Recently, I learned from the Beijing Lighting Society that the Fire Department of the Ministry of Public Security is working on the establishment of a national standard for fire emergency lighting systems that is in line with international standards. Compared with the current national standard GB17945 for fire emergency lighting, the new standard is in addition to "related power lights" and "children." In addition to the contents of the power-type fire emergency light, the two parts of the "Special Requirements for Centralized Power Supply Fire Emergency Lights" and "Special Requirements for Centralized Control Fire Fighting Emergency" are included. The implementation of the new standard will bring new impact to the emergency light industry. In 2001, in order to adapt to the new situation of China's accession to the WTO, the Ministry of Public Security canceled the provincial record management system for emergency lights and turned it into a national license, which accelerated the development of the emergency light industry and intensified competition in the emergency light market. . According to statistics, in addition to Qinghai and the Tibet Autonomous Region, all other provinces have emergency light manufacturers, especially fire emergency light manufacturers, and now more than 1,500 types of valid type approval certificates. With so many companies and so little market share, the competition is fierce. Although there are many domestic manufacturers of emergency lights mainly for domestic sales, it is difficult to make breakthroughs in the market due to the small scale, fierce market competition and limitations of their own strength. Some emergency lamp manufacturers have fought for market share in order to compete for market share. The industry believes that the price increase of raw materials and the price reduction of products will make the emergency light industry soon become a low-profit industry like the electronic energy-saving lamp industry. Counterfeiting is also a common phenomenon in the emergency light industry. There are various ways to make fakes, or to induce him to fake, or to cut corners, to earn the difference. Some of the counterfeiters also use counterfeit products to steal the columns and deceive customers. It is understood that the "Regulations on the Supervision and Administration of Fire Products" newly formulated by the Fire Department of the Ministry of Public Security is scheduled to be implemented in January next year. It will strictly supervise fire products including emergency lights, and increase the sampling of product circulation areas and engineering use units. Increase the penalty for unqualified products.
