Mr. Zheng Zhaoxiong, Senior Marketing Director of ON Semiconductor’s Applications Division, believes that "Intelligent LED Lighting" — combining sensing, detection, intelligence, communication, and control — will see significant growth within the next one to five years. With its strong expertise in industrial applications, ON Semiconductor is uniquely positioned to support the development of the "smart lighting" market.
The level of intelligence in LED lighting systems is a key concern. While LED lighting already reduces energy consumption and maintenance costs, intelligent designs can further enhance performance by improving efficiency per watt and lowering long-term operational expenses. Energy measurement, ambient light detection, and communication form the foundation of smart LED lighting: energy measurement ensures system health and provides energy usage data; ambient light detection minimizes actual lighting time, saving energy and extending the life of LEDs; and communication connects each light source for maintenance, identification, and system coordination. This article will explore how each component of the circuit impacts the overall system.
Introduction
Imagine running a marathon on a hot, hazy day. Every bit of energy saved early on can make a huge difference in the final outcome. By the halfway mark, it often feels like you've already won. The leaders seem unstoppable, able to run farther with less effort, remaining calm and composed under pressure. But can they maintain their pace in the second half? Talent and potential are present in every competitive athlete, but true success requires tapping into that potential and adapting to changing conditions. Time and strategy will ultimately decide who crosses the finish line first.
Now, you might be wondering, “What does this have to do with LEDs? Are you really talking about the right topic?†I believe so. Just as a strong runner leads the pack in a marathon, LEDs are leading the way in energy-efficient lighting. Compared to traditional incandescent and fluorescent lights, LEDs offer major technical advantages: lower energy use, longer lifespan, and better control over color and direction.
It is estimated that U.S. energy consumption in 2010 accounted for 19% of electricity, and by 2030, annual lighting energy use is expected to reach 767 TWh. For our marathon leader, this is a huge opportunity! By 2030, LED lighting could reduce power consumption by 25%. Plus, since LEDs last five times longer than other lighting solutions and contain no harmful substances, they can significantly reduce solid waste. LEDs may only need replacing during building renovations. Moreover, the ability to fine-tune colors using red, green, and blue (RGB) LEDs opens up new creative possibilities. The ultimate use of LEDs will go beyond just lighting spaces — they will become more integrated into modern designs and installations.
LED Intelligence – The Key to Winning the Race
How can LEDs reach their full potential? There's no doubt that cost remains a major challenge. Currently, LEDs are much more expensive than existing lighting options. Energy efficiency alone may not be enough to convince price-sensitive consumers and businesses to pay a premium. While mass production may eventually bring down prices, it's unclear whether the cost reduction will meet user expectations. These issues are beyond the scope of this article. If you walk into two hardware stores and try to find the same LED lights, it might be difficult. Many retailers don’t carry enough stock to attract sparse customers. Why? It comes down to pricing and inventory turnover. So, what does this mean for engineers and innovators? How can we unlock the potential of LED lighting and win this marathon?
By giving LEDs a "brain," making them smart, and equipping them with eyes, sensors, and other functions. Designing advanced semiconductor materials for lighting can optimize energy efficiency, extend the life of the lighting system, and reduce maintenance costs. This will help LEDs perform consistently throughout the entire race, stay strong until the end, and win the game through smart design.
