Within the risk grouping system of this IEC standard, the LED 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.

Product 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. 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. 11 Version 1.3 | 2018-06-05 SFH 4557 Glossary 1) Radiant intensity:Measured at a solid angle of = 0.01 sr 2) Reverse Operation:Reverse Operation of 10 hours is permissible in total. Continuous reverse operation is not allowed. 3) Total radiant flux:Measured with integrating sphere. 4) Thermal resistance:junction ambient, mounted on PCboard (FR4), padsize 16 mm each 5) Typical Values:Due to the special conditions of the manufacturing processes of LED, 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 differ 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. 6) Testing temperature:TA = 25C 7) Tolerance of Measure:Unless otherwise noted in drawing, tolerances are specified with 0.1 and dimensions are specified in mm. 12 Version 1.3 | 2018-06-05 SFH 4557 Published by OSRAM Opto Semiconductors GmbH Leibnizstrae 4, D-93055 Regensburg www.osram-os.com (c) All Rights Reserved. 13 Version 1.3 | 2018-06-05
