The main purpose of the lighting is to create safety, security, and accessibility, which together with an attractive visual environment helps to encourage citizens’ use of the public space and improve both cultural and business revenue impact for the users. One performance measure of post tops luminaires is maximum pole-to-pole spacing to maintain a minimum foot-candle level at the ground level. These spacing values are provided as a guide to Louis Poulsen post top luminaires.
Wind loading is an important consideration in determining the correct pole design that will safely support the mounted post top luminaires. Wind load evaluation estimates the forces applied to a pole when winds push against the mounted post top luminaire. A pole’s strength is determined by its specifications including material, height, and cross section geometry. The pole’s strength should exceed the estimated wind loads by a certain safety margin to be considered safe to use.
