Effective street lighting depends on strategic engineering to balance visibility with energy efficiency:
A street lamp (or lamppost) is a raised light source typically mounted on a pole along roads, paths, or medians [3, 8]. Its primary functions are:
A standard LED bulb (approx. 10 watts) running for 12 hours a day consumes very little power, with an estimated daily cost as low as 1.44 cents depending on local utility rates [29]. STREET LAMPS 1.44
Deterring crime through "natural surveillance," as well-lit areas increase the perceived risk of an offender being recognized or caught [7, 21].
Providing clear guidance for nighttime travel in urban and residential areas [5, 19]. 2. Technical Specifications and Design Deterring crime through "natural surveillance
Research consistently shows that improved street lighting leads to a in treated areas compared to unlit control areas [4]. It is particularly effective at reducing property crimes and increasing community pride and cohesion by encouraging more frequent use of public spaces after dark [6, 13].
A general rule is to space poles at 2.5 to 3 times their height (e.g., 30-foot poles should be 75–90 feet apart) to ensure uniform coverage and minimize dark spots [16]. or medians [3
Enhancing visibility for both drivers and pedestrians to reduce traffic accidents [10, 14].
