Architectural Lighting Measurement

Quantify luminance, glare, and visual comfort with image-resolved photometry

Architectural lighting design requires more than illuminance values. To evaluate real visual conditions in indoor and outdoor spaces, you need spatially resolved luminance data, reliable glare metrics, and traceable measurement results. TechnoTeam’s LMK imaging photometers provide calibrated camera-based luminance measurement for architectural applications — from office environments to daylight-dominated atriums and urban facades.

Why Luminance Imaging Matters in Architecture

Point-based instruments (spot photometers) only measure single values. In contrast, LMK systems capture the full luminance distribution L(x,y) of a scene, including geometric context such as position and object size. This allows the objective evaluation of lighting environments as they are perceived by the human eye.

Indoor Architecture – Discomfort Glare and Visual Comfort

In interior architecture, glare and contrast strongly influence user comfort and performance. LMK systems enable metrological glare assessment directly from real measurement scenes.

Emergency Lighting – Safety-Relevant Luminance & Contrast Evaluation

Emergency lighting must ensure clear visibility of escape routes, obstacles, and safety signage under critical conditions. Instead of relying on isolated point readings, LMK imaging photometers document scene-based luminance and contrast performance across the full visual field. This supports objective safety documentation and helps identify local weak points that may be missed by spot measurements.
