Lamp post with low resonant frequency has conical or telescopic junction between large diameter base and the narrower upper section is less affected by wind power than traditional construction

摘要

The lamp post uses a conical or telescopic junction between the large diameter base and the narrower upper section which supports the lighting assembly. The junction acts as a shock absorber and also reduces the natural resonant frequency of the post. The low resonant frequency means that the post is less affected by wind power than traditional construction.
