What IEC 62471?
IEC/EN 62471 gives guidance for evaluating the photobiological safety of lamps and lamp systems including luminaries.
What is Photobiological safety?
The photobiological safety standard must be applied against the damage of light. to the eyes and skin and the danger of blue light, in LED lighting fixtures.
What is RG0?
Four risk groups are defined: Risk Group 0 (RG0, no risk), Risk Group 1 (RG1, low risk), Risk Group 2 (RG2, moderate risk), Risk Group 3 (RG3, high risk). The risk group depends on the maximum permissible exposure time (MPE time) assessed at a given viewing distance.
What is Photobiological testing?
Photobiology is the study of the interaction of optical radiation with living organisms. It’s especially important in understanding the effect on human eyes and skin.
What is Photobiological test?
Photobiological testing allows manufacturers to evaluate the safety of lamps and lamp systems, including luminaires.
Are light emitting diodes safe?
Traditional LEDs are generally considered safe, with no need for separate LED safety standards, as opposed to the higher-power laser diodes, which are known to cause eye hazards. LED exposures are regulated by the lamps standard (IEC/EN 62471, Photobiological Safety of Lamps and Lamp Systems).
Where are IEC standards used?
IEC Standards are often used as a basis to globally harmonize technical requirements in IEC member and non-member countries. Although IEC Standards play a critical role in developing world trade, many countries often have national differences to IEC requirements.
What is Reth in Juniper?
A redundant Ethernet (reth) interface is a pseudo-interface that includes a physical interface from each node of a cluster. A reth interface of the active node is responsible for passing the traffic in a chassis cluster setup.
Do LEDs give off UV?
Do LED Light Bulbs Emit UV Radiation? For the majority of LED light bulbs, in industrial applications and otherwise, they do not give off UV radiation. In earlier incarnations of LED lighting the reason they did not emit UV radiation was their inability to give off white light.
What is the function of IEC?
These functions include promoting voter education; registering voters and political parties; reviewing electoral legislation; allocating seats to constituencies and delineating administrative voting areas; and disbursing public funding to, and regulating private funding of, political parties.
What is the purpose of the IEC?
What is the purpose of IEC standards?
IEC International Standards are essential for quality and risk management; they help researchers understand the value of innovation and allow manufacturers to produce products of consistent quality and performance.
