1 Technical University-Sofia, Bulgaria Design of Street Lighting for Roundabouts and Conflict Zones. Guidelines on selection of lighting classes PhD Dimitar Pavlov

2 EUROPIAN STANDARTIZATION EN Table 1 Required illuminance for lighting classes CE CLASS Horizontal illuminance Е, lx Uo (minimum in-service) (minimum) СЕ 0 50,0 0,40 СЕ 1 30,0 0,40 СЕ 2 20,0 0,40 СЕ 3 15,0 0,40 СЕ 4 10,0 0,40 СЕ 5 7,50 0,40 The lighting classes СЕ are used when there aren t requirements for the luminance of the road surface or it is not applicable. This can happen when viewing distances are less than 60m, and when several positions of the observer are close.

11 Multivariable lighting calculations and typical solutions by the use of a software product Roundabout with diameter 32 meters and peripherally situated luminaires Lighting calculations for CE 1 situations

12 Multivariable lighting calculations and typical solutions by the use of a software product Lighting calculations for CE 1 situations with LED luminaire 4 LED luminaires with single power 163 W

13 Multivariable lighting calculations and typical solutions by the use of a software product Lighting calculations for CE 1 situations with LED luminaire Horizontal illuminance of the roundabout realized with LED lighting

14 Lighting calculations for CE 1 situations with LED luminaires Horizontal illuminance of the roundabout for lighting class CE 1 realized with the use of LED luminaires with overall power 653 W

15 Multivariable lighting calculations and typical solutions by the use of a software product Lighting calculations for CE 1 situations with HPSL 4 HPSL luminaires with single power 276 W

16 Multivariable lighting calculations and typical solutions by the use of a software product Lighting calculations for CE 1 situations with HPSL Horizontal illuminance of the roundabout realized with HPSL luminaires

17 Lighting calculations for CE 1 situations with HPSL luminaires Horizontal illuminance of the roundabout for lighting class CE 1 realized with the use of HPSL luminaires with overall power 1104 W

18 Lighting calculations for CE 5 situations with the use of HPSL luminaires Location of the used single luminaire in the roundabout with diameter 32 m and lighting class CE 5 Horizontal illuminance realized with the use of a LED luminaire with single power 256 W

19 Lighting distribution of the used LED luminaire for centrally lighted roundabout of class CE 5

20 Received results and conclusions: Solutions with LED luminaires Class Power [W] Luminaire luminous flux [lm] Number of luminaires/poles СЕ СЕ СЕ СЕ СЕ Solutions with HPSL luminaires Class Power [W] Luminaire luminous flux [lm] Number of luminaires/poles СЕ СЕ СЕ СЕ СЕ The received results show that the installed power reduces with the use of LED luminaires and compared to the solution with HPSL luminaires the biggest differences are for lighting class CE 1 the installed power is 40,9% less. The results for the installed power are also better for lighting classes CE 2, CE 3 and CE 4 when LED luminaires are used. Compared to the solutions with HPSL luminaires it reduces respectively with: 32,5% for СЕ 2; 22,3% for СЕ 3 and 31,3% for СЕ 4. For lighting class CE 5 the installed power with the use of LED luminaire is 4,9% higher but there is a single pole/luminaire and this will reduce significantly the initial costs for building the system as well as the following service activities of the maintenance teams.
