL-BL220-CW LED Bay Light with Philips Lumileds chips and patented wide heat dissipation for longer life. The GL-BL220-CW floods large spaces with bright natural light, but has low energy consumption and maintenance costs.

VCC has recently purchased the complete Chicago Miniature indication and illumination product lines, as well as their related patents and intellectual property, from Chicago Miniature Lighting, LLC, which is located in Novi, Michigan. With thousands of unique LED, incandescent, and neon indicators and broad international distribution, VCC is now the largest provider of indicators globally.

Standard LED drivers (buck topology) require the input voltage be higher than the output voltage which can cause problems when working with the newest high power LEDs and powering them from low voltage sources like solar cells or batteries. Buck driver solutions, which must always have a higher input voltage than an output voltage, typically result in a design that requires multiple drivers for multiple led strings with lower forward voltages. Th...

Yole Développement and EPIC announce their report dedicated to the LED industry: “Status of the LED Industry”. The report presents all applications of LEDs and associated market metrics, LED cost reduction opportunities, entire LED value chain, a deep analysis of the general lighting application and an analysis of geographical trends.
