LIGHTING ENGINEERS MUST BECOME ARCHITECTS OF THE NIGHT

The author argues that much street lighting is unnecessarily drab and monotonous. The new British standard BS 5489 part 2 attempts to combine the luminaire light distribution, mounting height and effective road width approach with a required level of luminance which will give more importance to the lighting effect. Street lighting needs a different approach from basic road lighting if the daytime appearance of street furniture is to be acceptable. At present, there are three or four types of coloured light sources that are economically acceptable. High pressure mercury lamps are good at highlighting trees or grassed areas and the low pressure sodium lamp can be used to floodlight features. However the use of a monochromatic source for general lighting must be questioned. Major junctions and central island markers can often be designed as a useful colour contrast. It is also important to provide as much light for people as for the motorist. (TRRL)
