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 […]

How to design a functionally safe vehicle display
It pays to know about the ASIL B compliance measures needed for automotive subsystems. Szukang Hsien, Automotive Business Unit, Maxim Integrated TAKE the wheel of a new car today and you’ll be greeted with the bright glow of screens filled with useful data: how fast you’re going, what’s playing on the radio, a playlist of […]
Three-channel automotive LED controller uses external MOSFET for better thermal dissipation
Texas Instruments introduced the first 3-channel high-side linear automotive light-emitting diode (LED) controller without internal MOSFETs which gives designers greater flexibility for their lighting designs. The TPS92830-Q1’s novel architecture enables higher power and better thermal dissipation than conventional LED controllers, and are particularly beneficial for automotive LED lighting applications that require high performance and reliability. […]
Natural-spectrum LEDs get RG-1 Eye Safety certification
Seoul Semiconductor announced that SunLike Series LEDs, which implement light that closely matches the spectrum of natural sunlight, received an RG-1 Eye Safety certification based on the safety of its light source and was recognized for the highest level of safety among 25W COB type LED. Eye Safety certification is a rating based on safety […]
Compact LED drivers put out 24 W with 20 W/in.3 power density
Seoul Semiconductor has developed an ultra-compact LED driver series with a power density 5X higher than conventional LED drivers. Based on Seoul Semiconductor’s patented Acrich technology, the MicroDriver Series delivers more than 24W of output power with a power density of 20W/cubic inch cubic inch, compared to existing drivers at 3-5W/cubic inch. Measuring just 1.5” […]
Horticultural LEDs cover UV-C to Far-Red light spectrum
A new family of Horticultural Series LEDs in COB in mid-power, and high-power packages, also includes Seoul Semiconductor’s SunLike Series natural spectrum LEDs, which produce light that closely matches the spectrum of natural sunlight. Seoul introduced the new Horticultural Series LEDs at the 2017 Horticultural Lighting Conference in Denver, CO, on October 17. One of the […]
N-channel power MOSFETs target automotive load switching in LED drivers
The expanded of automotive N-channel power MOSFETs from Toshiba includes the 60V SSM3K341R and the 100V SSM3K361R. Housed in small SOT-23F packages, the new MOSFETs feature low on-resistance and are suited to load switching in LED driver applications, including automotive dashboard meters and headlights and LED TV backlights. Increasing demand for power-saving LEDs has led to […]
