1. A method of evaluating lighting quality in a geographic region having a plurality of luminaires arranged therein, each luminaire comprising a tilt sensor arranged for obtaining a tilt angle of said luminaire, the method performed by a computing device and comprising the steps of:
receiving tilt angles of said plurality of luminaires obtained, via a communication device, obtained by tilt sensors of said plurality of luminaires, and
evaluating lighting quality in said geographic region, via an evaluating device, with reference to a number of parameters derived from said received tilt angles of said plurality of luminaires;
wherein said number of parameters comprises at least one of the following parameters:
one or more lighting level indicators;
one or more lighting uniformity indicators,
a threshold increment, and
a surround ratio;
wherein said step of evaluating comprises:
calculating said number of parameters based on said received tilt angles of said plurality of luminaires and geographic settings and other luminaire installation settings, and
comparing said calculated number of parameters with respective reference values of said parameters.
