The shiny LED lights are very popular, including our adults, but the children who are not curious can't resist the temptation and can't help touching the Christmas lights with their hands to cause burns. Anyone who knows common sense knows that LED lights will generate heat after long-term use, and the temperature will gradually rise. Regular manufacturers can control the temperature below 40 degrees, but through observation, many LED lights on Christmas trees are not produced by manufacturers. Most of the logos are produced by cottage manufacturers, because they are cheap. In order to reduce costs, merchants often choose cheap LED lights for decoration. Anyway, they were removed in a few days, ignoring safety factors.
Harbin LED lamp scald incident: On December 7th, parents took their 2-year-old daughter to a shopping mall. A beautiful Christmas tree was placed in the shopping mall, decorated with decorative lights around it, and they looked so beautifully decorated. They planned to give their daughter a Christmas tree. Before taking a picture, I didn't expect that the time I took the picture, my daughter's hand was burnt (the LED light on the Christmas tree was touched by hand). The child's hands blistered, and the child cried in pain. My mother tried to touch the light bulb, but when you touched it, your hand shrank back and felt the temperature was particularly high. Seeing the blisters burned on the child's hand, he had to pick up the child and go to the bathroom, rinse with cold water to relieve the child's pain. Now as long as her daughter sees something like a glow, she won't touch it. Left a psychological shadow for the child.
Throughout the development process of China's street lamp industry, although the national macro-control policy continues to drive the sustainable growth of the industrial economy, but behind the rapid economic growth, the technology of China's street lamp industry, which is still in the development stage, still needs to be improved. The product market also needs to be expanded.
As an important hub for the horizontal development of China's street lighting industry, China Street Light Network has continuously optimized the industrial structure based on the publicity and guiding advantages of its network platform during the period of strategic opportunities for the development of China's street lighting industry, and based on industry information, exhibition information, product supply and demand Supported by other professional modules, it accelerates the pace of industry system innovation and technological innovation.
China Street Light Network will aim to develop the sustainable development path of China's street light industry, analyze the market and analyze the market from a professional perspective, and strategically adjust the situation to help the perfect transition of China's street light industry from the development period to the mature period.
