There was a time when fluorescent lights were dominating the lighting industry. High power consumption, short lifespan and the presence of mercury were the biggest drawbacks of fluorescent bulbs. These pushed us to look for better alternatives and we came up with LED technology. LED lights have completely reformed the lighting industry. Equipped with better tech, energy-saving features, and better cost-in-use parameters, LED lighting products have become the most-preferred lighting solutions among industries, commercial places and households.
While LED lighting products have yet to reach the mass appeal of traditional lighting products, the innovation keeps going and new lighting products keep coming out. In this blog, we will explore the most promising LED lighting products & concepts that will take over the future. Enough said, have a look at 5 revolutionary LED lighting innovations that belong to the future:
OLED Lighting –
OLEDs – short for Organic Light Emitting Diode – are advanced LED lights comprising of carbon-based organic materials that emit light when exposed to electricity. Unlike LEDs, OLEDs generate very little heat making the need for diffusers and heat sinks totally obsolete. OLED lighting is the most popular innovation in the market currently and primarily used in latest smartphones and ultrahigh definition televisions.
OLEDs are different from their predecessors in many ways. They possess flat surface lighting systems which facilitate mounting on glass, plastic, and metal. Their flexibility to transform into any shape is the biggest reason behind the OLED’s growing demand across the world.
Konica Minolta, the Japan-based multi-national technology company, is doing brilliant work in the OLED lighting category.
LI-FI (Light Fidelity)
Founded by Harald Haas, a professor from University of Edinburgh, Li-Fi is very similar to WIFI as they both transmit data electromagnetically. Unlike Wi-Fi, Li-Fi uses light rather than radio waves to transmit wireless data.
To put it simply, Li-Fi makes your light bulb a router. It uses household’s light bulbs to enable data transfer with speed of more than 220 GB per second. Besides a plethora of advantages, Li-Fi has some significant drawbacks as well like the restriction of signals to pass through the walls, security issues with shared internet connection, and total dependence on the light to get uninterrupted wireless internet connectivity.
Nevertheless, Li-Fi has the potential to reform the LED lighting industry for good in the future, especially when smart cities and Internet of Things (IOT) are talk of the town.
Healthy lighting has been making quite a stir lately for its health benefits. These LED lighting products are designed to emit light relative to the visible section of the solar spectrum. Healthy light bulbs mimic sunlight with similar wavelength spectrum.
Since the (CRI) color rendering index of healthy lights is 80 which is considered among the best, healthy light bulbs reflect colours perfectly and as good as sunlight. Multiple studies have revealed that direct exposure to healthy and well-being lights have positive effects on the overall health of human beings.
A study conducted by ASID on its staff to check positive effects of circadian healthy lights made promising revelations. 25% of employees reported a huge improvement in their sleep cycle and overall well-being.
With proven health benefits and huge power saving features, there is no denying the fact that healthy lighting is going to be the most-preferred LED lighting products among households, industries, and corporations in the future.
There are multiple studies which show that the greener areas experience less crime as compared to the other ones. According to another study based on the positive effects of green spaces in workplaces, the corporate employees have shown 15% more productivity in the presence of green houseplants.
Talk about pushing boundaries, a group of scientists from Massachusetts Institute of Technology created plants that glow in the dark. The innovation is something that entire world took notice of. The scientists used specialized nanoparticles in plant leaves for illumination.
The researchers said that this technology will be used to provide low-intensity indoor lighting. After further research, there is a strong possibility that plant powered light technology will be used to transform trees into self-powered street lights.
The science behind it is the enzyme called luciferase, which gives fireflies their glow and co-enzyme A which gives supports for faster reaction activity, are used to create the glowing plants.
LASER lighting is already creating waves in the automotive industry. Actually, they are on the verge of replacing LED lights for better illumination. Experts have speculated that the LASER lighting is the future of LED lighting in the automotive industry. LASER diodes are droop-free and can be combined with phosphors to produce high-quality output with superior lumens per watt.
Since the LASER diode’s efficiency is 10 to 12 times higher than that of LED lamps, they have already been used for developing higher-output headlamps at BMW and AUDI. The full-beam of LASER equipped headlamps on vehicles such as BMW I8, AUDI R8 LMX, and BMW 7 series have a range of up to 600 meters, which is approximately double the distance of LED headlamps.
“Laser diodes are the future of lighting and have compelling advantages over LED” Dr. Shuji Nakamura, the inventor of blue LEDs , said at the LuxLive exhibition in London.
IOT powered lighting
Internet of Things has grown massive over the past decade and big brands like Google, Amazon, and Philips are already capitalizing on it. Smart lighting brings amazing control for business managers as well as homeowners which all add up to it’s growing appeal. From power savings to ease of usage and personalization, a lot can be accomplished through voice, apps and software. No wonder that the international IoT industry will reach $8.9 trillion in 2020.
The future of lighting is every exciting since innovation is happening at a rapid pace and new technologies are emerging very frequently.
