Lights nowadays are not only satisfying the needs of life, but also an important means of beautifying the home and mediating the atmosphere.
Common types of lamps
The types of commonly used lamps and lanterns generally include chandeliers, wall lamps, ceiling lamps, floor lamps, table lamps, and ceiling lamps.
The chandelier is a ceiling lamp that is suspended from the ceiling. They are all used as a whole.
Floor lamps and wall lamps are mainly used for the local lighting of the bedroom and the light is soft.
Desk lamps are mostly used to illuminate desks, with concentrated light, allowing users to concentrate and not interfere with the outside world.
Energy-saving lift lamps are mostly used in restaurants, which have the advantages of energy saving and easy operation.
Factors to Consider When Purchasing Fixtures
1, choose consumer satisfaction or after-sales service reliable home market.
2, to shop around, for the same style, the same brand of goods, from the quality, price, service and other aspects of comprehensive consideration.
3, modeling modern lighting fixtures are antique, innovative and practical three categories. The chandeliers, wall lamps, ceiling lamps, etc. are all developed in accordance with 18th century palace lamps. These lamps are suitable for larger social occasions. Modern lamps with unique shapes, such as various spotlights and bull-eye lamps, are innovative lamps. Usually daylight, writing desk lamps, floor lamps, bedside lamps, etc. are all traditional lamps. The styling of these three types of lamps should be pursued in a series when overall selection.
4, style according to their own artistic tastes and room conditions to choose lamps. Family with living room can use some stylish lamps in the living room, such as trigeminal chandelier, floral wall lamp, multi-section rotating floor lamp and so on. Households with relatively tight homes should not wear lamps that are too stylish. This will increase the sense of crowding. Rooms with a floor height of less than 2.8 meters should not be equipped with a chandelier. Only ceiling lamps can be installed to make the room look higher.
5, the color of the color lamps to obey the color of the entire room. In order to not destroy the overall color design of the room, we must pay attention to the shade of the lamp, the color of the shell and the color coordination of the wall, furniture and curtains.
6. The name, specification, quantity, price, and amount of the tiles must be specified on the invoice and contract.
7. Understand the names, addresses, contacts, and telephones of the organizers and manufacturers so that quality problems can be solved and resolved in a timely manner.
Identification of lamps
1, from the lamp's appearance to identify
1 The marking of the lamps and lanterns When buying lamps and lanterns, you should first check the markings on the lamps, such as trademarks, models, rated voltage, rated power, and determine whether they meet their 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, 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 housing and insulation damage. It may even cause electric shock and may cause fire.
2 From the protection against electric shock protection, attention should be paid to protection against electric shock. After the lamp is powered on, people must 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 light bulbs on, in the absence of electricity, such as the use of small finger touched live parts, the protection against electric shock is basically consistent.
Causes the lamp to prevent the electric shock to be inconsistent, generally uses the lamp socket that the lamp that does not meet the requirements or the lamp live parts does not cover and so on protects against the electric shock protection measures.
In addition, the standard stipulates that the minimum cross section of the wire used in the luminaire is 0.5mm2, and some manufacturers reduce the cost. The cross-sectional area of ​​the wire used in the product is only 0.5mm2, so that the wire can be charred and the insulation layer burns out. Short circuit, dangerous.
The method of identification is: when purchasing, you can look at the marks printed on the insulating layer outside the wires on the lamps. The cross-sectional area of ​​the wires should be at least 0.5mm2.
2, from the lighting structure identification
1. There should be no sharp edges on the entrances and exits of the metal pipes through which the wires pass, so as not to cut the wires and cause the metal parts to become live, causing electric shock.
2, table lamps, floor lamps and other portable lamps in the power cord inlet should be a wire holder, its role is to prevent the power cord push back to touch the heating element, the wire is too hot to cause the insulating layer to melt, the exposed wire and metal shell contact, shell Charged and lead to electric shock.
3. Identification of accessories used on luminaires 1 If electronic ballasts are used in the luminaires, luminaires equipped with anomalous protection electronic ballasts should be purchased. The so-called abnormal protection refers to an abnormality in the fluorescent line. The protection given in the state allows the electronic ballast to work normally.
If there is such an anomalous condition in use: when the lamp is used to the end of its life (if the lamp is not bright), the lamp itself is not conductive, but the two electrodes in the lamp have not broken yet. The current flowing through the output of the electronic ballast drastically increases. For this abnormal state, electronic ballasts should be protected to prevent damage to electronic components. If there is no such protection, once the lamp is broken, the electronic ballast is also broken. This is not allowed by the standard. of. In order to reduce the cost, some of the electronic ballasts used in the lamp factory will eliminate such anomalous protection measures and should be taken seriously.
2 In the lamp, an inductance ballast is used. Look for the mark on the ballast. Try to use a type with a higher Tw (such as Tw130). Especially when the cooling conditions of the lamp are poor, pay more attention to this point. Tw is the rated maximum operating temperature of the ballast coil. At this temperature, the ballast can operate continuously for 10 years.
