Nowadays, modern urban life is busy and tense, and a warm home can bring everyone the most relaxing leisure time. But how can you make your home warm and comfortable? With a little skill, you can easily create a pleasant home. Help you have a relaxed and comfortable life.

In the big stores, you can purchase the products that have the "Three Guarantees" commitment and purchase the lamps with the CCC certification mark.

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.

Choose 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 lamps rely on basic insulation as protection against electric shock. In the event of failure of basic insulation, electric shock hazard is likely to occur.

The anti-shock protection of luminaires not only relies on basic insulation, but also includes additional safety measures, that is, connecting the accessible conductive parts to the grounding protection wires, so that the accessible conductive parts are not charged when the basic insulation fails.

There is a grounding symbol next to the grounding terminal of the luminaire. It should be noted that the metal casing of the Class I luminaire should be effectively grounded. If the lamp changer 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.

Instructions for using the luminaire:

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.
