In life, many people do not know how to identify the good and bad LED energy-saving lamps, which brings some misunderstandings to the selection of LED energy-saving lamps.
A look at the packaging and trademarks state mandatory LED lighting manufacturers products on the outer packaging marked the following: rated voltage, voltage range, rated power, rated frequency.
Generally speaking, the quality of the trademark printing of high-quality products is good, the font is clear, it is not easy to fall off, and it is wiped with a soft damp cloth. The mark is clear and identifiable, it is not easy to wipe off, and there are trademarks of manufacturers and related certification marks. Counterfeit products have poor printing quality, fuzzy fonts, easy to erase, no manufacturer's trademark and related certification marks.
Second, look at the LED lamp tube appearance of the real LED energy-saving lamps, is to use three primary color tubes, tube white, cover by hand to see, whiter. In addition, from the perspective of the lamp tube, it is possible to compare a plurality of lamps together, and the shape and size consistency of the lamp tube are mostly bent and formed by a machine, and most of them are products produced on a large scale. The consistency of the product is good, the quality is easy to be guaranteed, and the interchangeability during maintenance is better. Of course, there should be no cracks, looseness, and traces between the interfaces. During the installation and disassembly process, the lamp cap should not be loose or smashed. The plastic shell of the lamp must be selected from the flame retardant type of engineering plastic. Ordinary plastics are easily deformed and flammable, and are prohibited from being used in the production of energy-saving lamps. The two can be easily discriminated from the surface. The latter surface is smooth and shiny, and the surface of the former has a texture similar to frosted glass.
Third, look at the temperature of the work LED energy-saving lamps under normal working conditions, the temperature rise should be very low. Otherwise, the LED energy saving lamp has a very short life. At the same time, when the energy-saving lamp is lit, there is a rapid flashing, or it is very glaring, indicating that the energy-saving lamp has quality problems.
Four look at the startup performance LED energy-saving lamp startup has two characteristics: First, the higher the temperature, the easier it is to start; the second is that the light is turned off and will not flash. In addition, it is worth mentioning that many LEDs
The energy-saving lamp is very dark, which is unfavorable for the life of the lamp. The LED energy-saving lamp should be provided with a power circuit and a PCB board inside.
Five look at the interference situation In China, electromagnetic compatibility is a project that must be passed by electrical appliances. However, the detection of this project is very complicated. When users buy lamps, they will see whether there is a mark on the packaging that passes the national electromagnetic compatibility test. Short-wave radio, when the lamp is working, put the radio nearby, the lower the noise emitted by the short-wave radio station, the better the electromagnetic compatibility of the lamp under test.
