Leland Teschler, Executive editor lteschler@wtwhmedia.com On Twitter @ DW_LeeTeschler A year ago, if your cocktail party conversations had included the idea of adding germicidal lights to a connected car, you probably would have elicited facial expressions suggesting you’d lost your mind. Today, the same idea would be more likely to engender a lot of head […]
LED drivers target automotive apps with wide programmable frequency operation, spread-spectrum clock
The TS19501 single-channel, dimmable LED driver targeting high-brightness automotive applications is well suited for virtually every automotive LED application: high and low beam headlights; daytime running lights; turn indicators; position indicator lights; fog lights; ATV and four-wheel drive high-brightness lamps. The IC is also offered in a version ideal for a wide range of non-automotive […]
It may become easier to disinfect with UV-C LEDs
UV radiation in the 200 to 300-nm range (dubbed the UV-C range) can destroy viruses, including the coronavirus. Problem is, doing so requires UV radiation sources putting out sufficiently high doses of UV light. That typically means using a relatively expensive mercury gas discharge lamp. It’s possible to find sources employing LEDs that put out […]
RECOM Power adds Sager Electronics as a distributor
RECOM Power, a manufacturer in power supplies specializing in AC/DC and DC/DC converters, switching regulators, and LED drivers, has revealed they have added Sager Electronics as one of its trusted distributors. Paul Kopp, Director, Supplier Marketing and Product Management for Sager Electronics states, “Renowned for developing and manufacturing the latest converter technology, RECOM Power boosts our […]
Surface-mount flip-chip back-emitting VCSEL array has no need for submount
TriLumina, developer of flip-chip VCSEL (vertical-cavity surface-emitting laser) technology for 3D sensing, announces the launch of the world’s first surface-mount flip-chip back-emitting VCSEL array without the need for a submount or bond wires, which allows for lower costs and higher performance than existing designs using near-infrared light-emitting laser diodes or LEDs for 3D sensing. Conventional […]
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 […]

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 […]
