LED technology offers new opportunities for lighting in the form of dynamic light sources. The authors of this article have analyzed an integrated LED system in terms of improving their overall performance, based on its modeling and simulation. An original methodology for determining the optical, electrical and thermal characteristics of coloured and white LEDs, using specialized software, was proposed. The operational optimization of LED-based lighting system, with special attention to the influence of thermal effect over the integrated system, was conducted. It was studied the reliability of the LED system in order to analyze the extension of its life duration. Based on the results obtained from the simulation of the analyzed LED system, the authors have highlighted a very good agreement between the numerically modeled and the literature-based experimentally determined electrical, optical and thermal characteristics for the two operating modes (forward mode and reverse mode) and cooling modes (with heat sink and without heat sink), respectively..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
