This work focuses on the luminous efficiency of light fixtures in general and with the LED ones in particular. Applying photometry techniques, a methodology for characterizing light fixtures is outlined and followed. To achieve this purpose, a single axis goniophotometer is projected, built and demonstrated. Controlling a rotary positioner stage and aquiring measurements from photodiodes using the input analog ports of an Arduino Mega control board, the total luminous flux from a series of representative artificial light sources is calculated in order to quantify how much luminous power was lost in the various modules that compose a light fixture.Este trabalho incide na eficiência luminosa das luminárias em geral e das LED em partic...
