Two plugs ≠0 type lamps look at the nameplate is the key
The mandatory national standards for lamps and lanterns will be implemented on January 1 next year. The Class 0 lamps with the lowest safety level will gradually withdraw from the market. Most of the household lamps with no plugs and grounding wires are mostly Class 0 lamps. Class 0 lamps, such as bracket lights, ceiling lamps, table lamps, floor lamps, downlights, etc., accounted for a large proportion. Class 0 lamps do not have a grounding protection line, so there is a hidden danger in terms of safety.
According to numerous media reports, although the 0-type lamps are delisting, many manufacturers and merchants do not pay enough attention to this, and consumers are confused about how to classify lamps. Then, when buying a lamp in 2009, how do you identify the type 0 lamps? The reporter consulted the relevant materials and communicated with people in the industry to explain in detail how to identify Class 0 lamps.
The lamps are classified according to the safety level, and the class 0 lamps are delisted in 2009.
According to the protection against electric shock, the lighting products are divided into the following four categories. The higher the level, the higher the security performance. The 0-class luminaire with the lowest safety performance will be delisted in 2009.
Class 0 lamps: rely on basic insulation as protection against electric shock, and only insulate the pvc outer packaging of the wires. In the event of failure of the basic insulation, it may result in electric shock and fire hazard. Protection against electric shock has to rely on the environment.
Class I luminaires: Protection against electric shock not only relies on basic insulation, but also includes additional safety measures, that is, connecting accessible conductive parts to protective earthing conductors in fixed lines, so that accessible conductive parts fail in the event of basic insulation failure. Not to be charged. (0 type lighting + ground wire)
Class II luminaires: Protection against electric shock not only relies on basic insulation, but also has additional safety measures, such as double or reinforced insulation, but without grounding or protection depending on the installation conditions.
Class III luminaires: The power supply used is a safety extra low voltage, and the inside of the luminaire does not generate a low voltage higher than SELV (36v): the mains is converted to a low voltage of 36v (plus transformer).
