What to Consider in Street Lighting Designs?
- 12 Apr 2024
Street lighting plays an important yet often overlooked role in shaping urban environments. As streets serve as public spaces where people interact, lighting design directly impacts how safe, welcoming, and vibrant these areas feel.
Without proper consideration, lighting can be inefficient, uneven, and even hazardous due to excessive glare. However, a well-designed street lighting design tailored to its specific surroundings and needs ensures visibility and optimises aesthetics and energy use. When planning lighting upgrades or new installations, taking time to evaluate certain key factors leads to street lighting solutions that improve public experiences and serve communities best in the long term.
The Crucial Role of Street Lighting
Street lighting serves as an essential infrastructure.
At night, proper street lighting design allows streets to continue facilitating travel, recreation, and social activity. It impacts safety, security, and comfort that encourage using areas throughout the evenings. Optimized designs improve visibility for navigation and emergencies while complementing surroundings.
Poor planning undermines safety perceptions, wastes energy, and delivers unwelcoming tones. Therefore, properly balancing illumination, aesthetics, and efficiency from the outset ensures street design maximises space usability. When it comes to street lighting design, here are the key factors to consider:
1. Luminance Level
Proper luminance is needed to clearly illuminate pathways for safe travel without wasting energy caused by excessive brightness. Evaluating factors like pedestrian activity, traffic volume, and road classification allows for optimising luminance adjustment. For example, busier intersections and vehicle lanes may require higher luminance than calmer sidewalks. Achieving the proper balance between visibility and efficiency requires careful consideration.
2. Luminance Uniformity
Consistent illumination across an entire street or area is vital to real and perceived safety. Without uniform light levels, dark spots are created that could obscure obstacles, surfaces, or potentially dangerous situations. Unlit areas become safety hazards and diminish a sense of security. Proper placement and angling of street lighting design prevent unintended shadows and ensure smooth transitions between the lighting of different structures, like buildings and signs.
3. Glare
Harsh or unshielded light sources can create disabling glare instead of improving visibility as intended. Excessive brightness or uneven distribution from fixtures like exposed bulbs distracts and impairs night vision for drivers, cyclists, and pedestrians. Controlling flexible neon LED strip glare through fully shielded, precisely aimed fixtures minimises discomfort and distraction while maintaining quality illumination across surfaces.
4. Effectiveness: Balancing Cost and Performance
Economic effectiveness is an important aspect to consider in street lighting design as it involves optimising the cost-effectiveness of the lighting system over its lifespan. Here are some factors to consider in achieving economic effectiveness:
- Initial Cost: Evaluate the upfront costs of purchasing and installing street lighting fixtures, poles, wiring, and controls. Compare different lighting technologies, such as LED, HID, or fluorescent, to determine the most cost-effective option considering initial investment and long-term savings.
- Energy Efficiency: Prioritize energy-efficient lighting technologies, such as LED (Light Emitting Diode), which consume less energy compared to traditional lighting sources like HPS (High-Pressure Sodium) or incandescent bulbs. Calculate the potential energy savings over the lifespan of the lighting system to determine its economic viability.
- Maintenance Costs: Consider the ongoing maintenance costs associated with the street lighting system, including lamp replacements, fixture repairs, and cleaning. Choose durable fixtures with long lifespans and minimal maintenance requirements to reduce long-term maintenance costs.
- Life Cycle Cost Analysis (LCCA): Conduct a life cycle cost analysis to evaluate the total cost of ownership of the street lighting system over its expected lifespan. This analysis should include initial costs, energy costs, maintenance costs, and replacement costs to determine the most economically effective option.
5. Surrounding Environment
Existing structures, vegetation, typical activities, and the natural or built landscape influence ideal lighting temperature, illumination direction, and fixture appearance. Warmer or cooler hues, cutoff angles, and compatible contemporary or historic-style fixtures help to forge a unique environment.
6. Aesthetics
Beyond functionality, integrated lighting enhances an area’s aesthetic appeal and encourages community engagement. Attractive, consistent installation and ongoing maintenance help street lights define and reinforce positive neighbourhood character and identity in the long term. A coordinated street lighting design improves visual cohesion and perception of quality.
