  4. Jones calculus - Wikipedia

    en.wikipedia.org/wiki/Jones_calculus

    The Jones vector describes the polarization of light in free space or another homogeneous isotropic non-attenuating medium, where the light can be properly described as transverse waves. Suppose that a monochromatic plane wave of light is travelling in the positive z -direction, with angular frequency ω and wave vector k = (0,0, k ), where the ...

    LED lighting does not typically fail, but instead decreases in output until it needs to be replaced. [2] It is estimated that installation of energy efficient street lighting in the 10 largest metropolitan areas in the U.S. could reduce annual carbon dioxide emissions by 1.2 million metric tons, the equivalent of taking 212,000 vehicles off the ...

  9. Sulfur lamp - Wikipedia

    en.wikipedia.org/wiki/Sulfur_lamp

    Sulfur lamp inside a Faraday cage, which is necessary to prevent microwave radiation leakage from the magnetron which would cause radio interference. The sulfur lamp (also sulphur lamp) is a highly efficient full-spectrum electrodeless lighting system whose light is generated by sulfur plasma that has been excited by microwave radiation.
