What is photobiological risk of the strip light?

The photobiological risk classification is based on the international standard IEC 62471, which establishes three risk groups: RG0, RG1, and RG2. Here’s an explanation for each.
The RG0 (No Risk) group indicates that there is no photobiological risk under reasonably anticipated exposure conditions. In other words, the light source is insufficiently powerful or does not emit wavelengths that could cause skin or eye damage even after extended exposure.

RG1 (Low Risk): This group represents a low photobiological risk. Light sources classed as RG1 may cause eye or skin damage if viewed directly or indirectly over an extended period of time. However, under typical operating conditions, the risk of injury is low.

RG2 (Moderate risk): This group represents a moderate risk of photobiological harm. Even short-term direct exposure to RG2 light sources might cause eye or skin damage. As a result, caution must be exercised when handling these light sources, and personal protective equipment may be necessary.
In summary, RG0 indicates no danger, RG1 indicates low risk and is generally safe under normal conditions of usage, and RG2 indicates moderate risk and the need for additional care to avoid eye and skin damage. Follow the manufacturer’s safety instructions to reduce the risks associated with exposure to light sources.

LED strips must meet certain photobiological safety requirements in order to be considered safe for human use. These guidelines are intended to analyze the potential risks connected with exposure to light emitted by LED strips, notably their effects on the eyes and skin.
To pass photobiological safety regulations, LED strips must meet several critical conditions, including:
Spectral Distribution: LED strips should emit light in certain wavelength ranges to reduce the danger of photobiological risks. This involves reducing the emission of potentially damaging ultraviolet (UV) and blue light, which have been shown to have photobiological impacts.

Intensity and Duration of Exposure: LED strips should be configured to keep exposure to levels that are regarded acceptable for human health. This includes regulating the luminous flux and ensuring that the light output does not exceed the acceptable exposure limits.

Compliance with Standards: LED strips must meet applicable photobiological safety standards, such as IEC 62471, which gives guidance for assessing the photobiological safety of lamps and light systems.
LED strips should come with appropriate labeling and instructions that alert consumers about potential photobiological dangers and how to use the strips properly. This may include suggestions for safe distances, exposure times, and the usage of protective equipment.
By achieving these standards, LED strips can be considered photobiologically safe and used with confidence in a variety of lighting applications.
