IEC/TR 62778:2012 provides clarification and guidance for the assessment of blue light hazard of all lighting products that have the main emission in the visible spectrum (380 nm to 780 nm). By optical and spectral calculations, it is shown what the photobiological safety measurements relate about the product and, if this product is intended to be a component in a higher level lighting product, how this information can be transferred from the component product (the LED package, the LED module, or the lamp) to the higher level lighting product (the luminaire).

Electronics Cooling magazine has been providing a technical data column since 1997 with the intent of providing you, the readers, with pertinent material properties for use in thermal analyses. We have largely covered the most common materials and their associated thermal properties used in electronics packaging.
