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 […]
Programmable 12-channel RGB-LED driver enhances lighting effects for smart devices and wearables
With patented features to prevent distracting artifacts in “color-chasing” or “deep breathing” LED animation effects, the STMicroelectronics LED1202 12-channel LED driver enables smoother and more natural interactions with smart-home devices, wearable electronics, and small appliances. The LED1202 can store eight programmable patterns and sequences and operate independently of the main controller, enabling the host system to save […]
60V fast dimming controller targets automotive LED lighting
Diodes, Inc announced the availability of the AL5816Q, an automotive-compliant linear LED controller for automotive LED lighting. With an operating voltage range of 4.5V to 60V, the AL5816Q supplies an output drive current of 15mA to control LED lights through an external BJT, delivering a constant current of a few mA up to 1.5A, or […]
UV-C LEDs are non-chemical solution to sterilization and disinfection
CEL today announced a new family of Deep UltraViolet (UV-C) LEDs for a wide range of sterilization and disinfection applications including consumer goods such as self-disinfecting holders for toothbrushes and kitchen utensils as well as sterilizing wands for items such as smartphones, tablets and keyboards. Other applications include water treatment, sterilization of medical equipment and […]
60-V linear LED controller ICs optimized for general lighting apps
With the BCR601 and BCR602 Infineon Technologies AG introduces two new members of its BCR linear LED controller IC portfolio. The BCR601 features innovative voltage feedback to the primary side also known as “active headroom control” (AHC), enabling cost- and power-effective LED driver applications. The BCR602, on the other hand, targets dimmable LED applications such as light engines, […]
Water-resistant LED lighting drivers deliver 160 to 600 W
Brightworks Technology, Inc. announces its new development initiative to produce reliable, efficient, compact and water-resistant AC/DC LED drivers for demanding outdoor, architectural lighting, signage, and horticulture applications. After more than a year of market research and industry feedback, the first product line from the new initiative is the Silverback series of LED drivers, which will be available […]
LED bulbs then and now: Teardown of the EcoSmart, Feit, and Sylvania 60-W equivalent LED bulbs
Compared to the LED bulbs of only a few years ago, modern-day versions are simpler and assembled via more automated methods. Leland Teschler, Executive Editor If you tore down an LED bulb manufactured a few years ago you’d likely find evidence of hand soldering a bit of kludgy design practices. We found both these practices […]
White-chip LEDs in 1608 packages feature high reliability
ROHM today announced the availability of the SMLD12WBN1W, a White chip LED with 1608 (1.6×0.8mm) size that achieves class-leading reliability. This new package offers superior mountability and long operational life, which makes it ideal for use in display panels (e.g. temperature control displays) in industrial and compact consumer equipment. In recent years, the need to improve both design quality […]
