Six symptoms of fake and inferior LED ceiling lamps

Six symptoms of fake and inferior LED ceiling lamps. As a large and wide range of lighting products, there are many ceiling lamp manufacturers, and companies are changing production every year, and small-scale enterprises continue to join. Many small companies just choose hot-selling products to imitate, and then purchase parts and assemblies. Because many companies don't know much about product requirements, they are affected by market and cost factors in the process of imitation, and various deviations that do not meet the requirements of national standards have occurred. The current situation of the lighting industry has caused the quality of ceiling lamps to be at a relatively low level. To sum up, the ceiling lamps mainly have the following problems. The cross-sectional area of u200bu200bthe internal wiring of the ceiling lamp/the cross-sectional area of u200bu200bthe external wiring is less than .mm/.mm. Too small a wire cross-sectional area is a major hidden danger to the safety of the lamp. Once a fault occurs and a large current is generated, the wire will be burned before the power supply branch insurance system operates, which will lead to safety accidents such as fire or electric shock. .The durability of ceiling lamps does not meet the standard requirements. The main reason is that the rectifier used in the fluorescent ceiling lamp does not turn off, especially the electronic rectifier has no abnormal state protection device. Under abnormal conditions, the electronic rectifier will be damaged or burned out immediately, and the lamp cannot be used or become dangerous. .The processing technology of ceiling lamps is rough, and there are safety hazards in the process of assembly and use. If there are sharp corners at the corners of the thin plate of the lamp, installation and maintenance personnel may be injured; there are sharp corners or burrs in the internal wiring, and the internal wire insulation layer is easy to pierce during the installation process, and there are safety hazards such as short circuit and electric shock. .The disturbance voltage of ceiling lamps exceeds the standard. Disturbance voltage is a type of radio disturbance, and its hazard is that it will affect electrical appliances in a large frequency range. At present, the large amount of electromagnetic disturbance has formed environmental pollution. When the disturbance voltage of the lamp exceeds the limit, it will affect the surrounding radio and television reception and the normal operation of the instrumentation equipment, resulting in the failure of normal listening and watching of radio and television and the failure of the instrument control. .The structural design of the ceiling luminaire or the selected key components do not meet the requirements for protection against electric shock. This will cause people to easily touch the live parts when the lamp is installed and used, or when the light source is changed or the starter is turned on. For example, non-compliant screw lamp holders expose the lamp cap, non-compliant fluorescent lamp holders expose the live pins, and the unreasonable design of the lamp structure exposes the printed circuit board of the open electronic rectifier. These unsafe structures cause the lamp to prevent electric shock. Protection does not meet. .Insulating materials used in ceiling lamps are not heat-resistant and fire-resistant. In particular, there are many insulating materials used in fluorescent lamps, such as lamp holders, starters, etc., and this problem is very prominent. Insulating materials for fixing live parts in luminaires or protecting against electric shock must be heat-resistant and fire-resistant to prevent these insulating materials from being deformed and burning due to long-term overheating and electric sparks, which will invalidate the original anti-shock protection performance of the luminaire .
