The visit of a Museum is basically a visual experience. For that experience to happen, light is the key factor that contributes to creating the right atmospheres as well as to rendering the artifacts and exhibitions value. Without light, it would be impossible to enjoy, learn and experience the visit of a Museum.
This is a time of revolutionary change in the lighting industry. Solid-state lighting (SSL) systems are on track to achieve lighting efficacies for general lighting in excess of 150 lumens per watt (lm/W) in the not-too-distant future. This is double the typical performance of the ubiquitous linear fluorescent systems in use in commercial spaces today, and 10x the efficacy of the familiar incandescent light bulb, which many countries have regulated out of use in many applications in recent years. The total system performance could be further improved by the addition of smart controls, which include occupancy sensing and daylight harvesting, among other features.
Have you ever tipped back your head and looked up at the immensity of the night sky, clothed with twinkling stars, wandering planets, itinerant comets and the flash of the International Space Station whizzing by? An impressive sight even from the city , if you’re privileged enough to be on top of a volcano in the middle of the Pacific such as Mauna Kea, the garland of the Milky Way and billions of shining stars strewn about it, carelessly, are awe inspiring. Now imagine instead that you took a ride on one of those comets as it was speeding toward the earth or perhaps you’re more conservative and suffering from a touch of motion sickness, imagine you were floating about the cupola of the International Space Station having turned a few somersaults and took a look at our beautiful, blue planet as the sun set, what would you see? Vast expanses of darkness, interspersed with twinkling lights, immense oceans bordered by pulsating city lights. A delicately poised universe, lit up with lights of every kind, incandescent, fluorescent and most recently Light Emitting Diode (LED) lights.
Street lights illuminate the roads we drive on, the pedestrian paths we walk along and the public areas where we gather. This outdoor lighting provides us with safe roads, inviting public areas and enhanced security in our neighborhood, businesses, and city centers. As so many of our modern day achievements, we often don’t think about it, only noticing it when it’s not there.
The way outdoor lighting systems are managed has changed greatly in the past ten years. Traditionally lighting scouting teams were driving through the streets to spot failed lights. Paper maps and files were used to manage the maintenance of the lighting installation. The energy consumption of the lighting installation could often only be estimated. In a time, when cities and road authorities aim to reduce costs, to increase safety, and to protect the environment better – street lighting becomes a key target for further improvements.
Today 1.2 billion people around the world do not have access to electricity. Without light, they resort to using dangerous and unhealthy toxic carbon-emitting kerosene lanterns to extend daily hours to be able to do daily tasks such as cooking and studying. To address this issue, the VELUX Group and the social business Little Sun are collaborating to help bring clean, reliable, and affordable light to off-grid African regions.
