WHAT IS LED?

@2012 Nessa company confidential www.nessa.in

Key Parameters
Luminance
o Light reflected from a surface in a given direction when we see
an object
Correlated Color Temperature – CCT
o Color appearance of a lamp
o Measured in Kelvin (K)
o Warmwhite, Neutral, Cool White
Colour Rendering Index – CRI
o Light sources differ in their ability to render color of objects
“correctly”

LED Advantages
High durability of LEDs lasting for more than 10 years. In
comparison, the conventional sodium and CFL lamps typically
require replacement once every year
Environment friendly and easy disposal due to absence of
harmful substances like mercury and lead
Higher color temperature of light
Higher CRI: More vision clarity
Low heat emission
Cleaner and Greener environment to breathe!
Payback period of less than 1.5 years due to 1/3 power
consumption

So what’s the problem ??
Conventional lights have high power
consumption
They fail very frequently and high maintenance
required
Even the LED lights have been found to fail
very frequently in India

How do we differentiate?
Thermal Management
Driver/Controller Design
Suitable optics and simulations
Recycling and safe disposal of existing sodium lamps
@2012 Nessa company confidential www.nessa.in
13
Thermal Management of LEDs
Highly thermally conductive solder points and thermal contacts
Mounting of LEDs so as to maximize the surface area and reduce thermal
resistance
Primary Heat-sink (MCPCB) with highly thermally
conducting dielectric and Aluminum 5052 base
Secondary Heat-sink (Streetlight body) with die
cast aluminum alloy and optimal number of fins
Theoretical 60,000 hour life becomes practical

Driver/Controller Design
High AC-DC efficiency of more than 90%
Matrix architecture
Inbuilt power factor correction of 0.952
High voltage fluctuation range of 85-275 V
Inbuilt spike guard for high voltage spikes
Magnetic isolation
Up to 3000 V Electrostatic Discharge tolerance
@2012 Nessa company confidential www.nessa.in
15
Suitable optics and Simulations
Inbuilt asymmetric lenses for
rectangular spread
Low optical losses because
of primary lens
Uniform spread and no dark
spots
30 W of LED ≅ 70 W Sodium
lamp No, not lumens to lumens but lux to lux
High values for Eav and U
