TÜV SÜD Low Blue Light Certification is a voluntary certification program that includes type testing, initial factory inspections and post-certification supervision. At the same time, TÜV SÜD has also launched a series of TÜV Low Blue Light certification marks based on customer and global market needs, including Chinese and English certification marks and Chinese and English test reports, which intuitively show users the blue light ratio and blue light radiation level of the product.
TÜV SÜD's low blue light certified products will be more competitive in the market because it can provide users with authoritative and reliable information about the blue light characteristics of the product, helping users to identify safer and more reliable display products. In addition, with TÜV SÜD's more than 150-year history and authoritative industry influence, this certification provides more favorable conditions for brands to compete in the Chinese market.
TÜV's low blue light certification test program mainly covers a comprehensive evaluation of the blue light characteristics of display products. These tests are designed to ensure that the product effectively reduces blue light radiation during use, thereby protecting the user's eyesight and improving visual comfort.
First of all, spectral radiation testing is an important part of it. By measuring the spectral radiation of the product, the radiant intensity of the product in the blue light band is determined, so as to evaluate whether it meets the low blue light requirements. Low blue light products should have low blue light radiation to reduce potential harm to the human eye.
Secondly, blue light hazard assessment is also a critical step. By assessing the degree of harm to the human eye caused by the blue light radiation of the product, it is ensured that the product meets the low blue light standard. This helps ensure that users can enjoy a safer visual experience during use.
In addition, color temperature testing is also an essential link. Measuring a product's color temperature, i.e., the degree of warm and cold tones, helps ensure a more comfortable visual experience for low-blue light products. Typically, the color temperature of low blue light products is controlled in the warmer range, such as between 3000K and 4000K.
In addition to the core tests mentioned above, brightness uniformity testing is also an important part of TÜV's Low Blue Light certification. By evaluating whether the brightness distribution of the product light source is uniform, it can ensure that users can get a uniform visual experience at different angles of use, and further improve visual comfort.
It should be noted that TÜV Low Blue Light certification not only focuses on the blue light characteristics of the product, but also takes into account the actual use scenarios and user experience of the product. Therefore, during the actual inspection process, it is also possible to customize the test items according to the specific product to more comprehensively evaluate the low blue light performance of the product.
