Visit www.lightingindesignmagazine.co.za 2 022 has been a curious year. The after-effects of the pandemic, surging infla tion, supply chain issues, the KwaZulu-Natal floods, Phala Phala, monkeypox, the Russian invasion of Ukraine, the passing of Queen Elizabeth II … it has been a bit of a rollercoaster. Yet business has to go on despite whatever setbacks arise. So, where is the lighting industry going? The LED industry certainly takes the lead when it comes to driving innovation, developing new technologies, and making frequent break throughs. The kind of lighting in our environment influences our physical and emotional state, refines the space, and alters how architecture is perceived. Dim and slight flickering of old fluorescent lamps can lead to corrosive concentration and unrest, whereas spaces with the best lighting evoke positive emotions of happiness and enthusiasm. As architects, designers, and builders are understanding the effects of light on humans, they are increasingly adopting human-centric lighting to help workers become more efficient and productive. LED-based human-centric lighting (HCL) offers many potential advantages in offices and workspaces, increasing the value for occupants in the environments where luminaires are installed. Healthcare facilities are also utilising HCL to add cooler corrector colour temperatures (CCTs) to keep employees alert and warmer CCTs in patient’s rooms to keep individuals in comfort. Educational institutes are adopting LED-based HCL lighting to keep the students alert and at ease. Even aircrafts install LED-based HCL systems to provide passengers with an enhanced flight experience by customising light during flight activities such as boarding, mealtimes, sleep, and to alert passengers as they prepare for landing. The global food system accounts for a quarter of the world’s greenhouse gas emissions. Besides, the expansion of metropolitan hubs is gradually reducing ara ble lands, creating the need for more alternative farming practices such as vertical and indoor farming. Increased efforts towards sustainable agriculture have led to increased indoor farming adoption that utilises less energy, water, and land than traditional farming methods. Using artificial LED lights in horticulture, farmers can either supplement natural daylight or replace it entirely to produce a wealth of ben efits, such as the ability to fine-tune quality and increase yield. LED lights provide just the right amount of light to the plant where it needs it the most and radiate less heat than conventional lighting, which increases yields in dark months of the year. Besides, LEDs provide the right heat-light balance to improve the propagation of vegetables, fruits, leafy greens, herbs, and floriculture crops in a climate-controlled environment. The LED grow lights can help retain the unique properties of crops, enhance flavour, and maintain the nutritional value of the crops. From a business perspective, LED grow lights save the operator much money for the operator since they consume less power, generate less heat, and require less maintenance than HPS lights. High yield from LED grow lights adds to more crop productivity, which contributes to the profitability of the business. As you can see, it is an exciting industry to be in despite the global challenges, and whatever 2023 throws at us, I’m sure the lighting industry will respond with innovation.
