Light Source


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 screw-based.

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 electrodeless lamps.

Other products include decorative, infrared, PAR, projection, reflector, sealed beam, special-purpose, and three-way incandescent lamps, as well as tungsten halogen lamps.​

Members 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.
