Determining light output in emergency operation

c

24 / 38

1.

2.

3.

To determine the light output in emergency operation the following parameters are crucial:

LED forward voltage (total forward voltage of all connected LED modules)

LED current in emergency operation

Light output in emergency operation

7.1. Parameter 1: LED forward voltage

7.1.1. Total forward voltage of all LED modules

The forward voltage of a single LED module can be found in the data sheet. When calculating the total forward voltage of all LED
modules, series and parallel circuits must be handled differently:

Series circuit

Parallel circuit

The values of the individual LED modules are summed up.

The total value is the same as the value of a single LED module.

...

The total forward voltage of all connected LED modules must be within the forward voltage range of the EM converterLED ST
