The photometric modeling of LEDs as generalized Lambertian sources (GL-Sources) is discussed. Non-Lambertian LED sources, with axial symmetry, have important real-world applications in general lighting. In particular, so-called generalized Lambertian

In this paper, the foundations of radiometry and photometry, based on Second Principle of Thermodynamics are discussed, in terms of brightness (luminance), and etendue (Lagrange invariant) limitations of integrated lighting systems. In such a case, t

Most state-of-the-art commercial, industrial, and military display technologies require some type of backlight illumination. Optimization of such lighting systems with respect to brightness, uniformity, and viewing angle is critical to achieving tech
