Identification of pros and cons of LED energy-saving lamps need to "look"

In life, many people do not know how to identify the advantages and disadvantages of LED energy-saving lamps, which led to the selection of LED energy-saving lamps brought some errors, are summarized mainly "five see."

Look at the packaging and trademark

National mandatory LED lighting products manufacturers in the packaging marked the following: rated voltage and voltage range, rated power, rated frequency.

In general, the quality of the trademark printing of good quality products, the font is clear, not easy to fall off, wipe with a soft damp cloth, clear and legible logo, not easy to eradicate, a manufacturer's trademark and related certification mark. Poor quality printing products, fonts fuzzy, easy to erase, no manufacturers of trademarks and related certification mark.

Second look LED tube appearance

Real LED energy-saving lamps, is the use of three color tube, tube white, hand cover to see more white. In addition, from the lamp point of view, you can put more than one lamp together, the better the shape and size of the tube is better machine bending forming, mostly large-scale production of the product. Product consistency, quality is easy to get guaranteed, interchangeability is better. Of course, the appearance can not crack, loose and interface was prized traces. In the installation, demolition process, the lamp should not be loose, tilted head phenomenon. Lamp plastic shell must choose the type of engineering plastics flame retardant. Ordinary plastic deformation and flammable, is prohibited for the production of energy-saving lamps. From the surface can easily determine the two, the latter surface is relatively smooth, shiny, the former surface with a frosted glass texture.

Third, look at the temperature of work

LED energy-saving lamps in normal working conditions, the temperature rise should be very low. Otherwise, LED energy-saving lamp life is very short. At the same time, energy-saving lamps lit, flashing quickly, or very dazzling fluctuations, indicating the quality of the energy-saving lamps.

Look at the start performance

LED energy-saving lamps start with two characteristics: First, the higher the temperature the easier to start; the second is the light off, will not flash. In addition, it is worth mentioning that a lot of LED

Energy-saving lamps open dark, which adversely affect the life of the lamp, LED energy-saving lamps should be equipped with power circuits and PCB board in its interior.

Five to see the interference

In our country, the electromagnetic compatibility has already been the electric appliance must pass the project, however, this project examination is very complex, the user purchases the lamp to see whether the package has passed

National electromagnetic compatibility test signs, the second is with a shortwave radio, when the lamp work, the radio is placed in the vicinity of the radio to shortwave no noise at the radio at the lower the measured lamp, the better the electromagnetic compatibility .
