Solar Energy and Solid Sate Lighting

Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies such as solar power to generate electricity, solar thermal energy (including solar water heating), and solar architecture. It is an essential source of renewable energy, and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power, and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light-dispersing properties, and designing spaces that naturally circulate air.

Solid state electroluminescence is used in SSL, as opposed to incandescent bulbs (which use thermal radiation) or fluorescent tubes. Compared to incandescent lighting, SSL creates visible light with reduced heat generation and less energy dissipation. Most common "white LEDs” convert blue light from a solid-state device to an (approximate) white light spectrum using photoluminescence, the same principle used in conventional fluorescent tubes.

Engineering Applications of Spectroscopy

IR spectroscopy is mainly used for identifying the chemical composition of the material. Fourier transform infrared (FTIR) spectrometers mainly use IR spectroscopy techniques. The electromagnetic spectrum of infrared is mainly classified into three types namely, near-infrared, far-infrared and mid-infrared. â€‹Theoretical spectroscopy, typically based on first principles density functional theory (DFT) computations, can provide a link between the material structure and the spectra measured. These calculations can aid the design of experiments, or assist in structure solution. A fiber-optic sensor is a sensor that uses optical fiber either as the sensing element ("intrinsic sensors"), or as a means of relaying signals from a remote sensor to the electronics that process the signals ("extrinsic sensors"). Fibers have many uses in remote sensing. Depending on the application, fiber may be used because of its small size, or because no electrical power is needed at the remote location, or because many sensors can be multiplexed along the length of a fiber by using light wavelength shift for each sensor, or by sensing the time delay as light passes along the fiber through each sensor. Time delay can be determined using a device such as an optical time-domain reflects meter and wavelength shift can be calculated using an instrument implementing optical frequency domain reflectometry.
