Purchase instructions
Table lamp is the most common type of portable general lighting, and it is also an essential lighting product for students' desks and teachers' desks. The safety of products is particularly important due to the large age span of users and children involved. When purchasing, you should first consider the safety and quality of the lamp, and then consider the performance and appearance factors.
Note the following six items: 1. Enter the regular shop and buy regular goods. To formal invoices, do not buy products that are too cheap, buy products that have three guarantees, and purchase lamps that have a 3C certification mark.
2. Advertising is for reference only. It is very important to consult the inspection report. In particular, check whether the items such as protection against electric shock, durability test, and resistance to burning are qualified in the inspection report.
3. You should look at it three times. A look at the product logo is complete, the regular product logo is often more standardized, at least should mark the following: trademark and factory name, product model specifications, rated voltage, rated frequency, rated power. Check whether the product model is in line with the inspection report and safety certification model specifications, electrical parameters are identified correctly; 2 see the lamp power cord is CCC safety certification mark, external conductor cross-sectional area should be) 0.75 square millimeters; Whether the live body is exposed or not, the finger should not touch the live metal lamp after the light source is installed in the lamp holder.
4. Select the table lamp with higher protection against electric shock, according to the type of protection against electric shock, the lamp can be divided into 0, I, II and III categories. Most products sold on the market belong to category 0 or II. Type 0 lamps rely on basic insulation as protection against electric shock. In case of basic insulation failure, electric shock hazards are likely to occur. The protection against electric shock of Class III 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. You should try to buy a Class II fixture marked with a Class II return symbol.
5. When choosing a table lamp for children, it is best to avoid purchasing metal-enclosure table lamps with high heat sources such as incandescent table lamps and tungsten-halogen lamps. At the same time, attention should also be paid to the smoothness of the lamps at the time of purchase to avoid overturning the lamps when they are not placed. The lamp can be tilted 6 degrees to see if it is tipped over to determine the smoothness of the lamp.
