LED lighting technology has transformed how we illuminate our world, from street lights to business signage and vehicle indicators. It’s a more efficient, durable, and low-maintenance alternative to traditional lighting. LEDs use less energy while lasting much longer.
Despite its widespread use, many people don’t fully understand how versatile LED lighting technology is. Here are eight fascinating ways LEDs are used in various industries today.
One of the most innovative uses of LED lighting technology is in Li-Fi, which transmits data via light waves. Harald Haas introduced this idea at TEDGlobal in 2011. Unlike Wi-Fi, which uses radio waves, Li-Fi transfers data by subtly fluctuating LED lights. This allows data speeds of up to 224 Gbps—much faster than current Wi-Fi technology.
Li-Fi also offers enhanced security. Light waves can’t penetrate walls, making it harder for outsiders to intercept data. Although Li-Fi requires a clear line of sight, it’s ideal for places prone to interference, such as hospitals and aircraft.
LED lighting technology is widely used in hospitals and medical facilities. Tunable LEDs help regulate circadian rhythms for patients and staff. Beyond lighting, LEDs are used in Photobiomodulation Therapy (PBMT), a treatment that reduces inflammation and speeds recovery after surgeries or injuries.
PBMT works by decreasing nerve sensitivity and stimulating skin health through increased collagen production. Both blue and red LED lights are used to treat various skin conditions, including cancer, acne, and wound healing.
LED lighting technology benefits the environment by using less energy than traditional lighting. LEDs convert up to 90% of the energy they consume into light, reducing overall electricity usage. They also contain no toxic materials, such as mercury, making them safer for disposal and recycling.
LED bulbs last between 25,000 and 50,000 hours, far outlasting incandescent and fluorescent bulbs. This longevity reduces waste, further benefiting the environment.
LED lighting technology plays a vital role in forensic science. Forensic experts use LEDs to illuminate crime scenes with specific light wavelengths, making it easier to spot blood, bodily fluids, or fibres. Investigators also use LEDs to enhance fingerprints and detect document forgery.
The ability to produce different wavelengths makes LEDs indispensable for forensic analysis. Whether detecting bodily fluids or improving fingerprint visibility, LEDs help investigators uncover hidden evidence.
The temperature of LED light plays a significant role in its performance. Measured in Kelvins (K), it influences how we perceive the light's brightness and warmth. Warm white (2700K-3000K) creates a cosy atmosphere, ideal for homes. Cool white (5000K-6500K) simulates natural daylight, making it perfect for industrial settings.
Choosing the correct LED temperature can transform the lighting experience in any setting, from a calm living room to a high-energy workspace.
Underwater environments benefit from the energy efficiency and durability of LED lighting technology. LEDs provide reliable illumination for divers, aquariums, and marine researchers. Unlike other lighting options, LEDs resist shock and vibration, ensuring reliable performance underwater.
LEDs also help detect pollutants. When specific wavelengths of LED light hit certain substances, they fluoresce, allowing scientists to monitor water quality more effectively.
LED lighting technology plays a crucial role in food preservation. LEDs can kill harmful microorganisms by emitting light at specific wavelengths. Blue and violet LEDs target bacteria, while UV LEDs combat both bacteria and fungi.
LEDs are widely used in food storage and processing to keep products fresh. Since they emit very little heat, they don't contribute to food spoilage or contamination. Their efficiency and long lifespan make them an excellent choice for food safety.
NASA has turned to LED lighting technology to grow plants in space. LEDs provide the exact wavelengths of light plants need for photosynthesis. They also consume less power and emit less heat than traditional lighting, making them ideal for the space station's closed environment.
NASA’s success with LED lights has major implications for future space missions. In addition to providing food, growing plants under LEDs can help produce oxygen and filter CO2 for long-term missions.
