INTRODUCTIONInduction lamps are high frequency (HF)

light sources. operate without electrodes. The absence of the electrodes in theinduction lamps enhances the lamp life.

The invention of induction lighting isbased on the principles of induction andlight generation via a gas discharge.

How It Worksy They work like Fluoroscent tube without

electrodes.

y Magnetic field is produced by 2-transformercoil.

y This creates an electric field in a glass tube.

y Electric field creates a discharge in the tubewhich radiates light.yWorks like a transformer:

y Coils are primary; lamp is secondary.

WhyInduction Lamphas such a

long life?y The loss of cathode emission materials due to-

evaporation and

sputteringcaused by ion bombardment.

y life of fluorescent lamps to between 5,000 to 15,000hours. The long life time of the induction lamps allow

them to be applied in cases where lamp maintenanceand access are very difficult or expensive.

ConclusionsyComparing with other key IEFL

products, LVD IEFL with the IC chipshas good photometric and electricalfeatures on its highest luminanceefficacy, good dimming characteristicand lowest price.

yLVD IEFL is a good choice because ofits high performance cost ratio.
