Today, ceiling lamps are becoming the new darling of people's homes. Consumers should consider several aspects when shopping: 1. In large stores, purchase products with the “Three Guarantees†commitment and purchase lamps with the CCC certification mark. 2, depends on the product identification is complete, formal products should be identified: trademark and factory name, product model specifications, rated voltage, rated frequency, rated power. 3, to see if the lamp power cord has CCC safety certification mark. 4, see if the lamp charged body is exposed, the light source into the lamp holder, the finger should not touch the live metal lamp. 5. Types of electric shock protection for ceiling lamps can be classified into 0, I, II and III types. Type 0 lamps have poor safety. They rely on basic insulation as protection against electric shock. In case of basic insulation failure, electric shock hazards are easily generated. The protection against electric shock of Class I lamps not only depends on the basic insulation, but also includes additional safety measures. That is, the easy-to-access conductive parts are connected to the grounding protection wires so that the accessible conductive parts will not cause the grounding of the live lighting when the basic insulation fails. There is a grounding symbol beside the terminal. It should be noted that the metal housing of the Type I lamp should be effectively grounded. If the lamp replacement can touch the ballast, the ballast should also be effectively grounded. The protection against electric shock of Type II lamps not only depends on the basic insulation, but also has additional safety measures, such as double insulation or reinforced insulation. In case of basic insulation failure, it can also rely on supplementary insulation protection. The protection against electric shock of Class III lamps depends on the power supply being a safety extra-low voltage, and no voltage exceeding the safety extra-low voltage is generated inside the lamp. Therefore, you should try to buy Class I, Class II, and Class III lamps.
