DALI DIMMING CONTROL

Overview

Our ELC system's DALI System has several distinctive features. It was developed to connect to our ELC system based on the standard DALI protocol, and sensor modules can be connected to the DALI communication line to enable sensor-based control. Up to 64 DALI Dimming Modules can be connected to a single DALI Master (also called a DALI Controller by other manufacturers). To eliminate the inconvenience of configuration caused by random addresses when replacing luminaires, each DALI Dimming Module is equipped with a hardware address port, eliminating the need for cumbersome line checks during reinstallation. One of the most important considerations for a DALI system capable of individual luminaire dimming control is communication traffic when a large number of modules are installed. We have addressed this issue through our ELC system software. In addition, we provide a solution for glare and flickering that may occur during LED dimming by adjusting the frequency through software. We encourage you to take full advantage of our competitive DALI system and reliable ELC system.

IEC 62386 standard protocol
DALI: Digital Addressable Lighting Interface
Dedicated digital lighting control protocol
Digital transmission method that can replace 0-10V analog control, enabling lighting dimming control (254-step digital dimming output range)
Individual digital control is possible by assigning separate addresses to DALI Devices. These DALI Devices can also be programmed to operate in Groups and Scenes.
The lighting system can be reconfigured through programming changes without modifying existing wiring.
Bidirectional communication between DALI Devices enables responses regarding device errors and status information.
Wiring is simple with two lines, eliminating induction issues with high-voltage power lines.
DALI power and data are transmitted over two lines without a separate bus cable, and the wire polarity can be reversed.

Key Software Functions

DALI Master

Up to 64 DALI Devices can be connected to a single DALI Master
Up to 999 DALI Masters can be connected to the ELC system
DALI Device types include LDM, DALI-OCC, DALI-PH, etc.
Global interlinked control between DALI Masters: A single global Smart Touch Switch can simultaneously perform Group and Scene control of LDMs connected to multiple DALI Masters.

LDM: LED DALI Dimming Module

DALI Dimming Module for LED lighting based on the IEC 62386 standard protocol
Up to 64 units can be connected to a DALI Master
16 Group and Scene settings
Communication line polarity does not need to be distinguished; communication uses two standard wires
Three output types: PWM signal, 0–10 V signal, and direct LED load output
Three output capacity ranges: 10–20 W, 21–60 W, and 61–180 W

DALI Device Installation Example

The SMPS and LDM are separated, allowing only the faulty part to be replaced during future maintenance
If an LDM fails, it can be easily replaced by changing its Address using the Program Port

Comparison of Constant Voltage and Constant Current LED Drivers and the Suitable Method for Dimming Control

Method	Constant Voltage (CV)	Constant Current (CC)	Constant Current/Constant Voltage (CCCV)
Characteristics	Maintains a constant voltage regardless of load changes Compares the output voltage with a constant-voltage diode and adjusts the voltage drop between the power source and load	Maintains a constant current regardless of load changes and compares the output current to keep it constant	Dual CC + CV control method
Dimming	Available (When PWM dimming, a current-limiting method, is applied to a constant-voltage system, the voltage remains constant while the current can be varied freely, making brightness adjustment easy)	Not available (When PWM dimming is applied using a current-limiting method, the characteristic of maintaining the specified current can distort the waveform, resulting in irregular output and making accurate dimming control difficult)	Available (PWM dimming is easily applied through the dual-control constant-voltage compensation circuit)
Dimming Control Waveform	Current limiting is smooth during PWM dimming control, making dimming control easy	The characteristic of maintaining constant current during PWM dimming makes dimming control difficult	Current limiting is smooth during PWM dimming control, making dimming control easy
Conclusion	For dimming control methods applied to LED luminaires (DALI Dimming Module, Wireless Dimming Module, and 0-10V DC Dimming Module), the SMPS (LED Driver) inside the LED luminaire must use either a constant-voltage method or a constant-current/constant-voltage method.
