THERMAL CONSIDERATIONS

4.5. ECG thermal considerations

The installation of the ECG must ensure that the maximum

temperature at the T

is not exceeded. Further details on

thermal considerations for OPTOTRONIC

devices can be

found in the technical guide for OPTOTRONIC

, available

at: www.osram.com/optotronic.

4.6. Thermal management and lifetime

The PrevaLED

Core Z2 has a lifetime of 50,000 h

(L70B50*). If the temperature is exceeded, the speciﬁ ca-

tion is left and, after further heat-up, the LED module is

switched off. Liftetime information (see datasheet) as well

as guarantee information for LED modules combined with

ECG at: www.osram.com/prevaled-core.

*) L70B50 deﬁ nition: After 50,000 h, at least 50 %

of the observed LED modules still show 70 % of

the initial luminous ﬂ ux.

**) The guarantee conditions can be found at

www.osram.com/system-guarantee.

4.7. Zhaga – thermal interface

Veriﬁ cation of thermal interchangeability according to Zhaga:

Determine the thermal resistance

of the luminaire

Choose an applicable module
