The issue of light pollution, unnecessary lighting of outdoor areas, came into focus in the last 10 years. This is the reason why observatories should not be built in highly populated areas, it also disturbs the wild life, and it raises questions about energy conservation too. Based on its capabilities, LED technology offers a solution to this problem. Nowadays, travellers can visit many cities in developed countries and encounter LED street lights in streets as application of this technology spreading in public lighting. Designing orientation of LEDs in such street lights is a difficult problem as we need to use multiple LED packages to light an as large area as an incandescent light bulb can. Determining correct angles is a global optimization problem, a complex mathematical task related to the field of covering problems. In this chapter, we present an automatic designing method to construct LED configurations for street lights and a light pattern computation technique to evaluate these configurations. To speed up the whole designing process, a possible way of parallelization is also discussed.
