Welcome to South African Induction Lighting

 

 Magnetic induction lamps are basically fluorescent lamps with electromagnets wrapped around a part of the tube, or inserted inside the lamp. In external inductor lamps, high frequency energy, from the electronic ballast, is sent through wires, which are wrapped in a coil around the ferrite inductor, creating a powerful magnet. The induction coil produces a very strong magnetic field which travels through the glass and excites the mercury atoms in the interior which are provided by a pellet of amalgam (a solid form of mercury).

The mercury atoms emit UV light and, just as in a fluorescent tube, the UV light is up-converted to visible light by the phosphor coating on the inside of the tube. The system can be considered as a type of transformer where the inductor is the primary coil while the mercury atoms within the envelope/tube form a single-turn secondary coil.

 

Financial Savings and Total Cost of Ownership

Induction lamps offer the benefits of financial savings through:

  • Energy Savings

  • Lighting Performance

  • Maintenance Savings

  • Health and Safety 

  • Environmental Protection.

While the initial investment in induction lights appear to be high, the total cost of ownership is more than half of that when comparing to traditional technologies. In most cases, the payback of the initial investment through savings is between 2 to 3 years.

 

Energy Savings

Induction Lamps have a high lighting efficiency.  The efficacy is between 65~90 lm/w for lamps from 40W to 300W respectively. The cost savings comes from the actual lighting design application. Lighting application must take into account things such as the rate of light depreciation, the colour rendering required by the client, etc, because the light depreciates very slowly, one can design knowing that the light loss factor is very low.

The only deficiency when it comes to using induction lamps is the heights. As one goes higher to heights of 15 – 25 meters, there is a trade off between the number of induction lamps required versus the energy savings. However, the maintenance savings at these heights is significant enough to warrant the investment in induction lamp technology.

To further solve the problems of energy savings when dealing with heights of 15 meters please see our Plasma Lighting technology.

 

Health  & Safety

  • Quick start: Instant start whenever lighting supply is cut off. This also occurs even when the lamp is hot or if ambient temperature is low (-40 – 50 degrees).

  • High-frequency working, no flash and soft lighting for eyesight protection. There is no flicker and glare that impairs vision and strains the eye.

 

Maintenance Savings

Induction Lamps have a life expectancy of between 80,000 to 100,000 hours. This is equivalent up to 4 re-lamps for HPS and Mercury Vapour lamps (see table 1) .  Over and above this, induction lamps have a high lumen maintenance rate (low light decay)  of 70% after 60,000 hours (see below).

 

Lighting Performance

  • High lighting efficiency: more than 65~90 lm/w, equivalent to 8 or 9 pcs of  incandescent lamp in the same wattage.

  • High color rendering index: 80, high resolution & clear and clean color.

  • High power factor: more than 0.95 resulting in less investment in power cable.

  • Optional color temperatures (2700-6500K) suitable for difference needs.

  • Constant wattage output: The output wattage is less than 3% with the input voltage variation at ―20%.

 

Environment Protection

  • Uses Solid Mercury: 0.25mg of mercury per 100W of light.

  • Less waste on lamp replacements:  lamps last up to 100 000 hours – less waste in terms of phosphor disposal.
