Induction Lighting Is Green Brilliance

839870224 Times As Efficient and Lasts Over 20 Times Longer

Sometimes called the electronic light bulb, the induction lamp offers high efficiency and a very long life because it operates without an electrode nor a filament. At the center of the lamp is the induction coil powered by an electronic unit at the base of the lamp. This coil produces a magnetic field in the lamp that ultimately produces light. This coil is sometimes referred to as an energy-coupling antenna. Since the induction lamp has no filament to burn out, so the lamp does not fail catastrophically as do incandescent bulbs. As the phosphors in the glass housing age, the induction lamp simply dims.

The glass assembly surrounding the induction coil contains a mercury electron-ion plasma material. This material is energized in a magnetic field producing UV light. The inner portion of the glass is lined with a phosphor coating very similar to that in fluorescent lamps. Finally, the base of the lamp is a standard Edison base or medium screw base just like those on most incandescent lamps. This makes it useable in a variety of applications offering improved efficiency.

The induction lamp is designed to light immediately with no warm-up period or flicker. When high frequency power is supplied to the induction coil, an electromagnetic field is generated within the lamp. This field excites the plasma material inside the glass housing causing the mercury atoms to emit ultraviolet light. When the UV light passes through the phosphor coating it’s converted into visible light in very much the same manner as fluorescent lamps.

Compared with the incandescent lamp, the induction bulb is about 4 times as efficient and lasts over 20 times longer. In fact, these lamps are rated between 10,000 and 20,000 hours. Quite an improvement over incandescents which burn only 750 to 1,000 hours.

With such a long rated life, these lamps seldom need replacing. Particularly useful in applications where lamp replacement is cumbersome and expensive, as in hard-to-reach areas. Practically maintenance-free, the induction lamp offers many features that make it an attractive light source. It also produces high quality light in a variety of colors. This gives lighting designers more options in their designs. As a compact source, the induction lamp can be used in a wide range of fixtures, adding further flexibility for the lighting designer.

The induction lamp is durable, ideal for outdoor applications where durability is certainly a high priority. Its light output is not significant influenced by ambient temperature. Relatively insensitive to line voltage fluctuations, its light output remains constant over wide range of input voltages.

This video will give you more insight into induction lighting, although I have no info on the company in the video and therefore no endorsement is inferred. Also, thanks to Lissof for the heads up on this technology!

…. as the green future unfolds.

    A piece of vital information is missing here: how much will this new technology cost? And is it a lightbulb that the average joe can buy and replace all the lightbulbs in his home with? Amazing technology, but if it isn’t sustainable economy-wise, it won’t catch on.

  2. Linda Says:

    Hi gochi … The cost is unknown at this point. It will be watched and updated when published. Just letting you know what is on the horizon and yes, it should be available for the average joe. UPDATE: The cost for the entire area lamp is around $330.00.

  3. Karen Says:

    Very interesting. I wonder if they are a lot more expensive.

  4. Linda Says:

    Hi Karen … Not sure at this point but we’ll be watchin!

    It is encouraging that new technologies in lighting are being developed. It is also promising that this method will be available in many color temps as the recent LED bulbs I tried were dismally disappointing. Perhaps it was just the brand but the light output was very understated.

    Hi Earth Friendly … In some cases, the LEDs are understated. There are some that are brighter so you just have to be sure what you get.

    I always learn something new here 🙂

    Hi vein … That is great! we try to educate all visitors… 🙂

  9. Brad Says:

    Hi Linda.

    Nice description of how this technology is put together and developing. It’ll be interesting to see where it ends up in the cost-effectiveness spectrum.

  10. Linda Says:

    Hi Brad … Thank you and hopefully it will not be pushed under the rug.

  11. Induction Lamps Says:

    Very nice explained about working induction lamps,i really liked this blog as it really helped me a lot, and being one of manufacturers of Induction lamps we agree that these lights economical, Eco friendly and energy saving and having long lifespan.
