As an important lighting and decoration tool in the home, the purchase of lamps and lanterns takes an important position in the entire home. In addition to the selection of types and styles, the identification of the quality of lamps and lanterns is also very important, with regard to the safety of electricity for the whole family. At present, there are many kinds of lamps and lanterns, and the quality of products varies from one lamp to another. From lamps that have little difference in appearance, it is really necessary to carefully identify the lamps that are suitable for themselves and have good quality. Below, Xiao Bian will teach you a few ways to identify lamps.
| First, identify the appearance of the lamp |
When consumers purchase lamps, they should first look at the signs on the lamps to determine whether they meet their own requirements. The mark is an important basis for people to correctly install, use, and maintain. It is an extremely important safety requirement for ensuring personal and property safety. It is a basic requirement for the safety performance of lamps and lanterns. The rated power is particularly important. For example, for a lamp designed for 40W, since the rated power is not marked, the user is likely to install a 60W or 100W lamp, which may cause deformation of the shell, damage to the insulation, or even damage. Electric shock may cause fire. Marking is one of the safety requirements and should not be ignored.
1. It should be noted that the product is marked:
(1) See if the manufacturer's name and trademark, model, rated voltage, rated power, etc. are safe;
(2) Ceiling lamps, wall lamps, table lamps, and floor lamps that are intended to be installed on the surface of wooden materials, and those that are marked with F symbols.
2. Identification from protection against electric shock:
If you buy an incandescent lamp (such as a chandeliers, a wall lamp), put the lamp on. If there is no electricity, if you touch the lamp cap with a small finger, the protection against electric shock is basically satisfactory. If it is a fluorescent lamp (such as a recessed lamp, a fixed lamp), when the lamp is installed and the starter is installed, if no live parts are touched with a small finger when the power is not applied, the electric shock-resistance performance is basically in conformity with the requirements.
3. Identification of the cross-sectional area of ​​the conductor used in the luminaire:
The standard stipulates that the minimum cross-sectional area of ​​the wire used in the luminaire is 0.5mm/square, and some manufacturers use a wire cross-sectional area of ​​only 0.2mm/square meter in order to reduce the cost, and in the abnormal state, such as the start current jump in the fluorescent line. If not, the entire line will work with a start-up current. The start-up current will be larger than the normal operating current, which will cause the wire to burn out and the insulation layer to burn out. Short-circuiting will result in danger. The method of identification is: When buying, you can see whether the outer insulating layer of the lamp is marked with a mark, and the cross-sectional area of ​​the wire should be at least 0.5 mm/square.
