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 device specified in this  data sheet fall into the class exempt group (exposure time 10000 s). Under real circumstances (for exposure 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 effect. 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 device contain, in addition to other substances, metal filled materials including silver.
Metal filled materials can be affected by environments that contain traces of aggressive substances. Therefore, we recommend that customers minimize device exposure to aggressive substances during storage, production, and use. Devices 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.

Packing
Please use the recycling operators known to you. We can also help you – get in touch with your nearest sales office. By agreement we will take packing material back, if it is sorted. You must bear the costs of  transport. For packing material that is returned to us unsorted or which we are not obliged to accept, we shall have to invoice you for any costs incurred.
Product and functional safety devices/applications or medical devices/applications OSRAM OS components are not developed, constructed or tested for the application as safety relevant component or for the application in medical devices.
OSRAM OS products are not qualified at module and system level for such application.
In case buyer – or customer supplied by buyer – considers using OSRAM OS components in product safety devices/applications or medical devices/applications, buyer and/or customer has to inform the local sales partner of OSRAM OS immediately and OSRAM OS and buyer and /or customer will analyze and coordinate the customer-specific request between OSRAM OS and buyer and/or customer.

Glossary

  1. Radiant intensity: Measured at a solid angle of Ω = 0.001 sr

  2. Brightness: The brightness values are measured with a tolerance of ±11%.

  3. 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 characteristics or damage the LED.

  4. Wavelength: The wavelengths are measured with a tolerance of ±1 nm.

  5. Forward Voltage: The forward voltages are measured with a tolerance of ±0.1 V.

  6. Total radiant flux: Measured with integrating sphere.

  7. Thermal resistance: junction ‐ ambient, mounted on PC‐board (FR4), padsize 16 mm² each

  8. Typical Values: Due to the special conditions of the manufacturing processes of semiconductor devices, 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.

  9. Testing temperature: TA = 25°C (unless otherwise specified)

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