DALI (Digital Addressable Lighting Interface)
Diagram
Digitally addressable lighting is now emerging as a
popular means for controlling complete lighting
environments for a wide variety of different applications. Individual control of each lamp enables the end user to
precisely deliver the correct amount of light when and
where it is required. Managing the light in this manner
allows for a massive reduction in global energy
consumption due to lighting. Industrial environments can
conserve the total energy required for lighting while
actually increasing light quality in certain areas at given
times.
Applications for this system include building management or studio lighting where it is desired to control single or groups of lamps for conserving energy, performing lamp maintenance or creating precision lighting effects. between the system designer, user, fire authority, building control officer and system installer.
DSI Dimming Diagram
This system is commonly employed in larger installations, with scene-set controllers or energy management systems. Digital dimming is also used for Infra-Red remote control, PIR presence detection and automatic daylight sensing.
switchDIM Dimming Diagram
SwitchDIM operates for ON / OFF and dimming is by means of a push-to-make (retractive) switch, and is the simplest form of dimming. A brief operation of the switch (<0.6sec), will switch ON or OFF. When the push to make switch is held, the ballasts are dimmed. On a further push, the ballasts is dimmed in the opposite direction.
1-10volt Dimming Diagram
Also known as High Frequency Regulating – Analogue dimming employs the use of a 1-10V DC control voltage. A dimming range of 100% down to 3% or 1% depending on wattage/type of lamp used is available.
The method of control for this system is typically by means of either a rotary or slider potentiometer. Analogue (HFR) dimming ballasts can also be used with many available scene-set controllers.
