SCIENTIFIC
INNOVATIONS
SCIENTIFIC INNOVATIONS
SOLAR PANEL
• Used to power all sorts of electronicequipment
• Also placed onoutdoor lightingstructure
LED
• Extremely energy efficient
• LEDshave a higherinitialcost anda longlifespan(60000hr)
PHOTONICS
• CONSUMER ELECTRONIC
• TELECOMMUNICATIONS
• MANUFACTURINGINDUSTRIES
• DEFENCE AND SECURITY
LI-FITECHNOLOGY:
• Li-Fi enabledstreetlamps,wouldprovidea networkof internetaccesspoints
• Light canpenetratefor largedistances andcan enablecommunication
FIBREOPTICSAND OPTICALFIBRE:
• Telephonetransmissionmethod uses fibre-opticcables.
• Well suited for medicaluse.

FUTURE LIGHT SOURCES
 LITROENERGY
 New light sources that lasts for fifteen years
without a recharge
 Crush resistant and inexpensive
 FutureofLED
 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
 Occurswhenlight usedinthe
environmentiswastedcausedby
uncontrolledemissionsandreflection
 New outdoorlightingproductshas
alsoledtoan increaseinthelight
pollutionlevels
 Urbanlightpollution threatensstreet
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

 Light is enabling the future
 Communication
 Manufacturing
 Health care
 Defence
 Energy
 Plants that light upmight be street lights in
the future!
