INTRODUCTION

1.1. System overview
Brightness levels of today’s LEDs are opening the door for
usage of LEDs in general lighting applications requiring
high lumen output levels. Building an LED-based luminaire
poses a new set of technical challenges, among them new
optical requirements, providing adequate thermal manage-
ment for stable operation and lastly dealing with the ever-
improving performance of LEDs.

OSRAM’s PrevaLED

family of LED light engines addresses

the challenges of LED-based lighting while at the same
time giving the user great performance and ﬂ exibility.

The PrevaLED

Core Z2 series of light engines is ideally

suited for use in reﬂ ector-based, rotation-symmetric
applications such as downlights or spotlights. These light
engines provide several convincing beneﬁ ts in the
application:

• PrevaLED

Core Z2 light engines are available as a sys-

tem of matching LED modules and ECGs and deliver
maximum performance at very high levels of efﬁ ciency.

• These light engines provide superior optical perfor-

mance, both in terms of their optical efﬁ ciency as well
as their high quality of light (color rendering).

• A wide range of lumen packages (currently available

from 800–5000 lm) allows addressing a wide range of
applications based on a single platform. This platform
allows, for example, the operation of a sequence of
spotlights – ranging from halogen-class up to HID levels
– in a row, while at the same time creating a homoge-
neous overall impression for the end user.

• Thanks to their high thermal and optical performance,

luminaires based on PrevaLED

Core Z2 light engines

can be realized with minimized size of required heat sink
and reﬂ ector, giving the user greater design ﬂ exibility.

• PrevaLED

Core Z2 light engines provide standardized

interfaces for the user, in particular by deﬁ ning stable
lumen packages over time. Independent of future in-
creases in LED efﬁ cacy, the luminous ﬂ ux of an individual
LED module will remain constant, but at lower power
consumption. In this way, a luminaire designed on the
PrevaLED

Core platform will automatically beneﬁ t from

efﬁ cacy improvements without needing a lengthy and
costly redesign of the base construction.
