How to determine the quality of LED lamps

  As the state vigorously promote LED lighting , LED lighting makes the rapid growth and popularity of the product . Since the product is a new product of LED lighting industry , the ordinary people of their very strange, and even some not very strong technology manufacturers and vendors, customers misinterpreted , leading to a regular user of LED lighting products misleading to LED products promotion and use to bring a certain obstacles. Help the majority of users correctly understand and judge the quality of LED products, good or bad , here are ten simple discrimination quality LED light is good or bad way .

 How to determine the quality of LED lamps

  1, select from the brand. Should choose a brand or trademark with "R" registered enterprise products , LED lights beautifully shiny appearance , product trademarks , models, specifications printed writing clear and beautiful, there should be no distortion paint, uneven color and so on.

  2, LED lamp usually made of aluminum radiators, radiator and air contact area as large as possible , it is a good heat , the whole light stable, long- life light is small ; bulbs and ceiling spotlights do not have too much holes to avoid mosquitoes during use to climb into the impact of the lighting effect or cause unnecessary damage.Color obvious error

  3, LED bulb, ceiling spotlights, track lighting , if shining on a white wall , there should be no stain, color rings, etc. , if such a phenomenon, indicating bead lamp inferior .

  4 , in the open LED lights with light -emitting electricity have a few tenths of seconds to the time difference between , is a normal phenomenon, usually the lamp is driven with a constant current source IC integrated circuit , the steady flow regulator performance better, job stability.

  5 , work lamp body heat is not too high or uneven , if such a phenomenon, indicating lamp design or production process problems, large lumen easily damaged.

  6 , due to the high brightness LED lights , two brands of the same type of light , under the same conditions, with eyes straight way to compare observed , it is difficult to determine the level of brightness , but this can easily damage the eyes eyesight. Usually we recommend using a piece of paper to cover the light , white light attenuation through , and then comparing the brightness so that it is easier to see the differences in lighting , the brightness of the higher , the better . Further , the color temperature closer to the optimal color of the sunlight .

  7, if time permits , you can take the same specifications brightness compare two lamps do first , and then one of them lights continuously lit week , and then the lamp brightness before comparison with comparable , if not obvious , then dimmed , Description this small light decline , better quality light source lamp beads .

  8 , for those ceiling spotlights, track lights , high-power integrated light source , COB high power light source , and you can easily remove the mask visible light bead multi-chip products , can be used , such as power- saw bead lamp is lit after close your eyes , then turn off the power at the same time open your eyes , you will see light bead chip peripheral vision , peripheral vision disappear if too much time error , indicating the uneven quality of the chip lamp beads , lamp beads inferior goods or pay chip . Easy to damage the whole lamp life is short, easy to buy.

  9, LED lights at work, around the time of refrigerators, air conditioners , water heaters and other electrical power to start , there should be no subsequent change in light and dark , if such a phenomenon , indicating that the LED light is not constant current or constant voltage drive , this has a certain impact on the life of the lamp.

  10 , the community spread an observation camera with LED lights to judge its quality through the phone screen , so that light is good or bad judgment is not quite accurate , striped scroll blinking certainly not good, no not like flashing streaks rolling because our different phone screen and camera , they scan refresh rate is different for those driving low-end RC Buck products that sensitivity is not the same .
