Class 0 lamps are prone to leakage
It is understood that according to the categories of protection against electric shock, lamps can be classified into Class 0, Class I, Class II, and Class III. Most household lamps with two-phase plugs without grounding wire belong to category 0. Class 0 luminaires refer to luminaires whose outer casing is made of metal and has only one layer of insulation and the jacks are not grounded. When such luminaires have problems, the hands are easily exposed to conductive parts, posing a risk of electric shock. Household lamps such as desk lamps and floor lamps may move frequently. If the rubber surface of the wire is aged or damaged, it may cause electric shock to the user, resulting in a large safety hazard. In addition to the basic insulation, the Class I lamps also connect the easily accessible conductive parts to the grounding device, which is relatively safe.
According to the mandatory national standard for lamps, starting from New Year's Day this year, Class 0 lamps have been withdrawn from the production field, but products produced before January 1 and within the warranty period can still be sold in the market, that is, there is a certain transition period in the circulation field. Regarding the specific time of the transition period, the current state is not clear.
Class 0 lamps still account for the majority
Yesterday, the reporter visited Fuzhou Huiduoli and many lighting stores in the southern building materials market and found that in the market, table lamps, bracket lights, floor lamps, downlights and other portable lamps and recessed lamps, class 0 lamps still account for a large proportion. . In a lighting store in Huiduoli, the reporter saw that most of the ordinary desk lamps and floor lamps sold were two-phase and had no grounding. Most of the lamps used were easy-conducting metal poles, and the three-phase plugs were used for table lamps and floor lamps. less. At the same time, the reporter found that, whether it is a hypermarket or a small building materials store, most of the lamps are generally only marked with the manufacturer and the certificate of conformity, etc., and the production date is not indicated.
Most consumers don't know
Among the many lighting stores visited by Huiduoli and the Southern Building Materials Market reporters, the sales staff of most merchants were asked when they were asked about Class 0 lamps. Among them, the staff of the eight lighting stores were not clear when they were asked which are Class 0 lamps. The sales staff of a lighting store in Huiduoli told reporters that they are generally not sensitive to the standards of the lamps, because they are only responsible for sales. "We sell dozens of lamps and lanterns every day, and basically no customers have inquired about the safety category of lamps." Many salesmen told reporters.
The reporter interviewed a random number of consumers who bought lamps in the lighting market and found that no consumers knew the safety rating of the lamps, and it was even more unclear what was a Class 0 lamp. They think that the lamp has a certificate and the quality should be no problem.

Low temperature lithium battery refers to the working temperature under - 20 ℃,to meet different environment and temperature. YFJ company has designed a lot of this kind of Low Temperature Battery with our own advantages.
