PrevaLED® Core Z3 LED modules | Introduction

1 Introduction

1.1 System overview

Building an LED-based luminaire poses a new set of tech­nical challenges, among them new optical requirements,
providing adequate thermal management for stable
operation and lastly dealing with the ever-improving
performance of LEDs. Nevertheless, LED technology also
provides an unknown wealth of possibilities, opening up un­precedented levels of performance.

This technical application guide will support you in tackling
the challenges and taking full advantage of all opportunities
PrevaLED

®

Core LED modules have to offer.

Focussing on continuous improvement of performance and
costs, OSRAM has introduced its new generation
of Zhaga spotlight LED modules: PrevaLED
together with the dedicated on/off and intelligent
OPTOTRONIC

®

electronic control gear (ECG) ranges.

®

Core Z3,

Future-proof concept

To allow for a smooth transition to this new generation
of the PrevaLED
remained the same:

— System approach with OPTOTRONIC

®

Core series, crucial features have

®

ECGs

— Form factor and mechanical/optical interfaces
— Compatibility with off-the-shelf accessories

according to Zhaga book 3.

Of course, important improvements
have been realized as well:

— Effi cacy of the modules
— 5 000-lm package
— Price position
— Power supply/LED module interface – fi t to standard

cables and standard constant-current power supplies
(on/off and intelligent)

Applications

The PrevaLED

®

Core series of LED modules is ideally
suited for use in refl ector-based, rotation-symmetric
luminaires (such as tracklights, cardans, and downlights) in
shop, hospitality, decorative or offi ce applications.

2 Optical considerations

2.1 Light distribution

The light distribution of the LED module is shown in the
graph below. PrevaLED

®

Core Z3 LED modules create

a beam angle of 115° FWHM (full width at half maximum).

C 0°

15°

2.2 Refl ector design

High luminous intensities (1.5–4.5 Mcd/m2) are the key
factor for LED-based lamps and luminaires in the area of
refl ector applications such as spotlights. For this purpose,
light sources with small light-emitting surfaces and a high
luminous fl ux – as realized in the PrevaLED

®

Core Z3 – are
required, because in such combinations, the light can be
collimated especially well with refl ectors.

®

The PrevaLED

Core Z3 is equipped with a surface that
emits light evenly and makes the use of diffuser materials
unnecessary due to its high level of homogeneity. The
minimized light-emitting surface (LES) and a positioning of
the refl ector close to the LES allows for an improved optical
handling. Generally, the properties of the PrevaLED

®

Core Z3
help to avoid roughness and facets, allowing for very small
total beam angles of 10° or less.

OSRAM provides mechanical (3D fi les) and optical simu­lation data (ray fi les) to support customized refl ector
designs. Mechanical fi les can be downloaded at

www.osram.com/prevaled.

Ray fi le data are available upon request through your
sales partner. Available ray fi le formats are ASAP, SPEOS,
LightTools and Photopia (all bi nary).

— A parabolic refl ector shape is used.
— A fi ne facet structure is applied as it should always

be used for CoB LEDs. The impact on the narrowest

possible beam angle is small.

— A purly specular refl ectance of 85 % is assumed.
— The collimation strength values cd/lm refer to the

LED module fl ux.

— Data values in red correspond to a refl ector with an

extremely large diameter/height ratio D/H > 2 (cut-off

angle > 45°). This is not recommended with respect

to glare.

— Illuminance values are the maximum values in the spot

center in 2 m distance to the refl ector.

The PrevaLED® Core Z3 can be used with secondary optics.
Zhaga-compliant off-the-shelf solutions can be used with the
LED module. For optics support, you can fi nd suppliers via
OSRAM's LED Light for You network: www.ledlightforyou.com.

PrevaLED

Core Z3 3D fi les including the bayonet base for
design-in are available at:

www.osram.de/prevaled-core.

2.4 Color temperature

The PrevaLED® Core Z3 series is currently available in 2 700
K, 3 000 K, 3 500 K and 4 000 K. The color coordinates
within the CIE 1931 color space are given below.

2700 K 3000 K 3500 K 4000 K

Cx 0.4585 0.4345 0.4083 0.3828
Cy 0.4104 0.4033 0.3921 0.3803

®

Within each available color temperature, the PrevaLED
Core Z3 series provides a maximum color variation of three
threshold value units (MacAdam steps). The following dia­gram shows these threshold values within the CIE 1931
color space.

2.3 Refl ector mounting

The LED modules have a clearly defi ned optical contact
area (OCA), which provides a defi ned surface for attaching
the refl ector. In this confi guration, the mounting and mecha­nical support of the refl ector must be ensured by the lumi­naire body or by suitable structures for refl ector mounting.

The following has to be considered when mounting the re­fl ector: Due to the creepage and clearance distances speci­fi ed in the norm (IEC 61347-1/U935, among others), it is re­commended to stay within the OCA values of the corres­ponding category (see PrevaLED

®

datasheet).

Additionally, a bayonet base option is provided, with the
help of which the refl ector can be attached directly to the
PrevaLED

®

Core Z3.
