The national standard for "Colorimetry Part 3: CIE Tristimulus Values" drafted with the participation of Good News I Liyang Optoelectronics has been officially released!


Great news! Recently, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China (AQSIQ) released the national standard "Colorimetry Part 3: CIE Tristimulus Value". Shenzhen Liyang Optoelectronics Co., Ltd., as one of the main drafting units, has made important contributions to the formulation of this national standard.

According to the "National Standard Announcement of the People's Republic of China" (No. 7 of 2023) issued by the State Administration for Market Regulation and the National Standardization Administration, the national standard "Colorimetry Part 3: CIE Tristimulus Values" is under the jurisdiction of TC224 (National Lighting Appliance Standardization Technical Committee) and executed by TC224SC4 (Lighting Basic Branch of National Lighting Appliance Standardization Technical Committee), with the competent department being the China Light Industry Federation. The standard was released on August 6, 2023 and will be implemented on March 1, 2024. The standard number is GB/T 20147.3-2023.

As a leader in the high-power LED lighting industry, Liyang Optoelectronics has always focused on the research and innovation of optoelectronic technology, constantly challenging technological boundaries and pursuing excellence.
