The benefits of DALI dimming system


DALI stands for Digital Addressable Lighting Interface. Because it is designed for architectural and commercial lighting, it sets high standards for global digital lighting control. In addition, DALI is interchangeable with different brands of equipment. With a single interface, you can electronically control all light sources throughout a commercial building.


The DALI lighting control system is easy to install, which means your business can reduce downtime. Moreover, the fact that installation costs less by requiring less labor time and workers' wages to complete the installation and requiring simple wiring.


The DALI system has multiple uses because it can be customized to your specific needs. There are no settings for all situations and buildings. Similarly, software configuration or reconfiguration is possible without rewiring or hard-wiring. It is also compatible with building management systems.


As an all-digital system, DALI can provide distributed intelligence without external switch relays. Up to 16 lighting solutions can be stored on a single DALI operating device. With the automatic function, you can choose other options, such as sensor-controlled switching and dimming.


Advantages of DALI:

Users have the following options when installing DALI ballasts in their lighting system:

• Simple wiring of control lines (no group formation, no polarity)

• Control of individual units (individual addressing) or groups (group addressing) is possible

• A simultaneous control of all units is possible at any time

(built-in initial operation function) through broadcast addressing)

• No interference of data communication is to be expected

due to the simple data structure

• Control device status messages (lamp fault, ....),(report options: all / by group / by unit)

• Automatic search of control devices

• Simple formation of groups through “flashing“ lamps

• Automatic and simultaneous dimming of all units when

selecting a scene

• Logarithmic dimming behaviour – matching the eye’s sensitivity

• System with assigned intelligence (every unit contains

amongst other things the following data: individual address, group assignment, lighting scene values, fading

time, ....)

• Operational tolerances of lamps can be stored as default

values (for example for the purpose of energy savings

maximum values can be set)

• Fading: adjustment of dimming speed

• Identification of unit type

• Options for emergency lighting can be chosen (selection

of specific ballasts, dimming level)

• No need to switch on/off the external relay for the mains

voltage (this is done by internal electronic components)

• Lower system cost and more functions compared to

1–10V-systems
