| To identify from the appearance of the lamp
① lamps, marker lamps should be purchased first look at the markings on the lamp, such as trademark, model, rated voltage, rated power to be, determine if it meets their own use. Mark security lighting in the safety performance requirements, which rated power is particularly important, such as a design for 40W lamps, the rated power is not marked, the user is likely to install 60W or 100W bulbs, it is possible to deform the case, insulation damage and even cause electric shock, and may also cause a fire.
② Protection against electric shock identification should be noted that the protection against electric shock, lamp power, the people should not touch live parts, there will be no risk of electric shock. If you buy the tools (such as chandeliers, wall lamps, incandescent lamps), the lamp put something in the case of no electricity, such as the little finger to touch live parts, electric shock performance is in line with. Resulting in fixtures against electric shock does not conform with generally cover electric shock protection measures due to the lamp or lamps do not meet the requirements of live parts, not containing added. In addition, the standards require that lamps used on the minimum conductor cross section of 0.5mm2, some manufacturers to reduce costs in the product wire cross-sectional area of only 0.5mm2, the fraternity can make the wires charred, burned insulation occurred after short-circuit, resulting in danger.
Identification method: the time of purchase can look at the fixture wire insulation layer printed signs are the wire cross-sectional area should be at least 0.5mm |
