Glossary

1)

Brightness: Brightness values are measured during a current pulse of typically 45 ms, with an internal

reproducibility of ±8 % and an expanded uncertainty of ±11 % (acc. to GUM with a coverage factor of

k = 3).

2)

Reverse Operation: This product is intended to be operated applying a forward current within the

specified range. Applying any continuous reverse bias or forward bias below the voltage range of light

emission shall be avoided because it may cause migration which can change the electro-optical char-

acteristics or damage the LED.

3)

Chromaticity coordinate groups: Chromaticity coordinates are measured during a current pulse of

typically 45 ms, with an internal reproducibility of ±0.005 and an expanded uncertainty of ±0.01 (acc. to

GUM with a coverage factor of k = 3).

4)

Forward Voltage: The forward voltage is measured during a current pulse of typically 28 ms, with an

internal reproducibility of ±0.05 V and an expanded uncertainty of ±0.1 V (acc. to GUM with a coverage

factor of k = 3).

5)

Thermal Resistance: Rth max is based on statistic values (6σ) used for Derating.

6)

Typical Values: Due to the special conditions of the manufacturing processes of semiconductor devic-

es, the typical data or calculated correlations of technical parameters can only reflect statistical figures.

These do not necessarily correspond to the actual parameters of each single product, which could dif-

fer from the typical data and calculated correlations or the typical characteristic line. If requested, e.g.

because of technical improvements, these typ. data will be changed without any further notice.

7)

Luminescence: The red conversion material used in this LED has a significantly slower response time

compared to the green conversion material and the blue emitter.

The red converter will fluoresce with a rise and decay time of about 8ms. This may result in a visible

red sparkling effect if operated in pulse-width-modulation mode. In order to mitigate such effect please

consider DC mode operation or apply appropriate timing in combination with circuit design.

8)

Characteristic curve: In the range where the line of the graph is broken, you must expect higher differ-

ences between single devices within one packing unit.

9)

Tolerance of Measure: Unless otherwise noted in drawing, tolerances are specified with ±0.1 and

dimensions are specified in mm.

10)

Tape and Reel: All dimensions and tolerances are specified acc. IEC 60286-3 and specified in mm.
