How to determine the quality of LED lights

　　In life, many people do not know how to discriminate the quality of LED energy-saving lamps , LED lamps and thus to bring a selection of some of the errors are summarized there are " five to see ."

　　1. Look at the packaging and Trademark

　　National mandatory LED lighting products manufacturer marked on the packaging following: rated voltage, voltage range, rated power, rated frequency.

　　In general, good quality products, label printing quality , legible , easy to fall off , wipe with a soft damp cloth , signs legible and indelible , there are manufacturers of trademarks and related certification mark. Poor print quality and shoddy products , fuzzy fonts, easy to erase, no manufacturer 's trademarks and related certification mark.

　　2. See the appearance of LED lamp

　　The real LED energy-saving lamps , with tricolor pipe, white, hands over look whiter . Also, speaking from the lamp , the lamp can put more than just put them together, lamps good consistency of shapes and sizes , mostly bending molding machines , mostly mass-produced products. Consistency of the product is good, the quality is easier to be guaranteed, the interchangeability of better maintenance . Of course , it can not have cracks between loose and interfaces are prized appearance . During the installation , the demolition process , there should be no loose cap , head tilt phenomenon . Lights must choose the kind of engineering plastics flame retardant plastic case type . Ordinary plastic deformation and flammable , is prohibited for the production of energy-saving lamps . Can be simply determined from the surface of both , the latter surface is smooth, shiny , like frosted glass former surface texture.

　　3. Working temperature

　　LED energy-saving lamps in normal working condition, its temperature should be low. Otherwise , LED energy saving lamp life is very short. Meanwhile, when the energy-saving lights , have quickly flashing, either very harsh fluctuations, shows that there are quality problems of energy-saving lamps.

　　4. See the start performance

　　LED energy-saving lamps start with two characteristics : First, the higher the temperature the more likely to start ; Second, turn off the lights , do not flash . Also worth mentioning is that many LED

　　Energy-saving lamps opened very dark , which is detrimental lamp life , LED energy-saving lamps shall be provided with power supply circuit and PCB board in its interior .

　　5. Check the EMC interference

　　In China, the electromagnetic compatibility of electrical project must have been , however, that this project is very complicated to detect when the user purchases a lamp to see if the package through

　　National flag electromagnetic compatibility test , the second is with a shortwave radio , when the lights work , placed near the radio , shortwave radio to emit no more radio at low noise , electromagnetic compatibility test , the better lights .
