SFH 4851 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 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.

SFH 4851 Glossary 1) Radiant intensity: Measured at a solid angle of Ω = 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) 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.
