30 Watt LED-Driver with high Design Lifetime and PFC
Long-life LED-systems only make sense if the driver does not fail prematurely. Our RACD30 have a higher life expectancy than most power LEDs. Efficiency and power factor set new trends in this product class.
New SynJet LED Cooler for Lumileds LUXEON S
Nuventix announced the availability of a new SynJet thermal management solution for the Philips Lumileds LUXEON S. The solution is based on the SynJet Par20 Cooler 24W, which combines the reliability, small size, and near-silent acoustics inherent with SynJet technology with a new mounting pattern for an easy plug-and-play solution for cooling spotlights and tracklights. The Par20 Cooler cools the LUXEON S in an ultra compact 66 mm diameter so...
Illumitex Announces Production of Artavi™ Precision LEDs with the Industry’s Narrowest Beam Angle and Fully-Integrated Optics
Illumitex Inc. have released today the lighting industry’s first and only precision beam LED for use in general, architectural and entertainment lighting applications, ranging from high mast street lights to stage and spot lights.
Dimmable 10W, AC-DC LED drivers meet harsh requirements for commerical outdoor lighting
Bias Power’s new 10 watt BPWXLD10 LED drivers offer 350mA constant current operation with 1% regulation over the entire input voltage range of 100-308VAC, 50/60Hz. LED string voltages up to 30VDC at 350mA or 14VDC at 700mA are supported. The drivers are dimmable and adjust output current based on either 0-10 VDC reference or ELV/Triac tracking. A constant-voltage version handles LED string voltages up to 12VDC. Either is compatible with dig...
ON Semiconductor Expands Portfolio of Constant Current Regulators for 1.0 watt LED Lighting Applications
ON Semiconductor has expanded its portfolio of Constant Current Regulators (CCRs) to include the NSI50350A. This simple and extremely robust device is designed to provide a thermally efficient and cost-effective alternative to passive/discrete components or driver integrated circuit (IC) solutions for current regulation of Light Emitting Diodes (LEDs). The device is ideal for a variety of 1 watt (W) lighting applications including automotive, arc...
STMicroelectronics’ Backlight Driver for High-Tech Handhelds Saves Power, Time and Money - Miniature control IC for energy-efficient white-LED backlights simplifies circuit design
STMicroelectronics has extended its portfolio of energy-saving solutions for mobile devices with a new IC that simplifies the design of power-efficient LCD and keypad backlights comprising white LEDs. Backlights built with white LEDs, instead of traditional fluorescent tubes, consume less power enabling longer battery life for portable devices such as smartphones, games and GPS terminals.

Flexible LED-UV curing - Flood or Spot
The new DYMAX BlueWave LED DX-1000 is a unique and flexible 385 nm LED curing system that can be configured to operate as either a small-area flood or spot-cure system. In flood mode, up to 1 W/cm2 can be delivered over a 1” x 1” (2.5cm x 2.5cm) area. In spot mode, a single or multi-pole lightguide can be installed into an optional adapter to deliver up to 15 W/cm2 in a high-intensity spot.
Laboratory record: red LED breaks through the 200 lm/W barrier
A red high-power LED has set a new efficiency record in an OSRAM Opto Semiconductors R&D lab with an electro-optical efficiency of 61%. The 1 mm2 chip housed on a laboratory package emits at a wavelength of 609 nm (λ-dom) and has achieved a record value of 201 lm/W at an operating current of 40 mA. At a typical operating current of 350 mA its luminous efficacy is still an impressive 168 lm/W, which means that even at this high wattage more t...
