Research Abstract |
This research proposes a new street lighting environment which distributes small light sources to blind areas around the street as against the general pole lighting with high intensity light sources. Such a lighting environment was fixed for the first time, and the effect was evaluated. As a result, amounts of luminescence and consumption energy have got smaller than the previous street lighting, and the illuminance level on the street has also become low. The visibility around the street has improved by having installed lights in the vacant lots contiguous to the street. However, the possibility of danger and sense of insecurity originating in darkness were pointed out by the pedestrian.
