vacuum-fluorescent display The term vacuum-fluorescent display is seldom hyphenated, but the first two words are hyphenated here as they constitute an adjectival phrase. The acronym VFD is be- coming increasingly popular, although it is ambiguous, being also used to identify a variable frequency drive. In both instances, the acronym is printed without periods be- tween […]

LED area lighting:What It Does,Trends in Cost and Efficiency,Schematic Symbol,How It Works,Visible Differences,Side-by-Side Comparison,Heat Dissipation,Efficacy,Dimming,Ultraviolet Output,Color Variation and Variants.
LED area lighting The term LED area lighting is used in this encyclopedia to describe a white LED source that is bright enough to illuminate rooms, offices, or outdoor areas. It may also be used in desk lamps or table lamps as task lighting. LEDs for these purposes may be categorized as high-brightness, high-power, high-output, […]

LED indicator:What It Does,Schematic Symbols,Common Usage,How It Works,Multicolor LEDs and Color Mixing,Diffusion,Wavelength and Color Temperature,Internal Resistor,Low-Current LEDs,Forward Voltage,Polarity,Series Resistor Value,LEDs in Parallel,Multiple Series LEDs and Internal Resistors.
LED indicator In this encyclopedia, an LED indicator is defined as a component usually 10mm or smaller in diameter, made of transparent or translucent epoxy or silicone, most often containing one light-emitting diode. It is purposed as a status indicator in a device, rather than as a source of illumination, and is sometimes referred to […]

laser:What It Does,How It Works,Laser Diode,Coherent Light,Variants,CO2 Lasers,Fiber Lasers,Common Applications,What Can Go Wrong,Risk of Injury,Inadequate Heat Sink,Uncontrolled Power Supply and Polarity.
laser The term maser was coined in the 1950s to describe a device that used stimulated emission to amplify microwaves. When a device using similar principles amplified visible light in 1960, it was termed an optical maser. However, that term is now obsolete, having been replaced with laser. This term is always printed in lowercase […]

fluorescent light:What It Does,How It Works,Ballast and Starter,Flicker,Variants,CCFLs,Sizes,Comparisons,Values,Brightness,Spectrum,Cannot Dim,Burned Out Electrodes and Ultraviolet Hazard.
luorescent light This entry deals primarily with fluorescent tubes (infrequently but sometimes described as fluorescent lamps), and compact fluorescent lamps (CFLs) that are marketed as a substitute for incandescent lamps. Cold-cathode fluorescent lamps (CCFLs) are also mentioned. Vacuum fluorescent devices have a separate entry in this encyclopedia. A fluorescent tube or CFL does not contain […]
