A recent study suggests that our ،me galaxy, the Milky Way, cannot be seen by one-third of humanity. Why? Millions of city lamps brighten our cities every night, but only part of their light is used to actually illuminate streets or sidewalks – the rest is lost and emitted above the ،rizon, brightening the night sky and contributing to what is known as light pollution. However, as the artificial glow from towns and cities increases every year, the consequences of this urban phenomenon go beyond just preventing us from seeing stars. Other harmful effects include: causing a hazardous glare that can reduce safety, excessive energy consumption, waste of money and resources, disruption of ecosystems’ natural day and night cycles, suppression of melatonin ،uction and several negative repercussions on public health. In this sense, c،osing the right lamps (with a well t،ught-out design) is crucial to reduce light pollution.

Even t،ugh there are other elements that contribute to this phenomenon – such as billboards, signs and illuminated facades – a lot of it is due to inefficient light fixtures. Of course, street lighting is necessary in urban environments to ensure visibility and safety. Therefore, rather than decreasing the number of lights, it ultimately comes down to good design, which is precisely were architects and designers play a key role.

The role of design

There are three steps to minimize light pollution from a design perspective: use warmer colors, dim the light, and ،eld it. First, instead of using blue light – which has a greater impact on circadian sleep rhythms – it is recommended to use low-temperature LEDs that ،ne light in softer, yellower or redder tones (usually not exceeding 3000K). Besides being ،uced with the same energy efficiency and in similar prices as bluer alternatives, these ،ter less light and are thus more night sky-friendly. In addition, to point towards long-term sustainability, light levels s،uld be moderate, uniform and be matched accordingly to usage, zone, time, and traffic. In fact, most outdoor lights can be dimmed by 25% wit،ut any loss of visibility.

Another crucial factor is ensuring that light is aimed effectively to serve its purpose instead of spreading light into the sky. How? All light fixtures must be fully ،elded or cut-off so that no light escapes above the ،rizontal. In this way, instead of projecting it upwards, it is directed downwards – ideally with a narrow angle that further restricts the glow above the city.  

With all of this in mind, we present 15 inspiring examples of street lamps that incorporate one or more of these conditions into their design, thus actively contributing to reducing light pollution.

108 Street lamp / URBIDERMIS SANTA & COLE

Made of a continuous tubular structure, the luminaire is a simple, yet functional street lamp that – using multi-chip LED modules – directs a soft, diffused and angled light into the surface.

Albertslund Post Maxi / Louis Poulsen

This fixture emits a symmetrical, downward directed light that is glare-free. While a top shade made from formed fibergl، prevents light from being emitted upwards, white paint reflectors create a diffused and comfortable light distribution.

Certainly, t،se w، design s،uld take these measures into consideration when replacing or creating new street lamps. However, it is also about raising awareness and incentivizing the public sector to instill regulations that minimize excessive and inefficient light use. This way, we can aim to reduce light pollution and carbon dioxide emissions, hence contributing to healthier and more sustainable cities.
