【 摘 要 】

When utilizing TEG (thermoelectric generator) module, it is important to know the performance of the TEG under focal length of a concentrating lens from energy radiation sources. To do this, incandescent lamp is used an artificial lights experimentally. Then, a design prototype of the TEG's testing using Fresnel lens as optical radiation concentration prior to heat the TEG will be applied during the test. The test was conducted under laboratory scale using three power differences, 40, 75 and 100 Watt. White painted acrylic sheet is used as an envelope wall of the prototype to optimize walls heat radiation inside the design. Finally, The remo spectrometer has been using to measure the wavelength of each power. The result shows that the higher powers of the lamp, the bigger ranges are the spectrum of incandescent light with exception of 75 watt power. It could be more varieties spectrums of the higher power lights.
