Core Z3 LED modules | Optical considerations

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).

2.2 Reﬂ ector design

High luminous intensities (1.5–4.5 Mcd/m

) 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 simu-

lation 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).
