The Story of LEDs
Many innovations in lighting in recent years can be traced back to the LED industry. In 2014, the three scientists who invented the original blue led, greatly known for its efficiency, won the Nobel Prize in Physics.
Accordingly, the United Nations famously dubbed 2015 as the Year of Light.
The purpose was to raise awareness and encourage the shift from traditional light bulbs towards a more promising future, where LED lights would make up the majority of the market.
With this level of international recognition, we think LED lighting has reached its pinnacle, but in reality, the future seems to be even more promising. The development of LED technology is far from done and as such it’s becoming more and more important to businesses and consumers alike.
Globally, LED lights already constitute about half of all light sources. Needless to say this is a tremendous achievement, and according to researchers, by 2030 approximately 87% of all light sources could be LEDs.
A big part of why LED lighting is taking over the global market can be credited to just how more commercially viable they are.
LED lights have far lower energy costs, a much longer lifespan and can be used for all general applications, providing a better quality of light.
Another reason for the swift rise in market share and the projected increase is the constant development and research that is taking place regarding LED lights.
The applications and features of LED lights are continuously growing and expanding.
The improvement of the lumen density (measuring unit for brightness) of LED lights have made LEDs commercially attractive with new potential uses, such as for lighting bridges, stadiums, and other mega structures or spaces.
And with improving LED technology, manufacturing and processing are developing to make the fixtures more affordable to the average consumer or business.
While it’s true that the LED market is rapidly growing, most Australians don’t demand anything fancy from their lights, they often require a simple on/off operation.
However, this basic view of light is changing, and it’s changing fast.
One of the main reasons researchers believe LEDs will dominate the market in the near future is the constant development of this technology.
LED lights no longer follow a basic on/off scenario and are no longer operated solely from switches; they need to be intelligent and efficient. As Steve Kennelly, a senior manager for lighting and medical at Microchip Technology inc. stated
“Being able to adjust the light… not only the brightness but the colour as well… is very important.
Consumers worldwide expect networking capabilities, to allow their lights to communicate with each other.”
Device connectivity is a fast-paced and rapidly growing technology sector, covering a wide range of devices from cameras, street lights, fridges, automobiles, machine vision systems – they all are following the same trend.
Even in the medical industry, physicians appreciate the freedom to manipulate the brightness and change the colour of their lights. The possibilities are endless for businesses and consumers alike.
- LED lights have longer lifespans. They can last as long as 100 000 hours, approximately equivalent to 30 years, without malfunctioning.
- LED lights save greatly on energy consumption and consecutive power costs, saving up to 90% in energy costs.
- LED lights offer a wide range of features for customers like dimming capabilities, changing light colour, remote control.
- LED is a more eco-friendly option.
Beyond Simple On&Off
The only light type that has the potential to satisfy a growing customer demand of going beyond on&off is an LED lighting system.
As innovation thrives based on demand, hardware and software engineers are developing measures and technologies to improve the existing technology of LED lights, to introduce new features and to even develop a new breed of LED drivers.
Applied, installed and operated for years, industrial LED lighting systems have proven the extent of their efficiency and benefits compared to traditional options.
With expected savings as high as 90% in costs, companies can save thousands of dollars each year when using LED lights. And when these LED lights are connected in a smart LED system, the benefits keep on growing.
Besides bottom-line dollar and cent savings, intelligent or smart LED systems can have an immense impact on production efficiency, sustainability and massively contribute to overall facility performance.
Human-centric LED lighting refers to the consumers and businesses using LED technology to create the most effective and desirable environment for themselves.
The most straightforward measure to achieve this environment is through colour changing LEDs. LED light is often a better option due to the broader quality of light and smoother colour spectrum, which is closer to that of the sun than other artificial lights.
Ultimately, installing LED lights that can change colour and smart LED systems to automate this process, consumers can have more blue light during the day, and more warm light during the later hours, simulating natural light from the sun.
Researchers correlate exposure to natural-like colours to better mental states and increased productivity.
Another significant measure to develop effective and desirable environments is the dimming feature and occupancy sensing capability. Not only can LEDs change colour, but they can also be dimmed, resulting in a smoother and better flow alongside natural light.
Occupancy sensors, generally fitted with motion or heat sensing technology, are essential to reduce unnecessary operation of lights and ultimately, unnecessary power consumption.
This measure is not only convenient and cost efficient, but also great for the environment.
This term refers to the ever-expanding range of devices that support internet connectivity, and can communicate via the internet.
This connectivity simplifies and automates the much-needed process of controlling large quantities of lights and complex spaces in simple control structures.
LiFi is the most recent and industry-changing concept in lighting.
The basic concept of LiFi is the use of lights rather than radio waves to transfer data, with proven transfer speeds up to 100 times faster! The Nobel Prize winner in 2014, Shuji Nakamura has named Li-Fi, “the next step in LED technology”
With ongoing research and development in the field, the LED light industry is expected to grow and expand with more advanced technology and within wider and broader sectors, paving the way for a very bright future of LED, in Australia and globally.
