Indoor LED Luminaire Reflector Profile Optimization to Minimize the RUG Glare Index

The paper presents a methodology for optimizing an optical system, in terms of the
$R_{UG}$
glare index, by iterative change of the reflector shape of an indoor LED luminaire with rotational symmetry of the light distribution intended for indoor workplaces. Building of 3D models of an optical system of indoor LED luminaire by iterative changing of the reflector shape by using software for optical design and photometric analysis was made. Comparative photometric analysis using the Monte Carlo raytracing method of the modelled optical systems with an iterative change of the reflector shape of the LED luminaire to calculate their photometric characteristics was done. Comparative lighting calculations with an optimum criterion – minimizing of
$\boldsymbol{R}_{\boldsymbol{UG}}\leq \mathbf{19}$
, meeting the requirements of lighting standard for a typical office room, through the analysis of which the optimal solution is found.
