  • the digital electric lighting control system was originally an extension of the calculator technology.
  • the lighting control system that uses the serial bus to transmit control information such as the network is very powerful, but the price is too high and unreasonable. Restrictions, only for some special purposes, are not universal.
  • the digital addressable lighting interface system was developed successfully in Europe and gradually accepted by the world.
  • the architecture consists essentially of a bus power supply, at least one controller, and a luminaire with a digitally addressable light interface receiver.
  • Each digital addressable light loop can control up to 64 individual luminaires, each of which is assigned an address code during initial setup. According to this address, the system can issue instructions for each luminaire separately. However, in practical applications, the luminaires should be grouped first. After storing the data in the memory of each luminaire, as shown in European Patent EP90100465.6 (USPAT5352957), the instructions can be directly issued for the group.
  • a loop can set up to 16 groups (0 ⁇ 15). Each fixture can belong to several groups at the same time. However, depending on the actual system, some products only allow one group to be set.
  • each room is at least one group, so that the controller can control the whole room as a whole, and the controller in the room must also set its control group in advance, so that the instructions can be correctly issued without cluttering.
  • Another example is an office, assuming it includes several rooms and a conference room.
  • each room must be individually controllable to automatically turn off the illumination or reduce the brightness when no one is present. If the lighting of each room is to be controlled separately, a group code must be assigned separately. The controller and sensor associated with this room must also be set with the same group code.
  • the lights in the conference room may need to be divided into at least three groups, such as the top of the podium, the conference table, and the two sidelights, to accommodate different needs such as speeches, deliberations, multimedia presentations, and briefings.
  • each room can be equipped with a dedicated group controller.
  • the group button of the group controller is pressed, the group of lamps will accept the command. Of course, these connections must be pre-set. OK, otherwise the controller and the controlled luminaire will not be able to connect.
  • the common group controller has four group selection keys.
  • each group of lights can be separately adjusted to an appropriate brightness to form an overall lighting scene.
  • Some locations such as multi-purpose conference rooms, may require several different lighting scenarios to suit different needs.
  • the lighting scene controller can be used to pre-store the data of each group, brightness and other data related to each lighting scene, and only need to press the scene selection button to retrieve the original design.
  • Fixed, common lighting scene controllers generally have 4 to 8 scene keys to choose from.
  • the addressability of digital addressable lighting interface systems is characterized by the grouping, scene setting, and dimming of the entire system.
  • the initial grouping, setting the scene, and setting the brightness can be very complicated and require professional and specialized tools.
  • a digitally addressable light interface system loop that can have 64 controllers, each with its own address (the sensor is also a controller). Each controller must be pre-set. It has been shown through practical application experience that a digitally addressable lighting interface loop, whose luminaires can only be divided into up to 16 groups, is often insufficiently used, thus creating a limitation. For example, when the number of rooms is a little more or the lighting scene is more complicated, it cannot be handled, and another loop must be added.

  • the interval instruction is valid only in the interval, and cannot cross the picture boundary repeater, so that the system instruction and the interval instruction are respectively It is the responsibility of the division to eliminate the complicated setting work, and each interval controller naturally performs its work within the interval defined by the boundary repeater.

In order to meet the needs and practicability of the actual operation of the lighting control, the technical solution is directly controlled by the room or the area.
  • the digital information transmission bus is divided into separate partitions by a picture boundary repeater device. System commands can be forwarded across the repeater; regional commands cannot be truncated across the repeater and can only be valid within the interval defined by the arterial repeater.

Since interval instructions cannot cross the picture boundary repeater, they naturally do not interfere with facilities outside their range.
