Induction Light

What is induction lighting?

efficient – durable – low maintenance – environmentally friendly

The principle of induction light was discovered by Nikola Tesla in 1891. Thus, this technique is not new. Unfortunately it took until now to realize the production readiness and implementation of this technique for efficiant and profitable serial production. For induction lamps, the gas discharge from the outside is excited inductively, i.e. coupled electromagnetic fields in the air (induced). The difference in the fluorescent tubes or gas discharge lamps such as MHL, MVL, HPS is the difference as the electrons are generated. In the fluorescent lamps, MHL, MVL, HPS between two electrodes, the electrons are generated in the lamp. This means abrasive wear of these parts. For the induction lamp, the gas discharge is excited inductive. So the electron electromagnetic fields is stimulated to emit light. This has the advantage that no abrasive wear, as in the above-mentioned lamp is present. Thus, the lifetime increases by a multiple.

Why only now ready for series production?

Only since 10 years It’s been possible to produce high-frequency electronic ballasts for profitable costs and a qualitative acceptable serial production.

Why energy saving?

Energy conservation is becoming increasingly important in today’s time. A large part of the energy is driving the need for light needed (24%). Lighting costs are made up of capital costs (purchase and installation) and operating costs, divided in the item maintenance (lamp replacement, maintenance) and energy. At this total expenditure have to purchase and maintain stakes of 25%. Half of the total cost is caused by the energy consumption of the lighting. It is clear that lower energy consumption – which means high light output – as well as long life greatly reduce the cost and very low maintenance. Since the induction lamp combine all of these features, they are very economical lamps with very high quality of light. In the short term can not be quantified in euros and cents is better lighting quality (compared to LED f.e.) and in comfort with the use of induction lighting.

A few advantages of induction lighting:

  • excellent quality of light
  • features that enhance the visual comfort
  • flicker-free instant start
  • flicker-free light
  • dimmable light (associated with energy saving)
  • long lifespan of at least min. 100,000 hours of operation (corresponding to min. 14 years at 24/7 on-time)
  • less light loss (20% after 100,000 hours)
  • ¬†the light yields from 80 to 90 lumens per watt, based on the actually perceived by the human eye light there are up to 150-pupil lumens per watt (so-called. VEL value)
  • low CO2 emission
  • very low maintenance
  • by using solid amalgam mercury instead of mercury vapor induction lamps are not harmful and environmentally friendly

The quality of induction lighting

The fact that induction lighting has many shares of green and blue light, it is a excellent quality light unlike other lighting systems such as LED, MVL, etc. Our eye is so constructed that it can see in the dark better if a lot of blue and green light is available. The eye has become accustomed in the dark under the moon light to see better, having many blue and green light components. Background of this nature lies is in the evolution of the human. The eye has become accustomed to see better in the dark under the moon light. With LED and sodium vapor lamps, these blue and green light spectra are insufficiently. LED light is therefore very flashy and dazzling. Sodium vapor lamps (HPS) on white rather have a yellow, ghoulish light. Thus, in both systems is the high visibility at night not really given as with the induction lighting.

Operation of the induction light

In contrast to conventional high-pressure, low-pressure gas discharge lamp, the UV radiation electrode is excited from the outside by a high frequency alternating (210kHz) magnetic field. This one has no abrasive wear. In the interior of the glass bulb is an inert gas (typically argon, which is present at 1% in the respiratory air) having a low content of amalgam in a solid form. The generated UV light delivered on a fluorezente coating (usually on a phosphorus base) on the inside of the glass bulb. The coating converts the UV radiation into visible light similar to day light. Characterized in that the amalgam is present in solid form in the glass bulb, there is no health hazard as with mercury vapor lamps (MVL) at damage.
