INTRODUCTION

Light, the source and soul of illumination.

Light is the most important tool of guidance

Source of energy that turned darkness into productive outcomes.

Basis of origin ,sustainability and existence.

UNESCO delegates proposed the mission underlying the INTERNATIONAL YEAR OF LIGHT.

THE AIMS OF IYL 2015

To raise awareness To promote sustainable

development To reduce light pollution

and energy wastes It is an opportunity to

celebrate the power of the human imagination

To promote understanding of the central role of light

SCIENTIFIC INNOVATIONS

SCIENTIFIC INNOVATIONSSOLAR PANEL• Used to power all sorts of electronic equipment• Also placed on outdoor lighting structure

LED• Extremely energy efficient• LEDs have a higher initial cost and a long

lifespan(60000hr)

PHOTONICS• CONSUMER ELECTRONIC• TELECOMMUNICATIONS• MANUFACTURING INDUSTRIES• DEFENCE AND SECURITY

LI-FI TECHNOLOGY:• Li-Fi enabled street lamps, would provide a network of

internet access points• Light can penetrate for large distances and can enable

communication

FIBRE OPTICS AND OPTICAL FIBRE:• Telephone transmission method uses fibre-optic cables.• Well suited for medical use. 

FUTURE LIGHT SOURCES LITROENERGY

New light sources that lasts for fifteen years without a recharge

Crush resistant and inexpensive Future of LED

Solid-state lighting,huge energy saving

Long lasting,durable FIPEL

Low power electroluminescent light source

More efficient than a CFL bulb

LIGHT POLLUTION: A BIG THREAT

Occurs when light used in the environment is wasted caused by uncontrolled emissions and reflection

New outdoor lighting products has also led to an increase in the light pollution levels

Urban light pollution threatens street trees

New lighting technology Government policies on

light sources Use of motion sensor-

lights and bulbs in homes Reducing or conserving

the usage of light

PREVENTION AND SOLUTIONS FOR LIGHT POLLUTION

CONCLUSION

Light is enabling the future Communication Manufacturing Health care Defence Energy

Plants that light up might be street lights in the future!
