Guidance on the Application of Adaptive

Lighting within the Public Realm

Ultra-Efficient Lighting (UEL)

The adaptive lighting approach will essentially look to help enable you to apply the principles of Ultra-Efficient Lighting (UEL) which is defined as:

“Providing the • right light, in the • right place at the • right time and controlled by the right system”.

#ILPSummit

BS5489-1:2013 for the five step design process, the steps being as follows:

Step 1 Select lighting classStep 2 Risk assessmentStep 3 Adjust lighting classStep 4 Consider S/P ratioStep 5 Consider adaptive lighting

#ILPSummit

Adjusting the lighting class

The British and European Standards allow illumination levels to be varied depending upon the category of road and its usage. Therefore illumination levels could be reduced when traffic flows are lower.

Lighting could also be increased as a crime reduction measure, say outside night clubs for a defined period after they close.

#ILPSummit

What is adaptive lighting?

The term used do define the operation of the lighting during the periods of darkness. It includes:• Compensation for design maintenance factors• Trimming• Adjusting the lighting class based upon highway/area use or the

tasks being undertaken– For highways this may be a reduction in lighting

class– For areas around entertainment venues this may

be an increase in lighting class when such venues close

• Part-night lighting or Switch off.#ILPSummit

Looking at Adaptive Lighting

Compensation for design maintenance factors is where the maintenance factor is simply designed out through the application of constant light output across the design maintained period

“Trimming” is where currently the majority of public lighting switches on when ambient light levels fall to 70lux and switches off when the ambient level rises to 35lux. This was a standard approach that allows time for lamps to ‘warm up’ and reach their required operational output.
