What is the IEC code for LED lights ?

The IEC code is divided into four main categories, each representing a different level of hazard. These categories are based on the potential risks associated with the exposure of the human eye and skin to optical radiation emitted by the LED light.

The first category, "TUV-X, " is the most severe and applies to products with high energy requirements and high levels of risk. The second category, "TUV-A, " is the most mild and applies to products with moderate energy requirements and lower levels of risk. The third category, "TUV-B, " is moderate and applies to products with low energy requirements and lower levels of risk. The fourth category, "TUV-C, " is the least severe and applies to products with low energy requirements and low levels of risk.

Exposure Limits:

The IEC code also sets limits on the amount of time that a person can be exposed to the full intensity of the LED light without experiencing any adverse effects. This is expressed in a unit of time called the " exposure unit" (EU). The exposure limit for LEDs is typically expressed in the form of a percentage of the person's exposure to the full intensity of the light for a given duration of exposure.

Pulse Duration:

The IEC code also specifies the duration of the pulse that can be detected in the human eye after exposure to an LED light. This is expressed in the " pulse duration" (PD) unit, which is the time required for the light to flicker on and off.

Source Distance:

The IEC code also specifies the distance from the LED light source to the person's eye when the light is viewed. This is expressed in the " source distance" (SD) unit, which is the distance from the light source to the person's eye.
