How to identify the advantages and disadvantages of LED energy-saving lamps

In life, many people do not know how to identify the advantages and disadvantages of LED energy-saving lamps, so as to bring some errors in the selection of LED energy-saving lamps, and now sum up the main "five see."

A look at the packaging and trademark state mandatory mandatory LED lighting manufacturer's products on the packaging marked the following: rated voltage, voltage range, rated power, rated frequency.

Generally speaking, the trademark of high-quality products is of good quality and printed with clear characters and is not easy to fall off. Wipe with soft and damp cloth, the mark is clearly legible, it is not easy to wipe off, and there are manufacturers' trademarks and related certification marks. Fake and shoddy products have poor print quality, fuzzy fonts, and are easily erased. There are no manufacturer's trademarks and related certification marks.

Second, look at the appearance of LED lamps, real LED energy-saving lamps, is the use of three-color tube, tube white, covered by hand to see, more white. In addition, from the lamp point of view, more than one lamp can be put together to compare the better shape and size of the lamp tube are mostly machine bending forming, mostly large-scale production of products. Product consistency is good, quality is easier to ensure, and interchangeability during maintenance is better. Of course, there must not be cracks, looseness, and traces of cracks in the interface. In the process of installation and dismantling, there should be no loosening of the lamp head and a smashing phenomenon. The plastic shell of the lamp must be selected as the kind of engineering plastic flame retardant. Ordinary plastics are easily deformed and flammable, and are prohibited from being used in the production of energy-saving lamps. From the surface, it is easy to distinguish between the two. The latter surface is smooth and shiny, and the former has a frosted glass-like texture.

Three look at the work temperature LED energy-saving lamps under normal operating conditions, the temperature rise should be very low. Otherwise, the life span of LED energy-saving lamps is very short. At the same time, when the energy-saving lamp is lit, there is rapid flashing, or it is very dazzling, indicating that the energy-saving lamp has quality problems.

Four to see the start performance of LED energy-saving lamps start has two characteristics: First, the higher the temperature is easier to start; Second, the light is turned off, will not flash. In addition, it is worth mentioning that many LEDs

Energy-saving lamps turn on very dark, which is detrimental to lamp life. LED energy-saving lamps should have power circuits and PCBs inside.

Five to see 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 a user purchases a lamp, he or she sees whether there is a mark that passes the national electromagnetic compatibility test on the packaging, and the second is with one Short-wave radios, when the light is working, put the radio in the vicinity, the lower the noise is, the lower the noise is emitted by the radio and the short-wave radio, the better the electromagnetic compatibility of the lamp under test.
