The advent of the Internet of Things era has brought earth-shaking changes to the lighting industry. Everything will have huge data, no matter what equipment is equipped with its own network devices, such as lighting systems can automatically adapt to the environment to bring appropriate lighting. Of course, lighting the Internet of Things is inseparable from sensors, and it is expected that sensors will become the demand for intelligent lighting systems.
Everything today is becoming "smart", especially in the Internet of Things (IoT)-related markets that are considered to have tremendous growth potential. The new possibilities of the Internet of Everything and the huge data from it provide a vision for the development of countless products. For example, at breakfast, the kitchen equipment prepares fresh coffee and hot bread; the washing machine automatically stops the laundry before red dyeing all the white clothes in pink; in addition, at home, in the shopping center or on the street, the lighting system They are automatically adapted to the environment to provide the right lighting.
1 monitoring, networking and controlWith the introduction of light-emitting diodes (LEDs), the development concept and design process of lighting equipment have undergone tremendous changes. In order to be able to use more effective control systems, we must learn new electronics and add new features to product design. There are still many places to explore in terms of how to use lighting more intelligently.
The luminaire is the ideal sensor node. Each room has lights, and these lights are usually located in the center of the room. Higher intelligence can be easily achieved by adding sensors such as light quality, temperature, humidity, air quality or space occupancy monitoring. These data can be collected and transmitted to other connected devices in the room. However, the system will react only when the correct data is collected.
How to build a bridge between the physical world and the digital space? What are the specific requirements for applying sensors to luminaires? The right combination is very important.
2 data collection and "smart" useMost buildings currently have some basic elements, including walls, doors, windows, furniture or gathering areas, air conditioning or ventilation systems, and lighting, etc., since the electrical network is distributed throughout the building and each room is installed. With fixtures, the luminaire is clearly a great choice for sensor "hot spots" because it contains all the necessary elements: electricity, the central location of the room, and people.
What people want to monitor, this is what manufacturers need to think about, and it also helps them use proprietary knowledge to develop targeted sales strategies that cannot be replicated quickly.
Adding air quality and humidity monitoring capabilities can make building automation smarter, save energy and increase system efficiency. In addition, active lighting control ensures that employees feel comfortable and energized throughout the working day, so they remain committed. The concept of smart sensors and controls is becoming increasingly important given the requirements of ENERGY STAR and other international standards.

Of course, the adoption of sensor technology is bound to increase the material cost (BOM) of the luminaire. But we also need to think about: “What added value does sensor technology create?†“Which features will help open up new markets?†Detection of volatile organic compounds (VOCs) in the air, early warning systems for fire monitoring, or The complete spectrum of human-centric lighting (HCL, Human-centric lighTIng)? Handheld device users often seldom complain about the hardware part, but are often disappointed that the device does not have a specific sensor, causing its app to have no new features.
