RENOVATION, INSTALLATION, CONFIGURATION AND HANDOVER THE PROJECT
I WAS RESPONSIBLE FOR IMPLEMENTING A MODERN ARTIFICIAL LIGHTING SYSTEM AS PART OF A SPECIALIZED PROJECT THAT RAN FROM JANUARY 2021 TO JULY 2021..
My primary role involved designing the electrical wiring layout and overseeing its installation with my technical team. We developed a lighting control system based on the DALI protocol, using components from ABB and integrating it with modern lighting fixtures from Tridonic. The system provided seamless 0–100% dimming capability, allowing users to precisely control brightness levels to meet both functional and aesthetic needs.

SMART RESIDENTIAL LIGHTING DESIGN WITH SEAMLESS DIMMING AND CUSTOMIZED SCENARIOS

New lighting design
The building, a residential property constructed several years ago, was undergoing renovation when the client requested an entirely new lighting design to align with updated architectural requirements. The key objective was to implement a smart lighting system that would enable users to gradually adjust brightness levels from 0% to 100% and activate customized lighting scenarios at the simple touch of a button. This requirement demanded both aesthetic sensitivity and technical precision in the system’s design and integration.
TAILORED LIGHTING SOLUTIONS WITH PRECISION, COMPATIBILITY, AND PERFORMANCE

Based on the architectural requirements, the lighting components used in this project varied in shape and housing to meet different design needs. The LEDs within these fixtures were controlled via DALI LED drivers, which provided smooth dimming through constant current technology. As part of the project, we were responsible not only for designing and specifying the control components, but also for creating a detailed bill of materials for the custom lighting fixtures, ensuring full compatibility and optimal performance throughout the system.
SEAMLESS INTEGRATION OF DALI AND KNX FOR SMART, RELIABLE LIGHTING CONTROL

In the DALI system, the controller manages the DALI LED drivers to regulate lighting. In our project, the DALI system was integrated with the upper layer of the Building Management System (BMS), which is based on the KNX protocol. This integration required collecting and coordinating components from various manufacturers to ensure seamless operation and deliver the desired lighting control outcomes.

FROM CAD DESIGN TO REAL-WORLD INSTALLATION: POWERING LIGHT WITH PRECISION
Electrical Wiring Job
Electrical Wiring Job
My task was to design the electrical wiring in CAD and then implement the wiring with my electrical installation team in reality. It started by fixing the specific pipes and then filling them with wire from the electrical cabinet to the consumers like lights.

CHALLENGES I FACED
First Challenge
First Challenge
One of the main challenges I faced in this project was the precise installation of lighting components on the ceiling. According to the lighting manufacturer’s design drawings, each fixture had to be installed at specific dimensions and locations. However, since this was a renovation project, the actual ceiling structure differed from the original plans. To overcome this challenge, we collaborated closely with the customer’s team to adjust the ceiling layout. By using specialized tools such as laser meters and dedicating many hours to accurate measurement and alignment, we were ultimately able to install the lighting fixtures in the correct positions.
Second Challenge

The other challenge I faced was integrating the new DALI controller by ABB into the project. To address this, I studied the manual, conducted several tests, and was ultimately able to configure the system successfully.
SUMMARY
This project provided me with valuable hands-on experience in integrating DALI lighting systems with KNX-based building management systems, as well as deep insights into the practical requirements of lighting installation. It was a unique learning opportunity that enhanced both my technical and project coordination skills. The knowledge I gained has proven to be highly beneficial, and I continue to apply these lessons in my subsequent projects.
