LED energy-saving lamps identify the five strokes


   LED energy-saving lamps because of its energy-saving effect is obvious, long life, no flicker effect, no noise, soft light and wide operating voltage range characteristics and increasingly popular with consumers. But the current market, many energy-saving lamps LED, good and bad quality. How in the lighting shop dazzling array of energy-saving lamps to buy their own satisfaction with the product? Through the "five to see" can identify the advantages and disadvantages of energy-saving lamps, described below.
   A look at packaging and trademark
   The state mandatory requirements LED lamp manufacturer products on the packaging marked the following: rated voltage, voltage range, rated power, rated frequency. Generally speaking, high-quality products, trademark printing quality, font clarity, easy to fall off, wipe with a soft damp cloth, signs clearly visible, easy to wipe, there are manufacturers of trademarks and related certification mark. Fake and shoddy products, poor quality printing, fuzzy fonts, easy to erase, no manufacturer's trademark and related certification mark.
   Second look LED tube appearance
   The real LED energy-saving lamps, is the use of three primary colors tube, tube white, covered by hand to see, more white. In addition, from the lamp point of view, you can put more than one lamp together, lamp shape and size of the consistency of the machine more than the formation of bending, mostly large-scale production of the product. Product consistency is good, the quality is easier to be guaranteed, the maintenance of the interchangeability is better. Of course, the appearance can not have cracks, loose and intertwined between the traces of pry. In the installation, removal process, the lamp should not be loose, tilted head phenomenon.
   The plastic shell of the lamp must choose the kind of engineering plastic flame retardant type. Ordinary plastic is easy to deform and flammable, is prohibited for energy-saving lamp production. From the surface can be a simple distinction between the two, the latter surface is more smooth, shiny, the former surface similar to the frosted glass texture.
   Three look at the work of the temperature
   LED energy-saving lamps in normal working condition, the temperature rise should be very low. Otherwise, LED energy saving lamp life is very short. At the same time, energy-saving lamps lit, there is a very fast flash, or very dazzling fluctuations, indicating that the quality of energy-saving lamps.
