The degree of intelligence of LED lighting systems is a concern. LED lighting can reduce energy consumption and maintenance costs, while intelligent LED lighting design can further improve system performance in two ways; get better performance per watt and reduce long-term operating costs. Energy measurement, ambient light detection and communication are the basis of intelligent LED lighting design; energy measurement provides healthy operation and energy consumption information of the system; ambient light detection can reduce the actual lighting time of LEDs, save energy and extend diode life; communication function will Each light source is connected together for maintenance identification and system level coordination. This article will explore the impact of each part of the circuit on the overall system. introduction Imagine a marathon in hot, hazy weather, saving a little bit of body consumption, which is crucial to the outcome of the game. Usually, when the schedule is less than half, it seems that you have already won the game. The front runners seem to be unsurpassed because these players can run farther with less physical energy. The front runners are radiant and radiant, and they remain calm and in good shape during the heat and competition. However, can these players really keep pace in the second half of the game and continue to lead? Among the well-trained and fiercely competitive athletes, talent and potential can only be played. To be successful, you need to consume huge potential on the road. Can the current leader be able to tap the potential, apply strategies, respond to various natural environments, and finally get what they want? Time and wisdom will explain everything. Now, you might ask me: "What does the marathon have to do with LEDs? Do you really know what you are talking about?" I think so. Just as a strong player leads the marathon, LEDs are far ahead in the field of energy-efficient lighting. Compared to incandescent and fluorescent lighting, LEDs have the main technical advantage of lower energy consumption, longer life, and better control of lighting color and direction. According to estimates, the US energy consumption in 2010 accounted for 19% of electricity. As of 2030, the annual lighting energy consumption will reach 767 TWh. For our special marathon leader, this is a good opportunity! By 2030, LED lighting can reduce power consumption by 25%. In addition, since the life of LEDs is five times longer than other lighting solutions and does not contain harmful substances, LEDs can reduce solid waste and types formed by illumination. It may even be necessary to replace the LEDs, but only when the building is being remodeled. Not only that, but the ability to fine-tune colors with red, green, and blue (RGB) LEDs also provides new opportunities for quality and creativity. The ultimate use of LEDs will not only be limited to space lighting, but will be more suitable for new styles and installations. LED intelligence - the key to winning the game How will LEDs reach their great potential? There is no doubt that the first obstacle is the price. The current cost of LEDs is much higher than existing lighting solutions. Energy efficiency is often not enough to convince price-sensitive companies and consumers to buy more expensive products. Over time, large-scale production may lower prices, but can the cost be lowered enough and the price reduction rate meets user expectations? These are all uncertain factors and are open to question. Of course, these issues are beyond the scope of this article. If we just look for two hardware stores and try to find the same LED lights, this may be very difficult. Many retailers don't have enough varieties or quantities of stock just to attract consumers who are sparse. Why? This involves price and inventory turnover. So what does this mean for us engineers and innovators? How do we make LED lighting reach its potential? How to win this marathon? If we give the LED "mind" to make it smart, put these eyes on the eyes, throat, counting and other functions. Designing valuable semiconductor materials in the field of lighting will optimize energy efficiency, extend lighting life, and reduce maintenance costs. This will help the LED run a complete schedule, stick to the end, and win the game with wisdom. Key elements of LED intelligence Ambient light detection, communication and energy measurement are key elements of an intelligent lighting system. Ambient light detection allows the light to be dimmed when other sources have provided sufficient illumination; in addition, the color of the advanced RGB LED illumination system can be adjusted by detecting the color of the ambient light. The communication function allows remote control and connects small, large lighting units into a central network. Energy measurement accurately calculates the power consumed and provides system insight for predictive maintenance. All of these features—environmental light detection, communication, and energy measurement—will further save energy and reduce operating costs. This article explores key design considerations for adding ambient light detection, communications (including wireless and power lines), and energy measurement capabilities to LED lighting systems. A reference design example is provided. An ambient light sensor (ALS) detects the amount of light in the vicinity of the sensor. These simple devices become the "eyes" of LED lighting systems and are also the key to energy savings. When the room has sufficient light source, the lighting is completely unnecessary, and the light can be dimmed or completely turned off, reducing power consumption and extending the life of the light. Key features of ALS include power consumption, lumen monitoring range, and IR and UV filtering. These sensors must be quietly in the system and do not consume excessive power, thus damaging the original intention of saving system energy. Good ALS current consumption is less than 1μA. The lumen detection range must reach the typical lumen range of the outdoor environment. 0.1lx to 100,000lx is generally sufficient for most applications. Considering system reliability, it may be necessary to adopt a slightly larger range. IR and UV filtering eliminates the spectrum of invisible light in real systems.
