FUNCTION: cooling
blood flow heat dissipation
increased number of vessels close to the surface
vasodilation
Pine cones - opening
termite nests - passive warm air evacuation
look at how animals in hot places loose heat

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
MODULAR
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
EVOLVABLE
create a lamp that can grow - you can add more and more light bulbs

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?
Alveolar vascularisation
Spider net
exemple of heat absorbing glass, does not store it, rediffuse it in the air
