Induction Lighting

Induction lighting is changing the way businesses and homes are being lit — saving money, saving energy and saving the environment. The primary benefits are:

• Long lifespan due to the lack of electrodes – between 65,000 and 100,000 hours depending on the lamp model
• Very high energy conversion efficiency of between 62 and 90 Lumens/Watt
• High power factor due to the low loss of the high frequency electronic ballasts
• Light stays bright as lamp gets older (less lumen depreciation compared with other lamp types)
• “Instant-on” and hot re-strike, unlike most conventional lamps used in commercial/industrial lighting
• Environmentally friendly as induction lamps use less energy and use less mercury per hour of operation than conventional lighting

David Houghton recently reported in Architectural Lighting Magazine:
The main attraction of induction lighting is incredibly long lifetime. In a fluorescent lamp, the electrodes at either end are the weakest link, and the lamp usually fails when the cathode coating on one of the electrodes is depleted after 15,000–20,000 hours. Induction lamps have no such electrodes, so their rated lifetimes are as long as 100,000 (that’s over 11 years, running 24/7!). They also have good vibration resistance and low starting temperatures, making them a good choice for rugged operating environments.

Induction lamps are discharge lamps, where the idea is to get mercury or other atoms to elevate their energy level, then discharge a photon as they fall back to normal. Induction lamps differ from fluorescents-their closest relative in the lighting family-in the way they energize the mercury atoms. Instead of striking an arc between electrodes in a tube, an electromagnetic field is generated by a carefully shaped coil. The field created by the coil induces a current flow in the gas/mercury blend within the lamp. This current excites the mercury atoms and starts the flow of photons. Mercury atoms emit UV photons; phosphors lining the lamp wall absorb the UV photons and in turn emit visible photons.

Like high-quality fluorescents, induction lamps offer instant strike, instant restrike, color stability, 80+ CRI, high power factor and low THD. A ballast-in this case called a field generator-is required to provide the power electronics that drive the induced current in the lamp. Finally, induction lamps have a coupling device that wraps the induction coils around some part of the lamp itself. Induction technology is not dimmable at this time, but it could be in the future.
