Lighting is one of the most important factors that affects our everyday lives. It illuminates all we do, from work to play to rest. Over the last few decades, lighting has undergone a huge transition from incandescent or fluorescent bulbs to LEDs (light-emitting diodes). 

LEDs use less energy and thus cost less to operate. They also have a longer lifespan, versatile directionality and durability as far as maintenance is concerned. LED has also been shown to help improve our well being. 

There are constantly new advancements in the lighting industry. Here are 5 of the main recent breakthroughs. 

1. Li-Fi Lighting

Li-Fi is short for light fidelity, and it's changing the way data is transmitted. This is a wireless optical technology that allows devices to network and transmit data. This is an alternative to Wi-Fi, which uses radio frequency. Li-Fi uses light to transmit data and has 10,000 times the frequency spectrum of radio. 

Li-Fi cannot interfere with sensitive equipment, like electronics or machines, as Wi-Fi can. Locations where Wi-Fi may be weak or inaccessible could also be reached by Li-Fi, making it more versatile.  

Li-Fi is also more secure and ideal for military zones, government buildings or financial institutions because access to the network requires a clear line of sight. It cannot pass through solid walls, adding an extra layer of security. 

2. Human-Centric Lighting

We are always looking for the right type of lighting for our scenario--brighter lights in the workspace, lower lights when relaxing, etc. Recent studies on the correlation between light and levels of wellbeing have found that the type of lighting we're exposed to affects our sight, safety and overall mood. It also affects our sleep, alertness and cognitive performance. 

"Human-centric" lighting refers to lighting created specifically to support people's general health and performance by utilizing the visual, biological and emotional benefits of light. 

3. LED Lighting and IoT

The Internet of Things (IoT) has infiltrated every area of our everyday lives, and lighting is no exception. LED lighting fixtures that are IoT-ready can be connected to network devices for ease of use. This allows the consumer to program their fixtures and devices to operate how and when they want. With a few clicks, your lighting can be set up to perform exactly to your needs. 

4. Smart LED Lights in Shopping

New lighting technology is taking the dressing room by storm. Retailers are installing Pi-LED technology in the fitting room that allows the customer to see themselves in more realistic lighting. Shoppers get a simulated experience of when they are going to use the garment in real life. There is a control panel that allows the shopper to use varying color temperatures to mimic real life, ensuring the customer will get the best experience in choosing the right item for themselves. 

5. Non-Visible LED 

Non-visible lighting products, like UV and IR LED are in use in the aesthetic, commercial, industrial and health sectors. UV light is used in curing and drying of materials, air and water sterilization, disinfection and other forms of hygiene control. IR LEDs are used in mobile applications, remotes and sensors in security cameras. 

New ideas will always present themselves and continue to push the bounds of what we know as lighting. We've come a long ways from the original incandescent bulb, and who knows what the future will hold in lighting technology!
