Remarks concerning optical radiation safety*
At low forward current (<150 mA), and continuous operation, this LED may be classified as LED
product Class 2, according to standard IEC 60825-1:A2. Class 2 products emit in the visible region,
damaging exposure is usually prevented through avert reactions including blink reflex. It can be
expected that these reactions provide sufficient protection under reasonably predictable conditions.
This also implicates a direct observation of the light beam by means of optical instruments.
If intended to operate at higher current, this product should be classified as LED product Class 2M,
according to standard IEC 60825-1:A2. Class 2M products are safe to eyes and skin under normal
conditions, including when users view the light beam directly. These products emit in the visible
region and it is presumed that the human blink reflex will be sufficient to prevent damaging
exposure, but if the beam is focused down, damaging levels of radiation may be reached.
Therefore, users should not incorporate optics that could concentrate the output into the eyes.
*Note: Safety classification of an optical component mainly depends on the intended application
and the way the component is being used. Furthermore, all statements made to classification are
based on calculations and are only valid for this LED “as it is”, and at continuous operation. Using
pulsed current or altering the light beam with additional optics may lead to different safety
classifications. Therefore these remarks should be taken as recommendation and guideline only.
Notes
• The mentioned specifications are for reference purpose only and subjected to change without
prior notice.
• All measurements carried out on blank aluminium heat sink, S = 180 cm², passive cooling.
Measurement results and curve characteristics obtained with other heat sinks may differ.
• Do not view directly into the emitting area of the LED during operation!
• This high power LED must be cooled!
