Δεν έχω δει controller για DALI... να φτιάξεις γίνεται, αλλά θα πρέπει να κάνεις λίγο διάβασμα με το DALI για να ξέρεις τι εντολές να στέλνεις. Με ενα arduino controller μπορεί να είναι αρκετά εύκολο...

Συμφωνα με το παρακατω κειμενο πρεπει να υπαρχουν ελεγκτες για οτι μπορει να φανταστει κανεις... λεει οτι οι ελεγκτες μπορουν να προγραμματιστουν με lighting scene values, fading time .....


DALI is an acronym and stands for “Digital Addressable Lighting Interface“. It is an international standard that guarantees the exchangeability of dimmable ballasts from different manufacturers. The DALI-interface has been described in the fluorescent lamp ballast standard IEC 60929 under Annex E.

Features available when installing DALI ballasts are:

• • • Simple wiring of control lines (no group formation, no polarity).
    • Control of individual ballasts or groups is possible.
    • A simultaneous control of all ballasts is possible at any time.
    • Ballasts status messages (lamp fault ....).
    • Automatic search of ballasts.
    • Automatic and simultaneous dimming of all ballasts when selecting a scene.
    • Logarithmic dimming behavior – 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
    • 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)

DALI has been defined for:

• • • a maximum of 64 single ballasts (individual addresses)
    • a maximum of 16 groups (group addresses)
    • a maximum of 16 scenes (scene light values)

Each ballast stores its own set of parameters:

• • • Individual addresses
    • Group assignments
    • Light scene values
    • Fading times
    • Emergency lighting level (System Failure Level)
    • Power On Level
