1550 nm pulsed laser diodes (PLDs) are integrated into rangefinder systems, etc. Standard night-vision goggles cannot detect this wavelength. Thus, these PLDs are particularly useful in military laser rangefinders or in friend/foe recognition.

Leading the industry with technological innovation and the latest Organic LED advancements, WAC Lighting has received two Product Innovation Awards from Architectural SSL Magazine, for Sōl™, its Organic LED Chandelier. WAC Lighting is a global manufacturer and designer of track, recessed, undercabinet, monorail and decorative lighting. The WAC Sōl™ Chandelier received a Special Citation for the best use of OLED (organic light e...

Although the development of LED lighting technology, especially with regard to efficacy and the production costs of semiconductors, has not yet been maximized, there is already a new technology standing at the ready: organic light emitting diodes (OLEDs) – a technology that uses organic materials for illumination.

The new infrared Mini Midled from Osram Opto Semiconductors is only 0.9 millimeters high, but this tiny device produces a narrow and intense beam of infrared light that provides the highest radiant intensity of its size class. With a radiant intensity of 60 milliwatts per steradian (mW/sr) at 100 milliamperes (mA), it easily outperforms other comparable devices. This low-profile, surface-mountable emitter is ideal for proximity sensors and light ...

Diodes Inc. have announced the release of the AL5801 linear LED driver. Needing only two additional components, the AL5801 linear LED driver enables designers to simplify automotive interior, signage and general lighting control circuits. Integrating a 100V rated N-channel MOSFET with a pre-biased NPN transistor, this small footprint SOT26 packaged device will drive chains of up to 30 low-power, series-connected LEDs with currents from 20mA to 3...

The TopLED Black Series with lens from OSRAM Opto Semiconductors is a range of medium-power LEDs mounted in an industry standard package but in matte black material. The black package offers significantly higher contrast with lower reflectivity than comparable white-package devices without compromising overall luminous intensity. The TopLED Black Series is ideal for display applications where contrast is key for improved legibility, especially in...

Photonic Products Ltd, authorised distributor of SANYO laser diodes, has announced that, due to the recent merger between SANYO and Panasonic, SANYO will end production of its industrial red and infrared laser diodes at the end of September 30th 2010. The last time buy date for all affected product lines will be March 31st 2010.

The inexpensive LSC-035 driver was developed for N type cw laser diodes with a maximum operating current of 300mA. The wide-ranging supply voltage of up to 15V allows the operation of blue, red, and NIR laser diodes.

Oclaro, Inc. has announced that it has further strengthened two of its leading high-power laser diode product families by delivering next generation parts that feature improved performance, reliability and industry-leading cost competitiveness. The new parts are ideal for DPSS pumping and direct diode applications and include 60W at 880nm as well as 120W at 910 to 1070nm, both on a passive cooler.

Although it is relatively straightforward to design a basic LED driver for a general lighting application, it becomes far more complex when additional functionality such as phase cut dimming and power factor correction are also required. A non-dimming LED driver with no power factor correction generally consists of an off line switching power supply configured to regulate the output at a constant current. This is not much different from a standar...
