This work presents performance analysis of an LED luminaire, applied simultaneously for lighting and communication in visible light communication systems (VLC), indoors ( emphindoor). The performance analysis of an optical concentrator coupled to the luminaire by means of photometric and radiometric measurements is presented, with its characteristics reproduced and simulated in the SolidWorks® and APEX ® pieces of software. The simulations were compared with measurements in the laboratory, aiming to use this software in more realistic predictions of VLC systems and in the analysis of optical components. The results highlight the importance of detailing the optical characteristics of the materials used in the simulations, as well as the need for power calibration of the LEDs. In simulations carried out at 1.70 m distance, illuminance levels of up to 1351.59 lx and BER estimates of: 4.88×10−2 (OOK); 11.99×10−2 (8-QAM); and 17.20×10−2 (16-QAM). Considering a 3.82 dB gain in the reception front-end, the BER estimates improve to: 3.27×10−5 (OOK); 3.90×10−3 (8-QAM); and 27.80×10−3 (16-QAM). Experimentally, a gain of up to 8.59 dB was achieved in the transmission with the use of the optical concentrator.
