Once requirements are clearly defined, the project moves into the technical design phase. Designers employ professional lighting simulation tools such as DIALux to perform precise illuminance calculations and generate pseudo‑color renderings that visualize light distribution across each space. These simulations help identify potential issues like excessive glare, dark zones, or non‑uniform illumination before any installation begins – ensuring that the final light environment is both comfortable and functionally effective.
Lighting System Design – This core activity involves selecting appropriate luminaires based on type, wattage, color temperature (e.g., 2700K for warm ambience, 4000K for task lighting), and luminous flux. Simultaneously, the control system is architected, specifying controllers, sensors (occupancy, daylight harvesting), gateways, and user panels. For example, in a recent office retrofit, the design team chose tunable‑white downlights with a 90+ CRI to support circadian‑friendly lighting, paired with a central DALI gateway and wall‑mounted touch panels for manual override.
Wiring and Network Planning – This step defines how power and control signals are distributed. The designer must decide between wired protocols (DALI, KNX) offering robust reliability for large commercial spaces, or wireless solutions (Zigbee, Wi‑Fi) for cost‑effective residential retrofits. Best practice recommends separating high‑voltage AC lines from low‑voltage control cables to minimize electromagnetic interference, and reserving dimming circuits in key zones such as living areas or boardrooms. A mixed approach is often used: a KNX backbone for critical paths with Zigbee endpoints for flexible additional sensors.
Delivery of Construction Drawings – The final output includes detailed floor plans showing fixture locations, control logic diagrams, and comprehensive wiring schematics. These documents must be reviewed and formally signed off by the client before procurement and installation. In one high‑end residential project, such drawings prevented a costly conflict between lighting tracks and HVAC ducts, saving two weeks of rework. This rigorous documentation ensures that every stakeholder – from electricians to programmers – works from a single, verified blueprint, guaranteeing that the final system matches the client's vision while complying with local electrical codes.
Base on the short essay above, please help me draw a simple picture. Just draw it in simple line diagram, no many words for description in the diagram.
