China Emergency Light – External Emergency Lighting: Design Principles, Lux Level


       China Emergency Light     indicates – If the power of your building is cut off, you should have emergency lighting to fully illuminate the environment to ensure everyone’s safety. Employees, visitors and anyone else should be able to leave without any hidden dangers. If you have an emergency lighting system that is properly set up, the appropriate signage should be attached to all available outlets.

  These measures are very important to help people leave the house safely. However, there are still some factors that can complicate matters, for example, if the outside is night and dark.

  There are a number of issues you need to consider:

  Can people navigate safely in the dark?

  What if a visitor does not know the location?

  What if there is something left where it should not be and this can lead to danger?

  Obviously external lighting is a priority, but if all power is turned off in an emergency, it will be useless and can make the environment very dangerous and can be painful.

  The answer is external emergency lighting. Lighting can be programmed to be carried out during other emergency lighting so that all areas are always safe.

  Why it is very important to have high quality external emergency lighting

  Inferior systems are not the best choice for external emergency lighting because they must be able to withstand many factors such as weather, dust and bugs.

  External emergency LED lighting manages to address all standards while providing the most efficient form of alternate lighting.

  Emergency lighting design

  For effective emergency lighting, follow these design guidelines:

  Escape Route Signs – Make sure they are illuminated and they are illuminated when needed.

  Stairs – Make sure each tread receives light.

  Intersections and intersections – Ensure that horizontal and directional changes are adequately illuminated.

  Close to emergency and fire call points.

  Final exit – Make sure to provide illumination outside the last door.

  Also, keep in mind that there are two types of emergency lighting – maintenance and non-maintenance.

  The maintained luminaires are permanently illuminated and remain lit even when the power is turned off.

  Lamps that are either continuously or unmaintained can be turned on and off normally. It is worth noting that if the power supply fails, they will automatically turn on.

  Emergency lighting lux level

  Escape route (up to 2 meters) – not less than 1 lux along the centerline, the center zone consists of not less than half of the full width to 50% of this value. A roughly wider escape route is considered a multiple 2 meter strip or is considered an open area.

  Open area (anti-panic) – Areas equal to or greater than 60 square meters require a ground illumination of no less than 0.5 lux, excluding the boundary of 0.5 meters from its perimeter. The ratio of maximum illumination to minimum illumination should not be greater than 40:1.

  High-risk areas – Areas considered high risk should not be less than 10% of the illumination required for the task performed. It should not be lower than 15 lux.
