1. In the big store, buy the products that have the promise of “Three Guarantees†and purchase the lamps with the CCC certification mark.
2. Look at it when you buy it. At first glance, the product identification is complete. The identification of regular products is often more standardized. It should be labeled: trademark and factory name, product model specification, rated voltage, rated frequency and rated power. Second, look at the lamp power cord for CCC safety certification mark, the cross-sectional area of ​​the external wire should be ≥0.75mm2. Third, look at whether the charged body of the lamp is exposed. After the light source is installed in the lamp holder, the finger should not touch the charged metal lamp cap.
3. Select a higher category of protection against electric shock: According to the type of protection against electric shock, ceiling lamps can be classified into Class 0, Class I, Class II and Class III. Type 0 lamps are less secure and should be purchased as far as possible for Class I, Class II and Class III lamps.
Class 0 lamps rely on basic insulation as protection against electric shock. In case of basic insulation failure, electric shock hazard is likely to occur.
The protection against electric shock of Class I luminaires not only relies on basic insulation, but also includes additional safety measures to connect the accessible conductive parts to the grounding protection conductors so that the accessible conductive parts do not become charged when the basic insulation fails.
The grounding terminal of the Class I luminaire has a grounding symbol. It should be noted that the metal casing of the Class I luminaire should be effectively grounded. If the lamp can touch the ballast, the ballast should also be effectively grounded.
Class II luminaires are protected against electric shock by not only basic insulation, but also additional safety measures such as double or reinforced insulation. In the event of a basic insulation failure, they can also rely on supplementary insulation. Lamps in plastic casings are generally Class 0 or Class II. It is best to purchase Class II lamps. Class II lamps have symbols. Class III luminaires are protected against electric shock by relying on the power supply as a safety extra low voltage, and the voltage inside the luminaire does not generate a voltage higher than the safety extra low voltage.
4. Instructions for using the lamp:
1 After buying the lamp, don't be busy installing it. You should carefully look at the markings of the lamp and read the installation instructions. Install the lamp according to the instructions and use the lamp according to the rules of use in the manual.
2 According to the light source parameters provided by the sign, replace the aging lamp in time, and find that the two ends of the lamp are red. The lamp should be replaced in time to prevent the ballast from burning out and other unsafe phenomena.
