Blue light hazard (BLH) is defined as a risk to the retina from radiation in the range of approx. 410 to 480 nm (half-width) with a maximum sensitivity at 440 nm. This high-energy blue light can cause so-called photoretintis, photochemical damage to the retina caused by degeneration of the macula (AMD; damage to the retinal […]
Hazards to the eye from LEDs, luminaires or other light sources are classified by DIN EN 62471, edition 2009-03 (Photobiological safety of lamps and lamp systems; German version EN 62471:2008; IEC 62471:2006). The hazard can be caused thermally or photochemically. The following possible damage is considered when evaluating a light source for resulting hazards: – […]
The shock and vibration resistance(shock resistance) provides information about the robustness of the mechanical structure of a device. The methods for assessing shock resistance are defined in IEC 60068-2-27. The shock load capacity is important for the operating and transportation conditions of the devices. The methods for assessing vibration resistance are defined in IEC 60068-2-6 […]
