DALI intelligent lighting system

Ankerui DALI Bus Intelligent Lighting System

AcrelDALI intelligent lighting systemBased on the international standard of "Digital Addressable Lighting Interface" (DALI), precise control of lighting equipment is achieved through digital communication. This system has independent addressing function for individual lamps, supports dimming control for single lamps or lamp groups, and can flexibly design lighting schemes without changing the circuit. It is suitable for large public construction projects such as hospitals, schools, hotels, sports venues, airports, etc1The system is mainly composed of DALI controller, panel, sensor, touch screen and upper computer software, providing multiple control mode options1.

System technical parameters and hardware configuration

Bus cable specifications

• DALI system bus: Recommended ZR-BVV 2 * 1.5mm ² cable, bus voltage 16V, maximum voltage drop 2V, maximum communication distance 300m, supports co management with power supply lines.

• 
  

• ALIBUS system bus: using Cat5e and above UTP pure copper network cables with a diameter of 0.5 ± 0.01mm, in compliance with IEC61156 standard.

System wiring diagram

Our company's intelligent lightingThe application scenario of DALI dimming controller is a single master application scenario, which means that there can only be one DALI dimming controller on the control device on the DALI bus.

A standardThe DALI bus can carry up to 64 independent address power supplies (i.e. 64 lamps),Each lighting fixtureneedconsumehighest 2 mA current，The maximum current applied by all power sources shall not exceed 250 mA。

Our company's intelligent lightingThe rated current of the DALI dimming controller is 150mA, which is sufficient to carry 64 DALI lamps.

The DALI bus does not differentiate between positive and negative, simply connect it to the DALI interface of the lighting fixtureAt the same time, it can be co managed with the power supply line.

Note: If oneDALI system has more than 64 points or system current greater than 250mAThe signal may attenuate, distort, and cause system errors, and some components may not be able to communicate, resulting in unstable system operation.

System wiring diagram

Modify the drawings based on the on-site situation and determine the construction plandrawingIn the future, we need to followThe control of the DALI system involves connecting each controlled circuit load to the distribution box. It is required to confirm the number of wires in each pipeline based on the number of circuits, identify the distribution box where the control circuit is located, and connect the pipelinespre-Buried well.

DALI controllers, panels, sensors, these controlsThe modules are connected in a hand in hand manner, and if there are branches, an extended Ethernet interface is used to coordinate their use.

Installation of DALI driver:

The DALI driver is installed in a high-voltage distribution box. During the production process of the distribution box, sufficient guide rail space should be reserved, and all control circuit loads should be connected to the DALI driver,DALI driverThe rated voltage isAC220V±10%，Please ensure power supplyvoltagemeet the requirements.

Panel installation and wiring

On site panel to ground distanceAt a height of 1.3 meters, it is installed using a standard 86 bottom box, and the opening size must be appropriate. There are two mesh ports at the back of the panel, which are convenient to connect in a hand held manner.The installation arrow indicates an upward direction for correct installation, as shown in the following figure

Typical application scenarios

AcrelDALI intelligent lighting systemWith flexible control methods and high reliability, it is widely used in:

• Hospital: Regional dimming meets the needs of diagnosis, treatment, and rest scenes.

• Large venues: achieve crowd sensing and lighting control through sensors.

• Transportation hub: zoning lighting management for tunnels, stations, and other places.

The system effectively reduces construction complexity and enhances the intelligence and energy efficiency of lighting systems through standardized interfaces and modular design, providing efficient lighting solutions for large-scale public construction projects.
