To choose a lighting fixture with higher safety performance, pay attention to the following aspects.

1. Marking on the product: See if the manufacturer's name and trademark, model, rated voltage, rated power, etc. are safe;

2. Protection against electric shock. The electric shock caused by the lamps and lanterns is generally due to the use of lamp holders or lamps that do not meet the requirements, and the live parts are not covered by covers and other protection measures against electric shock. It is normal that the bulb is screwed in when it is used. After the lamp is powered on, people should not touch live parts.

3. Cross-sectional area of ​​wires used in luminaires: At the time of purchase, it is possible to look at the marks printed on the insulating layer outside the wires on the luminaire. The minimum cross-sectional area of ​​the wires used in the stipulated lamps is 0.5mm/square. The cross-sectional area of ​​some conductors used for substandard products is only 0.2mm/square. This kind of wire will scorch the wire in an abnormal state and cause a short circuit after the insulation layer burns out.

4. The structure of the lamps:

(1) There should be no sharp edges on the metal pipes through which the wires pass, so as not to cut the wires and cause electrification of the metal parts, resulting in electric shock.

(2) Table lamps, floor lamps and other portable luminaires shall have a wire holder at the entrance of the power cord to prevent the wires on the terminals from coming off when the wire is subjected to pulling force, causing electric shock to the live metal shell; in addition, the wire holder can also be used. Prevent the heating element from touching the power cord when it is pushed back, causing the insulation to melt when the wire is overheated. The exposed wire comes into contact with the metal shell and the shell is charged, resulting in electric shock.
