Critical to teach you to distinguish material of lamps and lanterns

The types of commonly used lamps and lanterns to roughly chandeliers, wall lamp, absorb dome light, floor lamp, desk lamp, embed dome light, etc. No matter choose what kind of lamps and lanterns, the most important thing is the safety index is unqualified, the owner can be identified from the following several aspects.

　　( 1) Identified in the appearance of lamps and lanterns of lamps and lanterns of

tag

buy lamps and lanterns should first check the mark in the lamps and lanterns, such as trademark, type, rated voltage, rated power, etc. , whether it can meet the demands of their own use. Tag security is the basic requirement of the safety performance of lamps and lanterns, the rated power is particularly important, such as a design to 40 watts of lamps and lanterns, because the marked rated power, the user is likely to 60 - or 100 - watt light bulb, it may cause the shell deformation, insulation damage, even cause electric shock, and may cause fire.

in addition, standard, lamps and lanterns on the use of wires minimum cross section of 0. 5 mm square, some manufacturers to reduce costs, and on the products with the cross-sectional area of less than 0. 5 mm square so that I may make burned in wire insulation short circuit occurred after burn, at risk. When buying can have a look at the wire insulation layer printing some mark in the lamps and lanterns.

　　( 2) From the differential protection against electric shock

should pay attention to the protection against electric shock, electric lamps and lanterns, people do not want to touch live parts, don't get an electric shock danger. If I buy the incandescent lamps and lanterns, Chandeliers, wall lamp, for instance) , the light bulb installed under the condition of no electricity, such as touch live parts, with pinky, prevent to get an electric shock is largely in line with performance.

cause electric shock proof performance of lamps and lanterns is not in conformity with the standards, is generally adopted is not in conformity with the requirements of the lamp holder or live parts of lamps and lanterns is not caused by electric shock proof protection measures such as casing.

　　( 3) From the structure identification of lamps and lanterns

wire through the tube entrance should be no sharp edges, in order to avoid cutting wire, metal parts charged, get an electric shock risk.

table lamp, floor lamp, such as portable lamps and lanterns should be the entrance of the power cord wire fixed frame, its role is to prevent the power cord back into touch the heating element, insulation layer melt line overheat, bare wire contact with the metal shell, shell charged and cause electric shock.

　　( 4) Use the attachment to identify from the lamps and lanterns

if the lamps and lanterns is used in the electronic ballast, should be equipped with abnormal protection electronic ballast of choose and buy lamps and lanterns, the so-called abnormal protection refers to when there is an abnormal condition in the fluorescent circuit for protection, make the electronic ballast can still work normally.

the lamps and lanterns, such as using inductance ballasts, see the signs on the ballast, try choosing a higher Tw ( Such as Tw130) Especially poor heat dissipation condition of lamps and lanterns, more attention should be paid to it. Tw is the highest working temperature rating of the ballast coil at the temperature, the ballast can work continuously for 10 years.
