A complete set of technical lighting illustrations for a professional consultancy — from client sketches to ~40 refined final drawings across three spatial typologies.

Overview
What was the challenge?
A lighting consultancy commissioned me to create a set of technical illustrations to communicate lighting scenarios to their clients — covering 3D room setups, outdoor environments, and 2D room plans. The drawings had to be clear, precise, and visually cohesive across all product families.
How did we approach it?
Rather than designing each illustration from scratch, I started by establishing a validated visual language per drawing type. I agreed one style with the client for each category — 3D interiors, outdoor scenes, and 2D plans — and then scaled it to the full set of around 40 drawings.
What came out of it?
A complete library of technical lighting drawings, all sharing a consistent visual identity agreed with the client and refined through direct feedback. Each drawing communicates luminaire behaviour clearly, helping the consultancy present lighting decisions before installation.
Design Process
The client provided hand-drawn sketches and reference images to communicate the lighting scenarios they needed illustrated. Each sketch conveyed a spatial context, a set of light sources, and a mood — from quiet residential interiors to outdoor urban scenes and clean 2D technical floor plans. These references became the brief: understanding them in depth shaped every decision that followed.
I explored multiple visual styles for each of the three drawing types: 3D room interiors, outdoor scenes, and 2D floor plans. I developed different approaches to line weight, shading, abstraction level, and luminaire representation, and presented them to the client. For each category, one style was selected and refined through direct feedback rounds. That approved style then served as the template for the full set of around 40 drawings — ensuring consistency while allowing each illustration to communicate its specific lighting scenario clearly.
With the visual language locked in per category, I produced the full set of drawings — each one incorporating the client's corrections and adjustments from the approval round. Precision and consistency across the set were the priorities: every illustration needed to communicate the lighting behaviour accurately enough to support real design decisions, while maintaining the visual coherence of the library as a whole.
