The types of household lamps commonly used are chandeliers, wall lamps, ceiling lamps, floor lamps, table lamps, and ceiling lamps. Regardless of the kind of lighting used, the most important thing is whether its safety indicators are qualified. The owner can identify the following aspects.

(1) Identification from the appearance of lamps

1 lamp marking

When purchasing a lamp, you should first check the markings on the lamp, such as the trademark, model, rated voltage, rated power, etc., to determine whether it meets its own requirements. Marking safety is a basic requirement in the safety performance of lamps and lanterns, among which the rated power is particularly important. For example, a lamp designed for 40 watts, because of the unmarked rated power, the user is likely to install a 100-watt lamp, which may cause the deformation of the shell and the insulation damage. It may even cause electric shock and may cause fire.

In addition, the standard stipulates that the smallest cross-section of wires used in luminaires is 0.5 square millimeters. Some manufacturers reduce the cost, and the cross-sectional area of ​​the wires used in the products is less than 0.5 square millimeters. This may cause charring of the wires and burning of the insulation layer. Short circuit, dangerous. At the time of purchase, look at the markings printed on the insulating layer outside the wires on the luminaire.

2 from the protection against electric shock protection

Should pay attention to protection against electric shock, after the lamp is energized, people should not touch live parts and there will be no risk of electric shock. If you buy incandescent lamps (such as chandeliers, wall lamps), put the lamp on without electricity, if you touch the live parts with your little fingers, the electric shock protection performance is basically consistent. That is basically people are not touched live parts, live parts should be something to block.

Caused by lamp electrical shock performance does not meet the standards, generally use non-compliant lampholders or lamps live parts without cover and other protection measures against electric shock.

(2) Structure identification from lamps

(1) There shall be no sharp edges on the entrances and exits of metal pipes passing through the conductors. It is better to have an insulating protective layer so as not to cut the conductors and cause electrification of the metal parts, resulting in electric shock.

2 Removable lamps such as table lamps and floor lamps should have a wire holder at the entrance of the power cord. The function is to prevent the heating element from being touched when the power cord is pushed back. The wire is too hot and the insulating layer melts. The exposed wire contacts the metal shell and the shell is charged. Causes an electric shock.

(3) Identification of accessories used on luminaires

1 If electronic ballasts are used in the luminaire, luminaires equipped with anomalously protected electronic ballasts shall be selected. The so-called anomalous protection refers to the protection given when an abnormal state occurs in the fluorescent line, so that the electronic township The flow meter still works. First of all, ballast products have to be certified by the country and can be used in accordance with the standards.

2 If the lamp is an inductive ballast, look at the ballast's logo and try to use a type with a higher Tw (such as Tw130). Especially when the lamp's cooling conditions are poor, it should be noted. Tw is the rated maximum operating temperature of the ballast coil. At this temperature, the ballast can operate continuously for 10 years.
