1.1 Background of the Study

Street lighting plays a crucial role in urban and suburban environments by enhancing visibility, promoting safety, and contributing to the overall aesthetics of public spaces. Properly illuminated streets are essential for pedestrian and vehicular safety, crime prevention, and community well-being. The evolution of street lighting technologies from traditional incandescent to LED lights has significantly impacted energy efficiency and maintenance costs.

Street lighting is an integral component of urban and suburban infrastructure, playing a multifaceted role beyond mere illumination. It serves as a cornerstone for enhancing visibility, ensuring safety, and shaping the overall aesthetic appeal of public spaces. The significance of properly illuminated streets extends far beyond mere functional utility; it profoundly influences community dynamics, economic vitality, and quality of life for residents.

The primary function of street lighting is to provide adequate illumination that facilitates safe navigation for pedestrians, cyclists, and motorists, especially during nighttime hours. Well-lit streets enhance visibility, reducing the likelihood of accidents caused by obscured obstacles or unclear road markings. This visibility is critical in urban settings where densely packed buildings and intricate road networks can obscure natural light sources.

Effective street lighting not only improves visibility but also fosters a sense of security among residents and visitors. Illuminated public spaces create a perception of safety by reducing the fear of crime and enhancing situational awareness. Studies have shown that well-lit environments promote a sense of community ownership, encouraging individuals to engage in outdoor activities and nighttime commerce without fear of personal safety.

Beyond its functional role in safety and visibility, street lighting contributes significantly to the aesthetic appeal and overall ambiance of urban and suburban landscapes. Thoughtfully designed lighting schemes can accentuate architectural features, highlight historical landmarks, and create inviting atmospheres conducive to social interactions and cultural activities. Lighting designers often employ techniques such as focal lighting, silhouetting, and shadowing to enhance visual interest and create memorable nighttime experiences for
