STMicroelectronics introduces world’s first universal lighting controller

Unique device opens the way towards cost-effective, energy-efficient lighting systems in the home, in the office, and on the street

STMicroelectronics has developed a unique device which is the world's first programmable digital controller specifically optimised for lighting and power-supply applications, the semiconductor company announced on Wednesday (13 February).

The new STLUX385 (Masterlux platform) simplifies the design of traditional power-conversion topologies, enabling faster development of innovative lighting systems.

This device can make domestic, commercial and public lighting systems greener, more economical, safer and more flexible, claimed the manufacturer of this device.

For example, this innovation opens the way towards intelligent LED street lamps that increase their brightness gradually as daylight fades and, conversely, automatically reduce their brightness as the sun rises instead of having only a full brightness or off-setting at predetermined times.

The key to the new possibilities for improving the performance of LED, fluorescent and HID (High-Intensity Discharge) lighting systems is the STLUX385's combination of a STM8 microprocessor core and a unique set of peripherals aimed at simplifying the design of the lighting power supply and digital control of the lights, the company said in a statement.

"More than 20 percent of the electricity generated is used to light our homes, streets, offices, factories and public areas, and making lighting more efficient is an essential step on the path towards a sustainable world," said Matteo Lo Presti, STMicroelectronics Group Vice President, Industrial & Power Conversion Division. "The STLUX385 distils 25 years of ST leadership in power conversion solutions into a single high value platform that customers can use to build more innovative and efficient lighting solutions."

The STLUX385 is available now in a compact TSSOP38 package at a price of US$2 in quantities of 1,000 units.
