Abstract :In this study, the effect of luminaire angle on the path parameters of tunnel lighting was investigated. Tunnel illumination was performed with a simulation program adapted to CIE 88-2004 standards. The lighting performance parameters were compared while the angle of the luminaire was 0°, 5°, 10° and 15°. According to the simulation results, the luminaire angle is 0 degrees and the highest efficiency is reached. As the luminaire angle increased, the yield decreased in direct proportion to the angle. The highest lighting efficiency was observed at 0 degrees and the lowest illumination efficiency was observed at 15 degrees. This problem can be overcome by using a higher power lamp in angled lighting. As a result, it is revealed that angled lighting should be avoided in highway and tunnel lighting.
