Light sources are
devices whose primary function is to produce visible or near-visible
radiant energy for general illumination and specialty applications. They
include incandescent, fluorescent, and high-intensity discharge (HID)
lamps, as well as solid-state lighting (SSL) that may be pin- or
SSL covers light-emitting diodes (LEDs), laser
diodes, organic LEDs, and any other semiconductor light sources; control
gear; LED-drive circuits; and microwave power supplies for
Other products include decorative, infrared,
PAR, projection, reflector, sealed beam, special-purpose, and three-way
incandescent lamps, as well as tungsten halogen lamps.?
are leaders in developing a means to measure and define acceptable
limits for temporal light artifacts (i.e., flicker and stroboscopic
effects), with a focus on LED technology. They also address power
quality, harmonics, photobiological issues, infrared radiation, and
luminaire best practices.
