Is there any way to solve the communication traffic problem? Please review.

… When more than 1,000 DALI Dimming Module are installed, communication traffic is expected to malfunction due to poor communication in a busy state.
…Solution :
 1) For each DALI Master (or DALI Controller), 64 DALI Dimming Module can be connected, but it is recommended to install up to 50 DALI Dimming Modules for smooth communication.

 2) It is recommended to install as many main communication devices as possible in the lighting control system and connect and operate them with one communication device per 1,000 DALI Dimming Modules.

 3) There is a function to adjust the communication interval of the STATUS (illumination state, presence detection state, dimming current state) of the DALI Dimming Module in the software program, and it solves the traffic at the communication speed.

 Is there a way to solve the problem when applied as an integrated ballast? What are the alternatives?

 1)There is a condenser in the ballast of the LED luminaire (SMPS), and the LED lighting is controlled by this condenser. The life span of the capacitor of a domestic high-quality ballast is about 5 years, and the ballast should be replaced after 5 years. DALI dimming module and ballast are integrated. The ballast must be replaced every 5 years, and the dimming program needs to be reset again.

 2)An alternative to this problem is to apply the ballast and dimming module separately. As the nation’s largest achievement, the stabilizer and the dimming module are installed and used separately in the government offices of Sejong City, KEPCO Naju, and Lotte World.

 Is there a way to solve the problem when applying the DALI Dimming Module to LED lighting fixtures? Please review.

 1)The SMPS (Power Supply) type of LED should be CCCV (Constant Current Constant Voltage) type, but it can control the quality of dimming when connected to DALI Dimming Module : No glare and flickering. Due to price issues, domestic LED lighting companies are using a ballast as a constant current (CC) method, and in this case, a problem arises in controlling high-quality dimming.

 2)When flickering or glare occurs in the software program, the frequency is adjusted and downloaded to each DALI Dimming Module to enable proper PWM frequency generation.
