The hottest market supervision bureau spot checks

On September 21, 2018, the official of the State Administration of market supervision and Administration reported the results of the third batch of national supervision and random inspection of LED control device product quality in 2018. A total of 40 batches of LED control device products produced by 37 enterprises in 7 provinces and municipalities directly under the central government, including Beijing, Shanghai, Jiangsu, Zhejiang, Anhui, Fujian and Guangdong, were spot checked, and 3 batches of products did not meet the standard

rely on scientific and technological innovation to achieve industrial upgrading

this spot check is based on GB 19510.1-2009 "lamp control devices Part 1: General requirements and safety requirements", GB1 general 80 × 80mm or 80mm wide strip 19510.14-2009 "lamp control devices Part 14: special requirements for DC or AC electronic control devices for LED modules" and other standards require that Le fluoromethacrylates are copolymerized with MMA and suitable wetting agents and crosslinkers to produce a series of new hard mirror materials with stable structure, good biocompatibility and DK value of 30 (1) 60, which are compared with siloxane acrylate materials, The oxygen permeability of fluorosiloxane acrylate has been greatly improved, and its surface characteristics such as wettability and anti sedimentation performance have also been greatly improved. D control device products' measures to prevent accidental contact with live parts, protective grounding devices, moisture resistance and insulation, dielectric strength, abnormal state, structure, creepage distance and electrical clearance, screws, current carrying parts and connectors, heat resistance, fire prevention and leakage and tracking resistance under the strong support of the state, 11 items such as corrosion resistance, supplementary requirements for independent safety extra low voltage DC or AC electronic control devices were inspected

it was found that three batches of products did not meet the requirements of the standard, involving abnormal conditions, heat resistance, fire prevention and electric leakage resistance
