Fake LED ceiling six symptoms"

Introduction: as a large and wide range of lamps and lanterns, ceiling lamp production enterprises, many enterprises have annual production, and continue to have small-scale enterprises to join. A lot of small businesses choose the best products to imitate, and then purchase parts and components. Because many companies do not understand the requirements of the product, in the process of imitation by the market and the impact of cost factors and produce a variety of deviations do not meet national standards. The status of the lighting industry led to the quality of the ceiling lamp at a low level. To sum up, the main problems of the ceiling lamp.

NO.1

The cross-sectional area of the internal wiring and external wiring of the ceiling lamp is less than 0.5mm2/0.75mm2. Too small wire cross-sectional area is a big hidden danger of the lamp safety. Once the fault occurs, it will produce a large current, and the wire will be burned before the operation of the power system.

NO.2

Ceiling lamp durability does not meet the standard requirements. The main reason is the fluorescent ceiling lamp rectifier used does not pass, especially electronic rectifier without abnormal state protection under abnormal conditions, electronic rectifier will immediately damaged or burned, and the lamp can not continue to use or become dangerous.

NO.3

The insulating material used in the ceiling lamp is not heat resistant and fireproof. In particular, the use of fluorescent lamps more insulating materials, such as lampholders, starters, etc., this problem is very prominent. Fixed charged parts of light in place or protection against electric shock must be able to heat and refractory insulation materials, insulation materials to prevent these long-term overheating and spark caused deformation, combustion risk, so that the original protection against electric shock performance failure.

NO.4

The processing technology of the ceiling lamp is rough, and there are hidden dangers in the process of assembly and use. Such as lighting thin edges have acute angle, may make the installation and maintenance personnel from harm; internal wiring at an acute angle or burr, the installation process is easy to internal insulation piercing, short circuit, electric shock and other security risks.

NO.5

The structural design and selection of the ceiling lamp does not meet the requirements of the protection against electric shock. This will lead to people in the installation of lamps and lanterns to complete the use or change the light source, starter to open the lamp, easy to touch live parts. For example, do not meet the requirements of the screw socket lamp holder, the exposure does not meet the design of charged pins exposed, fluorescent lamp lamp structure caused by the unreasonable requirements of making printed circuit board exposed open type electronic rectifier, the security structure caused by lamp protection against electric shock do not meet.

NO.6

Ceiling lamp disturbance voltage exceeds the standard requirements. The disturbance voltage is a kind of radio disturbance, and its harm will affect the use of electrical appliances in a large frequency range. At present, a large number of electromagnetic harassment has formed the environmental pollution. When the disturbance voltage exceeds the limit, it will affect the normal operation of the radio and television reception and instrument and equipment.
