STMicroelectronics Introduces World's First Universal Lighting Controller
(Thomson Reuters ONE) -
Industry-unique device opens the way towards cost-effective, energy-efficient
lighting systems in the home, in the office, and on the street
Geneva, February 11, 2013 - Domestic, commercial and public lighting systems can
now be made greener, more economical, safer and more flexible, thanks to a
unique device introduced by STMicroelectronics (NYSE: STM), a global
semiconductor leader serving customers across the spectrum of electronics
applications and a world leader in power-management solutions. The world's first
programmable digital controller specifically optimized for lighting and power-
supply applications, the new STLUX385 (Masterlux(TM) platform) simplifies the
design of traditional power-conversion topologies, enabling faster development
of innovative lighting systems.
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 proven, cost-effective 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. Depending on factors such as the
lighting technology used, the input power source (AC or DC), dimming
requirements and safety or reliability issues, many different types of power
conversion and control topologies are required in the current and emerging
lighting applications and the STLUX385 is the first device able to address all
of these via a single programmable chip.
"More than 20% 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 achieves this goal primarily by integrating six specially-designed
peripherals called SMED (State Machine, Event-Driven) circuits that interact
with each other and with external signals via a programmable switching matrix to
control the power delivered to the lighting elements. In addition to the
specific application signals, the SMEDs can process external commands to turn
the lights on/off or set the dimming level, diagnostic signals such as open- or
short-circuit detected, or inputs from sensors in applications where the
lighting is designed to adapt to ambient conditions.
For example, this 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 STLUX385 allows sophisticated lighting systems that currently require the
use of expensive external Digital Signal Processors to be produced with shorter
time-to-market and lower costs. It allows light quality and its perception to be
improved through dedicated algorithms and energy saving through high-efficiency
conversion algorithms, while allowing new interactions between the user and the
lighting system.
In addition to the six SMED peripherals, the STLUX385 also integrates a hardware
DALI (Digital Addressable Lighting Interface) peripheral. Digitally controlled
lighting is the key to energy saving in building and outdoor lighting
installations and the DALI protocol is now in international use across the
lighting industry. The STLUX385 is compatible with wired or wireless
communications, simplifying the installation in large indoor and outdoor areas
and reducing maintenance costs.
The STLUX385 is available now in a compact TSSOP38 package at a price of US$2 in
quantities of 1,000 units.
