Located in media Figure 2 - Some standard heatsinks out of a broad range. Located in media Figure 1 - Luminous flux vs ambient temperature for red LED by constant current (according to documents from the company Lumileds ). Located in media HOW IT WORKS: Conventional and magnetic refrigeration cycles use different physical effects to cool things off. [Top] When a gas is compressed (2), it heats up, but if it is cooled and then allowed to expand (3), its temperature drops much lower than it was originally (4); this principle keeps food in your home refrigerator cool. But a magnetocaloric material [bottom] heats up when magnetized (b); if cooled and then demagnetized (c), its temperature drops dramatically (d).
