ROHM today announced the availability of compact high output surface mount LEDs equipped with lens. This new lineup includes 18 devices, comprised of the CSL0901 series featuring standard brightness and the high brightness CSL0902 series. Recently, most vehicle instrument cluster designs have adopted shields to prevent light leakage from the LEDs to surrounding areas. However, light leakage remains a challenge […]
Dimming is a bright spot for new 80-V DC-DC buck LED driver IC
Infineon Technologies AG introduces the new LED driver IC ILD8150/E. It features an innovative hybrid dimming mode technology for achieving 0.5 percent of the target current. With its supply voltage range from 8 V DC up to 80 V DC, the driver IC provides a high safety voltage margin for applications operating close to safe extra-low voltage (SELV) […]
How LiFi and LEDs will combine to brighten our future
by Paul Golata, Mouser Electronics Gone are the days when lights were standalone devices whose sole purpose was to illuminate a particular area. The rise of connectivity and data-dependency in our lives means the role of luminaires is changing. Connected lighting systems (CLSs), using light-emitting diode (LED) technology and Internet of Things (IoT) connectivity, now […]

Eight-port PoE switch provides 60 W per port
The adoption of commercial smart lighting systems has grown significantly as organizations strive to improve energy efficiency and operational costs in buildings. Power over Ethernet (PoE) is rising in popularity for these systems, providing a reliable and easy-to-install solution that manages power and data over a single Ethernet cable. To support larger and more efficient […]
RGB LEDs target accent/decorative lighting, optical displays, industrial apps
Würth Elektronik announced the WL-SFTW and WL-SFTD series of new RGB LEDs that are ideal for accent and decorative lighting, optical displays as well as industrial applications. Thanks to their PLCC contacting design, the two series of individually controllable LEDs are ideally suited for SMT assembly and reflow soldering. The WL-SFTW series offers three different […]
Single-stage, high power factor LED driver-controller incorporates mixed-mode dimming
Diodes Incorporated announced the introduction of the AL1665 single-stage, fly-back and buck-boost controller for commercial, connected, and dimmable LED lighting installations operating at up to 100W. The AL1665 is designed to drive an external MOSFET to control LED loads and maintain a high power factor. It provides a compact and efficient solution that helps minimize […]
Achtung! Power technology on display at PCIM Nuremberg
PCIM Europe is billed as the world’s leading exhibition and conference for power electronics, intelligent motion, renewable energy, and energy management. Recently wrapping up in Nuremberg, the exhibition portion of PCIM featured over 500 booths. Here are some of the more notable technology displays we saw in touring the event. NEXT PAGE: Smaller inverters for […]
Boost controller delivers 100:1 dimming ratio
Diodes Incorporated introduced the AL3353 LED/LCD 40V max input boost controller, applicable across a wide range of applications where a constant voltage or constant current are required to drive displays and backlights with a dimming ratio of 100:1. It is well suited for use as a backlight driver for LCD TVs, LCD monitors, and flat panel […]
Teardown: Simple approach characterizes modern LED bulbs
LED bulbs we examined are often simpler than those made four years ago, sometimes employing discrete transistors to handle tasks once done via chips. Leland Teschler, Executive Editor Back in 2015, we examined LED bulbs putting out the equivalent of 60-W incandescent bulbs. We recently obtained several new LED bulbs to see how things have […]
