….a new concept in energy efficient lighting
1890s:
Basic principle demonstrated by Nikola Tesla.
1968:
General Electric applied for patents for electrode-less(Induction)
lamps.
1992:
Philips introduced their QL systems in US and European market.
1996:
Osram and GE started selling their induction light systems.
2005:
Amko Solara of Taiwan enters the market.
2007:
China enters the Induction Light market.
2011:
Karee Lighting (India), 1st Indian Manufacturer , begins
production of Induction Lighting systems.
A hybridised form of fluorescent
technology, without electrodes(filaments).
Power is transferred into the sealed
glass tube through electromagnetic
induction.
Two ferrite inductors
around the tube.
are
wrapped
High-frequency power is delivered from
the lamp ballast to the ferrite inductors.
Alternating magnetic field created by
the inductor assembly excites Mercury
atoms in the inert gas-fill, producing UV
radiation.
UV
radiation is down-converted to
visible light by the phosphor coating on
the inside of the tube.
 The human eye is not equally sensitive
to all wavelengths of visible light.
 This function shifts according to the
lighting conditions.
 Human Vision in “Day Light” is
“PHOTOPIC VISION”.
 Human Vision in “ Dark ” is “SCOTOPIC
VISION” .
 Conditions between “Day Light &
Darkness” activate the “MESOPIC
VISION”.
 Normally, we are living/ working in
“MESOPIC” conditions.
Comparison of Metal Halide source with Induction Source

Metal Halide
Gives less visibility in scotopic/mesopic
range)

Induction
Gives more visibility in scotopic/mesopic
range)

High-Pressure Sodium
Vapour (very low visibility in
scotopic/mesopic range)

Induction
(more visibility in
scotopic/mesopic range)
The Scotopic to Phototopic ratio or multiplier:
INDUCTION LAMPS
“Long-Haul Trucks of the Lighting Industry”
 Long lifespan due to absence of Electrodes(filaments)
 Minimal lumen depreciation over lifespan.
….the Indian advantage
"The scientific man does not aim at an immediate result. He
does not expect that his advanced ideas will be readily taken
up. His work is like that of the planter - for the future. His
duty is to lay the foundation for those who are to come, point
the way"
- Nikola Tesla
Rugged electronics design architecture to suit
local conditions.
 High ambient temperature sustainability (-20
to 60ºC)
 Recommended operating range : 140V-280V
 Overvoltage and Under voltage protection.
 Prompt and efficient technical service and
support.
 Capability for customized solutions.

In case Induction Lights are installed, due to lower power requirements,
lower size of cables/wires, transformers, MCB's etc. can be used and
therefore the overall lighting project cost will go down.
