The lighting revolution in summary

According to Signify CEO for Africa, Tamer Abol Ghar, the evolution of lighting was off to a slow start some 140 years ago, with the invention of the light bulb; for some 120 years, the only developments in lighting were variants on the shape and size of light bulbs.

This was followed by the quest for energy efficiency and the advent of LED technology, with its 80% efficiency. He says the worldwide lighting market, which traditionally had only four or five players, is currently changing again with the influx of ICT companies in the lighting industry.

This influx, together with fast-changing technology, makes it difficult to enter today’s market. At the beginning of the LED revolution, the world lighting market aimed to achieve a 75% LED installed base by 2020 but that figure will be reached this year.

The next phase, says Ghar, will be internet-based lighting and lighting control, signifying a shift to digitalisation. Yet another new concept seeing the light at present involves integrating lighting with other technologies such as security.

In retail, lighting will be used for indoor positioning with an accuracy of up to 5 cm. He says that, in the Middle East, this approach has increased turnover in retail by up to 30% as it enables marketing in the shop front.

A major advantage of connected lighting in cities is that it helps to prevent theft and simplifies maintenance. Connected lighting also allows municipalities to control electricity theft as, in the case of street lighting, the utility can “see” every light pole.

Connected lighting also reduces maintenance cost and maintenance personnel are forewarned of luminaire failure. Street lighting can further be dimmed or brightened, depending on traffic volumes. This technology is already installed in countries such as Morocco.
