Modern LED luminaire concept for road lighting
 Krejčí, Miroslav ; Kovářová, Klára (referee) ; Novotný, Jan (advisor)
This thesis deals with design of optical system for road lighting luminaire. In the beginning the basic photometric quantities and assessment methodology for requirements of lighting class M are described. The next step is the programming of algorithm which evaluates the road lighting requirements using few boundary conditions. The input of the algorithm is also luminous intensity (power emitted in a particular direction). By the turning the algorithm over, it is possible to evaluate the luminous intensity from the road lighting requirements. Those luminous intensities are used in the process of modification of optical lens. The ray tracing of modified models of lenses was performed to obtain the tables of luminous intensity. The values of luminous intensity are verified in the same algorithm. Finally, the comparison of results was made including several luminaires out there.
