3. Introduction
 According to a Press Information Bureau (PIB) announcement, by
2019, 770 million LED bulbs and 35 million LED streetlights will be
deployed to replace conventional lights.
 Over 2.1 million conventional streetlights have already been replaced
with LED streetlights across the country, under the Street Lighting
National Programme (SLNP).
 The installation of LED streetlights has resulted in annual energy
savings of 295 million kWh and reduced carbon emissions by
2,30,000 million tonnes annually. The project has been implemented
across 23 states and union territories.

 Most modern LED operate in a range of 2 to 4 volts and consume
anywhere between 350mA and 1500mA.
 Power consumption of LED light bulb is only 10% of the standard
light bulb.
 LED light bulbs withstand great amount of vibration, shock and
temperature variations.
 LED light bulbs are 10-60 times more energy efficient than
incandescent light bulbs.
 Incandescent light bulbs produce light that flickers whereas LED light
bulbs produce flicker free light.
 LED bulbs can produce many rich and vibrant colors when compared
to incandescent light bulbs.

Changing Scenario of Lamps

9. 9
 Smart connected LED lights: Lighting systems will get smarter, as the
possibility of autonomous, self-commissioning illumination systems is
emerging.
 Changes in ‘on board technology’: This will also reduce the number of
components compared to those used in traditional drivers. Use of fewer
components can reduce costs while enhancing the efficiency of the final
product.
 Use of Chip Scale Packaging (CSP) technology: This will enhance
lumen output and also increase the reliability of the final product.
 Introduction of driverless low voltage direct current (LVDC)
operated products: This will enable energy saving by reducing AC-DC
current conversion losses.
Emerging Technology Trends in
LED

10. 10
 Low electrical consumption as compared to conventional lighting
products.
 Pollution free due to non-emission of infra red or ultraviolet
rays, mercury gases or other harmful rays.
 Existing fixtures used since long are used making installation of our
lights easy.
 Due to long shelf life, no maintenance is required.
 Reduces Carbon Footprints at large scale making it viable to
earn carbon credits.
 Energy savings about 30 to 50 %.
 Less heat dissipation, which reduces the air conditioning load.

12. Conclusion
 Use of energy efficient lamps like LED, lead to enormous
amount of energy savings which is estimated as 50 to
80%.
 The existing systems cannot be successfully applied to
home and office buildings. Therefore, we propose an
intelligent household LED lighting system considering
energy efficiency and user satisfaction.
 The proposed system can be autonomously adjusted to
the minimum light intensity value to enhance both energy
efficiency and user satisfaction.
