What are the requirements of street lighting?
Main Factors in the Street Lighting Design Scheme
- Luminance Level Should be Proper.
- Luminance Uniformity must be Achieved.
- Degree of Glare Llimitation is always taken into Design Scheme.
- Lamp Spectra for Visual Sharpness depends on the Proper Luminaries.
- Effectiveness of Visual Guidance is also an important factor.
What is the standard lux level for street lighting?
Required Illumination Level for Street Light (L) is 6.46 Lux per Square Meter.
What are the general principles that are usually employed in the design of street lighting?
Diffusion Principle The diffusing nature of street or road surface causes the reflection of a certain portion of incident light in the direction of the observer which makes the surface of the road appear brighter to the observer. In the case of the diffusion principle, the lamps are filled with suitable reflectors.
How are street lights measured?
Typical Calculation of Road Lighting:
- Street illumination level in Lux (E)=(Al x (cu x mf)) / (w x d)
- E = The illumination in Lux.
- w = Width of the roadway.
- d = Distance between luminaries.
- cu = Coefficient of utilization.
- Al = Average lumens, Al = (E x w x d) / Cu x mf.
- The typical value of Al is.
- 20500 lumens for 400 watts.
Is standard for street lighting?
Street lighting in India is classified in the Indian Standard (BIS, 1981), based on the traffic density of the road (see Table 1). Based on the classification in the code, the local engineer matches the category of road, and designs and provides installation specifications for the street lighting system.
What is the distance between two street lights?
Technically, the distance between two street lamps should be 29 meters. This is defined by calculations of pole heights and other factors. Intention of keeping a standard distance is to maintain good illumination on streets.
What is the spacing of street lights?
The spacing between two light poles should be roughly 2.5–3 times the height of the pole. Shorter light poles should be installed at closer intervals. The density, speed of travel, and the type of light source along a corridor will also determine the ideal height and spacing.
