Why Are Most Street Lights In Cities Yellow
Urban street lights are mostly yellow in colour, which is the result of multiple factors such as optical properties, human vision, historical technology and cost-effectiveness. With its advantages of long wavelength and low glare, yellow light plays an important role in ensuring road safety and reducing operating costs. However, with the rise of new technologies such as solar streetlights, urban lighting is ushering in new changes. In the future, intelligent, personalised, green and low-carbon lighting will become the mainstream, adding more colour and vitality to the city nightscape, while also making city life safer, more comfortable and better.
