Lighting Control

Since the 1990s, the lighting industry and the technology of light control have made great progress. With the development of microelectronics and communication technology, a complete light/licht control system is integrated, which is able to control light scenes with the whole light effect. Therefore, the development of lighting control has been urgent for the industry. At present, the dominant control technology of lighting control applications is digital addressable lighting interface (DALI), which is widely used in modern lighting control applications.

DALI is a digital control protocol developed according to IEC 60929. In this protocol, lighting products are required to have a two-way communication ability, which can control the on/off state of not only LED lighting sources but also traditional lighting sources such as fluorescent and HID and electric ballasts. Therefore, it is an ideal light control technology for modern lighting control applications.

The application of DLC7 technology should be analyzed. DLC7 is a lighting control protocol developed by the company Virtual Dali, which is based on and is compatible with IEC 60929. DLC7 is mainly for relatively complex applications such as stage lighting, stage effect lighting and background music. It combines the functions of switching lighting scenes and controlling dimming in one system, and also has the function of networking multiple DALI control equipment, which can meet large-scale lighting control applications.

The working principles of DLC7 lighting controller are relatively simply: when any DLC7 compatible light is connected to the DLC7 lighting controller, the DLC7 bus will send a broadcast signal to the connected devices, prompting them to reply with their identity codes, which are stored in the lighting controller\'s memory. Therefore, when we want to adjust any function of the light, the lighting controller only needs to send out some specific instructions on the DLC7 bus, and the connected equipment will realize it. In this way, the goal of controlling multiple connected equipment with only one controller is realized.

With the development of technology, DLC7 lighting control technology is becoming more and more advanced. Its best feature is its ability to control the light scene and dimming of multiple connected equipment at the same time, and link them together to form a complete lighting control system. It is widely used in scenarios such as stage lighting and stage effects lighting, and is also used in many large-scale lighting applications.
