As an emerging light source, LED has received extensive attention. At present, the research focus of the industry is on the improvement of its optical and thermal properties. This paper attempts to explore the superiority of LEDs for indoor lighting from the perspective of visual ergonomics and intelligent lighting.
As a light source that has developed rapidly in recent years, LED has significant advantages over traditional light sources, such as long life, high light efficiency, fast response, artistry, safety, flexibility and reliability. However, the main application of LED is still in the field of backlights and outdoor lighting such as street lamps and landscape lights. In the field of indoor lighting, there are still some shortcomings, such as high cost, poor color rendering, high brightness and consistency. In terms of the advantages and disadvantages of LED integration, from the application point of view, in indoor lighting, we should make full use of the advantages of LED and avoid its shortcomings. In the future, LED will be widely used in indoor lighting, and its technology combined with lighting control can achieve better results.
The key to combining LED with lighting control
Lighting control is a distributed lighting measurement and control system composed of computer, wireless communication data transmission or power carrier communication technology and electrical control technology to achieve the adjustment of brightness and timing of lighting, timing control, regionalization and personalization of lighting scenes. Control [1]. Generally, the bus control mode is adopted, which requires that the controlled luminaire can be digitally dimmed and has a good fast response characteristic.
At present, the lighting control is generally in the form of a bus, digitally dimming a halogen lamp, a fluorescent lamp with a digital dimming rectifier, etc., realizing dimming of the combination of lamps in the area, adjusting the ambient illuminance, or adjusting the color temperature by fluorescent lamps of different color temperatures, and lighting performance. The technique is still relatively simple. The advent of RGB mixed-light LED technology makes it possible to adjust the ambient light color and is very convenient. LED adjustment generally adopts PWM duty cycle adjustment mode, which can be conveniently implemented in digital form. As long as the digital interface is reserved on the drive, communication with other digital systems is easy, making system construction very simple. As shown in Figure 1.
The key to combining LED with lighting control is to use the flexibility and artistry to choose the right system topology. The LED lighting system generally has a large number of nodes, a large number of communication channels, a large system scale, and a high requirement for system response speed.
At present, many lighting control systems use RS485 bus control, which is a control mode based on master-slave structure. The controller sends control commands or queries sensor detection values ​​through master-slave response mode and timing inspection. RS485 only specifies the physical layer, which is convenient for customizing communication with the system. The practice in the field of lighting control is that each LED luminaire has a built-in MCU control and is connected to the bus via an RS485 interface chip. This method is simple and reliable, but the application layer standards are not uniform, and the engineering application configuration is inconvenient.
