Optical products
Lamps including high-luminosity LEDs were developed and produced in large quantity, becoming commonplace, in an erawhen industry-wide safety standards were not the norm. The evaluation and control of optical-radiation hazards from lamps and lamp systems is a far more complicated subject than addressing tasks performed by single-wavelength devices such as laser products. The required radiometric measurements are quiteinvolved, for they do not deal with the simple optics of a point source, but rather with anextended source that may or may not be altered by diffusers or projection optics. In addition, thewavelength distribution of a lamp may be altered by ancillary optical elements, diffusers,lenses, and the like, as well as variations in operating conditions.
There are well-known optical-radiation hazards associated with some lamps andlamp systems, for example as delineated in IEC 62471.TÜV Rheinland Taiwan can test in accordance with IEC 62471 to provide evaluation of potential radiation hazards associated with various lamps and lampsystems. |
