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.

In recent years, the need to improve both design quality […]
High-voltage LED-lighting control chip meets latest demands for efficient dimming
STMicroelectronics has combined its-control expertise with advanced power technologies in a new all-in-one LED control chip that enables future luminaires to save more energy and deliver better user experiences. The HVLED001B controller simplifies designing LED-lighting modules, maximizes energy efficiency at all dimming levels, and ensures smoother brightness control. Lighting innovator TCI of Italy, a lead customer, has […]
Don’t get burned about LED UV
Another myth busted: You needn’t worry about ultraviolet light coming from ordinary LED bulbs. We recently checked a batch of LED bulbs for the amount of blue light they gave off. This effort came in response to claims from some in the alternative medicine crowd that LED bulbs gave off inordinate amounts of unhealthy blue […]

Designed for both indoor and outdoor general lighting applications, the OSLON Square LEDs feature an ultra-compact 3mm x 3mm (3030) package, with a range of color temperatures (CCT) […]
Don’t let the LED blue light blues get you down
Despite claims by some websites to the contrary, LED bulbs don’t put out inordinate amounts of blue light. Leland Teschler, Executive Editor Take a look at some of the websites devoted to alternative medicine and you’ll likely come across headlines like, “The Dangers of LED & Blue Lights Will Blow Your Mind!” or, “LEDs: The […]
New IC handles LED matrices with high efficiency
Designers of high-performance automotive matrix lighting and adaptive driving beam light-emitting diode (LED) applications can now migrate to higher current devices while reducing solution size and improving flexibility with the MAX20092 12-switch matrix manager from Maxim Integrated Products, Inc. The IC minimizes thermal issues associated with LED matrix lighting applications by offering the industry’s lowest internal switch […]
