Some sustainable lighting innovations in 2016

By BizLED Bureau

Jan 3, 2017: Energy efficient lighting has seen a number of innovations in 2016, leading to new opportunities for lighting designers to rethink on how to make lighting more sustainable and efficient.

New lighting materials

A number of new sustainable lighting materials emerged in the market in 2016. Graphene, a synthesized material manufactured by the University of Manchester in 2004, entered the market in 2016. Graphene is ultra-light, extremely strong, and very conductive. In 2016, it was integrated as a lighting filament as it is more conductive than silicon and less susceptible to heat. Bulbs using these Graphene filaments are at least 10% more efficient and longer lasting than other bulbs.

Gallium nitride is another material which was used in violet LED (instead of sapphire), invented by Nobel Prize winner Shuji Nakamura, to obtain better colors and more efficiency.

Biophilic lighting design

In 2016, biophilic lighting design became popular. Biophilia is the concept, which means that because human bodies are linked to nature, the lighting should also imitate nature when designing for buildings. It is the best way to optimize health and efficiency. Biophilic lighting uses human connection to the sun to maintain health and protect the circadian rhythms. This type of lighting improves human health, boost productivity, and drastically cut lighting costs.

Low and no-energy bulbs

Some companies innovated some low and no-energy bulbs, which are eco-friendly as well. With the trend of using ‘less power and save energy’ picking up in 2016, UK inventor Malcolm Wright used other devices to power an LED light. His system is called Electrical Energy By-Product Lighting (EEBL), which helps electric bill to remain the same by squeezing more light out of the same watts that were being used.

Professor Daizhong Su and his team at Nottingham Trent University, UK, have developed an eco-friendly light using recycled aluminum and silicone covered wiring to reduce carbon footprint.

Another innovative lamp–iViTi’s ON Lamp—remains lighted even after power cuts as the on-board back-up battery kicks on and remains lighted for several hours. iViTi can also keep track of energy use on the power grid, as a result, you can move to battery use and save electricity.
