Infrared To Electricity

All objects in the universe emit some level of ir radiation.

Infrared to electricity.

Depending on the temperature of the emitting body the wavelength of the peak of the infrared radiation ranges from 780 nm to 1 mm. An infrared heater or heat lamp is a body with a higher temperature which transfers energy to a body with a lower temperature through electromagnetic radiation. The more power that s flowing through a single circuit the easier it is to get the components to do what you want. Infrared radiation ir or infrared light is a type of radiant energy that s invisible to human eyes but that we can feel as heat.

Infrared heaters can be powered by electricity natural gas or propane. No contact or medium between the two bodies is needed for the energy transfer. Infrared heat is safer than conventional resistive heat but it takes just as much electricity to produce it. Sunlight at an effective temperature of 5780 kelvins 5510 c 9940 f is composed of near thermal spectrum radiation that is slightly more than half infrared.

If you re harvesting energy from infrared emissions the voltage will be relatively low explains byrnes. Thermophotovoltaic tpv devices are similar to ordinary photovoltaic devices in concept and form except that tpv devices produce electricity from ir as well as visible light. However even with the best modern infrared diodes there is a problem. At zenith sunlight provides an irradiance of just over 1 kilowatt per square meter at sea level.

Different heaters will have different maximum output levels different controls and different designs. The rating for a particular heater is specified on a label usually affixed near. Of this energy 527 watts is infrared radiation 445 watts is visible light and 32 watts is ultraviolet radiation.
