IEC 60950 Photobiological Testing of Information Technology Lighting Equipment
The International Electrotechnical Commission (IEC) standard IEC 60950 is a critical document that provides essential guidelines for ensuring the safety and reliability of information technology equipment, including lighting devices. This standard aims to protect users from potential hazards associated with photobiological risks.
The primary focus of IEC 60950 is on the evaluation of photobiological safety in IT equipment, which includes various types of lighting such as LED lights used in computers and other electronic devices. Photobiological safety testing ensures that the light emitted by these products does not exceed acceptable levels of photobiological hazard.
Photobiological hazards can be categorized into three classes: UVA (ultraviolet), UVB, and blue light. These classifications are based on the potential for damage to living tissue or eyes when exposed to light from a specific source. According to IEC 60950, the photobiological safety of IT equipment is evaluated by measuring the emitted light energy in nanowatts per square centimeter (nW/cm²). The standard specifies permissible exposure limits (PELs) for different classes and types of lighting.
For LED lights used in information technology products, compliance with IEC 60950 ensures that the equipment meets stringent safety requirements. This is crucial not only for protecting users but also for ensuring that devices comply with international regulations and standards.
The testing process involves several steps, including specimen preparation, calibration of measurement instruments, and actual testing using specialized photobiological safety meters. Specimen preparation typically includes cleaning and positioning the LED light in a standardized manner to ensure accurate measurements. Calibration ensures that the measuring equipment is precise and consistent across multiple tests.
During the test, the emitted light from the IT lighting device is measured under specific conditions. The measurement process involves placing the specimen at a fixed distance from the photometer and recording the light intensity in different wavelengths. This data is then analyzed to determine whether the product complies with IEC 60950.
The testing apparatus used for this purpose includes high-precision photometers capable of measuring light energy across various wavelength ranges, including UVA, UVB, and blue light. The equipment must be regularly calibrated to ensure accurate results. Compliance with IEC 60950 is crucial for manufacturers as it ensures that their products meet stringent safety standards.
Compliance with IEC 60950 not only enhances product safety but also contributes to environmental sustainability by reducing the risk of accidental eye injuries and other photobiological hazards. By ensuring that IT lighting equipment meets these stringent safety requirements, manufacturers can help protect users while minimizing potential risks.
In conclusion, IEC 60950 is a vital standard for ensuring the photobiological safety of information technology lighting equipment. Compliance with this standard ensures product safety and contributes to environmental sustainability by reducing the risk of accidental eye injuries and other photobiological hazards.
