Examine an LED bulb and you are likely to find the LEDs on board are phosphor-converted white LEDs (PC-LEDs). These are created either from blue- or near-ultraviolet-emitting chips emitting light at about 450 nm that are coated with a yellow phosphor. The phosphor down-converts the light output into lower visible light frequencies. PC-LEDs that operate […]
LED driver ICs optimized for instrument panel backlighting
Rohm announced the availability of the latest LED driver IC, the BD81A76EFV-M, optimized for LCD backlight in instrument cluster, center information displays and car navigation. Unlike conventional drivers with 4 channels that support LCDs up to 8”, this provides 6 channels of output (with 120mA per channel) that can support LCD panels of up to […]

The synchronous buck, buck-boost LED drivers/DC-DC converters offer a complete solution that features industry-leading EMI performance, without compromising on efficiency and size. These ICs drive up to eight HBLEDs […]
High-output surface-mount LEDs come equipped with a lens
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 […]
