Electricity forms the base of our modern life. Although its demand is ever increasing, its supply can’t match it. In addition, a considerable portion of the electricity that we use comes from non-renewable sources. Therefore, it becomes necessary for us to find sustainable technologies that not only help us save money but the environment too. Amongst all the environment-related schemes that nations are carrying out throughout the world, governments play a very important role. The least the countries can do to go green is they can opt for eco-friendly streetlights.
20 – Eco friendly streetlights that show us the green way
Nowadays, there is a rising demand for energy. Moreover, its supply is also declining. This is making product manufacturers and designers come up with sustainable alternatives. These help us save energy as most of them run on renewable sources of energy. The street lighting industry is also witnessing a change. Many manufacturers are unveiling next-gen solar-powered street lights and designers are coming up with even better lighting solutions for the future. Boosting this green trend, here are 20 sustainable street lighting systems that can make streets green and safe.
1. Solar Powered Invisible Streetlight
Designed by Johgoh Lee, the Invisible Streetlight is a solar powered street light. It imitates leaves and easily hides among natural plants on the sides of streets. Comprising double injection of silicon, aluminum and a photo capacitor, these sustainable lights keep glowing all night long.
2. Prisma Street Light
The Prisma Street Light by designer Agustin Otegui projects three light beams in different directions. It has 360 degrees of colored light with varying intensities. These can be radiated from the LED sphere. Furthermore, solar panels on the sides also charge the lights during the day and provide light at night. Moreover, the electromagnetic glass shifts from transparent to reflective and you can redirect the light when you don’t need one of the sides. This results in adequate use of power supply.
3. Solar Trees
Conceptualized by designers over at Vinaccia Integral Design, the Solar Tree is an innovative street lighting system that gets powered by renewable solar energy. The tree-shaped structures have six branches, each of which has monocrystalline silicon solar cells that generate up to 100W of clean electrical power. In addition, the stored energy is supplied to a 48W LED lamp that has brightness equaling an ordinary 400W halogen lamp.
4. Solar-powered Gotham Lamp
3XN designed sustainable LED luminaires for Bella Center in Copenhagen. Dubbed Gotham, the street lamps are powered by solar energy which is harvested by PV modules. The modules generate more energy than what is required by the lamps.
5. LED Lantern Solar Light
Designed by Vinaccia Integral Design, the LED Lantern Solar Light helps illuminate streets with renewable energy. The lights are to be crafted in aluminum with monocrystalline silicon solar panels. These can generate up to 100W of green power. Moreover, the energy is stored in batteries. After dark energy is released to fuel LED headlamps which consume up to 48W of power for the same amount of illuminating power as a 500W halogen lamp.
6. Luceplan Sky
The Luceplan Sky by Alfredo Häberli relies on the energy of the sun to illuminate the streets after dark. The PV panels resting on top of the lights charge batteries during the daytime. As night falls, this power up the LEDs to release intense and prolonged lighting in the area.
7. Ross Lovegrove’s Solar Tree
British designer Ross Lovegrove designed the Solar Tree, an innovative street lighting system that relies on renewable energy. The idea was to bring art and light to the Ringtrasse and Lovegrove came up with the concept of solar tree, made with the modern technology of pipe bending.
The Embryo Street Lighting concept by designer Harsha Vardhan looks completely practical and effective. Inspired by a living sprout, the Embryo not only generates electricity for illumination but for other uses as well. The flexible photovoltaic cell on the top of the hood-like roof and an included wind turbine harnesses renewable energy that will not only supply power to the lamp itself, but the remaining energy can be stored in a battery contained at the bottom and used for other purposes.
9. Sharp’s Solar Powered LED Street Light
Sharp LN-LW3A1 is a solar-powered LED street light combines a Seismic Motion Sensor that detects the occurrence of a major earthquake measuring 5 or greater while delivering full brightness during nighttime hours for two days. With a lifetime of 10 years, the zero-maintenance street light certainly seems like a lamp for a greener future.
10. Night Owl
Industrial designer Edan Kurzwell has develop the Night Owl lighting system. It is illuminated via high-output LED clusters. These rely on batteries which charge by large flexible polymer solar films on the top of the lights. The lights would also be hardwired into the city’s power grid. This would return any additional solar energy back to the city. Furthermore, it would also help to draw minimal charging power during long winters, or long periods of time without sunlight.
The Seagull is a solar and wind-powered spinning streetlight that stores renewable energy in a battery at the base of the light pole. Solar panels takes the center stage during day time and the spinning wind turbines are for the night.
The SonUmbra has been designed by Loop.pH as a unique interactive solar-powered tree lighting system. The structure comes with strands of light-emitting fabric woven into a lucent web of branches. The SonUmbra gets powered from a PV-equipped canopy that harnesses solar energy during the day and stored it in onboard batteries to light the tree up after dark.
13. Trash-powered Streetlamp
Industrial designer Haneum Lee has come up with a concept lighting system that not only reduces the energy demands but also composts food waste. The lamppost composts trash and uses the methane, which releases as a byproduct to fuel the lights. In addition, the concept lamp allows users to throw their organic waste into a wastebasket, which further recycles it for the desired energy.
14. Nature Power Light Your Road
Industrial designers Zhou Qian and Tao Ma have tried to bring wind and solar energy generating techniques together in a concept streetlight dubbed Nature Power Light Your Road. The system comes in the form of a flower, with the petals equipped with solar panels and a wind turbine as well. Furthermore, whatever energy the combination generates, it stores that in onboard batteries. Afterward, it relays it to a set of LED lights after dark.
15. Light Tree
The Light Tree by designer Omar I. Huerta Cardoso has been crafted like a tree with nanotube solar cells that provide unique aesthetics aside from great functionality. The concept combines hydroponic techniques with the latest solar cell technology. In addition, it features water inside to efficiently conduct the light. This light is generated by a range of ultra-bright LEDs placed in the base. The water feeds the seeds towards the top of the tree.
16. Hybrid Wind and Solar Powered Street Lamp
These hybrid streetlamps by Urban Green Energy consist of a solar array topped with a wind turbine. Furthermore, the generators churn out up to 380W of electrical power to keep these lamps glowing through the night.
17. Flow Bamboo Lighting
The Flow by IGenDesign is a public lighting system with a difference that harnesses sustainable materials and energy to light the bleak nights at secluded places. Featuring a structure finished in bamboo that supports LEDs, wires and the dynamo. Furthermore, the self-maintaining light works on the principle of vertical wind turbine and seizes the wind from all directions to power the lamp at night.
18. Turbine Light
Designed by TAK Studio, the Turbine Light produces energy from air turbulence caused by passing traffic. The contraption or conception channelizes the electrical energy to illuminate the way of the passing vehicles.
19. Light Blossom
Designed by Philips, the Light Blossom lighting solution will give you LED-illuminated streets with the power of the sun and the wind. The lights that come with petals keep on transforming and changing their position to get the most out of the sun and wind throughout the day. In addition, as night falls, these lights get into a “stand-by” mode, and keep emitting the minimum light required for safety. However, as someone crosses the street below, the proximity sensors mounted on the lights enable the lights to come out of the stand-by mode and shower the street with the maximum light that can be offered.
20. Mawaridoro Lamp
Toshihiko Suzuki Architects and Associates have developed the Mawaridoro wind-powered lighting system that uses wind speeds of 1.5m/s to rotate a lampshade measuring 30 cm in diameter. The energy generated is directly used to illuminate the LEDs. Excessive power is stored in a nickel hydride battery for quiet evenings.
