Induction Lighting

1. What is Induction Lighting?

An induction light is similar to a fluorescent light in that mercury in a gas fill inside the bulb is excited, emitting UV radiation that in turn is converted into visible white light by the phosphor coating on the bulb. Like fluorescent, the phosphor coating determines the color qualities of the light. Fluorescent lamps use electrodes to strike the arc and initiate the flow of current through the lamp, which excites the gas fill. Each time voltage is supplied by the ballast and the arc is struck, the electrodes degrade a little, eventually causing the lamp to fail. Induction lamps do not use electrodes. Instead of a ballast, the system uses a high-frequency generator with a power coupler. The generator produces a radio frequency magnetic field to excite gas fill. With no electrodes, the lamp lasts longer.

2. Where can Induction lighting technology be applied?

Induction lamps are ideally suited for high-ceiling applications where the lamps are difficult, costly or hazardous to access. They are also ideally suited for such applications where the advantages of fluorescent lighting are sought, but a light source is needed that can start and operate efficiently in extremely cold temperatures. As a result, induction lighting is suitable for a wide range of applications, including not only warehouses, industrial buildings, cafeterias, gymnasiums, etc., but also signage, tunnels, bridges, roadways, outdoor area and security fixtures, parking garages, public spaces, and freezer and cold storage lighting.

3. What advantages are there for induction lights v. metal halides?

The biggest advantage that induction lighting has over metal halides is the ability to instantly start and shut off.

Another advantage induction lighting has over metal halide is lumen maintenance. Most significantly, at 40% of service life, metal halide’s light output and efficacy experience severe degradation. A 400W metal halide lamp, for example, may produce 36,000 lumens but 25,000 at 40% of life, a 30% decline. Therefore, unless the lamps are periodically group-relamped, a large system’s “average” performance over time is much lower than its initial ratings.

Tests carried out on a 200W Induction lamp found that it retained 82% output after 20,000 hours (that’s already more than the rated hours on metal halides) and still put out 70% after 60,000 hours. Where metal halide bulbs are concerned, at least six replacements would have been required during this period, the last bulb would be running at 50% output.

Scientific Data:

Induction lamps produce high quality white light. Recent studies favour white light (as from induction lamps) for viewing moving objects in low-light conditions, such as spotting a pedestrian, animal, or other moving objects on the side of the roadway at night. Some cities opt to use white light rather than the yellowish light of high-pressure sodium in hopes of reducing accidents.

The improved colour-rendering of white light in retail areas and places where people congregate after dark make it a popular choice for street lighting in down town areas. More lamps and fixtures are becoming available and applications are expanding. The long life of these lamps can substantially reduce maintenance costs previously incurred due to re-lamping.
