① When buying lamps, you should first look at the marks on lamps, such as brand, model, rated voltage and rated power, to judge whether they meet your own use requirements. Marking safety is the basic requirement in the safety performance of lamps, among which the rated power is particularly important. For example, if a lamp with a design of 4W is not marked with the rated power, users are likely to install 6W or 1W bulbs, which may cause shell deformation, insulation damage, even electric shock and fire.

② From the identification of electric shock protection, attention should be paid to electric shock protection. After the lamps are electrified, people should not touch the live parts, so there is no danger of electric shock. If you buy incandescent lamps (such as chandeliers and wall lamps), install the bulbs. If you can't touch the live parts with your little fingers without electricity, the electric shock protection performance is basically consistent. Non-conformity of electric shock protection of lamps and lanterns is generally caused by adopting non-conforming lamp holders or non-covered live parts of lamps and lanterns. In addition, the standard stipulates that the minimum cross-section of wires used in lamps and lanterns is .5mm2. In order to reduce the cost, some manufacturers only use .5mm2 for the cross-section of wires used in products, so that the wires can be scorched by friendship, and the insulation layer will be short-circuited after being burnt out, resulting in danger.

the identification method is: when buying, you can look at the marks printed on the insulation layer outside the conductor on the lamp, and the cross-sectional area of the conductor should be at least .5mm

2. Identify from the structure of the lamp

a. The entrance and exit of the metal pipe through which the conductor passes should have no sharp edges, so as to avoid cutting the conductor, causing the metal parts to be charged and causing the danger of electric shock.

b, table lamps, floor lamps and other portable lamps should have a wire holder at the entrance of the power cord, which is used to prevent the power cord from touching the heating element when it is pushed back, and the insulation layer will melt due to overheating of the wire, and the exposed wire will contact with the metal shell, and the shell will be charged, resulting in electric shock.

3. Identification from accessories used on lamps

① If electronic ballasts are used in lamps, lamps equipped with abnormal protection electronic ballasts should be purchased. The so-called abnormal protection refers to the protection given when an abnormal state occurs in the fluorescent circuit, so that the electronic ballasts can still work normally.
