Emergency Lighting Design Guide The application of emergency lighting

This design guide will help you to plan and implement an emergency lighting installation that satisfies all the legal requirements and ensures safe evacuation in the event an emergency.

What is emergency lighting? Emergency lighting operates automatically when a lighting circuit loses the mains power supply. Emergency lighting falls into two categories:

Performance, Efficiency, Comfort (PEC) All Thorn products are designed to adhere to three core values: performance, efficiency and comfort. This is the PEC programme, which delivers quality in a lighting installation.

These stringent requirements mean that tungsten halogen solutions are often used in these applications. However, Thorn has developed special emergency “œ`ՏiÃÊ̅>ÌÊi˜>LiÊvˆÌ̈˜}à with fluorescent lamps to meet these regulations.

The lamp is lit again in less than ä°ÓxÊÃiVœ˜`Ã]ÊVœ“«>Ài`Ê܈̅ a typical 2 second restrike for a standard emergency luminaire. This solution is particularly useful in applications such as cleanrooms and kitchens, which require fewer surfaces where dust or particles may gather and higher emergency light levels to manage the safe shutdown of equipment.
