Emergency Lighting Design Techniques

Explore emergency lighting design by understanding automatic illumination when power fails, and distinguish emergency escape and standby lighting within the theory framework.

Emergency lighting design provides automatic, sufficient illumination during power loss to enable safe evacuation of occupants, reducing panic and danger in both internal and external spaces.

Learn about standby lighting and the three emergency escape lighting types—escape route, open area (anti panic), and high risk task area lighting—plus their roles and lux levels.

Integrate emergency lighting design objectives into the building by choosing between self-contained units and central battery systems, considering building size, luminaire classification, test options including test modules, and duration requirements.

Plan emergency lighting schematics for escape routes on floor plans and office blocks, detailing central and essential luminaires, fire alarms, exit signs, one-lux corridors, and AutoCAD legends.

Identify mandatory points of emphasis for luminaire placement, including final exits, exit signs, stairways, and alarm areas, and design emergency lighting layouts using AutoCAD and Deluxe Evo.

Determine the maximum viewing distance for exit signs by following format and green on white, with 200x height (internally lit), 100x, or up to 2200x for self-illuminated signs.

Identify and illuminate essential areas for emergency lighting, including escalators, toilets, lifts, control rooms, hazardous and open areas, indoor car parks, and stairs, to reduce panic and ensure safety.

In step four, add luminaires to achieve one lux along the center line of an escape route. Maintain a four-to-one uniformity, noting UK deviation allows 0.2 lux on unobstructed routes.

Learn emergency lighting design for anti-panic core areas over 60 m², applying 0.5 lux minimum with a 0.5 m perimeter offset, and placing luminaires at exits, toilets, lifts, and corridors.

Develop emergency lighting design skills by applying electricity basics, reading drawings, understanding LG 19/SL standards, and selecting luminaire types, while reading calculation results with deluxe Evo and AutoCAD.

This lecture contrasts self-powered and centrally powered emergency lighting systems. It explains that self-powered luminaires carry their own battery, while central systems use a central power source with automatic changeover.

Identify the two emergency lighting power sources—batteries (including UPS) and generators—and distinguish self-contained, central battery systems, and generator placements to ensure reliable performance during power failures.

Clarify maintained vs non-maintained emergency lighting, including mains powered operation with backups, activation during power outages, and the role of combined or switchable luminaires with emergency and normal lighting.

Explore emergency luminaires, from decorative to bulkhead and surface-mounted fittings, and learn to access photometric files, differentiating three hour non-maintained and central battery systems for reliable emergency lighting.

Learn to read emergency lighting datasheets to identify key specs: IP rating, emergency duration, battery type, mounting options, and photometric data for compliant luminaires.

Learn to obtain photometric files for emergency lighting: loom search with filters, brand plugins for offline access, or download catalogs via Deluxe Evo brands tab or brand websites.

Explore specifying emergency luminaires, covering mains voltage, central battery vs self-contained options, IP ratings, lamp type, wattage, duration, and essential datasheet details.

Master Dialux evo basics with hands-on tutorial, from preparing rooms and selecting luminaires to running emergency lighting calculations and exporting layouts to AutoCAD, with a bonus on relaxed and AGI32.

Learn how to prepare rooms for emergency lighting calculations using Deluxe Evo software, import plans, set units, draw rooms, label spaces, and align luminaire placement with 60 by 60 grids.

Learn to design emergency lighting layouts by selecting luminaires, achieving target lux values, and using auto arrangement to visualize and verify corridors, kitchens, toilets, and stairs.

Explore how to design emergency lighting for a corridor using central battery systems, selecting emergency luminaires, creating escape routes, and evaluating uniformity through active light scene calculations.

Clarify whether emergency lighting is required for spaces under 60m². Explain that standby or anti-panic lighting provides at least 1 lux in working areas.

Learn to set up an emergency calculation in Relux by duplicating the project, converting selected luminaires to emergency, calculating lux per room, and saving results.

Extract the emergency lighting calculation report in Relux for client submittals by selecting essential pages, including the first page and table of contents, using A4 layout and emergency file naming.

Identify mandatory emphasis points for emergency luminaires—final exits, exit signs, intersections, stairs, toilets, and lifts—and apply correct signage formats and minimum illuminance per BS 5266 part seven of 1999.
