Energy harvesting Heat sink Used to absorb and dissipate heat from the device to the ambient using conduction, convection and radiation. In this application, it keeps the cold side of the TEG cool.
Heat spreader Used to evenly distribute the heat over the surface of the heatsink.
Energy harvesting, or energy scavenging, is the process of capturing waste energy, such as heat or pressure, and converting it to electrical energy. LEDs release a portion of their consumed energy as heat, energy that is wasted. This energy can be captured and redirected to supplement or replace electrical energy that would normally be required from the grid, as well as reducing the power consumption of systems used to counteract the effects of the emitted heat. The thermoelectric generator (TEG) is an innovative device that harvests the heat energy emitted from an LED luminaire and converts it to electricity by connecting two different semiconductor materials in a series configuration to produce a net voltage that can be driven through a load.
TEG A thermoelectric generator that uses the Seebeck effect to harvest energy by converting waste heat into useful electrical power.
