Principles
The main components of the system are a spectroradiometer, a retina radiance meter for measuring spectral radiance, a light receiver for measuring spectral irradiance, a motorized two-axis rotation goniometer for measuring spatial maximum exposure value, an optical rail for measuring at 200mm and 500lx condition of general lighting sources, and calibrated sources of spectral irradiance with the wavelength from 200nm to 3.
IEC62471 states that this system is useful for determining the maximum exposure to a given hazard class in a given space and corresponding apparent source, for measuring weighted radiance within related 1.7mrad to 110mrad fields of viewing, and for measuring irradiance at the specified receiving angles.
Following the IEC-CTL decision for laboratory needs, it may use the system to assess optical radiation safety addressing IEC62471.
Testing to laser radiation safety standards: FDA/CDRH 21CFR and IEC 60825-1
Even though they have numerous technical advantages, Lasers can present new safety risks. Under some conditions, exposure to laser radiation may cause eye or skin damage. Two laser product safety standards serve the primary purpose of helping to ensure that a product has appropriate safeguards to protect those who use, maintain, and service that product. These standards are known as FDA/CDRH 21CFR within the United States and IEC 60825-1 outside of the United States.
In addition, in the year 2021, the European Union published two additional safety regulations linked to laser products:
Safety of Laser Products, Part 1: EN 60825-1:2014+A11:2021 Classification and Requirements for Equipment: When compared to the IEC 60825-1, the additional safety concerns included by Amendment 11 to EN 60825-1:2014 for laser products include:
Lidar — an up-and-coming laser technology
The technology of Lidar, a sort of laser radiation, is undergoing a revolution in various sectors, including robotics, autonomous cars, and surveying. This technology helps automate a wide variety of day-to-day activities, including things like driving, monitoring inventories, and mapping. Although Lidar is not a brand innovation, the fact that these applications make it more appealing to consumers drives more interest in it.
The environment is scanned for potential hazards using lidar technology, which works by firing off bursts of laser radiation into the atmosphere and measuring the time that passes before the radiation reflects. On the other hand, the laser radiation that is released may cause health and safety problems due to its impact on the human body, especially the eyes. To make things even more complicated, radiation is often invisible. To fulfill its purpose, it must send it into free space, where innocent bystanders, such as pedestrians and others, may be subjected to it without realizing it.
LISUN can offer assistance in the process of evaluating and testing their products by the relevant laser radiation safety standards, which are known as FDA/CDRH 21CFR Part 1040 in the United States and IEC 60825-1 in countries outside of the United States. Stakeholders and consumers may gain a greater understanding of the possible laser threats posed by Lidar with the aid of these assessments. We can assist manufacturers in any way we can, whether they have questions for the laser specialists at LISUN, want us to assess the possible danger by testing and validating the laser classification, or want LISUN to certify the device as conforming to these requirements.
You may accomplish what you set out to do with the assistance of our worldwide network of laser labs and experts. We can assist you at every stage of the process to expedite the introduction of your product to the market and assist you in navigating the intricate worldwide standards and regulations.
Testing to LED radiation safety standards: ANSI and IEC 62471
Concerns about the photobiological effects of LEDs continue to grow with the widespread use of these lights and the expansion of their functional capacities. One notable illustration of these problems is the blue light emitted by electronic devices such as phones and screens. The standards known as IEC 62471 and RP-27, administered by the American National Standards Institute (ANSI), discuss the photobiological dangers posed by LEDs. We do the necessary testing and analysis to establish the Risk Group danger categorization of a product following the relevant requirements.
The LEDs that are used in bar code imaging, as well as the LEDs that are utilized in security cameras, are both evaluated by our optical radiation safety test system (EN62471-C). Our reports provide manufacturers with the information they need to prove compliance with LED radiation safety guidelines.
Testing to UV radiation safety standards: ANSI, ACGIH, and IEC 62471
The ultraviolet (UV) spectrum includes light with sources such as LEDs, lamps, and lasers. Although mostly undetectable to the naked eye, this ultraviolet radiation poses a significant risk to photobiological systems, including the skin and the eyes.
In addition, several UV sterilization devices are now available in the modern market. The amount of ultraviolet (UV) radiation emitted by these items has to be evaluated and analyzed. To assign a product to a Risk Group and ensure that it does not exceed any necessary exposure limits, UL Solutions may assess the photobiological safety of the UV radiation.
The ANSI-based RP-27 series and the IEC 62471 standards are only two examples of the many safety standards covering the risks associated with ultraviolet radiation.
It may test all these UV radiation standards in our optical radiation safety test system (EN62471-C). We provide data in a usable manner, improving turnaround times and opening access to international markets.
FAQs
Which LED must meet radiation safety standards?
The ANSI RP-27 and IEC 62471 standards outline the minimum radiation protection levels for LED lighting. The photobiological (how light interacts with living things) consequences of radiation exposure to the skin and the eye are taken into account in these guidelines. LED radiation classification, labeling, manual user statements, etc., are all addressed in these norms.
In what ways may I be exposed to harmful radiation from a product’s LEDs?
Following the Risk Group, labeling requirements are included in the LED radiation standards ANSI RP-27 and the IEC 62471 series. While IEC 62471 does not include any labeling recommendations, the accompanying Technical Report IEC/TR 62471-2 (“Photobiological safety of lamps and lamp systems – Part 2: Guidance on manufacturing requirements pertaining to non-laser optical radiation safety”) does.
How can the danger of a product’s LED radiation be transferred?
A Risk Group grade is given to LED radiation based on how well it meets the safety guidelines for LED radiation. Risk Group Exempt, Risk Group 1, Risk Group 2, and Risk Group 3 are the four categories of potential danger. To put it simply, Risk Group Exempt is the safest, and Risk Group 3 is the most dangerous. Increased precautions are often associated with products in higher Risk Groups.
LED Risk Group |
Description |
Exempt |
There is no photobiological risk from this light source. |
1 |
As a result of natural limits imposed by behavior, the lamp/LED poses no threat. |
2 |
The aversion reaction (head tilt or eye blink, for example) to excessively intense light sources and temperature discomfort are not threats posed by the lamp/LED. |
3 |
Even short exposure to the lamp/LED might be dangerous. |
