Teardown: 60-W-equivalent LED bulbs
by LELAND TESCHLER, Executive Editor Surprise: A look inside five LED bulbs designed to replace 60-W incandescents reveals design regimes ranging from dead simple to startlingly sophisticated. The average consumer might think that when it comes to light bulbs, one is about the same as another. This view might have been accurate back when every […]
Vehicle designs get comfortable with LEDs
The trend for the past decade in the automotive industry has been toward vehicular lighting that’s all solid-state. Incandescent headlights are the last hold-out, and they are on their way to the junk yard of history. LEDs bring a number of well-chronicled advantages over traditional tungsten-filament incandescent light sources. Their improved luminous efficacy (lumens per […]
Powering LEDs for illumination
by Tony Armstrong, Linear Technology ICs that drive LEDs handle the complexities of illumination that include management of short circuits and squelching electrical noise. It’s no secret that LED lighting consumes much less energy than alternative forms of illumination and that the cost of LED lights is dropping fast. Consequently, the U.S. Dept. of Energy […]
Littelfuse Expands TVS Diode Array Line with New Series
Littelfuse, Inc. has introduced the SPxx-01WTG-C-HV Series (SPxx Series) of general purpose ESD Protection TVS Diode Arrays (SPA® Diodes). The SPxx Series extends previous improvements for protecting sensitive electronic devices from damage due to electrostatic discharge (ESD) and other overvoltage transients. These new “high-voltage” 0201-size components are well suited for safeguarding the data lines on […]
Driving LEDs with SiC MOSFETs
by ADAM BARKLEY, SiC Power Device Application Engineer, Wolfspeed, a Cree Company and VIPINDAS PALA, Research Scientist Wolfspeed, a Cree Company Engineers increasingly see the logic of silicon-carbide MOSFETs for handling a lot of electrical power, but new SiC devices also make sense for high-voltage switching. The benefits of silicon-carbide power MOSFETs are becoming widely […]
Light detection and amplification
A common sensor requirement is to measure light. This may be for adjusting the brightness of a display or for instrumentation where accuracy is of importance and light levels could be very low. The light could be relatively constant or slowly changing, or it could be modulated at high speed. There are a number of […]
Infineon digitizes power for energy-efficient LEDs
Every fifth kilowatt hour of electricity around the world is used for artificial light. LED technology, however, is making significant savings possible. About 13 million tons of CO 2 could be saved in Germany alone, equaling the emission of about seven million cars; in German office buildings, the electricity bill could be reduced by more […]
