Notes

The evaluation of eye safety occurs according to the standard IEC 62471:2006 (photo biological safety of

lamps and lamp systems). Within the risk grouping system of this IEC standard, the LED speci󰘰ed in this

data sheet falls into the class exempt group (exposure time 10000 s)
sure time, conditions of the eye pupils, observation distance), it is assumed that no endangerment to the
eye exists from these devices. As a matter of principle, however, it should be mentioned that intense light

sources have a high secondary exposure potential due to their blinding e󰘯ect. When looking at bright light

sources (e.g. headlights), temporary reduction in visual acuity and afterimages can occur, leading to irrita­tion, annoyance, visual impairment, and even accidents, depending on the situation.

Subcomponents of this LED contain, in addition to other substances, metal 󰘰lled materials including silver.
Metal 󰘰lled materials can be a󰘯ected by environments that contain traces of aggressive substances. There-

fore, we recommend that customers minimize LED exposure to aggressive substances during storage, pro­duction, and use. LEDs that showed visible discoloration when tested using the described tests above did
show no performance deviations within failure limits during the stated test duration. Respective failure limits
are described in the IEC60810.

Glossary

1)

Testing temperature: TA = 25°C

2)

Typical Values: Due to the special conditions of the manufacturing processes of LED, the typical data

or calculated correlations of technical parameters can only re󰘱ect statistical 󰘰gures. These do not nec­essarily correspond to the actual parameters of each single product, which could di󰘯er 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.

3)

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

dimensions are speci󰘰ed in mm.
