Behaviour of InGaN LEDs in Parallel Circuits
Some year s ago, the color range of Light Emitting Diodes ( L EDs) on the market was limited to the red to green spectrum. Then, blue LEDs were developed and introduced into the market . These blue devices made it possible to build so called “ single- chip white ” LEDs, using a yellow converter material in combination with a blue die. Most of the blue and white LEDs use Indium Gallium Nitrite (InGaN) as an epitaxial layer.
Driving laser diodes from CW to 155 MHz with power or current control
The all-purpose laser diode drivers iC-NZN and iC-NZP operate laser diodes in both CW and spike-free pulse mode with up to 155 MHz. The devices allow either the optical output power (APC) or laser diode current (ACC) to be controlled. In ACC mode also laser diodes without monitor diodes can be used. Blue laser diodes can also be operated with iC-NZN. The maximum available laser diode current is 300 mA. The devices have an adjustable current limit...

Less energy, more light quality in Kemerovo in Siberia
Kemerovo in Siberia is converting to street lighting with LEDs by OSRAM Opto Semiconductors on a broad scale. The city of 520,000 inhabitants on the Trans-Siberian Railway has installed 200 street luminaires made by LLC TD Focus, which are equipped with Golden DRAGON oval Plus LEDs. The city can therefore achieve significant savings in energy costs and CO2 emissions.
Vishay - IR Receivers Optimized for Extremely Noisy Environments and Short Burst Codes
Vishay announced that the company's optoelectronics portfolio now includes a complete family of miniaturized automatic gain control category 5 (AGC5) IR receivers for remote control systems. Vishay's AGC5 devices are suitable for codes with short bursts and offer excellent noise suppression, resulting in the best receiving distance under noise.
