BIO-CHALLENGE: LIGHT BULB
FUNCTION: Light Transmission
moth's eye antirefelctive surfaces - increases the light that passes through - prof. Yves Leterrier at EPFL

FUNCTION: Light Scattering
BIOLOGIZE: Snail Shell
blood flow heat dissipation
increased number of vessels close to the surface
Pine cones - opening
termite nests - passive warm air evacuation
look at how animals in hot places loose heat
INTERESTING NOT BIOINSPIRED
Stylish energy efficient lights
WHAT WE KNOW ABOUT LIGHTNING
Basic data on different LED and CFL lights
WHAT ARE THE CURRENT CHALLENGES WITH LED AND CFL????
Temperature inside the LED can rise up to 90 degrees
LIFE'S PRINCIPALS APPLIED TO LIGHT
replacing only the upper part of the bulb where the LED is, not the whole bulb - reduced waste?
playing with many small bulbs - maybe more light, in different directions !
MULTIFUNCTIONAL - for what other function could light bulb and lamp be used for. :
how coudl we reuse heat energy lost - although maybe LED is not producing that much heat
create a lamp that can grow - you can add more and more light bulbs
INFRARED LIGHT wavelength 1μm-1mm
IR = HEAT
Corps humain source d'
Polar bear scattering
IR cutoff filter = heat-absorbing filter
Imagine we want to put such a filter on the top of a light buble, what shape could we use?
exemple of heat absorbing glass, does not store it, rediffuse it in the air
mode de transfert thermique : conduction ou rayonnement
Exemple d'application :
Lampe de poche
HEAT TO ENERGY TRANSFER
HEAT TO ELECTRICITY
HEAT TO CHEMICAL E
