Light Levels During an Emergency

Open Areas
The safest, quickest escape route without obstruction should be lit to a minimum of 1 lux during an emergency. Should the open area be less than 60m² and not part of an escape route then emergency lighting is not required. However, the exit doors for the emergency escape route must have signs or an emergency bulkhead.

Designated Corridors
An escape route should not be obstructed and lit to a minimum of 1 lux during an emergency.

Stairwells
Stairwells have increased hazards, therefore these areas should be lit to a minimum of 2 lux during an emergency.

Switch Dimming

With Switch Dimming it is possible to create lighting systems that can be easily switched and dimmed at low cost. It involves using standard mains retractable switch for lighting controls. The different switching and dimming functions are performed depending on the operating status at the time and how long the switch is pressed.

A short press on the switch, switches the connected driver to turn the fitting on or off.

A long press on the switch will dim the connected driver up or down depending on its current operating status.

Analogue Dimming

Analogue dimming uses a separate control wire to notify the driver that the power of the LEDs should be changed. The separated control signal is a DC (direct current) and can be adjusted from 1 up to 10 volts, the voltage level is interpreted by the driver to set the LED power.

1-10V Method of Control

The 1-10V method of control is a low current system (typically 1mA) meaning it can be run along relatively thin cables with little voltage drop and depending on dimmer manufacturer recommendations. This allows for up to 50 LED dimmable drivers on one wall mounted dimmer.

DALI Dimmable

GRID - What is Digital Addressable Lighting Interface?
It is a testing and control system, programmed by the DALI controller/system. The fitting will enter a self-commissioning phase; DALI Units also offer status feedback reports to the system. Once the module has received a valid DALI command, the module enters DALI mode and adopts default settings for test pre-programmed.

DALI Control System
DALI is a digital communications protocol that was developed for the lighting industry. A separate control wire of BUS is used to send digital information to light fittings and allows the individual light fittings and sensors to communicate with an advanced lighting control system. Although DALI is a standard protocol beware of mixing components between manufacturers with our testing first. Along with the correct LED Driver the DALI system requires additional control equipment including DALI BUS controllers, power supplies, sensors and user interfaces.
