ljusdesignen

Ljusdesignen is the praxis of shaping light for built environments and events to achieve aesthetic, functional, and sustainability goals. It covers architectural and interior lighting, outdoor urban lighting, stage and film illumination, and product lighting. The practice aims to influence how spaces are perceived and used by controlling luminance, color, contrast, and shadows while addressing energy use and occupant comfort.

Historically, electric lighting enabled intentional design of atmosphere and function. In the 20th century, modernist approaches integrated lighting with architecture, and with the rise of LEDs and digital controls in recent decades, lighting design expanded to tunable, networked, energy-efficient systems that emphasize human well-being.

Core concepts include illuminance and luminance planning, color temperature and rendering, glare control, and appropriate contrast. Ljusdesignen also emphasizes daylight integration, energy efficiency, and user needs through human-centric lighting. Dynamic and scene-based schemes are common in offices, healthcare, education, and cultural venues.

Practices rely on photometric data and simulations using software such as DIALux, Relux, or Radiance, and on coordination with architects, engineers, and clients. Luminaires, control systems (DALI, DMX), and BIM workflows are typical tools. Designers consider standards such as EN 12464-1, EN 1838, IES guidelines, and national codes, validating performance through commissioning.

Professionally, lighting designers work in architectural firms, consultancy practices, or media studios. Education often includes dedicated programs in lighting design or related fields, with associations such as the International Association of Lighting Designers (IALD) and the Society of Light and Lighting (SLL) providing resources and accreditation.
